Answer:
Polyphyletic relationships .
Explanation:
The primary goal of modern systematics is construct 'family trees' that exhibit polyphyletic relationships because systemics deals with grouping or organising living organisms into groups base on biological meanings of function and polyphyletic relationships which is organising or grouping of organisms that don't have common ancestors Into different groups or unrelated organisms.
Answer:
EXERCISE
Explanation:
In an experiment, the independent variable is the variable that the experimenter changes or manipulates in order to bring about a measurable outcome.
In this case, an experiment is carried out to test the hypothesis that "exercise will affect the number of times a person can squeeze a clothespin in a certain amount of time". The experiment contained two groups (one group sits quietly before squeezing a clothespin as many times as possible and the other does 25 JUMPING JACKS before squeezing a clothespin as many times as possible).
The independent variable is the EXERCISE (jumping jacks) that was changed for each group in the experiment.
Xh is the recessive trait found in the female chromosome.
They have scales instead of skin or fur, as well as some being able to swim in water and walk on land. Many are poisonous and have several different tactics for catching prey from insects to small creatures like birds or mice. The Komodo dragon is a large reptile that has poisonous saliva which it uses to stun its prey.
The energy transformations that occur in the given devices are as follows:
- Windmill - mechanical energy to electrical energy
- Flashlight - electrical energy to light energy
- Microwave - electrical energy to heat energy
- Firecracker - chemical energy to heat, light, and sound energy
- Bicycle - Chemical energy to mechanical energy
- Battery - chemical energy to electrical energy
<h3>What is energy transformation?</h3>
Energy transformation refers to the processes by which one form of energy is transformed into another form.
The law of conservation of energy guides the various energy transformations that occur in the universe.
The law of conservation of energy states that energy is neither created nor destroyed but can be transformed from one form to another.
The energy transformations that occur in the given device are as follows:
- Windmill - mechanical energy to electrical energy
- Flashlight - electrical energy to light energy
- Microwave - electrical energy to heat energy
- Firecracker - chemical energy to heat, light, and sound energy
- Bicycle - Chemical energy to mechanical energy
- Battery - chemical energy to electrical energy
In conclusion, energy transformations occur according to the law of conservation of energy.
