Answer:
b. the pressure in the right atrium is greater than in the right ventricle
Explanation:
A bicuspid valve is an aortic valve that only has two leaflets, instead of three. The function of aortic valve is to regulates blood flow from the heart into the aorta. The valve opens and closes because of pressure differences. The opening of the valve occurs when the pressure is greater in the left atrium than ventricle whereas, closing happens when there is greater pressure in the left ventricle than atrium so we can conclude that the pressure in the right atrium is greater than in the right ventricle.
D I’m pretty sure that’s defiantly right
Answer:The predicted population of brain coral in a reef covering 120m² is ; ≈ 40
First step : Calculate the value of the default population density
Population density = population size (dive 1) / total area
= 4 / 12 = 0.33
Total area ;
∑ Area of each reef quadrant = length * width = 2 * 2 = 4m²
∴ Total area = 4 + 4 + 4 = 12m².
Final step : Determine the value of the predicted population of brain coral
Population density = ( predicted population ) / predicted area
0.33 = ( pp ) / 120m²
∴ Predicted population ( pp ) = 0.33 * 120
= 39.6 ≈ 40 brain corals
Hence we can conclude that the predicted population of brain coral is 40
Explanation:
Answer:
d) 2v
Explanation:
Since, root mean square speed of a molecule,
Where,
k = Boltzmann constant,
T = temperature of gas,
m = mass of molecule,
Also, the temperature of a gas,
Where,
p = pressure of the gas,
V = volume,
n = number of moles of gas,
R = universal gas constant,
If V = 2V and p = 2P
Then,
Hence, if rms speed of a gas molecule under initial conditions is v then rms speed of a molecule will be 2v
i.e. option d is correct.
