Assuming that other factors are equal, how are the birthrate and death rate

Biology

Answer:

In a stable population, if all the other factors are equal then the birth rate should be equal to the death rate in order to maintain the stability.

Explanation:

The birth rate is described as the number of births taking place in an area per year. Death rate is described as the number of deaths taking place in an area in a year.

In order to maintain a stable population, the birth rate should be equal to the death rate. If there are more number of births than the number of deaths, then it would mean more competition for resources like food, water etc.

How is cancer related to mutations? How is it related to the cell cycle?

avanturin [10]

Answer:

Cancer is related to the cell cycle bc, cancer cells mutate. Cancer is unchecked cell growth. Mutations in genes can cause cancer by making cell division rates go up faster or inhibiting normal controls on the system, such as cell cycle arrest or programmed cell death. As a mass of cancerous cells grows, it can develop into a tumor

Explanation:

hope this helps, good luck!! :)

What three processes lead to variation among offspring that have the same two parents?

beks73 [17]

Explanation:

Genetic variation in offspring during sexual reproduction is caused by

crossing over
independent assortment
randomized fertilization

Further Explanation:

All the genetic information within the eukaryotic cell is stored within the nucleus as helical DNA. This DNA is tightly wound around histones as chromosomes. To produce daughter cells during cell division, the chromosomes (total number of chromosomes (2n)) are copied before the cell splits into two daughter cells. This process is known as mitosis, and occurs in cell division and growth processes. Two new nuclei are formed, along with identical cells. These are the same as the parent cell and the chromosome number (2n) is maintained.

Conversely in meiosis, the number of chromosomes (2n) is halved through meiotic divisions, producing 4 (n) germ cells (sperm or eggs), each containing half the number of chromosomes as its parent cell.

crossing over: the exchange of segments of chromosome, between non-sister homologous or similar chromatids crossing over happens at chiasmata, the point where non-sister chromosomes are joined.
independent assortment in metaphase I of meiosis: chromosomes align independently and genes segregate independently into new combinations ...in humans 2n, n = 23, 8 million combinations of chromosomes possible
randomized fertilization: sperm cells fertilize an ovum to form a zygote. This occurs randomly by chance, to result in a complete set of chromosomes 2n, that is a novel combination of half each parent's number of chromosomes
