Cellular metabolism
Explanation:

Answer:
D. rigidity and shape that's why in plants they stand upright for photosynthetic process.
Answer:
smooth was dominant over that for wrinkled
Explanation:
In complete dominance, a gene may have two different variants or 'alleles', dominant and recessive. A dominant allele is a gene variant that is able to produce a certain phenotype, even in the presence of other alleles, while a recessive allele is a gene variant that is masked by the dominant allele in heterozygous individuals (i.e., individuals that inherited different alleles from each parent). By crossing smooth and wrinkled pea plants, Mendel observed the offspring (F1) were smooth rather than mixed, indicating one type of seed texture was dominant over the other. Subsequently, Mendel observed that alleles for different traits (e.g., seed texture and seed color) assorted independently during meiosis.
Answer:
Biosphere
Explanation:
The biosphere is the part of the earth that supports life forms. It includes hydrosphere, atmosphere, and lithosphere. Various ecosystems, aquatic or terrestrial, are present in the biosphere. Biotic and abiotic components of a geographical region that interact with each other together make an ecosystem.
The biotic component of an ecosystem includes all the organisms present in it. Organisms may be unicellular or multicellular. All the organisms are made up of one or more cells. Cells are made up of various biomolecules that interact and enable cells to perform the life processes.
Explanation:
charles darwin proposed thoery of natural selection.he had collected imnumerable specimens of plant and animals.he published concept survival of fittest. while explaining he says that There is always competition for food.only those organism survive which shows adptations in various reasons. it thoery of natural selection.
There are some objections,
1. natural selection is not only factor responsible for evolution.
2. darwin did not mention uesful and useless modifications.
3. There is no explanation about slow and abrupt changes
