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%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.

Answer:
I am pretty sure the answer is Melting
Explanation:
You have been given three plants: Two have solid black flowers, and one has grey flowers. You cross each black-flowered plant to the grey plant with the following results:
Parents: black #1 X grey F1: 87 solid black, 83 spotted black
Parents: black #2 X grey F1: all black
To try and make sense of these results, you intercross the solid black-flowered F1 plants from cross #2 with the following results in the F2:
132 black
35 spotted black
11 grey
What are the genotypes of the parents, F1 and F2 generations?
Answer:
The correct answer would be -
F1: #1 black flower plant = Aabb and aabb and #2 = AABB and aabb
F2 = AaBb and AaBb
Explanation:
In this cross, it is the case of the dominant epistasis type of inheritance pattern as Gene A masks the expression of gene B but expresses itself only in presence of b or B.
The ratio of the dihybrid cross change in such inheritance from 9: 3: 3: 1 ratio changes to 12: 3: 1.

Answer:hope tht helped
Explanation:
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
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.

How might environmental manipulation of a crop have unexpected consequences? a. The new crop may require more water than the original. b. The crop may harm the environment. c. The yield may be reduced. d. All of the above Please select the best answer from the choices provided
Answer:
D all of the above
Explanation:
just took the test
Environmental manipulation can have both types of consequences - beneficial as well as adverse. At times, these changes can be unexpected too. The correct option is D.
What negative effect does environmental manipulation of a crop have?The crop can have a need for more water as compared to the original if there would be a change in the soil, region or even climate of the crop. An increase in the temperature can affect the availability of water to the crop.
Changes in the soil can result in variation in the availability of minerals required for the growth of plants. This can cause improper health condition of the crop, which will ultimately decrease its yield.
Overuse of fertilizers and pesticides can affect the quality of the soil and also have a negative impact on the crop. It can also be passed on to the consumers of the crop due to bioaccumulation.
Thus, all of the mentioned statements are correct. Hence, the correct option is D.

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.

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
