Answer: Experiment.
Explanation:
Suppose that we have two related variables, A (independent) and B (dependent)
We could design an experiment where we can manipulate the value of A at will, and we also can observe how the variable B changes.
This is called an experiment, where the objective is to see how the variable B is related to the variable A, and then try to make a model that explains this relationship.
Answer:
Heliotropism
Explanation:
it's a type of tropism which is when a plant moves to where the sun is at because something is blocking it from getting sunlight which is why it moves to the sun
The spread of roots around a plant is usually greater than the depth of the roots is a completely false statement. It totally depends on the type of plant in regards to the type of root it will have. Normally there are two kinds of roots and they are taproot and fibrous roots. In case of taproots the main root goes downwards and smaller roots branches out of it. In case of taproots, it is true that the spread of roots is smaller than the depth of the roots. In case of fibrous roots, the spread of roots is greater than that of the depth of the roots. A wig tree is an example of a plant having taproot. in the wig tree the root can go to a depth of around 120 meters.
Answer:
B. Predation removes slower antelope from the herd.
Explanation:
Natural selection is defined as the differential survival and reproduction of individuals due to differences in the physical characteristics.
A predator-prey relationship results in a very fast-slow dynamical system for rapid predator evolution.
Predation removes slower antelope from the herd and hinders passage of the slow trait to offsprings. The ones who are fast reproduce and give birth to other fast animals.
