Answers

I believe the answer is copepods

Sand eels represent the trophic level containing approximately 1% of the initial amount of solar energy acquired by phytoplankton.

What is the food chain?

The food chain is an ecological diagram used to represent the connections between different trophic levels.

In the food chain, energy flows from producers to primary consumers and so on.

It has been shown that approximately 90% of energy is lost in the form of heat for each trophic level.

In conclusion, sand eels represent the trophic level containing approximately 1% of the initial amount of solar energy acquired by phytoplankton.

How do you suppose changes in DNA lead to speciation

Answers

Answer:

The correct answer is - change in DNA is called mutation which is essential for evolution including speciation.

Explanation:

A mutation is a change in the genetic or hereditary material which is DNA. A mutation is the main reason behind the evolution of the organism or species and speciation can be led by evolution, which takes place by results in the accumulation of many small changes in DNA or genetic changes in a population over a long period of time.

Mutations that change in DNA are required for the evolution process they are the raw material of genetic variation. without changes in hereditary material, there is no speciation or evolution possible.

5 5. Normally, the temperature inside the scrotum is slightly lower than normal body temperature. What do you predict would happen if the temperature inside the scrotum were a few degrees higher than normal body temperature instead? A. Sperm would not be able to travel through the vas deferens. B. Sperm would be stored in the epididymis rather than in the testes. c. Sperm would not be able to develop properly. D. The rate of sperm production would increase,​

Answers

Answer:

C. Sperm would not be able to develop properly.

Explanation:

There is an optimum temperature where sperm production is at its best. An increase or decrease in temperature may affect the quality and quantity of the sperm.

If the temperature inside the "sc-rotum" raises by few degree than normal body temperature, than the "sp-erm" would not be able to develop properly.

What is the function of "sc-rotum"?

A pouch, which is suspended from the groin, and comprising the "tes-tes" and some of the male "s-ex" accessory ducts is known as the "sc-rotum". The prime function of the "sc-rotum" is to maintain the temperature essential for the process of "sper-matogenesis", that is, by situating the testes external of the body cavity.

Within the human "sc-rotum", the temperature is 3.1 degree C lesser than the usual temperature of the body. In case, if the temperature elevates of the "sc-rotum", the degeneration of the germinal epithelium will take place, which will eventually result in sterility. Therefore, for the production of sperms within the testes, a lower temperature is needed, otherwise the development of the "sp-erm" will not take place appropriately.

Thus, the correct answer is option C.

Which of the following is an example of a phenotype (select all that apply)?
Group of answer choices

Brown Hair

GG

RR'

Physical trait

Answers

Answer:

brown hair and physical trait

An example of phenotypes are brown hair and physical trait. Therefore, option A and D are correct.

What is phenotype ?

A set of an organism's observable qualities or characteristics is known as its phenotype. The phrase refers to an organism's morphology, or its physical form and structure, as well as its physiological and biochemical characteristics, behavior, and the outcomes of that behavior.

We examine the alleles of the parent organisms and predict how frequently the offspring will exhibit those genes to determine a phenotypic ratio. Most of the time, we are aware of the alleles' expression and appearance.

An observable characteristic is simply referred to as a "phenotype." Pheno, which has the same root as the term "phenomenon," simply means "observe." It can therefore relate to anything from a common characteristic, like height or hair color, to a visible type of organism.

Thus, option D is correct.
