Explain how the structures in the gas exchange system cause inspiration.

Answers

Inspiration is a process in which the lungs receives air from the extrinsic environment.

The process of gas exchanges involves a number of organs and tissues in the body of certain organisms. However, respiratory muscles as part of the body, are used in gas exchange and chiefly used in inspiration.

Inspiration occurs as a result of muscles contraction (for instance, diaphragm and the external inter-coastal muscles) and thus, increasing the volume of the thoracic cavity, which leads to the decrease in the atmospheric pressure in the lungs to supply air (oxygen) into the body.

In other way round, the relaxation of the these muscles brings about expiration i.e., release of gas out of the body.

Why the water is an inorganic, transparent, tasteless, odorless, and nearly colorless chemical substance?

Answers

Why is water colorless?

It is actually not. It is weakly blue which becomes apparent when a lot of it is gathered in one place. It is definitely not very strongly colored though. That is very common. Very few pure simple substances are strongly colored. Pure salt and sugar are transparent and colorless too. In bulk they look white because the tiny crystals scatter light, but snow does the same. A liquid forms one homogeneous mass.

In nature, of course, substances are rarely pure. Therefore not so many things look colorless. It only takes a little bit of a strongly colored impurity to color the whole thing. Just look at Himalaya salt or unrefined sugar or orange juice.

Why is water tasteless?

Because we don’t need to taste it. We get a good idea of the water content of food from the feel of it. Other liquids are usually oils, which feel very different. Besides it is not all that important exactly how much water is in one particular food item, if we need hydration then we drink stuff which is definitely mostly water.

The sense of taste not registering water frees up capacity to detect other things.

Why is water odorless?

Likewise because we don’t need to smell it. There is no real evolutionary advantage to be able to instantly tell the moisture content of the air. Better to use the sense of smell to detect poisons, food nearby, relatives or strangers etc. than to tell how the weather is today. We can tell how the weather is by other means.

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.

A solution that is equal in solute concentration to that of the cytoplasm of a cell and causes a cell to neither lose nor gain water by osmosis is a(n)

Answers

Answer:

isotonic solution

Explanation:

The cell membrane is semi-permeable, so it allows to pass through certain solutes. By a process called osmosis, the water molecules move from a compartment of lower concentration of solutes to a compartment with higher concentration.

Therefore, if the concentration of solutes in the outside is higher than the concentration in the cytoplasm (hypertonic solution), the water molecules will move from the interior to the exterior. Conversely, if the cytoplasm is more concentrated than the outside (hypotonic solution), the water molecules will move from the exterior to the interior. If the cytoplasm has the same solute concentration as the outside, the solution of the outside is called isotonic, and no water net flux will be produced.

Answers

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.

Hemoglobin is the oxygen carrying compound found in human blood. It is found to contain 0.3335% iron by mass. It is already known that one molecule of hemoglobin contains four atoms of iron. What is the molecular mass of hemoglobin in g/mol

Answers

Answer:

66986.51 g/mol

Explanation:

According to this question, Hemoglobin- an oxygen carrying compound in the blood, is found to contain 0.3335% iron (Fe) by mass.

* One molecule of hemoglobin contains four atoms of iron

If 1 atom of Fe = 55.85g/mol

Then 4 atoms = 4 × 55.85 = 223.4g/mol

So there are 223.4g/mol of Fe in one molecule of hemoglobin

If hemoglobin contains 0.3335% iron by mass, this mathematically means that:

223.4g/mol of Fe ÷ molar mass of hemoglobin = 0.3335%

That is;

223.4/M.M = 0.3335/100

Cross multiply

0.3335 M.M = 22340

M.M = 22340 ÷ 0.3335

M.M = 66986.51

Hence, the molar mass of hemoglobin is 66986.51g/mol.

Animals in Cestoda have: Group of answer choices septa and parapodia proglottids and no digestive system a pharynx and gastrovascular cavity a water vascular system

Answers

Answer:

no digestive system

Explanation:

Animals in Cestoda have no digestive system so they takes nutrients through its cell wall. Cestodes have no digestive tract so they absorb nutrients from the host across the body wall. Most of the flatworms have conspicuous digestive systems while on the other hand, the digestive system of turbellarians consists of mouth, pharynx, and intestine so we can conclude that Cestoda have no digestive system to absorb nutrients like other organisms.

How can a scientist determine if two species are obligate mutualists? The scientist should observe the species in the environment to determine the types of interactions that the two species have. Then, the scientist should transplant each species alone to a new area and simultaneously transplant both species together to see if the single-species transplants die. The scientist should observe the species in the environment, determine the types of interactions that the two species have, and then add an invading species to see if it outperforms one of the other species. The scientist should observe the species in the environment, determine the types of interactions that the two species have, and then transplant both species to a new location to observe if they do better or worse than the individuals in their old location. The scientist should observe the species in the environment, determine the types of interactions that the two species have, and then remove one of the species to see if the other species does not survive.

Answers

Answer:

The scientist should observe the species in the environment to determine the types of interactions that the two species have. Then, the scientist should transplant each species alone to a new area and simultaneously transplant both species together to see if the single-species transplants die

Explanation:

When two species are obligate mutualists, both species benefit one another in such a way that one cannot survive without the other. Hence, in order to find out if two species are indeed obligate mutualists, they should be transplanted together away from other species on one side, and also transplanted individually on another side.

If they are obligate mutualists, the individual transplant would find it difficult to survive and should die in no time while the transplant done together should survive. All other factors being kept constant.

A lending library has a fixed charge for the first three days and an additional charge for each day thereafter. Saritha paid ₹27 for a book kept for seven days, while Susy paid ₹21 for the book she kept for five days. Find the fixed charge and the charge for each extra day.​​

Answers

Answer:

See the attachment.

Hope u understand

In the given question, 5₹ is the fixed charge and 3₹ is the charge for each extra day.

A fixed charge is a fee or cost that remains constant and does not vary with changes in usage or consumption.

Let the fixed charge for the first three days be x and the charge for each extra day be y.

From the given information, we can set up two equations:

For Saritha: [tex]\rm 3x + 4y = 27 -----(equation 1)[/tex]  

For Susy: [tex]\rm 3x + 2y = 21 -----(equation 2)[/tex]

We can solve for x and y by using elimination or substitution:

Using elimination, we can multiply the second equation by 2 and subtract it from the first equation:

[tex]\rm 3x + 4y = 27[/tex]

[tex]\rm - (6x + 4y = 42)[/tex]

Solving above equations, we get:

[tex]\rm -3x = -15[/tex]

[tex]\rm x = 5[/tex]

Substituting x = 5 into one of the equations, we can solve for y:

[tex]\rm 3(5) + 4y = 27[/tex]

[tex]\rm 15 + 4y = 27[/tex]

[tex]\rm 4y = 12[/tex]

[tex]\rm y = 3[/tex]

Therefore, the fixed charge is ₹5 and the charge for each extra day is ₹3.

explain the importance of dimensioning in biology​

Answers

Answer:

Even if you make a drawing to scale, it would be difficult to determine the exact precision that is needed.

It would be time consuming to measure each of the lines to determine measurement.

The basis for modern part dimensioning is the need for interchangeable parts (being able to buy something off the shelf that fits what you already have)

Explanation

When dimensioning, it is good technique to avoid listing the dimension more than once through out the drawing.

If you need to list a dimension more than once, for accuracy or ease of viewing, you must encase the dimension within a set of brackets.

Answer:

The purpose of dimensioning is to provide a clear and complete description of an object. A complete set of dimensions will permit only one interpretation needed to construct the part. Dimensioning should follow these guidelines. Accuracy: correct values must be given.
