The spiral configuration of the deoxyribonucleic acid (DNA) molecule is called: a double helix.
Deoxyribonucleotides is the fundamental (basic) unit of a deoxyribonucleic acid (DNA).
Also, deoxyribonucleotides comprises a phosphate group and nitrogenous base that are called deoxyribose sugar.
A double helix refers to the spiral configuration of the deoxyribonucleic acid (DNA) molecule.
Basically, a double helix is typically used to describe the molecular shape of a double-stranded deoxyribonucleic acid (DNA) molecule, which comprises two (2) linear strands that are anti-parallel or run opposite to each other and twist together.

And the last one would be a lot more crimes and political issues? I'm not sure if the last one is valid but the first 2 are definitely counted.
Explanation:
If you experimentally increase the concentration of Na outside a cell while maintaining other ion concentrations as they were, what would happen to the cell's membrane potential
Given what we know about membrane polarization, we can confirm that If you experimentally increase the concentration of Na outside a cell while maintaining other ion concentrations as they were, the cells membrane potential would increase and be positively charged.
Increasing the concentration of Na outside a cell would cause there to be an increase and a build-up of positive charges outside of the cell. Due to the fact that the ion concentrations inside the cell remain constant, we can confirm that there will be a net positive charge on the outside of the cell and this will cause an increase in the membrane's potential.

What is an example technology that uses NLS?/ why is it important
Please someone answer!
Explanation:
NLS, or the "oN-Line System", was a revolutionary computer collaboration system developed in the 1960s. Designed by Douglas Engelbart and implemented by researchers at the Augmentation Research Center (ARC) at the Stanford Research Institute (SRI), the NLS system was the first to employ the practical use of hypertext links, the mouse, raster-scan video monitors, information organized by relevance, screen windowing, presentation programs, and other modern computing concepts. It was funded by ARPA (the predecessor to Defense Advanced Research Projects Agency), NASA, and the US Air Force
the primary auditory cortex is located in the ________.
Answer:
temporal lobe
Explanation:
The temporal lobe of brain is located in the main auditory cortex.
Thus, in the superior temporal gyrus, which is located on the lateral surface of the brain, it is specially located. A specialized area called the primary auditory cortex is in charge of processing auditory data brought in by the ears.
The auditory pathways provide information, and it analyses different auditory properties including frequency, intensity, and spatial placement. The perception, identification, and interpretation of sound all depend on this area of the brain. The primary auditory cortex helps us detect and comprehend the auditory environment around us by mapping sound signals.

How do organisms get the energy they need? Choose the correct answer. Plants get energy from fertilizers. Animals get energy from water. Plants get energy from the soil. Animals get energy directly from sunlight. Plants do not need energy because they do not move. Animals get energy from food. Plants use energy from sunlight to make sugar molecules. Animals get energy from eating other organisms.
Answer:
If you are allowed multiple answers, I would choose: Plants use energy from sunlight to make sugar molecules. and Animals get energy from food.
Explanation:
Plants undergo photosynthesis, which uses sunlight to produce glucose, used for energy. Animals use food for energy, after digestion where the proteins and other valuable molecules from the food are used for reactions in the body.
Why are the average temperatures in the middle of the United States warmer than the coasts? I NEED THIS ANSWER ASAP!
Answer:
Here
Explanation:
The environment of the United States shifts because of changes in scope, and a scope of geographic highlights, including mountains and deserts. By and large, on the central area, the environment of the U.S. becomes warmer the further south one ventures, and drier the further west, until one arrives at the West Coast.
Being near huge amounts of water, such as oceans, lowers the temperature of a site that is just as close to the equator as one without any. As a result, temperatures in the middle of the country rise far more than in coastal states.

Four substances are involved in both photosynthesis and cellular respiration. They are sugars, water, oxygen, and carbon dioxide. Energy is also transformed from one type to another. Describe what happens to these four substances, light energy, and chemical energy during photosynthesis. Then write a simple equation for the substances and another for energy, using words and arrows to illustrate these changes.
Answer:
Explanation:
The process of photosynthesis is complex. Sunlight energy is converted into chemical energy by using chlorophyll, which is what gives plants their green color. Chlorophyll absorbs red and blue light and uses the energy to convert water and carbon dioxide into glucose then releases the unused components such as oxygen.
Answer:
The four substances recycled during photosynthesis and respiration are carbon dioxide, water, oxygen and glucose.Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
Which structure determines what molecules can enter and leave the cell?
(a) the plasma membrane
(b) the cell wall
(c) the nucleus
(d) all of the above
Answer:
(a) the plasma membrane
Explanation:
also called as the cell membrane
The structure that determines what molecules can enter and leave the cell is the plasma membrane. The correct answer is option a.
The plasma membrane is a selectively permeable membrane that regulates the movement of substances in and out of the cell.
It is composed of a phospholipid bilayer with embedded proteins and other molecules that help to control the flow of molecules across the membrane. It is responsible for maintaining the internal environment of the cell and for allowing the cell to interact with its external environment.
Therefore, the plasma membrane is the structure that determines what molecules can enter and leave the cell. Option a is the correct answer.

what is a atom?
what are the three subatomic particles and their particles?
what two subatomic particles are found in the nucleus?
what charge does the nucleus have?
where are electrons found?
An atom is the smallest unit of ordinary matter that forms a chemical element. Every solid, liquid, gas, and plasma is composed of neutral or ionized atoms. Atoms are extremely small, typically around 100 picometers across.
There are three subatomic particles: protons, neutrons and electrons. Two of the subatomic particles have electrical charges: protons have a positive charge while electrons have a negative charge. Neutrons, on the other hand, don't have a charge.
The nucleus (or center) of an atom is made up of protons and neutrons.
positive charge
The nucleus has an overall positive charge as it contains the protons. Every atom has no overall charge (neutral). This is because they contain equal numbers of positive protons and negative electrons. These opposite charges cancel each other out making the atom neutral.
outside
Unlike protons and neutrons, which are located inside the nucleus at the center of the atom, electrons are found outside the nucleus. Because opposite electric charges attract each other, negative electrons are attracted to the positive nucleus.
