What are the 3
environmental stresses?

Answer:

The correct answer is -

1) point mutation

2) deletion

3) inversion

4) frameshift mutation.

Explanation:

Point mutation or substitution mutation is a genetic mutation that takes place when there is a change in a single base nucleotide, it can be replaced with other nucleotides from a DNA or RNA sequence of an organism's genome.

Deletion is a genetic mutation that occurs when there is a loss of a segment of a chromosome. If the particular segment is responsible for an important protein or gene the offspring have to be with one copy only therefore, it is considered a bad mutation.

When there is a reversal of the segment of a chromosome occurs a change takes place in genetic material which is known as the inversion type of genetic mutation.

If any of the above mutations take place including deletion, inversion, replacement or insertion in one or more nucleotides to make a change in the amino acid sequence from the site of mutation forward is frameshift mutation.

Explanation:

Monocots contain a single cotyledon in their seed and dicots contain two cotyledons. The nutrients in the endosperm of dicots is absorbed by the two cotyledons. Therefore, a tiny endosperm is found inside the dicot seed. However, the main difference between cotyledon and endosperm is in their function during seedling.

What is a macrocolecule?

A biological macromolecule is a very large molecule that is built from smaller biological, or organic, molecules that are linked together by covalent bonds.

Macromolecules are necessary for an organism’s growth and survival

There are four major classes of biological macromolecules. Carbohydrates, Proteins, Fats, and Nucleic acids (DNA and RNA)

What do you notice about the atoms that make up these molecules?

Carbs-They contain carbon, hydrogen, and oxygen and include the sugars, starches, and fibers that are found in grains, fruits, and vegetables.

Carbohydrates are important for brain function, and they provide energy for working muscles and the central nervous system.

Protein- This type of macromolecule can be found in meats, poultry, fish, eggs, dairy products, nuts, and legumes.

Protein is necessary for building and repairing muscle mass, and it helps maintain a healthy immune system.

There are about 20 amino acids,most prevalent in these are carbon, hydrogen, oxygen, nitrogen, and sulfur.

Fats-are used by the body as energy and to store fat-soluble vitamins (vitamins A, D, E and K). They also insulate the body and protect vital organs.

The human body stores excess fat in specialized cells called adipocytes.

consists of two main components—glycerol and fatty acids.

What happens to macromolecules from food during digestion?

Glycolysis can be best explained as a series of chemical reactions that extract energy from glucose. This process occurs in liver cells. At the start of glycolysis, a molecule of glucose (C6H12O6) is trapped and destabilized, or broken down into two three-carbon molecules. These molecules are called pyruvate. The net products of the process are two molecules of ATP—four molecules of ATP are actually produced, but two are used up—and two molecules of NADH. The liver also metabolizes other macromolecules,

If there is not enough carbohydrate intake, how does the body form glucose?

When there is a shortage of fats or carbohydrates, proteins can also yield energy.

Fats typically provide more than half of the body's energy needs.

If not enough protein is provided by the diet, the body starts chewing on muscle cells.

If there is a glucose shortage, how does the body produce energy?

glucose can be made in the liver and kidneys using protein from elsewhere in the body.

What atoms make up sugar molecules, amino acids, and fatty acids?

Sugar molecules - Glucose, Amino Acids - Proteins, Fatty Acids - Fat

Answer:

hypotonic solutions

Explanation:

hope im right

There is a risk of paramecium to swell and burst in hypotonic solutions.

A hypotonic solution is defined as a solution that has a lower solute concentration than any other solution. A solution cannot be hypotonic, isotonic, or hypertonic without the solution of comparison. It is a description of the solute content of one solution with respect to another solution.

If the surrounding solution has a lower solute concentration than the solute concentration inside the cell, the solution is said to be hypotonic. When a cell is exposed to a hypotonic environment, there is an influx of water and this results in swelling of the cell. For example, in hypotonic solutions the paramecium swells and burst in danger.

Thus, there is a risk of paramecium to swell and burst in hypotonic solutions.

Explanation:

DNA is a double stranded molecule. When DNA is copied the two strand of DNA (old strands) separate and new nucleotides match up with the two separated strands. This process creates two identical double stranded DNA molecules are formed. Each DNA molecule contains one strand of the original DNA molecule and one newly synthesized (made) strand.

Answer:

a) (NH₂)₂CO + H₂O ---> CO₂ + 2NH₃

b) The hydrolysis of urea by the urease enzyme generates ammonia which is a weak base. The ammonia thus produced, acts as a  base by accepting the hydrogen ions present in the acidic environment of the stomach. This reactions serves to neutralize stomach acid in order to create a suitable pH environment that the bacterium requires to survive and colonize.

Explanation:

a) Urease catalyzes the hydrolysis of urea into carbon dioxide and ammonia. The equation of the reaction is shown below:

(NH₂)₂CO + H₂O ---> CO₂ + 2NH₃

b) The hydrolysis of urea by the urease enzyme generates ammonia which is a weak base. The ammonia thus produced, acts as a  base by accepting the hydrogen ions present in the acidic environment of the stomach.
