Answer:
There are four principles at work in evolution—variation, inheritance, selection and time. These are considered the components of the evolutionary mechanism of natural selection.
Have a nice day!!
Energy travels through a food chain/web. When an organism eats another organism, the energy from the food is passed to the eater. For example, we humans eat food to give ourselves enough calories (energy) to function properly.
Answer:
most eukaryotic cells that are not involved in the production of gametes undergo mitosis. These cells, known as somatic cells, are important to the survival of eukaryotic organisms, and it is essential that somatic parent and daughter cells do not vary from one another.
Explanation:
The identification of an individual by the means of genetic engineering is possible because the Y chromosomes in the males does not experience any crossing-over as there is only a single Y chromosome present in a human male.
The mitochondrial DNA is passed from the mother to child in the cytoplasm of the cell, and it is passed on without any changes. The X chromosome is can be passed from a mother to her son as he will receive Y chromosome from his father.
Hence, the correct answer is 'Option B - The Y chromosome does not experience crossing over'.
Answer:
The correct answer will be option-Cell wall material is deposited to separate the daughter cells.
Explanation:
The process of binary fission divides the bacterial cell into two daughter cells with the same genetic material. The process of cell division completes only after the process of cytokinesis completes.
In both bacteria and the plants, the division of cell completes after the formation of the cell wall around the plasma membrane of the cell as cell wall forms the outer part of the membrane.
Thus, the formation of a cell wall around the plasma membrane to separate the cell is the correct answer.
