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 <span>coiled very tightly- 3
Cromosome- </span><span>chromatin condensed even tighter forming a X shape.- 1</span>

During what stage does land get ready for the arrival of a new species
34kurt

Answer

           The correct option is B.

Explanation

          Ecological succession of any species is composed of following stages:

A. Migration

            The movement of species from one place to another location for the purpose of setting permanently o temporary is known as migration . Forexample

             Siberian crane (<em>Leucogeranus leucogeranus</em>) that live in the arctic tundra of eastern and western Russia. The eastern population of birds migrate to china while western population of these birds migrate to Iran, India and Nepal during winter season.

B. Ecesis

         The complete establishment of species in new habitat that was completely barren or left barren due to some catastrophe is known as Ecesion. This process is dependent upon the climatic, edaphic and biotic factors. The success of plant depend upon some of the adaptations to withstand the unfavorable conditions which includes both biotic and abiotic conditions.

Forexample

               The process of succession in xerosphere start on barren area from pioneer stage covered by crustose lichen, then foliose lichen followed by moss stage, herbaceous stage and a last by shrub stage.

C. Nudation

       The initiation of new species by major environmental disturbance such as volcano eruption is known as Nudation.

D. Reaction

            It represents the effect of established species on the habitat. Forexample plants alter habitat condition as they grow. They extract raw materials from the environment in large amounts and return metabolic wastes. The waste accumulates in large amounts and differ from the original raw materials, thus altering the environment.  

E. Competition

             The phenomenon which involves struggle for existence between two or more individuals growing in same area, that make excessive demand that are similar in nature on the soil is known as competition.

Such struggle may be in between same species or different species. The competition may be interspecific or intraspecific. Because of completion the weak individuals are eliminated as strong ones are retained.

The most biologically devastating oil spills in the marine environment are usually a result of?
lions [1.4K]

The most biologically devastating oil spills in the marine environment are usually a result of the sinking of oil tankers.

An oil spill is a type of pollution that occurs when a liquid petroleum hydrocarbon is released into the environment, particularly the marine ecology.

Oil releases into the sea or coastal waterways are generally referred to as marine oil spills, however land-based spills are also possible.

Oil spills can result from crude oil discharges from tankers, sinking of oil tankers, offshore platforms, drilling rigs, and wells as well as refined petroleum products (like gasoline and diesel) and their byproducts, heavier fuels used by big ships like bunker fuel, or the spill of any oily waste or garbage.

The deep palmar veins drain into the radial and ulnar veins; then those veins, along with the anterior crural interosseous vein,
galina1969 [7]

Answer:

Brachial vein.

Explanation:

Veins may be defined as the blood vessels that carries the blood towards the heart. The main function of the vein is to carry the deoxygenated blood into the heart.

Brachial vein is the deep veins that has the name as their arteries occupy. The brachial veins receive their blood from the palmar veins with the interosseous vein. The brachial veins include the ulnar vein, radial vein in upper limb and lower limb consists of popliteal veins.

Thus, the answer is brachial veins.
