"Amber colour to urine is due to (a) urochrome. The colour of urine VARIES from pale YELLOW colour to DEEP amber due to a pigment ALSO called urobilin.

It all depends on the amount of water you drink. The more water INTAKE in the body, the lighter is the colour of the urine.

"

"The hormone which has a direct impact on urination is (b) vasopressin.

It MAINTAINS the plasma osmolality. It regulates WATER and other SUBSTANCES through V2 receptors and TRANSPORTERS.

If the water is unregulated then it may get reabsorbed by the KIDNEYS.

Vasopressin also referred to as AVP helps to regulate the concentration of urine so that body fluids are not lost further.

Today, wheat is grown on more land area than any other commercial crop and continues to be the most important food GRAIN source for humans. Its production leads all crops, including rice, maize and potatoes.Wheat is typically milled into flour which is then used to make a wide range of foods including bread, crumpets, muffins, noodles, pasta, biscuits, CAKES, pastries, cereal bars, sweet and SAVOURY snack foods, crackers, crisp-breads, sauces and confectionery (e.g. liquorice).

"Major component of urine is (c) water.

Normal urine comprises of water, urea, and salts. Urine is a liquid produced in the BODY which is excreted by the body through a process called urination.

The main constituent, i.e. more than 95% of urine is made of water. Other constituents INCLUDE urea, SODIUM, creatinine, chloride, potassium, and several other compounds.

"

The Malpighian TUBULE SYSTEM is a type of excretory and osmoregulatory system found in some INSECTS, myriapods, arachnids, and tardigrades. The system consists of branchingtubules extending from the ALIMENTARY canal that absorbs solutes, water, and wastes from the surrounding hemolymph.

"The correct PATH TAKEN by urine in our body is KIDNEY – ureters- URINARY bladder- urethra.

The ureter is the bridge between the kidney and the urinary bladder.

It collects the urine passed from the kidney and empties it into the urinary bladder.

The ureter becomes the carrier of urine from the urinary bladder to out of the body.

"

Creatinine is a COMMONLY USED as measure of kidney function.The normal creatinine clearence testvalve is 110-150ml/min in male and in FEMALE it is 100-130ml/min.The National Kidney Disease Education Program recommends calculating GLOMERULAR filtration rate from serum creatinine CONCENTRATION

Many patients worry about root canal treatment pain and may put off getting the treatment they require because of fear it will hurt. Fortunately, the anaesthetic technology used by dentists these days means the procedure can be performed with minimal discomfort. It should feel no different to having a regular filling, except it will take a while longer.

For patients experiencing significant root canal pain prior to treatment, endodontic therapy in fact provides considerable relief.

Many patients report having greater discomfort in their jaw (as a result of holding it wide open for so long) than in the treated tooth.

Your dentist should administer anaesthetic before starting any work. Due to the length of treatment, this numbing medicine may need to be “topped up”. Ask your dentist for a way to signal if you start feeling pain at any point during the treatment. Often all you need to do is raise your hand to let them know if you’re not comfortable.

If you’re feeling particularly nervous about your root canal treatment, you may be able to have an IV sedative while the work is done. This doesn’t knock you out completely, like a GENERAL anaesthetic would, but it deeply relaxes you so you don’t feel anxious and barely remember the experience.

Regular painkillers should ease any discomfort after treatment

Managing pain after root canal surgery

Root canal recovery shouldn’t be painful, but your restored tooth may swollen or SENSITIVE for a few days. During this time you can take ibuprofen or paracetamol to ease any discomfort.

You may find it more comfortable to only eat soft foods until your mouth feels back to normal.

If you experience continuing pain after taking painkillers or notice any other side-effects you should contact your dentist straight away. This is a sign of a failed root canal procedure and you may need extra dental care.

Root canal complications and problems

Despite the relatively high success rate of endodontic treatment, some patients do experience problems. Root canal complications can occur anywhere from a few days to a few years after the initial treatment.

A failed root canal can be the result of:

The dentist missing a canal during initial treatmentA canal being incompletely treated (i.e. the tip of the canal left untreated)Tissue left inside the toothA fracture to the rootLeakage of bacteria

If any of these complications arise, your dentist or endodontist will assess your tooth to see whether root canal re-treatment can be performed. The process for this is much the same as the original treatment, although it is COMPLICATED by the presence of the artificial tooth filling.

A dental implant can REPLACE a tooth which has failed root canal work

In most cases, the alternative to root canal re-treatment is extraction. Patients who don’t wish to undergo further root canal therapy may instead choose to have the problem tooth replaced with a dental bridge or implant.

If a root canal fails because of re-infection at the tip of the root, it may be possible to perform endodontic surgery. This involves making a small incision in the gum to access the root tip directly. This allows the original structure from previous treatment to REMAIN in place.

If you are concerned you may have a failed root canal, contact your dentist as soon as possible. The earlier it is treated, the less opportunity there is for the bacteria to cause more damage.

And remember, having regular dental checkups and maintaining good oral hygiene will reduce your chances .

"Option (b) NEPHRON is the correct answer.

The EXCRETORY system is FUNCTIONAL to remove the waste out of the body.

To carry out the process of waste removal EASILY, the kidneys comprise of a functional unit called nephron.

Nephron is a long tubule LIKE structure with several blood vessels. It produces urine and also enables homeostasis in the body.

"

According to the Fluid mosaic model by
Singer and Nicolson,
The LIPIDS are the seas or oceans in which the proteins were floating like icebergs in plasma membrane.
Lipid is as bilayer with polar HEADS(phosphate+choline+glycerol). and non polar TAILS(long FATTY ACID chain)
It is like a sperm in both sides of the plasma membrane

2 limitations have been adopted to increase the availability of water for agricultural PURPOSES are:

1. The incorporation of biological and ecological processes into agricultural and food production practices. For EXAMPLE, these processes could include nutrient cycling, SOIL regeneration, and nitrogen fixation.

2.Using decreased amounts of non-renewable and unsustainable INPUTS, particularly the ones that are environmentally harmful.


If this answer is helpful plzz mark it brainliest and press the thanks ❤

The uses of HARMFUL fertilizer and chemicals is causing DEATH to use ful BACTERIA and fungi
if this continued
there will be no nitrogen fixation
the farmers will be FORCED to apply more chemicals which can be dangerous

In multicellular organisms like humans the body design is very complex and the oxygen demand is quite high. The oxygen requirements of an animal cannot be met by the process of diffusion as diffusion is a very slow process.
To OVERCOME this, multicellular organisms have specialized cells and tissues for PERFORMING various necessary functions of the body such as intake of oxygen and FOOD. This helps for the higher ANIMALS like humans to meet the sufficient oxygen requirement. Unlike unicellular organisms, multicellular cells are not in direct contact with the outside environment. Therefore, diffusion SIMPLY cannot meet their oxygen requirements.

Dear Student,

Malaria is caused by Plasmodium species.

◆ ANSWER -

The ALKALOIDS used for malaria treatment are quinine and quinidine.

● Extra information -

• Quinine and quinidine are cinchona alkaloids which have as ANTIMALARIAL, antipyretic, analgesic, anti-inflammatory action.
• They act as schizonticide and gemetocide against Plasmodium.
• It is used for all i.e. prophylaxis, treatment and radical cure of malaria.

Thanks dear. Keep asking QUESTIONS...

"Reabsorption of USEFUL product takes place in the first part of nephron. It is known as proximal convoluted tubule.

Proximal convoluted tubule not only reabsorbs water but also some useful substances which may have escaped from the blood at the glomerulus.

There are more than a MILLION nephrons in the kidneys. Nephrons are made of blood vessels and renal TUBULES which help them in REMOVING water from the body and maintaining water balance too within it.

"

"Kidneys are the main filters in the human body which maintain the balance between absorption and excretion of wastes.

To ensure that the body keeps FUNCTIONING PROPERLY it is essential that kidneys keep working in a regulated manner.

The following measures will certainly help to keep kidneys healthy:

• 8 GLASSES of water a day

• Normal blood pressure

• Regularly exercise

• EATING fresh fruits and green vegetables

• Less salt intake

• Avoiding alcohol

"

"The dark coloured outer zone of the kidney is called RENAL Capsule Membrane.

A kidney has three LAYERS with the OUTERMOST being a fibrous layer and the other two being the cortex and the medulla.

The fibres that make renal capsule membrane are tough and made of collagen and elastin.

They provide support to the mass of the kidney and PROTECT the tissues against injuries.

"

The process of control of water balance and ION concentration within an organism is called osmoregulation.

It is a remarkable PHENOMENON and deals with the maintenance of constant osmotic pressure in the organism FLUID by the control of water and salt concentrations.

It is a biological phenomenon where maintenance of an internal balance between water and dissolved materials carried out by an organism independent on of environmental conditions.

Osmosis is the passage of solvent through a semipermeable membrane takes place In many marine ORGANISMS not depending on regulatory mechanisms.

Due to the CELLS have the same osmotic pressure as the sea.

What is Alkaloids?

They are a group of natural chemical compounds that contain primarily and EXTENSIVELY basic nitrogen ATOMS.

Alkaloids are classified into the FOLLOWING groups:

1)True alkaloids---Which are nitrogenous in NATURE , the heterocycle type and originate from amino acids. Examples are atropine, nicotine, and morphine.

2) Protoalkaloids are the ones which contain nitrogen and also originate from amino acids.

Examples INCLUDE mescaline, adrenaline and ephedrine.

3) Another alkaloid-like compounds is Pseudoalkaloids .

But of non-amino acids type.

This group includes, terpene-like and steroid-like alkaloids, as well as purine-like alkaloids.

Nutrition defines the ROLE of fungi in their environment. Fungi obtain nutrients in three different WAYS: They decompose dead organic MATTER. ... As parasites, fungi LIVE in or on other ORGANISMS and get their nutrients from their host.

Plant cells: Plastids: As PREVIOUSLY mentioned, plastids are DOUBLED membraned 'sac-like' organelles, GENERALLY involved in either the manufacture or storage of FOOD.
