Answer:
When a red blood cell is placed in a hypertonic solution, it contracts as water is drawn out of the cell and into the surrounding solution. If the same blood cell is placed in a hypotonic solution, the blood cell grows in size. Blood cells in isotonic solutions do not shrink or swell.
The reason that blood cells change in size when placed in a solution with different salt concentration is due to the osmosis process. Osmosis causes solutions with high concentrations of salt to draw water from areas with low concentrations of salt.
There are some exceptions to this phenomenon. Blood cells can draw water and explode when placed in hypertonic solution on some special occasions. Some diseases affect the structural integrity of blood cells. Also, when human blood cells are exposed to temperatures close to freezing, they can draw water and explode.
Osmosis is an important phenomenon for living systems. The amount of salt in a given solution exhibits a tendency to diffuse through the environment, eventually resulting in equilibrium. In addition to blood cells, the kidneys function through the use of osmotic principles. The kidneys filter an animal's blood to remove excess salt and balance the amount of water
<span>D. evidence that are acquired through use or disuse. Since it is believed that some parts of an organism developed through its need. For example a giraffe got its long neck becuase of reaching for a tree that could produce its food. Another example is the leg of a human which developed because of its need to walk. It was believed that the parts of the an organism did exist or did vanish depending if it was no longer used or it was necessarily needed to survive.</span>
The reason for the change in the hands of the chimpanzee include:
- Crossbreeding between gorillas and chimpanzees( Represents a reason for the change)
- Mutations in chimpanzee DNA ( Represents a reason for the change)
- Differences in the ways chimpanzees use their hands ( Doesn't represents a reason for the change)
- Sexual reproduction ( Doesn't represents a reason for the change)
- Differences in enhancer sequences( Represents a reason for the change).
<h3>What is mutation?</h3>
Mutation is defined as the alteration in the genetic makeup of a living organism which may occur due to the following:
- When there is spontaneous break down of deoxyribonucleic acid (DNA).
- Change in a single nucleotide of the DNA.
- when there is additions or deletions of nucleotide in a DNA strand.
A change can be noticed in an animal such as Chimpanzee when the following occurs:
Mutations in chimpanzee DNA: This can alter both that anatomy and the physiological features of the organism involved.
Crossbreeding between gorillas and chimpanzees: When there is cross breeding between a chimpanzee and a gorilla, it will lead to a genetic diversity which can be observed as a change in the hands of the chimpanzee.

Answer: D) The lizard and the snake are secondary consumers.
Explanation:
Producers are organisms that, simply put, produce their own food. All photosynthesizing plants are considered to be producers. Animals cannot be producers.
Primary consumers eat producers.
Secondary consumers eat primary consumers.
Tertiary consumers eat secondary consumers, and so on.
The lizard eats a fly, which is a primary consumer. This makes the lizard a secondary consumer.
The snake eats a mouse, which is a primary consumer. This makes the snake a secondary consumer.
A) is incorrect because the hawk is a tertiary consumer.
B) is incorrect because grass is a producer, not a consumer
C) is incorrect because the lizard is a secondary consumer
Answer:
No
Explanation: its related to climate
