Both klebsiella pneumoniae and streptococcus pneumoniae avoid phagocytosis by releasing a-b toxins that kill leukocytes.

1 answer:

7 0

This is a false statement.

Klebsiella pneumoniae and Streptococcus pneumoniae are two bacteria who are encapsulated, that means that they are surrounded by an envelope. This capsule is critical to their pathogenicity since it protects them from the phagocytes of the human immune system. Certain proteins located on the surface of their capsule prevent the phagocytic cell from adhering to the bacteria and engulfing it.

During the process of translation in a eukaryote messenger RNA is spliced in the nucleus. amino acids are synthesized by RNA pol

svetlana [45]

Answer:

mRNA interacts with ribosomes in the cytoplasm.

Explanation:

The correct option would be that mRNA interacts with ribosomes in the cytoplasm.

Translation involves the use of genetic codes in mRNA to synthesize amino acids that are eventually linked together by polypeptide bonds to form proteins.

During translation, the mRNA synthesized in the nucleus is transported into the cytoplasm where it gets attached to the ribosome and another RNA - the tRNA. The codons on the mRNA eventually match with the anticodon of the tRNA with the later releasing the amino acid that corresponds to each codon.

Hence, the correct answer out of all the options is that mRNA interacts with ribosomes in the cytoplasm.

finlep [7]

Hi there, I come in behalf of jcherry99,

So, first question -

This shouldn't be that much of an issue, since we have the text to help us out, but I'll try breaking it up into more simpler words:

The placenta is incide the uterus, where the baby starts forming. As you might already know, babies do not eat while they're inside woman's bellies:

So how do they feed?

They feed throught the umbilical cord.

So why is the placenta there? Why would the baby want anything apart from food?

The placenta, instead of trading food with the baby, regulates temperature, supplies it with nutrients, exchanges gas with the mother (which the mother later exchanges with the environment) and gets rid of waste.

And, food is not everything for a baby that is in the urge of developing complex muscles, bones, etc.

Second "question" -

I do not actually know what I'm supposed to do, since there is no question. But I can tell you this - the information contained in part B is correct:

The amnioic sac provides babies with a liquid which allows him to move freely in the uterus, which is very helpful. But, note that he doesn't start moving randomly, he is always in a fetus or similar-to-fetus position.

Hope it helped,
