Biology
1 answer:
slava [35]3 years ago
5 0

Answer:

<em>The correct option is B) Binary fission maintains genetic continuity because the daughter cells contain the same number of chromosomes as the parent cell.</em>

Explanation:

Genetic continuity can be described as a fact that the daughter cells have the same amount and same type of genome as the parent cell. It includes the transfer of parental traits to children.

Binary fission can be described as a process of division which bacteria divides. Two daughter cells are produced as a result of binary fission. Each daughter cell is identical to the parent cell and hence maintains genetic continuity.

bacteria culture starts with 400 bacteria and grows at a rate proportional to its size. After 4 hours, there are 9000 bacteria.
yawa3891 [41]

Answer:

A) P = P_0 e^{rt}

B) 19564

C) 5.5 or 6 hours

Explanation:

A) The formula that can be used for bacteria after "t" hours is

P = P_0 e^{rt}

Where ,

P represents the population after "t" hours

P_0 represents the initial population.

r represents the rate of growth of population

t represents the time taken by the population to grow

B) Here let us first find the rate of population growth.

9000 = 400 * e^{r*4}\\3.11 = r* 4\\r = 0.778

Thus, the population of bacteria after 5 hours

P = 400 * e^{0.778 * 5} \\P = 400* 48.91\\P =  19564\\

C)

30000 = 400 * e^{0.778 * t) \\\\4.317 = 0.778 * t\\t = 5.549\\or t= 5.5 or 6

horsena [70]

The answer is: 200kcal

Physical activities will cause the muscle to burn more calorie. A child that more physically active would need more calorie to supply the energy need of the muscle. Ryder participate in many physical activities most of the days of the week, so the physical activities would be around moderate to very active. The upper limit of calorie addition for moderately active child would be 200kcal.
