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

Answers

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.

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.

How are ciliated epithelial cells adapted to their function?

Super urgent best answer gets brainliest

Answers

Answer:

Ciliated cells are adapted in the respiratory tract to form an epithelial lining of coordinated metachronal ciliary activity that provides the propelling force for the transport of mucus along the airways.

HOPE IT HELPS !!

ciliated (meaning, they have cilia) epithelium (lining tissue) found in the lung facilitates the removal of foreign particles and debris from the lung. These cilia beat in a coordinated fashion to move molecules from the lower respiratory tract up to the trachea. Ciliated cells are adapted in the respiratory tract to form an epithelial lining of coordinated metachronal ciliary activity that provides the propelling force for the transport of mucus along the airways. This mechanism is central to the maintenance of patent airways and pulmonary homeostasis.
Cilia are tiny hair like structures on the surface of the cell. ... The hairs sweep hair, mucus, trapped dust and bacteria up to the back of the throat where it can be swallowed. Ciliated columnar epithelium is composed of simple columnar epithelial cells with cilia on their apical surfaces. These epithelial cells are found in the lining of the fallopian tubes and parts of the respiratory system, where the beating of the cilia helps remove particulate matter. It is covered with epithelial cells that protect your body by being a barrier between your internal cells and the dirt and microbes in the environment. They also are able to stretch so you can move your fingers and arms into many positions.

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.

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.

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

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.

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.
