The plague nearly destroyed Italy's economy.
Renaissance women had less freedom than men.
The effects of the Renaissance are still felt today.
Renaissance Italy was the center of trade as well as culture.
Both arts and sciences flourished during the Renaissance.
Italy prospered when it began selling different products,
Possible Supporting Details
"Gradually, Italy began to specialize in luxuries such as artistic metalwork,
fine leather, and beautiful furniture."
"By the end of the fifteenth century, the Renaissance had spread to Germany."
"Before long, scholars were rediscovering Greek and Roman art, science, and literature."
"Cities shrank, production slowed, and prices dropped."
"The press revolutionized education and standardized language."
"If you have women in your house, keep them shut up...."
Renaissance women had less freedom than men ↔ Low class women were expected to be housewives and take care of everything to do with the house. Working-class women were expected to help their husbands run their business. They were denied all political rights and considered legally subject to their husbands.
The plague nearly destroyed Italy's economy ↔ It became harder and harder to find people to plow fields, harvest crops, and produce other goods because of the amount of people dying. Peasants also began to demand higher wages. Lasted from 1629 to 1631 and killed more than 45,000 people in Venice alone. It wiped out over half the population.

What conditions are necessary for rocks to melt? ( I’ll give a Brainliast) please answer
Answer:
The rock is pulled down by movements in the earth's crust and gets hotter and hotter as it goes deeper. It takes temperatures between 600 and 1,300 degrees Celsius (1,100 and 2,400 degrees Fahrenheit) to melt a rock, turning it into a substance called magma (molten rock).
Answer:
Flux melting occurs when water or carbon dioxide is added to rock. These compounds cause the rock to melt at lower temperatures. This creates magma in places where it originally maintained a solid structure. Much like heat transfer, flux melting also occurs around subduction zones.

If a plant is releasing carbon dioxide and taking in oxygen during the day, does it mean that there is no photosynthesis occurring? Justify your answer.
➜ Release of CO2 and intake of O2 gives evidence that either photosynthesis is not taking place or its rate is too low. Normally during day time, the rate of photosynthesis is much more than the rate of respiration. So, CO2 produced during respiration is used up for photosynthesis hence CO2 is not released.

What needs to happen first for fertilization to take place? The ovary releases an egg into the uterus. Sperm travels to the Fallopian tube. The protective covering of the egg hardens.
Answer:
To become pregnant, the following steps must occur: Sperm transport — The sperm must be deposited and transported to the site of fertilization. Egg transport — Ovulation must occur and the egg must be "picked up" by the tube. Fertilization and embryo development — Union between the sperm and egg must result.

How many codons equals 1 amino acid?
Answer:
Explanation: The nucleotide triplet that encodes an amino acid is called a codon. Each group of three nucleotides encodes one amino acid. Since there are 64 combinations of 4 nucleotides taken three at a time and only 20 amino acids, the code is degenerate (more than one codon per amino acid, in most cases)
if the checkpoint finds an error, what are some actions the cell can take to ensure the error does not get replicated?
Answer:
If the checkpoint mechanisms detect problems with the DNA, the cell cycle is halted, and the cell attempts to either complete DNA replication or repair the damaged DNA. If the damage is irreparable, the cell may undergo apoptosis, or programmed cell death 2.
Explanation:
um i think this is correct. hope this helps and have a nice day
-KindnessMatters-
The cell cycle is the intricate process of replication of genetic material and producing the daughter cells. The cell cycle is regulated by several mechanisms, one of which is checkpoints.
Checkpoints are the sites where the cells are checked for errors and inaccuracy in the cell.
The cell takes action to ensure errors are not replicated as:
The G1 checkpoint in the cell cycle is the primary checkpoint, which decided whether the cell should divide or not divide. It checks for size, DNA damage, and nutrients. The cell cycle will halt if there will be any errors. The G2 checkpoint is involved in the overall smoothening of the cell cycle. If any damage is observed after the other checkpoints, the cell cycle will pause in the G2 phase, halting the replication of errored genetic material.The M checkpoint corresponds to accurate attachment of the sister chromatids and the cycle will be in pause if the proper attachment is not done.
Thus, there are several checkpoints to check the errors in the DNA, and if any error persists, the cell cycle will be halted.

Two objects are placed a certain distance from each other. The amount of gravitational force between the two objects depends on
their masses and the distance between them.
As the masses of the objects decrease, the force of gravity between them
As the distance between the objects
decreases, the force of gravity between them
OA. increases, increases
OB. decreases, increases
OC. decreases, decreases
OD
increases, decreases
Answer:
OB. decreases, increases
Explanation:
The formula is F = GM1M2/r^2. so you can see the gravitational force is directly proportional to the masses and inversely proportional to the distance.
Answer:
The answer is B. decreases, increases.
when is it possible to break even in an energy transformation?
a. always
b. late phase
c. early phase
d. never
please help!!
Answer:
I beleive always.
Explanation:
sorry if wrong
It cannot be possible to break even in an energy transformation. Thus, option D is correct.
what is energy transformation?
The primary forms of energy are light, mechanical, chemical, nuclear, electrical, heat, and sound.
Energy only convert from one form to another is known as energy transformation or conversion.
The Sun is the primary source of energy that is nuclear energy changed into electromagnetic energy like light energy.
This light energy travels in the form of waves reach the earth surface taken up by plants for doing photosynthesis.
Now light energy is converted into chemical energy which can be used up by animal and human in their food.
The chemical energy of the food converted into heat and mechanical energy which maintain the body’s temperature and involve in various physiological process like motion, breathing, standing, or running.
