Microbial fermentation plays a big role in the production of vitamin C or ascorbic acid.

The microbes that help in doing the same are bacteria, fungi and yeasts.

There are other vitamin-like and vitamin compounds like vitamin B2, D2 or ergocalciferol, B12, EFA’s, PQQ or pyrroloquinoline, K2 or menaquinone and ubiquinone or coenzyme Q10 which are produced through microbial fermentation.

answer is bacteria ,fungi and yeasts

The amoeba was first discovered by August von Rosenhof in 1757. It is a genus of protozoa that moves with false feet, called pseudopodia. The amoeba is a member of a whole group of amoeboid eukaryotic protists called Amoebozoa. They are heterotrophs, eating bacteria and other protists.

The earliest record of an amoeboid organism was produced in 1755 by August JohannRöselvon Rosenhof, who named his discovery "Der Kleine Proteus" ("theLittleProteus").

Heart sends the blood around the body.

TheSuez Canal is a sea-level waterway in Egypt, connecting the Mediterranean Sea to the Red Sea through theIsthmus of Suez.

Suez Canal is the answer

2.Silverfish means nothing but a jellyfish show the difference between a jellyfish and starfish will be:

Silverfish. While starfish and cuttlefish aren't actually fish, they are at least marine animals. Silverfish (Lepismasaccharina) are small wingless insects.

3.Aphrodita, or sea mouse, is a genus of marine polychaete worms found in the Mediterranean sea and the eastern and western Atlantic Ocean.

Squidarecephalopodsof theorderTeuthida, which comprises around 304 species.Like all other cephalopods, squid have a distincthead,bilateral symmetry, amantle, andarms. Squid, likecuttlefish, have eightarmsarranged in pairs and two, usually longer,tentacles. Squid are strong swimmers and certainl species can "fly" for short distances out of the water.

Every night a bat puts in 600-700 kilometres of airtime. Flying low, the animals catch insects at speeds of around 40 metres per second. At night the bat uses its hearing to navigate its way to prey. Bats catch insects continuously using echolocation, an advanced navigation system.

The bat emits ultrasonic waves with very high frequencies. Its calls are pitched at 20-100 kilohertz, a frequency that is too high-pitched for humans to hear naturally. Their sounds are reflected in the environment, hitting various objects and returning to the bat as echoes. The echo signals enable the bat to form a mental map of its surroundings.

The answer is option A

(i) Most leaves have two main parts: (1) the blade and (2) the petiole, or leafstalk. The leaves of some kinds of plants also have a third part, called the stipules. The Blade, or lamina, is the broad, flat part of the leaf.

(ii) The leaves perform three main functions such as manufacture of food, interchange of gases between the atmosphere and the plant body and evaporation of water. It is the primary function of green leaves.

Disease caused by contaminated water:

1. Cholera

2. Typhoid

Aeration is the name of process

Moss plants produce a large number of male gametes to increase the chances of fertilisation, as the eggs are located in the archegonium and the male gametes have to swim in water to reach the eggs for fertilisation to occur.

The male gametes are calledantherozoids.

Working of heart

The heart has superior and inferior vena cava. They carry deoxygenated blood from the upper and lower regions of the body respectively and supply the deoxygenated blood to the right auricle of the heart.

The right ventricle contracts and passes the deoxygenated blood into the two pulmonary arteries, which pumps it to the lungs where the blood is oxygenated. From the lungs, the pulmonary veins transport the oxygenated blood to the left atrium of the heart.

The left atrium contracts and through the auriculo-ventricular aperture (bicuspid valve), the oxygenated blood enters the left ventricle.

The blood passes to aorta from the left ventricle. The aorta gives rise to many arteries that distribute the oxygenated blood to all the regions of the body.

Since the blood goes twice through the heart, it is known asdouble circulation.

Hope this helps! All the best

The complete digestion and absorption of Food takes place in the Small Intestine of the Alimentary Canal.

The enzymes secreted by Liver and Pancreas helps in complete Digestion.

The finger - like Projections (Villi) present on the inner walls of Small Intestine absorb the food.

the enzymes in the pancreatic juice help in the digestion of food we consume

enzymes helps in food digestion

pancreatic juice helps in the digestion of proteins

Your correct answer is food

nanometer

Units used to measure atomic radius: Angstroms (Å): This the most common unit used. Equivalent to1.0x 10-10 meters. Nanometer (nm): Equivalent to1.0x 10-9 meters.

Observations:

1. Binary fission in Amoeba shows division of nucleus by stretching.

2. Nucleus breaks into two nuclei slowly and cytoplasm also divides (cytokinesis).

3. Two small daughter cells (Amoebae) are formed at the end.

Lamarckism, a theory ofevolutionbased on the principle that physical changes in organisms during their lifetime—such as greater development of anorganor a part through increased use—could be transmitted to their offspring. The doctrine, proposed by the French naturalistJean-Baptiste Lamarckin 1809, influenced evolutionary thought through most of the 19th century. Lamarckism was discredited by most geneticists after the 1930s, but certain of its ideas continued to be held in theSoviet Unioninto the mid-20th century.

Lamarck gave 3 principles

Lamarckism , a theory of evolution based on the principal that physical changes in organisms during their lifetimes , such as great development of an organ or part through increased use , could be transmitted to their offspring's

theory of acquired character

Lamarckism, or Lamarckian inheritance, also known as "Neo-Lamarckism", is the notion that an organism can pass on to its offspring physical characteristics that the parent organism acquired through use or disuse during its lifetime

the theory of evolution is given by Charles darwin

Lamarckis best known for hisTheoryof Inheritance of Acquired Characteristics, firstpresentedin 1801 (Darwin's first book dealing with natural selection was published in 1859): If an organism changes during life in order to adapt to its environment, those changes are passed on to its offspring.

Yes. The theory is called as lamarckism

Stanley Cohen and Herbert Boyer's historic experiment used techniques to cut and paste DNA to create the first custom-made organism containing recombined or "recombinant" DNA.

1. Plastic is not degradable. Plastic is a harmful product which can't be degrade by micro organisms easily. So this affects the fertility of soil.

2. Plastic totally fulfill all rivers , seas , etcs.

3. Animals consume plastic bags which effect their health

Boys of senior classes have broader shoulders and wider chests than junior boys because of puberty. During puberty, secretion of hormones increases which are followed by these changes.

Plastic are a harmful hazard which harm the environment as they neither decompose in soil nor in water bodies. Burning them produces harmful gases and fumes which create suffocation and breathing problems whereas cloth bags can be recycled again and again for different uses

Spores are formed inside a thick outer covering called the cyst wall that protects the spores from harsh and unfavorable conditions. This helps them in surviving for a longer time.

a. Eachsporeis covered by a hard protective thick walltoenable themsurviveunder unfavourable conditions like lack of moisture, lack of nutrients and extreme temperature.

Thus, thespores can survivefor alonger periodoftime

b. The primary purpose of aflowerisreproduction. Since theflowersare thereproductive organs of plant, they mediate the joining of the sperm, contained within pollen, to the ovules — contained in the ovary. Pollination is the movement of pollen from the anthers to the stigma.

.Stamens are the male reproductive parts of flowers. A stamen consists of an anther (which produces pollen) and a filament. The pollen consists of the male reproductive cells; they fertilize ovules.

A bryophyte spore is haploid. A haploid cell has one set of chromosomes.
