The answer would be, Fats. Since Triglycerides (3 fatty acids + 1 glycerol) are those lipids which are commonly known as lipids. 

A change in a sequence of DNA bases in a bacterial cell has resulted in a mutation. This mutation has increased the ability of the bacteria to break down and digest organic molecules in the environment. Bacteria with this mutation are better able to find and utilize food sources. According to the theory of natural selection, what is MOST likely to occur in future generations of this bacteria?A)The relative frequency of the mutation will increase as time passes.
B)Because the mutation has changed the DNA of the bacteria, a new species will be formed.
C)Because the mutation is abnormal, the mutation will become more rare with every passing generation.
D)Bacteria with the mutation will increase in number until the food supply is exhausted, causing the bacteria to become extinct.

Answers

The answer is A) The relative frequency of the mutation will increase as time passes. 

In natural selection, genotype variations that will increase the chance of survival and reproduction of some organism are preserved and will be inherited. So, the mutation could not be abnormal, since it helps bacterial survival. Also, the bacteria will not extinct because of this mutation nor the new species will be formed since this is not so big mutation.
This leaves A) as the right answer. The relative frequency of the mutated allele will increase since the more bacteria with the mutation will survive and it will be passed down to the new generation over time.

Asexually reproducing organisms produce offspring that are genetically identical to each other and the parents. What type of cell division are the offspring a product of?

Answers

Answer:

Binary fission.

Explanation:

Binary fission: It is known as the asexual reproduction, in which a single organism formed two independent organisms, and also defined as duplication of organisms. This starts with the replication process of DNA within the cell. Before binary fission mitochondria must have replicates its DNA.

After that, the DNA is separated into ends (alternate) of the single cell. One cell becomes two with the help of plasma membrane turns the cell apart. Then each cell is capable of all the function with fully functioning DNA molecule, and cell becomes independent organisms.

HELP!!!In 3-5 sentences, explain how natural selection is a blessing from God. Remember to
use complete sentences and proper grammar.

Answers

Natural selection is adapting and changing according to the surrounding environment. It is involved in the mechanism of evolution, to explain the diversity of organisms, survival of the fittest, giving rise to new species, etc.

What is the importance of natural selection?

Natural selection leads to speciation, which is the main factor behind the formation of new species.

Reproduction is the crucial factor for naturalselection to occur. It is the mechanism of evolution.

It is the blessing of god for the following listed reasons:

  • It is involved in evolution.
  • It serves for the survival of the fittest, which leads to a healthiergeneration.
  • It also results in speciation, which leads to the formation of newspecies.
  • It is required for maintaining the diversity of the organisms.

Thus, these are some factors that can prove that naturalselection is a blessing from god.

Answer:

Natural selection is a blessing from God because when God created all living things, he made them with their own special look. With their own special look, they will have their own traits to help the survive. Their traits will only get stronger and more visible.

If an animal cell shrinks it was probably placed in a

Answers

Answer:

Hypertonic solution

Explanation:

A solution with higher solute concentration is called as hypertonic solution while the one with less solute concentration is termed as hypotonic solution. Osmotic movement of water occurs from hypotonic to hypertonic solution to balance the concentration of solution. When an animal cell is placed in a hypertonic solution, it loses water through osmosis and shrinks.

An animal cell will shrink if it is placed in a saline/ salty solution (hypertonic solution). The salt will absorb the water from the cell through osmosis.
