Explanation:
Organisms don’t have to only reproduce sexually or only reproduce asexually - some animals do both!
When conditions are good, such organisms will reproduce asexually because it is easier. For example, starfish (by fragmentation), slime molds, and water fleas/daphnia (by parthenogenesis) all reproduce asexually when there is plenty of food, minimal predators, and not too much crowding of individuals of the same species.
When conditions worsen (less food, too many individuals, etc), they may switch to sexual reproduction in order to add genetic variation to their population and ensure survival through difficult times.

Answer:
a. True
Explanation:
Ribosomes are ribonucleoprotein complexes composed of RNA and proteins, which have two main roles 1-decode the message of the messenger RNA (mRNA) molecule and the formation of peptide bonds in the protein. For this purpose, each triplet of nucleotide bases or 'codon' in the mRNA sequence is used to assemble specific amino acids in the nascent polypeptide chain. Although different, both prokaryotic ribosomes and eukaryotic ribosomes are composed of two subunits: one small subunit that decodes the mRNA into a specific amino acid chain, and one large subunit that forms the peptide bonds in the polypeptide chain. Each ribosomal subunit is in turn composed of ribosomal RNAs and proteins. These ribosomal RNAs act as scaffolds by combining with proteins that assemble into ribosomes (i.e., small and large ribosome subunits).
Answer:
What color light is best absorbed by chlorophyll?
As shown in detail in the absorption spectra, chlorophyll absorbs light in the red (long wavelength) and the blue (short wavelength) regions of the visible light spectrum. Green light is not absorbed but reflected, making the plant appear green. Chlorophyll is found in the chloroplasts of plants.
Explanation:
therefore it is blue
