force that acts on a body moving in a circular path and is directed towards the centre around which the body is moving.

CoronaryIt is the part of the circulatory system which carries blood in the blood vessels

1.Troponin is attached to theproteintropomyosin and lies within the groove between actin filaments in muscle tissue. In a relaxed muscle, tropomyosin blocks the attachment site for the myosin crossbridge, thus preventing contraction.

suger fructose is present in the secretion seminal vesicles

option b is the answer.Functioning as an exocrine gland, thepancreasexcretes enzymes to break down the proteins, lipids, carbohydrates, and nucleic acids in food. Functioning as an endocrine gland, thepancreas secretesthe hormones insulin andglucagonto control blood sugar levels throughout the day.

Exocrine glandshaveducts- and they secrete onto a surface: examples of exocrine glands are: sebaceous and sweat glands (in the skin), salivary glands (oral), Brunner's glands. So, we have covered their basic structure and function in tissue types, and we have looked at several examples of exocrine glands in other topics.Discrete Endocrine Glands- these include the pituitary (hypophysis), thyroid, parathyroid, adrenal and pineal glands.Endocrine component of Glands with both an Endocrine and an Exocrine Function.These include the kidney, pancreas and gonads. And finally, there is a Diffuse Neuroendocrine system, which includes APUD cells.

1.Disjunctionnormally occurs during the anaphase of mitosis and meiosis (I and II). In meiosis,disjunctionhappens when homologous chromosomes move apart toward the opposite poles of the cell in anaphase I.Disjunctionagain occurs when sister chromatids separate and move away from each other during anaphase II

2.Examples ofexocrine glandsinclude sweat, salivary, mammary, ceruminous, lacrimal, sebaceous, and mucous.The major glands that make up thehuman endocrine systeminclude the:

hypothalamus.

pituitary gland.

thyroid.

parathyroids.

adrenal glands.

pinealbody.

# Endocrine Gland:1. An endocrine gland is the ductless gland. No duct is attached to the glands.

2. The internal secretions of these glands are known as hormones.

3. The secretions are directly poured into the circulating blood and reach the organ.

4. Endocrine glands are complex.

5. The important endocrine gland is pituitary, thyroid, parathyroid, adrenals, sex-glands etc.

# Exocrine Gland:1. An exocrine gland is the duct gland. They are attached with a specific duct.

2. The secretory products are enzymes, mucous and other substance.

3. The Secretions are released to the outer surface of the body or to some internal organ through a duct.

4. Exocrine glands are simple.

5. The important exocrine gland are salivary glands, liver, pancreas, sweat glands etc.

Liveris the largest gland in human body. It is also the largest (internal) organ in our body and can weigh up to 1.5 kg for a human adult. That is, about 1/50th of the body weight is because ofliver.

Seed dispersal is the movement or transport of seeds away from the parent plant. Plants have very limited mobility and consequently rely upon a variety of dispersal vectors to transport their propagules, including both abiotic vectors such as the wind and living vectors like birds.

Hormones are called chemical messengers because these are chemical compounds like proteins, steroids etc. These carry information from the organ from which they are secreted to other part of the body. It is for this reason that hormones are called as chemical messengers.

Leakage of toxic gases

d)is the correct answer

root nodulesoccur on therootsof plants (primarily Fabaceae) that associate with symbiotic nitrogen-fixing bacteria. Under nitrogen-limiting conditions, capable plants form a symbiotic relationship with a host-specific strain of bacteria known as rhizobia.

Theeffects ofglobal warmingare the environmental and social changes caused (directly or indirectly) by human emissions ofgreenhouse gases. There isa scientific consensus that climate change is occurring, and that human activities are the primary driver.Many impacts of climate change have already been observed, includingglacier retreat,changes in the timing of seasonal events(e.g., earlier flowering of plants),and changes in agricultural productivity.Anthropogenic forcing has likely contributed to some of the observed changes, includingsea level rise, changes in climateextremes,declines in Arctic sea iceextent and glacier retreat.

active needs energy coz it is against gradient and passive does not need it

1. use sandbags and floodboards to prevent water entering through doors and windows.2. stay in a high place with a means of escape3. listen to weather reports and only return to evacuated buildings if you are told it is safe to do so4. Switch off main eletric supply

If a dirty water is discharged in river or sea, the water become dirty and consumption of this water can cause harmful disease also the aquatic life can be in danger

thanks you

Answer:

Single-celled organisms are in constant contact with their environments, obtaining nutrients and oxygen directly across the cell surface. The same holds true for small and simple plants and animals, such as algae, bryophytes, sponges, cnidarians, and flatworms. Larger and more complex plants and animals require methods for transporting materials to and from cells far removed from the external environment. These organisms have evolved transport systems.

Cell membrane provides a pathway for the transport of material within and between cells.

Anelectron transport chain(ETC) is a series of complexes thattransferelectronsfromelectron donorstoelectron acceptorsviaredox(both reduction and oxidation occurring simultaneously) reactions, and couples this electron transfer with the transfer ofprotons(H+ions) across amembrane. This creates an electrochemicalproton gradientthat drives the synthesis ofadenosine triphosphate(ATP), a molecule that stores energy chemically in the form of highly strained bonds. Themoleculesof the chain includepeptides,enzymes(which areproteinsorprotein complexes), and others. The final acceptor of electrons in the electron transport chain duringaerobic respirationis molecularoxygenalthough a variety of acceptors other than oxygen such as sulfate exist inanaerobic respiration.

Thepresence of starch in leavescan be tested by Iodinetest. When we remove chlorophyll fromleafby boiling it in alcohol and then put two drops of iodine solution, its colour change to blue indicates thepresence of starch.

Edible algae based vaccination is a vaccination strategy under preliminary research to combine a genetically engineered sub-unit vaccine and an immunologic adjuvant into Chlamydomonas reinhardtii microalgae. Microalgae can be freeze-dried and administered orally.Similarly these vaccines are cost effective and no special requirements are needed.

Glycolysisis the first step involved in the process of respiration and occurs in thecytoplasmof the cell. WhileKrebsCycleis the second process of respiration which occurs in themitochondriaof the cell.Both are the process involved in respiration with the aim of fulfilling the energy requirement of the body.

Glycolysis is the metabolic process that serves as the foundation for both aerobic and anaerobic cellular respiration. In glycolysis, glucose is converted into pyruvate.Glucose is a six- memebered ring molecule found in the blood and is usually a result of the breakdown of carbohydrates into sugars.It enters cells through specific transporter proteins that move it from outside the cell into the cell’s cytosol. All of the glycolytic enzymes are found in the cytosol.

The greenhouse effect is the process by which radiation from a planet's atmosphere warms the planet's surface to a temperature above what it would be without its atmosphere. If a planet's atmosphere contains radiatively active gases they will radiate energy in all directions.
