What is the relationship between cell division and growth?

Biology
1 answer:
dimulka [17.4K]3 years ago

Answer:

The relationship between cell division and cell growth is that cell division needs to occur for the cells to divide and grow individually.

Explanation:

cell division refers to the process by which the mother cells divides into two daughter cells and cell growth refers to the process by which the size of the cell increases as it grows. They are two different but important and interlinked processes in the cell cycle. They depend on each other as failure in one will lead to failure in the other process too. The cell needs to grow proper in order to divide and create more cells.

Oduvanchick [21]

The provided question is incomplete as it lacks the combinations of parent as metion in the question, however the complete question is attached as the image.

Answer:

There are two parent combinations that are :

1. heterozygous black Ff cross with heterozygous black Ff

2. heterozygous black Ff cross with white ff

Explanation:

1. in first combination the each parent will produce F and f gametes, as it is shown as Capital F so it will be dominant over f as per the rule. so the cross can be shown as :

    F      f

F  FF    Ff

f  Ff     ff

where, FF are black Ff black and ff white offspring. As there is clearly 3 black offspring over one white spring so the ratio is 3:1 or 75% chances of black and 25% chances of white offspring (phenotype).

2. in second combination there would be F and f gametes for black parent and f and f for white parent, thus the offsprig would be :

    F     f

f   Ff    ff

f   Ff    ff

As, there is two black and two white springs are produced than the ratio would be 2:2 or 50% chances of each white offspring and black offspring (phenotype)

Which of the following is NOT a source of genetic variation?
nikklg [1K]

Answer:

The correct answer is option d) age of either or both parents.

Explanation:

Genetic variation is the difference in nucleotide sequences between individuals organisms within a particular population. Variation can occur either in germ cells that are sperm and egg or in somatic cells or in both.

Random fertilization of egg and sperm can lead to genetic variation is every germ cell has a different set of chromosomes. Independent assortment of chromosomes is also the same as random fertilization as it is also random. Crossing over of homologous chromosomes is one of a major source of the genetic variation as it forms a new set of chromosomes.

Thus, the correct answer is option D) age of either or both parents.

RoseWind [281]

Answer:

148

Explanation:

According to Hardy-Weinberg equilibrium,

p + q = 1

p² + 2pq + q² = 1 where,

p = frequency of dominant allele

q = frequency of recessive allele

p² = frequency of homozygous dominant genotype

2pq = frequency of heterozygous genotype

q² = frequency of homozygous recessive genotype

Here,

Total population = 592

Number of NN people = 148

Frequency of N blood group or NN genotype (q²) = 148/592 = 0.25

q = √0.25 = 0.5

p = 1 - q

= 1 - 0.5 = 0.5

Hence, p = 0.5

Frequency of MM genotype = p² = 0.25

Number of people with MM genotype = 0.25*592 = 148

Hence, 148 people will have MM genotype or M blood group.
