Explanation:

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.

Answers

Answer:

Multiaxial joint

Explanation:

Joint is understood as the set of structures that allow the union of two or more bones and / or cartilage with each other. The synovial joint is a union that is established between bones that have different articular surfaces. There are factors that determine the axes of space in which a joint can be mobilized, in such a way that uniaxial, biaxial or multiaxial joints are identified. The multiaxial joint is movements in around three axes or three degrees of freedom. These joints can perform any movement. This movement that is carried out in the three axes is called circumduction movement (in a circle). The movements that a synovial joint can carry out are sliding, extension, flexion, abduction, adduction, medial rotation, lateral rotation, circumduction, protrusion, retrusion, diduction, pronation, supination, inversion, eversion, among others.

Identify and describe how bacteria, hormones, and nerves influence the health and activities of the GI tract

Answers

Answer:

The GI health is supported by a varied and rich population of bacteria. The GI processes are controlled by the coordinated efforts of the hormonal system and the neurological system. Digestion and absorption together break up diets into bodily nutrients. A healthy GI system requires a balanced diet, sufficient relaxation, and frequent physical activity, to perform best.

Explanation:

Bacteria along the GI tract have a wide range of possible health benefits, including the production of vitamins, ion absorption (Ca, Mg, and Fe), pathogens protection, histologic development, improved immune systems, and fermentation of "no-digestible food" Bacteria have a number of potential functions.

During the digestion and absorption process hormones control the different digestive enzymes, which are secreted in the stomach and bowel. In reaction to the consumption of food, for example, the  hormone gastrin induces stomach acid output. The somatostatin hormone prevents stomach acid secretion.

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.

"All honey flora are plants, but all plants are not honey flora". Justify. ​

Answers

Answer:

Beekeeping is affected by adverse climatic conditions and availability of floral resources. This study aimed to survey and characterize the flora in São João do Piauí, a semi-arid region in Piauí, Brazil, and to identify species providing resources to bees. Flowering plants were observed for 18 months, and records were taken of flowering date, growth habit, visitation and resources collected by bees. Melissopalinological analysis of honey produced in the area was performed. A total of 67 flowering plant species were recorded, of which 49 were considered as bee plants, with a predominance of herbs and shrubs. The low rainfall reduces the number of flowering species, which makes important the conservation and multiplication of species which bloom in dry season, such as Ipomoea glabra, Myracrodruon urundeuva, Sida cordifolia and Ziziphus joazeiro, as well as species that contribute to honey production such as Mimosa tenuiflora, Mesosphaerum suaveolens and Croton sonderianus.

When two populations of animals which arose from a common ancestor become geographically separated, the populations become increasingly different from one another as each adapts independently to a suite of unique ecological conditions. These populations are said to be __________. Conversely, when two populations of animals, especially those arising from unrelated ancestors, become increasingly similar as they adapt to common (shared) ecological conditions, they are said to be __________

Answers

Answer:

divergent; convergent

Explanation:

The first populations of animals are said to have evolutionally diverged while the second populations are said to have evolutionally converged.

In divergent evolution, closely related animal populations accumulate differences (due to differences in their environments) so much so that they can become different species.

In convergent evolution, different animal populations evolve similar traits (due to similarities in their environment).

Hence, the correct words to fill the gaps would be divergent and convergent respectively.

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.

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.

Blood tests can be used to check a person’s blood glucose and hormone levels. The tabular column given below shows the result of two blood tests carried out on three people to check their blood glucose levels. Person 1 is healthy.

b.Compare the glucose levels of person 3 with the glucose levels of person 1, 2 hours after drinking 75g glucose.


c.Person 3 cannot produce the hormone that controls blood glucose levels. State the hormone that person 3 cannot produce.


Pic is the table to refer.

pls answer it is urgent

Answers

Answer:

See the answer below

Explanation:

a) From the table, the glucose level of person 1 (5.4) was less than the glucose level of person 2 (5.6) after 12 hours of fasting. The glucose level of person 1  falls within the normal fasting blood sugar range (3.9 to 5.6 mmol/L) while that of person 2 was borderline higher than normal.  

b) Also from the table, the glucose level of person 3 (12.1) was greater than that of person 1 (6.4) when the glucose levels were measured 2 hours after drinking 75 g glucose. Normal after-meal sugar level ranges between 6 and 10.9 mmol/L. Hence, person 3 appears to be diabetic while person 1 seems normal.

c) The hormone that person 3 cannot produce is insulin.

Insulin helps lower blood sugar levels when necessary by signalling the liver to convert the excess sugar to glycogen which is then stored in the body. When the blood sugar falls below the normal range, another enzyme, glucagon, signals the liver to convert the glycogen back to sugar to compensate for the decrease.
