Answer:

Independent: Purposely altered

Dependent: Changes with respect to the independent being altered

Controlled: Never changes

Explanation:

An independent variable is a variable in which does not rely on other pieces/variables of an experiment to assume a value. In other words, it does not change when other variables change. However, it can be changed intentionally by the scientist.

A dependent variable is a variable in which its change in value relies on other pieces/variables of an experiment to assume a value. So, if the indeoendent variable is changed, the dependent variable will change as well. The opposite is not true though - if the dependent variable changes (for whatever reason), the independent variable hasn't necessarily been changed.

A controlled variable is a variable that stays CONSTANT throughout an experiment. It is never changed, and nothing will change it. An example of a control variable is the number of participants in a study: no more participants are being added, and no participants are being removed. The number of participants remains STATIC throughout the study.

Alex777 [14]

Answer:

Ego

Explanation:

In 1923, Sigmund Freud's personality theory was structured into three different parts viz: Id, ego and superego

The id is the instinctive and unconscious part of the personality which responds directly to urges, needs and desires. The id operates on the pleasure principle that every wishful impulse should be satiated instantly regardless of the resulting effect.

The ego is the part that mediates between the unreasonable id and societal beliefs. It is the reasoning and decision-making component of the psyche.

The superego is the part that acts as a self critical conscience, reflecting the social standards that has been learnt

In this scenario involving Cecil, the id part of his personality is responsible for the sexual attraction to his English teacher but the ego part of his personality is making him realize that is socially unreasonable for his teacher to respond to his sexual advances. His ego, which operates with the reality principle is restraining him from acting from his feelings in consideration of social realities.

Therefore, his ego is restraining him from expressing his feelings of sexual attraction (Id) considering societal consequences.

_____ is the main provider of energy for the brain and nervous system.
defon
Glucose is the main provider of energy for the brain and the nervous system. Because the brain is so rich in nerve cells, or neurons, it is the most energy demanding organ, using one half of all the sugar energy in the body. Brain functions such as memory, thinking and learning are closely linked to glucose levels and how efficiently the brain uses this fuel source.

Write a scientific explanation that explains how oxygen and carbon dioxide travel within the seed and the egg.
svet-max [94.6K]
The two membranes pull apart a little and create a small pocket or sack of air. As the developing bird grows, it breathes in oxygen from the air sack and exhales carbon dioxide. Several thousand microscopic pores all over the surface of the egg allow the CO2 to escape and fresh air to get in.
