andreyandreev [35.5K]

Answer:

Please find the similarities and differences between these cells below.

Explanation:

According to this question, six specific cells are examined. They are: neuron, red blood cell, osteocyte, skeletal muscle cell, sperm cell, and egg cell.

SIMILARITIES:

These cells are cells that make up different tissues and systems in living organisms. They perform different functions in their respective locations, however, they are similar in the sense that they all possess some cellular components called organelles. The organelles that are common to all these types of cells are CELL MEMBRANE, RIBOSOMES, MITOCHONDRIA, GENETIC MATERIAL (DNA), NUCLEUS,

They also possess two set of chromosomes in their nucleus i.e. diploid.

DIFFERENCES:

However, they differ in their functions. For example;

- neuron: nerve cell whose function is related to the nervous system

- red blood cell: blood cell whose function is related to circulatory system

- osteocyte: bone cell whose function is related to the skeletal system

- skeletal muscle cell- muscle cell whose function is related to the muscular system

- sperm cell: a male sex cell whose function is related to reproduction

- egg cell: a female sex cell whose function is related to reproduction

A biologist marked 200 mice, by putting leg bands on them, out of a forest containing an unknown number of mice. The marked mice

Fofino [41]

Answer: The estimated population is 1250 mice

Explanation: The method use was marked and recapture, in which individuals are marked in the first capture and after some time biologist trap a new group of individuals that can be or not marked

Whit this data is possible to estimate the size of a population applying the Peterson method but is important to make some considerations such as:

1. All indivuals have the same probability to be capture

2, The population remain constant in terms of birth and death rate.

Taking this into account, the formula that allows to determine the size of the population is:

N=CM / R

where N is the size of the population, C is number of indivuals trapped in recapture, M is number of individuals marked in the first capture and R is the number of marked animals trapped in recapture

In this case:

N = 250 * 200 / 40 = 1250

In the presence of oxygen, all cells synthesize ATP via the process of glycolysis. Many cells also can metabolize pyruvate if ox

Slav-nsk [51]

Answer:The option are not given, here are the options gotten from another website.

A. Aerobic respiration

B. Electron Transport Chain

C. Anaerobic respiration

D. Krebs cycle

The correct option is C.

Explanation:

This is because anaerobic respiration is a type of respiration that produced ATP. pyruvate are metabolize in the absence of oxygen by a process called fermentation and fermentation us anaerobic respiration. And fermentation is the chemical process where glucose or substrates are broken down in the absence of oxygen by the activities of enzymes. When pyruvate are metabolize in the absence of oxygen , it will produce lactate.
