Answer:
The skier stops at 2 meters eastward
Explanation: The skier first goes 54 meters east. Then goes back west 68 meters. (54 - 68 = -14) Then the skier goes back 16 meters east. (-14 + 16 = 2)

Identify the 2 constructive processes from the list below.
A) A river wears away the land creating a canyon.
B) Over time a mountains top becomes less jagged and more rounded.
C) A volcano erupts and lava flows down its sides.
D) Silt is deposited at the mouth of a river.
Answer:
C, D.
Explanation:
C: The flowing lava creates extra rock. For example, entire islands are formed via this process of volcanos erupting, lava cooling, repeat.
D: Silt from erosion (erosion itself is considered destructive, but the resulting silt can turn into something constructive.) can build up entire mounds or mountains over time.
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.
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.Learn More :

Most important of all the alkaline metals. It reacts quickly with water. Snow and ice too.
What is an observation? What do you use to make an observation?
Answer: we can make observations directly by seeing, feeling, hearing, and smelling, but we can also extend and refine our basic senses with tools: thermometers, microscopes, telescopes, radar, radiation sensors, X-ray crystallography, mass spectroscopy, etc. And these tools do a better job of observing than we can!
what is DNA labeled a double helix
Answer:
The double helix is a description of the molecular shape of a double-stranded DNA molecule. ... Each DNA strand within the double helix is a long, linear molecule made of smaller units called nucleotides that form a chain.
Answer:
Explanation:
The double helix describes the appearance of double-stranded DNA, which is composed of two linear strands that run opposite to each other, or anti-parallel, and twist together. Each DNA strand within the double helix is a long, linear molecule made of smaller units called nucleotides that form a chain.

DNA, the Code of Life
DNA is a complex, long-chained molecule that encodes the genetic characteristics of a living organism.
Bases are the part of DNA that stores information and gives DNA the ability to encode phenotype, a person's visible traits. Adenine and guanine are purine bases. These are structures composed of a 5-sided and 6-sided ring.

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
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.
Which two animals are able to generate internal heat to maintain their body temperature in a coid environment

What would be the main problem if every trait followed a blending pattern?
Answer:
Blending inheritance leads to the averaging out of every characteristic, which as the engineer Fleming Jenkin pointed out, would make natural selection impossible if blending were the mechanism of inheritance.

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

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.
