A new sunscreen has been developed that is supposed to be more effective at preventing sunburn. 30 participants spray one arm with the new formula and spray the other arm with the leading formula. After 4 hours in the sun, their skin is evaluated for any redness.What is the Independent Variable?a. the 30 arms with the old formulab. the 30 arms with the new formulac. Amount of rednessd. Type of sunscreene. the 15 arms with the new formula
Answer:
The correct answer is : b. the 30 arms with the new formula
Explanation:
Independent variable is a variable that is present in the experiment and research experimenting about and do not depend on any other variable. In this experiment the researcher is experimenting about the new sunscreen and its effect on the people.
In this experiment the 30 arms with new formula is independent variable that would change or altered the dependent variable.
Thus, the correct answer is : b. the 30 arms with the new formula

The human stomach secretes an enzyme known as pepsin. This enzyme breaks down proteins into smaller chemical molecules called peptides. If pepsin was mixed in a laboratory with sugar molecules like glucose, what is the MOST LIKELY result?
Question 13 options:
Pepsin will break down glucose molecules into simpler substances.
Pepsin will react with glucose only if the necessary RNA molecules are present.
Pepsin will probably NOT react with the sugar glucose since it is an enzyme that breaks down proteins.
Pepsin will probably NOT react with glucose since the activity of enzymes is limited to the human body.
Answer:
3rd
Explanation:
pepsin cannot possibly catalyze a reaction for a molecule it has not been shaped to do for.

What is the role of transfer dna
Answer:
The transfer DNA (abbreviated T-DNA) is the transferred DNA of the tumor-inducing (Ti) plasmid of some species of bacteria such as Agrobacterium tumefaciens and Agrobacterium rhizogenes(actually an Ri plasmid). The T-DNA is transferred from bacterium into the host plant's nuclear DNA genome.

All of the variables that are kept the same between the experimental
group and control group in an experiment are called
A. independent variables
B. dependent variables
C. experimental variables
D. controlled variables
Answer:
controlled :variables
An experimental design includes the independent, dependent, and controlled variables. The variables that are kept constant are called controlled variables. Thus, option D is correct.
What are controlled variables?Controlled variables are part of scientific experimentation that are kept constant and remain unchanged through the research and experiment. It is important to control some variables as they might limit and influence the other variables.
They are the same in the experimental group and control group to establish the relationship between the dependent and the independent variables. They are kept at the same rate throughout the groups. For example humidity, temperature, light, etc.
Therefore, in option D. the controlled variables are kept the same in the test and control groups.

what is the difference between abiotic and biotic
Answer:
Abiotic: Anything that is non-living or doesn't contain carbon. Biotic is any organism that contains carbon. Abiotic would be a rock, and Biotic would be bacteria or algae.
Answer:
The biotic factor or biotic component is the living organism that shapes an ecosystem. Abiotic factors or abiotic components of an ecosystem are the non-living physical and chemical composition of nature. Biotic factors depend on abiotic factors for their survival and growth

What sea is located at 17.06 Lat 64.34 Lng?
Answer:
The correct answer is - Arabian sea.
Explanation:
Longitude and latitude coordinates are the geographical position of a place present on the earth. Longitude coordinates tell the exact east west point on the earth surface while Latitude coordinates tells the exact north south location of a point on the surface of the earth.
The degree decimal in the question is 17.06 latitude and 64.34 longitude which is the position of the Arabian sea on the globe.
Thus, the correct answer is : Arabian sea.
Paul Snelgrove: A census of the ocean Both in Unit 1 and in Snelgrove’s talk, emphasis is placed on the importance and massiveness of the world’s oceans. Identify some of the facts from both the unit and the video that support this claim. During his talk, Snelgrove comments that we know more about the Moon or Mars than we do about the deep-sea floor and marine habitat as a whole. Why is this surprising and even ironic? Snelgrove describes a fishing disaster that occurred where he grew up in Canada in an effort to explain how we are now experiencing “shifting baselines.” Explain what he means by this term. According to Snelgrove, if you were to suck all of the water out of the ocean, what would you be left with? Describe what Snelgrove discusses in terms of how the oceans play a part in global collaboration. Discuss the concerns Snelgrove has regarding the health and safety of our oceans and ocean life. As he concludes his talk, Snelgrove says, “And as the oceans go, so shall we.” Explain what he means by this statement.
Answer:
Snelgrove showed the value of the ocean and its wellbeing to humans. We rely on the sea, and as it fights and declines, we all start to work as well.

Explanation:
Meat tenderizer contains an enzyme that breaks down meat quickly at room temperature. If meat is coated with tenderizer and then placed in a refrigerator, how would the enzyme be affected?
Answer:
The enzyme would be deactivated
Explanation:
If a meat coated with tenderizer is placed in a refrigerator, the cold environment of the refrigerator would deactivate the enzyme.
Enzymes are generally sensitive to temperature with high temperature capable of destroying the polypeptide bonds that hold the amino acids together thus denaturing their proteinous nature. At low temperatures, the molecules of the enzyme move less and less until the enzyme becomes deactivated.

How can you explain how genetic similarities are due to common ancestry? Where do we get our DNA from?
Answer:
Actually our genetic code is unrepeatable, the union of the female x chromosomes of our mother and chromosomes and of our father, generate a diploid cell with a UNIQUE cellular genetic code.
What shows our descent from the same ancestor is mitochondrial DNA, this DNA is the same and is repeated throughout the human race.
Explanation:
Mitochondrial DNA is circular and is found in our organelle called mitochondria, responsible for cellular respiration and formation of the energy currency ATP-

The human genome is a diploid genome. However, when germ-line cells produce gametes, these specialized cells are haploid. What is the total number of chromosomes found in each of the gametes (egg or sperm) in your body
Answer:
23 chromosomes
Explanation:
The total number of chromosomes found in each of the gametes in the body of humans is 23.
The human genome is diploid (2n) with 46 chromosomes. The sex cells divide by meiosis - a reductional division that results in the halving of the chromosome number - during the formation of gametes. Hence, the gametes are haploid (n) with half the number of chromosomes (23) of the vegetative cells of the body.
Therefore, the eggs in females and the sperms in males each contain haploid (n=23) number of chromosomes.
