<span>The hypothalamus in the brain plays a primary role in regulating body temperature. When a person is exposed to a cold environment, the hypothalamus senses such a change, causing the body to undergo changes that conserve heat (blood vessels constrict, muscle cells contract involuntarily, a process referred to as shivering). Conversely, when one is exposes to excess heat, the hypothalamus also senses such an environmental change, and triggers physiological processes such as sweating and the dilation of blood vessels.</span>
If a Caterpillar is grown in the dark, then it will be the same color as a Caterpillar when it metamorphisizes
Answer:
<u>I. Define the following terms:-</u>
Population ➝ the world population is the total number of humans currently living.
Population density ➝ is a measurement of population per unit area or volume. It is frequently applied to living organisms, most of the time to humans.
Carrying capacity➝ is the average population density or population size of a species in a habitat.
Exponential growth➝ is a process that increases quantity over time. It occurs when the instantaneous rate of change.
Density-independent limiting factor➝ is any force that affects the size of a population of living things.
Logistic Growth ➝ is a population's per capita growth rate stays the same regardless of population size, making the population grow faster as it gets larger.
Density-dependent limiting factor➝ is a limiting factor of a population wherein large, large dense populations are more affected than small, less crowded ones ex. predation, competition, food supply.
<u>II. Enumarate at least three(3) factors that affect population growth.</u>
<u>III. Differentiate exponential growth and logistic growth.</u>
Exponential growth is a growth in population wherein the number of individuals increases. Logistic growth entails exponential growth in population along with a growth rate that is in a constant state. As the population comes to its carrying capacity, the growth rate then decreases significantly.

Newtons second law of motion
Answer:
A) 5' AGCTAG 3'
Explanation:
DNA strands are antiparallel meaning that 3' to 5' has a complementary strand from 5' to 3'. This means that the last two answers can be eliminated because you can't have the 3' side pair up with a 3' side.
the other thing to remember is one of Chargaff's rules:
- A pairs with T
- G pairs with C
When writing a complementary strand's sequence, you must "convert" the letter in the original sequence to the letter that it is paired with by Chargaff's 2nd rule.
