The correct answer is option D
The population of rabbit over the first unit of time is reduced because the population of snakes was more than the normal population.
The predators of rabbits are snakes and if the population of predator will be more than the population of the rabbit then snakes will eat them. Ultimately the population of rabbit will be decreased.
Then after some time the population of rabbit increased as the population of snakes decreased.
Answer: half the offspring will be male andvonly males will have white eyes
Explanation:
White eyed female XrXr
red eyed male XRY
crosses XrXR, XrY
half the offspring, the males, will have white eyes
Answer:
They are opened either by the binding of ligands or by changes in electric potential across the membrane
Explanation:
Ion channels are the integral membrane proteins that form pores or holes for the transport of specific ions, such as potassium ions (K+), Na+, etc. Most ion channels are selective and allow only a single type of ion to pass through. These ion channels facilitate the diffusion of ions down the concentration gradient and do not require ATP.
Ion channels are mostly gated. Some ion channels open in response to change in the concentration of ions and electric charges across the membrane. Some ion channels open and close in response to the binding of specific molecules called a ligand. For example, binding of two molecules of acetylcholine to the receptor on the motor endplate of a neuromuscular junction opens an ion channel in the ACh receptor through which Na+ can flow across the membrane.
The graph shows the ages of the women who have breast cancer, which range from ages 40 to 50. So it shows that this type of disease is most commonly diagnosed in women of these ages. Apparently, women are more prone to getting breast cancer the older they are. This is because as you get older, you lose some of your strength to fight these carcinomas so the risk of mutation grows higher as well.
Hope this helps!

Answer:</h2>
I believe the correct answer is FALSE.
<h2>
Explanation:</h2>
Innate immunity is a fast acting response to confront a pathogen but does not keep memory. It is initiated and carried out by cell and can be refered to as cellular immunity lasting for a short term.
<h2>Further Explanation:</h2><h3>Innate Immunity:</h3>
This is the first line of defence and involves only cells. It lasts for a short period usually around 12 hours. It includes physical barries. The cells involved are: epithelial cells, dendritic cells, plasma proteins and natural killer cells. All the cells involved are macrocytes. It functions to recognize and attack the pathogen before the second type of immunity called adaptive immunity sets in. It usually is also non specific and responds generally to any pathogen.
<h3>Adaptive Immunity:</h3>
It is a much more longer lasting type of immunities and has memory. It has a combination of cells and humoral components. It involves Naive B cells which are triggered to release antibodies known as Immunoglobulins depending on the cause of the trigger. Immunoglobulins include IgG, IgM, IgA, IgG and IgD and are usually Y-shaped. Additionally, it involves Naive T cells that are activated into Effector T-cells to assist in fighting the pathogen. This type of immunity is more focused and specific antibodies are released for specific infections/pathogens. It lasts up to 5 days or longer depending on the pathogen. It also takes time to mount up and produce a response.
