Answer:
Polymers are broken down into monomers in a process known as hydrolysis, which means “to split water,” a reaction in which a water molecule is used during the breakdown
Explanation:
Answer:
three properties of rocks are;
- they are hard
- they have shape and size
- they have different texture.
Answer:
The reason is probably so that each can fit equally well onto the ribosome and carry out its function
Explanation:
The three-dimensional structure or tertiary structure of tRNAs is conserved and crucial for the interaction : it is L-shaped 3D structure that allows them to fit onto the ribosome (its P and A sites). This is important for the function of tRNA: to be link between mRNA (carries the information from DNA) and ribosome (performs protein synthesis-translation).
Answer:
D. Sterility Locus
Explanation:
Angiosperms have several mechanisms to prevent self-pollination due to the advantage of cross-pollination. One of such mechanisms is self-incompatibility genes present on the sterility locus.
These genes determine the germination of the pollen on the stigma. If both the pollen and stigma carry the same allele of the gene present at the sterility locus, the germination of pollen is prevented.
The sterility locus has multiple alleles and the presence of the same alleles at the same locus in both pollen and stigma prevents the pollen germination.
For example, pollen from S1S2 individuals can not germinate on the stigma with the S1S3 genotype. Here, the pollen does not obtain water as required for germination from the stigma and are unable to germinate.
Biosphere is one of the layers surrounding the earths surface where life exists. It represents the ecological system intergrating living things and their interactions with the environment relating to the other layers (hydrosphere, atmospheres, geosphere and the lithosphere). Photoautotrophs are organisms that make their own food using sunlight in a process called photosynthesis. They are responsible for the food supply in the biosphere.
