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.
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.

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
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.

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
bed bugs chose other bugs to partner with who had no mutations

If a strand of DNA has 17% T,what percent will
be G? C? A?
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≡CAccording 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%If anyone knows this please let me know and explain??
