How the structure of DNA determines the structure of proteins?
Answer:
DNA carries the genetic information for making proteins. ... The base sequence determines amino acid sequence in protein. Messenger RNA (mRNA) is a molecule which carries a copy of the code from the DNA, in the nucleus, to a ribosome, where the protein is assembled from amino acids.

5) The following picture is of a single organism that has been Gram stained and is viewed under oil immersion on the compound light microscope. What is the reason for a single organism appearing like this after being Gram stained
Hi. You have not submitted any images about the microorganism the question refers to. This makes it impossible for me to answer your question. However, I will try to help you as best I can.
Gram stain is a test done to find out whether the bacteria are gram negative or gram positive. In this test, the bacteria are submitted to a certain type of dye and then are observed under a microscope. If the bacteria is gram positive, it will be purple in color. If the bacteria is gram negative, it will be red in color.
This is because after they are subjected to the violet dye, both types of bacteria absorb the color of the dye. However, before being observed under the microscope, the bacteria are washed with alcohol. Alcohol removes the dye from the gram negative bacteria, leaving them reddish. On the other hand, in gram positive bacteria, alcohol dehydrates the cell wall, compressing the pores and making the cell wall impermeable, preventing the dye from being released and, therefore, leaving the bacteria with a purple color.

Duckweed is a tiny floating aquatic plant that can reproduce so rapidly that it can completely cover the surface of small fish hatchery ponds. One proposal to limit the growth of this invasive plant is to use colored panels to shield the ponds, inhibit photosynthesis, and kill this pest. What color filters would you order for the panels in this project
Answer:
Green color filter
Explanation:
It is given that Duckweed grown on water and covers all part of the pond very rapidly. In order to limit their growth is proposed to use a color panel so as to shield the ponds and inhibit photosynthesis process and also kill the pests.
So a green colored panels can be used to shield the pond. This is because the photosynthetic pigments such as the chlorophylls absorbs all the green frequencies of the visible light except for the wavelength that corresponds to the green color. Therefore, by using a green filter, the wavelength corresponding to blue, yellow, red and purple colors are absorbed. Thus the plants would not be able to use the green light for the process of photosynthesis. This would help in limiting the growth of the duckweeds.

Compare Law of Conservation of energy and Law of Conservation of matter?
Answer:
Conservation of energy, principle of physics according to which the energy of interacting bodies or particles in a closed system remains constant. The first kind of energy to be recognized was kinetic energy, or energy of motion. In certain particle collisions, called elastic, the sum of the kinetic energy of the particles before collision is equal to the sum of the kinetic energy.
Explanation:
Super saturated solutions are used to make rock candy. Please describe how the crystals are formed, be sure to use the terms Solute and Solvent.
Answer:
Once the solution cools, it now has more solute than it normally could have, and this is called a supersaturated solution. Once a solution becomes supersaturated, it wants to crystallize the excess solute. The solute will form crystals on any surface. In our case the surface is a string, and we are using a lifesaver candy as our “seed.”
Explanation:
Rock candy is a type of candy made by growing sugar crystals on a string or stick.
Why are Super saturated solutions used?Super saturated solutions are often used to make rock candy because they contain more solute (sugar) than the solvent (water) can normally dissolve at a given temperature.
The first step in making rock candy is to heat water in a saucepan and add sugar to it. The sugar dissolves and forms a solution as the water heats up. After that, the solution is heated until it is completely saturated.
This occurs because the super saturated solution is unstable, and the excess solute (sugar) in the solution wants to escape and form crystals.
As time passes, more sugar dissolves from the solution and adheres to the crystals on the string or stick, causing them to grow larger.
The process is repeated until the crystals reach the desired size or until all of the excess solute has been removed from the solution.
Thus, preparing a super saturated solution of sugar and water, then dipping a string or stick into the solution and allowing the excess solute to come out of the solution and form crystals on the string or stick, is the process of making rock candy.

After a skeletal muscle fiber is treated with a membrane permeable drug that speeds up the action of the SR Ca 2-ATPase, how would contraction differ after multiple and frequent action potentials
Answer:
the twitch would be shorter
Explanation:
In muscle cells, the calcium (Ca2+) pump ATPase membrane transport proteins maintain a low cytosolic Ca2+ concentration in order to promote muscle contraction. Muscle relaxation occurs when the sarcoplasmic reticulum reabsorbs Ca2+ through the Ca2+-ATPase protein, thereby reducing intramuscular Ca2+ levels. In muscle contraction, intracellular Ca2+ levels are raised due to the release of Ca2+ from the sarcoplasmic reticulum (SR) via Ca2+-release channels. In consequence, it is expected that a specific drug that speeds up the action of (Ca2+) pump ATPase protein should shorten the contraction-relaxation cycle by increasing the velocity of muscle relaxation.

Explanation:
During exercise, epinephrine and norepinephrine are released from the adrenal medulla. Epinephrine and norepinephrine have the same effect on plasma glucose levels as glucagon. Explain how epinephrine and norepinephrine affect plasma glucose and why this is important during exercise.
Answer and explanation:
Epinephrine and norepinephrine are two hormones that are released from the adrenal medulla when the body is under stress (like during exercise, for example) as a part of the sympathetic response.
These hormones have many functions and they all work together to prepare the individual for a fight or flight response - like increasing heart rate and producing bronchodilatation. One of these functions is the rise of glucose levels in blood which is important for this substance to reach several tissues, like the skeletal muscle. The skeletal muscle will make use of this glucose to produce ATP and generate the required energy for muscle contraction through a process called glycolysis, which is key for the fight or flight response mentioned above.
When we exercise, glucose levels rise thanks to these hormones so the skeletal muscle can have enough energy to contract and move as we want. If the exercise is too intense or prolongued, glucose levels will drop and other fuels will be needed to sustain this activity, like stored glycogen and fat.

1. Why is diversity important in maintaining the stability of an ecosystem?
2. What is the broadest level of ecological classification within the biosphere?
What are the major abiotic factors used to characterize them?
3. What is the importance of plants in the ecosystem?
Answer:
if the ecosystem has a diverse range of species, it is more likely to stay safe against any virus that arises. That’s why biodiversity is important to ecosystems because it protects the environment from extreme conditions. Even if some species fail to survive, others will remain to sustain the ecosystem and the living things.
