pH of oxygenated blood is 7.36 to 7.44. Blood Ph is acidity or ALKALINITY of blood. Normal or neutral ph of blood is 7.

If the pH level of blood GETTING LOWER that means the acidity level is getting higher in blood.

Higher or lower level of blood affects lung function, ENDOCRINE function, kidney function and urinary tract infection etc.

EXPLANATION:

HENCE, the ANGLE between VECTOR A and B is

In chemical reactions, when acids and BASES react together, Neutralization OCCURS.

In this type of reactions, when an acid and a base react, salt and water are produced.

The reaction involves the interaction of H+ ion with OH- ion to FORM H2O.

Equal weights of acids and base are REQUIRED to form these salt and water.

CROP rotation is the practice of growing a series of different types of crops in the same area in sequential SEASONS. Crop rotation GIVES various NUTRIENTS to the soil. A traditional element of crop rotation is the replenishment of nitrogen through the use of green manure in sequence with cereals and other crops

For example, a simple rotation between a heavy nitrogen using plant (e.g., corn) and a nitrogen depositing plant (e.g., soybeans) can help maintain a HEALTHY balance of nutrients in the soil.

Here is a list of parts of our BRAIN that controls the major part of our DAILY activities:

1. The sensation of feeling full: Separate part of the forebrain that is associated with hunger

2. Vomiting: Medulla in the hindbrain

3. PICKING up a PENCIL and riding a bicycle: Cerebellum of the hindbrain

Boxers often suffer from injuries to the head and face.

During matches, a BOXER can suffer from an injury to the head that MAKES him feel dizzy.

That might make it DIFFICULT for him to stand up or keep his balance.

A punch to the head can often do that to a boxer, which can RESULT in a knockout as WELL.

This injury happens to the Hypothalamus of the head.

Having less sodium in your diet may help you lower or avoid high blood pressure. PEOPLE with high blood pressure are more likely to develop heart disease or have a STROKE. Most people eat too much sodium, OFTEN without knowing it. The average American eats about 3,400 MG of sodium a day.

HOPE this HELPS you

And PLEASE MARK me BRAINLIEST

Metals like gold, IRON, aluminium etc. have very shiny APPEARANCE.

Air contains moisture or you can say water and oxygen.

We know that when METAL reacts with either oxygen rich air or water it will get oxidised.

Hence, when these metal get oxidised they will form a coat on it and hence loose SHINE.

Tendril is a slender whip LIKE SOFT structure that helps the PLANT in climbing for support and attachment.
these are generally the modification of leaves/stems /petiole.

I am ATP producing factory - Who am I? I am ATP producing factory I am Mitochondria.

Mitochondria is KNOWN as the POWER house of cell.

They are organelles that ACT like a digestive SYSTEM which takes in nutrients, breaks them down, and creates energy rich molecules for the cell.

The biochemical processes of the cell are known as CELLULAR respiration.

Polystyrene  

Thermocol is produced by complex material called polystyrene.

HUNDREDS of processes are done on Polystyrene for making thermocol. Polystyrene is a complex material by which thermocol, glass, PLASTIC is also made.

Polystyrene is a hydrocarbon polymer by which we can create materials like thermocol. Most of the polystyrene is present in the SOLID state. And some thermocol is in the foam.

Some info about polystyrene: .

1) Melting POINT of polystyrene: 240°C

2) Density: 1.04 g/cm³

3) SOLUBILITY: No

4) Molecular chemical formula: (C8H8)n

Biological Magnification➫ The process by which the harmful & toxic substances the tissues of organisms at higher levels in a food CHAIN.

❱ It is ALSO known as Bioamplification.

❱ It occurs when pollutants taken up by organisms at the base of the food chain reach high concentrations in the bodies of animals at the top of the food chain.

➧ Harmful Effects are:-
=======================

❱ 0rganisms at the top of the food chain are at a GREATER risk of damage due to biomagnification.

❱ It tend to have a higher risk of developing certain:-

♦ Cancers
♦ Liver failure
♦ Birth defects
♦ Brain damage
♦ HEART disease

❱ The toxins responsible for these health problems include:-

♦ Mercury
♦ Lead
♦ Chromium
♦ Cobalt
♦ Cadmium

TWO TYPES of autonomic nervous system are ...

A. Sympthatic (SNS)

B. Parasympathetic (PNS)

Effect on heart: SNS increases heart rate as a RESULT increasing cardiac OUTPUT whereas PNS decreases the heart rate.

Effect on urinary bladder: SNS stimulates contraction in inner spinster whereas PNS stimulates contraction in smooth muscles of bladder.

The ANSWER is

" False "

The GIVEN statement is completely incorrect.

Joule is USED to MEASURE the heat.

Hence we can say that heat is a UNIT of heat.

Joule is also the SI unit of heat.

Landslides occur when the slope changes from a stable to an UNSTABLE condition. A change in the STABILITY of a slope can be caused by a NUMBER of factors, acting together or alone. Natural causes of landslides include: GROUNDWATER (pore water) pressure acting to DESTABILIZE the slope.

Says the short answer is “yes” dams do destroy rivers as ecosystems.

“Many of the dams built during the 20th century have proven to be river KILLERS. Examples are numerous and notorious.”

HOWEVER he also notes the positive impact dams have had in reducing the sum of human misery and encouraging development.

“For example, the drought in the Horn of Africa was a disaster that cost the lives of millions, but the High Assam Dam spared Egypt from a drought that WOULD have been truly catastrophic,” says Thorne.

Many of the dams built in the last century were poorly designed and many are now in the process of being REMOVED. He says the EVIDENCE so far is that nature bounces back surprisingly well after dam removal

REFLECTION ( PRATIBIMBA) is the word used in SCIENCE in LIGHT THEORY.

No. many FOOD items that we consume are MOSTLY different. some are ACIDIC in nature,basic in nature and salts.
HOPE you understand....
dont forget to MARK as brainlist.....

• The taste of lemon is sour taste because lemon CONTAINS CITRIC acid so it gives a sour taste to lemons.

• Sugar gives sweetness taste because sugar contains glucose and fructose.

• BAKING soda gives a little bit of salt and bitter taste because basically, it contains sodium hydrogen carbonate.

• Curd, Amla, Tamarind, Lime, Raw MANGO these are all GIVEN a sour taste.

• when milk converted to curd the lactobacillus bacteria converts the lactose into lactic acid that's why curd contains sour taste.

• Pomegranate also gives sour taste but it will depend on the ripeness of the seeds.

• The water itself has no taste. Water is tasteless, colorless and odorless.

What it MEANS TELL and what is the QUESTION

Hii here is ur answer

The three measure that can help to check the global warming :--

(1) STOP the cutting down of tree and PLANT more trees.

(2) USE the CNG GAS at the place of petrol and disel.

(3) Stop the burning of materials which are made up of PLASTIC.

hope it helps you

Continued global warmingcould turn CURRENT marginal grasslands into deserts as rainfall patterns change. Land once incompatible with row-crop agriculture, but which provided a living to ranching families and HABITAT for prairie WILDLIFE, is being converted to row CROPS.

Only individuals in good health should be accepted as blood DONORS. Good health is DIFFICULT to define, but certain ASSOCIATED parameters may be established from a brief medical history, observation and simple tests. Staff undertaking donor health and risk assessment should be well-trained in the observation of donor appearance and detection of signs of ill health. Staff should receive explicit guidance on what to look for and when to refer a donor to a health-care PROFESSIONAL for further medical attention.

INDICATORS are substances which GIVES a prominent sign to identify the PRESENCE of acids and alkali in the solution.

Salt is produced from the REACTION of acids and bases.

So, salts are CONSIDERED as neutral.

For this reason, Indicators are not affected by salt as salt is the product of acid and base which is neutral.
