Answer:
Yes.
Explanation:
This survival of the fittest is instinct helps domestic animals live. Just because an animal is domesticated, does not mean that instincts go away. Those instincts like hunting may get suppressed, but not taking away.
Answer:
Survival of the fittest does not apply to domesticated animals. This is because these animals don't live in the wild so they don't have to run after things and kill them. Their food comes out of a tin and is provided by human beings. They don't have any predators so their lives are seldom at risk. Thus, they don't need to be fitter or more powerful than other animals in any way.
Lets take the example of pet dogs. We keep them for our support or simply because we enjoy their company. We provide them with food, shelter etc. and protect them. Since, we basically do everything for them; they need not evolve into a stronger, more powerful species.
However, in the case of stray dogs, they have to fight for their survival. They have to fight with other dogs for food and shelter. Hence, survival of the fittest will apply here as the strongest dog gets to eat.

Three types of macromolecules are mentioned in the video that are digested and ABSORBED in the small intestine. What do they all get absorbed into first?
Lacteals
Epithelial cells
Capillaries
Given what we know about the biology of the small intestine, we can confirm that the macromolecules are being absorbed into the "Epithelial cells".
The small intestine is in charge of absorbing the nutrients, which we require in order to survive and perform even the most basic metabolic processes, from the food that we ingest. In order to be able to perform this function, the cells in question have specialized epithelium which consists of Microvilli.
Microvilli can be thought of as membrane protrusions that serve to expand the surface area of the epithelial cells. This allows the cells to have a greater area through which to absorb nutrients such as the macromolecules mentioned.

A. It is synthesized discontinuously and uses 1 RNA primer.
B. It is synthesized discontinuously and uses multiple RNA primers.
C. It is synthesized continuously and uses multiple RNA primers.
D. It is synthesized continuously and uses 1 RNA primer.
The statement 'the leading strand is synthesized continuously and uses 1 RNA primer' is TRUE. It is replicated in the 3' – 5' direction.
The leading strand refers to the DNA template strand that is synthesized in the 3' – 5' direction during DNA replication.
The 3' – 5' direction that occurs during DNA replication is the direction of the replication fork.
RNA primers are short RNA sequences used for the initiation of the synthesis of DNA (DNA replication) both in the leading DNA strand and the lagging DNA strand.

A. As the number of plants increases, the amount of CO2 decreases.
B. High clouds have a high albedo and reflect solar energy back into
space.
C. As climate warms, CO2 increases because plants remove less of
it.
D. High precipitation results in increased plant growth, lowering CO2.
A positive feedback loop that affects climate is change as the number of plants increases, the amount of CO2 decreases.
The more trees the less CO2?Scientists agree that one of the most effective ways to absorb part of the CO2 from the atmosphere would be to plant more trees, as they use CO2 to grow and release oxygen, this action brings benefits to the entire environment.
With this information, we can conclude that A positive feedback loop that affects climate is change as the number of plants increases, the amount of CO2 decreases.

Objects are brought into focus on the retina by changes in the curvature and thickness of the lens.
What is eye lens?The lens basically directs light rays onto the retina. The lens is clear and replaceable if necessary. As we age, our lenses deteriorate, necessitating the use of reading glasses.
The lens is normally clear and is located behind the iris. The pupil directs light to the lens.
Small muscles attached to the lens can cause the lens to change shape, allowing the eyes to focus on objects that are close or far away.
Light bends (refracts) and focuses on the retina at the back of the eye as it passes through the lens.
The lens's thickness and curvature can be adjusted to focus on objects at various distances and ensure that the image is as clear as possible (this process is known as accommodation).
Thus, eye lens helps to focus the object.
