Answer:
2 & 4
Explanation:
The theory of spontaneous generation stipulated that life emanated spontaneously from ‘nothing’. This was believed to be true until Francesco Redi & Luis Pasteur later falsified this theory using an experiment. He had two plates of cooked meat. He covered one with a glass bowl and left the other open. The plate with a bowl did not develop maggots while the open one did. This showed that maggot was as a result of hatched eggs that were deposited by flies. Life, therefore, emanates from life.

The phosphorus in all biological tissues can be traced back to phosphorus weathered from rock.

The statement is true. There are two main anabolic stimuli for muscle that is exercise and protein ingestion. Protein not only provides the building blocks for the muscle, but also provides the trigger to stimulate muscle protein synthesis. Muscle protein synthesis is the physiological process of adding new amino acids to muscle proteins and is the primary mechanism of muscle growth.
This reduction in starch content occurred because starch was changed into simple sugars
<h3>Explanation:
</h3>
Starch is a polymeric carbohydrate consist of many glucose units linked by glycosidic bonds. The iodine test is used to test for the presence of starch. Starch will change color to an intense "blue-black" colour after the addition of aqueous solutions of the triiodide anion. To do it we can add Iodine-KI reagent to a solution or directly on a potato or other materials such as bread, crackers, or flour The reaction between amylose that present in lesser amounts and iodine is said to account for the intense color change seen.
An iodine test of a tomato plant leaf revealed that starch was present at 5:00 p.m. on a sunny afternoon in July. When a similar leaf from the same tomato plant was tested with iodine at 6:00 am the next morning, the test indicates that less starch was present in this leaf than in the leaf tested the day before. This reduction in starch content occurred because starch was
- 1. changed directly into proteins
- 2. transported out of the leaves through the guard cells
- 3. transported downward toward the roots through tubes
- 4. changed into simple sugars
