Remember that weight is calculated as mass * gravity
Explanation:
Weight is the result of the influence of gravity on the mass of an object. Therefore, differences in gravity will cause an object of the same mass to weight differently on a scale. On the moon, an astronaut would weight 1/3 of their weight on earth. This is because the gravity on the moon is approximately 1/3 that on earth. The influence of gravity is also higher the larger the mass of an object.

Answer:
Nitrogen is a very important and needed for plant growth. It is found in healthy soils, and give plants the energy to grow, and produce fruit or vegetables. Nitrogen is actually considered the most important component for supporting plant growth.
Nitrogen in its gaseous form (N2) can't be used by most living things. It has to be converted or 'fixed' to a more usable form through a process called fixation.
Lithospheric Processes cause magmatism, mantle dynamics, and faulting, which in turn shape the Earth's ever-changing surface. We also study the high temperature systems in the Earth's interior that produce magmas, drive metamorphism, and create mantle heterogeneity.
Explanation:
As it gets colder, the molecules get less dense which causes it to get smaller.
Out of the following give choices;
a. All DNA strands
contained only the heavy nitrogen isotope.
b. Half of the DNA strands contained only the light nitrogen
isotope.
c. All DNA strands contained both heavy and light nitrogen
isotopes.
d. All DNA strands contained only the lighter nitrogen
isotope.
The answer is b. Meselson–Stahl experiment demonstrated the semi-conservative model of DNA replication.
When DNA is replicated, one strand of the new double
helix strand is the parent's strand while the other is the newly synthesized
one. This made the semiconservative model stand out over the other two, dispersive
and conservative models.
I would say excretion since that means the process of expelling waste matter.
