Because cell wall made up of most cellulose while cell membrane the outer if the animal cell
Kidney, ureter bladder and urethra
Answer:
mRNA: Carry genetic information from DNA to protein; serve as template for protein synthesis.
tRNA: Serves as adapter molecule and deliver specific amino acid from the cell pool to the mRNA-ribosome complex.
rRNA: Structural component of ribosomes.
Explanation:
There are three types of nongenetic RNAs: mRNA, tRNA, and rRNA.
1. The messenger RNA (mRNA) is formed by the process of transcription in the nucleus. Transcription uses template strand of DNA to specify the nucleotide sequence in mRNA. The mRNA enters cytoplasm to join ribosomes. The nucleotide sequence of mRNA serves as a template and specifies the amino acid sequence of proteins.
2. The transfer RNA (tRNA) serves as an adapter molecule during the process of protein synthesis and binds to the specific amino acids to deliver them to the protein-synthesizing machinery. The anticodon of tRNA binds to the complementary mRNA codons.
3. The ribosomal RNA (rRNA) serves as structural components for ribosomes. Each of the subunits of ribosomes is made up of rRNA and proteins.
Answer:
A)Fixation. Nitrogen in its gaseous form (N2) can't be used by most living things
B) it can not be used because it most be converted or, ’fixed’ to a more useable form. To do this it goes through a process called fixation.fixation is the change in a gene pool from a situation where there exists at least two variants of a particular gene (allele) in a given population to a situation where only one of the alleles remains.
C) This form can be made more usable if it’s converted. It has to go through the process of fixation so the gene pool changes.
Explanation:
Answer:cellular respiration is a process by which cells use oxygen to produce energy from food.
This happens in the mitochondria
