Answer:
Plants
Explanation:
An abiotic factor is a nonliving thing of condition, such as climate or habitat, and it influences (or affects) an ecosystem and the organisms in it.
Amylases' main function is to hydrolyze the glycosidic bonds in starch molecules.
<h3>Which molecule is hydrolyzed and digested by amylase?</h3>
Amylase is an enzyme that separates glucose molecules from starch. Both plants and animals use amylase when digesting starch. amylase, any limb of a class of enzymes that imbues the hydrolysis (splitting of a compound by the inclusion of a water molecule) of starch ...
Amylase is any member of a class of enzymes that activate the hydrolysis (splitting of a compound by the limb of a water molecule) of starch into smaller carbohydrate fragments such as maltose (a molecule composed of two glucose molecules).
So we can conclude that Amylases are usually referred to as a class of enzymes that catalyzes the hydrolysis of starch into glucose and maltose.

Answer:
Mutations affect evolution by increasing genetic variation and the potential for individuals to differ.
N an experiment, suppose that the wings of fruit flies were clipped short for fifty generations. The fifty-first generation emerged with normal-length wings. This observation would tend to disprove the idea that evolution is based on
a. inheritance of natural variations
b. inheritance of acquired characteristics
c. natural selection
d. survival of the fittest
Inheritance of acquired characteristics. Thus, option "B" is correct.
<h3 /><h3>What is inheritance of acquired characteristics?</h3>
For fifty generations wings of fruit flies were clipped. Hence they acquired this trait in their lifetime and not genetically. If acquired characteristics were capable of passing on to next generation, 50 generations would have been enough to inculcate this clipped wing trait in fruit flies. Despite it, the fifty-first generation did not have clipped wings.
Hence evolution can not occur without genetic variation. A character simply acquired in a lifetime does not create a difference in germ cells and hence is not enough to be passed on to next generation or cause evolution

Answer:
<em>The correct option is d) distal humerus fracture</em>
Explanation:
The humerus is one of the three bones which join to make up the elbow joint. A break in the lower end part of the upper elbow results in distal humerus fracture. Such types of events are caused due to high energy collisions such as during an accident. The distal humerus fracture can be treated through a surgery. During the surgery, the normal motion of the humerus is tried to be restored.
