A balloon is filled with helium in an airplane, where the air pressure is 81 kPa. The filled balloon has volume of 4.2 L. When the plane lands, the cabin is depressurized to the outside air pressure, which is 94 kPa. If the temperature of the balloon remains the same, what is the new volume of the balloon?
Answer:
3.62L
Explanation:
Using Boyle's law equation i.e
P1V1 = P2V2
Where;
P1 = initial pressure
V1 = initial volume
P2 = final pressure
V2 = final volume
According to information provided in this question, P1 = 81kPa, P2 = 94kPa, V1 = 4.2L, V2 = ?
P1V1 = P2V2
81 × 4.2 = 94 × V2
340.2 = 94V2
V2 = 340.2/94
V2 = 3.619
V2 = 3.62L
which mosquito cause malaria?
Answer:
Anopheles mosquitoes
Explanation:
Malaria is a common disease characterized by symptoms that include: headache, fever, nausea etc. Malaria disease is caused by a pathogen called PLASMODIUM, which is a protozoan parasite. However, these plasmodium parasites are carried to induce their damage by vectors called MOSQUITOES.
Not all genus of mosquitoes carry this pathogen but specifically ANOPHELES MOSQUITOES. The female species of an Anopheles mosquito carries plasmodium when they feed (suck blood) of an infected person. They then inject it into the bloodstream of another victim they suck from.

What happens during cell differentiation?
Mutated cells are destroyed.
Cells are organized into organ systems.
Cells become specialized to perform different tasks in the body.
Cells are transformed from one type of cell to another.
Answer:cells are transformed from one type of cell to another ?
Explanation:
Muscles have a bunch of nuclei because they need to use the DNA in the nuclei to make the large number of proteins that they must contain, so that they can relax and contract. What other organelle might muscles need a larger than normal number of?
Centrioles, so that muscle cells can retain a rigid structure during times of heavy stress (for example: lifting a heavy weight).
Mitochondria, so that muscle cells can quickly respond to the need to relax and contract.
Vesicles, so that muscle cells can ensure water availability if there is unusually low availability of water.
Answer:
it's the Mitochondria
Explanation:
The other organelle that might muscle needs a larger than normal number of is mitochondria, so that muscle cells can quickly respond to the need to relax and contract. The correct option is b.
What are mitochondria?Mitochondria is a cell organelle that is present in both plant and animal cells. It is not present in prokaryotic cells, as prokaryotic cells do not contain cell organelles. Besides storing ATP, it also generates energy that is generated from glucose.
Muscle cells have mitochondria to accommodate this energy demand. These organelles, often known as the “power plants” of the cell, transform nutrients into the molecule ATP, which serves as a form of energy storage.
Therefore, the correct option is b. Mitochondria, so that muscle cells can quickly respond to the need to relax and contract.

If you are neither relaxing or contracting a specific muscle, what is happening to the amount of ATP that is available in that muscle cell?
A. It is staying the same or increasing.
B. It is decreasing rapidly.
Answer:
A. It is staying the same or increasing.
Explanation:
The body tissues and cells require energy in the form of ATP to work, grow and move. It is produced from cellular processes like ETC, cellular respiration and other metabolic processes.
The amount of ATP in the cell:
Option A. It stays the same or increases.
The function of ATP can be explained as:
Muscle contraction and relaxation requires a certain amount of energy in the form of ATP. The insufficient amount will not be able to support the relaxation or the contraction of the muscle tissues.In the condition where there is no contraction or relaxation the amount of energy will be the same or increased as it is not used in the process and remains constant.Therefore, it remains the same or increases.

a man is twice as old as his son.Five years ago the ratio of their ages was 9:4.Find the sum of their ages
Answer:
75years
Explanation:
Let the Father's age be represented by 2x
Let the Son's age be represented by x
Five years ago;
Man's age will be = 2x - 5
Son's age will be = x - 5
If the ratio of their ages five years ago was 9:4, then;
2x - 5/x-5 = 9/4
4(2x - 5) = 9(x - 5)
8x - 20 = 9x - 45
- Collect like terms
-20 + 45 = 9x - 8x
25 = x
Hence, the son's age = 25 years
If x = 25, the father's age (2x) will be 2 × 25 = 50years
The sum of their ages will be = 25years + 50years = 75years
What is the importance of cell membranes to supporting life?
Answer:
The plasma membrane, or the cell membrane, provides protection for a cell. It also provides a fixed environment inside the cell. And that membrane has several different functions. One is to transport nutrients into the cell and also to transport toxic substances out of the cell. I hope this helps you :)

Michael and Jose are studying about plate tectonics. They learned that plates usually move a few centimeters every year. They learned that the movement of heated material caused the plates to move. In which layer does the heated material move?
Answer:
Mantle layer
Explanation:
The movement of heated materials on the mantle layer of the earth helps in the movement of the tectonic plates. The earth is made up of four layers and they are the crust, the mantle, the outer core, and the inner core. The tectonic plates are always in motion which is very slow but constant.
The convection currents emanating from the mantle layer of the earth aids the movement of the tectonic plates. Natural disasters like earthquakes can result from the intense pressure emanating from the movement of the plates.

the way that genetic information is coded in DNA is-
Answer:
with bases
Explanation:
Genetic information is coded in DNA by means of four bases: two purines (adenine and guanine) and two pyrimidines (thymine and cystosine). Each adjacent sequence of three bases (a codon) determines the insertion of a specific amino acid. In RNA, uracil replaces thymine.

A cell removes a toxin it has produced through a chemical reaction. Which characteristic of living things is the cell demonstrating?
the ability to maintain homeostasis
the ability to maintain homeostasis
the ability to grow and develop
the ability to grow and develop
the ability to adapt and evolve
the ability to adapt and evolve
the ability to reproduce
Answer:
Sweating helps the human body maintain homeostasis by cooling the body when it starts to overheat so the internal temperature is kept more or less the same. When sweat evaporates from the skin, it uses up some of the excess heat energy on the skin, thus helping to keep the body cool.
According to cell theory, all living things are made of cells, and living cells come only from other living cells. Gene theory states that the characteristics of living things are controlled by genes, which are passed from parents to their offspring.
Sample answer: The concentration of oxygen in the atmosphere is maintained at 21 percent by a balance between two opposing processes: removal of oxygen from the atmosphere by most living things and addition of oxygen to the atmosphere by living things such as plants.
Sample answer: The human ability to sweat is an adaptation that helps maintain homeostasis in a hot environment by removing heat from the body when it evaporates. Like other adaptations, the ability to maintain homeostasis by sweating evolved by natural selection sometime in our evolutionary past.
a. Gene theory
b. Homeostasis
B
An adaptation is a trait that helps a living thing survive and reproduce in a given environment. Sample example. The chameleon’s ability to change color to match their background is an adaptation.
False
False
Humans began life as a single cell because we develop from a fertilized egg cell.
Gene theory states that genes are passed down from parents to their offspring. Genes determine the characteristics or traits of an organism. If these traits are particularly beneficial or adaptive, natural selection will cause the organisms with beneficial traits to produce more offspring compared to those without the beneficial traits. This results in a change in traits over time, which is called evolution.
No. Evolution is defined as a change in the characteristics of living things over time. Evolution through natural selection causes differences in the amount of offspring produced. Having offspring (or not) is, by definition, more than one generation.
Sample answer. I think that when ancestors of chameleons could change their color to match their background, they were less likely to be detected and killed by predators than those that couldn’t change their color. Therefore, the individuals that had the color matching ability were more likely to survive and reproduce than those that didn’t. This is an example of natural selection. Over time, this led to the population evolving the color changing ability, as those that didn’t have the ability died out.
