plants make oxygen. One of thats plants produce as they make food is oxygen gas. This oxygen gas, which is an important part of the air, is the gas the plants and animals must have in order to stay alive

plants grow almost everywhere like land,water etc

The place where plants live and grow is called their habitat. Different types of plants grow all over the world in many different kinds of habitats. Plants need light and water to live. Some habitats are cold and dark. Others may be hot and dry. Plants have different ways of surviving in these different habitats

Ans :- Narendra Modi.

Nephronis the filtration unit of kidney. It consists of a tubule which is connected with collecting duct at one end and a cup – shaped structure at the other end.

This cup-shaped structure is called‘Bowman’s capsule’. Every Bowman’s capsule contains a cluster of capillaries, called ‘Glomerulus’, within the cup – shaped structure. The blood enters into Glomerulus through afferent arteriole of renal artery and leaves it through efferent arteriole.

Functioning of Nephron

1. Filtration: Filtration of blood takes place in Bowman’s capsule from the capillaries ofglomerulus. The filtrate passes into the tubular part of the nephron. This filtrate contains glucose, amino acids, urea, uric acid, salts and a major amount of water.

2. Re-absorption: As the filtrate flows along the tubule useful substances such as glucose, amino acids, salts and water are selectively re-absorbed into the blood by capillaries surrounding the nephron tubule.

The amount of water re-absorbed depends on the need of the body and also on the amount of wastes to be excreted.

3. Urine: The filtrate which remains after re-absorption is called urine. Urine contains dissolved nitrogenous waste, i.e. urea and uric acid, excess salts and water. Urine is collected from nephrons by the collecting duct to carry it to the ureter.

Bio patents is a biological patentis apatenton aninventionin the field ofbiologythat by law allows the patent holder to exclude others from making, using, selling, or importing the protected invention fora limited period of time. example :February 2013, Judge [Justice John Nicholas] ruled in theFederal Court of Australiain favour of a Myriad Genetics patent on theBRCA1gene.This was a landmark ruling, affirming the validity of patents on naturally occurringDNAsequences. However, the U.S. Supreme Court came to the opposite conclusion only a few months later. The Australian ruling has been appealed to the Full Bench of the Federal Court; submissions in the case include consideration of the U.S. Supreme Court ruling.This decision was decided in 2014, affirming Nicholas J's decision in favor of Myriad, confirming that isolated genetic material (genes) are valid subjects of patents.As of June 2015 the case was pending hearing in the High Court of Australia.[6]In October 2015 the Australian high court ruled that naturally occurring genes cannot be patented.

Trophoblasts are specialized cells of the placenta that play an important role in embryo implantation and interaction with the decidualised maternal uterus. The core of placental villi contain mesenchymal cells and placental blood vessels that are directly connected to the fetal circulation via the umbilical cord.

Anembryois an early stage of development of a multicellular diploid eukaryotic organism. In general, in organisms that reproduce sexually, anembryodevelops from a zygote, the single cell resulting from the fertilization of the female egg cell by the male sperm cell.

female reproductive system

Every 28 days or so, one matureeggis released from the ovary. This is called ovulation. After theeggis released, it moves into the fallopian tube where it stays for about 24 hours. If theegg is not fertilizedduring that time, theegg disintegrates (breaks down) and menstruation (your period) begins 2 weeks later.

The stage of the human embryo in which it gets implanted in the uterus is blastocyst.

The process of implantation can be explained as follows:

1. Fertilisation results in the formation of a diploid zygote.

2. As zygote moves through the uterus, mitotic divisions occur in the zygote that form 2, 4, 8, 16 daughter cells called blastomeres.

3. Embryo with 8 to 16 blastomeres is known as morula.

4. Morula undergoes further cleavage and develops into blastocyst; blastomeres of blastocyst get arranged into an outer layer called trophoblast and inner cells called inner cell mass.

5. Trophoblast layer of blastocyst gets attached to the endometrium while inner cell mass differentiate to form embryo.

6. After attachment, the uterine cells divide rapidly and causes the blastocyst to become embedded in the endometrium of the uterus. This leads to pregnancy.

Hormone: A chemical substance produced in the body that controls and regulates the activity of certain cells or organs.

The thyroid gland produces three hormones:

Triiodothyronine, also known as T3.

Tetraiodothyronine, also called thyroxine or T4.

Calcitonin.

Thethyroidgland produceshormonesthat regulate the body's metabolic rate as well as heart and digestivefunction, muscle control, brain development, mood and bone maintenance. Its correct functioning depends on having a good supply of iodine from the diet.

a deficiency ofiodinein the diet can cause a deficiency of thyroxine hormonein the body. The deficiency ofiodinein the diet of a person produces less thyroxine hormone and cause a disease called GOITRE. People areadvisedto useiodised saltfor cooking food so as to prevent Goitre disease.

no salt is appropriate

Use of iodised salt is advisable because it increases the iodine content in our body which rather helps in the formation of the hormone thyroxine.

Ans :- Basal metabolic rate (BMR) is the total number of calories that your body needs to perform basic, life-sustaining functions.

The female reproductive system is made up of the internal and external sex organs that function in reproduction of new offspring. In the human the female reproductive system is immature at birth and develops to maturity at puberty to be able to produce gametes, and to carry a foetus to full term.

correct answer is dans) Oestrogen

The hormones secreted by testes and ovaries are called sex hormones. Testosterone is male sex hormone produced by testes and estrogen is female sex hormone produced by ovaries. The sex hormones are named so, because these hormones are responsible for the male and female secondary sexual characters.

Hormones are the chemical substance which are grow in animals as well as in plant also.Hormones which is secreted by thyroid gland is thyroxine hormones and it's function is to control the metabolism rate of breathing, heart beat etc.

Doctor are advised to use iodised salt because the iodine is needed to thyroid gland to secret the thyroxine hormones.

Thehormonescontrolling thefemale reproductive systeminclude gonadotropin-releasinghormone(GnRH), follicle-stimulatinghormone(FSH) and leutenizinghormone(LH

Crop rotation

It prevents soil depletion,increases soil fertility,reduces soil erosion and the need for fertilizers.It also helps in controlling weeds and controls the growth of pathogens and pests in crops.

Intercropping:

1. Intercropping gives higher income per unit area than sole cropping. 2. It acts as an insurance against failure of crop in abnormal year. 3. Intercrops maintain soil fertility as the nutrient uptake is made from both layers. 4. Reduce soil runoff.

When one gland is absent, to compensate the loss as well as the other gland gets pressure maintains the normal body requirements.
