Answer:
Option B, both evolutionary history and their own individual life histories.
Explanation:
Physical anthropologists study about both the evolutionary background of an individual as well as the environmental stresses faced by him/her. They believe the identity of an individual is affected by the following – family background (genetic history), culture is which he/she has been brought up, and also the societal elements. Due to this reason Physical anthropologists focus on different areas such as forensic, skeletal biology, Primatology, human biology etc.
Hence, option B is correct
<span>Stem cells are found in multicellular organism,they are undifferentiated in nature and can form other special cells or could divide in further stem cells by mitosis.The person with brain or spinal cord injury would be interested cause these cells could be used in future to cure the problem.Human embryonic stem cell (HESC) research is ethically and politically controversial because it involves the destruction of human embryos.The resource used was paper by B Lo named 'Ethical Issues in Stem Cell Research'.And according to me research in this field is important for development of mankind</span>
Answer:
Metaphase
Explanation:
Taxol is an anti-mitotic chemical which is used to treat cancer.
The taxol act by binding the microtubules which act as cytoskeletal structure. The microtubules are involved in the segregation of the chromosomes during the division of the cell.
The microtubules allow the movement of the chromosomes in the dividing cell during anaphase.
If the cells are treated with the taxol then the cells will be observed at the metaphase in which the chromosomes are aligned in the equatorial line. The microtubules will separate the chromosomes after the metaphase or during the anaphase but since the taxol prevents the depolymerization of the microtubules, therefore, cells are found in the metaphase.
Thus, Metaphase is correct.
Answer:
A solar eclipse happens when the moon moves in front of the Sun as seen from a location on Earth. During a solar eclipse, it gets dimer and dimmer outside as more and more of the Sun is covered by the Moon. During a total eclipse, the entire Sun is covered for a few minutes and it becomes very dark outside.
