Answer:

<u>Villus- </u>It is a worm like processes on certain membranes, especially on the mucous membrane of the small intestine, where they serve in absorbing nutriment.

<u>Capillary-</u>Any of the fine branching blood vessels that form a network between the arterioles and venules.

<u>Alveolus- </u>These tiny, balloon-shaped air sacs sit at the very end of the respiratory tree and are arranged in clusters throughout the lungs.function it is to exchange oxygen and carbon dioxide molecules to and from the bloodstream.

<em>Now, they are all present at a very basic level and some how there are similarities between there nature of operations.</em>

Explanation:

  • Both alveoli and villi help in increasing surface area of the respective organ.   As they increase the region of operations for the respective organ, on which they are present on.
  • As both alveolus and villus  are associated with extensive blood capillary network for diffusion of important substances into blood: namely oxygen and dietary nutrients.
  • And the most important thing all of them are present on a minute level of the bodily operations.

Which of the following locations will be relatively warmer during summers, and why? An inland location, because water heats up f
Katen [24]

Answer:

An inland location, because land has lower specific heat than water

Explanation:

The specific heat is a measure of how much heat must be supplied to warm up a substance by a certain number of degrees.

Water has a much higher specific heat than land, so it takes much more heat energy to heat up a given mass of water compared to the land.

To say it another way, the specific heat of land is much less than that of water, so it doesn't take as much heat energy to warm up the land.

Thus, an inland location will be relatively warmer during summers.

Some species that appear to be very different from other species can actually have similar anatomy. For example the scientist be

Following are some examples of homologous structures.
A dolphin's flipper, bird's wing, cat's leg, and the human arm are considered homologous structures. Whereas human beings have bones such as the humerus, ulna, radius, wrist bones, and fingers, these features appear as similar bones in form in the other animals. Bats, whales, and many other animals have very similar homologous structures, demonstrating that these creatures all had a common ancestor.
The tailbone in human beings is so-named because it is a homologous structure to the beginning of many animals' tails, such as monkeys. It is known as "vestigial" because it is the last vestige of what was once a tail.
All mollusks have a "foot" that they use to travel. This foot is homologous although it may not appear to be immediately - close inspection demonstrates that in terms of form and function, gastropods, cephalopods, and bivalves share this homologous structure in common.
Mammals share the homologous structure of the vertebrae in common. For instance, in spite of its height, the giraffe has the very same number of neck bones (seven) as a giant whale and a tiny human being.
Human beings, dogs, and cats all have similar pelvises, which are homologous structures to a vestigial pair of bones that snakes have. These bones are the last remains of a pelvis, with no legs to attach.
Our eyes are homologous to the eye bulbs which blind creatures who live in caves have on their heads.
All organisms contain homologous plasma membranes with what is called a phospholipid bi-layer.
The wrist bone of the human being is homologous with the structures of many other animals, including the dolphin and the bird. A homologous structure in the panda looks like a sixth appendage, but it is actually a modified wrist bone that helps the panda bears pick leaves off the trees more dexterously.
An auditory bone that exists inside the ear of mammals is a homologous structure to the reptile's jaw bone (including the dinosaurs) as well as the jawbone of species of fish that are still in existence today.
The carpals, metacarpals, and phalanges of the human hand have homologous structures in a variety of animals, and they're not all mammals. For instance, these features are seen in penguins and reptiles as well as the mammals to which human beings are more closely related.
The genetic code among all living things is homologous - extremely similar although other genetic codes exist. This suggests a common ancestor.
Wasps and bees have stingers that they can use when they feel they are in danger. However, this is a homologous structure to the ovipositor of other organisms - the feature that allows these organisms to lay eggs.

Why are amphibians slimy
Aleksandr-060686 [28]

Some frogs are slimy because they are covered in a mucous coating. This coating helps them keep their skin moist which helps them breathe through their skin. The mucous often contains other chemicals, like antibacterial or anti fungals to help protect the frog.

I hope this helps you
