Answer:
it is an independent variable as it can be changed by studying and also a dependent variable as you can measure her results and see its increase or decrease
Explanation:
hope this helps
could u pls help me with my latest questions pls pls pls pls pls
The variables in the given situation would be as follows:
A). Independent Variable: Amount of time given on study
B). Dependent Variable: Grade in Science
C). Control: Additional Study of 30 minutes
In an experiment or research, an independent variable is described as a variable that remains unaffected by the change in other but rather a manipulation or change in it can affect the other variables. Dependent variables are the variables that receive a direct effect of change in the other variable and therefore, it is the variable that the researcher aims to measure or study.While control helps in making the comparison of the results with or without it. Thus, the given variables are classified in this situation as mentioned above.

Which statement is the first step of protein synthesis?(1 point) A ribosome attaches to the mRNA. DNA unzips between the base pairs. tRNA carries amino acids to the ribosome and attaches it to the mRNA strand. Amino acids are linked together with peptide bonds.
Answer:
DNA unzips between base pairs.
Explanation:
This is the first step of protein synthesis.
The first step of protein synthesis is attachment of mRNA to ribosomes. Option A is correct.
Protein synthesis:
It is known as translation. In this mRNA is translated in to the sequence of amino acids which ultimately form protein.
First mRNA attach to ribosome,tRNA bring amino acid to ribosomes and attach to mRNA.Amino acids bond together via peptide bond.Therefore, the first step of protein synthesis is attachment of mRNA to ribosomes.

Answer:
A single phospholipid molecule has a phosphate group on one end, called the “head,” and two side-by-side chains of fatty acids that make up the lipid “tails. ” The phosphate group is negatively charged, making the head polar and hydrophilic, or “water loving.” The phosphate heads are thus attracted to the water

A person’s will be the same on Jupiter and Earth. A person’s will be greater on Jupiter than on Earth.
Answer:
Greater on Jupiter
Explanation:
Gravity depends on mass. Jupiter has more mass than Earth so its gravity is two and a half times greater. Therefore a person will weigh more on Jupiter.
Answer:
A person will be greater on Jupiter than Earth. The surface gravity is having is larger than Earth’s by roughly 2.4 times. So, if you weigh 100 pounds on Earth it would be 240 on Jupiter. Hopefully this helps! Feel free to mark this as brainliest!
A cell membrane is very specific about what it allows across. How does t help the cell?
Answer:
Explanation:
The cell membrane (also known as the plasma membrane (PM) or cytoplasmic membrane, and historically referred to as the plasmalemma) is a biological membrane that separates the interior of all cells from the outside environment (the extracellular space) which protects the cell from its environment.[1][2] The cell membrane consists of a lipid bilayer, including cholesterols (a lipid component) that sit between phospholipids to maintain their fluidity at various temperatures. The membrane also contains membrane proteins, including integral proteins that go across the membrane serving as membrane transporters, and peripheral proteins that loosely attach to the outer (peripheral) side of the cell membrane, acting as enzymes shaping the cell.[3] The cell membrane controls the movement of substances in and out of cells and organelles. In this way, it is selectively permeable to ions and organic molecules.[4] In addition, cell membranes are involved in a variety of cellular processes such as cell adhesion, ion conductivity and cell signalling and serve as the attachment surface for several extracellular structures, including the cell wall, the carbohydrate layer called the glycocalyx, and the intracellular network of protein fibers called the cytoskeleton. In the field of synthetic biology, cell membranes can be artificially reassembled

why is carbon the most versatile element in living organisms?
Answer:
Because it has four electrons in its second orbital, which can accommodate eight, carbon can combine in many different ways, and it can form very large molecules. Carbon bonds are strong and can stay together in water. Carbon is such a versatile element that almost 10 million different carbon compounds exist.

Which of the following are the best sources of longer-term, stored energy for our bodies?
A. Monosaccharides
B. Disaccharides
C. Polysaccharides
The best source of longer-term energy storage for our bodies are Polysaccharides. Option C is correct.
Saccharides are sugar molecules. Among these molecules, some are shorter than others though all of them provide very similar functions to our bodies. Our bodies break down these sugars in order to obtain energy.
Due to the nature of everyday life, our bodies at times need a quick source of energy, as well as energy to be stored for later. This is where the difference in saccharides comes into play. Monosaccharides and Disaccharides are a source of quick energy, due to their being short molecules they can be broken with ease for quick use.
On the other hand, Polysaccharides are chains of sugar that can at times span into the thousands. These chains are later quickly broken up into monosaccharides at times of need. This characteristic makes them ideal for long-term storage of energy and is the reason that option C is correct.
