Substances can enter and exit the cell through the membrane through passive or active transport. The processes of endocytosis and exocytosis ensure, respectively, the entry and exit of macromolecules and other particles.

<h3>In which two ways do substances cross the membrane?</h3>

The selective passage of substances across the membrane occurs in two different ways:

active transport, when it involves the use of energy.
passive transport, when it does not involve the use of ATP.

With this information, we can conclude that substances can enter and exit the cell through the membrane through passive or active transport. The processes of endocytosis and exocytosis ensure, respectively, the entry and exit of macromolecules and other particles.

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.
