Explain why it is necessary to use the same restriction enzyme to cut the desired gene from the source and to cut the plasmid. I

Novay_Z [31]3 years ago

Answer:

It is necessary because of the base pairing between the desired gene and plasmid

Explanation:

Restriction enzymes are enzymes that recognize the specific DNA sequence-restriction site, double-stranded cut DNA and produce ends with a single-stranded overhang. The overhangs of the plasmid can stick together with overhangs of gene of interest by complementary base pairing.  Joining of ovarhangs is done by the enzyme DNA ligase.

Scientists calculated the net primary productivity at two different forest sites. Both forests have the same gross primary produ
Katen [24]

Answer:

The answer is C.

Explanation:

Net Primary Productivity is a term that is used to express the difference between CO2 that is taken in by the plant with photosynthesis minus CO2 that the plant releases.

The two forest sites given in the example may not have the same biodiversity and the same species of plants so we can't be sure of option B.

Again for the same reasons, we can't be sure of option D because we do not know the specific plant species in each forest since they are in different areas.

Option A can be ruled out for the same reasons, the lack of information about the forest sites, since we do not know the death rate of the plants in either of the forests.

Option C can be true because forest A has a higher net primary productivity rate which can be an indication of lower respiratory activity hence lower CO2 production, resulting in the given higher net primary productivity.

I hope this answer helps.

<u>2</u>, <u>1</u>

Igg possesses <u>2</u> binding sites for antigen, and the t-cell receptor possesses <u>1</u> binding sites for antigen.

<h3>IgG: What Does It Mean?</h3>
  • Known as immunoglobulin G, It is an antibody of some sort.
  • Your immune system produces antibodies, which are proteins, to combat pathogens.
  • Your cerebrospinal fluid's levels of IgG are measured using a CSF IgG index.
  • Normally, your cerebrospinal fluid contains very little IgG.

<h3>What is the role played by IgG in the body?</h3>
  • IgG is typically the most prevalent antibody in blood.
  • It guards against infections.
  • Therefore, infections are more likely to affect those with IgG deficiencies.
  • Your body produces unique proteins known as immunoglobulins or antibodies when it senses an attack.

<h3>When IgG is positive, what happens?</h3>
  • The presence of IgG indicates that the infection occurred several weeks to months ago.
  • Additionally, it implies that you might no longer be contagious.
  • IgG suggests that you might have some viral immunity, though you might not.

The ant, the spider and the beetle are secondary consumers?
brilliants [131]
Insects are very common not only in today's world but also in ancient days. It is also estimated that the population of insect are 10 times more than thehuman beings. It is little bloodcurdling to hear but it is the fact. They are found in all parts of the world even in the ocean. Insects are astonishing creatures it is quite interesting to learn about them. Insects are very advantageous to man and his environment.

Insects are small species that is characteristic as an air breathing animal with a hard jointed exoskeleton. The whole body of the insects is divided into three parts: The head, thorax, and the abdomen.

Insects are classified into different known species in the world but still some new species are being discovered. The known species can be classified into 32 orders with 125 different families and about 500,000 species. Among them the Beetles are the largest group. Insects act as the varied group in the animal world.

Many insects act as the primary consumers for other animals since they are herbivores. These insects are rich in protein and energy which they provide to the secondary consumers also known as carnivores. Spiders, wireworms etc, act as the secondary consumers which cannot survive without depending on the primary consumers. Both the primary and secondary act as the prey to the tertiary consumers.

Insects help with a lot of important functions in our ecosystem. Mainly they help in decomposition of the waste products and pollination. These two acts of the insects led a greener environment. Decomposition of dead and waste materials provides more nutrients to the soil thus helping the soil to regain its health. Bugs such as ants, beetles burrow the soil to provide channels for water and air ventilation to the soil. Bees help in pollution thus helping in plantation. Bugs help the gardeners by preventing the plants from aphids and caterpillars. So without insects the world would not have see a fast growth that the way it is today.

Insects are exceedingly a diverse type of animal. The structure of the insects varies greatly with the different types of species. But the basic anatomy of the insect is the same. All the insects have an external exoskeleton and the body is divided into three major segments: head, thorax, and abdomen
