imagine a population of beetles. yellow beetles are easier for birds to see and eat. gray beetles blend into their surroundings, so they are less visible to birds than yellow beetles. as a result, gray beetles are more likely to survive and reproduce, enabling the gene for gray coloration to be passed on to the next generation. this increases the frequency of genes for gray coloration in the population.which evolutionary process does this scenario describe?

Answers

Answer 1

The process that describes the course of the evolutionary process is natural selection. The methods that alter allele frequencies throughout time include natural selection, genetic drift, and gene flow.

What connection does gene frequency have to evolution?

Sewell Wright's synthetic theory of evolution is an effort to explain evolution in terms of variations in gene frequencies. According to this hypothesis, a species evolves when its gene frequencies vary and it advances to a greater level of adaptability for a particular ecological niche.

What are the four evolutionary processes?

The four main driving forces of evolution are mutation, natural selection, genetic drift, gene flow, and gene flow. New genetic variety is produced via mutation in the gene pool. Allele frequencies in a gene pool are changed via genetic drift and gene flow.

What is reflex arc?

A reflex arc is a neural pathway that mediates a reflex action. It is a rapid and automatic response to a specific stimulus that does not require conscious thought or decision-making from the brain. When a sensory receptor in the body, such as the skin or muscles, is stimulated, a nerve impulse is transmitted to the spinal cord, where it is processed by an interneuron.

The interneuron then sends a signal through a motor neuron to the effector, such as a muscle, causing a rapid and involuntary response, such as pulling your hand away from a hot stove. This entire process occurs without conscious control from the brain, allowing for quick and protective responses to potentially harmful stimuli.

Which answer best identifies the difference between the two types of cellular transport? (B.4B) Question 3 options: Active transport uses ATP to move molecules against the concentration gradient. Facilitated diffusion uses ATP to move molecules down the concentration gradient. Diffusion move molecules through the cell membrane from an area of low to high concentration. Active transport uses ATP to move molecules against the concentration gradient. Active transport uses ATP to move molecules against the concentration gradient. Facilitated diffusion does not need ATP, but uses protein channels to move molecules down the concentration gradient. Facilitated diffusion does not need ATP, but uses protein channels to move molecules down the concentration gradient. Active transport uses ATP to move molecules down the concentration gradient.

Answers

Answer:

Active transport uses ATP to move molecules against the concentration gradient.Facilitated diffusion does not need ATP, but uses protein channels to move molecules down the concentration gradient

Explanation:

Transmembrane proteins, among others, are the channel proteins and the carrier proteins, and they are in charge of substances transport into or out of the cell.

Channel proteins are involved in passive transport, and facilitated diffusion is a kind of passive transport. Facilitated diffusion transport hydrophilic molecules that can not freely move through the membrane. Channel proteins carry them from one side to the other of the membrane, following the electrochemical gradient, so they do not need energy to carry in or out substances. Uncharged molecules´ movement depends on concentration gradients, while ions´ movement depends on an electrochemical gradient.Carrier proteins are involved in active transport. Active transport acts against the electrochemical gradient, so it does need the energy to transport substances. It carries molecules from a low concentration side to a high concentration side. The used energy comes from ATP (Na-K bomb) or the membrane´s electric potential.
