Answer:
b, 8-10
Explanation:
your body needs 20 amino acids to grow, repair and function, however, only nine amino acids are 'essential' as such.
they are histidine, valine, isoleucine, methionine, phenylalanine, threonine, tryptophan, leucine, and lysine
hope this helps! :)
Cellular respiration is the chemical process that makes energy required for day-to-day metabolic functions of an organism. The resulting energy is in the form of a molecule called ATP (adenosine triphosphate). There are two types of cellular respiration: aerobic and anaerobic, but both types start with glycolysis. Glycolysis is the breakdown of glucose molecules which makes some ATP.
Aerobic respiration uses oxygen. It occurs in the mitochondria of cells. The overall chemical formula for this is
C6H12O6 + 6CO2 ---> 6CO2 + 6H20 + 38ATP
In this process, there are multiple stages: glycolysis, Krebs Cycle, and Electron Transport Chain (ETC). All of these stages are used to make ATP, but ETC makes the greatest amount of ATP. The other stages create reactants needed for ETC.
Anaerboic respiration does not use oxygen and is also called fermentation. It occurs after glycolysis. There are two types of this: lactic acid fermenation,which occurs in muscle cells and produces lactic acid, and alcoholic fermentation, which occurs in yeasts and can make bread and alcohol. The process produces some molecules that can produce more ATP in glycolysis.

Glycolysis in Respiration
Cells use oxygen to assist in cellular respiration. This type of respiration, called aerobic cellular respiration, converts stored energy into a usable form, chiefly by reacting glucose and oxygen through an intermediate. The first stage of aerobic cellular respiration, glycolysis, can be performed without oxygen. However, if oxygen is not present, cellular respiration cannot continue past this stage.
In glycolysis, glucose is converted to a carbon-based molecule called pyruvate. Two molecules of adenosinse tri-phosphate (ATP), a nucleotide that provides energy to cells, are generated during this process.
Explanation:
decreases
Explanation:
According to the general trend, metallic character decrease in proceeding up a group of elements in the periodic table.
Metallic character increases down a group and decreases across the period.
- Metallicity or electropositivity is a measure of the tendency of atoms of an element to lose electrons.
- It is related to electronegativity and ionization energy.
- The lower the ionization of energy of an element, the more electropositive it is
- Across a period, electropositivity decreases.
- It increases down a group on the periodic table.

Answer:
D. Surface tension
Explanation:
surface tension is how much weight something can be on the surface before it breaks... water has a surface tension less than the weight of the paper clip. making it able to float. the paper clip does not break the surface tension of the water
