Which best explains the role of plants in the nitrogen cycle?
Answer:
Assimilation
Explanation:
This is how plants get nitrogen. They absorb nitrates from the soil into their roots. Then the nitrogen gets used in amino acids, nucleic acids, and chlorophyll. ... When a plant or animal dies, decomposers like fungi and bacteria turn the nitrogen back into ammonium so it can reenter the nitrogen cycle.
This animal DOES NOT have live birth, instead this animal...?
Answer:
The platypus is one of only five species of monotremes in the world. These are mammals that lay eggs instead of giving birth to live young.

How does the structure of DNA explain chargaff's rule?
Answer:
Chargaff's rules state that DNA from any species of any organism should have a 1:1 stoichiometric ratio (base pair rule) of pyrimidine and purine bases and, more specifically, that the amount of guanine should be equal to cytosine and the amount of adenine should be equal to thymine
Chargaff's Rule explains that in the natural DNA, the total number of guanine equals to the number of cytosine and the total number of adenine equals to the number of thymine. This tells about the base pair composition of DNA molecule.
What is Chargaff's rule?Chargaff's rule states that in the DNA molecule of any species or organism, the total amount of guanine residues should be equal to the amount of cytosine residues and the amount of adenine residues should be equal to the amount of thymine residues. A stoichiometric ratio of 1:1 of purine and pyrimidine bases i.e., A + G = T + C should be fulfilled.
Chargaff's rule describes the ratio of the various nitrogenous bases present in the DNA molecule. It aids in the determination of the structure and composition of DNA in living organisms. It is constant for a species.

Which of the following is a chemical reaction?
A. Water freezes.
B. Sugar dissolves in water.
C. Salt and pepper are mixed in a dish.
D. Iron rusts.
Answer:
i think it is d
Explanation:
sorry if wrong
Answer: D. Iron rusts
Explanation: Rust is made from different chemicals in the air that come in contact with said metal. That could be acidic rain for example. Water freezing is only changing temperature. Sugar dissolving is breaking down molecules. Salt and pepper mixed in a dish is a physical change (also that's just plain evil to some people but that isn't the point). Your answer will be D. Iron rusts.

Calculate the mass of an object whose weight is 400 N and acceleration due to gravity is 10 m/s2
Answer:
40kg
Explanation:
F=M*A
M=F\A
M=400\10
M=40kg
The mass of an object whose weight is 400 N and acceleration due to gravity is 10 m/s2 is 40 kg.
What is acceleration due to gravity?The net acceleration that objects get as a result of the combined action of gravity and centrifugal force is known as the Earth's gravity, or g.
It is a vector quantity whose direction, strength, or magnitude match a plumb bob.
According to Newton's second law, an object's acceleration is inversely proportional to its mass and directly connected to the net force. An object's acceleration is determined by two factors: force and mass.
We know that,
F = m x g
m = f/g
Where,
F = force
m = mass
g = acceleration due to gravity
Given that,
F = 400N.
g = [tex]10m/s^2[/tex]
So,
m = 400/10
m = 40 kg.
Thus, the mass is 40 kg.

Describe the process of absolute dating as it relates to igneous rock and the fossil record.
Answer:
Radiometric dating. Geologists use radiometric dating to estimate how long ago rocks formed, and to infer the ages of fossils contained within those rocks. ... When molten rock cools, forming what are called igneous rocks, radioactive atoms are trapped inside. Afterwards, they decay at a predictable rate.
which describes a difference between a positive and negative feedback loop?
a. the output of a system stimulates another cycle of the system only in a positive feedback loop.
b. the output of a system keeps conditions within the body absolutely constant only in a negative feedback loop.
c. the output of a system maintains conditions around a set point only in a positive feedback loop.
d. the output of a system signals the system to disregard the stimulus only in a negative feedback loop
Answer: b. the output of a system keeps conditions within the body absolutely constant only in a negative feedback loop.
Explanation:
In the negative feedback loop, the feedback reduces the excessive response of the stimulus for example regulation of body temperature, and control of blood glucose level. In the positive feedback loop, the response of a stimulus is intensified. Example, positive feedback is the childbirth and blood clotting. According to the negative feedback loop the output of the system keeps the internal body environment constant with respect to the changes in the external environment hence, maintains the homeostasis.
Answer:
b. the output of a system keeps conditions within the body absolutely constant only in a negative feedback loop.
