Answer:
A. Haploid (n)
Explanation:
Conifers do not exhibit double fertilization that forms triploid (3n) endosperm in flowering plants.
Endosperm in conifers develops from the haploid cell of female gametophyte before fertilization. Since the endosperm is formed by the mitotic divisions in the haploid cell (n) of female gametophyte, it is haploid (n) in nature.
Answer:
Selective Optimization With Selection.
Explanation:
It is known that this theory was widely known from 1980s and was postulated by a man called Baltes. Baltes here argued that as individuals advance through life they are increasingly faced by age related deficits which place limits on their cognitive and behavioral resources. Tackling these limits placed on domains, individuals will begin to invest resources into particular styles and behaviors that are deemed adaptive to the new constraints.
Answer:
To carry out these functions, DNA sequences must be converted into messages that can be used to produce proteins, which are the complex molecules that do most of the work in our bodies. Each DNA sequence that contains instructions to make a protein is known as a gene.
Explanation:
Answer: B. The bacteria must adjust to the nutrient content in the new medium, synthesizing necessary amino acids, growth factors, and enzymes.
Explanation: The lag phase is a time for adjustement to new environments, in this case new mediums. In that phase, bacteria sense the available nutrients to synthesize those required and grow as preparing for division, metabolizing to produce energy, making proteins, fatty acids, etc.
False because they don't get anything from the farms
