True or False: Food Webs are generally more accurate and detailed models of an ecosystem than Food Chains.

Answers

Answer:

True

Explanation:

They have more options and possible ways

Answer:

true,

The food web provides a better model of an ecosystem because the food web is a model between MANY different consumers and producers in an ecosystem. While the food chain is a model for just one consumer and producer. ... Because energy is lost as it moves from producers to consumers, the bottom level is the largest.

1) In yeast signal transduction, a yeast cell releases a mating factor which
A) acts back on the same cell that secreted the mating factor, changing its development
B) passes through the membranes of neighboring cells, binds to DNA, and initiates transcription
C) binds to receptors on the membranes of other types of yeast cells
D) diffuses through the membranes of distant cells, causing them to produce factors that initiate
long-distance migrations

Answers

I think it is A it acts back on the same cell

In yeast signal transduction, a yeast cell releases a mating factor that diffuses through the membranes of distant cells, causing them to produce factors that initiate long-distance migrations. Thus, the correct option for this question is D.

What is the mechanism of reproduction in yeast?

The mechanism of reproduction is yeast is processed through the process of budding which is a type of asexual reproduction. In this mechanism, A bud is a tiny protrusion from the parent cell that pinches off and produces a new individual when it reaches maturity.

Yeast is a single-celled organism that does not have complexity in its process and functions. So, this organism performs its mechanism of reproduction and other functions through the process of diffusion.

Therefore, in yeast signal transduction, a yeast cell releases a mating factor that diffuses through the membranes of distant cells, causing them to produce factors that initiate long-distance migrations. Thus, the correct option for this question is D.

The cell cycle has a regular system of checks and balances that prevents damaged or mutated cells from proceeding to the next phase. One way an organism deals with the problems is to kill the damaged cell before it passes on the problem to its daughter cells. This is a normal process called apoptosis.

a. True
b. Fale

Answers

Answer:

A. True

Explanation:

Apoptosis is a normal cellular process in which the cell inherently programs the death of a mutated or damaged cell without affecting the healthy condition of the other surrounding cells by proliferating.

Apoptosis is a system of checks and balances that the cell uses to prevent damaged or mutated cells from proceeding to the next phase in the cell cycle. This curbs or prevent the damaged cell from passing on the problem to its daughter cells. Hence, according to this question, it is TRUE.

Fifty years ago, bed bugs were nearly eliminated in the United States by using of pesticides like DDT. Today bed bugs are back in beds and theaters. DDT is no longer used due to environmental issues. Pyrethrums are currently the top choice for bed bug infestations. Pyrethrums are especially useful to us because they generally have a stronger effect on bugs than on humans and animals.

Some bed bugs had mutations in their genetic code which allowed them to survive the chemical pesticide and they produced chemically resistant offspring. How can this be explained?

Question 5 options:

bed bugs chose other bugs to partner with who had the mutation


mutations involved in the genetic variation of the bugs were chosen by them

Black mice and tan mice are native species that are observed in a particular region. Human habitation in the region caused an invasive mouse species to enter the region. These mice are brown and share the same food requirements as black mice. Tan mice have different food requirements. How will this change affect the food web in the region? A. The availability of food resources for black mice and brown mice will decrease. B. The population of tan mice will decrease. C. The black mice and tan mice will compete for food resources. D. The tan mice and brown mice will compete for food resources.

Answers

Answer:

A

Explanation:

The correct answer would be that the availability of food resources for black mice and brown mice will decrease.

Since the food requirements of the black mice are the same as that of the invasive brown mice, the available food supply that used to be only for the black mice would now be shared by the two strains of mice. Hence, the available food for the two groups of mice will naturally decrease.

There is no sufficient information to conclude that the population of tan mice will decrease, hence, option B is incorrect.

The black mice and tan mice have different food requirements going by the information available in the illustration, hence, both cannot compete for food resources. Option C is, therefore, incorrect. In the same vein, option D is incorrect because the tan mice have different food requirements from the brown mice.

The only correct option is A.

If a strand of DNA has 17% T,what percent will
be G? C? A?

Answers

Answer:

If a DNA strand has 17% Thymine (T) the percentage of the other nitrogenous bases will be 33% of Guanine (G), 33% of Cytosine (C) and 17% of Adenine (A), according to Chargaff's law.

Explanation:

The percentage of nitrogenous bass in a DNA strand can be established by knowing the percentage of one of the bases present in the molecule, in this case knowing that Thymine corresponds to 17% of bases.

DNA has the nitrogenous bases adenine (A), guanine (G), thymine (T) and cytosine (C).  The bases of one chain are matched with the bases of another, according to the complementarity of the nitrogenous bases, where:

Adenine is complemented with thymine A=TGuanine is complemented by cytosine G≡C

According to this, DNA molecule there is as much T as A, and an equal amount of G and C, and the percentages of nitrogenous bases can be calculated according to Chargaff's rule.

Chargaff deduced that in a DNA molecule the ratio of purine:pyrimidine is 1:1, so there must be the same amount of thymine as adenine and a similar amount of guanine for the cytosine, according to the complementarity of the bases.

Calculating the percentages, according to the law of the base pair, if in a DNA chain there is 17% of T, in the molecule there is:

A =          17 %C =          33%T =           17%G =          33%Total ..... 100%
