Explanation:

prostate cells usually require testosterone and other androgens to survive. but some prostate cancer cells thrive despite treatments that eliminate androgens. one hypothesis is that estrogen, often considered a female, may be activating genes normally controlled by an androgen in these cancer cells. desribe one or more experiments to test this hypothesis

Answers

One can check for the translation and transcription of genes of interest in the absence of androgens, one can check whether the estrogen is involved in the expression of oncogenic proteins of interest by depleting the estrogen, and one can also examine the existence of estrogen receptor complex in the prostrate cancer cells nuclei.  

• One can check for the translation and transcription of genes of interest in the non-existence of androgens and if these genes are expressed then this suggests that apart from androgens other factors also affect their expression.  

• One can deplete the estrogen from cancer cells and if the involvement of estrogen is there in the expression of oncogenic proteins of interest then its reduction will result in diminished multiplication rates in cancer cells.  

• One can also test the existence of estrogen-receptor complex in the prostate cancer cells nuclei to confirm that estrogen is taking part in the regulation of gene expression.  

Thus, various experiments can be conducted to check that whether the expression of genes controlled by the androgens under normal conditions are affected by the presence of estrogens in prostate cancer cells.

what was the speed of a car that traveled 240 m in 12 s

Answers

Answer:20

Explanation:   Because when you divied 240 by 12 you get 20.

240/12=20

Answer:

20m/s

Explanation:

Speed is equal to distance/time. Since we know that the distance is 240m and the time taken to travel 240m was 12 seconds, we can divide them 240/12 and once we do this we can get our final answer of 20m/s.

Answers

Answer:

3.dominant alleles more frequent than recessive alleles

Explanation:

To achieve hard-Weinberg equilibrium, certain conditions must be made.

These conditions are:

1. There is noo mutation,

2. Existence of random mating,

3. There should be no natural selection

4. There is the infinite population size

5. No migration

Hence, in this case, the correct answer is option 3, which is not a condition to be made for Hard-Weinberg equilibrium

Inversion of DNA sequences within chromosomes is a common process in evolution. The following gene arrangements in a particular chromosome are found in four different species: First sequence: STUVWX Second sequence: UVXTSW Third sequence: UVWSTX Fourth sequence: SWVUTX Assuming that the arrangement in the first sequence is the ancestor/reference arrangement, in what evolutionary order did the four species arise, such that the fewest number of inversions occur between each species (place the first sequence as the earliest species in your ordering)2341

Answers

Answer:

The correct answer is - 1, 4, 3, 2.

Explanation:

It is given that the first sequence represents the earliest or ancestor species therefore, the first sequence would be - STUVWX

After the inversion, the highlighted sequence of the first sequence STUVWX gives rise to the second sequence as:

STUVWX

SWVUTX

Thus the second sequence after Ist inversion would be SWVUTX

2nd inversion, Third sequence:

SWVUTX

UVWSTX

Thus the third sequence after 2nd inversion is UVWSTX

3rd inversion, fourth sequence:

UVWSTX

UVXTSW

Thus, the fourth sequence after 3rd inversion is UVXTSW

brief explain the roles of the following in photosynthesis 1 NADP 2) Ribubose diphostate 3) photosytem 1 ad 2​

Answers

Answer:

1) NADP is the reducing agent produced by the light reactions of photosynthesis and is consumed in the Calvin cycle of photosynthesis and used in many other anabolic reactions in both plants and animals.

3) Photosystems are the functional units for photosynthesis, defined by a particular pigment organization and association patterns, whose work is the absorption and transfer of light energy, which implies transfer of electrons. Physically, photosystems are found in the thylakoid membranes. There are two kinds of photosystems: photosystem I (PSI) and photosystem II 

● PhotosystemSII acts first during the light transformation process in photosynthesis.

● Photosystem1 is an integral membrane protein complex that uses light energy to catalyze the transfer of electrons across the thylakoid membrane from 

plastocyanin to ferredoxin. Ultimately, the electrons that are transferred by carrier NADPH.


During glycolysis, the molecule glucose is broken down into pyruvate. What type of reaction is this?

Answers

Explanation:

Glycolysis is a set of anaerobic reactions, ones that does not need oxygen to be performed. It takes glucose and breaks it down into pyruvate. This has the result of creating two ATP, which can release energy.

Overall, this process creates four ATP, but it uses two ATP early in the reaction. This means that there is a net gain of two ATP.

The overall equation for this pathway is:

1 glucose + 2 ATP ⟶ 2 pyruvate + 2 NADH + 4 ATP + 2 H2O

Glycolysis is a set of anaerobic reactions, ones that does not need oxygen to be performed. It takes glucose and breaks it down into pyruvate. This has the result of creating two ATP, which can release energy.

Overall, this process creates four ATP, but it uses two ATP early in the reaction. This means that there is a net gain of two ATP.

What does glycolysis process?

Glycolysis is the method of breaking down glucose. Glycolysis can take place with or without oxygen. Glycolysis produces two molecules of pyruvate, two molecules of ATP, two molecules of NADH, and two molecules of water.

Glycolysis occurs in the cytoplasm.

Thus, Glycolysis is the method of breaking down glucose. Glycolysis occurs in the cytoplasm.

Answers

Answer:

Centromere

Explanation:

Connects sister chromatids

The structure labelled A in the figure is a centromere.

What is a centromere?

The centromere is a region of the chromosome that is constricted. The centromere plays an important role in the division of cells during both the processes of mitosis and meiosis.

The centromere is simply the region of the chromosome where the spindle fibres attach. Therefore, when the spindle fibres attach to the centromere, they pull the sister chromatics in the opposite directions of the cell during cell division.

Thus, at the end of the cell division, each of the daughter cells gets one-half of the chromosome containing identical DNA. The centromere is thought to be the middle region of the chromosome, even though it is often not in the middle. It is simply the region where the chromosomes are most constricted

The centromere separates the chromosome into the P arm and the Q arm. These are simply the names given to the short arm and the long arm of the human chromosome respectively.

Unfortunately, the economy in which you are operating is experiencing deflation at a rate of 10% per year.After one year, you should be able to sell the building for _.Suppose that owning the building for a year would earn you $5,000. To decide whether or not you will be better off by owning it for one year and then selling it, you sought advice from three different people: (1) Your brother says that you should not buy the building because in one year it will cost you $100,000.
