Explanation:
Magical ability is a dominant trait controlled by two loci. To be able to perform magic, a person would need to carry at least on copy of the dominant allele on each of the two loci. Hermione Granger has magical ability but neither one of her parents does. Which of the following are possible genotypes for Hermione Granger’s parents?
a. AAbb x Abb
b. aaBb x AAbb
c. aaBb x aaBB
d. AaBb x AaBb
e. None of the above
Answer:
b. aaBb x AAbb
Explanation:
According to the information in this question, the trait for magic ability is controlled by two genes, each comprising of two alleles i.e. A,a and B,b. However, to be able to perform magic, a person would need to carry at least one copy of the dominant allele (A and B) on each of the two loci.
Hermione Granger has magical ability but neither one of her parents does. This means that although Hermione can perform magic, none of her parents can. Genetically, it means that Hermione posseses at least one copy of the dominant allele on each of the two loci i.e. her genotype is A_B_.
This is only possible in Hermione if her parents transferred a dominant allele at each loci to her. This means that the possible genotypes for Hermione Granger’s parents are aaBb (no magical ability) x AAbb (no magical ability). See the punnet square attached where the probability of producing offsprings with magical ability is 1/2 or 50%.
If proteins do not have the correct structure, they cannot function properly. Protein misfolding is a cellular malfunction that occurs when proteins do not properly get modified and folded into their correct 3D shape after they are initially synthesized.
Which of these cell structures is most likely responsible for protein misfolding?
NUCLEOUS
LYSOSOME
ENDOPLASMIC RETICULUM
MITOCHONDRIA
Answer:
The correct answer is - ENDOPLASMIC RETICULUM
Explanation:
In the cell, all cell organelle performs a specific function. Protein synthesizes with the help of ribosomes then they are sent to the endoplasmic reticulum for folding the proteins to their correct form or shape before sending them to the Golgi body for packaging.
Protein folding is an important function performed by the ER and must be correctly folded into particular 3-D shapes in order to function correctly and if not correctly folded then degraded by lysosomes.

What is a meiosis and how it is formed
Answer:Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction.
If the DNA triplet read GTC, what amino acid would be brought to the
growing polypeptide/protein?
Answer:

Explanation:
You need to translate the DNA triplet to RNA which becoms CAG. CAG codes for Glutamine. Good luck, hope this was right.
Human blood types have 3 alleles: A, B, and O. A and B are codominant, while o is
recessive to A and B.
If a person has the genotype AO what is their blood type?
a. O
b. B
C. AB
d. A
Answer:
D
Explanation:
A genotype of AO means that the person only has the A antigen, so their blood type is just A. AO and AA have different genotypes but the same blood type.
explain why SARS-COV-2 is classed as a pathogen
Answer:
SARS-CoV-2 is the seventh coronavirus strain known to infect humans and it causes respiratory disease in humans. These viruses infect humans and are currently causing a pandemic in the world.
A pathogen is an infectious organism that causes illness or disease to its host. There are many types of pathogens that infect the body of the host that disrupts the normal physiological process of an organism. SARS CoV2 is also a pathogen as it infects the human body and disrupts its physiology and causes disease.
Most of the improvement in agricultural crop yields has been through inputs: getting more fertilizer to the plant, decreasing weeds, spacing, reducing loss from pests and local environmental changes. But the next big engineering feat will be with the plant molecular pathways themselves, in particular, photosynthesis. The article refers to C3 and C4 plants. What are plant geneticists trying to accomplish
Answer:
It changes the genetic makeup to produce more yielding plants.
Explanation:
Plant geneticists trying to produce a plant which used all the inputs efficiently in order to produce higher yield with the use of low inputs. C3 plants are inefficient plants because they uses resources not efficiently while on the other hand, C4 plants are those which utilizes resources efficiently means more growth by using less inputs or high conversion power so we can say that the Plant geneticists produce a plant by changing their genetic makeup.
Combining your knowledge of rates of diffusion with your knowledge of muscle physiology, explain why it is advantageous for oxidative muscle fibers (which depend on aerobic metabolism to generate ATP) to have smaller diameters compared to glycolytic muscle fibers.
Answer:
To provide quick energy to the muscles.
Explanation:
It is advantageous for oxidative muscle fibers to have smaller diameters compared to glycolytic muscle fibers because these fibers depend on aerobic respiration to provide energy to muscle contractions. This smaller diameter enables the oxidative muscle fiber to move very quickly in order to provide quick energy to the muscles. If their diameters are big so they are unable to provide quick energy in the form of ATP to the muscles for their contractions.
Which of the following statements concerning diffusion and active transport is correct?
A. Active transport requires energy while diffusion does not
B. Diffusion requires energy while active transport does not
C. Both processes require energy
D. Neither diffusion nor active transport requires energy
Answer: A
Explanation:
Active transport requires energy while diffusion does not
Active transport pumps molecules and ions against a concentration gradient. Thus, option A is correct.
What is the main role of active transport?As contrast to assisted diffusion, which carries molecules or ions along a gradient of concentration without the application of energy. An organism occasionally needs to transfer items up or down a gradient of concentration.
In order for cells to acquire molecules or ions from the environment in opposition to the concentration gradient, active transport is a crucial activity.
Because active transport is not passive and requires molecules to move against a concentration gradient, it requires energy.
On the other hand, metabolic products or electrolytes that are substantially loaded into cells might be expelled in opposition to the concentration gradient.
Therefore, Active transport requires energy while diffusion does not.

5. unknown
6. junk
7. inheritance
DNA is an incredibly long molecule that serves many functions in our cells. Some parts of DNA are used for regulating how the cell behaves, while other parts are used to code for proteins. Much of the DNA had unknown functions until recently, and scientist used to call the unknown genes junk DNA. All of the information stored in DNA has been passed between generations through inheritance.
Describe the seasonal differences in the tundra.
Answer:
In the tundra the fall and spring seasons are basically non-existent, leaving only two seasons—winter and summer. ... Summer – The summer season is very short in the arctic tundra (giving plants only 50-60 days to grow each year). The temperature is much warmer and usually ranges somewhere between 3°C and 12°C.
