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

Answer:

Image result for Explain the technology watney used in the first chapter of the martian

The Mars Ascent Vehicle in "The Martian" is powered by a radioisotope thermoelectric generator (RTG), which converts the heat of the radioactive decay of plutonium-238 into electricity. This RTG is buried a safe distance away from the pioneers' living quarters.

What link in the chain of infection would be broken if there isn't a place for an infectious agent to thrive and reproduce?

just olya [345]

There are six links to the chain of infection, however the reservoir is the correct link to select.

The reservoir includes all the places in the environment where the pathogen or infection lives (this includes people, animals and insects, medical equipment, and soil and water)

explain how the surface area and volume of cell affect the rate of exchange of materials in and out of cells in multicellular or

Shtirlitz [24]

An organism must has a large surface area to volume ratio in order to exchange material easier

in animals erythrocytes have a flat concave shape that allows them to carry more haemoglobin and also increases its surface area to volume ration so that the length and availability of a surface is less for the materials to travel

multi cellular organisms tend to have flat and elongated respiratory surfaces to allow for a higher surface area to volume ratio in order to increase the rate of gas exchange

the ilium in most mammals is flat and elongated and is covered with microvilli to increase surface area and to reduce the cells volume therefore reducing its surface area to volume ratio
hope that helps
