Protecting shoreline communities from tsunamis is a struggle, especially in less developed regions of the world because tsunamis are unpredictable. These phenomena have a higher effect on low-income shoreline families.
Tsunamis can be defined as giant ocean waves due to earthquakes and/or volcanic activity that occur under the sea.
Tsunamis may devastate entire shoreline communities because they are unpredictable and they speed along like a jet plane.
Tsunamis mainly affect shoreline low-income families in developing countries because the houses in which these people live in developing countries are rudimentary.

Why don't the hydrolytic enzymes Within lysosomes destroy each other?
Answer:
A lysosome is a membrane-bound cell organelle that contains digestive enzymes. They break down excess or worn-out cell parts. They may be used to destroy invading viruses and bacteria. If the cell is damaged beyond repair, lysosomes can help it to self-destruct in a process called programmed cell death, or apoptosis.
Explanation:
which type of organism can use photosynthesis to make food
Answer:Plants
Plants, algae, and a group of bacteria called cyanobacteria are the only organisms capable of performing photosynthesis (Figure 1). Because they use light to manufacture their own food, they are called photoautotrophs (literally, “self-feeders using light”).
Explanation:
Answer:
All plants with green leaves, from the tiniest mosses to towering fir trees, synthesize, or create, their own food through photosynthesis. Algae, phytoplankton, and some bacteria also perform photosynthesis. Some rare autotrophs produce food through a process called chemosynthesis, rather than through photosynthesis.

A hummingbird may need to consume up to 50% of its body weight in sugar each day, just to meet its energy needs. Some of this energy is stored and some is used for metabolic activities, but much of the energy is
A)
converted into amino acids needed for the production of starch
B)
released as heat energy back into the hummingbird's environment
C)
changed into radiant energy, which can be used by plants for photosynthesis
D)
used to synthesize inorganic compounds necessary for cellular respiration
Energy conversions are common in nature. Much of the energy from the breakdown of the hummingbird body weight is released as heat energy back into the hummingbird's environment.
According to the laws of thermodynamics, energy is neither created nor destroyed but is converted from one form to another. Living things take in food to release energy to carry out their daily activities.
Sometimes, energy is obtained from the breakdown of body fat. In either case, much of this energy is released back into the environment as heat energy.

The brain is well protected against microbial invasion by cellular barriers, such as the blood-brain barrier (BBB) and the blood-cerebrospinal fluid barrier (BCSFB). In addition, cells within the central nervous system (CNS) are capable of producing an immune response against invading pathogens.
Researchers identify a gene in cockroaches that is responsible for their ability of nerve regeneration. How might it be possible for this gene to be used in treating human paralysis?
This gene could be analyzed to determine its homology level with a human gene, which then could be restored in its normal expression. This strategy can restore the normal phenotype in defective human cells.
Sequence homology, which refers to the level of evolutionary relationship among genetic or proteins sequences, is a fundamental subject matter to determine gene function.
From this approach (sequence homology search), researchers can identify valuable genes involved in diseases in which the restoration of their normal expression levels can be used to restore the normal phenotype in defective cells.
In this case, the identification of a gene in cockroaches that is responsible for nerve regeneration could be used for subsequent identification of a human homologous gene sequence, which then can be restored in order to treat human paralysis.

Explanation:
five (5) kidney diseases their symptoms and their effect
Answer:
Kidney failure occurs when your kidneys lose the ability to sufficiently filter waste from your blood. Many factors can interfere with your kidney health and function, such as:
toxic exposure to environmental pollutants or certain medications
certain acute and chronic diseases
severe dehydration
kidney trauma
Your body becomes overloaded with toxins if your kidneys can’t do their regular job. This can lead to kidney failure, which can be life-threatening if left untreated.
Usually, someone with kidney failure will have a few symptoms of the disease. Sometimes no symptoms are present. Possible symptoms include:
a reduced amount of urine
swelling of your legs, ankles, and feet from retention of fluids caused by the failure of the kidneys to eliminate water waste
unexplained shortness of breath
excessive drowsiness or fatigue
persistent nausea
confusion
pain or pressure in your chest
seizures
coma
Symptoms of early-stage kidney disease may be difficult to pinpoint. They’re often subtle and hard to identify. If you experience early signs of kidney disease, they may include:
decreased urine output
fluid retention that leads to swelling in limbs
shortness of breath
A sudden loss of blood flow to your kidneys can prompt kidney failure. Some conditions that cause loss of blood flow to the kidneys include:
a heart attack
heart disease
scarring of the liver or liver failure
dehydration
a severe burn
an allergic reaction
a severe infection, such as sepsis
High blood pressure and anti-inflammatory medications can also limit blood flow.
When your body can’t eliminate urine, toxins build up and overload the kidneys. Some cancers can block the urine passageways, such as:
prostate (a most common type in men)
colon
cervical
bladder
Other conditions can interfere with urination and possibly lead to kidney failure, including:
kidney stones
an enlarged prostate
blood clots within your urinary tract
damage to your nerves that control your bladder
Acute intrinsic kidney failure can result from direct trauma to the kidneys, such as physical impact or an accident. Causes also include toxin overload and ischemia, which is a lack of oxygen to the kidneys.
The following may cause ischemia:
severe bleeding
shock
renal blood vessel obstruction
glomerulonephritis

What is the difference between diffusion and osmosis?
What makes a membrane semipermeable?
What characteristics of a molecule affect whether it can pass through the plasma membrane of a cell?
In the simulation, when protein molecules were evenly distributed on both sides of the membrane, was the solution isotonic, hypertonic, or hypotonic?
Which direction was water flowing?
In the simulation, when protein molecules were more highly concentrated on the inside of the cell than outside of the cell, was the solution isotonic, hypertonic, or hypotonic?
Which direction was water flowing?
Why is it important that the plasma membrane surrounding cells is semipermeable?
What would happen if it were not semipermeable?
1) Diffusion : Is the movement of molecules / ions from a region of higher to lower concentration. It may or may not occur across a semi permeable membrane.
In diffusion there is no challenge involved as it is along the concentration gradient, but in active transport movement of molecules occur against concentration gradient ie; from lower to higher concentration.
2) For active transport, energy is vital for movement, in this case protein molecules function as molecular pumps to enable the cell accumulate glucose/ions, against concentration gradient. Here metabolic energy ATP is required.
3)Facilitated diffusion is a type of passive transport in which ions/molecules cross the semi permeable membrane because permeases present in the membrane facilitate the transport.
Like simple diffusion facilitated diffusion doesn't require metabolic energy and simply occurs across the concentration gradient.
4) Osmosis : is movement of water from hypotonic solution (lower concentration) to hypertonic solution (higher concentration) through a semi permeable membrane.
The cell membrane being permeable to water allows to and from movement of water molecules along the concentration gradient.

Your answers may vary, but these sample answers are a model to follow.
Diffusion is the process of a substance moving from an area of high concentration to an area of lower concentration. Osmosis is a type of diffusion where water moves across a semipermeable membrane still from an area of high concentration of water to an area of lower concentration of water. This corresponds to water moving from an area with a low concentration of solute to an area with a higher concentration of solute.
A semipermeable membrane allows some substances to pass through it.
The plasma membrane of a cell allows small uncharged molecules to pass through it, but not large molecules and not charged ions.
The protein molecules were evenly distributed on both sides of the membrane, so this solution was isotonic.
In an isotonic solution, water moves both in and out of the cell, which was observed in the simulation.
The protein molecules were more highly concentrated on the inside of the cell, so this solution was hypotonic.
In hypotonic solutions, water moves into the cell to help dissolve the higher amount of solute inside the cell, which was observed in the simulation.
A semipermeable cell membrane is important to allow some molecules, like proteins, to be more highly concentrated inside the cell than outside the cell. If the cell membrane were permeable, the molecules on the inside of the cell would exit the cell and be evenly distributed in the cell and in its environment.
If the cell membrane were not permeable at all, the cell would not be able to receive nutrients from its environment.
Diffusion and osmosis has one difference which is the presence of semi-permeable membrane.
What is the difference between diffusion and osmosis?Diffusion is the movement of particles from an area of higher concentration to one of lower concentration while on the other hand, osmosis is the movement of particles from a semipermeable membrane.
Cell membrane is selectively permeable which only allows some molecules inside the cell because of its structure. So we can conclude that diffusion and osmosis has one difference which is the presence of semi-permeable membrane.
When protein molecules were evenly distributed on both sides of the membrane, the solution will be isotonic because of the same quantity on both sided. There is no movement of water in the body.
When protein molecules were more highly concentrated on the inside of the cell than outside of the cell, the solution will be hypotonic because of the less amount of water in the body.

Explanation:
What are the 4 steps of protein synthesis?
Answer:
In every eukaryotic cell, such as plants and animals, there is DNA in the nucleus. The nucleus is an area surrounded by a membrane (nuclear membrane) which has some pores for materials to enter and exit, but these are controlled.
The DNA is the cell's instructions, it is a series of code that can be transcribed and translated to make proteins. As in the image below DNA is a series of bases attached to a sugar phosphate backbone and bonded to another base pair to made a ladder, this ladder is twisted making the shaped called a double helix . There are four base pairs: Adenine (A), Thymine (T), Guanine (G), and Cytosine (C).
The bases have bases they bond to making complementary base pairs , A and T bond together while the C and G bond together. on each strand of DNA one end is labelled 5' (read as 5 prime) and other end is the 3'. The 5' end base pairs of one strand are always attached to the 3' end of the complementary strand. Labelling the ends helps us to describe in which direction DNA is read.
Since the DNA cannot leave the nucleus , copies of the section needed to make the protein are made, this is called transcription.
This done by first opening the double helix with an enzyme called DNA Helicase. Another enzyme called RNA polymerase will match new bases to the original DNA attaching them in a long strand of mRNA. When the enzyme reaches the end the strand will be removed and the DNA can close.

do you think carbon sinks can ever completely reverse global warming, why or why not?
Answer:
Explanation:
Framed in this way, the problem of climate change becomes not one of simply producing greenhouse gas, but how quickly we do so when compared with the Earth’s natural ability to soak it up again. And it makes that natural ability – the continuing capacity of forests and oceans to act as carbon sinks – as significant a factor in deciding the likely course of rising temperatures in the near future as intended controls on our greenhouse gas emissions. Yet many people are unaware of this side of the carbon balancing equation. And if they are, they take it for granted – they expect that forests and oceans and other carbon sinks will continue to act as our environmental get-out-of-jail-free card.
Or, more accurately, our go-to-jail-slightly-slower card. While sinks have managed to grab about half the carbon released as human pollution in recent centuries, the rest steadily accumulates in the atmosphere. The forests and oceans simply can’t suck it in fast enough. At the last count, atmospheric levels of carbon dioxide registered almost 412 parts per million (ppm) and rising. That’s a 47 per cent jump since the beginning of the industrial age, when the concentration was near 280 ppm, and an 11 per cent rise since just 2000, when it was near 370 ppm. Without our natural carbon sinks working to buffer the impact, that figure would probably be closer to 700ppm today.
It makes sense, then, that the future behavior of Earth’s massive carbon sinks – and specifically the question of whether they will continue to bail us out by taking in carbon dioxide – is a key topic of research for scientists. How will tropical forests respond to warmer temperatures? Will ocean currents continue to carry carbon to the depths? What happens to the pace of climate change if the carbon-catching capacity of these sinks weakens?
