The second answer
Temperatures up high need to be warmer near the surface, surface air needs to be humid
Answer:
An amino acid can be encoded by more than one codon.
Explanation:
Codons are triplets of nucleotides in mRNA that are used for the protein synthesis (translation). A codon specifies a single amino acid, but there are exceptions. tRNA molecule contain anticodons, triplets of nucleotides that are complementary to codons. So, during the translation, tRNA carries the amino acid, that corresponds to the codon in mRNA.
Degenerate genetic code (more than one codon can code for the same amino acid) is important, because when point mutation occurs it is possible that the amino acid remains unchanged.
Answer:
3.Fitness is related to whether an organism's adaptations result in more offspring
Answer:
The relationship between cell division and cell growth is that cell division needs to occur for the cells to divide and grow individually.
Explanation:
cell division refers to the process by which the mother cells divides into two daughter cells and cell growth refers to the process by which the size of the cell increases as it grows. They are two different but important and interlinked processes in the cell cycle. They depend on each other as failure in one will lead to failure in the other process too. The cell needs to grow proper in order to divide and create more cells.
Answer
RIBOSOMES on the ROUGH ENDOPLASMIC RETICULUM
Explanation:
This is the site of protein synthesis usually find attached to the rough endoplasmic reticulum or freely on the cystosol,
When they are attached to the endoplasmic reticulum they appeared as back dots which makes the surface of ER to appear rough, hence the name ROUGH ER. Smooth ER, lacks Ribosomes, and therefore appears smooth,
Ribosomes are made up of PROTEIN AND RNA.
They are 25nm in diameter;when viewed under high magnification, where theymade up of two sub-units the small and large units.
The protein synthesize by the Ribosomes are passed into the sacs of Rough E.R for transportation,
Basically, a complete Ribosomes is refereed to as 70S for prokaryotic ribosomes and 80S for Eukaryotic Ribisomes.This refers to their sedimentation Co-efficient in Svedberg units,the Eukaryotes sediment faster than the Prokaroytes
