Answer:
i believe the answer is a or d because it is definitely the stronger prevailing winds
<span>The answer to this question would be: b.)Data should be presented in a clear and organized manner.
The data should be presented in the best way to read it. The original format of the data might be confusing to read. It could be graph or anything that make the reader can understand what point you want to make. Putting the research method also a good idea since the reader might want to verify the research validity before looking the data.
It doesn't have to be presented orally since most of the scientific report will be written.</span>
Answer:
See below.
Explanation:
Let the allele for colour be C (c) and the allele for shape be S (s).
True breeding yellow plant with round seed = CCSS
True breeding green plant with wrinkled seed = ccss
crossing the two;
CCSS x ccss = CcSs (yellow colour with round seeds)
All the F1 offspring are yellow with round seeds (CcSs).
Selfing CcSs to produce F2 generation results in:
9 Yellow, round seeded
3 Yellow, wrinkle seeded
3 Green, round seeded
1 Green, wrinkle seeded.
<em>The inheritance pattern of the two traits follow the law of independent assortment of genes as described by Mendel 2nd law of genetics. Medel stated that characters are inherited independently of one another.</em>

Answer:
Hypertonic
Explanation:
Hypertonic solution is a solution that has higher concentration of solute outside the cell than inside the cell. It has higher osmotic pressure than another solution.
Example is any glucose solution that with a concentration higher than 5%.
The answer is C and the reason is because 1. Interphase:
The DNA in the cell is copied resulting in two identical full sets of chromosomes.
Outside of the nucleus? are two centrosomes, each containing a pair of centrioles, these structures are critical for the process of cell division?.
During interphase, microtubules extend from these centrosomes.
2. Prophase I:
The copied chromosomes condense into X-shaped structures that can be easily seen under a microscope.
Each chromosome is composed of two sister chromatids containing identical genetic information.
The chromosomes pair up so that both copies of chromosome 1 are together, both copies of chromosome 2 are together, and so on.
The pairs of chromosomes may then exchange bits of DNA in a process called recombination or crossing over.
At the end of Prophase I the membrane around the nucleus in the cell dissolves away, releasing the chromosomes.
The meiotic spindle, consisting of microtubules and other proteins, extends across the cell between the centrioles.
3. Metaphase I:
The chromosome pairs line up next to each other along the centre (equator) of the cell.
The centrioles are now at opposites poles of the cell with the meiotic spindles extending from them.
The meiotic spindle fibres attach to one chromosome of each pair.
4. Anaphase I:
The pair of chromosomes are then pulled apart by the meiotic spindle, which pulls one chromosome to one pole of the cell and the other chromosome to the opposite pole.
In meiosis I the sister chromatids stay together. This is different to what happens in mitosis and meiosis II.
5. Telophase I and cytokinesis:
The chromosomes complete their move to the opposite poles of the cell.
At each pole of the cell a full set of chromosomes gather together.
A membrane forms around each set of chromosomes to create two new nuclei.
The single cell then pinches in the middle to form two separate daughter cells each containing a full set of chromosomes within a nucleus. This process is known as cytokinesis.
Meiosis II
6. Prophase II:
Now there are two daughter cells, each with 23 chromosomes (23 pairs of chromatids).
In each of the two daughter cells the chromosomes condense again into visible X-shaped structures that can be easily seen under a microscope.
The membrane around the nucleus in each daughter cell dissolves away releasing the chromosomes.
The centrioles duplicate.
The meiotic spindle forms again.
7. Metaphase II:
In each of the two daughter cells the chromosomes (pair of sister chromatids) line up end-to-end along the equator of the cell.
The centrioles are now at opposites poles in each of the daughter cells.
Meiotic spindle fibres at each pole of the cell attach to each of the sister chromatids.
8. Anaphase II:
The sister chromatids are then pulled to opposite poles due to the action of the meiotic spindle.
The separated chromatids are now individual chromosomes.
9. Telophase II and cytokinesis:
The chromosomes complete their move to the opposite poles of the cell.
At each pole of the cell a full set of chromosomes gather together.
A membrane forms around each set of chromosomes to create two new cell nuclei.
This is the last phase of meiosis, however cell division is not complete without another round of cytokinesis.
Once cytokinesis is complete there are four granddaughter cells, each with half a set of chromosomes (haploid):
in males, these four cells are all sperm cells
in females, one of the cells is an egg cell while the other three are polar bodies (small cells that do not develop into eggs).
