Describe how the organelles in a cell work together to keep an organism alive​
vodomira [7]

Answer:

These organelles are like the organs in a human and they help the cell stay alive. Each organelle has it's own specific function to help the cell survive. The nucleus of a eukaryotic cell directs the cell's activities and stores DNA. ... All of the cell's organelles must work together to keep the cell healthy.

What are the similarities between nucleotides?
Nonamiya [84]

Nucleotides are organic molecules consisting of a nucleoside and a phosphate.

They serve as monomeric units of the nucleic acid polymers – deoxyribonucleic acid (DNA) and ribonucleic acid (RNA), both of which are essential biomolecules within all life-forms on Earth. Nucleotides are obtained in the diet and are also synthesized from common nutrients by the liver.

Nucleotides are composed of three subunit molecules: a nucleobase, a five-carbon sugar (ribose or deoxyribose), and a phosphate group consisting of one to three phosphates. The four nucleobases in DNA are guanine, adenine, cytosine and thymine; in RNA, uracil is used in place of thymine.

Nucleotides also play a central role in metabolism at a fundamental, cellular level. They provide chemical energy—in the form of the nucleoside triphosphates, adenosine triphosphate (ATP), guanosine triphosphate (GTP), cytidine triphosphate (CTP) and uridine triphosphate (UTP)—throughout the cell for the many cellular functions that demand energy, including: amino acid, protein and cell membrane synthesis, moving the cell and cell parts (both internally and intercellularly), cell division, etc.

How much naoh is needed to prepare 461 ml of solution with a ph of 10.00?
Trava [24]

Answer: -

Volume of NaOH = 461 mL = 461/1000 = 0.461 L

pH = 10.0

Using the relation pH + pOH = 14.00

pOH = 14.00 - 10.00= 4.00

Using the relation

[OH⁻] = 10^{-pOH}

= 10^{-4.00} M

Since NaOH is a monobasic acid,

[NaOH] = [OH⁻] = 10^{-4.00} M

Amount of NaOH = [NaOH] x Volume of NaOH

= 10^{-4.00} M x 0.461 L

= 4.61 x 10⁻⁵ mol

Molar mass of NaOH = 23 x 1 + 16 x 1 + 1 x1

= 40 g / mol

Mass of NaOH required = 4.61 x 10⁻⁵ mol x 40 g/ mol

= 1.84 x 10⁻³ g
