Answer:
the answer is D.
Explanation:
The heritable variation is defined as the variance of the breeding values among individuals.
Answer:
Law 2
Explanation:
Newton's Second Law of Motion states that the acceleration of a physical object is directly proportional to the net force acting on the physical object and inversely proportional to its mass.
Mathematically, it is given by the formula;
Hence, Law 2 might require you to do some math calculations.
For example, an object having a mass of 20kg is pushed by John and it then accelerates down the inclined plane at a rate of 0.5m/s². Find the force applied on the object.
Given the following data;
Mass = 20kg
Acceleration = 0.5m/s²
To find the force;
Force = mass * acceleration
Substituting into the equation, we have;
Force = 20 * 0.5
Force = 10 Newton.
Answer:
I think it is C but I'm not 100% sure
The statements that describe steps taking place in the nitrogen cycle are
- Many biotic and abiotic factors play a role in recycling nitrogen ( A )
- Farming practices and chemicals lead to a build-up of nitrates in the soil ( E )
Nitrogen cycle is biochemical process whereby nitrogen is converted to various chemical forms as it passes through the atmosphere, Marine and terrestrial ecosystems .
Nitrogen cycle undergoes four ( 4 ) important processes which are :
- Fixation
- Ammonification
- Nitrification and
- Denitrification
Hence we can conclude that The statements that describe steps taking place in the nitrogen cycle are :
Many biotic and abiotic factors play a role in recycling nitrogen and
Farming practices and chemicals lead to a build-up of nitrates in the soil
