Answer:
When comparing homologous structures, we are comparing the anatomy of one part of an organism to another and finding it to be structurally similar but functionally may be different. Let’s compare a couple of tetrapods, specifically a human arm and a cat arm.
Both the human arm and the cat arm have a single bone in the upper arm, which we call the humerus, followed by two bones in the forearm–the radius on the more medial side and the ulna on the more lateral side. Both arms also have a common wrist structure followed by a grouping of metacarpals and phalanges. All of these structures are similar; however, these structures do not have the same function. Cats are quadrupeds that use their arms for walking and maybe a little climbing and hunting for outdoor cats. Humans, on the other hand, use their arms and hands for gross motor movement like grabbing, hugging, and lifting, as well as fine motor movement like using tools or even communicating.
A whale flipper and a bat wing are also homologous structures in the same sense as a human arm and cat arm with a humerus, radius and ulna, and so on. But the whale’s “arm” is actually a flipper that it uses to swim while the bat uses its wing to fly.

lungs and capillaries both have porous linings that allow certain substances to move into or out of the structures. Which function do these porous linings most likely serve in living organisms?
A. heat release
B. gas exchange
C. carbohydrate absorption
D. osmotic pressure regulation
Answer:
B. Gas exchange
Explanation:
because the lungs bring air into your body, it needs a way to transfer the oxygen into your blood stream.
Luckily for us, our lungs have porous linings, which will help the oxygen go directly into our blood stream.
The porous structure of the blood capillaries and lung tissue allow the them to exchange gas
The porous structure of the lungs allow to exchange gas from the gas in the blood. Blood capillaries are tiny blood vessels in the body.
The gas in the blood was collected from the tissue from the body parts which is made possible because of the porous lining of the blood capillaries.
Therefore, the porous structure of the blood capillaries and lung tissue allow the them to exchange gas.

If fertilization occurs which layer does the egg burrow into
a.myometrium
b.perimetrium
c.endometium
According to the research, the correct option is c, If fertilization occurs the egg burrows into endometium.
What is endometium?It is the tissue that covers or upholsters the uterine cavity whose function is to receive the fertilized egg when pregnancy occurs, that is, it allows the implantation of a fertilized egg, which will later transform into a new being.
For the endometrium to carry out its function, it has to undergo a series of morphological and functional modifications linked to the secretion of hormones by the ovaries so that at the time of greatest receptivity, the endometrium has the thickness and the nutrients necessary for a correct interaction with the embryo.
Therefore, we can conclude that according to the research, the correct option is c, If fertilization occurs the egg burrows into endometium.

One limitation of food webs in representing an ecosystem is that they do not
A. Include producers in the ecosystem
B. Show consumer in the ecosystem
C.include all species in the ecosystem
D. Show predator prey relationships
Answer:
I think D (This isn't verified as correct, only my best concluded answer in terms of correction.)
Explanation:
The reason why I believe D is the answer is because the other answers are included in a food web. The reason for considering D is because I'm pretty sure that consumers are apart of a food web which could be logical for eliminating answer B. D would be a good answer considering that a food web consists of producerd and consumers and the transfer of energy. Relative to whether that's considered as a predator prey relationship other than an energy transfer relationship then D would probably be your answer.
One limitation of food webs in representing an ecosystem is that they do not show predator-prey relationships. So, the correct option is (D).
What is Food web?A food web is defined as the natural interconnection of food chains and is a graphical representation of what-eats in an ecological community. It is also known as a food web consumer-resource system.
A food chain is described as the direct transfer of energy between organisms, where each organism may feed on many things while the food web is a more realistic and simplified way of transferring energy in an ecosystem.
For the information above, consumers are different from a food web which may be logical where a food web consists of producers and consumers and there is a transfer of energy but in addition to the energy transfer relationship is considered as a predator prey relationship goes.
Thus, one limitation of food webs in representing an ecosystem is that they do not show predator-prey relationships. So, the correct option is (D).
