What are the roles of colorists?

A colorist is a film industry professional who creates a visual color story for a production. In the post-production stage of the film making process, a colorist can use color editing software to add the desired hues, tones and color palates to an edited film.

They also work closely with editors to ensure they use similar software. Colorists have specific software package requirements because most colorists use Adobe products, specifically After Effects and Premiere Pro.

A Colorist is responsible for designing the color scheme of a film in order to achieve a specific mood or visual style. Colorists work closely with a film's director and director of photography to determine what color palette will best serve the story.

What two air pollutants are associated with the formation of acid rain?

Answers

Answer:

Acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. These substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.

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.

Students are asked to pair a plant structure to its physiological function as well as give evidence for why

that structure is important for the process they describe.

• Shantal: The cambium are important for photosynthesis because they allow water into the plant

which is needed as a reactant for photosynthesis.

• Jamil: The phloem is needed for cellular respiration as it transports the carbon dioxide to the leaves

in order to perform cellular respiration.

• Enrique: The guard cells are needed during food production because they regulate how much water

the plant retains or loses during glycolysis.

• Anne: The seeds of the plant are needed for reproductive purposes and they can be dispersed or

spread out over a large area.

Which student correctly described a plant structure, its physiological function, and gave appropriate

evidence?

O Shantal

O Jamil

O Enrique

O Anne

Answers

Answer:

Anne

Explanation:

The only student that correctly described a plant structure, its physiological functions, and gave appropriate evidence is Anne.

The seeds of plants are propagules and, depending on the kind of seed, can be dispersed over a large area from their parent plants.

The phloem of a plant is primarily concerned with the conduction of synthesized food around the body of the plant from the source of production. Hence, Jamil's description that the phloem is needed for cellular respiration as it transports the carbon dioxide to the leaves was inaccurate.

The guard cells control the rate of evapotranspiration of water from the plant but have nothing to do with the breakdown of glucose, also known as glycolysis. Thus, Enrique's assertion was also inaccurate.

Give reasons why asexual reproduction produces more offspring in a short period of time.

Differentiate asexual from sexual reproduction.

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.
