Answer:
d
Explanation:
Fishes are aquatic vertebrates having scales, pharyngeal gill slits and paired fins. ... Most fish are ectothermic ("cold-blooded"), allowing their body temperatures to vary as ambient temperatures change. fishes have scales that covers the skin of fishes. Thus, the correct answer is option D.
Geologists in Egypt and Ethiopia are comparing rock samples from rocks found in the two countries. They are sharing information about the rocks to figure out whether they are the same or different types of rock. The information is as follows: Rock A formed from small pieces of rock.
Phlebotomy refers to a collection of venous blood. This operation can be practiced on all the superficial veins of the body, on those of the foot, the leg, the neck, the whole upper limb. It must be done in an area where there is a protruding vein and the least sensitive to limit pain to the patient. It should not be done in an altered, injured or infected area (like bruise)
The blood is collected on tubes with or without anticoagulant according to the analyzes that one wants to practice.
The reason for choosing the sampling site is for the most part practical, the veins are easily identifiable, and easily accessible for paramedical personnel. Their collection is less dangerous than that of arteries, which are generally thinner and close to the peripheral nerves.
Answer:
Yes, because each daughter cell contains replicated genetic material, which are exact copy of one another.
Explanation:
Mitosis is a kind of cell division that results in two daughter cells that are genetically identical to the parent cell. Prior to the mitotic process, the cell undergoes DNA replication in the Interphase stage. DNA replication produces a replicated copy of the genetic material (DNA) to form two copies of each chromosome in the nucleus.
This replication gives rise to two copies of the DNA borne on replicated chromosomes called SISTER CHROMATIDS. During Anaphase stage of Mitosis, the sister chromatids separate into opposite poles and eventually into two cells after CYTOKINESIS (cytoplasmic division).
Each daughter cell now contains a nuclei that contains exact copies of genetic material without any form of recombination. Hence, each daughter cell is said to be genetically identical to the parent cell.
