Answer:
Homology is a study of similar characters found in two species because of common ancestry.
Explanation:
1.Morphological homology: Species placed under same taxonomic category exhibit similar anatomical structures.
2.Ontogenetic homology: Species belongs to same taxonomic category embryological similarities
3.Molecular homology: Species show molecular similarities such as DNA,RNA and protein
An example of homology is seen in the skeletal strycture of vertebrates. That is arm of a human,leg of a cat,fin of a whale and wing of a bat.
Answer: they are called DNA polymerase and they’re proteins
Explanation:
Answer:
True.
Explanation:
Therapeutic cloning is the technique of using cloning procedures to generate embryonic stem cells that can be applied for the damaged organ or tissue replacement without getting the chances of any rejection. This can be achieved by putting a diploid nucleus from a body cell to a enucleated cell. Then from that cell an identical organ can be developed.
Answer:
.396 g/cm³
Explanation:
To find density, it is mass/volume
since the mass is 385 and the volume is 973, divide the two
385cm³/973g
This will give you .396 g/cm³
Answer: Vasodilation
Explanation:
vasodilation can be described as the process where the blood vessels widen within the body. Usually, it occurs when smooth muscles in the arteries and major veins relax and its major role is to distribute oxygen to different areas of the body, where it is needed most. It is a natural response of the blood vessels to low levels of oxygen or an increment in body temperature. There are certain health conditions related to vasodilation such as low blood pressure and inflammatory conditions.
