Flowering plants. After being fertilised, the OVARY starts to SWELL and develop into the fruit. ... Double FERTILISATION is the process in angiosperms (floweringplants) in which two SPERM from each pollen TUBE fertilise two cells in a female gametophyte (sometimes called an embryo sac) that is inside an ovule.follow mee.

Fertilization in flowering plants happens through a PROCESS called pollination. Pollination occurs when POLLEN grains from the anther land on a stigma.Fertilization occurs when ONE of the sperm cells fuses with the EGG inside of an ovule. After fertilizationoccurs, each ovule develops into a SEED.

You have to REMEMBER 7 traits and the DOMINANT CHARACTER in case of PEA

In rabbits, a series of multiple alleles CONTROLS coat color in the following way: C is DOMINANT to all other alleles and causes full color. The chinchillaphenotype is DUE to the cch ALLELE, which is dominant to all alleles other than C.

This is a ANSWER...☺️☺️

It is so because if we keep it open MANY house FLIES sit on them and take the PATHOGENS and come to home and sit on FOOD or sit on us


not only that

EVEN many mosquities bread in them and cause diseases

When Mendel measured two or more TRAITS (eg, HEIGHT and color) in an experiment he found that each TRAIT was transmitted independently. For example, tall or short plants can have smooth or WRINKLED seeds.

Drugs are chemicals that change the way a person's body works. You've probably heard that drugs are bad for you, but what does that mean and why are they bad?Medicines Are LEGAL Drugs

If you've ever been sick and had to TAKE medicine, you already know about one kind of drugs. Medicines are legal drugs, meaning doctors are allowed to prescribe them for PATIENTS, STORES can sell them, and people are allowed to buy them. But it's not legal, or safe, for people to use these medicines any way they want or to buy them from people who are selling them illegally.

Cigarettes, Alcohol, and Marijuana

Cigarettes and alcohol are two other kinds of legal drugs. (In the United States, adults 18 and older can buy cigarettes and those 21 and older can buy alcohol.) But smoking and excessive drinking are not healthy for adults and are off limits for kids. Marijuana is generally an illegal drug, but some states allow doctors to prescribe it to people for certain illnesses, and some have passed laws making it legal to sell marijuana to adults for personal use.

Illegal Drugs

When people talk about a "drug problem," they usually mean abusing legal drugs or using illegal drugs, such as marijuana, ecstasy, cocaine, LSD, crystal METH, and heroin to get "high."

Why Are Illegal Drugs Dangerous?

Illegal drugs aren't good for anyone, but they are particularly bad for a kid or teen whose body is still growing. Illegal drugs can damage the brain, heart, and other important organs. Cocaine, for instance, can cause a heart attack — even in a kid or teen.

Yes , PASTEURISATION KILL the BACTERIA because during pasteurisation the FOOD is heated to 72°C for 15sec . the bacteria will die in EXTREME climatical conditions.so,the bacteria will die.

To PREVENT BACK FLOW of BLOOD

The mode of reproduction in Monera is EITHER asexual or with the HELP of fission or building
Examples.
_Archaebacteria e.g.-methanobacillus,thermoplasma,etc.
_eubacteria, e.g.-, rhizobium,CLOSTRIDIUM,etc.
_cynobacteria e.g.-Nostoc,anabaena,etc.
_actinomycetes e.g.- streptomycin,MYCOBACTERIUM,etc

Hii dear here is your answer


Diabetes insipidus is a rare CONDITION that occurs when the kidneys are unable to conserve water during the PROCESS of filtering blood. ... Diabetes insipidus is CAUSED by a lack ofantidiuretic hormone (ADH), also called vasopressin, which prevents dehydration, or the kidney's INABILITY to respond to ADH.

Heterocrime GLANDS LIKE PANCREAS.

Freshwater fishes have the problem of excreting excess water because the animals TISSUES are HYPERTONIC to its surroundings. The nephrons have cilia to sweep a LARGE volume of very dilute urine from the body. Freshwater fishes CONSERVE salts by efficient reabsorption of ions from the filtrate in the nephrons.

The PROCESS is CALLED DIFFUSION.

Sexual REPRODUCTION : humans, cats, dogs, MONKEY ETC....
BINARY FISSION: amoeba.
fragmentation: spirogyra

It is AVOID by PROTANDRY

there is an EXTRA PHASE in MEIOSIS than MITOSIS

A British scientist, J.B.S. Haldane, suggested that life originated from simple inorganic molecules. He believed that when the earth was formed, it was a hot gaseous mass CONTAINING ELEMENTS such as nitrogen, oxygen, carbon, hydrogen, etc. These elements combined to FORM molecules like water (H2O), carbon dioxide (CO2), methane (CH4), ammonia (NH3), etc. After the formation of water, slowly the earth surface cooled and the inorganic molecules interacted with one another in water to form simple organic molecules such as sugars, fatty acids, amino acids, etc. The energy for these reactions was provided by solar radiations, lightning, volcanic eruptions, etc. This was proved by the experiment of Stanley L. Miller and Harold C. Urey in 1953. They took a mixture of water (H2O), methane (CH4), ammonia (NH3), and hydrogen gas (H2) in a chamber and sparks were passed through this mixture using two electrodes. After one week, 15% of the carbon from methane was converted into amino acids, sugars, etc. These organic molecules are polymerized and ASSEMBLED to form protein molecules that gave rise to life on earth.



Eukaryotic cell has large >10 um

HOPE this CLEAR your DOUBTS

Mitochondrionis a membrane-enclosed organelle found in eukaryotic cells.
Mitochondria are responsible for the production of most of the energy (or ATP) in cells. Therefore, mitochondria are ALSO known as thepower houseof cells. A mitochondrion is composed of two lipid membranes, enclosing the matrix. The inner membrane GETS folded to form numerouscristae.Cristae are the main site for ATP production. Mitochondrial matrix contains mitochondrial DNA and ribosomes
Functions of mitochondria:

They produce energy required for cells in the form of ATP.

They also REGULATE the FREE calcium ion concentration in the cytosol.

They participate in apoptosis or programmed cell death.

Phylum Echinodermata consists of ANIMALS that POSSESS water vascular system for feeding, respiration, locomotion and excretion. Eg: SEA URCHINS,Sea stars.

Testosterone is the STEROIDAL hormone produced largely by MALE gonad and helps in BODY building.This hormone is also used in production of ARTIFICIAL steroids.

It TAKES PLACE in ANAPHASE of CELL CYCLE.

Because it DIVIDES into FRAGMENTS to REPRODUCE

Dna sequencing by SANGER method can be done to identify the CLOSENESS between two species.Southern BLOT can also be done.

The REGION between TWO LUNGS is CALLED MEDIASTINUM

Phylum Mollusca is the predominant phylum in marine environments. It is estimated that 23 percent of all known marine species are MOLLUSKS; there are over 75,000 described species, making them the second most diverse phylum of animals. The name “mollusca” signifies a soft BODY, since the earliest descriptions of mollusks came from observations of UNSHELLED cuttlefish. Mollusks are predominantly a marine group of animals; however, they are known to inhabit freshwater as well as terrestrial habitats. Mollusks display a wide range of morphologies in each class and subclass, but share a few key characteristics, including a muscular foot, a visceral MASS containing internal organs, and a mantle that may or may not secrete a shell of calcium carbonate.

50 YEAR old wood....because it's growth is COMPLETED.....so it will last LONGER than the 20 year old wood

Hiiii
i HOPE it will helpfull to you and for your EXAMINATION

Cells undergoing AEROBIC respiration produce 6 molecules of carbon dioxide, 6 molecules ofwater, and up to 30 molecules of ATP (adenosine TRIPHOSPHATE), which is directly USED to produce energy, from each molecule of glucose in the PRESENCE of surplus oxygen.

Because the HAIRS of NOSE PURIFY AIR

They BREATH like .
they DONT have gills.
when they WANT to breath they SLIGHTLY COMES a little from water.

Air-liquid interface (ALI) CULTURES of mouse tracheal epithelial cells (MTEC) are a well-established model to study airway epithelial cells, but current methods require LARGE numbers of animals which is unwanted in view of the 3R PRINCIPLE and introduces variation. Moreover, stringent breeding schemes are FREQUENTLY needed to generate sufficient numbers of genetically modified animals. Current protocols do not incorporate expansion of MTEC, and therefore we developed a protocol to expand MTEC while maintaining their differentiation capacity.
