Biology
1 answer:
hichkok12 [17]3 years ago
6 0

Answer:

The correct answer is -

10. 20 J

11. 29.31 %

Explanation:

According to the law of 10% energy transfer, the energy only transfers 10% energy from one tropic level to another and the rest 90% lost in the form of heat during the metabolic and excretion process.

So, 2000 J transfers only ten percent to the primary consumer that is 200 J and then ten percent of that transfers to long-tailed weasels that are 20 J.

11. The percentage efficiency -= energy after transfer*100/transfer before the transfer

= 350*100/1170 = 29.31%

Sickle-cell anemia results from a point mutation in the HBB gene. The mutation results in the replacement of an amino acid that
Marizza181 [45]

Answer:

a) properties of the molecule as a result of abnormal interactions between adjacent hemoglobin molecules

Explanation:

In sickle cell disease, for example, a nonpolar amino acid (valine) replaces a polar amino acid (glutamate). This substitution of amino acids reduces the hemoglobin’s water solubility. The mutated hemoglobin molecules form long, stiff and rod-like crystals inside red blood cells which are otherwise not formed by normal hemoglobin molecules.

These abnormal crystals of hemoglobin cause the deformation of RBCs making them sickle-shaped that cannot properly squeeze through narrow blood vessels. Therefore, the substitution of single amino acid results in abnormal interaction of two or more hemoglobin molecules that are not exhibited by normal hemoglobin molecules.
