Answer:
This question lacks options, but the answer is TEMPERATURE
Explanation:
In an experiment, two common variables are used: independent and dependent variable. The independent variable is the variable that is changed or manipulated by the experimenter in order to effect a response in the dependent variable.
The dependent variable, on the other hand, is the responding variable or the variable that is measured by the experimenter. Note that, It is dependent on the independent variable.
In this question, the independent variable is DIFFERENT TEMPERATURE that the enzymes were exposed to because it is what is being changed by the researcher. The dependent variable is the EFFECTIVENESS OF THE ENZYME, which is dependent on the temperature it is exposed to.
Hence, how well an enzyme works (effectiveness) is determined by the TEMPERATURE

an mRNA molecule. Use the word bank and sentence frames below, or write
your own sentences.
Answers
The summary on transcription on how a gene directs the synthesis of an mRNA molecule using sentence frames can be found below.
How to write a summary?Initially, a gene located in the nucleus of a cell serves as a template for the synthesis of messenger RNA (mRNA) molecules. The gene is made up of DNA, which consists of nucleotides that are arranged in a specific sequence according to the base-pairing rule.
Next, an enzyme called RNA polymerase binds to a specific region of the gene, known as the promoter, and begins to move along the DNA strand, separating the two strands and using one of them as a template.
Meanwhile, the RNA polymerase adds nucleotides to the growing mRNA molecule in a complementary sequence to the template strand of DNA. As the RNA polymerase moves along the DNA, the mRNA strand is formed by linking nucleotides together through chemical bonds.
Finally, once the RNA polymerase reaches the end of the gene, it releases the newly synthesized mRNA molecule, which then travels out of the nucleus and into the cytoplasm, where it directs the synthesis of a protein.

In eastern gray squirrels, Sciurus carolinensis, the allele for black fur (B) is dominant to the allele for gray fur (b). In a particular population of gray squirrels, 64% have black fur and 36% have gray fur. A researcher calculated the allelic frequencies to be B=0.4 and b=0.6. Five years later, the researcher returned to the location and determined the allelic frequencies within the squirrel population to be B=0.6B and b=0.4b.
Which of the following could best explain the increase in the frequency of the B allele in the population after five years?
The frequency of the B allele increased due to the selective pressures of the environment.
Answers
It is possible that the frequency of the B allele increased due to the selective pressures of the environment, but this cannot be determined definitively based on the given information alone.
In order to better understand the increase in the frequency of the B allele, additional information is needed. For example, if the population had experienced a change in environmental conditions that favored black-furred squirrels, such as a decrease in the amount of snow cover or an increase in the prevalence of predators that are less able to detect black fur, this could have led to an increase in the frequency of the B allele over time.
Alternatively, the increase in frequency of the B allele could be due to genetic drift, which is the random fluctuation of allele frequencies in a population over time. It is possible that chance events, such as the deaths of a larger number of gray-furred individuals, could have resulted in an increase in the frequency of the B allele.
In conclusion, while it is possible that the increase in the frequency of the B allele was due to selective pressures of the environment, additional information is needed to definitively determine the cause.

A cell has two sets of DNA (One from the mother and one from the father) is called _____.But a cell that has only one side of DNA is called _____.(and why are the answers not Chromo, and somatic)
Answers
Recall from the previous multiple-choice problems diploid cells and haploid cells:
• Diploid cells, ,are cells that have 2 sets of chromosomes (1 from each parent). Somatic cells are an example of ,2n, cells.
,• Haploid cells, ,are cells that have only ,1, set of chromosomes (from homologous pairs). Gametes are an example of ,n, cells.
Let's use this information to help us fill in the blanks:
• A cell has two sets of DNA (One from the mother and one from the father) is called ,a somatic cell/diploid cell,.
,• But a cell that has only one side of DNA is called ,a gamete/haploid cell,.
The answer for the 1st blank would not be chromo since that is not a cell type and doesn't describe the amount of chromosomes within a cell. The answer for the 2nd blank would not be somatic because somatic cells have 2 sets of chromosomes, not 1, so it would actually be a gamete cell.

Answers
The table Paramecium Contractile Vacuole Contractions which correctly describes the bars on a bar graph representing the data is the bars range from tallest for very high concentration to shortest for very low concentration.
The data in the table records the number of contractions per minute of a paramecium's contractile vacuole in response to different salt concentrations in the surrounding environment.
A bar graph representing this data would have five bars, one for each level of salt concentration.
The bars would vary in height according to the number of contractions per minute, with the tallest bar representing the highest salt concentration and the shortest bar representing the lowest salt concentration.
Therefore, the correct statement describing the bars on the bar graph would be: "The bars range from tallest for very high concentration to shortest for very low concentration."

How and why does the surface of the earth change
of the earth has changed?
Answers
Answer:
How and why does the surface of the earth change
of the earth has changed?
It can be hard to describe change on the surface without bringing up the interior. Earth is a system of constantly changing interactions between interior, surface conditions, and external events.
Volcanoes bring up new material and even create land. The Hawaiian islands, for instance are a chain of volcanoes on the surface, but the underlying structure is a single magma plume. In a way, the entire chain of islands is a single volcano that breaks through different places as the crust moves over it.
On that note: plates. Earth is made of tectonic plates that constantly move. Some grind against one another, others collide, and some pull apart. Depending on direction and interaction, you get anything from mountains, to spreading valleys, oceans, and anything else you care to name. Mountains can almost be viewed as something akin to the ridges of build up ice on a window scraper.
Erosion by water, wind, sand, chemicals, and living things changes the surface too. Materials on the surface face an incredible number of forces breaking them down and dragging them away, even as those same forces in different places and situations deposit those materials in other places, building things back up.
“Stardust” is also a thing. Rocks, dust, debris, and all sorts of random, natural cra.,p is constantly hitting our atmosphere. Regardless of whether or not it stays mostly intact, some material breaks off, and most of it does tend to make it to the surface, adding tiny amounts of matter all the time. …of course something BIG enough hitting the surface can throw rocks and chunks of surface clear into space, so that’s a thing too.
Remember when I mentioned living things? Living things D.,IE! Gac.k! And when they do, they break down into organic gunk. Soil - the stuff we grow crops in - is basically minerals and dead things that are decaying into nutritious, yummy, dir.,t.
Weather changes things too. Rain erodes, but rain that soaks a rock, and then is frozen by low temperatures, breaks the rock. Too much rain can create flooding, which results in a lot of sediment moving downstream. Heat can dry things out, crack the ground, and even slowly cook one kind of soil into another. Lightning can make glass out of sand, snow can collapse weak ground, not enough rain can dry out ground that could si.nk down without the extra pressure, and too much rain can literally move mountainsides if enough water adds its weight to the rocks and dir.t.
It’s always changing, and there is always more complexity to go into when studying it. There’s seldom a single cause, or reason, or effect for anything.
Explanation:
Have a great day!
The surface of the earth is constantly changing.
Explanation:
Wind, water,and ice break down large rocks and move sediments on the surface. Some events, though, change earth's surface much more quickly. These include volcanic eruptions, earthquakes, and landslides.

Answers
Answer:
hyperosmotic
Explanation:
Osmosis across a membrane occurs in nature as a result of concentration gradient i.e. difference in the solute concentration. Based on the concentration of solute in a solution which determines the osmotic pressure, a solution can either be hyperosmotic, hypoosmotic or isosmotic.
A hyperosmotic solution is that solution which contains more solute concentration in relation to another solution. In essence, a hyperosmotic solution will have more osmotic pressure than that of the body fluid. This will cause water to flow out of the body into the solution.

Answers
Atomic fission is the process through which energy is produced. The right answer is C.
Atomic splitting produces a particular form of energy known as fission. It is a nuclear process in which a huge quantity of energy is released along with the splitting of an atom's nucleus into two or more smaller nuclei.
In fission, neutrons are used to hit heavy atomic nuclei, such as uranium-235 or plutonium-239, creating an unstable nucleus.
Then, this nucleus splits into two or more smaller nuclei, releasing more neutrons and a substantial amount of energy in the process.

(3)
Answers
A sunken stoma is an adaptation found in the leaves of some plants that live in very dry conditions. The diagram below shows the structure of a sunken stoma and how it works:
As the diagram shows, the stoma is located in a sunken pit in the leaf. The walls of this pit are made up of two specialized epidermal cells called guard cells. These cells can swell or shrink to control the opening and closing of the stoma. When the stoma is open, gases can enter and exit the leaf.
When it is closed, the leaf is sealed off from the outside environment and gases cannot pass through. This helps to reduce water loss from the leaf and prevent desiccation. To further reduce transpiration, the sunken stoma also has an air chamber surrounding it.
This chamber is created by specialized mesophyll cells that surround the stoma. These cells have a compact arrangement that creates a space for air to collect. The air in this chamber is humid and saturated with water vapor, which helps to slow down the rate of water loss from the leaf. In summary, the sunken stoma reduces transpiration by having a specialized structure that allows it to close tightly and be surrounded by a humid air chamber.
