Answer:
Evolution
Explanation:
Evolution – change over time. It is the process by which modern organisms have descended from ancient organisms. Current scientific facts, observations and hypotheses all combine to create current evolutionary theory – which is a well-supported, testable explanation of the biological diversity on Earth.
Answer:
The surface area of the cell increases to volume ratio
Explanation:
As a cell grows, the surface area of the cell increases to volume ratio. When cell division occurs, the surface area is distributed and each daughter cell have less surface area but with the passage of time, the surface area increases. The main function of mitosis is to increase the population of the cell, the cell must be divided into two daughter cells in the process of mitosis. Tumors occurs when the process of mitosis is uncontrollable. One observation that is found interesting while looking at the onion root tip cells is the multiplication of the cells by the process of mitosis.
The answer to this question may be the second one," Mitosis produces two genetically identical daughter cells but meiosis produces four genetically different daughter cells."
Complete question:
A geneticist crossed pure breeding black mice with pure breeding brown mice. All the 992 mice in F1 generation had black coats. When these mice were crossed, the yielded 961 black coated mice and 317 brown coated mice. How could you account for the ratio of black coated to brown coated mice in the F2 generation? Select all that apply
- The F1 male produced two kinds of sperm, half carrying an allele for black coat color, and half carrying an allele for brown coat color.
- The brown allele segregates together with the black allele and disappears in the F1 generation.
- The F1 female produced two kinds of eggs, half carrying an allele for black coat color, and half carrying an allele for brown coat color.
- An approximately three-to-one ratio of black to brown coated mice in the F2 generation is accounted for by the black allele being dominant over the brown allele.
Answer:
- The F1 male produced two kinds of sperm, half carrying an allele for black coat color, and half carrying an allele for brown coat color. APPLIES
