How did animals change to mimic others? this genuinely fascinates me and I want to know how they do it- like- the Viceroy Butterfly mimics the poisonous Monarch Butterfly. but- h o w - did they spend so much time watching the Monarch that they slowly became their look-alikes? how does mimicry happen over time....

Answers

my understanding is that they evolve over time, one could say adapt, to survive to mimic other creatures, im sure there are plenty of books you could borrow from a library or buy online to learn more, and there are different studies people have done you might be able to find free online!!!

Answer:

They evolve over time

Explanation:

Animals evolve over time to fit into their surroundings and to survive. This could take several generations though, because change doesn't happen over night. To put it simply, survival of the fittest. They have to fit in in order to survive, so they did exactly that.

Think of a time when you were extremely scared or nervous and experienced an adrenaline rush. Write about your experience below.

One day I was walking down a river with my friends. After a while of walking a 3 feet snake jumped out of the river and scared the living out of us. The snake left but the adrenaline rush made me jump onto a tree without planning to jump on the tree.

Once when I was 9 my friends and I were walking by a pond when we got a bad vibe so we left. While we were walking we spotted a ditch and decided to go and check it out. So when we were there we kept hearing wierd noises but thought it was just some birds or something. (Keep in mind there was a sorta tunnel that went under the road that lead from the ditch to the pond.) So my friend said he saw something in the tunnel and when we looked in the tunnel there was someone there looking back at us so we of the ditch and went to the playground nearby. We haven't gone back since, lol.

Plant cells use photosynthesis to make the organic compounds that their mitochondria and other organelles need. Where do you think animal cells get these same organic compounds from? How do their cells use these compounds?

Answers

The animals cells get their compounds by eating

The organelles called mitochondria in cells are capable of generating energy. Plants need mitochondria to make ATP from different chemical sources, even though they derive their energy from the Sun.

What organic compound synthesize in animal cell for energy?

Cellular respiration, a process that releases energy by mixing glucose and oxygen, is the method that all cells rely on to obtain their energy.

The process of releasing energy from meals takes place inside the body's cells during respiration.

As part of the respiration process, the body's cells absorb oxygen from the air, use it to produce energy by burning food, and then expel the waste materials (carbon dioxide and water) from the body.

Plants use the carbon dioxide exhaled during respiration for the process of photosynthesis. Animals do not use the carbon dioxide produced during breathing; instead, it is expelled outside the body.

Therefore, animal cells get these same organic compounds from cellular respiration.

How did migration lead to the population of the world?

Answers

The more people that came to a certain place gained its population, while the people that left decreased the population .

Climate Change Some of the biggest human migrations coincided with major changes in climate, according to a new analysis. Researchers say early humans set out in search of climates where more food was available. And some populations stayed put in certain locations because barriers like glaciers blocked their progress.

What are the benefits of living in a permanent settlement vs. a nomadic settlement? Include at least three benefits.

Answers

Answer:

One of the most obvious advantages is being able to grow and harvest crops on land as a result of agriculture, rather than relying on natural landscapes to provide. Another is safety and security — you do not have to traverse potentially dangerous routes and can defend your land from your home. Finally, urban cultural centres are not possible when moving from place to place as you have to take everything with you. Permanent settlement allows advanced civilisations to develop.

EASY HELP! WILL MARK BRAINLIEST! Humans role and impact in ecosystem?

Answers

Human impact on the environment includes changes to biophysical environments and ecosystems, biodiversity, and natural resources caused directly or indirectly by humans, including global warming, environmental degradation (such as ocean acidification), mass extinction etc.

Good Impact:

1. Humans garden, grow trees and plants. We also breathe out carbon dioxide, which “feeds” the trees. We impact the ecosystem by making it healthier by doing these things.

Bad Impact:

2. Humans sometimes litter and throw trash on the ground then it can make its way into the ocean. Due to this, the oceans that used to be beautiful are now full of trash and sea animals are swallowing and eating the plastic that we throw in. Making them die. Also this can kill the coral reefs which protects coastlines from damaging effects of wave action and tropical storms.

In science class, your teacher opens a perfume bottle to model cell transport. She asks the students to identify the type of cell transport and to explain the method of movement. Which of the following is the best explanation for this model? *

A.) This model demonstrates osmosis, because the perfume molecules are moving from an area of high concentration to low concentration.
B.) This model demonstrates osmosis, because the perfume molecules are moving from an area of low concentration to high concentration.
C.) This model demonstrates diffusion, because the perfume molecules are moving from an area of high concentration to low concentration.
D.) This model demonstrates diffusion, because the perfume molecules are moving from an area of low concentration to high concentration.

Answers

C. The perfume molecules are diffusing around the room. As these molecules drift from each other they begin to diffuse around other gases like oxygen. This is why when you spray a perfume right in front of you it’s too concentrated (or too much) to breathe in but once the perfume is able to diffuse and spread out it is able to be smelled without hurting your nose!

it’s diffusion. diffusion goes from an area of high concentration to an area of low concentration. so the answer is c.

BRAINLIEST Can a ocean wave freeze and i give brainliest and i want friends

Answers

Ocean water freezes just like freshwater, but at lower temperatures. Fresh water freezes at 32 degrees Fahrenheit but seawater freezes at about 28.4 degrees Fahrenheit, because of the salt in it. When seawater freezes, however, the ice contains very little salt because only the water part freezes. It can be melted down to use as drinking water.

Answer:

A wave can freeze, but it would need a lower, more intense cold to freeze it. This is because it has little salt. And for 2, sure? I don't know?

In a step by step format, write about the process of the blood flow as it enters the heart until it leaves the heart. It should be at least 150 words.

Answers

First, unoxygenated blood enters the right atrium from the superior and inferior vanae cavae. Next the blood flows through the tricuspid valve into the right ventricle. From the right ventricle, the blood flows through the pulmonic valve into the pulmonary artery. The right and left pulmonary arteries then carry the unoxygenated blood to the right and left lungs for oxygen. The blood picks up a fresh supply of oxygen & releases carbon dioxide as waste. The now oxygenated blood flows through the pulmonary veins from the lungs into the left atrium. From the left atrium the blood flows through that bicuspid or mitral valve into the left ventricle. The left ventricle contracts, thus forcing blood through the aortic valve into the aorta for the distribution to the systemic circulation

Can any kind soul help me ASAP The Story of Cam and Tam Kyle Ellington 1Once upon a time, a widowed man lived in a small kingdom and cared for his kind daughter, Tam, by himself. Eventually, the man remarried, but his new wife was cruel to Tam. Tams life worsened when a baby girl, Cam, was born. Tams father and stepmother showered Cam with everything she desired, leaving Tam to live a desolate, lonely life. She cleaned the house, cooked the food, hauled the trash, and collected the water. 2One day, Tams stepmother sent her and Cam to collect fish. Though they were half sisters, Tam and Cam had contrasting personalities. Tam fished continuously until her basket overflowed with fish, while Cam lazily lounged in the sun. Upon realizing that she had no fish to take home, Cam decided to steal Tams fish. When Tam wasnt looking, Cam poured Tams fish into her own basket, snickered, and fled home. 3Tam wept when she saw the empty basket because she knew that punishment awaited her; however, she stopped crying abruptly when a beautiful woman appeared. The woman grinned sweetly and told Tam not to weep. 4Your misfortunes will be over soon, Tam. Inside your basket, you will find one fish. Take it home and care for it, said the woman. 5Tam put the fish in the well behind her house. Each time Tam neared the well, the fish surfaced, which made Tam very happy. One day, because Tam's stepmother despised Tams happiness, she removed the fish from the well and returned it to the river. The next time Tam visited the well, the fish did not surface. Tam instantly knew what had occurred and wept. Once again, the beautiful woman appeared. She instructed Tam to visit the fish at the edge of the river whenever she needed help. 6A few weeks later, the Autumn Festival began, and Tams town erupted with activity. Tam planned to attend the festival, but her stepmother wrote a list of many chores for her to complete. Saddened, Tam visited the water's edge and asked for help. In a moment, the beautiful woman appeared before Tam and instantly transformed Tam's shabby clothes into a stunning blue and silver dress. 7Tam raced to festival, where she earned praise as the most beautiful woman in attendance. Tam shimmered like a star in the glowing gown, but having everyone's eyes on her made her self-conscious, and she ran away. In her haste, she lost a shoe on the staircase. 8Later, the Prince discovered Tams lost shoe. He had seen Tam at the festival and hoped to marry her. He traveled the kingdom seeking the woman whose foot fit the shoe. When the Prince arrived at Tams house, she tried on the shoe and it fit! The Prince was jubilant and asked Tam to marry him. Eventually, the Prince became King, and Tam became Queen. Though Tam never took revenge on her family members, they lived in agony knowing that if they had been kinder, they could have lived with Tam and the King.A) by creating sympathy for the abused and oppressed character, TamB) by characterizing one of the two young women as wicked and cruelC) by utilizing a natural creature, a fish, as a friend to poor, lonely, TamD) by having the beautiful woman appear several times to help Tam as her life worsens What value of x makes this equation true X/6-7=4 What is the domain of this function?
