Cuscuta reflexa, Orobanche aegyptiaca, Striga asiatica etc. are the examples of total parasitic plants. Partial parasites are those which are partially dependent on their hosts. Partial parasitic plants are usually chlorophyllous therefore they are dependent on their hosts for water and nutrients only.

Vitamins and minerals are considered essential nutrients—because acting in concert, they perform hundreds of roles in the body. They help shore up bones, heal wounds, and bolster your immune system. They also convert food into energy, and repair cellular damage.

The vacuum prevents conduction. The tight stopper prevents air from entering or leaving the flask, so convection isn't possible either. If heat can't escape from a vacuum flask, it follows that heat can't penetrate into a flask from outside either.

It protects us from harmful uv rays

Sia ? 6 years, 10 months ago

The ozone layer acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation (UVR) from the sun, protecting life on Earth from its potentially harmful effects. When the sky is clear, there is an inverse relationship between stratospheric ozone and solar UVR measured at the Earth's surface.

Caterpillars are larval forms of insects such as butterfly. Caterpillars shed their skin 3-5 times while they grow and this process is called molting.  Their skin never grows as skin of human does, so while growing they have to crawl out of their skin when their skin becomes too tight. After first molting they bring new skin cover and in the mean time some caterpillars also eat their shed old skin. After  they grow more, then again shed their skin.
 In case of humans, shedding of whole skin does not occur as when human body grows, skin cells also grow. Shedding of only dead skin cells occur in case of human beings.

The ABO blood group is the most important of all the blood group systems.  There are four different ABO blood groups - A, B, AB & O determined by whether or not an individual's red cells carry the A antigen, the B antigen, both A and B antigens or neither.

Normal healthy individuals, from early in childhood, make red cell antibodies against A or B antigens that are not expressed on their own cells.  These naturally occurring antibodies are mainly IgM immunoglobulins.  They attack and rapidly destroy red cells carrying the corresponding antigen.  For example, anti-A attacks red cells of Group A or AB.  Anti-B attacks red cells of Group B or AB. If ABO incompatible red cells are transfused, red cell haemolysis can occur.  For example if group A red cells are infused into a recipient who is group O, the recipient's anti-A antibodies bind to the transfused cells.  An ABO incompatible transfusion reaction may result in overwhelming haemostatic and complement activation, resulting in shock, renal failure & death.

The female silk moth lays hundreds of eggs at a time. The eggs are carefully stored on the strips of a cloth or paper and sold to silkworm farmers. The eggs are kept under suitable conditions of temperature and humidity. The eggs are warmed to a suitable temperature for the larvae to hatch from eggs. The larvae are kept in clean bamboo trays along with freshly chopped mulberry leaves. After 25 to 30 days the caterpillars stop eating and move to tiny chambers of bamboo in the tray to spin cocoons which develop the silk moth.

Processing silk:

A pile of cocoons are kept under the sun or boiled or exposed to steam which separates out the silk fibres.

The process of taking out threads from the cocoon for use as silk is called reeling the silk.

An elephant has a trunk which it uses as a nose because of which it has a strong sense of smell. It also uses its trunk for picking up food. Its tusks are modified teeth which can tear the bark of trees that elephant loves to eat.

Large ears of the elephant help it to hear even very soft sound. They also keep the elephants cool in hot and humid climate.

The day to day condition of the atmosphere at a place and time with respect to the temperature, pressure, humidity, wind speed and wind direction, sunshine, clouds, rainfall etc. is called weather at that place.

If the temperature of air around us on a particular day is high we say that the weather is hot today and if the temperature on a day is low we say that the weather is cold today.

Similarly if there is lot of water vapour in the air we say that the weather is too humid and if there is rain we say that the weather is rainy.

Stomata is located in the bottom side of the leaf Takes in carbon dioxide and releases oxygen

Yogita Ingle 6 years, 10 months ago

Stomata are microscopic pores found mostly on the underside of leaves. They are located in the epidermal tissue. Each stoma is surrounded by a pair of specialized, kidney shaped cells called guard cells, which possess chlorophyll and regulate the opening and closing of stomata. The primary function of stomata is to allow gaseous exchange during photosynthesis and respiration between the plant's internal tissues and the atmosphere. The process of transpiration also takes place through stomata.

Suhani Goel 6 years, 10 months ago

Stomata is situated in guard cells.. And it is the main part of plant for the process of inhale and exhale of co2 and o2
