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?

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.

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.

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
