Biology

Vesna [10]2 years ago
5 0
Soil particles vary greatly in size, and soil scientists classify soil particles into sand, silt, and clay. Starting with the finest, clay particles are smaller than 0.002 mm in diameter. Some clay particles are so small that ordinary microscopes do not show them. Silt particles are from 0.002 to 0.05 mm in diameter.

Discuss the meaning and importance of selective toxicity as it relates to antimicrobials.
Burka [1]
An antimicrobial<span> is an agent that kills microorganisms or inhibits their growth. </span>Antimicrobial <span>medicines can be grouped according to the microorganisms they act primarily against. For example, antibiotics are used against bacteria and antifungals are used against fungi.
</span>
Selective toxicity<span> refers to the ability of the drug to targets sites that are relative specific to the microorganism responsible for infection. Sometimes these sites are unique to the microorganism or simply more essential to survival of the microorganism than to the host.

Selective theory relates to antimicrobial because the antimicrobial is the drug that kills microorganisms and inhibits there growth,  selective theory is the ability of the drug.

Punnett squares provide an easy way to predict the possible genotypes for an offspring, but it is not practical to perform a Pun
castortr0y [4]

Answer:

True

Explanation:

There are certain limitations associated with the Punnett Squares. They are not useful in case of complex genetic inheritance such as linkage between two genes. In case of linkages it becomes difficult to estimate the distribution of genotypes and phenotypes. For example in case of  Nail-patella Syndrome and gene associated with blood group two genes lie on the same chromosome in close vicinity and hence there are high chances of inheritance of these traits in the offspring from the parent thereby causing  random distribution of the two traits. This random distribution cannot be captured through punnet square.  

The same problem is associated in case where a single gene is determined by multiple genes with graded effects of each gene.

Muscle soreness associated with strenuous exercise is at least partly due to
34kurt

Answer:

Anaerobic respiration resulting in oxygen debt, due to lactic acid accumulation.

Explanation:

After strenuous muscle activity extra oxygen is needed to re-convert lactic acid into glucose and ATP. As you exercise the liver anaerobically converts glucose to lactic acid and carbon dioxide this results in oxygen debts that needs to be repaid later.

Oxygen debt by definition is the amount of oxygen needed by muscles to oxidise lactic acid to glucose after muscle activity.
