Answer:
<h2>
A
</h2>
Explanation:
1. A channel between two adjacent cells in known as an intercellular cleft.
2. And through these channels many molecules can easily pass between cells.
3. Importance of Intercellular clefts:
i) It is very important in transportation of fluids and small solutes.
ii) It contains gap junctions, tight junctions, desmosomes, and adheren proteins and these junctions help in regulate cell communication by signal transduction, surface receptors, or a chemogradient.
Answer:
When a species goes into hibernation, the heart rate drops drastically, and the body temperature does as well, in order to conserve energy. The body becomes induced into a comatose state by releasing chemicals from the brain to body to go into sleep mode.
Explanation:
Hibernation usually occurs during the winter.
Answer:
insolation
Explanation:
insolation is the incident solar radiation onto some objects
The current population of a threatened animal species is 1.6 million, but it is declining with a half-life of 25 years. How many animals will be left in 35 years<u> The decay law i</u>
<u>p(t) = 1,700,000 (1/2)t/25</u>
<u>where t is in years and p(t) is the population at time t. Plug in 40 and 55 for t.</u>
<h3>What is
threatened animal?</h3>
Any species (including those of animals, plants, and fungi) that is likely to become endangered in the near future is considered to be a threatened species. The population dynamics measure of critical depensation, a calculation of biomass related to population growth rate, is occasionally used to identify threatened species. This quantitative indicator is one way to gauge how endangered an area is. When discussing IUCN categories, the terms threatened and vulnerable may be used interchangeably; however, threatened generally refers to the three categories (critically endangered, endangered, and vulnerable), whereas vulnerable generally refers to the category that is least at risk among the three. However, since all threatened species are vulnerable species, they can usually be used interchangeably.
