Describe what happens to the air in the lungs when we breathe. What happens to the concentration of
carbon dioxide and to the concentration of oxygen?
When we breathe in, oxygen enters our lungs and enters small sacs in our lungs called the alveoli. In the alveoli, the oxygen diffuses INTO the bloodstream through small blood vessels, called capillaries, that surround these alveoli. The oxygen is now in our bloodstream instead of our lungs and is used in cell respiration etc.
Oppositely, carbon dioxide is diffused FROM the bloodstream TO the alveoli, also through these capillaries. The carbon dioxide is now in the lungs instead of the bloodstream and when you breathe out, the carbon dioxide is breathed out out of your lungs.
Hope this helped, even if it helped a tiny bit. :)

What is the difference between osmosis & diffusion?
What are the TWO types of active transport?
What are the TWO types of passive transport?
Substances can only move into or out of a cell if the cell membrane is ___________________.
Explanation:
osmosis is the movement of solvent particles across a semipermeable membrane diffuison is the movement of particles from area of higher concentration to lower concention
primary active transport and secondary active transport
diffusion or water carbon dioxide
In diffusion, particles move from an area of higher concentration to one of lower concentration until equilibrium is reached. In osmosis, a semipermeable membrane is present, so only the solvent molecules are free to move to equalize concentration.
2. What are the TWO ,types of active transport?There are two types of active transport: Primary active transport that uses adenosine triphosphate (ATP)and secondary Active transport that uses an electrochemical gradient.3. What are the TWO types of passive transport?
Simple Diffusion and osmosis are both forms of passive transport and require none of the cell's ATP energy.
4. Substances can only move into or out of a cell if the cell membrane is:
Active Transport.
Those proteins do much of the work in active transport. They are positioned to cross the membrane so one part is on the inside of the cell and one part is on the outside. Only when they cross the bilayer are they able to move molecules and ions in and out of the cell.

explain three ways in which red blood cells are adapted to their function
Answer:
Red blood cells are adapted to their function by:
1) They contain haemoglobin - a red protein that combines with oxygen. they have no nucleus so they can contain more haemoglobin.
2) They are small and flexible so that they can fit through narrow blood vessels.
3) They have a biconcave shape (flattened disc shape) to maximise their surface area for oxygen absorption.

In 1665, Robert Hooke published micrographia a book in which observations he made with a microscope cause him to coin the term “cell”. He may have coined the term when he viewed a piece of dead cork, a type of plant, and thought it resembled the cells of honeycomb. If he had viewed a section of living cork, what might he have seen
Cork cells are packed closely together, the cells are generally arranged in radial rows.
What is a cell?
The fundamental units of all living things are cells. There are many billions of cells in a human body. They give the body structure, absorb nutrients from meals, turn those nutrients into energy, and perform certain tasks.
Cork cells are packed closely together, the cells are generally arranged in radial rows.
Separation among the cells is achieved by structures arising from the cork cambium called lenticels. These pore-like structures allow gases to be exchanged between the plant stem and the outside environment.

How do nucleic acids and carbohydrates interact?
Explanation:
When living beings eat, fats, carbohydrates, proteins, and nucleic acids are all absorbed. Protein-rich foods and their constituent amino acids are also rich in nucleic acids because cells in protein-rich foods have been actively involved in protein synthesis when the food was harvested. Tofu, soybeans, meat, poultry, fish, legumes (peas and beans), root vegetables, and dairy products are high-protein foods, which are also rich in nucleic acids.

Which phrase describes the best area to dig down to the groundwater?
A: where the saturated zone is 15 meters deep
B: where the water table is at 100 meters deep
C: where the unsaturated zone is 50 meters thick
D: where there is a 25-meter thick clay layer at the surface
Answer:
If the saturated zone is 15 meters deep, that area is the best to dig down so its A.
Explanation:
The saturated zone is the area under the ground where the water is stored in tiny spaces between rock, soil, sand, and gravel.
The water in this region flows freely through the pores within the geologic medium.
Most people dig a hole to insert pipes until this region identified with water for the purpose of boring and building wells.
These regions can be found after digging above hundred feet or just below the ground surface.
The phrase that describes the best area to dig down to the groundwater is where the saturated zone is 15 meters deep. The correct option is A.
What is groundwater?Water that is found in soil, rock, and rock formation fissures below the surface of the Earth is known as groundwater.
In the saturated zone, which is located below the surface, water is held in minuscule crevices between rocks, soil, sand, and gravel. In this area, the pores of the geologic media allow water to flow freely.
For the purpose of digging and building wells, most people dig a hole and place pipes into it until the area is filled with water. These areas can be reached by drilling a few feet or more below the surface of the ground.
Therefore, the correct option is A: where the saturated zone is 15 meters deep.

What is the your groundbreaking idea for a razor or hair removal product that awakens your senses?
Answer:
hope it helps you
Explanation:
Traditionally, shaving and hair removal brands provide mainly functional benefits: they get the job done, but they don’t deliver an enriching, self-care experience. Their products aren’t going to uplift you or make you feel calm and relaxed. Instead, they offer mundane experiences and boring designs and scents.
As a leading personal care brand, we are looking for razor and shave preparation ideas that will make shaving enjoyable, that are experiential, and that stimulate the senses (olfactory, tactile, vision, etc.). We are looking for creative solutions that will appeal to those who love variety, who enjoy exploring new things, and who value enriching experiences. Personal care should give us a chance to reground ourselves, awaken our senses, and feel better in our day-to-day.
We are interested in groundbreaking ideas for wet-shave devices (e.g. razors) and/or packaging that will awaken your senses without compromising the effectiveness or durability of the products.
Your idea could improve the sensory shaving experience at any level. Primarily, we are looking for ideas that relate to razors, but we are also open to shave preparation (pre, during, post shaving) as well as packaging. In proposing your idea(s), please consider the following:
Be creative! Feel free to go beyond scents / olfactory experience.
Bring ideas for razors, shave preparation, pre-shaving and post-shaving.
Women should be the target demographic for your product idea. Please be sure your idea has feminine appeal.
Your idea should be feasible for high-volume production (think about processing conditions and high speed manufacturing).
Your product idea should be able to survive in the typical “bathroom” / usage environment of a razor. Think of the shower, where there is high humidity, exposure to chemicals from other products, etc.
Please include any references or background information related to your proposed material sources. We want to understand what inspired your idea and review any relevant sources that support it!
Begin by answering the survey questions below.
Gifts on buying of products and scent in the products are the ideas that increases the sale of the product.
My groundbreaking idea for a razor or hair removal product is that the razor or hair removal product companies has to provide gifts on the buying of their products. This type of strategy will definitely increases the sales of their products.
The other groundbreaking idea is to make these products with a scent that refreshes the mind of the user. In this way the people will like the product and increase the sales of these products so we can conclude that gifts on buying and scent in the products are the ideas that increases the sale of the product.

Which word describes the difference between the highest and lowest points in an area?
elevation
landform
relief
topography
Answer:
relief
Explanation:
The difference in elevation between the highest and lowest parts of an area.
The elevation term is usually used to define how high a point is from the plane surface. It is used as a measure of the difference between two points.
-----------------------------------------------
When talking about relief, we refer to everything that is over the plane or the surface. The term refers to the different forms on the earth's surface that might reach different heights and shapes. When talking about topography, we refer to the discipline or technique that makes a detailed description of a surface. It describes the relief. The term landforms refer to abrupt and sharp land irregularities. Elevations, depresions, bankruptcies, roughness, among others. These are natural characteristics of the earth's surface. Finally, the term elevation refers to the highest part of something. It is used as a measure that reflects the angle formed over the horizontal plane. Geographically, it refers to a piece of land that is over the plane surface surrounding it.Among all these terms, the only one that best describes the difference between the highest and lowest points is elevation. The term is closely related to the altitude term.
For instance, when saying that the peak of Pico de Orizaba has an elevation of 5,636 meters, we refer to the difference existing from the sea level to Pico de Orizaba's highest point.
