Answer:
Ecology.
Explanation:
It's the study of the interaction between organisms with eachother and their environment.
Convection occurs in water so I'll say its conduction
There are omnivores, carnivores, herbivores, and decomposes. Omnivores eat both plants and animals, carnivores eat animals, herbivores eat plants, and decomposers feed on dead material.
Answer:
The duration that it takes for all voltage-gated Na+ channels to return to a closed, but active (not inactivated) state after the initial rapid depolarization "spike". ( D )
Explanation:
The property of a neuron's action potential that determines the maximum firing rate is ; The duration that it takes for all voltage-gated Na+ channels to return to a closed, but active (not inactivated) state after the initial rapid depolarization "spike".
The firing rate of a neuron defines the number of spikes that a neuron can produce per second and for a typical neuron that number is from 1 spike to 200 spikes per second
<h2>
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.
