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.
Answer:
Explanation:
Gametes are sex cells, such as the egg and sperm. They are used in sexual reproduction to produce offspring.
The sex cells are produced during meiosis. The DNA or genetic material is replicated, then the cells divide twice. After this, four haploid cells are produced with <u>half of the genetic material</u>. For example, human body cells have 46 chromosomes but sex cells have 23 chromosomes.
They contain half the genetic material for an important reason. During fertilization, an egg and a sperm fuse. Each one contributes half of the genetic material from the mother or father to create one complete set for the offspring.
Gametes have <u>half the number of chromosomes in body cells</u> and <u>choice A </u> is correct.

An organism that ferments glucose via the mixed acid fermentation pathway will be<u> acidic methyl red.</u>
<u />
- As part of the IMViC testing, Methyl Red (MR) and Voges-Proskauer (VP) broth is utilized as the medium in which both the Methyl Red and Voges-Prosakuer tests can be conducted.
- It is a straightforward broth made up of dextrose or glucose, buffers, and peptone.
- Different bacteria use various metabolic processes to convert dextrose and glucose to pyruvate. Some of these pathways result in the production of unstable acidic chemicals that quickly transform into neutral molecules.
- The butylene glycol route is used by some species, and it results in the neutral end products acetoin and 2,3-butanediol.
- The mixed acid pathway is used by other organisms and results in the production of acids including lactic, acetic, and formic acid.
- The acidity of these final products is stable and will not change.
