Answer:
Since all forms of bacteria are prokaryotic and in turn unicellular their offspring don’t have to undergo a long period of gestation and growth prior to relative maturity. Whereas any organism (for the most part) in the animila kingdom do and any animal also require a mate. So one major benefit of bacteria being capable of asexual reproduction is they don’t require a mate to reproduce hence the name ASEXUAL. Also, another benefit I vaguely/briefly mentioned is the ability to reproduce at a faster rate than many if not all eukaryotic organisms. For example E.coli a type of bacteria can reproduce in as little as 20 minutes if I recall correctly.
Answer:
The correct answer is E) eutely
Explanation:
Nematodes are organisms with bilateral symmetry, although their organs are coiled, sometimes one of the limbs is lost and many of sedentary life tend to radial symmetry. One of the most striking characteristics of these animals is that their growth is not produced by an increase in the number of cells that compose them, but by an increase in the size of the already existing cells; in fact, in most adult tissues the number of cells is constant, a phenomenon known as eutelia.
Eutelia is the condition of an organism composed of a constant number of cells or syncytial nuclei in all adult individuals of a species, such as nematodes, it means that body growth is not carried out by increasing the number of cells but by the growth of existing cells.
The correct answers are:
b. Human influenza a virus evolves escape variants, resulting in a distinctive cactus-shaped phylogeny.
All types of Human influenza viruses evolve to escape immunity induced by prior infections and vaccinations.
c. Measles experiences strong selection for escape variants, resulting in a phylogeny similar to a nonpathogenic species.
As a result of measles infection, specific antibody and CD4 and CD8 T cell responses are generated and contribute to virus clearance and protection from reinfection.
Answer:
B. The thick, waxy coating prevents water loss.
Explanation:
This is because the thick waxy coating needle refer to structure posses by plants or mostly xerophites plants to adapt to their environment. Plants that grow in area where there is no abundance of water for use normally posses these structures which will reduce evapotranspiration and conserve water. These plants normally have extensive roots to draw water.
Answer:
Technically yes, and no. Read the following:
Explanation:
Stem cells can give rise to specialized cells. When unspecialized stem cells give rise to specialized cells, the process is called differentiation. While differentiating, the cell usually goes through several stages, becoming more specialized at each step.
