If there are 8 centromeres in metaphase, how many centromeres will be present in anaphase?A. 4B. 8C. 16D. 32

Answers

Answer:

B.8

Explanation:

In a dividing cell, each chromosome consists of two chromatids. Both the chromatids remain attached at the centromeres. If in a dividing cell there are 8 centromeres, indicates that dividing cell has 8 chromosomes. Chromosomes separate during anaphase. The cell is still dividing and not separated into two daughter cells. Therefore, if the cell has 8 centromeres during metaphase, the same number of centromeres will be present during anaphase. Thus, 8 is the correct answer.

Glucose is stored as which molecule within the liver and skeletal muscle tissue? a. Starch
b. Phospholipids
c. Glycogen
d. Glucagon

Answers

Answer:

C. Glycogen

Explanation:

When the food made of carbohydrates is broken in the organism, it creates glucose, which is a type of sugar that the body uses as a form of energy. The amount that is not used gets stored in various tissues of the body, but the places where the glycogen is stored in larger amounts are the liver and skeletal muscle.

Answer:

Glycogen

Explanation:

Glucose is used primarily as a source of energy and as such it has to go inside the cell. Excess glucose that is not immediately needed as a source of energy is combined into long strands of clucose units called glycogen and it is stored in the liver and skeletal muscle tissue. Glycogen is later broken dowin into its constituent glucose units and used as a source of energy when needed.

If the metabolic rate of cockroaches at 15°C is 0.01 ml O2/hr and their metabolic rate at 25°C is 0.015 ml O2/hr. What is its metabolic rate at 20°C?

Answers

Answer:

0.0035 mL of oxygen per hour is metabolic rate at 20°C at cockroach.

Explanation:

Metabolic rate of cockroaches at 15°C is 0.01 ml O2/h
Metabolic rate of cockroaches at 25°C is 0.015 ml O2/hr

From the data we can see that metabolic rate of cockroach is in direct relation with temperature.

$Rate \propto Time$

On graph, with metabolic rate on y-axis and temperature on x axis straight line will obtained , and the equation of the line can be determined by the help of point slope:

$(y-y_1)=m(x-x_1)$

m = Slope of the line = $(y_2-y_1)/(x_2-x_1)$

As per information given , :

$(x_1,y_1) , (x_2,y_2) = (15,0.01) (25,0.015)$

$m=(0.015-0.01)/(25-15)=(0.005)/(10)=0.0005$

$(y-0.01)=0.0005(x-15)$

$y-0.001=0.0005x-0.0075$

$y=0.0005x-0.0065$

x = temperature

y = metabolic rate

Now , put x = 20

$y=0.0005* 20-0.0065$

y = 0.0035

0.0035 mL of oxygen per hour is metabolic rate at 20°C at cockroach.

Transposons need to __________________ in order to limit their negative impact on the genome of the host cell. A. control their nucleotide length B. regulate their copy number C. control their target-site choice D. avoid transposing into their own genome

Answers

Answer:

The correct answer is B

Explanation:

Transposons need to regulate their copy number to avoid errors with chromosomal pairing during meiosis and mitosis such as unequal crossover.

A typical example of this error is called the Alu Sequence or Elements. Alu elements contain more than one million copies found everywhere in the genome of human beings.

Many inherited human diseases such as cancer are related to Alu insertions.

Cheers!

Final answer:

To minimize their negative impact on a host cell's genome, transposons need to regulate their copy number. Unregulated replication could lead to harmful mutations.

Explanation:

Transposons, also known as jumping genes, are sequences of DNA that can move around to different positions within the genome of a single cell. Their movement can cause mutations, which can have negative impacts on the host cell. In order to limit their negative impact on the host cell's genome, transposons need to B. regulate their copy number. If they did not manage this, over-replication of transposons could overload the cell with unnecessary genetic material, leading to harmful mutations or even cancer.
