Answer:
HYPOTHESIS: IF the salinity of the solution decreases, THEN the vegetable mass increases.
Explanation:
Hypothesis, in an experiment, is a testable explanation or prediction made to solve an observed problem or answer a question. It shows how one variable called independent variable affects another variable called dependent variable. It is usually written in the "IF, THEN" format.
In this case, the question states that there is a relationship between vegetable mass and salinity of the solution. This means that the question has been asked that "Why is the vegetable's mass affected by salinity of a solution". Hence, a hypothesis can read:
IF the salinity of the solution decreases, THEN the vegetable mass increases.
The correct answer is Lysosome.
A membrane-bound organelle witnessed in various animal cells and the majority of plant cells is known as the lysosome. They are spherical vesicles, which comprises hydrolytic enzymes that can dissociate various types of biomolecules.
A lysosome exhibits a particular composition, of both its lumenal proteins and membrane proteins. The lysosome functions as the waste disposal system of the cell by digesting undesired substances in the cytoplasm, both from obsolete components within the cell and from external of the cell.
Answer:
Antigens
Explanation:
Antigens can be defined as molecules that can bind to antibodies. Many authors prefer to define it as any substance capable of eliciting a response from the immune system, however there are antigenic substances that react with the antibody but are not able to stimulate its production.
Antigens are usually unknown molecules in the body. Molecules that detach from foreign cells such as bacteria, fungi, protozoa or even viruses can be considered antigens. Toxins released by bacteria are also examples of substances that can bind to antibodies.
When an individual's blood-type alleles have instructions that direct the construction of a specific set of chemicals that protrude from all red blood cells, these chemicals are the antigens.
The common way that scientist use to isolate DNA in order to study it is : Scientists Extract DNA from a part of a cell.
Then, they will break down the fat to isolate the DNA from all cell debris
