Answer:

The level of compaction in Eukaryotes from naked DNA to the most compact is:

d. nucleosome, solenoid, looped chromatin (300-nm fiber), metaphase chromosome

Explanation:

As we know that the

  • Diameter of  DNA is 2 nm.
  • Diameter of nucleosome is 11 nm.
  • Diameter of solenoid is 30 nm.
  • Diameter of looped chromation is 300 nm
  • Diameter of meta-phase chromosome is 1400 nm

All of these facts depict that the the least compact is DNA and most compact is meta-phase chromosome.

What two parts of a nucleotide do not ?change throughout the structure of DNA a. Five-Carbon Sugar and Phosphate Group b. Five-C
Stolb23 [73]

Answer:

a. Five-Carbon Sugar and Phosphate

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.

Organisms that eat cows do not obtain a great deal of energy from the cows. In fact, they get less energy than the cows obtain f
marshall27 [118]

Answer:

The cow uses all but stores ten percent of what they eat.

Explanation:

For example, a plant produces 100 percent energy. The plant needs to use the energy for survival.

When a cow eats the plant, it only gains 10 percent of the energy.

Then, say a wolf eats the cow.

The wolf only gets 1 percent of the energy that is produced by the plant.

solong [7]

Answer:

<u>Option -</u> An open circulatory system inside the adults.

Explanation:

  • A terrestrial animal species is discovered with the following larval characteristics: exoskeleton, system of tubes for gas exchange, and modified segmentation. A knowledgeable zoologist should predict that the adults of this species would also feature <u>an open circulatory system</u>.
  • Most of the invertebrates like the insecticides have the open circulatory system, as the system has no specific pathways for the transportation of the materials and other essential nutrients through the medium but they have a more different mechanism in order to provide the sufficient materials to survive.

A person eats a large pasta meal at lunch and then goes for a run before dinner. Explain how the body taps energy from this star
Ilia_Sergeevich [38]

Starches help give you an extra boost of energy during your workout. Starches, as well as sugars, eventually break down into glucose -- your body's main fuel source.

Explanation:

When you eat starchy foods, you'll have a supported energy level over a period of numerous hours. This is separate from sugars, which are simple polysaccharides that give you a quick surge of energy but do blank to keep your energy levels running.
