<span>Protein is the nutrient that provides 4 calories per gram and helps to build/maintain tissue structures. This is the correct answer because both vitamins and minerals have 0 calories per gram. Additionally, while carbohydrates do have 4 calories per gram, this is the incorrect answer because they do help build tissues and instead function primarily as an energy source for the body.</span>
Answer:
1. The goal of mitosis is to produce daughter cells that are genetically identical to their mothers, with not a single chromosome more or less. Meiosis, on the other hand, is used for just one purpose in the human body: the production of gametes—sex cells, or sperm and eggs.
2. Cell division is needed to produce large number of cells necessary to form the individual. ... DNA replicates before a cell divides to give a complete set of genetic instructions to each daughter cell.
3. Cancer cells differ from normal cells in many ways that allow them to grow out of control and become invasive. One important difference is that cancer cells are less specialized than normal cells. That is, whereas normal cells mature into very distinct cell types with specific functions, cancer cells do not.
4. okay I think this is right if not then sorry
Other mistakes that can occur during meiosis include translocation, in which part of one chromosome becomes attached to another, and deletion, in which part of one chromosome is lost entirely.
Yes this is correct well done
Daniel Nathans and Hamilton Smith who discover the Impermanence of Sexual Phenotypes as to the absolute statement.
Phenotypic sex is refer to an individual's sex as intent by their internal genitalia, expression of secondary sex attribute, and behavior.
Answer:
The correct answer is - Development of simple bacteria→RNA formation→DNA formation
Explanation:
According to the hypothesis and researchers, it seems to confirm that RNA was the first genetic or hereditary material that was present in the simple form of bacteria developed first.
RNA is the molecule responsible for the origin of life on the earth and evolved all the required processes and methods for carrying and expressing the genetic information of an organism before DNA. DNA is evolved from RNA molecules of simple bacteria.
