How did the sexual division labor evolved?

Answers

Answer 1

Answer:

Based on the current theories and research on the sexual division of labor, four critical aspects of hunter‐gatherer socioecology led to the evolutionary origin of the SDL in humans: long‐term dependency on high‐cost offspring, optimal dietary mix of mutually exclusive foods, efficient foraging based on specialized skill, and  sex‐differentiated comparative advantage in tasks.

Answer 2

Answer:

Based on the current theories and research on the sexual division of labor, four critical aspects of hunter‐gatherer socioecological led to the evolutionary origin of the SDL in humans:

(1) Long‐term dependency on high‐cost offspring

(2) Optimal dietary mix of mutually exclusive foods

(3) Efficient foraging based on specialized skill

(4) Sex‐differentiated comparative advantage in tasks.

Explanation:

These combined conditions are rare in nonhuman vertebrates but common to currently-existing populations of human foragers, which gives rise to a potential factor for the evolutionary divergence of social behaviors.

Can someone help me write a (well written) apology letter to my mom on disrespect

A paragraph

Answers

Answer:

Here you go! Just make sure to stay out of trouble

Explanation:

Dear Mother,

I deeply apologize on disrespecting you. You shine so bright and I could never ask for anyone better to be around. I apologize for all the times I've pestered you. You are the sunlight to my life, and I apreciate you. For now on if you ask me to wash the dishes I will get up and wash them. Reguardless of what I think. I will do my best to fullfill your expectations and hope to make you smile. I love you. Once again I apologize for all I have done. I will use this as an experience to learn from my mistakes, and be the best person I can be.

Love,

Your (Son or Daughter)

Handwrite this apology letter carefully; don't type it on a computer.

Express your apology in the beginning of your letter:

“I am so sorry...” or “I want to apologize...”

State exactly what you did wrong early in the apology letter:

“I shouldn't have lost my temper when...” or “I have looked all over, but I'm afraid I have lost your book...”

Accept responsibility for what you did and don't blame the other person:

“I accept full responsibility for what happened...” or “I know this was completely my fault...”

Promise in your apology letter not to repeat your offensive action

Ask the injured party to give you an opportunity to prove this to them.

Suggest that the two of you get together

Meet at a restaurant or some other nonthreatening place so that you can apologize in person and begin to rebuild your relationship.

I understand it's not a letter but I don't know what your mother is like. I hope this helps and hopefully, she forgives you. Leave a brainliest if this helps.

Elizabeth shivered as the wind howled outside the unfamiliar cabin. She hovered at the tiny window, anxiously searching for a glimpse
of her father. The twilight was fading fast; if Father did not hurry he would be trying to find his way back to their isolated new home in the dark
Earlier in the day. Elizabeth had unpacked their few belongings. Ashlight fell, something banged against the side of the cabin, rattling the dishes stacked by the empty fireplace, and Elizabeth jumped.
Which sentence should be deleted to improve the overall organization of the scene? Why? How could this sentence be revised to fit into the
existing organization of the scene?

Answers

The sentence "if Father did not hurry he would be trying to find his way back to their..." may be deleted to improve the overall organization of the scene.

We can arrive at this answer because

The text refers to a moment of tension in which Elizabeth finds herself, showing how the environment is affecting her.In that case, the sentence about Elizabeth's father can be excluded, as the text focuses on the suspense surrounding her.This would make the text more direct and objective.

This sentence can be revised to show how she worried and was afraid of her father's absence.

It indicates that the individual who was harmed was the same person who was rolling down the hill in the first place by reflecting the action back to the sentence's subject. The statement would be unclear without the reflexive pronoun "myself" and it would not communicate the intended meaning.

Which technique does propaganda primarily use?
ethos
pathos
logos
davros

Answers

Among the options, the rhetorical device or technique primarily used by propaganda is:

B. Pathos

The three rhetorical devices as explained by Aristotle are ethos, logos, and pathos.

Ethos appeals to the speaker's authority, logos to logic or reason, and pathos to emotion.

The purpose of those devices is the convince the audience of something.

Propaganda relies primarily on pathos. It tries to evoke an emotion from the audience to convince them to do something.

Secondly, it will use ethos, appealing to authority, to what an expert says.

The last choice will be logos, and it is only used when it supports the other devices.

Think, for example, of war propaganda trying to convince people to go to war. War is not reasonable. Asking someone to die is also quite foolish.

In order to convince someone to do it, propaganda would evoke feelings of rage against the enemy, of love and protection towards one's family, etc.

With that in mind, we can choose letter B as the best option.
