The injury to Kevin’s right cerebral hemisphere could affect
the strength and movement on the left side of his body, as the right half of
the brain controls the left side and vice versa. Reasoning, attention, perception,
social communication and memory are also controlled by the right side of the
brain and these functions could also be impaired from an injury to his right
cerebral hemisphere.
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.
Vesicles form naturally during the process of secretion(exocytosis), uptake (phagocytosis and endocytosis) and transport of materials within the cytoplasm. Alternatively, they may be prepared artificially, in which case they are called liposomes.
