Answer:

The correct answer is C.They help in reproduction , antibiotic resistance, virulence and competition with other bacteria

Explanation:

Plasmids are the small, single circular DNA molecule that is different from the chromosomal DNA of bacteria. These plasmids can replicate independently from the chromosomal DNA. Plasmids are naturally found in bacteria.  

These plasmids contain some extra genes like antibiotic-resistant genes that provide bacteria an advantage in a competition over bacteria that do not have plasmid with antibiotic-resistant genes because when antibiotic is used against these bacteria the bacteria having antibiotic-resistant gene will survive.

Plasmid also code for virulence factors in bacteria like toxins, adhesin proteins, etc. Therefore the right answer is C.

A scientist investigated whether giving plants different quantities of magnesium affected their growth. He
liberstina [14]

The hypothesis that the scientist could test in his investigation is as follows: IF plants are given more than 2.0mg of magnesium, THEN their growth will be negatively affected.

<h3>What is an hypothesis?</h3>

Hypothesis is a tentative conjecture explaining an observation, phenomenon or scientific problem that can be tested by further observation, investigation and/or experimentation.

An hypothesis is commonly referred to as an educated guess because it tends to provide a temporary explanation for a phenomenon.

According to this question, a scientist investigated whether giving plants different quantities of magnesium affected their growth. He measured growth by counting the number of new leaves produced.

The hypothesis of the scientist regarding the above experiment could be as follows: IF plants are given more than 2.0mg of magnesium, THEN their growth will be negatively affected.

1. How many different phenotypes are possible in the offspring of two parents with genotypes AA and aa, where A is the dominant
Stolb23 [73]
For question number 1, there is one phenotype only with homozygous allele which are recessive and dominant of both parents. For question number 2, the answer is letter B. plants with both red and blue flowers because it is codominant so the trait will express both alleles. For question number 3, the answer is letter C. four genetically identical cells because it is from two daughter cells which undergo meiosis that results into 4 identical cells that are needed for somatic cells in our body. For question number 4, the answer is the leading strand is copied in the 5’ to 3’ direction and the lagging strand is copied in the 3’ to 5 because it is based in the ends of each nucleotides that is carrying the genes. For question number 5, the answer is gene regulation which is used by cells to increase of decrease specific gene products or RNA.

What happens if a protein-digesting enzyme is mixed with starch solution?
Pie

Answer: it produce fat as it is base and starch is acidic

Explanation:

it produce fat as it is base and starch is acidic

These polypeptides then move into your small intestine, where digestion will be completed by additional enzymes.

Pepsin is an enzyme in the stomach that breaks down proteins into smaller amino acids. It is produced in the chief cells of the stomach lining and is one of the main digestive enzymes in the digestive systems of humans and many other animals, where it helps digest the proteins in food.

Hope it helps
