Answer:
Chemical reaction
Explanation:
Chemical changes happens when a substance combines with another to form a new substance (or unexpected color, temperature or smell), called chemical synthesis or, alternatively, chemical decomposition into two or more different substances
Answer:
The correct answer is option B. The tertiary structure of the beta subunit changes, exposing a hydrophobic cleft which allows hemoglobin to form long chains in RBC.
Explanation:
As it is clearly mention as there is point mutation that leads to single nucleotide change which results in to valine instead of glutamate. Valine is hydrophobic in nature not like glutamate. Valine aggregate and makes a rigid structure of molecules.
Due to this rigid molecule of valine aggregates, RBCs form a crescent or sickle like shape due to the higher viscosity and low solubility of Mutated hemoglobin in deoxy condition. It leads to formation of polymer that blocks the vessels.
Thus, the correct answer is option B.
I don’t know what a carry is but if you’re pushing, I guess that’s active since you’re using energy.
First they don't use oxygen, plants use the CO2 in the air and release oxygen out into the air after the plant used up the CO2
Answer:
In sexually reproducing organisms, each parent contributes half of the genes acquired (at random) by the offspring. Individuals have two of each chromosome and hence two alleles of each gene, one acquired from each parent.
