20. Which of the following is an example of homeostasis?A human participates in vigorous activity on a hot day and eventually suffers from dehydration.
A human body loses too much heat on a cold day, and hypothermia occurs.
A cactus stores water during wet periods, allowing it to live through dry periods.
A snake rests in the sun on a summer day, and its body temperature eventually becomes too hot for survival.

Answers

Answer 1

Answer: Well,

Homeostasis means "maintaining the status quo." That just means remaining the same.

The first, second, and fourth options, do not represent homeostasis, as something happens to the organism that is not normal.

The third example is an example of homeostasis because the cactus is preparing for the dry period, during which it can maintain the status quo because of its stored water.

Answer 2

Answer: A cactus stores water during wet periods, allowing it to live through dry periods.

What happens to a population and to competition when there is a reduction of living space?

Answers

Answer:

Competition will increase among population due to reduction of living space.

Explanation:

Competition is the type of interaction between two organisms of same or different species in which both are harmed. So when the living space will reduce more individuals will forced to live in small area fighting for same resources. In this way the competition will increase among them.

This competition can lead to the eradication of individuals which are less adaptable or mutation in their genes that allow them to flourish different niche for example Darwin's finches of Galapagos island.

if living space is reduced, then competition increases! if there's nowhere to go then there's going to be some pretty high tension!

Why do all swordfish have ‘swords’? Use the word ‘inherited’ in your answer.

Answers

All swordfish have 'swords' because it is a characteristic inherited trait from their parents.

Inherited traits are passed down from one generation to the next generation through genes. In the case of swordfish, the sword-like bill which is present is a unique adaptation that has been passed down through generations. This bill is believed to have evolved to help the swordfish in catching prey, defending themselves, and also in attracting mates.

The swordfish that had longer bills were more successful in survival and reproduction, which is the reason why this trait has been preserved and is observed in all swordfish today.The traits that are transmitted by the parent to its offspring during the process of fertilization are inherited traits. This inheritance is determined by certain rules of heredity.

Thus, all swordfish have sword as they are inherited traits.

The swordfish bill, on the other hand, is smooth and horizontally flattened, better suited perhaps for whacking larger prey like squid. Beyond their "swords," all billfish come equipped with a remarkable internal heating system for their eyes, keeping them ten to fifteen degrees Celsius warmer than ambient water temperatures.
