By definition, a body system is primarily comprised of different organs and tissues that work one another to achieve a common body process. These body systems would include:

Circulatory system - concerns with the circulation of blood
Digestive system - breaking down of food particles 
Skeletal system - composed of bone structures serving as our body's framework
Nervous system - composed of nerve cells that responds to different stimuli
Respiratory system - concerns of utilising the entry of oxygen and the exhalation of carbon dioxide.

Answer:

The lithosphere is largely made up of soil, minerals, and rocks—essentially the earth’s crust. A sister to the lithosphere, the hydrosphere contains the liquid parts of the earth.  The cryosphere consists of all frozen water on the earth. Frozen water makes up about 75 percent of the earth’s fresh water. For the atmosphere, the system changes from water to air. The atmosphere is the thin layer of gasses surrounding the planet. The biosphere includes all living organisms, from the bottoms of the oceans to the upper reaches of the atmosphere.

The article describes the former abundance of trees and forests on easter island. describe several factors that contributed to t
tester [92]

1. One of the main reasons for the extinction of the trees in the Eastern Island is the extinction or sudden demise of the birds that carried the seeds to different places. Some of the human activities would have also led to the process of extinction, like the trees were being cut to construct canoes and to use as tools in order to erect statues, and to burn them for warmth.  

2. There was a need to farm the trees and manage them in a proper framework. For example, if one is having 100 trees, then one should use 33 and then plant 33 seeds, and should always keep 34 intact. One should have not used all the trees at once.

Q. A person’s blood glucose level fluctuates during the day, asrepresented in Figure 1. Two hormones, insulin and glucagon,are di
Minchanka [31]

Answer:

If the person has another meal after 5 pm, the glucose level in the blood will increase, and the insulin level too.

Several hours after the meal, the glucose levels will decrease, and the glucagon levels will increase.

Explanation:

When a person ingests another meal after 5 p.m, the glucose levels in the blood will increase, as the body does not need all that glucose right now the insulin levels in the blood will increase to store glucose for later. The glucagon levels after a meal are very low because the aim is to store glucose not use it.

Several hours after the meal, the body needs the energy to keep operating so it will use the glucose that was stored, to do this, the levels of glucagon in blood have to increase and release the glucose, and the levels of insulin in blood have to decrease.

Which of the proposed models for the mechanism of initial transcription suggests that the entire RNA polymerase enzyme moves alo
Degger [83]

Answer:

The right answer is Letter A

Explanation:

The proposed model for the mechanism of initial transcription that suggests the entire RNA polymerase enzyme moves along the DNA is <em>transient-excursion model</em>, and the proposed model that is best supported by experimental findings is<em> scrunching model.</em>

<em>Because RNA polymerase leaves the promoter, translocate a short way along DNA template, synthesizes a short transcript before aborting transcript, releasing the transcript and returning to its original location on promoter. That is the transient-excursion model.</em>

<em>The scrunching model downstream DNA is pulled into the enzyme and has accumulated within the enzyme as single stranded bulges.</em>

<em>Experiments show that scrunching is right, experiments using single molecule analyses that allow the positions of different parts of polymerase to be measured relative to each other and to the template DNA during transcription.</em>
