Georgia [21]3 years ago

The answer is “common ancestry”

andre [41]3 years ago
3 0

Answer:

The correct answer is option 2. Common ancestry.

Explanation:

The homologous structure is the structure that has a similar anatomical structure or underlying skeleton and can perform a different function in different organisms.

Homologous structures are similar in different organisms because they diverge from a common ancestor. All organisms that have homologous structures are considered to have a common ancestry. for example, human arm, dogs forearm, bat's wing all have a similar skeleton structure  

Thus, the correct answer is option 2. Common ancestry.

How can a change in technology affect scientific knowledge?
Shalnov [3]
It helps scientists improve on research and tests/examinations to understand the object a little more. For Example: The newer modified microscope helps zoom into harder to see microrganisms. So if technology changed then most of our scientific knowledge wouldve been mistaken this whole time. We wouldnt know many things if technology didnt exist.

What characteristic of water causes water to stick to the side of a test tube?
bazaltina [42]

Answer:

The characteristic of water that makes this liquid stick to the side of a test tube is called capillarity (Claim).

Explanation:

Water (H₂O) is a polar molecule with the ability to generate van der Waals forces, which is explained by the 4 hydrogen bonds it forms to bind to other substances. The consequence of the forces of the molecular bonds are four properties of H₂O, including surface tension, cohesion, adhesion and capillarity.

- <u>Claim</u>: The characteristic of water that makes this liquid stick to the side of a test tube is called capillarity.

- <u>Evidence</u>: Cohesion and adhesion of water are properties that come from the forces of the molecular bonds of water, and whose effect is the ability of water to wet surfaces and adhere to a tube that contains it, the latter due to capillarity. Capillarity also allows water to rise through the roots and stems of plants, through their thin vascular ducts.

- <u>Reasoning</u>: <u>cohesion</u> in water depends on the force of attraction between H₂O molecules, <u>adhesion</u> is the capacity of H₂O molecules to join other different molecules and —together with <u>surface tension</u>— make H₂O molecules close to the walls of a glass tube adhere to it, which represents capillarity.

The effect of capillarity is more evident when the test tube is of a smaller diameter, although capillarity and adhesion to its walls always exist, and to a greater degree than any other substance.

Cabbages have 18 chromosomes. How many chromosomes do each of the daughter cell produced by mitosis have?
AVprozaik [17]
This is because daughter cells are identical to the original cell.
Although during the process of mitosis the number of chromosomes changes, the final number of chromosomes in each daughter cell is always the same number as were in the original cell.
