The nucleus controls and regulates the activities of the cell (e.g., growth and metabolism) and carries the genes, structures that contain the hereditary information.
Answer:
The answer is A. a tissue
Explanation:
Tissues are groups of similar cells that have a common function. An organ is a structure that is composed of at least two or more tissue types and performs a specific set of functions for the body.
Answer:
Parapatric speciation
Explanation:
There are different types of speciation. Parapatric speciation consists of new species evolving from a continuous distribution. That is, there is no physical barrier that might impede the gene flow, in fact, it might continue during the speciation process.
There is an environmental gradient that determines different phenotypes for different environmental conditions. One phenotype is more adapted to one of the distribution extremes than the other phenotype. In the exposed case, the environmental gradient is given by the differences in pH.
In the border between the environmental extremes, there is the primary hybrid zone, where both phenotypic forms might meet and hybridize.
The correct description of alcoholic fermentation is the anaerobic pathway carried out by yeasts in which simple sugars are converted toethanol<span> and carbon dioxide</span>
Answer:
B. False
Explanation:
Meiosis is a process where a single cell divides twice to produce four cells containing half the original amount of genetic information. These cells are our sex cells – sperm in males, eggs in females.
