respiration:
uses oxygen
releases carbon dioxide into the air
converts food to usable energy
photosynthesis:
produces food for the plant
requires chlorophyll
used carbon dioxide and water
transpiration:
pulls water from roots to the leaves
returns water to the air
important part of the water cycle
sorry if this answer was too late ;)
Answer: Option A
Explanation:
The heterozygous allele can be defined as the condition in which the organism has two different alleles of the gene.
It is represented as Rr, means a capital letter and a small letter. This hows that the organism has one dominant gene and one recessive gene in it.
This dominant and recessive condition decides the genotype and phenotype of organism.
Answer:
Three nucleotide
Explanation:
Three nucleotides are required to code for one amino acid. There are four types of nucleotides A, T, G, C which make DNA. So a doublet of nucleotide code which involves only two nucleotide would be insufficient to code for 20 amino acids because if 4 different nucleotide is taken two at a time then it can only produce 16 amino acid(4²=16).
But if we take three-nucleotide than the number reaches 64 which is more than sufficient to code for 20 different amino acids(4³= 64). Therefore 3 nucleotides are needed to code for an amino acid.
Answer:option C= mRNA
Explanation:
MACROMOLECULES are large molecules, such as protein, commonly created by the polymerization of smaller sub-units called monomers.
The NUCLEAR PORE is a protein-lined channel in the nuclear envelope. The NUCLEAR PORE regulates the transportation of molecules between the nucleus and the cytoplasm. In eukaryotic cells, the nucleus is separated from the cytoplasm and surrounded by a nuclear envelope.
mRNA is synthesized by DNA during a process known as the TRANSCRIPTION. After the synthesis, the new molecule moves from the nucleus to the cytoplasm. It passes through the nuclear membrane through a NUCLEAR PORE. Then, it will later join with a ribosome, which is just coming together from its two sub-units, one large and one small.
