The color of a light wave is determined by its wavelength. On the COLOR tab, slowly drag the Light wavelength slider back and forth and observe the effect on oxygen production. How does the color of light affect the rate of photosynthesis
Answer:
The color of light determines how effective chlorophyll pigment will be at absorbing light.
Explanation:
Photosynthesis is a metabolic process that requires light, which is an electromagnetic radiation. Light on the electromagnetic spectrum is determined by wavelength. Each region/color of light occurs at a specific wavelength.
Hence, chlorophyll pigment, which is the major photosynthetic pigment effectively absorbs blue and red light in the visible light region of the electromagnetic spectrum. Hence, the rate of photosynthesis will be affected negatively if the color of light is not the one stated above.

You plan to clone a guide RNA sequence into the pML104 plasmid because you want to engineer the construct in bacteria and later express it in yeast. Unfortunately, your lab does not have any available pML104. Your friend in the lab next door lets you borrow a related plasmid pML107, and you quickly start your experiment. Will it work? Briefly explain.
Answer:
Yes, the experiment will work.
Explanation:
The reason behind this is that plasmids are well known to be DNA vector carriers. These plasmids have the ability to bring about changes in DNA fragments into various microorganisms and reveal them. The two plasmids compose of the same genomic marker such as the antibiotic resistance gene found in URA3. However, plasmids are most commonly found in bacteria, but also in eukaryotic cells. Oftentimes, the gene composition in the plasmids enhances the bacteria with a vantage edge such as antibiotic resistance.
Hence, it is obvious that in both, the molecular regulation in terms of expression of genes is alike in properties. Similarly, the numbers of copies and molecular weight are also the same.
We can thereby conclude that, provided that there is a proper restriction site, another host that is up to standard for plasmid can be replaced for each other.

1. Robin carries the trash from the house to the garbage can outside. Which statement best describes the science of what he did?
He would use less energy if he were to move the garbage faster
He used energy to carry the garbage.
He did not have to work because garbage is light.
He caused the garbage to have potential energy when it moved.
Answer:
He used energy to carry the garbage.
Explanation:
Energy is the ability to do work. When work is done, energy is expended during the process. Work is done if the force applied on an object moves that object through a distance.
In the case where Robin carries the trash from the house to the garbage can outside, work is done because, the force applied by Robin on the trash effectively helps to move the trash from inside the house to the garbage can outside the house. During the process of moving the trash, Robin expends or uses energy to do the work.
From the given options:
He would use less energy if he were to move the garbage faster is wrong because an increase in speed results in an increase in energy
He used energy to carry the garbage is correct because energy is the ability to do work
He did not have to work because garbage is light is wrong because as long as an object is moved a distance, work is done irrespective of the mass of the object.
He caused the garbage to have potential energy when it moved can only be true if he had raised the garbage from the floor to a height above the ground. However, he only moved it fro inside to outside the house.
Carbon-14 is a radioactive isotope of carbon that has a half-life of about 5,730
years. You have discovered a fossil and want to know how old the fossil is. You count
the parent and daughter atoms and calculate that you have about 6.25% of the
parent atom (carbon-14) left. How old is the fossil? (Provide units (years) for your
final answer. You must show your work.
2 points for showing work
1 point for final answer with units
Answer:
22,920 years
Explanation:
When the fossil first started to decay, it must have had 100% of its parent carbon-14 atoms. Every 5,730 years, that amount gets cut in half. Let's travel back a ways, to the very beginning, 0 years into the decay. We'll keep track of the time elapsed, the number of half-lifes, and the percent of carbon-14 remaining:
0 years (0 half-lives) - 100%5,730 years (1 half-life) - 50%11,460 years (2 half-lives) - 25%17,190 years (3 half-lives) - 11.5%22,920 years (4 half-lives) - 6.25%That last one represents our situation, so the fossil is 22,920 years old.

Two different species of mammals competing for the same water source is an example of two organisms competing for an abiotic factor.
What is abiotic factor?
Abiotic factors refers to non-living physical parts of the environment that affect living organisms as well as the functioning of ecosystems. In the above example, water source is a non-living part of an ecosystem which is required by both organisms.
This leads to competition of two mammals so we can conclude that two different species of mammals competing for the same water source is an example of two organisms competing for an abiotic factor.

2. Name a microbe that lacks a cell wall and would find hypotonic environments detrimental.
Answer:
I so I am also a bit confused, but I hope this could answer your question!
Explanation:
The bacteria possess a cell wall composed of peptidoglycan molecule formed by the amino acids called murine. The bacterial cell wall helps in the survival of the bacteria in some extreme condition like when placed in a hypotonic solution.
The hypotonic solution is formed when it has low solute concentration and high water amount when compared. When the bacterial cell will be placed in hypotonic solution then the water will move inside the cell down the concentration gradient as a result of which the bacterial cell will swell but will not burst.
This happens as the cell wall contains expansin protein which allows the cell wall to expand and provides rigidity to the cell.

Human growth hormone (HGH) is necessary for growth during human adolescence. Pituitary dwarfism is a condition that results from the inability of a person to produce HGH. Luckily, the human gene for HGH can be inserted into E. coli bacteria, which are able to make our HGH. The resulting HGH is used by people who are unable to make their own. What property about hereditary information makes this possible
Answer:
The correct answer is - DNA is a genetic language that is common and uses by every organism including humans and bacteria.
Explanation:
DNA is the unit of heredity and present in almost every living organism, it carries the genetic information and transfer from generation to generations. In this process of transfer of the genetic information, there are two processes transcription and translation helps to produce protein.
The ability to produce proteins with the help of DNA for the particular function as said in question which is HGH production. Correcting the abnormality of not able to produce HGH, to produce the normal protein with the help of putting human genes into Bacteria as DNA is universal genetic language.
3. A population of 70 jaguars lives in a rainforest measuring 350 square miles. What is the population
density of the jaguars? (Hint: You cannot have a fraction of a jaguar)
Answer:
5 jaguars per square mile.
Explanation:
If you do 350 ÷ 70 it comes to 5, so that means it's 5 jaguars per square mile. Have a fun day. :)
The population density of jaguars in the rainforest is 0.2 jaguars per square mile.
To calculate the population density, we divide the total number of individuals (70 jaguars) by the area of the habitat (350 square miles).
Population density = Total number of individuals / Area
Population density = 70 jaguars / 350 square miles
Simplifying the calculation, we find that 70 divided by 350 equals 0.2. Therefore, the population density of jaguars in the rainforest is 0.2 jaguars per square mile.
Population density is a measure of how concentrated a population is within a given area. In this case, it tells us how many jaguars are found on average in each square mile of the rainforest. A population density of 0.2 jaguars per square mile means that, on average, there are 0.2 jaguars in every square mile of the rainforest.
It's important to note that population density can vary across different habitats and species. Factors such as food availability, territory size, and reproductive behavior can influence the distribution and concentration of individuals within a given area. Understanding population density helps researchers assess the health of a population, monitor changes over time, and make informed conservation and management decisions.

Sickle cell anemia and albinism are both recessive traits in humans. Imagine that a couple, already pregnant with fraternal twins, has just learned that they (the couple) are both heterozygous for both of these traits. As the couple's genetic counselor, the couple asks you what is the probability of having both of the twins be albino and have sickle-cell anemia.
Answer:
81/256
Explanation:
By doing a test cross of albinism and sickle cell anemia you'll see that the probability that one child is unaffected by either conditions will be 9/16. Both children would be 9/16 * 9/16.
Since fraternal twins are developed from two separate fertilization events the probability chance will be independent.
What is phagocytosis in regard to the immune system of humans?
Answer:
Phagocytosis is the process of introducing larger particles into a larger cell. The process takes place by twisting the cell membrane of the "host" and enveloping the particles with a phagocytic bubble. Leukocytes use phagocytosis to take in and incapacitate bacteria that enter our body, so phagocytosis plays an important role in the immune system, as it prevents harmful cells from affecting humans.
