DNA or deoxyribonucleic acid is known to be the genetic material for almost all organisms. It is tightly packed within the nucleus of every cell and wraps around the unique proteins known as histone. These histones form the loops of DNA called nucleosomes.

Further Explanation:

The genetic information is known to be packaged in 23 sets of chromosomes. In these, histones which are the proteins that aid the molecule of DNA to be very tightly packed in added and also aids in maintaining the double-helical structure of the DNA.

The thread-like structure provided in the diagram is known as chromosome. Chromosomes are found in the nucleus and it is composed up of protein as well as single molecule of DNA. The bunch like structures present is known as nucleosomes that are considered to be the basic unit of the DNA packaging.

The histone units make the structural units of the nucleosome and these units and bounded in the tight helical fiber. Finally, is the structure of DNA, which is known to be the genetic material.

I assume this photo has the labels you are talking about.

DNA double helix consists of two strands that wind around each other with their nucleotides liked.-> it's the structure number 5
nucleosome- it's a segment of DNA wound in sequence around eight histones (proteins)- number 2
Histone- proteins with DNA around them, forming the nucleosome- number 4
Tight helical fiber- chromatin coiled very tightly- 3
Cromosome- chromatin condensed even tighter forming a X shape.- 1

Which of the following is an abiotic factor that limits the carrying capacity of animal species?

Nata [24]

Answer:

Should be D. Breathable gases

Explanation:

The carrying capacity of an environment is the maximum population size of a biological species that can be sustained by that specific environment, and abiotic factors are non-living chemical and physical parts of the environment that affect living organisms and the functioning of ecosystems.

Which trophic level of a marine food chain breaks down organisms from all of the other levels?

Sonja [21]

Decomposers break down the dead decaying body parts of all other organisms. They are also known as saprophytes. Apart from this, the top consumers like sharks, dolphin etc. eat away the smaller trophic organisms like squids, fishes etc,. But after the death of the tertiary consumers, they are also decomposed by the decomposers.
