Hey Taonga! Tropism involves an organism (mainly plant) growing toward or away from a stimulus. Taxis involves an organism (protist or animal) moving toward a stimulus.
This happens early in embryonic development in females, where one of the two X-Chromosomes is randomly (and permanently) inactivated, as you said, in cells other than egg cells.
This phenomonon is actually called X-Inactivation.
X-Inactivation make sure that females, just like males, have a single functional copy of the X Chromosome in each and every one of their cells in their body.
Glad I could help, byee now
Osmosis only talks about water molecules
Diffusion talks everything other then the water molecules.
So,
Osmosis : water molecules travel from a region of a higher water potential to a region of lower water potential through a partially permeable membrane via osmosis
Diffusion : Travels from a region of higher concentration to a region of lower concentration through a partially permeable membrane via diffusion
4 cells will result. Each cell will have 20 Chromatids which is half a chromosome. once sexual reproduction takes place, these 20 chromatids will match with those from the other parent cell to form chromosomes
In simple terms, Gene expression can be stated as the process by which the heredity details in a gene sequence a be made into a functional gene.
<u>Explanation:</u>
- The odd one for this question is probably would be "it occurs because of cellular signals within your body".
- It explains how a cell functions. In Gene expression, the gene encodes the protein and the message from DNA to RNA gives the cell functions.
- It is the specific combination of genes that are turned on or off. It can be stated as the process of turning off and turning on, it acts as a switch to on and off it is known as the gene expression or gene regulation.
- It creates different DNA within each of your cell types. The unique design of gene expression results in unique and different combinations of proteins and makes each cell types.
