In 1838, Matthias Schleiden published his observation that plant tissues are composed of cells. A year later, Theodor Schwann pu

There are 3 parts of cell theory: all living things are made up of cells, all cells come from pre existing cells, and the cell is the basic unit of life. S<em>ince Schleiden and Schwann’s experiments proved that certain tissues were made up of cells (and those tissues are from living organisms), it most closely relates to the part that all living things are made up of cells. Hope this helps! (Also I apologize for the text going italic I’m not sure why it happened)</em>

Hypertonic environment

<h3>How do salts and sugars preserve food?</h3>

Salts and sugars work to preserve foods by creating a hypertonic environment. Salt and sugar will remove the water from the bacteria or fungi and they will not be able to proliferate. Loss of water results in plasmolysis, or cytoplasmic shrinkage.

<h3>What is hypertonic solution and plasmolysis?</h3>

Compared to another solution, a hypertonic solution has a higher solute concentration.

Plant cells subjected to hyperosmotic stress frequently exhibit plasmolysis as a reaction. The live protoplast violently separates from the cell wall as a result of the loss of turgor. The vacuole is primarily responsible for the plasmolytic process.

What is DNA, and how does it function in cells?
Tom [10]
DNA, short for deoxyribonucleic acid, is present in the nucleus of eukaryotic cells and floats around in the cytoplasm of prokaryotic cells. DNA produces blueprints which RNA carry out to ribosomes to code for protein. You can say that DNA passes genetic material through generations.

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.

Alona [7]

If your body has developed a tolerance to a medication you're taking, it means the medication at your current dose has stopped working as effectively as it once did. It might mean your body becomes used to the medication, and you don't get the same benefits or effects as before. Drug tolerance is indicative of drug use but is not necessarily associated with drug dependence or addiction. The process of tolerance development is reversible and can involve both physiological factors and psychological factors.
