Correct answer choice is :
A) True
Explanation:
Lipoproteins are essentially a hub full of fat and cholesterol, along with a lipid layer that includes proteins named apolipoproteins. There are many kinds of lipoproteins, but the two most prominent ones are called Low-Density Lipoprotein and HDL.LDL particles are seldom related to as bad lipoprotein because of concentrations, dose-related, associated with atherosclerosis change. High-density lipoproteins (HDL) get fat molecules from the body's cells and take it back to the liver.
Humans get their energy from eating and sleeping.
Answer:
C. relatively large size
Explanation:
Earth's internal heat flow to the surface is 80% due to mantle convection while the remaining heat mostly originates in the Earth's crust and about 1% due to volcanic activity, earthquakes, and mountain building.
The earth's internal heat- stresses between the lithosphere and the upper mantle are responsible
for geological processes. These stresses are the results of motions in the upper mantle stemming from convection that push the lithosphere in different directions.
Larger planets cool slower than small planets.
Answer:
16J
Explanation:
From hookes law
The work done in a spring is given as W =1/2ke^2
Given that the force constant (k) is constant in the spring material
We have that 2W = e^2
Let W1 = 4J e1= 2cm e2 = 4cm
Let W2 be the work required to stretch it an additional 4cm
W1/ W2 = e1^2/e2^2
W2 = W1* e2^2 / e1^2
= 4* 4^2 /2^2
=4× 16 / 4
= 16J
