Explanation:
Where does diffusion take place in the respiratory system?.
Answer:
the alveoli
Explanation:
Gas exchange occurs at the alveoli in the lungs and takes place by diffusion. The alveoli are surrounded by capillaries so oxygen and carbon dioxide diffuse between the air in the alveoli and the blood in the capillaries.
—-------------—---—————————————————-
As the blood moves through the capillaries in the alveoli, oxygen diffuses into it and carbon dioxide diffuses out of it
At the muscles, the opposite occurs as carbon dioxide enters the blood from the muscle while oxygen enters the muscle from the blood.
Capillaries surround the alveoli in the lungs. Both the capillaries and alveoli walls are very thin - just one cell thick. They are made of semi-permeable membranes which allow oxygen and carbon dioxide to pass through them.

Three students are arguing over the correct interpretation of the tree below. Student A insists that pine is the most highly evolved living species because it evolved most recently and is more complex than the other species. Student B says the amoeba is the most highly evolved living species because it is older than the other species. Student C says that no living species is more highly evolved than another because all living species have been evolving for the same amount of time from their common ancestor. Which student is correct
Student C is correct because evolution does not necessarily lead to adaptation. Adaptation is an evolutionary process.
Evolution and adaptationThe term 'evolution' can be defined as the general view of 'descendence with modification', which generally occurs due to natural selection.
Organisms evolve to adapt (adjust) to different challenging environmental conditions.
However, a challenging environment may represent normal conditions for another species.

A type of transport protein that is an open passageway for the facilitated diffusion of ions or molecules across a membrane.
Answer:
A gated channel protein is a transport protein that opens a "gate," allowing a molecule to pass through the membrane. Gated channels have a binding site that is specific for a given molecule or ion.
In stratified epithelium, the cells in the deepest layer are often a different shape than the cells in the most superficial layer. This tissue is classified according to the shape of the cells in the ______ layer
Stratified epithelium is classified according to the shape of the cells in the apical layer, that is the layer towards the surface.
How is the stratified epithelial tissue classified?Stratified epithelium refers to the tissue that consists of two or more layers of epithelial cells. The main purpose of this multilayer is to protect the underlying tissues. These are present in areas that are more prone to wear and tear.
Stratified epithelium is classified on the basis of type of cell at the apical layer and underneath layers of cells can be varying. The types of stratified epithelium are as follows:
1. Stratified squamous epithelium - the cells at the apical layer are squamous, that is flat-shaped. Involved mainly in protection.
2. Stratified cuboidal epithelium - the cells at the apical layer are like cubes or hexagons. Involved in secretion and absorption as well as protection.
3. Stratified columnar epithelium - the cells at the apical layer are tall like columns and have cilia or villi, specialized for secretion and absorption.
4. Transitional epithelium - these apical layer cells are able to change shape to cuboidal or columnar, located in structures that are capable of expanding and contracting.
Thus, the correct answer is apical layer.

What is the blood volume of an average sized adult.
what are the steps leading to a cell becoming cancerous
Answer:
Cancer is unchecked cell growth. Mutations in genes can cause cancer by accelerating cell division rates or inhibiting normal controls on the system, such as cell cycle arrest or programmed cell death. As a mass of cancerous cells grows, it can develop into a tumor.
Explanation:
The steps leading to a cell becoming cancerous are mutation, growth and tumor.

Just from the way the question is structured, you can tell that a question has already been asked. And you made a prediction already (thinking like a scientist you predict). You could only analyze the observations after you have tested the hypothesis, which hasn't been done.
These are models of a plant cell and an animal cell. How can you use the models to help you describe the cell parts that are different between plant and animal cells? Include how the differences in the structures contribute to the function of the whole animal cell and plant cell..
Answer:
Chloroplasts are what give plants their green color. The second major difference between plant and animal cells is the cell wall. While both plant and animal cells have a cell membrane, on plants have a cell wall.
Plants are a green tint because of chloroplasts. The cell wall is the second key distinction between animal and plant cells. Animal and plant cells both have a cell membrane, but only plants have a cell wall.
What is chloroplasts?Chloroplasts are organelles found in plant cells that use the photosynthetic process to transform light energy into relatively stable chemical energy. They help keep life on Earth going by doing this.
Photosynthesis, the process of converting light energy into sugar and other organic compounds utilized as nourishment by plants or algae, is their responsibility.
They also produce the lipid and amino acid components required for the synthesis of chloroplast membranes.
Chloroplasts, which house the chlorophyll in plants, are where photosynthesis occurs.
Therefore, chloroplasts describe the cell parts that are different between plant and animal cells.
