Answer:

Statement A - cellular membrane

Statement B - eukaryote

Statement C - spore

Statement D - prokaryote

Explanation:

The cell membrane is a protective layer present around the cell and cell organelle that regulates and allows different molecules to enter and exit to regulate homeostasis.

Eukaryotes are the organism that can be unicellular or multicellular with the cells contain a nucleus in it.

Spores are reproductive cells that has a resistant layer that protects the cell from an unfavorable condition and capable to form an adult.

An organism that is unicellular and lacks the nucleus is known as a prokaryote and bacteria is an example of such organisms.

nydimaria [60]

Answer:

Percentage of glucose that is returned to the muscles.

Explanation:

After intense physical activity, where glycogen reserves are consumed, the muscle acquires its resting and reactivation position, is where the organism that feeds the new reserves for the next physical activity is located.

Foods rich in carbohydrates identified as ATP or glucose in good quantities, but this depends on the amount of intake and the quality of the food, that is how when consuming these sources, the serum glucose values are metabolized, that is, increases glycemia and this promotes the release of insulin that is responsible for generating energy reserves with more complex chemical bonds such as glycogen.

is Earth an open system or closed system? Explain your answer and provide at least one example that occurred during the Precambr
Ivan

Answer:

The Earth is essentially a closed system; it obtains lots of energy from the Sun but the exchange of matter with the outside is almost zero. Isolated systems can exchange neither energy nor matter with an outside system.

The Precambrian was originally defined as the era that predated the emergence of life in the Cambrian Period. It is now known, however, that life on Earth began by the early Archean and that fossilized organisms became more and more abundant throughout Precambrian time.

Which statements about the modification of chromatin structure in eukaryotes are true? Select all that apply. View Available Hin
Kay [80]

The correct answers are:  

  • Methylation of histone tails in chromatin can promote condensation of the chromatin.
  • DNA is not transcribed when chromatin is packaged tightly in a condensed form.
  • Acetylation of histone tails is a reversible process.
  • Some forms of chromatin modification can be passed on to future generations of cells.  
  • Acetylation of histone tails in chromatin allows access to DNA for transcription.

Histone modifications are post-translational modifications of histone protein that can affect gene expression by altering chromatin structure or recruiting histone modifiers.The most common modifications are methylation, phosphorylation, acetylation and ubiquitylation. All of them affect the binding affinity between histones and DNA and thus loosening (gene activation) or tightening (gene repression) the condensed DNA.

Histone methylation is a transfer of methyl group by histone methyltransferases to lysine or arginine amino acid of protein. Effect of methylation depends on the type of protein that is modified. Demethylation is the reverse process.

Histone acetylation is the process of adding of an acetyl group(by  histone acetyltransferases) to histone proteins and it can also activate or inhibit the gene expression. Deacetilation is reverse process.
