Answer: Prokaryotic cells do not have a membrane.

It is true that prokaryotic cells do not have a membrane while eukaryotic cells have one strong membrane. Eukaryotes are commonly multicellular compared to prokaryotes that are commonly unicellular. Prokaryotes do not have nucleus while eukaryotes do.

What are histones, and how are they arranged in nucleosomes? Drag the terms on the left to the appropriate blanks on the right t
Eva8 [605]

Answer:

1) c. five

2) a. lysine and arginine

3) g. two

4) d. four

Explanation:

A nucleotide can be defined as an organic molecule which forms the building block of nucleic acid such as deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).

Basically, nucleotide comprises of the following parts;

1. Nitrogenous base: this includes adenine (A), thymine (T), guanine (G), and cytosine (C) which are mainly found in the DNA while adenine (A), guanine (G), uracil (U) and cytosine (C) are found in the RNA.

2. A phosphate group.

3. A penrose sugar: it is either deoxyribose in DNA or ribose in RNA.

The two parts or chemical components of a nucleotide which do not change throughout the structure of DNA are;

I. Five-Carbon Sugar also known as deoxyribose and it has hydrogen on its second carbon.

II. Phosphate: this is the structural backbone that provides support to DNA.

Histones are a group of highly basic proteins that are mainly associated with deoxyribonucleic acid (DNA) in the nucleus of a living organism and then condense it to chromatin.

Histones include five main classes of relatively small basic proteins containing relatively large amounts of lysine and arginine. Nucleosomes are made of two each of four types of histones.

The length of bamboo grows much faster than that of thickness why?​
iren [92.7K]

Using a slow- and fast-growing variant of bamboo, Wei and colleagues looked at cell division, growth, and gene expression (through transcriptomics, which measures all the genes being expressed by an individual) to discover which genes may be responsible for fast growth in bamboo. They found that the slow-growing variant had reduced expression of genes relating to cell wall construction, the plant hormone auxin (important for cell growth and cell division), and had irregular cell growth and cell walls. Wei and colleagues suggest that a reduced ability to produce and perceive auxin, combined with a weakened cell wall, are responsible for the slow growth seen in the bamboo variant.

trapecia [35]

Answer:

The cause is likely Manifestation of dehydration

Explanation:

The hematocrit measures the red cell mass in a 100-mL plasma volume. The hematocrit may be deceptive because it varies with the quantity of extracellular fluid, rising with dehydration and falling with over expansion of extracellular fluid volume. The client is manifesting an abnormal elevation as a result of fluid loss.
