Cecil is sexually attracted to his middle-school English teacher. He doesn’t act on his feelings however, because he realizes th

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.

A blue-eyed, left-handed woman marries a brown-eyed, right-handed man who is heterozygous for both of his traits. if blue eyes a

Pavel [41]

4 different phenotypes may be produced. If you write this down in a Punnet square you can get the exact ratio and the genotypes along with the phenotypes.

Let us assign B for brown eyes, b for blue eyes; H for right-handed, h for left-handed.
The mother's genotype will then be bbhh
The father's genotype will then be BbHh

bh bh bh bh
BH BbHh   BbHh BbHh   BbHh
Bh Bbhh Bbhh    Bbhh   Bbhh
bH bbHh bbHh    bbHh   bbHh
bh bbhh bbhh bbhh bbhh

Now based on that you can see that there are 4 possible genotypic combinations which would express different phenotypic combinations as well.

BbHh: Brown-eyed, right-handed
Bbhh: Brown-eyed, left-handed
bbHh: Blue-eyed, right handed
bbhh: Blue-eyed, left-handed

So again, there would be 4 possible phenotypes.

A denisty of a bottle weighs 0.25N when empty & 0.75N when filled with water & 0.65N when filled with alcohol. Calculate

Ulleksa [173]

Answer:

$0.05\times 10^{-3}\ \text{m}^3$

$800\ \text{kg/m}^3$

Explanation:

$W_b$ = Weight of bottle = 0.25 N

$W_w$ = Weight of water = $0.75-0.25=0.5\ \text{N}$

g = Acceleration due to gravity = $10\ \text{m/s}^2$

$\rho_w$ = Density of water = $1000\ \text{kg/m}^3$

Mass of water

$m_w=\dfrac{W_w}{g}\\\Rightarrow m_w=\dfrac{0.5}{10}\\\Rightarrow m_w=0.05\ \text{kg}$

Volume is given by

$V_w=\dfrac{m_w}{\rho_w}\\\Rightarrow V_w=\dfrac{0.05}{1000}\\\Rightarrow V_w=0.05\times 10^{-3}\ \text{m}^3$

Volume of the bottle is $0.05\times 10^{-3}\ \text{m}^3$ .

This means that the alcohol will take the same amount of volume.

$W_a$ = Weight of alcohol = $0.65-0.25=0.4\ \text{N}$

Mass of alcohol

$m_a=\dfrac{0.4}{10}\\\Rightarrow m_a=0.04\ \text{kg}$

Density is given by

$\rho=\dfrac{m_a}{V_w}\\\Rightarrow \rho=\dfrac{0.04}{0.05\times 10^{-3}}\\\Rightarrow \rho=800\ \text{kg/m}^3$

Density of alcohol is $800\ \text{kg/m}^3$

A viewing of the behavior of groups in a systematic way.

dlinn [17]

<span>Viewing of the behavior of groups in a systematic way is known as sociological perspective.

Sociology views provide us with different perspectives which helps us to view social world. Sociology has three major theoretical perspectives which include functionalist perspective, symbolic interactionist perspective, and conflict perspective.

Different perspectives offer a variety of explanations on human behavior and social world.</span>
