The movement of water across cellular membranes through aquaporins is known as osmosis. Water moves down the concentration gradient. The fourth option is the correct answer.
How do molecules move across the cell membrane?Molecules can pass the cell membrane both actively and passively. In passive transport, no energy or ATP is required. Molecules can move from a higher concentration to a lower concentration.
Diffusion and osmosis are examples of passive transports. In diffusion, gases and other small molecules pass the cell membrane from a higher to a lower concentration. Water is a polar molecule, so it doesn't pass the membrane due to its nonpolar nature. Cells have aquaporin channels that are made for water.
Through aquaporins, water passes into the cell. This is called osmosis. In active transport, energy is required. When a molecule passes from a lower concentration to a higher concentration, energy is needed. An example is sodium-potassium ATPase.
Hence, the correct answer is osmosis. The fourth option is the correct answer.

in the Fall of the year, leaves appear red, orange, yellow and brown because the chlorphyll decreases in the leaves and allows the --(blank)-- pigments to reflect mostly colors other than green.
possible answers than can go in the blank are primary or accessory
The appropriate word to fill into the blank would be accessory.
In the Fall of the year, leaves appear red, orange, yellow, and brown because the chlorophyll decreases in the leaves and allows the accessory pigments to reflect mostly colors other than green.
The core pigment in leaves that makes them appear green is chlorophyll. The pigment is primarily responsible for absorbing light energy to drive the photosynthetic process in plants.
Some other pigments, also known as accessory pigments such as carotenoids, anthocyanins, xanthophylls, etc., help out chlorophyll in some ways but have colours that are different from green.
Thus, the appearance of other colours such as orange, yellow, brown, etc., on leaves is due to a decrease in chlorophyll and the reflection of the colours of the accessory pigments.

The difference between bacterial and eukaryotic transcription is that in bacteria, transcription and translation can occur simultaneously in the cytoplasm of the cell, whereas in eukaryotes transcription occurs in the nucleus and translation occurs in the cytoplasm.
What is the difference between eukaryotes and prokaryotes?The main difference between eukaryotes and prokaryotes is that the eukaryotes are well developed and advanced and have different cell organelles and they have different functions in the cell and the prokaryotes are not well developed and they are found in the unicellular organisms.
The unicellular organisms are made of one cell and carry out the processes of life as a single cell and the multicellular organisms are made up of two or more cells that have specific functions to contribute to the life processes.
Therefore, The difference between bacterial and eukaryotic transcription is that in bacteria, transcription and translation can occur simultaneously in the cytoplasm of the cell, whereas in eukaryotes transcription occurs in the nucleus and translation occurs in the cytoplasm.

Maxine miles runs a marathon in 2 hours and 40 minutes. Most of the ATP for this activity is supplied by AEROBIC glucose breakdown. ATP is the energy coin of the cell.
Cellular respiration refers to the metabolic processes by which aerobic cells produce ATP by using the energy stored in the chemical bonds of foods (e.g., glucose) and oxygen.
Muscle cells can produce ATP by both cellular respiration (aerobic conditions) and acid lactic fermentation (anaerobic conditions).
Acid lactic fermentation is a less efficient pathway than cellular respiration, but cellular respiration is slower than fermentation, thereby muscle cells use this pathway (acid lactic fermentation) when there is not enough oxygen in the body.

Which is the most highly sensitive time within the developing embryo for the risk of malformation related to environmental teratogens
The most highly sensitive time within the developing embryo for the risk of malformation related to environmental teratogens is cleft palate at 8 weeks gestation. It is an opening in the roof of the mouth.
A teratogen is any substance and/or physical agent that may cause an irreversible abnormality in the structure of the developing embryo or fetus (e.g., classical pesticides such as DDT).
Cleft palate is a malformation mainly caused by mutagenic agents (teratogens) during pregnancy, which affects approximately one (1) of 650 births.
A cleft palate is a malformation that occurs when the two plates of the skull that form the roof of the mouth cannot be completely joined.

The choroid stains dark as it contains pigments and blood vessels. It is
located underneath the retina. It also lies between the retina and the sclera.
The choroids are very rich in connective tissues( blood vessels) which help
supply the retina with vital nutrients needed for proper eyesight.
The choroids are usually thickest at the extreme rear end of the eye and also helps to maintain a constant eye temperature and volume. This is
important to prevent changes in eye size and temperature which may cause

When is the kinetic energy of a pendulum the least?
Question 5 options:
Half the distance on the path traveling back down.
On the path beginning the upwards swing.
At the bottom of the swing.
At the top of the swing where it briefly stops before changing direction.
Answer:
The answer is D. At the top of the swing where it briefly stops before changing direction.
Explanation:
When the pendulum is either at its far right or left position, the bob is at rest and therefore its kinetic energy is equal to zero- making it the lowest point of kinetic energy during the whole process.
Answer:
The answer is C
Explanation:
because when your on the swing the most kinetic energy is where you start to go to the upwards part right when the drop happens
it allows you to swing up very high making the option C correct

S. aureus is gram positive. What differences in strains might account for differences in phage susceptibilities?
S. aureus is indeed gram-positive but within the bacteria classed as gram-positive, there are differences that might predispose them to infection by phages.
S. aureus as an organism usually adapts to their environment through mutations on their membranes which can be proteins e.g. surface proteins, or receptor molecules e.g. sugar receptors.
In preventing invasion by phages, mutations are gained that prevents attachment to the bacteria cell surface. This effectively prevents the binding of the phage to the bacteria thus preventing infection.
It is also worthy to note that the differences in bacteria strain could range from a few nucleotides to large variations in chromosomes and thus can aid in identifying specific strains that might have beneficial factors in the context of disease prevention.
