What is the relationship between the masses of the objects and the gravitational force
between them?
I foron hotuen the two obiects in this

Answers

Answer:

They are directly proportional

Explanation:

The relationship between the masses of the objects and the gravitational force between them is such that both quantities are directly proportional to one another.

This is based on the Newton's law of universal gravitation.

The law states that "the gravitational force of attraction between two masses is directly proportional to their products and inversely proportional to the square of the distances between them".

So, the gravitational force is directly proportional to the masses of the two objects.

A man and woman are deciding whether to have a child. The genotype of

the man includes a recessive allele for an inherited disease. The genotype of the woman

does not include this allele. Both parents have a normal phenotype. Could the child

inherit the disease? Explain your reasoning

Answers

Answer:

No, the child cannot inherit the disease.

Explanation:

The problem tells you that the man has a recessive allele for an inherited disease, but he has a normal phenotype. This means that the disease is recessive and in order for an individual to have the disease, they must have two recessive copies of the allele. The problem also tells you that the mother has a genotype that does not include this allele. With this information, you can do a punnet cross of BB (mother) x Bb (carrier father), and end up with the following possible genotypes: BB, Bb, BB, Bb. Therefore the child will not have the disease, but there is a 50% chance that the child will be a carrier for the disease.

No, the child cannot inherit the disease.

As the genotype of the man includes a recessive allele for an inherited disease.

What is dominant and recessive allele?

Dominant refers to the relationship between two types of a gene. Individuals receive two types of each gene, known as alleles, from each parent.

If the alleles of a gene are different, one allele will be expressed, it is the dominant gene. The effect of the other allele, called recessive, is masked.

Thus, No, the child cannot inherit the disease.

The HeLa cancer call genome is vastly different from Henrietta’s normal genome. A gene transfer from the human papillomavirus 18 virus (HPV18) to human cervical cells created the original HeLa strain of cancer cells.

a) Describe the type of evidence scientists would need to justify this claim.

b) From this discovery, an HPV vaccination was developed. Without HeLa cells, this would not have been possible. Yet, these cells were taken for research without Mrs. Lack’s knowledge. Evaluate the pros and cons of designating biopsy cells as "free cells," cells that can be used without required patient consent.

Answers

Answer:

a. Sequencing the genome and transcriptome of these cells

b. Pros: these cells can be very useful in research (as in Henrieta case)

Contras: 1. patient's family may have inherited the same genetic defect from their common ancestors, thereby this information might be used for malicious people  

2. Ethical issues  

Explanation:

By using genome sequencing technologies it is possible to determine the nucleotide sequence of the genome (DNA) and their transcriptomic products (i.e., RNAs, especially mRNAs) obtained from a particular cell type. Therefore, these technologies can be used to compare the genome of cancer cells and Henrietta’s normal genome.

HeLa cells have been very useful in pharmaceutical research. These cells have been used in cancer research, in the development of vaccines (e.g., polio vaccine and HPV vaccine), Parkinson's Disease, etc. Moreover, the use of cells without required patient consent may affect the patient’s family by exhibiting information about the genetic conditions of multiple generations of this family, which might be considered unethical and lead to problems associated with the malicious use of this information.

HeLa Cell

It is the first human immortal cell line.

a). The scientist took a tissue sample from a patient named Henrietta Lacks. She was a cervical cancer patient.

Now when the scientist observed the cell sample in the laboratory, they saw that cell was growing indefinitely, i.e. 'immortal'.

So, they named it the HeLa Cell.

Later, the scientist found many copies of HPV-18 (Human Pappiloma Virus-18) in these HeLa cells which is a strain of HPV.

These strains has caused cervical cancer in Henrietta Lacks.

b). The Pros

It could not have claimed if any medical negligence would have occurred.We can overcome the false perception of the patient.The research could be progressed without any interruption from the patient.

   The Cons

If the consent of the patient was not taken then there would have been legal issues as well as ethical issues.Also, the law orders to stop the research without patient's consent.Without the right patent, the commercialization of the cells would begin.

What is the importance of reproduction among living organisms?

There's no science genre so I picked Biology.
Please help me ☹️☹️☹️

Answers

Question 1 Answer
It happens in a short period of time because unlike sexual reproduction it does not involve finding a mate, finding gametes, fertilization and development of an embryo. This make the process more speedy and increases the population of organisms that produce this way at a fast rate.


Question 2 Answer
Asexual reproduction involves only one parent and the offsprings are produced by mitosis. Where as sexual reproduction involves two parents. Gametes are produced in reproductive organs by meiosis.

Off springs of asexual reproduction usually remain close to the parent. This increases the chances of over crowding and competition. Where as in sexual reproduction offsprings are usually dispersed over a large area. This reduces the chances of overcrowding and competition.

Question 3 Answer
Living organisms must produce offsprings in order for their species to survive.
