Answer:
The hair is made up of 95% keratin, a fibrous, helicoidal protein (shaped like a helix) that forms part of the skin and all its appendages (body hair, nails, etc.). Keratin is synthesized by keratinocytes and is insoluble in water, thus ensuring impermeability and protection for the hair.

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
means
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

Explanation:
All fish nitrogen into the water as ammonia and organic nitrogen. These chemicals are byproducts of their metabolism and respiration.
Answer:
The correct answer would be - release/excretes.
Explanation:
In ponds, rivers, or similar ecosystem nitrogen cycle is completed with the help of the fishes. In this ecosystem, the nitrogen cycle initiates with the eating plants or fish food by the fishes and performs metabolism and cellular respiration which produces byproduct ammonia and organic nitrogen as animal waste.
This waste is released or excreted by the fish in the water where the beneficial bacterium helps in restoring nitrogen back to the atmosphere by breaking these wastes.

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.

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
