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.
Selective breeding happens
Answer:
Selective breeding is the process by which humans use animal breeding and plant breeding to selectively develop particular phenotypic traits by choosing which typically animal or plant males and females will sexually reproduce and have offspring together.

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.
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%.

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.
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.

Answer:
1. functions
2. regulating
3. code
4. proteins
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.
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.

describe the benefits to using tissue cultures to study medications used for treating cancer cells
Medications can be tested on cell cultures instead of being injected into patients unnecessarily.
Cancer cells continue to grow in the cultures uncontrollably allowing scientists to test multiple medications on the cancer cells.
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.
A heterozygous white rabbit is crossed with a black rabbit. What is the probability of getting black rabbit offspring?
Answer:
1/2 or 50%
Explanation:
From the illustration, we will logically assume that the white allele is dominant over the black allele. Let us also assume that the white allele is represented by A, the alternate black allele will be a.
The heterozygous white rabbit will have the genotype Aa.
The black rabbit will have the genotype aa.
Crossing the two rabbits together:
Aa x aa
Aa Aa aa aa
1/2 Aa - white color
1/2 aa - black color
Hence, the probability of getting a black rabbit offspring is 1/2 or 50%
