Daren has sickle-cell disease. Because of the disease, some of Daren's blood cells are long and thin instead of being disk-shape

d. Daren's father also suffers from sickle-cell disease, but his mother and two sisters do not. This is an example how A. a person can choose which genes he or she will inherit. B. cells can be influenced by genetic factors. C. cells always repair damaged genes immediately. D. a person cannot survive if even one cell becomes damaged.

Answer: B cells can be influenced by genetic factors

Explanation: Daren has sickle cell disease. Sickle cell disorder is a kind of disease that affects the hemoglobin in the red blood cells. Hemoglobin, is a molecule in red blood cells that delivers oxygen to cells throughout the body. People with Sickle cell disorder have hemoglobin molecules called hemoglobin S, which distort the shape of the red blood cells. A normal red blood cell has a disc shape but people with sickle cell like Daren have their red blood cells and distorted into a sickle, or crescent, shape

Hello. This question is incomplete. You forgot to attach the image that completes the question.

The image is attached below:

Answer:

A- Sensory Neuron

B- Spinal cord

C- Effector neuron

D - Brain

Explanation:

  1. Sensory neuron: Its main function is to allow the reception of stimuli that are transformed into nervous impulses and electrical signals, capable of realizing sensations, such as a peliscão, for example. These impulses are transmitted to the spinal cord.
  2. Spinal cord: The main function is to support the body in an upright and vertical position. It also has the function of transmitting electrical signals and nerve impulses between some parts of the body and the brain.
  3. Effector neuron: Its main function is to receive muscle stimuli capable of creating muscle contractions. These neurons are located in the spinal cord.
  4. Brain: the processing center receives all the stimuli sent by the bone marrow. Its main function, in this case, is to produce bodily responses to the stimuli it has received, producing muscle movement.

which of the following statements are true regarding active transport and facilitated diffusion (choose two answers) a) Active t
Vera_Pavlovna [14]

Answer: B and D

Explanation: We can break down why the correct answers are choices B and D by understanding why A and C are incorrect.

Option A states that active transport utilizes channel proteins, and facilitated diffusion utilizes carrier proteins. This is incorrect. Active transport involves carrier proteins, and facilitated diffusion involves channel proteins. Carrier proteins are different from channel proteins in that, while channel proteins can only facilitate the passive diffusion of ions into or out of the cell along their concentration gradient, carrier proteins can also use ATP to move ions in or out of the cell against their concentration gradient.

This brings us to why option C is also incorrect. Option C states that both processes require the input of energy in the form of ATP. While active transport requires the use of ATP to transport ions with or against their concentration gradient, facilitated diffusion does not. This is easily remembered when we consider that active transport is called *active* transport because the cell is *actively* using energy to transport ions.

Hope this helped.
