Question 34 (1 point)
is essential if bones are to retain normal proportions and strength during long-bone growth as the body increases in size and
weight
a.Rickets
b.Bone remodeling
c.Ossification
d.Bone maturation

Answers

Answer:

b.Bone remodeling

Explanation:

Bone remodeling is also known as bone metabolism is a process in which bones undergo bone resorption where old or mature bines tissue is removed from the skeleton and ossification (formation of new bone tissue).

Bone remodeling is a lifelong process that is influenced by the growth hormone/IGF-1 system that is stimulated when the body increases in size and  weight.

Hence, the correct answer is "b.Bone remodeling".

Which of the following characteristics of enzymes is NOT correct?

A)The substrate is the substance upon which the enzyme acts.

B)The induced-fit or lock and key model describes how enzymes work.

C)An enzyme is unchanged as a result of a reaction.

D)The efficiency of an enzyme is not affected by temperature.

Answers

D is incorrect. The efficiency of an enzyme is affected by temperature

The statement that represents an incorrect characteristic of enzymes is as follows;

The efficiency of an enzyme is not affected by temperature.

Thus, the correct option for this question is D.

What are enzymes?

Enzymes may be defined as the type of biocatalysts that significantly increase the rate of a chemical reaction without being changed in the overall process. It is thought that all cellular reactions and processes are mediated by enzymes.

Enzymes include a number of characteristics. Some of them are most of the enzymes are proteins. They are highly specific. They exhibit enormous catalytic power.

The substrate is the substance upon which the enzyme acts. The induced-fit or lock-and-key model describes how enzymes work. The temperature and pH directly affect the efficiency of an enzyme.

Therefore, the correct option for this question is D.

What is the reason of dividing Endoplasmic Reticulum Into two types.
Explain in detail.
Please answer

Answers

Answer:

We divide ER into two types because Smooth ER(SER) do not have ribosomes and Rough ER(RER) have ribosome thus former is also called Agranulated ER and Latter is called Granulated ER. SER is not involved in protein synthesis its main function is synthesis of lipids carbs steroid thus it is found in Adipose cells, interstitial cells, liver cells. RER have ribosomes so they are involved in protein synthesis so they are present in protein synthesising cells such as salivary glands and pancreas.

Which statement correctly describes the offspring of asexual reproduction?
Choose 1 answer:
They result without the fusion of gametes.

(Choice B)
B
They vary genetically from the parent.

(Choice C)
C
They contain half of the genetic information of the parent.

(Choice D)
D
They develop very slowly compared to offspring of sexual reproduction.

Answers

Answer: the answer is A “They result without the fusion of gametes”

Explanation:

The statement that correctly describes the offsprings of asexual reproduction is: they result without the fusion of gametes.

ASEXUAL REPRODUCTION:Asexual reproduction is a type of reproduction that involves a single parent organism. The single parent cell gives rise to two new daughter cells by undergoing division.

As a result, the new organisms are genetically identical to one another, hence, genetic diversity is not ensured.

On the other hand, sexual reproduction involves the fusion of gametes to produce genetically different organisms.

Dr. Naskrecki believes that scientists will eventually identify between 50,000 and 100,000 species in


Gorongosa National Park. Why do you think he suspects there are so many more than the 2,829


species they have already identified living in the park?

Answers

Answer:

The reason why Dr Naskrecki thinks he suspects there are so many more than the 2,829 species they have already identified living in the park is because there are many species that has been identified in the world because humans haven’t gotten to most parts of the earth which makes it a lot undiscoverable.

Another one is that the species multiply rapidly and easily.
