Pillbugs are placed in a container where they have a choice of a wet or a dry environment. Researchers record how much time was spent on each side. What is the INDEPENDENT variable?
Answer: Wet or dry environment.
Explanation:
The independent variable is the variable that a researcher manipulates in an experiment in order to carry out a study on the incidence of the expression of the dependent variable. Therefore, the independent variable is the one that changes or is controlled to see its effects on the dependent variable.
Researchers can then design a container with a wet or dry environment. But it's the pillbugs that are going to choose where to go and how long to spend in each part. So the time they spend in each part is a dependent variable since that cannot be controlled by the scientists conducting the experiment. Henceforth, the researches will just record this dependent variable without controlling it. But they can decide what to put in the container to make it wet or dry environment, or whatever they want to design. So wet or dry environment is the independent variable.
Answer:the independent variable is whether the pillbugs choose a wet or dry environment. The dependent variable how much time was spent on each side.

Explanation:
Nitrogenous bases are used to construct nucleotides. Until the discovery of the helical shape of the DNA molecule, were only possible to identify the genetic material (chromosomes) by the microscope. Chromosomes are composed of DNA and proteins (histones). Nucleotides are the building blocks of the DNA molecule. The X-ray diffraction data obtained by Rosalind Franklin were used to decipher the DNA structure. The ball-and-stick is a molecular model where atoms are represented by spheres and bonds are represented by rods. Chargaff's rules indicate that the content of cytosine is equal to guanine and adenine is equal to thymine. Rosalind Franklin died of ovarian cancer in 1958. The double-stranded DNA molecule must be unwound and then the DNA strands serve as templates to synthesize identical DNA molecules.
How are the molecules in photosynthesis and cellular respiration similar? Please include descriptions of the molecules
Answer:
They are similar because they both produce energy but in two different forms.
Photosynthesis- It produces oxygen and G3P, simple carbohydrate molecules that are high in energy and can be converted into glucose, sucrose, or other sugar molecules.
cellular respiration-During cellular respiration, a glucose molecule is gradually broken down into carbon dioxide and water.
They exhibit the same responses, but they do so in reverse. Carbon dioxide and water are converted during photosynthesis into glucose and oxygen. Carbon dioxide and water are produced during respiration in exchange for glucose and oxygen.
What similarity in photosynthesis and cellular respiration?Energy transformations from one form to another are a part of both respiration and photosynthesis through a sequence of metabolic reactions.
The reactions that are carried out by both processes—which both use and produce ATP—are carried out on membranes and are managed by enzymes.
Light energy is converted by photosynthesis into chemical energy that is stored in glucose, which is then released by cellular respiration to create ATP, the life-sustaining compound.
Therefore, They are similar because they both produce energy, but in two different forms.

In natural selection when more offspring is survived is a sign of higher fitness of the particular population, hence given statement is true.
What is natural selection?Most qualities are inherited, there are more children generated than can survive, and offspring with more advantageous features will survive and have more offspring than those with less advantageous traits leading to the inevitable process of natural selection.
Since there are only so many resources available, more creatures are born than can live those who are better at obtaining food.
Mating or evading predators will have a higher chance of thriving, procreating, and passing on their DNA.
Therefore an individual in the population has offspring to survive more in number.

In glycolysis, pyruvate, ATP, and NADH are produced. The lactic acid fermentation process uses the NADH molecule from glycolysis to convert pyruvate into lactate. During lactic acid fermentation, the NADH molecule transfers electrons to the pyruvate molecule and is converted to NAD+. How do you think this transfer of electrons helps the lactic acid fermentation process repeat itself? will give brainliest
Answer:
Explanation:
Fermentation does not involve an electron transport system, and no ATP is made by the fermentation process directly. Fermenters make very little ATP—only two ATP molecules per glucose molecule during glycolysis. ... During lactic acid fermentation, pyruvate accepts electrons from NADH and is reduced to lactic acid.
The NADH needed to convert pyruvate to lactate is supplied by this reaction of glycolysis, so the transfer of electrons helps to repeat the lactic acid fermentation process as lactate is reduced to pyruvate to regenerate NAD+ which is are reused for uninterrupted operation.
What is Glycolysis?Glycolysis is defined as the metabolic pathway that converts glucose to pyruvate where the free energy released in this process is used to form the high-energy molecule adenosine triphosphate and the lesser nicotinamide adenine dinucleotide. It is a sequence of ten reactions catalyzed by enzymes.
During glycolysis , ATP and NADH are produced where lactic acid fermentation process uses NADH molecule from glycolysis molecule to convert pyruvate to lactate. During lactic acid fermentation, NADH transfers its electron to pyruvate and is oxidized to NAD+ while pyruvate is reduced to lactate.
NAD+ assisted dehydrogenation and phosphorylation of glyceraldehyde-3-phosphate (G3P) to 1,3-biphosphoglycerate (1,3-BPG) is coupled to lactate production where NADH is supplied to convert pyruvate to lactate, hence, the transfer of electrons helps the lactic acid fermentation process to repeat itself as the reduction of pyruvate to lactate regenerates NAD+ which is reused for uninterrupted operation
Thus, the NADH needed to convert pyruvate to lactate is supplied by this reaction of glycolysis, so the transfer of electrons helps to repeat the lactic acid fermentation process as lactate is reduced to pyruvate to regenerate NAD+ which is are reused for uninterrupted operation.

What happens when volcanoes release greenhouse gases into the atmosphere?
Answer:
a. the climate gets warmer...
Explanation:
When volcanoes release greenhouse gases into the atmosphere, global warming is due to the greenhouse effect.
What do you mean by the Greenhouse effect?The Greenhouse effect may be defined as the phenomenon of keeping the earth warm due to the presence of certain gases in the atmosphere.
Greenhouse gases like carbon dioxide, Methane, and Nitrous oxide allow the solar radiations to enter but prevent the escape of heat radiations of longer wavelength.
Due to this, the gradual and continuous increase in the average temperature of the earth's surface occurs, a phenomenon known as global warming.
Therefore, when volcanoes release greenhouse gases into the atmosphere, global warming is due to the greenhouse effect.
