Answer:
The correct answer is - 40%.
Explanation:
The condition of the shock in an individual occur if she experienced the blood loss 40 % or more of her total blood pressure during pregnancy as she require enough amount of blood for the essential body organs to function.
As the fetus grow the women's blood volume is also increases to accommodate accordingly. This condition leads to blood loss of the mother. The critical limit is 40% of total blood.
Thus, the correct answer is - 40%
Answer:
The process where part of the DNA is saved during replication is known as semi conservative replication.
Explanation:
During cell division, a cell must first replicate its DNA (Deoxyribonucleic acid). When a cell divides into daughter cells , the DNA of the parent cell must be copied because DNA contains the genetic material of an organism. DNA replication is the process in which DNA is copied during the cell division cycle. During replication, the complementary strands of the original double helix DNA are separated and one of the two strands in the original molecule is saved in the new DNA molecule. Thus the new DNA molecule is made of an original strand and a newly synthesized strand. So the DNA replication is known as semi conservative replication. Each strand of the original DNA molecule is referred as the template strand because it provides information for the production of newly synthesized strand. It takes place inside the nucleus
of a cell during the s stage of the cell cycle. During replication, helicase enzyme breaks the hydrogen bonds between the complementary bases (Adenine with Thymine, Cytosine with Guanine) and unwinds the double helix of DNA. The two separated strands create a Y-shaped replication fork and act as templates for the synthesis of new strands of DNA. Enzymes known as DNA polymerases create the new strands.
Answer:
Sea shell fossils are found in a mountain-top cave in New Hampshire.
Explanation:
Answer:
option B
Explanation:
igneous rocks are the rocks which are formed by the cooling of molten magma cooling can be on the surface or below the earth surface.
sedimentary surface is the rocks which are formed by the weathering or some chemical action upon the rock due to the passage of time.
metamorphic rocks are those rocks which are formed due to the high pressure and temperature acted on the rocks.
so, the best answer will be sedimentary rock
hence, the correct answer is option B
Answer:
Relative velocity simply means velocity relative to a certain observe point, in this case, the river shore.
This is a type of complex movement; a boat is moving with a certain velocity, let's say 8 m/s. However, the river this boat moves on also has its velocity, let's say 2 m/s. Since the shore isn't moving, the velocity of the boat relative to the shore will be simple resultant velocity of the boat's and the river's velocities.
Let's illustrate this with two examples:
1) if the boat is moving downstream both are moving in the same direction, so the resultant will be 8 m/s + 2 m/s = 10 m/s.
So, any spectator looking at the boat from the shore will think its velocity is 10 m/s, when in reality it's 8 m/s.
2) if the boat is moving upstream, these two velocities have opposite directions, so the resultant will be 8 - 2 = 6 m/s
So, as a short summary, relative speed is an object's speed in regard to another chosen referent point.
