The term applied when water passes through a selectively permeable membrane from an area of high to low concentration is called osmosis. Osmotic pressure is defined as the amount of external pressure that is required to stop the net movement of the solution across the semi permeable membrane. In terms of biology, osmosis has great importance as most of the membranes in our body are semi permeable. Permeability depends on several factors such as charge, solubility, solute size and chemistry. Osmosis is the process that provides the primary means through which water travels in and out of the cells.

<h3>What are evolutionary trees?</h3>

Evolutionary trees are trees that help to arrange and reconstruct the evolutionary history of species or groups of organisms belonging to either genera, families, or orders. The trees reconstruct and show case two form of information that is related to evolutionary change, cladogenesis and anagenesis.

Therefore, They aren't all the same is not true of evolutionary trees.

Part A - Modification of chromatin structure Which statements about the modification of chromatin structure in eukaryotes are tr

Salsk061 [2.6K]

Answer:

Some forms of chromatin modification can be passed on to future generation of cells

Acetylation of histone tails in chromatin allows access to DNA for transcription

DNA is not transcribed when packaged tightly in a condensed form

methylation of histone tails can promote condensation of the chromatin

Explanation:

chromatin modifications that can be passed on includes epigenetic modifications that are heritable changes made to the chromatin structure that does not involve the DNA sequences. Some epigenetic modifications include DNA methylation and Histone modifications. examples of histone modification include acetylation, methylation, phosphorylation, ubiquintylation etc. All these function either in allowing the DNA become more accessible to transcritional factors or vice versa. for exmple, histone tail acetylation encourages unwounding of nucleosomes allowing transcriptional factors to have access to the DNa while histone tails methylation further tightens the nucleosomes promoting condensation of the chromatin.

RideAnS [48]

Answer:

With respect to the cell wall of fungi and plants, it is correct to state that both cell walls provide structural support but fungi is made of polysaccharides and chitin and plants are made of cellulose.

Explanation:

The cell wall is the most external structure of the cells of fungi and plants, giving them form and protection, at the same time that it allows the growth and the function of relation between cells and of these with respect to its environment.

the main difference between the cell wall of fungi and plants is its composition, being in the first ones chitin and glucosamine. In plants, the main component of the cell wall is cellulose.
