You have a chart that illustrates a series of species with their common ancestor. This chart is a A. gene pool.
B. fossil record.
C. cladogram.
D. five-kingdom system.

Answers

Answer 1
Answer: The answer is C. Cladogram

The terms come from "clade" which refer to a group of individuals and their common ancestors

On the largest scale of cladogram, all living organism could be considered coming from the some ancestor. Because in the beginning of the world, before the mutation happened, we all come from a single cell organism

Basophilic stippling is seen in which excess

Answers

Answer/ Explanation: Basophilic stippling is seen in excess of certain substances, such as lead or other heavy metals, in the body.

1. Basophilic Stippling: Basophilic stippling refers to the presence of small, dark blue or purple granules in red blood cells (RBCs) when viewed under a microscope. These granules are aggregates of ribosomes and RNA, and they appear as tiny dots or speckles within the RBCs.

2. Lead and Heavy Metal Poisoning: Basophilic stippling is commonly associated with lead poisoning or exposure to other heavy metals like arsenic or thallium. When these substances enter the bloodstream, they can affect the production and function of RBCs in the bone marrow.

3. Mechanism: The exact mechanism by which lead or other heavy metals cause basophilic stippling is not fully understood. However, it is believed that these substances interfere with the normal synthesis and maturation of RBCs, leading to the accumulation of ribosomes and RNA in the cells.

4. Diagnostic Significance: The presence of basophilic stippling in RBCs can be an important diagnostic clue for lead or heavy metal poisoning. It is often observed in blood smears of individuals with chronic exposure to these toxic substances. However, it is important to note that basophilic stippling is not specific to lead poisoning and can also be seen in other conditions such as certain anemias or myelodysplastic syndromes.

In summary, basophilic stippling is observed in excess of substances like lead or other heavy metals in the body. It is a microscopic finding characterized by the presence of small granules within red blood cells. The identification of basophilic stippling can be a useful indicator for the presence of lead or heavy metal poisoning, although further diagnostic tests may be required for confirmation.
