Answer:
D. physiological mechanisms are the basis of behaviors.
Explanation:
The example of the development of electric fields as part of the communication between some fish, shows the interrelation that exists between physiology and behavior. This physiological factor that fish have has an impact on their behavior. However, it is necessary to recognize that physiology does not act by itself, but needs to receive a stimulus from the surrounding environment.
This way of communicating is called electrocommunication, a fish generates through its physiology an electric field and a second individual receives that electric field with its electroreceptors.
All I know is that stem cells are made in the bone marrow, and they differentiate into red blood cells
the formula to find force is F=ma
F- Force (in newtons)
m- mass (in kg)
a- acceleration (in m/s)
in this case you need to find acceleration, so isolate a by making the formula a=f/m. plug in your numbers then you're done
a=30/70
a=0.429 (rounded)
Answer:
the last answer
Explanation:
over time by co-evolution of adaptations that reduce the harm or improve the benefit of the relationship
Organic matter is added to basic soil to neutralize its base which improves its quality.
<h3>What is an organic matter for soil? </h3>
Manures are organic matter. These are the waste products of plants and animals that are used as sources of plant nutrients. After their decomposition, they release nutrients.
The practice of collecting and using wastes from animal, human and vegetable sources for the improvement of productivity of crops is as old as the practice of agriculture.
Plant nutrients in complex organic forms are present in the manure which is the organic matter in the plant and animal wastes. The synthetic chemicals that contain plant nutrients are called fertilizers.
Manures have low nutrient content per unit quantity and have a longer residual effects. They can work by improving soil's physical properties compared to fertilizer with high nutrient content.
Therefore, organic matter is added to basic soil to neutralize its base which improves its quality.
