Answer:
No, I don't reckon that water is alive. I don't think that it is "dead" either. It simply just... exists. However, it DOES hold life within it. But the water itself is not alive, because for something to be considered "alive", it must meet the requirements of responding to stimuli, reproducing and growing, and must be dependent on its environment. Water itself cannot be dependent on an environment, because it IS an environment.
This is just my opinion though :)
Answer:
Sickle cell disease is due to a type of substitution mutation.
Explanation:
Sickle cell disease is a condition that is transmitted from parents to children in an autosomal recessive inheritance pattern. It is due to a mutation that is capable of altering the shape of the erythrocyte, as well as its ability to circulate and carry oxygen.
The mutation that occurs in sickle cell disease is due to an alteration in the β-chain of hemoglobin, caused by the substitution of thymine base by adenine in the DNA that determines it. As a result, valine replaces glutamic acid in the β-chain amino acid sequence, with the consequences described.
- <em>The other options are not correct because </em><u><em>deletion, duplication and translocation </em></u><em>correspond to chromosomal mutations, not responsible for sickle cell disease.</em>
<span>The process is called Precipitation.
Water evaporated into the atmosphere. Due to the very low temperature of the
atmosphere, the vapor condenses and it is turned back into a non-gaseous form,
and because of gravity, it falls back to the ground in various forms, such as
rain, snow, sleet, or hail. </span>
