Describe the advantage of an excretory system for terrestrial animals

1 answer:

7 0

The excretory system allows animals to remove metabolic waste their bodies. Many of these substances are potentially toxic. in Mammals nitrogenous toxins like urea are expelled through liquid urine while in reptiles and birds the nitrogenous compounds are expelled as a solid. This allows birds and reptiles to use less water in the processes of metabolism.

A 10-7 is performed on a culture of bacteria in order to perform viable plate counts. From the dilution, *0.1 mL* of solution is

marishachu [46]

Answer:

$66 * 10^8$ CFU/mL

Explanation:

Given -

a) Number of colonies of bacteria is equal to $66$

b) Total volume of the solution is equal to $0.1$ mL

c) Dilution factor is equal to $10^{-7}$

As we know that

CFU/mL $= \frac{N * DF}{V}$

Where N is the number of bacterial colonies, DF is the dilution factor and V is the volume

Substituting the given values in above equation, we get -

CFU/mL $= \frac{66* 10^7}{0.1} \\= 66*10^8$

Which one of the codons below would stop the translation of mRNA by ribosomal subunits?

Ostrovityanka [42]

Answer:

The correct option is D) UAG, UAA, UGA

Explanation:

The amino acid sequencing code or mRNA code contains specific codes which start and stop the process of translation at the right time. If the stop codon were not present then the ribosomal machinery would have made faulty proteins. If the stop codons are not at the right place, then it results in the production of faulty proteins. The stop codons which terminate the process of translation are UAG, UAA and UGA.
