A sporozoite is the cell form that infects new hosts. A merozoite is the result of merogony that takes place within a host cell.

In Plasmodium, for example, the sporozoites are cells that produce in the mosquito's salivary glands, leave the mosquito during a blood meal, and drive liver cells (hepatocytes), where they generate. Cells infected with sporozoites ultimately burst, delivering merozoites into the bloodstream. Merozoites are non-motile.A merozoite is a daughter cell of a protozoan parasite. Merozoites are the consequence of asexual propagation. Sporozoites are designed by sporogony, a type of sexual or asexual reproduction by multiple fission of a spore or zygote, representative of many sporozoans.

Answer: The options are not given, here are the options.

A) No the DNA in circulating erythrocytes ins needed to help transport O2 through the capillaries

B) No circulating erythrocytes contain DNA.

C) Yes DNA is responsible for cell division in most cells

D) Yes circulating erythrocytes carry DNA nutrients through the capillaries

The correct option is B.

No circulating erythrocytes contain DNA.

Explanation:

Erythrocytes or red blood cells is a biconcave disc that contain haemoglobin which help to carry oxygenated blood in the body.

Circulating erythrocytes do not contain dna because they lack nuclei and organelles, cannot synthesize any RNA, therefore cannot divide and have limited repair capabilities.

Because they cannot carryout protein synthesis, no virus can evolve and invade the red blood cells.

Answer:

Explanation:

Urea is the cellular waste product that the kidneys remove from the blood.Kidneys are the two bean shaped organs that has several functions to keep the body healthy. It not only removes urea from the blood, but also helps in the formation of urine and maintaining the fluid level of the body. The two kidneys are placed on the two sides of the spinal cord. The blood enters the kidney through the renal artery. The nephron within the kidneys mainly take out the waste products and the excess water from the blood and purifies it.If the kidneys of a person fail to work properly then it becomes important to perform dialysis for taking out the waste materials from the blood.

Why is it difficult to observe individual chromosomes with a light microscope during interphase?

asambeis [7]

Answer:

They have uncoiled to form long, thin strands.

Explanation:

Chromosomes are present in cell nucleus and consist of chromatin. Genes are present in linear order on chromosomes. The chromosomes become visible under the microscope as distinct structures during cell division. When cells are not dividing, the chromosomes decondense to loose their individuality and make the mass of chromatin.

Chromatin is complex of DNA and packing proteins. As the cells enter the prophase stage of cell division, condensation of chromatin occurs and individual chromosomes become visible under microscope. Before that (during interphase), chromosomes are not visible as they are present in decondensed form.
