il63 [147K]

What are two ways that some prokaryotes are able to survive in extreme environments?

Answer:

1. Presence of thick cell wall in prokaryotes help them to survive in hypo-osmotic and hyper-osmotic conditions.

2. Production of endospores by bacteria. Bacteria use these structures to produce off sprigs because these structures are heat and drought resistant. They germinate when the conditions became favorable for growth.

Describe three ways that microorganisms in soil contribute to the ecosystem as a whole.

Answer:

1. As decomposer return the nitrogen contents back to ecosystem.

2. Bacteria detoxify may harmful substances present in water bodies therefore some species of bacteria are used for bio-remediation of ecosystem.

3. Bacterial byproducts help plant to grow faster because these byproducts act as stimuli for plant growth.

Give two examples of genera that produce endospores, and explain why they are important in human health.

Answer:

Endospore Producing Genus:

Bacteria belongs to genus Bacillus and Clostridium produce endospores.  

Importance for humans.:

1. Bacillus species are used to produce antibiotics, metabolites, enzymes which help in curing human diseases.

2. While species of Clostridium cause food poisoning in human.

What are coliforms? Why are they important in assuring water quality?

Answer:

Coliforms are gram negative bacteria have road like shape found in spoiled water.  

Importance:

These bacteria are important indicator of polluted water therefore in water quality testing their presence tells us about the water quality that how much is this water polluted.

Why is E. coli the indicator bacterium for fecal contamination?

Answer:

E. Coli found in the intestine of humans. As E. Coli itself does not cause mild infections therefore its presence indicates the presence if other deadly pathogens which may cause dangerous diseases to human.

​the vitamin that is responsible for regulating the absorption and metabolism of calcium and phosphorus for healthy bones and
PSYCHO15rus [73]
The answer is vitamin D. This is actually a group of vitamins of similar molecular structure responsible for facilitating increased absorption of calcium, magnesium and phosphate from the gut. The most important of the vitamin D compounds are vitamin D3 and D2. While vitamin D can be obtained from your diet and supplements, the major source of vitamin D is from a chemical reaction dependent on skin exposure to the sun.

What can electron microscopes reveal
zloy xaker [14]
Answer:
Electron microscope is a device which is used to see microscopic objects using electon. In this tyoe of microscope electron is thrown on an object whose image is formed on the screen. It resolution power is 10,000X. If the internal structure of an object is to be observed then SEM is used, however for three dimensional structure, TEM is used.

Barred feather pattern is a Z-linked dominant trait in chickens. What offspring would you expect from (a) the cross of a barred
Bezzdna [24]

Answer:

Let the "barred" allele be caller B and the "non-white" allele b. Since chickens use chromosomes Z  and W to determine sex, hens would have chromosomes ZW, and roosters would have chromosomes ZZ. A Z-linked gene is represented as a superscript on the Z chromosome, Z^{B} for the dominant allele and Z^{b} for the ressesive allele.

A barred hen would have a copy of B on its Z chromosome, a non-barred rooster would have both copies of b on both Z chromosomes. Using Punnet squares to represent the crosses we get the following cases:

\begin{center}\begin{tabular}{ |c|c|c|c| }\ & Z^{B} & W \\ \ Z^{b} & Z^{B}Z^{b} & Z^{b}W \\ \ Z^{b} & Z^{B}Z^{b} & Z^{b}W \\ \end{tabular}\end{center}

That is a ratio of two barred heterozygote roosters to two non-barred hens. Crossing them we get:

\begin{center}\begin{tabular}{ |c|c|c|c| }\ & Z^{b} & W \\ \ Z^{B} & Z^{B}Z^{b} & Z^{B}W \\ \ Z^{b} & Z^{b}Z^{b} & Z^{b}W \\ \end{tabular}\end{center}

That is a ratio of one barred heterozygote rooster to one barred hen to one non-barred rooster to one non barred hen.

What type of molecule serves as the inorganic carbon reservoir for photosynthesis?
kupik [55]
The correct answer for 1 is carbon dioxide

That's because carbon dioxide is inorganic, which basically means it's not a compound used in creation of life, it's just inorganic matter.

The correct answer for 2 is <span>The photosystems transfer energy to the Calvin cycle in the form of ATP and NADPH.

These are then processed to produce even more ATP which creates energy for the organism.</span>
