<em>1.) True</em>

<em>The reason this is true is because adjusting the camera allows you to get an understanding of how someone else should look or how they would likely look best when photographed. It also gives an understanding of how a camera should be aimed to get the best result.</em>

<em>2.) True</em>

<em>While many cameras have this feature, most are configured to only use this feature when the photographer selects it. This feature allows the photographer to adjust the camera in case they feel something isn't quite right with it, and it also allows them to get into the picture themselves if they feel they want to. </em>

<em>Hope this helps you, and have fun with whatever it is you are doing with your camera.</em>

The value of ∆G for a chemical reaction taking place in an organism is −255 kJ. Which of the following best describes how this w
Sladkaya [172]

Answer:

D. The reaction will release energy the organism can use to do work.

Explanation:

A negative ∆G means that the products have less free energy than their reactants. This energy had to go somewhere, it can't just disappear. That means that 255kJ of energy was released, turning into free energy for the organism to use for work.

andre [41]

The correct answer is option C, For more kingdoms were introduced

Linnaeus  was the first to develop a system of classification of living things. He mainly grouped the living things into animal or plant kingdom, but later with the advent of microscope it became easy for the researchers to observe microscopic beings and thus three new kingdoms were proposed namely- fungi, protists (considered as simple organism) and monera (bacteria).  

Not only this with in a kingdoms comes several phylum, these phylums were also reorganized and recategorised based on the discovery of more categories and subcategories.

1. on the trace above
ser-zykov [4K]

Answer:

1. when there is cardiovascular disease.

2. High blood pressure increases the likelihood of suffering a stroke, a heart attack, heart failure, kidney disease or premature death.

3. The mitral valve opens.

Explanation:

1. High blood pressure is a common condition in which the force exerted by blood against the walls of the arteries over the course of time is high enough to cause you health problems such as heart disease. After the first rise of pressure caused cardiac ejection volume, one notch occurs with a second ascent product of the reflection of the pulse wave. In younger individuals, with elastic arteries, said wave occurs in diastole, so does not influence the peak systolic pressure. By contrast, with advancing age and the stiffness of large vessels, the reflected wave is transmitted prior to the aorta (systole) so as to increase the peak central PAS.

2. The pressure increases progressively the pressure of the blood flowing through the arteries. As a result, you can submit the following: Arteries damaged and narrowed. High blood pressure can damage the cells of the inner lining of the arteries.

3. When the pressure in the left ventricle falls below the pressure of the left atrium, the mitral valve opens, and the left ventricle fills with blood that had been accumulating in the left atrium.
