Answer: I put DNA and i'm sure thats the answer
Explanation: DNA is found in the nucleus of every cell in your body. It contains genetic information, in the form of genes, which are passed on from one generation to the next. Your DNA determines all of your traits.
The list which correctly summarizes the main functions of proteins in the human body is the last one - p<span>owering movement, structural support, hormone production, antibody and enzyme production.
Skeletal muscles are responsible for movement and those muscles are made of protein. </span>
Answer:
In a fruit fly experiment, grey body, normal winged (homozygous dominant) fruit flies were mated with black body, short winged (homozygous recessive) fruit flies. The F1 dihybrid females were then used in a test cross. If the genes are always linked and no crossing over occurs, what would be the predicted ratio in the F2 generation?
GG x bb = Gb, Gb, Gb and Gb F1 generation
grey body heterozygous offspring 4:0
Gb x Gb= GG, Gb, Gb, and bb F2 generation
3:1 three grey body fly and one black body fly

Answer:
2nd one
Explanation:
Regardless of latitude or time of year, the sun's angle reaches closest to 90 degrees (perpendicular lines are 90 degrees) -- and is therefore at its most intense -- at the midpoint of the day: noon.
Answer:
Phospholipid bilayer.
Explanation:
The plasma membrane (also known as the cell membrane or cytoplasmic membrane) is defined as a biological membrane that separates the interiors of a cell from its external environment.
The plasma membrane has a function that protects the cell from its external environment, mediates cellular transport, and transmits cellular signals.
It is composed of a lipids bilayer (phospholipids and cholesterol), (phospholipid is a lipid made of glycerol, two fatty acid tails, and a phosphate-linked head group) with embedded proteins, the plasma membrane is selectively permeable to ions and organic molecules which hence, regulates the movement of substances in and out of cells. Plasma membranes is very flexible in order to allow cells change form example, red blood cells change shape as they pass through narrow capillaries.
