Answer:
d.The transferred traits were heritable.
Explanation:
Griffith's experiments with S. pneumoniae were significant because they showed that traits could be transferred from one organism to another and these transferred traits are known to be as heritable traits. In another experiment carried out by Hershey and Chase experiment it was confirmed by the results that DNA is actually the hereditary material not the protein.
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

Answer:
The amphipathic property of the phospholipids that constitute the membrane
Explanation:
It seems like a options-based answer so it would be better if they were included here but basically, each of those phospholipid molecules has two parts with antagonistic reactions towards water.
The head is polar or hydrophilic, wich means it can be sorrounded by water. The tail, is apolar or hydrophobic which means it is repelled by water.
The interior and exterior of the cell is contain water-based substances, that's why the heads of the phospholipids are oriented like that with the tails protected inside the membrane.
This double layer structure has a fundamental role in the fluid property of the cell membrane from which derive most of it's functions.
Answer;
They have revealed new information about cell structure and processes.
Explanation;
-The Cell Theory states that, All living things are made up of cells, Cells are the basic units of structure and function in living things, and that new cells are produced from existing cells.
-Most microscopes use lenses to magnify the image of an object by focusing light or electrons.
-The Invention of the Microscope helped the development of the cell theory because it allowed the scientists to actually discover that everything was made up of cells, and what cells do to come up with that theory. If the scientists did not see that cells existed, they could not have observed the cells easily and they would not be able to construct the cell theory.
