Answer:

The correct answer would be the option D.

The provided conclusion is not right as the speed of sound is much faster in water as compared to the speed of sound in air.

It is because the particles in water are much closer than the particles in the air. Consequently, they transmit the vibrations at a faster rate and thus, sound travels faster.

In addition, the muffling is not associated with the speed of the sound wave in the water. It occurs because human ears are evolved to hear sound in air due to which we hear clear sound in air.

Alika [10]

Answer:

Becky’s doctor provided only supportive care because the toxin that poisoned her, the demoic acid, has no known antidotes; which happen to be the only cure for toxins.

Antimicrobial were not part of Becky's treatment because Becky was infected by a toxin and not a microbial infection.

Diatoms are not different from eukaryotic cells or eukaryotes. they are Eukaryotes, which are different from prokaryotes. However both the eukaryotes (diatoms) and the prokaryotes possess cytoplasm, plasma membrane and ribosomes.

Explanation:

Demoic acid is a marine bio-toxin that results in Amnesic Shellfish poisoning (ASP). This biotoxin is produced by diatoms of the species <em>Nitzschia navis-varingica</em> of the genus <em>Pseudo-Nitzschia</em><em>. </em>This intoxication can result in symptoms ranging from gastrointestinal upset (vomiting, nausea, diarrhea, abdominal cramps, hemorrhagic gastritis) to neurological disturbances (including headaches, diziness, disorientation, vision disturbances, loss of short term memory, motor weakness, abnormal heart rhythm, unstable blood pressure, etc.). In more severe cases, it could lead to permanent short term memory loss, brain damage, coma, and death. Due to the lack of antidotes for this toxin, it is advised that medical attention be sought as soon as possible, where the patient can be closely monitored and cared for.

There's a difference between toxins and microbial infections. while Microbial infections are caused by harmful microorganisms infecting the body tissue and cells, toxins are harmful substances produced by microorganisms. Hence, the approach for treatment for both cases are different.

Diatoms are eukaryotic cells or eukaryotes, which are organisms that have a membrane enclosing in their nucleus, hence they have  a true nucleus and organelles bound by a membrane, supporting functions in compartments. Prokayotic cells or prokayotes, on the other hand, which are typically smaller, do not possess a protective membrane around their nucleus or any organelles enclosed by the membrane. Regardless of their differences, they still both share similarities. After all, they both are cells. So they have the basic features of cells. These similarities include the possession of a cytoplasm, ribosomes, plasma membrane.

The DNA, mRNA and tRNA are the essential nucleic acids that initiate protein synthesis. The DNA contains the genetic code of our human body in the form of chromosomes. It is composed of nucleic acids like uracil (U), guanine (G), adenine (A) and cytosine (C). The messenger RNA or mRNA carries this code called codons expressed in three-letter codes. Each amino acid has its own assignment of code. The mRNA carries this code to the ribosome which is the site for protein synthesis. The translational RNA or tRNA contains anti-codons to translate the codes in the mRNA into amino acids that link together to form proteins.

Suppose the size of a population of marmots is 300. According to genetic drift theory, what is the probability that a newly aris
arsen [322]

Answer:

E. 1/600

Explanation:

Hint:

The probability of fixation of a new neutral mutation is 1/(2N)

Given N as 300

= 1/(2×300)

=1/600

Therefore,

1/600 gives a sure fixation of one allele from the large population
