Research has demonstrated that neural stem cells have an impaired ability to differentiate into functional neurons when subjected to ethanol. They found out that treating cultured neural system impairs their ability to differentiate in functioning neurons. With this impairment it seems to be united with aberrant, dense methylation and loci which are active in normal tissue.
Answer:
D) Competition between organisms
Explanation:
Random mating between organisms, absence of any factor of evolution (mutation, recombination, gene flow, migration etc.) and a large population size serve to maintain the allele frequency and thereby the phenotype frequency over generations. However, competition between organisms for any natural resource leads to natural selection of "better competing organisms" and increases their phenotype frequency in the population.
Answer:
Options B and C
Explanation:
Living things can be divided into three domains: archaea, bacteria and eukarya
The domain "eukarya" includes kingdom fungi, plantae, and animalia
A Fungus is any member of the kingdom Fungi. Fungi are eukaryotic organisms typically having chitin cell walls but no chlorophyll or plastids. Fungi may be unicellular or multicellular. Examples of fungi are mushroom, yeast, mucor etc
Plants are multicellular eukaryotic organisms that have double-membraned chloroplasts in its cells containing chlorophyll.
Animals are multicellular organisms that is usually mobile, whose cells are not encased in a rigid cell wall (distinguishing it from plants and fungi) and which derives energy solely from the consumption of other organisms (distinguishing it from plants).
Answer:
A. Sexual reproduction
Explanation:
A multicellular organism is made up of more than one cell. Humans, animals, and plants are all examples of multicellular organisms. Groups of cells form tissue, groups of tissue forms organs, groups of organs form systems.
Unicellular organisms receive material directly from their environment. Multicellular organisms have systems for moving materials throughout their body. Unicellular organisms can perform all of life’s functions within a single cell. Multicellular organisms have many cells that each perform a special function. Cells develop into their mature forms through the process of cell differentiation. Cells differ because different combinations of genes are expressed. Organs are groups of tissues that perform a specific or related function. Organ systems are groups of organs that carry out similar functions.
For example, stem cells are classified into three types: totipotent (or growing into any other cell type), pluripotent, or growing into any cell type but a totipotent cell), multipotent (or growing into cells of a closely related cell family).
