Answer:
The gametophyte is green and nutritionally independent in mosses, liverworts, and fern.
Explanation:
The gametophyte is the sexual stage of growth in plants and algae.
During this stage, there is production of reproductive organs which produce sex cells.
During this stage, the gametophyte is independent since it relies fully on itself for food production.
The presence of chlorophyll enables this independence.
The gametophyte produces its own food through photosynthesis.
What determines the chemical properties is : color, hardness, luster, crystal forms, density, and cleavage.
Answer: 20 amino acids
Explanation:
The Genetic code permits the triplet nature of codons whereby three nucleotides from Adenine, Uracil, Guanine and Cytosine on the messenger RNA (mRNA) join to form 64 codons.
Since more than one codon can specify for an amino acid, the 64 codons then specify for 20 amino acids, that then form the sequence of various proteins
its d because if you get rid of trees then your gettign rid of homes and its increses soil erosion from there being no roots of trees decresed biodiversty form the lack of homes and decresed quality of air because theres no trees to make oxygen
