<span>Good Morning!
A natural resource that is extracted from the ground by its valuable mineral content, is called "ore." We have, for example, gold ore, lead ore and galena ore. These materials gain the "ore" next to the name, precisely because it has the economic potential in its extraction.

Answer:
<u><em>C. DNA from the S bacteria is necessary for bacterial transformation to occur.</em></u>
Explanation:
These series of experiments determined that DNA is the genetic material which gives rise to a particular type of cell. As we can see, the S bacteria with degraded proteins were able to grow when the proteins and RNA were degraded. But they were not able to grow when their DNA was degraded. This experiment proved that proteins or RNA are not the genetic material, rather DNA is the material related to inheritance.
The general shape of the epithelial cells that are nearest
to the lumen in an empty urinary bladder is in multiple cell layers which are
considered to be a stratified tissue and the cells in it are shaped in terms of
the organ’s distention. This type of epithelial cell is the transitional
epithelium.
1. Similarities:
they are both processes of cell division by which cells reproduce.
They share several steps of the process(prophase, metaphase, anaphase e telophase, cytokinesis) but meiosis has another division also with those same steps.
In both cases the cell duplicates its DNA by pulling it
apart into two sets, place the sets on each end of the cell, and then
divide down the middle.
Both produce new cells
based on their parent cells' genes.
2. The differences:
Mitosis:
- has 1 division per cycle
- one cell produces 2 new cells
- the genetic information in the mother-cell and the daughter-cells are the same. ( the number of chromosomes is also the same)
- it occurs in somatic cells
Meiosis:
- two divisions per cycle.
- one cell when divides produces 4 new cells
- the new cells have different genetic information. mixes the the genetic material from the
parent cells
- the number of chromosomes of the daughter cells is half of the mother's.
