<span>West Nile virus is mostly spread through infected mosquitoes, which is likely how these other patients were infected. Other possible but unlikely ways include blood transfusions and organ transplants, so the physician would likely be able to track down whether Peter donated any blood during his recent hospital visits.</span>
One critical observation used by both Lamarck and Darwin in their research is about characteristics of inheritance. Although each claimed different sources of inheritance, they were in unison that in time, individuals acquire characteristics called inheritance. Lamarck believed that inheritance is passed from parents to offspring, while Darwin thought that it’s a product of natural selection.
Answer:
The endomembrane system includes the nuclear envelope.
Explanation:
The endomembrane is composed by the endoplasmic reticulum (ER) and the golgi apparatus. Its main function is to synthesize proteins (rough endoplasmic reticulum studded with ribosomes) proteins can also be modified in the ER of pass to the golgi apparatus where they can be modified and sort to be packed in vesicles to be exported to different parts of the body, for example hormones.
the nuclear envelope only holds the DNA and it´s not involved in protein synthesis.
Answer:
A red blood cell, sitting in the right atria of the heart is chocolate-brown in color since its a deoxygenated red blood cell with carbon dioxide rather than oxygen in its hemoglobin.
First
The tricuspid valve pumps it through the right ventricle
Secondly
pulmonary valve pumps it from the right ventricle to the pulmonary circulation.
Then
In the alveoli of the lungs, gas exchange occurs during pulmonary circulation
The end product is oxyhemoglobin( bright red colour) I.e oxygenated blood
The next step
pulmonary veins is the means whereby the red blood cell go to the left atria from the pulmonary circulation through the aortic valve
to mitral valve then to the aorta and systemic circulation
Therefore
oxygen is replaced by carbon dioxide during systemic circulation indicating a end to cellular respiration
Lastly
It's transported back to the right atrium of the heart completing the cardiac cycle.
