Pteridophyta-They have vascular tissues.

-They have well differentiated BODY thus have PROPER ROOT system.

Here is your ans The exchange of oxygen and carbon DIOXIDE in the leaf (as well as the loss of water vapor in TRANSPIRATION) occurs through pores called STOMATA (singular = STOMA). Normally stomata open when the light strikes the leaf in the morning and close during the NIGHT.

An ankle sprain is an INJURY to the tough bands of tissue (ligaments) that surround and connect the bones of theleg to the foot. The injury typically happens when you ACCIDENTALLY TWIST or TURN your ankle in an AWKWARD way. ... Sprained ankles most commonly involve injuries to the ligaments on the outside of the ankle.

Exoskeleton:

1. Hard part that lies outside of the body is called exoskeleton.

2. Develops from ectoderm.

3. Mostly non-LIVING e.g. scales, hair, HORNS, feathers.

4. The exoskeleton covers the MUSCLES and soft tissue of the animal, providing better leverage for muscular movement.

5. This molting process takes place various times over the lifetime of the animal.

Endoskeleton:

1. Hard part that lies inside of the body is called endoskeleton.

2. Develops from endoderm.

3.They are less protective than exoskeletons

4. They are living, e.g. Bones, cartilages.

5. Another advantage of endoskeletons is that they GROW as the organism GROWS in size.

Solar electric systems use solar CELLS to convert the Sun's radiant energy into electricity. This is done using a principle known as the photovoltaic effect. Since a solar cell only GENERATES about 1-2 Watts of power, it is necessary to combine them into solar power panels in ORDER to generate more power.

There are lots of ways we use solar energy. We can harness the sun's energy by using solar collectors. These collectors enable US to use the heat from the sun to warm our homes and heat our water. They can be installed anywhere the sun shines but are usually installed on ROOFS for maximum sun exposure.

This is a list of Asian countries and DEPENDENT territories by population SORTED by normalized demographic projections.

This is a list of countries and dependent territories by population. It includes sovereign STATES, inhabited dependent territories and, in some cases, constituent countries of sovereign states, with inclusion within the list being primarily based on the ISO standard ISO 3166-1. For instance, the United Kingdom is considered as a single ENTITY while the constituent countries of the Kingdom of the Netherlands are considered separately. In addition, this list includes certain states with limited recognition not found in ISO 3166-1.

Land fragmentation is defined as the situation in which a single FARM or OWNERSHIP CONSISTS of numerous spatially separated PLOTS [5]. ... This indicates that agricultural land fragmentation is a WIDESPREAD phenomenon in highland areas of the country.

Background:

Cigarette smoking is an established and modifiable risk factor for periodontitis. Periodontitis appears to be dose-dependent on smoking. The purpose of this study was to assess a reliable MARKER of tobacco smoke exposure (salivary cotinine) chairside and to confirm the QUANTITATIVE association between smoking and chronic periodontitis.

Materials and Methods:

Saliva samples from 80 males, aged 30–60 years, with chronic periodontitis, were evaluated chairside using NicAlert™ cotinine test strips (NCTS). Patients were divided into two groups: A (cotinine negative) and B (cotinine positive). Plaque index (PI), Gingival index (GI), gingival bleeding index (GBI), probing pocket depth (PPD), clinical attachment level (CAL), and gingival recession (GR) were compared between the two groups and among the SUBJECTS of GROUP B.

Results:

Comparison showed that the severity of PPD (P<0.001), CAL (P<0.001), and GR (P<0.001) was more in group B than in group A. Severity of all periodontal parameters increased with increased salivary cotinine among the subjects in group B.

Mainly its communication and reach. The government fails to communicate it to all PEOPLE leading to lack of awareness. Lack of awareness leads to PARENTS not knowing about the programmes. Sometimes MISUNDERSTANDING of certain INFORMATION makes certain people to simply pass the programs. The reach of centers distributing the vaccines is also sparse and some children from hard to reach areas miss the date.

Domestic waste disposal is an issue that is important to the management of any urban area. Cities without a functioning waste-disposal plan face risks of disease RUNNING rampant and economic activity GRINDING to a halt. The majority of North American cities use the sanitary-landfill method of waste disposal, which has served FAIRLY well for quite a while; however, in situations where SPACE is at a premium, incineration and material-recycling-based waste disposal are more likely to come to the FOREFRONT.

It is a juice produced by liver.

Bile or GALL acts to some extent as a surfactant, helping to emulsify the lipids in food. Bile salt anions are hydrophilic on one side and hydrophobic on the other side; consequently, they tend to aggregate around droplets of lipids (triglycerides and phospholipids) to form MICELLES, with the hydrophobic sides towards the fat and hydrophilic sides facing outwards. The hydrophilic sides are negatively charged, and this charge prevents fat droplets coated with bile from re-aggregating into larger fat particles. Ordinarily, the micelles in the duodenum have a diameter around 14–33 μm.[citation needed]

The dispersion of food fat into micelles provides a greatly increased surface area for the action of the enzyme pancreatic lipase, which actually digests the triglycerides, and is able to reach the fatty core through GAPS between the bile salts. A triglyceride is broken down into two fatty acids and a monoglyceride, which are absorbed by the villi on the intestine walls. After being transferred across the intestinal membrane, the fatty acids reform into triglycerides (re-esterified), before being absorbed into the lymphatic system through lacteals. Without bile salts, most of the lipids in food would be excreted in faeces, undigested.[citation needed]

Since bile increases the absorption of fats, it is an important part of the absorption of the fat-soluble substances,[4] such as the vitamins A, D, E, and K.[citation needed]

Besides its digestive function, bile serves also as the route of excretion for bilirubin, a byproduct of red blood CELLS RECYCLED by the liver. Bilirubin derives from hemoglobin by glucuronidation.

Bile tends to be alkali on average. The pH of common duct bile (7.50 to 8.05) is higher than that of the corresponding gallbladder bile (6.80 to 7.65). Bile in the gallbladder becomes more acidic the longer a person goes without eating, though resting slows this fall in pH.[5] As an alkali, it also has the function of neutralizing excess stomach acid before it enters the duodenum, the first section of the small intestine. Bile salts also act as bactericides, destroying many of the microbes that may be present in the food

1) it is a heratable....if you have family member with bipolar disorder...then u may b at risk of it.
2) stress....if u have a very bad experience,DEATH of parents or close relative, loosing JOB, moving to new place nd missing previous one.
3) high alcohol nd drugs use can INCREASE CHANCES of bipolar disorder
4) being women....as women have 3 TIMES more possiblity of having this disorder.

Yes the SIZE and number of cells depend upon the size of the organism.
As a general RULE, the size of the organism DEPENDS on the number of cells. There are limits to how large a single cell can grow, so UNICELLULAR organism are mostly microscopic. As the number of cells in the organism increases, the organism size also increases.

There are MANY FOOD items,

BRINJAL, potato, cauliflower, FRUITS, methhi etc.

Excretion in ANIMALS take place by many methods some of them are as follows :

• Sweat is released from our body by many different processes.

This sweat CONTAINS many chemicals LIKE urea , etc.

• The liquid waste that is separated by kidneys from blood is known as urea.

This urea is released from the body in the FORM of urea.
