Answer: genome. The human genome
Explanation:
contains somewhere between 20,000 and 25,000 genes.
Answer:
The correct option is <u>B. Lipids</u>
Explanation:
Lipids can be described as molecules which dissolve in non-polar solvents and cannot dissolve in water. The biological function of a lipid molecule is to store energy as well as to structure the shape of cell membranes. Lipids are also used in a cell for signalling.
Lipids are made up of carbon, hydrogen and oxygen. Some lipids might have phosphorus in them like the phospholipids which make up the cell membrane.
Answer: mitotic phase
Explanation:
The cell cycle has two phases the Interphase and mitosis. Interphase is the growth phase where the cell prepares itself for the cell division. It is divided into three phase G1 phase( Cell growth),S phase ( DNA synthesis) and G2 phase(cell growth).
Mitotic phase has a multiple steps this is where the duplicated chromosomes are aligned or arranged, separated, and move into two new, identical daughter cells(cytokinesis)
The first step in the mitotic phase is called karyokinesis or nuclear division where the chromosomes are separated and move in opposite direction and the second portion of the mitotic phase, called cytokinesis which is the physical separation of the chromatids into the two daughter cells.
<span>D. Temperature and pH can affect how enzymes work.</span> The action of enzymes can be affected by many factors including temperature, pH and ionic strength. Optimum pH differs per enzyme. Enzymes can be destroyed by heat more than the allowed optimum temperature.
Answer:
Un elemento químico es un tipo de materia constituida por átomos de la misma clase. En su forma más simple, posee un número determinado de protones en su núcleo haciéndolo pertenecer a una categoría única clasificada por su número atómico, aun cuando este pueda desplegar distintas masas atómicas.
