Answer:
(i) Available in the plant:
Chlorophyll
(ii) Available in the soil:
Water
(iii) Available in the air:
Carbon dioxide
(iv) Available during day:
Light / Light energy
Explanation:
For photosynthesis, your raw materials are chlorophyll (to absorb light energy from the sun), light, carbon dioxide, and water. The products are glucose and oxygen.
Chlorophyll can be found in the leaves of a plant.
Light is from the sun.
Carbon dioxide is taken in from surrounding air.
Water is taken in by the roots, along with mineral salts, before being distributed to other parts of the plant.
During the night, respiration takes place. You can think of it as opposite of photosynthesis. Materials are glucose and oxygen, and products are carbon dioxide and water.
Answer and Explanation:
when we talk about the touch receptors the face has the highest density of touch receptors and on second number finger tips has the second highest density of touch receptors
BENEFITS :
- easy in temperature sensing
- used to identifying objects
- the information which is related to sensing can be easily given by highest touch receptors
Answer:
There is a low probability that a future pregnancy would exhibit similar phenotypes since it probably was a germinative line mutation that affected that egg.
Explanation:
The malformations of the unborn child, probably are due to a mutation in the germ cell of any or both parents. Germline mutations are detectable changes in a sperm or egg that we can see when the fetus is growing, as malformations since the original germ cell that was mutated divided itself to give more mutated cells for all the different parts of the fetus.
Answer: Blood loss regulation
Explanation:
Positive feed back is response of body in which there is an increase in the effect of small disturbance and the effect is intensified on a system. The magnitude of the effect increases.
In case of blood loss the body releases clotting factors that helps in preventing the body from severe blood loss.
The body releases clotting factors and these clotting factors tend to release more and more clotting factors that begins the process of blood clotting in vessels.
This is an example of positive feedback which acts as a life saving cascade.
