c. protists
d. bacteria

Answers

Answer 1
Answer:

Answer: The correct answer is- C) Protists.

Dysentery is an inflammatory disease of the intestine, especially of the colon region ( a part of large intestine) that causes extensive pain in the abdomen and severe diarrhea. Apart from this, it also includes symptoms such as fever and an incomplete defecation feeling.

Amoebic dysentery is also known as amoebiasis and caused by Entamoeba histolytica, which is a protist.
Answer 2
Answer: Amoebic dysentery (amoebiasis) is an infection of the intestine (gut)caused by an amoeba called Entamoeba histolytica that, among other things, can cause severe diarrhoea with blood. But it may cause milder chronic symptoms of: frequent loose stools. abdominal pain.

Which modification is crucial in preparing an mRNA strand for proper translation? removal of introns and the splicing together of exons joining of ribosomal subunits to form a ribosomal complex removal of exons and the splicing together of introns addition of a poly-A tail addition of a poly-U tail

Answers

Removal of introns and the splicing together of exons.

Introns are regions of the DNA code that do not code for amino acids; therefore, they need to be removed before the mRNA strand is translated. Exons are the parts of the strand that do code for proteins, so they need to be pieced together once the introns are removed.

Glucose is not able to pass through a semi-permeable cell membrane. If the cells need sugar to make ATP and carry out cellular processes, how does the sugar get into the cell?A) passive transport by diffusion through proteins
B) active transport using ATP and carrier proteins
C) passive transport by osmosis through the proteins
D) active transport using a process called phagocytosis

Answers

The correct option is passive transport by diffusion through proteins.

What is passive transport?

A type of cellular transport known as passive transport involves the movement of molecules and ions along concentration gradients. It indicates that a drug has a propensity to migrate from a region of higher concentration to a region of lower concentration.

Contrary to active transport, another type of cellular transport, which fundamentally requires ATP to move substances against their concentration gradient, the process does not require metabolic energy (e.g. ATP) because the chemicals are moved downhill or along their concentration gradient.

The four main methods of passive transport are osmosis, filtration, simple diffusion, and assisted diffusion.

Therefore, The correct option is passive transport by diffusion through proteins.

Answer:

Body

Explanation:

Answer:

Systemic circulation is the movement of blood between the heart and therestofthebody.

Explanation:

The oxygenated blood will pass through the left ventricle to arteries then the capillaries of the body. After the oxygenated blood is distributed to all parts of the body, the now deoxygenated blood will return through a network of veins thus, to the right atrium of the heart.
