Answer:
b. founder effect
Explanation:
When there is a situation when sufficient number of members of one species are reproductively isolated, and if there is an evolutionary pressure for them to start developing new advantageous traits, then a new species will gradually emerge. In this kind of scenario the genetic diversity will be minimized, as the number of individuals is much smaller, and that will result in only changes that will go in only one direction and they will also occur quicker than if there was a greater genetic diversity. This is called the founder effect, and it is easy to see why this term has been chosen, as the limited number of members of a species that have been reproductively isolated are giving the foundation for the development of a new, separate species.
The correct answer is water. Since carbon
is the common element of organic compounds, the molecule of
an organic material must have at least one carbon atom in its molecule. Water does not
contain any carbon atom in its molecule, H2O. So water is only an inorganic compound. <span>It is the most abundant and important inorganic compound in
living material. It makes up about 60-80% of the volume of most living cells.</span>
<span>In mammals, air enters lungs through tubes called _____, which branch into smaller tubules called _____, which extend out to tiny air sacs called _____.
trachea; bronchioles; spongy tissue
>> bronchi; bronchioles; alveoli
bronchi; alveoli; gills </span>
I believe that most mature soils have three soil horizons. That is Horizon A, Horizon B, and Horizon C. Horizon A, also called the top soil contains a mixture of mineral matter and organic matter, as well as many insects, fungi, and microorganisms. Horizon B, also called the sub soil, contains fine clay particles washed out of horizon A. Horizon C contains partially weathered parent material.
The answer is true, Sponges can regenerate the entire organism from just a conglomeration of their cells. They can be cut up or mashed, and as long as they have two special cells called collencytes, which produce the gelatinous matrix in the sponge, and archeocytes, which produce all the other cells in the spongeâ??s body, the sponge will reform into the sponge it once was. Although, it will look different. Hope it helps!
