Answer:
The three statements or tenets of the cell theory are: All living beings are made up of cells. Cell is the most basic unit of life. All cells must come from pre-existing cells.
Explanation:
Answer:
After the flood the total number of beetles = number of beetles per hectare × 115 hectares = 8,855 beetles.
The carrying capacity is 14,600 beetles.

Answer:
D. A population with high genetic biodiversity is better able to respond to environmental stressors.
Explanation:
The genetic biodiversity of a species is the diversity of alleles that it possesses in its genetic pool. For a given gene, a population can have one or more alleles; and the more alleles the population has, it will be more diverse. Under normal conditions (without stress), the alleles that are present in high frequency in a population, are those that best respond to the environment where the population occurs. However, if some environmental condition changes and some type of environmental stress emerge (ie drought), it is possible that these alleles no longer respond equally effectively and then, it is possible that the alleles that on normal conditions occur with low frequency, are more adequate to face the stress. A population with fewer alleles (less genetic diversity) has terefore fewer options to deal with environmental stressors and<u> a population with high genetic biodiversity</u> will do this better.
Protostomes develop a mouth first and then an anus. This is the difference between protostomes and deuterostomes.
In protostome development, there is a spiral radical and indeterminate cleavage. The blastopore becomes the mouth and the coelom forms from the mesoderm.
In deuterostomes development, radial and indeterminate cleavage takes place. The blastopore is the new anus and the coelom forms from budding off the wall of the archenteron.
Answer:
<em>The process of </em><u><em>exocytosis </em></u><em>could be responsible for its secretion. </em>
Explanation:
Exocytosis can be described as a process in which molecules are transported out of a cell in vesicles. The process of exocytosis usually requires energy as molecules are moved out of a cell by the method of active transport.
As certain cells that line the stomach secrete a protein and release it into the stomach we can infer that the process is exocytosis. Peptides, hormones and various antibodies are also transported to different locations through the process of exocytosis.
