Why did you not see any chloroplasts in the onion epidermal cells, unlike in the Elodea (Anacharis) cells?
-Chloroplasts in onion cells are hidden by the large central vacuole.
-The part of the onion viewed under the microscope grows underground.
-The purpose of chloroplasts is to make the plant green but onions are not green.
-Chloroplasts are organelles that absorb sunlight energy and perform photosynthesis.
-Plant parts that grow underground are not exposed to sunlight.
-Onions had chloroplasts before they were picked from the ground but the chloroplasts dried up and disappeared after being exposed to the sunlight.
-Onions are not plants and therefore do not have chloroplasts.
-Plant parts that are not exposed to sunlight cannot do photosynthesis.

NS has been diagnosed with idiopathic thrombocytopenic purpura (ITP). Explain what it is and who can get it.

Answers

Answer:

Idiopathic thrombocytopenic purpura or ITP is also known as Immune thrombocytopenic purpura that is a disorder in which there is an abnormality in the clotting of blood due to a decreasing number of platelets in an individual.

Platelets plays role in clotting the blood to prevent bleeding so this disorder leads to easy bruising, bleeding gums, and internal bleeding. It is an autoimmune disorder as in this case, an immune reaction takes place against one's own platelets.

It occurs in all age and sex groups however, it occurs normally in young children and females more often.

How long can blood flow to the brain be interrupted before death occurs?

Answers

Answer:

Brain cells start to die if they go without oxygen for just 3-4 minutes and that's exactly what happens during a stroke.

Explanation:

Stroke is an abrupt interruption of constant blood flow to the brain that causes loss of neurological function. The interruption of blood flow can be caused by a blockage, leading to the more common ischemic stroke, or by bleeding in the brain, leading to the more deadly hemorrhagic stroke.

Brain death can occur rapidly as cells begin to die off without any oxygen stores or new oxygen circulating to the brain.

If a protein will end up with 30 amino acids, how many codons, not including the STOP codon, were on the mRNA
transcript that produced it?

Answers

Answer:

30 codons

Explanation:

Translation is the second process of gene expression, which involves the synthesis of amino acid sequence from mRNA. This process occurs in the ribosome where the mRNA is read in a group of three nucleotide bases called CODON. Each codon specifies a particular amino acid.

Since one codon specifies or translates into one amino acid, a protein with 30 amino acids will contain 30 codons (exclusive of STOP CODONS) on the mRNA transcript.

The epithelium's tissue

The human body is made entirely of epithelial tissue. It supports a variety of bodily processes, including defense, secretion, absorption, and filtration.

A unique type of tissue called epithelial tissue can be found in the skin's outer layer.

The small intestine serves as the site of both digestion and absorption. The small intestine contains a straightforward columnar epithelium. The term "digestive epithelium" is sometimes used.

The pseudostratified columnar epithelium is present in the human olfactory mucosa. The skin serves as protection and contains epithelial tissue. The kidney contains glomerulus epithelium, which aids infiltration.

Therefore, the small intestine is where digestion and absorption occur.

In Genetics, a trait comprises of all the genetic instructions that are typically being transfered from the parent to their offsprings.

Hence, an organism inherit its genetic instructions from its parent.
