Answer:
O sinkholes, caves, and hills heating of ground water due to geothermal energy
Explanation:
Answer:
1. 39 J; 2. 3.9 % usable; 3. 96.1 % unusable
Step-by-step explanation:
1. Available energy
Energy consumed = 1000 J
Less waste = - 177 J
Less respiration = <u>-784 J
</u>
Total energy lost = <u>-961 J
</u>
Available energy = 39 J
2. Percent of total energy usable
The chipmunk could use only 39 J of the original 1000 J.
% of energy usable = 39 J/1000 J × 100 % = 3.9 %
3. Percent of energy unusable
The chipmunk lost 961 J of the original 1000 J.
% of energy unusable = 961 J/1000 J × 100 % = 96.1 %
Answer:
BLOOD PATHWAY:
Body > superior and inferior vena cava > right atrium > tricuspid valve > right ventricle > pulmonary semilunar valve > pulmonary artery > lungs > pulmonary vien > left ventricle > bicuspid/mitral valve> left ventricle > Aortic semilunar valve > Aorta > Body
The pathway goes like this:
From the body (we don't say first because this is a cycle), unoxygenated blood collected goes to the heart via the <u>INFERIOR and SUPERIOR VENA CAVA</u> then it empties into the <u>RIGHT ATRIUM</u> from there it passess through a valve called <u>TRICUSPID</u> valve, which prevents backflow of blood to the right atrium. The blood goes to our first pumping chamber, <u>RIGHT VENTRICLE. </u> The right ventricle pumps the blood through the <u>PULMONARY SEMILUNAR VALVE</u> which leads to the <u>PULMONARY ARTERIES</u>, which happens to be the only arteries that carry unoxygenated blood. From there it goes to the lungs to pick up oxygen and rid itself of carbon dioxide. The blood then goes back into the heart via the <u>PULMONARY VEINS</u> and like the latter, they are the only veins that carry oxygenated blood.
The blood then goes back into the heart, emptying into the <u>LEFT ATRIUM. </u> From there it goes through the <u>BICUSPID VALVE or MITRAL VALVE</u> and to the last and thickest pumping chamber, the <u>LEFT VENTRICLE.</u> The left ventricle pumps the blood through the <u>AORTIC SEMILUNAR VALVE</u> which opens out to the <u>AORTA. </u>
And at last, it goes back to your body.
It consists of two major steps: transcription and translation.
- Together, transcription and translation are known as gene expression.
- During the process of transcription, the information stored in a gene's DNA is passed to a similar molecule called RNA (ribonucleic acid) in the cell nucleus.
