During which of the following processes would carbon most likely be required?
A. Breaking of rocks
B. Generation of electricity
C. Making of glucose
D. Running of cars
I think its C but when I looked the question up to check my answer, someone said they put C and got it wrong. I know we take fossil fuels out of the ground and burn them to create electricity or to make our cars run. and that burning fossil fuels releases carbon dioxide back into the air. And I know that carbon dioxide, water, and light make glucose.
Answer:
D
Explanation:
Answers D
Answer:
Glucose
Explanation:
During photosynthesis, plants take in carbon from the atmosphere so that they can create glucose. During cellular respiration, living things give off carbon as a waste product. This gives the carbon back into the air.

How and why does a DNA molecule replicate itself?
Answer:
DNA makes a copy of itself during cell division. The separation of the two single strands of DNA creates a 'Y' shape called a replication 'fork'. The two separated strands act as templates for making the new strands of DNA.
Explanation:
A: None of the potential offspring would be male, because the potentially male zygote would have two X chromosomes, and the Y chromosome would be ignored.
B: The male offspring would all be red-green color-blind, because of interference from alleles on the Y chromosome.
C: The male offspring would have full-color vision, because of the presence of the extra X chromosome
D: There would be no change to the phenotypes of the possible offspring, because the extra X chromosome would not be active.
Answer: C the male offspring would all be red-green color-blind, because of interference from alleles on the Y chromosomes
Explanation: College board got it correct
The male offspring would all be red-green colour-blind, because of interference from alleles on the Y chromosome. Hence, option B is correct.
What is colour blindness?a diminished capacity to tell some colors apart. Frequently, the condition is hereditary. Medications and specific eye conditions are additional factors. Men are affected more than women.
Inherited color blindness is not treatable. Treating the underlying issue may be helpful if another condition is the cause of color blindness.
The X chromosome is where the genes that might cause red-green color blindness is handed down. Men are more likely than women to have red-green color blindness since it is X-chromosome-inherited. This is due to the fact that males inherit just one X chromosome from their mothers. Hence, option B is correct.

Which of the following describes the mRNA molecule produced from transcription?
The mRNA molecule is made using the coding strand of DNA, which depends on the gene being
transcribed.
O The mRNA molecule is made using the coding strand of DNA and is transcribed in the parallel
direction
The mRNA molecule is complementary to its DNA template, which depends on the gene being
transcribed.
O The mRNA molecule is identical to its DNA template, which depends on the gene being transcribed.
Answer:
The mRNA molecule is complementary to its DNA template, which depends on the gene being transcribed.
Explanation:
The process of the formation of RNA from DNA is called transcription.
Messenger RNA (mRNA) is a single-stranded RNA molecule that is complementary to its DNA template as the enzyme, RNA polymerase matches the complementary bases to the original DNA strand and then initiates the process of RNA synthesis. Once the strand gets completed, the process got terminated.
Hence, the correct answer is "The mRNA molecule is complementary to its DNA template, which depends on the gene being transcribed."

How can we test for density?
Answer:
Using a vernier caliper or ruler, measure the length, depth and width of the object in centimeters. Multiply these three measurements to find the volume in cubic centimeters. Divide the object's mass by its volume to determine its density. Density is expressed in grams per cubic centimeter or grams per milliliter.

Answer:
I am not sure but the answer must be C
A)x-linked
B)No answer text provided
C)recessive
D)dominant
Answer:
D)dominant
Explanation:
In humans, dimples (D) are dominant over no dimples (d). Curly hair (A) is dominant over
straight hair (a). Paul, who is heterozygous for dimples and curly hair, marries Jane, who
has curly hair but does not have dimples. Jane's mother had straight hair, but her father had
curly hair. Paul and Jane had a child named Peter, who had curly hair but did not have
dimples.
Answer:
1. ddaa
2. DdAa
3. One from each parent
4. False
5. 0.25
6. 0.25
7. 0.25
8. 0.5
Explanation:
The remaining part of the question is
1. What is Jane's genotype?
2. What is Paul’s genotype?
3. Where did Jane get her gene for curly hair? From her mother or father?
4. True or False: Jane's mother was heterozygous for curly hair?
5. What fraction of Paul and Jane's children should have curly hair and dimples?
6. What fraction of their children would have straight hair and no dimples?
7. What fraction should have dimples but not curly hair?
8. What is the probability of getting any offspring with dimples
Solution
1. Genotype of Jane's mother -ddaa
2. Genotype of Paul (heterozygous for dimples and curly hair) – DdAa
3. One “a” gene from mother (whose genotype for hair was aa) and second “a”gene from father (whose genotype was Aa)
4. False. She was having straight hair
5. Offspring of Paul and Jane
DdAa (4), Ddaa (4), ddAa(4) and ddaa (4)
4 out of 16 offspring will have curly hair and dimples = 0.25
6. ddaa, 4/16 = 0.25
7. Ddaa , 4/16 = 0.25
8. Ddaa, DdAa, 8/16 = 0.5
Explain how the discoveries by Rosalind Franklin
helped Watson and Crick build an accurate
model of DNA.
Answer:
In 1951 Franklin joined the Biophysical Laboratory at King’s College, London, as a research fellow. There she applied X-ray diffraction methods to the study of DNA. When she began her research at King’s College, very little was known about the chemical makeup or structure of DNA. However, she soon discovered the density of DNA and, more importantly, established that the molecule existed in a helical conformation. Her work to make clearer X-ray patterns of DNA molecules laid the foundation for James Watson and Francis Crick to suggest in 1953 that the structure of DNA is a double-helix polymer, a spiral consisting of two DNA strands wound around each other.

yes.....................
Answer:
It lies on your perspective

If you clone a human because that is the perfect human, or you genetic engineer a human to make the perfect human, society will benefit, but will the clone/engineered human benefit? As I already said, it is all about perspective.
what were the early plants called?
Explanation:
The oldest fossil evidence of seed plants is of Late Devonian age, and they appear to have evolved out of an earlier group known as the progymnosperms. These early seed plants ranged from trees to small, rambling shrubs; like most early progymnosperms, they were woody plants with fern-like foliage.

using what have you learnt about the effect of concentration gradient and surface area to volume ratio, explain the adaptations of a leaf for photosynthesis
Answer:
Leaves have an increased surface area in order to increase light-harvesting and they are thin in order to increase the diffusion rate
Explanation:
Leaves have several adaptations to increase the photosynthesis rate. In the first place, leaves have a large surface area to increase light-harvesting and thus also increase photosynthetic energy conversion. Moreover, leaves are sufficiently thin to increase the gas exchange surface area, i.e., the entry of carbon dioxide (CO2) and the exit of oxygen from photosynthesis, which move by diffusion through stomata.
