Active transport requires energy to move particles across the plasma membrane. Therefore, the correct option is A.
What is Active transport?A type of cellular transport known as active transport uses energy to push molecules or ions across their concentration gradient (from an area of low concentration to an area of high concentration) across the plasma membrane. It is powered by cellular energy, which is usually present in the form of ATP (adenosine triphosphate).
Because it enables the cell to move important molecules against their concentration gradient and maintains the constancy of the cell's internal environment, this mechanism is essential for preserving homeostasis in the cell. Active transport requires energy to move particles across the plasma membrane.
Therefore, the correct option is A.

A scientst wants to analyze signals from outer that ell her about the age of the universe. Her lab is equipped with advance sensors that detect sound waves and radio waves, and sesmic waves. Which of these senors will provide the best information
The correct answer is "Radio Waves."
The sensors that will provide the best information would be Radio waves.
If the scientist wants to analyze signals from outer that tell her about the age of the universe, the best equipment to do so is Radio waves.
A scientist named Karl Jansky was the first to use radio waves. Today, radio waves help scientists and astronomers to find photons with lesser energy that many times come from the farthest places of the Universe. Current modern telescopes do not have the capacity to see these parts of the Universe and radio waves allow the scientific community to get observe these distant and cold places to do advanced research.

Ok so there is four letters, 3D and 1d. The dominant allele for dark-colored hair is represented as the capital letter D. The recessive allele for light-colored hair is represented as the lowercase letter d. Think of each D and d as 25% so D+D+D= 75% and that leaves the 1d as 25%.

The identification of the process that is shown at point Z is to be considered as the option a. Translation.
What is Translation?It is the process where the ribosomes should be in the cytoplasm or the protein should be synthesize after the transcription process of DNA to RNA for the nucleus in the cell.
The overall process is known as the gene expression.
Also, the mRNA is converted into protein via the process where codons code for the amino acids.
hence, the option a is correct.

Explanation:
Most bacteria have an optimal surface area-to-volume ratio (SA/V) that balances growth, available nutrients, and cellular components. A sphere-shaped bacterium and a rod-shaped bacterium have the same volume, but the surface area of the sphere-shaped bacterium is 4.6 µm2 and that of the rod-shaped bacterium is 0.8 µm2.
Which statement compares the nutrient diffusion of the bacteria?
-It will be the same in the sphere-shaped and rod-shaped bacteria since both have similar SA/V ratios.
-It will be slower in the sphere-shaped bacterium since it has a higher SA/V ratio.
-It will be faster in the sphere-shaped bacterium since it has a higher SA/V ratio.
-It will be faster in the sphere-shaped bacterium since it has a lower SA/V ratio.
Answer:
C. It will be faster in sphere shaped bacterium as it has more SA/V ratio.
Explanation:
EDGE 2020 AP BIO
The correct answer is: It will be faster in the sphere-shaped bacterium since it has a higher SA/V ratio. The surface area-to-volume ratio (SA/V) of a bacterium is important for its nutrient diffusion.
What is SA/V ratio ?The SA/V ratio is the ratio of the surface area of a cell to its volume. A higher SA/V ratio means that the cell has a larger surface area relative to its volume and therefore more area for nutrient diffusion.
In this case, the sphere-shaped bacterium has a higher SA/V ratio than the rod-shaped bacterium (4.6 µm2 vs 0.8 µm2). This means that the sphere-shaped bacterium will have a greater surface area for nutrient diffusion, resulting in faster nutrient diffusion than the rod-shaped bacterium.
The SA/V ratio is also important for a cell's growth and metabolism. Cells with higher SA/V ratios can grow faster than those with lower SA/V ratios since they have more surface area for nutrient diffusion.
This means that the sphere-shaped bacterium will be able to grow and metabolize faster than the rod-shaped bacterium.

describe the effect on a cell wall when a vacuole fills with water
Answer:
When water moves into a plant cell, the vacuole gets bigger, pushing the cell membrane against the cell wall. The force of this increases the turgor pressure within the cell making it firm or turgid . The pressure created by the cell wall stops too much water entering and prevents cell lysis.
