Why are Canada’s Evergreen Forests considered “Earth’s Northern Lungs”? (think about the photosynthesis equation)

Answers

Answer:

Although trees have responded to global warming in the past‐ to temperatures higher than they are now- the rate of change predicted in the 21st century is likely to be unprecedented. Greenhouse gas emissions could cause a 3°-6°C increase in mean land surface temperature at high temperatures and temperatures latitudes. Despite this, few experiments have isolated the effects of temperature for this scenario on trees and forests. This review focuses on tree and forest responses at boreal and temperate latitudes, ranging from the cellular to the ecosystem level. Adaptation to varying temperatures revolves around the trade- off between utilizing the full growing season and minimizing frost damage through proper timing of hardening in autumn and dehardening in spring.

Cofactors do not bind to the enzyme, whereas coenzymes frequently bind loosely to an enzyme's active site and help recruit substrates. Coenzymes are organic compounds. Thus, option A is correct.

What is the importance of Cofactors and coenzymes?

Cofactors and coenzymes are substances that support the proper operation of an enzyme or protein.

Cofactors are organic and inorganic substances that help enzymes catalyze processes. The majority of coenzymes are vitamin derivatives that are soluble in water by phosphorylation.

Typically, cofactors are used to provide chemical groups or qualities that are absent from other chemical groups.

A cofactor like ATP, for instance, has a special capacity for transferring energy to power chemical reactions like the activity of enzymes and transport proteins.

Therefore, Cofactors and coenzymes to support enzyme function.

If a red-eye female fly is crossed with a red-eye male fly, could they produce offspring with white eyes? Briefly explain your answer. Your answer must include a Punnett square that proves your answer.

Answers

If the red-eye parents are homozygous, no. But if the red-eye parents are heterozygous, yes.

Monohybrid crossing

We are assuming that the red-eye trait is dominant over the white-eye trait. If two red-eye parents are crossed with one another, whether they could produce white-eye offspring would depend on the zygosity level of the parents.

Assuming that red-eye is R and white-eye is r. If the two parents are homozygous red-eyed, their genotypes would be RR. Crossing the two:

       RR    x     RR

   RR   RR   RR   RR

All the offsprings would be RR and there is a zero chance of producing a white-eye offspring.

Now, assuming that the two parents are heterozygous:

        Rr    x    Rr

     RR   Rr   Rr   rr

Both RR and Rr are red-eyed while rr is white-eyed. The Punnet's square for the cross can be found in the attached image.

In other words, it will only be possible for the two red-eye parents to produce white-eye offspring if they are both heterozygous. Any other genotype will give a zero chance of white-eye offspring.

Suppose that you began a one-year study of tuberculosis (TB) in St. Petersburg on January 1st, 2018. You enrolled 200 residents in your study and checked on their TB status on a monthly basis. At the start of your study on January 1st, you screened all 200 residents. Upon screening, you found that 10 of the healthy residents were immigrants who were vaccinated for TB and so were not at risk. Another 10 residents already had existing cases of TB on January 1st. On February 1st, two residents developed TB. On April 1st, three more residents developed TB. On July 1st, three of the residents who had existing TB on January 1st died from their disease. The study ended on December 31, 2018. Assume that once a person gets TB, they have it for the duration of the study, and assume that all remaining residents stayed healthy and were not lost to follow-up.

What was the prevalence of TB in the screened community on January 1st?

Answers

Answer:  5%

Explanation:

The Prevalence rate is the term used to describe the percentage of a population that have contacted the disease being tested for. It is usually done over a certain period or a certain time.

The prevalence of TB in the screened community on January 1st therefore is;

= Number of infected/ No. of Tested residents

= 10/200

A biochemist extracts a molecule from a cell. This molecule catalyzes a chemical reaction. To what class of molecules does it belong?

A. Proteins
B. Carbohydrates
C. Lipids
D. Nucleic acids

Answers

Answer:

proteins create enzymes which speed up reaction

Enzymes are the molecules that catalyze biological reactions, while a catalyst is a material that aids in the occurrence of a chemical reaction, hence option A is correct.    

How do enzymes catalyze chemical reactions?

The crucial function of decreasing the activation energy of chemical events inside the cell is carried out by the majority of enzymes, which are proteins.

Enzymes are biological catalysts that significantly speed up reaction rates and have the propensity to be particular about particular reactants and products, a substrate is a term for the reactant in an enzyme-catalyzed process.    

Proteins are called enzymes to catalyze biological reactions that would not occur without them. For chemical reactions like digestion and cellular metabolism, these enzymes are necessary.

Therefore, since enzymes are a specific type of protein that catalyzes chemical events inside cells, they are excellent therapeutic targets, hence option A is correct.
