Answer 2  · Peptic ULCERS are sores that develop in the lining of the stomach, lower esophagus, or small intestine. They're usually formed as a result of inflammation caused by the bacteria H. pylori, as well as from erosion from stomach acids.

Causes of peptic ulcers

Different factors can cause the lining of the stomach, the esophagus, and the small intestine to break down. These include:

•Helicobacter pylori (H. pylori), a type of bacteria that can cause a stomach infection and inflammation

•frequent use of aspirin (Bayer), IBUPROFEN (Advil), and other anti-inflammatory drugs (risk associated with this behavior increases in women and people over the age of 60)

•smoking

•drinking too much alcohol

•radiation therapy

•stomach cancer

Ans3 Osmoregulation is the process of maintaining an internal balance of salt and water in a fish's body. A fish is, after all, a collection of fluids floating in a fluid environment, with only a thin SKIN to separate the two.

Ans4 Peristaltic movement is the contraction and relaxation of the muscles in the food pipe which brings the food down the pipe and into the stomach .

Ans5 The plant will not be able to transport water from roots to different parts ofplant. Hence it will wilt and ultimately die.

Ans6. Photolysis, chemical process by which molecules are broken down into smaller units through the absorption of light.

Ans7 The plant closes these pores when carbon dioxide is not required for photosynthesis. Guard cells performs the opening and closing of these pores. The guard cells swell when water flows into these pores and stomatal pores GET open, and as the water shrinks the guard cell closes.

Ans8 Ans. Phloem transports food materials from the leaves to different parts of the plant. The transportation of food in phloem is achieved by utilizing energy from ATP which helps in creating osmotic pressure that transport food from the area of high concentration to low concentration.

Ans9 Ans. Saliva contains a digestive enzyme called salivary amylase, which breaks down starch into sugar. It also moistens the food for easy swallowing.

Ans10 Since ventricles have to pump blood into various organs, they have thicker muscular walls
than atria do.

Ans 11 The endocrine is called the DUCTLESS glands because there is no ducts in the glands. The products such as hormones are secreted and goes directly to the blood stream. So there is no need for glands to collect and distribute the products, it just goes straight to the blood. Exocrine glands are the ones that do require ducts.

Ans12 Testosterone is secreted by male testis. The testis is responsible for all the changes in human body during puberty. For example: development of secondary sexual characters.

Ans13 1. Rate of heart beat.
2. Breathing movements

Ans14  When we touch Mimosa pudica (touch me not ), our touch acts as stimulus for plant and it closes its leaves in return. Some chemicals are released from the stem when we touch the plant. These chemicals force water to move out of the cell leading to the loss of turgor pressure.so touch me not droop down on touching.

Green manure is made by farmers in the crop field.Farmers grow some LEGUMINOUS crops such as clister BEANS ,cowpea and HORSE gram.When these plants are grown up then uprooted not cleared away from the field.After one or two months these legumes get DECOMPOSED by the action of MICROBES and turns into green manure. its role in agriculture is to:
1.increase soil fertility
2.make the soil spongy

In agriculture, green manure is created by leaving uprooted or sown crop parts to wither on a field so that they serve as a mulch and soil AMENDMENT.[1] The plants used for green manure are often cover crops grown primarily for this purpose. Typically, they are ploughed under and incorporated into the soil while green or SHORTLY after FLOWERING. Green manure is commonly associated with organic FARMINGAND can play an important role in sustainable annual cropping systems.

Protozoa is called as unicellular because it has only one cell, which has no nucleus and distinct organelles. Protozoa are non-phototrophic, unicellular, eukaryotic microorganisms with no cell walls. This diverse GROUP of over 65,000 species GENERALLY share these BASIC attributes. Looking DEEPER, this group can be extremely complex and variable. In FACT, the protozoa are often described as the pinnacle of unicellular complexity.

Symmetry in animals are mainly of 3 types:
1. Radial - BODY is divisible into two equal halves by any plane which passes through the CENTRE e.g. starfish, jellyfish
2. Biradial - body divisible into two equal halves by only two vertical planes.e.g.sea anemone
3. Bilateral- body divisible into equal right and left halves when cut by a vertical plane passing through the median LONGITUDINAL body axis.e.g.cockroach, man.

HERE IS YOUR ANSWER

There are about a hundred of oppositions for construction of dams and multipurpose projects.

This is because, when dams are built, it LEADS to huge deforestation LEADING to disastrous consequences.
Then the wildlife of the place is AFFECTED and animals native to the local area should MIGRATE or die.
A large amount of vegetation under the stores water leads to slow decay and release of greenhouse gases like methane.

The retina is the innermost, light-sensitivelayer, or "coat", of SHELL tissue of the eye of most vertebrates and some molluscs. The optics of the eye create a focused two-dimensional image of the visual world on the retina, which translates that image into electrical neural impulses to the brain to create visual perception, the retina serving much the same function as film or a CCD in a camera.

The retina consists of several layers of NEURONS interconnected by synapses. The neural retina refers to the three layers of neural cells (photo receptor cells, bipolar cells, and ganglion cells) within the retina, which in its entirety comprises ten distinct layers, INCLUDING an OUTER layer of pigmented epithelial cells. The only neural cells that are directly sensitive to light are the photoreceptor cells, which are of two types: rods and cones. Rods function mainly in dim light and provide black-and-white vision while cones are responsible for the perception of colour. A third type of photoreceptor, the photosensitive ganglion cells, is important for entrainment and reflexive responses to the brightness of light.

sacred grove or sacred woods are any grove of trees that are of special religious importance to a particular culture. Sacred groves feature in various cultures throughout the WORLD. They were IMPORTANT features of the mythological landscape and cult practice of Celtic, Baltic, Germanic, ancient Greek, Near Eastern, Roman, and Slavic POLYTHEISM, and were also used in India, Japan, and West Africa. Examples of sacred groves INCLUDE the Greco-Roman temenos, the Norse hörgr, and the Celtic nemeton, which was largely but not exclusively associated with Druidic practice. During the Northern Crusades, there was a COMMON practice of building churches on the sites of sacred groves. The Lakota and various other North American tribes consider particular forests or other natural landmarks to be sacred.

Ancient holy trees remain in the English and Estonian countryside and are mentioned often in folklore and fairytales.

30 million NUCLEOSOMES are PRESENT in MAMMALIAN cells

BACKGROUND: Use of nucleic acid testing (NAT) in donor infectious disease screening improves transfusion safety. Advances in NAT technology include improvements in assay sensitivity and system AUTOMATION, and real-time viral target discrimination in multiplex assays. This article DESCRIBES the sensitivity and specificity of cobas MPX, a multiplex assay for detection of human immunodeficiency virus (HIV)-1 Group M, HIV-2 and HIV-1 Group O RNA, HCV RNA, and HBV DNA, for use on the cobas 6800/8800 Systems.
STUDY DESIGN AND METHODS: The specificity of cobas MPX was evaluated in SAMPLES from donors of blood and source plasma in the United States. Analytic sensitivity was determined with reference standards. Infectious window periods (WPs) before NAT detectability were calculated for current donor screening assays.
RESULTS: The specificity of cobas MPX was 99.946% (99.883%-99.980%) in 11,203 blood donor samples tested individually (IDT), 100% (99.994%-100%) in 63,012 donor samples tested in pools of 6, and 99.994% (99.988%-99.998%) in 108,306 source plasma donations tested in pools of 96. SEVEN HCV NAT-yield donations and one seronegative occult HBV infection were detected. Ninety-five percent and 50% detection limits in plasma (IU/mL) were 25.7 and 3.8 for HIV-1M, 7.0 and 1.3 for HCV, and 1.4 and 0.3 for HBV. The HBV WP was 1 to 4 days shorter than other donor screening assays by IDT.
CONCLUSION: cobas MPX demonstrated high specificity in blood and source plasma donations tested individually and in pools. High sensitivity, in particular for HBV, shortens the WP and may enhance detection of occult HBV.

SPINAL CORD -

It's a long tubular structure made up of nerve cell which runs from Medulla oblangata to lumber region. It's a part of CNS, brain and spinal cord combinly forms CNS.
____________________________________

Location -

It is located mid-dorsally in the neural canal of the vertebral column. It extends from Medulla oblangata to lumber region.
____________________________________

Covering (Meninges) -

Like brain, Spinal cord is also covered by three membranes. These are -
1. Piamater - Innermost and thin layer.
2. Arachnoid membrane - Middle and wavy layer.
3. Duramater - outermost and TOUGH layer.
____________________________________

Structure -

External structure - It is 40-45 cm long in adult individual. At different levels, it's diameter is also differ. It's diameter is enlarged in cervical and lumbar region. It's cervical enlargement extends upto fourth cervical. At the site of cervical region nerves are distributed to arms.
At second lumber region numerous branches of spinal cord arises, these spinal nerves COLLECTIVELY known as Cauda equina (horse's tail). It ends at Conus medullaris.

Internal structure - Internal structure of spinal cord can be seen by cross section. Spinal cord is divided into two HALVES (left and right) through through two indentations which are Posterior median sulcus and Anterior median fissure. In the section on spinal cord the inner butterfly shaped area is FILLED with grey matter. Spinal nerves are arises from the segments of each side of vertebral column.
____________________________________
Functions -

✓ It is known as Center of Spinal reflex action.
✓ Spinal cord transmits impluses from and to the brain.

Animal can travell ONE PLACE to the ANOTHER place but PLANT can not travel

Plants really plays an important role in our life.
it's BCZ of plant that we survive.
plants takes carbon di oxide and realeses oxygen.
oxygen help in breathing .
it's bcz of plant that we are ABLE to GET water.
plants fulfil our basic nessecities example
provide us food clothing shelter and it help us in creating THINGS for better and comfortable life .
