When you breathe, the pressure inside the lungs is different than the pressure outside the lungs. This is an example of a(n) __________. When you breathe, the pressure inside the lungs is different than the pressure outside the lungs. This is an example of a(n) __________. concentration gradient pressure gradient electrical gradient temperature gradient
Answer:
pressure gradient
Explanation:
The correct answer would be pressure gradient.
A pressure gradient is created when there is a difference in the amount of pressure between two points or locations that are adjacent to one another.
In this case, the two locations that are adjacent to one another are the inside and outside of the lung. When one breathes in, the pressure inside the lung is more than that of the outside and the lung expands as a result. When we breathe out, the pressure outside is more than that of the inside and the lung collapses.

which type of hormone diffuses across the plasma membrane and binds to receptors in the cytoplasm module 16.4c
Answer:
Steroid hormones.
Explanation:
Steroid hormones is a type of hormones that diffuses across the plasma membrane and binds to the receptors present in the cytoplasm. The hormones are released from the carrier protein and diffuse inside the cell across the lipid bilayer of the plasma membrane of the cells. The steroid hormones pass through the plasma membrane of a target cell and attached to the intracellular receptors located in the cytoplasm or in the nucleus.
Explain the properties of proteins and its general structure
Answer:
The common property of all proteins is that they consist of long chains of α-amino (alpha amino) acids. The general structure of α-amino acids is shown in . The α-amino acids are so called because the α-carbon atom in the molecule carries an amino group (―NH2); the α-carbon atom also carries a carboxyl group (―COOH).

Describe the change in shape of the lens when a person looks from a near object to a distant object
Answer:
Accommodation is the process of changing the shape of the lens to focus on near or distant objects.
To focus on a near object – the lens becomes thicker, this allows the light rays to refract (bend) more strongly.
To focus on a distant object – the lens is pulled thin, this allows the light rays to refract slightly.
What movement of the thumb would be most affected by lesion of the median nerve in the cubital fossa
Answer:
flexion
Explanation:
The flexion is a movement of the body part that is described the bending of an elbow, or the clenching a hand into a fist, etc. where the angle between any segment of the body and its proximal segment decreases.
In simple words, the flexion is a movement which decreases the angle between two body parts when they are moved.
The flexion occurs in the sagittal plane.
Thus, the movement of a thumb that would be mostly affected by the lesion of median nerve in cubital fossa is the flexion movement.

Why do biologists classify
Answer:
Biologists classify organisms because:
Classification allows us to understand diversity better. It helps in the identification of living organisms as well as in understanding the diversity of living organisms. Classification helps us to learn about different kinds of plants and animals, their features, similarities and differences. It enables us to understand how complex organisms develop from simpler organisms. They are grouped under different categories to understand and study the features, similarities and differences between different living organisms. It is essential to understand the inter-relationships among the different groups of organisms. Classification forms a base for the development of other biological sciences.Why the water is an inorganic, transparent, tasteless, odorless, and nearly colorless chemical substance?
Answer:
Water is inorganic, transparent, delicate, odourless, and almost colourless.
Explanation:
How colourless is the water?
In fact, it isn't. It's weakly blue, and when many of them are gathered together, it gets obvious. However, it's obviously not very colourful. This is a pretty common occurrence. Very few simple materials are coloured intensely. Pure salt and sugar are also colourless and clear. They look white in mass because the little crystals disperse light, but the snow does the same. A fluid forms a uniform bulk.
Substances are seldom pure in nature, of course. Not so much looks colourless, therefore. It takes just a few colourful uncleanness to colour the whole thing. Look for Himalayan salt or sugar or orange juice unprocessed.
Why is water odourless?
We don't have to taste it because of this. From that feeling, we obtain a decent estimate of the water content of food. The oils, which feel much different, usually are other liquids. Moreover, the exact amount of water in a certain food item is not all so important, if we need moisture we will certainly drink things that are primarily water.
The sensation of taste without water releases the ability to discern other things.
Why does water smell?
We don't have to smell it, too. There is no genuine advantage of being able to identify the humidity of the air instantaneously. It's better to use the sense of smell to detect poisons, nutrients, relatives or strangers, etc. IN various ways, we can tell how the weather is.

question
OW
OX
OY
OZ
Answer:
Z
Explanation:
The first stage of cellular respiration is called GLYCOLYSIS, where glucose is broken down into pyruvate. Because glycolysis occurs irrespective of whether there is oxygen or not, it occurs in all organisms. Hence, glycolysis occurs in the CYTOPLASM of their cell.
In this question, a diagram was given as an attachment. In the diagram, letters W, X, Y amd Z are used to represent organelles in the cell. Letter Z represents the cytoplasm, hence, the first stage of cellular respiration takes place in Z.

Until DNA evidence provided evidence to the contrary, flagellated spores were used to group the blastocladiomycetes with the ____.
Answer:
Chytridiomycetes
Explanation:
Blastocladiomycetes were initially grouped under the phylum Chytridiomycetes within the fungi kingdom because the former also have flagellated spores just like the latter
The similarity in spores initially made scientists classify both groups as zoosporic fungi. However, DNA and structural analysis of the spores of the two groups showed that Blastocladiomycetes has no monophyletic relationship with Chytridiomycetes.

From deep to superficial, the order of the strata of the epidermis is corneum - granulosum - lucidum - spinosum - basale. spinosum - granulosum - basale - lucidum - corneum. basale - granulosum - spinosum - lucidum - corneum. corneum - lucidum - granulosum - spinosum - basale. basale - spinosum - granulosum - lucidum - corneum.
Answer:
basale - spinosum - granulosum - lucidum - corneum.
Explanation:
The order of strata in the epidermis:
Basale: it is the deepest stratum. It has one layer of cells called keratinocytes, which are stem cells for the epidermis.Spinosum: The keratinocytes in this layer have spiny shapes. They synthesize cytokeratin and lipids. In this layer, we can also find macrophages.Granulosum: The keratinocytes of the previous layer ascend and synthesize keratohyalin, which is in granules. The keratohyalin helps to join keratin filaments. Also, the cells release the lipids synthesized in the previous layer, and they form a barrier that stops dehydration.Lucidum: it is only on thick skin, like the one in the sole of the feet. The keratinocytes in this layer have expelled the nucleus and now are dead cells. The keratinocytes have a flat shape and form a thin layer.Corneum: it is the most superficial layer. It is made of dead keratinocytes filled with keratin in their cytoplasm. It is a thick layer that suffers desquamation when new dead cells filled with keratin ascend from the previous layer.The perimeter of a rectangle is 16 inches.

Hantavirus is a relatively rare emerging infectious disease that is spread by contact with the contaminated feces and urine of rodents, such as deer mice. It does not spread between people and causes flu-like symptoms. How would scientists most likely recommend that the disease be controlled?
Answer:
They would instead focus on controlling and diminishing the rodent population.
Explanation:
They would instead focus on controlling and diminishing the rodent population. The best solutions are always those that target the cause of the problem. Therefore, since the cause of the virus are rodents and that is how the virus spreads, then targetting the rodent population would be the best choice. The scientists would have to figure out a way of keeping track and controlling where the rodent population moves, as well as figuring out how to control their reproduction and diminish their population size. All of this while also trying to predict the possible effects that the population size can have on the environment.
