Explanation:

The relationship between the termite and bacteria is called mutualism.

Mutualism is the kind of relationship between two organisms in which both organisms benefit from one another.

According to this question, termite stomachs contain bacteria that digest the fiber in wood for the termites. In turn, the bacteria are provided with a hospitable environment to carry out their life processes.

This means that both the termite and bacteria are benefitting from the relationship, hence, is a type of mutualism.

The relationship described between termites and the bacteria in their stomachs is an example of mutualism. So, the correct option is B.

A symbiotic relationship in which both organisms benefit from the interaction is known as mutualism. In this example, the bacteria give the termites the ability to digest the fiber in wood, which they are unable to digest on their own, in return for the bacteria providing the termites a hospitable environment to live and carry out their life activities.

A specific type of mutualism known as "symbiosis," in which the species involved live in close association with one another for extended periods of time, as illustrated by the termite-bacteria mutualism. These kinds of mutualistic connections are prevalent in nature and can involve a wide range of creatures, including microbes, plants, and insects.

Therefore, the correct option is B.

C. energy can neither be created nor destroyed

Explanation:

The law of conservation of mass states that in a chemical reaction mass can neither be created nor destroyed. Similarly, the law of conservation of energy states that the amount of energy in an isolated system is conserved ie. the amount of energy can neither be created nor destroyed, but instead changes form.

mRNA bases are grouped into sets of three, called codons.

Answer:

during this process the nucleic of the male and female gametes are fused in order to create a zygote .known as fertilisation.Gametes contain half the number of chromosomes of all other cells in the organism .Meaning they are haploid .

Cells responsible for fertilisation:

fertilisation is the fusion of the nucleus of a male gamete with the nucleus of a female gamete ,producing a new cell called a zygote

Answer:

Mutations can provide resistance to antibiotics If we were to treat the bacterial population with that specific antibiotic, only the resistant bacteria will be able to multiply; the antibiotic selects for them. These bacteria can now increase in numbers and the end result is a population of mainly resistant bacteria.

Explanation:

Even though mutation is rare in bacteria, it is still important to be concerned about bacteria. The reason is that if any mutation happens that converts the bacteria into antibiotic-resistant bacteria, then this would be harmful.

Mutation is a phenomenon in which a change is seen in an organism's genome. It may be induced by chemical factors, environmental factors, etc. The mutation may be positive or negative.

In a population, evolution is seen due to mutation. It is one of the factors behind evolution. In bacteria, the mutation happens too. If any sort of mutation happens that makes them antibiotic-resistant, then it would be harmful for humans. Humans take antibiotics that destroy harmful bacteria. If these bacteria mutate their genetic constitution and become resistant, a higher dose of antibiotic will be required next time to destroy such harmful bacteria.

Hence, mutations in bacteria are harmful even though they are rare.

Question:

A male cardinal's red color is an example of a trait affected by natural selection. The females of the species choose mates based on the vibrant colors of the males' feathers. If females begin using different criteria than feather color when they choose mates, what would most likely happen to the color of the male cardinals over time?

Answer:

Feather color loses importance in sexual selection and becomes disadvantageous for males. There is a decrease in red color variation among males.

Explanation:

In cardinal species, females choose males to mate according to their vibrant red color. The redder the male is, the better genetic charge it has, and the better choice for mating it becomes.

Red feather color is a trait that reflects the genetic quality of males. So individuals with the most vibrant red color express better capabilities of finding food, competing for resources, competing for males, among others, are the best option to mate and to ensure successful offspring.

The brightest or most vibrant males are in red, the better chances they have to mate and pass their genes to the following generations. So the organism spends energy and resources to produce more vibrant colors to enhance mating chances.

However, if females begin using different criteria than feather color when they choose mates, color production stops making sense. What is even more, it becomes more disadvantageous for males because females do not use color for their choices, males spend energy when producing it, and the redder the males are, the more chances to be predated they have. So basically, males´ feather color loses importance. The selection pressure in males turns to the evolution of another trait. The shade variation of red feathers will decrease over time.

Answer: Due to the strong force of attraction of external objects like meteorites or rocks the outer surface of the moon is affected by the craters.

Explanation:

The asteroids, meteorites, comets, and other space bodies fly around the moon and when they hit the surface of the moon a crater is created as the moon has no atmosphere. Also, the size of the crater is larger than that of the size of the body. The inner surface of the moon also has a crater which is because of volcanic eruptions occurring inside the moon. The volcanic craters are the same as that of the impact so produced. The volcanic eruptions are not much frequent than the exterior objects hitting the moon so more craters are created on the outer backside of the moon.

Answer:

1. The pieces of evidence that support the theory of evolution include the following:

a. Fossil records/evidence

b. DNA of the organisms

c. Comparative anatomy

2. Whales have features that are similar to land mammals, such as the presence of hip bones and the need to breathe air. In this case, the whale fossils indicate that the modern whales that we see today have evolved from the land-dwelling mammals that existed 50 to 70 million years ago.

3. According to Darwin’s theory of evolution through the process of natural selection, the presence of a trait that is observed throughout the timeline of divergence of species is used as evidence that supports the idea that certain organisms share common ancestors.

In this case, comparative anatomy can provide the scientists the evidence that the organisms which share anatomical or structural similarities have common ancestry; hence, supporting the theory of evolution.

Explanation:

Answer:

True

Explanation:

Moving a book so the potential energy of the system decreases is a true statement.

A book's potential energy is reduced when it is moved to a lower shelf. A charge's electric potential energy is decreasing if it is traveling in the direction that it would typically go.

A charge's electric potential energy increases if it is pushed in the opposite direction from how it would ordinarily travel.

Since the potential at the Earth's surface is zero, gravity always has a tendency to draw items toward the planet's center, this causes the potential energy to be reduced.

Therefore moving the book to a lower shell change potential energy, which decreases.
