With only two foods available, natural selection has favored Flock which has grown the most in the
first three generations. Meanwhile, Flock Mhas declined the most because its beak was the least
successful phenotype for the food available.
( it’s Y and X)

Answers

Answer 1

Answer:

IT'S Y AND X

Explanation:

The question says so at the end :)

Answer 2

Flock X declines the most while natural selection has favored Flock Y the most. Hence, X and Y are correct.

What is natural selection?

The process through which organisms adapt and change according to their surrounding is called natural selection. This theory was given by Charles Darwin. Individuals in a habitat are naturally different from each other. Some individuals have better traits to survive.

According to this theory, only those organisms will survive, which can change as their environment change, and can adapt. For example, the evolution of the long neck of giraffes to feed on leaves.

Flock Y has a strong beak for feeding due to which their chances of survival are maximum. While Flock X have a weak beak for feeding due to which their chances of survival are minimal. Therefore, X and Y are correct.

Skin color, fur color, and height are examples of which inheritance pattern?

A. Mendelian inheritance
B. incomplete dominance
C. codominance
D. polygenic inheritance

Answers

Answer:

D

Explanation:

Skin color, fur color, and height are examples of polygenic inheritance. Thus option D is correct.

What is polygenic inheritance?

Polygenic inheritance is defined as a type of heredity where the trait is created by the interactions of many genes, as opposed to monogenic inheritance where the phenotype is created by the expression of just one gene.

When numerous separate genes have an additive or comparable effect on a single quantitative characteristic, this is known as polygenic inheritance.

Multiple gene or multiple factor inheritance are other names for polygenic inheritance.

The some of the characteristics are since epistasis is not at play, the expression of one gene is not obscured by the existence of the other genes. There are no dominant or veiled genes; the gene involved in polygenic inheritance is either contributing or non-contributing.

Thus, skin color, fur color, and height are examples of polygenic inheritance. Thus option D is correct.

What are the correct order of steps of binary fission from first to last?

Answers

Answer:

Explanation:

Step 1-  Replication of DNA

The bacterium uncoils and replicates its chromosome, essentially doubling its content.

Step 2-  Growth of a Cell

After copying the chromosome, the bacterium starts to grow larger in preparation for binary fissions. It is followed by an increase in cytoplasm volume as well as an increase in the number of organelles. Another prominent trait of this stage is that the two strands migrate to opposite poles of the cell.

Step 3-Segregation of DNA

The cell elongates with a septum forming at the middle. The two chromosomes are also separated in this phase.

Step 4- Splitting of Cells

A new cell wall is formed at this phase, and the cell splits at the centre, dividing the parent cell into two new daughter cells. Each of the daughter cells contains a copy of the nuclear materials as necessary organelles.

Binary fission begins with the replication of DNA. The DNA is copied. The cell elongates. The DNA is pulled toward both ends of the cell. A new septum is formed. Cytokinesis occurs. The septum is completed as a cell wall. The cells are divided in two.

The steps of binary fission can also be explained with the help of amoeba as an example.

First, an amoeba divides into two nuclei and replicates. The nuclei divide and migrate to opposite sides of the parent cell. Then, the cell produces proteins and nutrients to prepare for binary fission, in which it divides and forms two daughter cells.

Since you haven't attached the illustration for finding out the amino acid sequence from the mRNA sequence from, I'll explain the general principle for it.

The mRNA represents the code for translation into specific amino acids which will form the protein. A group of three bases, a triplet code, is referred to as a codon. The tRNA is responsible for recognizing the codon and matching the anticodon that will attach to the mRNA and generate the chain of appropriate amino acids.

Which of the following symbiotic relationships is considered parasitic?
A. Tapeworm in an intestinal tract
B. Bees transporting pollen from flowers
C. Pilot fish swimming under sharks
D. Birds eating the insects from the back of a hippopotamus

Answers

Answer:

A. Tapeworm in an intestinal tract.

Explanation:

This symbiotic relationship is parasitic because the tapeworm causes harm to the host. Tapeworms feed off the nutrients the host consumes, thus making the host sick.

Not parasitic:

Bees transport pollen from flowers back to the nest to feed the young bees, but pollinate female flowers as well which keeps the flower population alive.

Pilot fish swim under sharks to keep other prey from eating them, and the shark do not eat eat the pilot fish.

Birds eating the insect of the back of a hippopotamus keep the hippo clean and parasite-free as well as feeding the birds.

The presence of tapeworm in intestinal tract is considered parasitic. Thus, the correct option is A.

Symbiotic relationships refers to the association between two two organisms belonging to different species. There are three types of symbiotic relationships which are mutualism, commensalism and parasitism.

In mutualism, both of the organisms involved are benefited from the relation.

In commensalism, one of the organisms involved is benefited and the other is neither benefited nor harmed from the association.

In parasitism, one of the organisms involved is benefitted and the other one is harmed from the association.

As in the relationship between tapeworm and human, tapeworm is benefited but the human involved is harmed. Thus, it is a parasitic relation.

Thus, the correct option is A.

Tundra is a habitat in which tree growth is hampered by cold temperatures and short growing seasons. Therefore, option (D) is correct.

What is a tundra?

The freezing temperatures and short growing seasons of a tundra biome make it difficult for trees to develop in this sort of ecosystem.



Most of the time, it is cold, but in the summer, it can get quite warm. The winters on the tundra are long, dark, and very cold. For six to ten months of the year, temperatures are below 0 degrees Celsius. Because the temperatures are so low, there is a layer of frost below the surface. This is a layer of frozen ground.

Arctic tundra is found above the Arctic Circle in Alaska, Canada, Russia, Greenland, Iceland, and Scandinavia, or in Antarctica. Alpine tundra are high on mountains where nightly temperatures are below freezing.

Therefore, option (D) is correct.

Answers

Answer:

c

Explanation:

Competition for water is likely to be more important to the cattle than competition for food, shelter, or energy, as these other needs can typically be met through other means. Therefore,option (C) is correct.

Why cattle need water to survive?

Cattle, like all living organisms, require a consistent supply of water in order to survive. In the passage, it is mentioned that the streams in the cattle's area are dry, which means that there may be limited access to water in this area. Cattle, also known as cows or bovines, are large, hoofed mammals that are domesticated for their milk, meat, leather, and other products. They are typically raised on farms or ranches, and are known for their docile and gentle nature. Cattle are herbivores, and are typically fed a diet of grass, hay, and other plant materials

As a result, the cattle may have to compete with one another for access to water, as it is a basic necessity for survival. In this situation, competition for water is likely to be more important to the cattle than competition for food, shelter, or energy, as these other needs can typically be met through other means.
