Explain how embryology can be used as evidence for evolution

Answers

Answer 1

Answer:

the study of the development of the anatomy of an organism to its adult form, provides evidence for evolution as embryo formation in widely-divergent groups of organisms tends to be conserved. ... Another form of evidence of evolution is the convergence of form in organisms that share similar environments.

Cattle live in an area where the streams are dry. For which basic need do these cattle most likely compete?

a food
b shelter
c water
d energy

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.

This illustration shows a strand of mRNA and the complimentary tRNA molecules that can base pair with the mRNA codons. What is the correct sequence of amino acids?

Answers

Answer:

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.

What is it about the structure of the alveolar-capillary unit that makes diffusion possible? Select all that apply.The capillaries are large. The cell wall of the alveoli is thin. Many capillaries surround one alveoli sac. There is always low pressure in the alveolar-capillary unit. The alveolar-capillary unit provides a large surface area.

Answers

Answer:

The most successful option would be: Many capillaries surround a sac.

Explanation:

Although in this question, I wanted to tell you that among all the options that is the most correct, but it is incomplete.

The capillaries that are in the alveolar unit are not only in great numbers to ensure gas diffusion but they are also SINUSOID capillaries where the cells of these capillaries do not have tight cell junctions, and there is a micrespace between cell and cell that forms the capillary wall.

And why is this? Because the greater the permeability of the capillary, the better the process of gas homeostasis or gas exchange at the alveolar level will be favored.

I hope I have completed your question, because it is very important that you know this, they are not simple capillaries that are only increased in number, but their sinusoidal permeable form makes them fulfill a VITAL function for the human being, this does not mean that all the capillaries of the body are like this, do not forget that we are speaking on time of the socket.

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.

ANS 2)n the deep ocean, the predominant driving force is differences in density, caused by salinity and temperature variations (increasing salinity and lowering the temperature of a fluid both increase its density).

The correct answer would be D

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.

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.
