Which property of matter is useful for holding papers and photos on refrigerator doors?
Answer:
Magnetism
Explanation:
The refrigerator doors are made of metal, and we use magnets to hold papers and photos on their surfaces. Magnets attract metals such as iron, cobalt, nickel, etc. That is due to the physical property of matter called magnetism, which is related to the attraction force generated by a magnetic field.

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."

Give an example of a sports performer that would require a high level of CV endurance.
Answer:
Cardiovascular endurance is the ability to exercise without becoming overly tired because your heart, lungs and blood vessels are healthy. Exercise examples include walking, jogging, cycling, dancing, running and bike riding. Distance swimming is also a good cardiovascular endurance exercise.
Fruit color in a particular plant is controlled by a set of three quantitative traits that work in an equal and additive manner. Each trait has two alleles (i.e., A and a); each allele represented by a capital letter produces one dose of yellow pigment, while alleles represented with lower case letters do not produce any pigment at all. How many different shades of yellow fruit color are there
Answer:
7
Explanation:
The number of distinct shades of fruit color would be 7. It is given that the color is dominated by a group of three QTL(quantitative traits) with each trait having two alleles(A,a). Out of these two alleles, one represented by a capital letter(A) generates a single dose of yellow pigment while the latter represented by a smaller case letter(a) does not generate any pigment. Since there is no environmental effect, the number of various yellow shades would be 7 through the combinations of yellow and colorless pigments(A/a, A/a, A/a, A).
How does the haemoglobin provide the body with energy ?
Answer:
Hemoglobin transfers oxygen from the lung to the muscles, brain, and other organs, and also helps the body to convert carbohydrates and fat into energy.

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.

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 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.

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.
