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
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
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.

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

Explanation:
How did diffusion of the perfume change with an increase of concentration
Answer:
Explanation:
Diffusion is trigger by concentration differences.
When perfume is sprayed in the room, the molecules of the perform come in contact with the air molecules and tend to mix well with air molecules, this molecules then spread and move from area of lower concentration to an area of higher concentration. Because the molecules are in constant motion, they move to area where there is high concentration.

Phenotype of offspring:—-?
Genotypes of offspring:—-?
Lol I need help
Answer:
The correct answer is -
The phenotype of offspring (first cross or F1): 100% tall
The genotype of offspring (first cross or F1 - 100% Tt or heterozygous)
The phenotype of offspring in F2 (F1 × F1) - 3:1 (3 tall: 1 dwarf)
The genotype of offspring in F2 (F1 × F1) - 1:2:1 (One dominant tall: two heterozygous tall: one dwarf)
Explanation:
In this experiment of Mendel, Mendel selected the pea plant as it has various characters, short life span, and easy to breed. For this, he used two true breed lines, tall plants that had dominant allele TT and dwarf plant tt (recessive). In presence of the dominant allele, recessive alleles do not show their characteristics and only express if both alleles are recessive.
In the first cross of TT and tt
Gametes: T and t
offspring: Tt
the offsprings are all tall and heterozygous which means one dominant and one recessive allele.
second cross or F1 × F1
Tt × Tt
gametes: T, t and T, t
offspring: TT, Tt, Tt, tt
Thus,
The phenotype of offspring (first cross or F1): 100% tall
The genotype of offspring (first cross or F1 - 100% Tt or heterozygous)
The phenotype of offspring in F2 (F1 × F1) - 3:1 (3 tall: 1 dwarf)
The genotype of offspring in F2 (F1 × F1) - 1:2:1 (One dominant tall: two heterozygous tall: one dwarf)

What are the structural differences between a cockroach and a grasshopper?
Cockroaches have legs for crawling on walls and ceilings, but grasshoppers have legs for jumping. Some cockroaches have wings for flying, but most others don't. Grasshoppers have wings for making a sound, whether it's to attract a mate or to just be annoying. Grasshoppers have a body that is split into multiple segments (more than just one), while cockroaches have only like 2 body segments. Cockroaches have barbs on their legs for a sense of touch, while grasshoppers don't. The legs of a cockroach are very sensitive though. Cockroaches can survive a nuclear explosions because the rads don't affect them. But the heat from the nuclear blast will certainly kill a human, as well as a cockroach if exposed. Obviously, grasshoppers couldn't survive a nuclear explosion. The only down side to roaches surviving a nuclear explosion is them turning into radroaches, like in the Fallout game series from the game developing company, Bethesda Game Studios! If there were a nuclear explosion, then the roaches would mutate into human head sized roaches that can actually attack a human! (this is just a theory, not scientifically proven, lol)

PLEASE HELP! (c) Complete the table to represent the relationship between volume and surface area of a spherical structure surrounded by a membrane.
Answer/Explanation:
Recall:
Volume of a sphere = ⁴/3πr³
Surface Area = 4πr²
✔️For radius (r) = 1 mm:
Volume = ⁴/3 × π × 1³ = 4.19 mm³
Surface Area = 4 × π × 1² = 12.57 mm²
Ratio of volume to surface area = 4.19 : 12.57 = 1:3
✔️For radius (r) = 3 mm:
Volume = ⁴/3 × π × 3³ = 113.1 mm³
Surface Area = 4 × π × 3² = 113.1 mm²
Ratio of volume to surface area = 113.1 : 113.1 = 1:1

5. What is symbolic about the Dragon’s Cup and why was it added to the movie?
Beowulf and Grendel's mother formed an alliance, and the dragon's cup served as a sign of their understanding. It is appropriate for the film, and perhaps alludes to Beowulf and the dragon's conflict.
What is symbolic about the Dragon’s Cup?The dragon's hoard of treasure eloquently symbolizes both, the flimsiness of human desires and the changeability of time. The wealth in the dragon's tomb is plentiful, but no one can use it.
Gardner uses the dragon as a symbol for life's sorrow—the kind of misery that might result in the gloomy beliefs (and disgusting social behaviors) he eventually shares with Grendel.
Beowulf grabs a knife from his belt and stabs the dragon's flank desperately. The fatal strike causes the writhing serpent to wither.
But as soon as Beowulf achieves victory, the cut on his neck starts to enlarge and burn. He understands that the venom from the dragon bite is killing him.
Therefore, flimsiness of human desires and the changeability of time symbolic about the Dragon’s Cup.
