Why a cell spends the majority of its time in interphase.

Answers

Answer 1

A cell spends the majority of its time in interphase because during this period the cell grows and synthesizes materials required during and after its division. During interphase, the cell duplicates its genetic material.

The cell cycle can be divided into a long interphase and a short mitotic (M) phase.

The interphase can in turn be divided into three phases: Growth 1 (G1) phase,  Synthesis (S) phase and Growth 2 (G2) phase.

During the S phase, the cell duplicates its genetic material, which is sharply controlled by different cellular mechanisms (e.g., checkpoint mechanisms).

During G1 and G2 phases,  the cell synthesizes all the proteins required during the M phase and after cell division.

Which THREE statements describe how the models of mitosis and meiosis demonstrate genetic continuity?


Chromosomes are divided up evenly during Anaphase (Anaphase I of meiosis), ensuring that the daughter cells will have the correct number to reproduce.


In Interphase the chromosomes have duplicated, indicating that there will be enough genetic material to separate into daughter cells capable of reproduction.


In Prophase (Prophase I and II of meiosis) the spindles form, indicating that the chromosomes will be split evenly, and the daughter cells will receive the appropriate amount of genetic material.


In Metaphase (Metaphase II of meiosis) the chromosomes are lined up properly, indicating that the chromatids will separate evenly and provide the daughter cells with equal amounts of genetic material.


In Telophase (Telophase II of meiosis) the amount of chromatin present is equal to the amount present during Interphase, indicating that the daughter cells will receive the same amount of genetic material as the parent cell.

Answers

Answers: A,B,D

Explanation: :I took the test and got this question right .

The three statements that describes how the models of mitosis and meiosis demonstrate genetic continuity are listed and explain below.

In Anaphase, chromosomes line up in the middle of the cell while the spindle fibres pulls them apart.

Therefore the statement below about anaphase is correct.

Chromosomes are divided up evenly during Anaphase (Anaphase I of meiosis), ensuring that the daughter cells will have the correct number to reproduce.

In interphase, the synthesis of DNA occurs where the chromosomes replicates forming two identical copies of DNA.

That is, the cell now has 92 chromosomes which is enough DNA for two cells.

Therefore the statement below about interphase is correct.

In Interphase the chromosomes have duplicated, indicating that there will be enough genetic material to separate into daughter cells capable of reproduction.

In the prophase, the mitotic apparatus appears; this consists of two centrioles separated by the mitotic spindle which is formed from microtubules.

The formation of these mitotic spindle fibres indicates that the chromosomes will be split evenly.

Therefore the statement below about prophase is correct.

In Prophase (Prophase I and II of meiosis) the spindles form, indicating that the chromosomes will be split evenly, and the daughter cells will receive the appropriate amount of genetic material.

Human cells have 46 chromosomes. Each chromosome consists of a pair of identical chromatids attached together by a structure called a centromere. Once the chromosome has split, each chromatid is called a daughter chromosome. At the end of cytokinesis, how many daughter chromosomes will be found in each cell? Explain.

Answers

Answer:

92 daughter chromosomes.

Explanation:

There are 46 chromosomes in a normal cell and each chromosome turns into 2 daughter cells. So 46 plus 46 is 92.

Look at the table for energy used in activities. Ella does 2 hours of dancing a week, plays football for 1 hour a week, and goes swimming for 0.5 hours a week. She has a mass of 55kg. How much extra energy will she need a week in order to do these activities?

Answers

Ella requires 3905 kJ of energy to do 2 hours of dancing a week, 1 hour of football a week, and 0.5 hours of swimming a week.

Ella, with a mass of 55 kg, does a series of activities in a week.

Let's calculate how much energy she needs for each activity in total.

Dancing

Ellas does 2 hours of dancing a week, which consumes 18 kJ/kg.h.

2 h × 55 kg × 18 kJ/kg.h =  1980 kJ

Football

Ella plays 1 hour of football a week, which consumes 25 kJ/kg.h.

1 h × 55 kg × 25 kJ/kg.h =  1375 kJ

Swimming

Ella goes swimming for 0.5 hours a week, which consumes 20 kJ/kg.h.

0.5 h × 55 kg × 20 kJ/kg.h =  550 kJ

Total energy expenditure

E = 1980 kJ + 1375 kJ + 550 kJ = 3905 kJ

Ella requires 3905 kJ of energy to do 2 hours of dancing a week, 1 hour of football a week, and 0.5 hours of swimming a week.

Answers

Plant foods such as nuts, fruits and roots was discovered to make up the majority of the diet of human foragers. Hominine ancestors depended on foraging.

Hominine ancestors (i.e., before the evolution of H. sapiens), depended on foraging for millions of years.

Foraging refers to the search for wild food resources, which are provided by nature by gathering different sources (e.g., plants, small animals, birds, insects, etc).

Nuts, fruits and roots represent excellent sources of food because they contain both macronutrients (lipids, proteins and carbohydrates) and micronutrients (i.e., minerals and vitamins).
