Adenosine triphosphate <span>(ATP)
is the energy source for muscle contraction. Myosin is a motor protein that
interacts with actin filaments. When ATP is available, it binds to myosin and
is being hydrolyzed resulting in the conformational changes in myosin. This
leads to the movement of myosin relative to actin filaments.</span>
Answer:
The chance of a woman with an AB blood type and a man with an O blood type having a child with O blood is 0%.
Explanation:
A mother with blood type AB (AB) will pass either antigen A or antigen B to the offspring, while the father with blood type O (OO) will not pass any antigen.
The result of an AB X OO cross would be
Alleles O O
A AO AO
B BO BO
For this reason, the offspring of this couple will be
- <em>Blood type A (AO) 50%.
</em>
- <em>Blood type B (BO) 50%.
</em>
- <em>Blood type O (OO) none.
</em>
Heredity of blood type depends on the presence of surface antigens on the erythrocyte membrane. Blood type O occurs in persons whose red blood cells do not possess surface antigens A or B.
Surface antigens are what determine blood type, so
:
- <em>The presence of antigen A determines blood type A.
</em>
- <em>Blood type B depends on the presence of antigen B.
</em>
- <em>Blood type AB has both antigens.
</em>
Blood type O has no antigens, and for blood type O to manifest, it must have both alleles for O.
A mother AB and father O cannot have offspring with blood type O.
Condensation stage of storm formation is when a convection cell is created
Explanation:
When warm and moist air rises into the cold air that is called thunderstorm. Due to moisture that warm air becomes cooler. We all called it water vapor. It forms small water droplet and this process is understood as condensation.
The cooling of air drops which is lower in the atmosphere which becomes warm and rises again and rising and falling circuit is known as convection cell. Rising and falling is responsible of cloud formation
Answer:
C. <u><em>Prokaryotes only have one origin of replication to initiate replication</em></u>
<u><em /></u>
Answer:
In normal tissues there is a balance between the generation of new cells via cell division and the loss of cells via cell death. Old cells become damaged over time and are eliminated. This is an essential form of renewal. Examples include shedding of skin cells and the replacement of the cells lining our digestive tract. Like cell division, cell death is also tightly controlled. Cells frequently die by a process termed programmed cell death or apoptosis. 1Apoptosis is the cellular equivalent of a “self destruct” button.
