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

A receptor site that a molecule can bind to that changes the shape of the active site is called a(n)
a) allosteric site
b) active site
c) disulphide bridge
d) MHC receptor
Answer:
a) allosteric site
Explanation:
An allosteric site is a site on an enzyme other than the active site where a molecule that is not a substrate binds. This changes the shape of the enzyme, making it harder for the substrate to bind and inhibits enzyme activity.

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.
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.Learn more about asexual reproduction at: https://brainly.com/question/4100787?referrer=searchResults

1) State whether plants perform cellular respiration and explain why or why not.
2)Explain which cell would likely contain more mitochondria, a muscle cell or a skin cell. Use your knowledge of energy; mitochondria and their function to support your answer.
Answer:
1) plants use photosynthesis to produce glucose, but the use cellular respiration to release energy from glucose so yes they do perform cellular respiration
2) a muscle cell because mitochondria is the site of cellular respiration (releasing energy from glucose) and they need more energy for muscle contraction
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.
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.

Which type of information can scientists collect using a seismograph?
a) slight shifts in the inclination of a surface
b) pollution levels in the air after a volcanic eruption
c) vibrations occurring inside Earth
d) temperatures of molten rock inside Earth
Answer:
C
Explanation:
Vibrations occurring inside Earth
The type of information that scientists collect using a seismograph is vibrations occurring inside Earth. The correct option is c.
What is seismograph?A seismometer is a measuring device that detects ground noises and shaking caused by earthquakes, volcanic eruptions, and explosions.
Seismographs are typically made up of a seismograph, a timing device, and a recording device.
Seismographs are devices that record the movement of the ground during an earthquake. They are installed in the ground all over the world as part of a seismographic network.
To better understand seismic waves, scientists developed and used a device known as a seismometer. Seismometers now assist scientists in predicting earthquakes.
Scientists use seismographs to collect information about vibrations that occur within the Earth.
Thus, correct option is c.

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
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".
