amoeba is the option a

a) nucleus b) pseudopodia c) food particles

eoba is the option a

amoeba is the correct answer

Multiple fission at the cellular level occurs in many protists, e.g. sporozoans and algae. The nucleus of the parent cell divides several times by amitosis, producing several nuclei. The cytoplasm then separates, creating multiple daughter cells.

2)Fission takes place in single celled organisms. It is further divided into two types binary fission and multiple fission.

1- BINARY FISSION

In binary fission two single celled organisms are produced through mitotic division. In this process, the nucleus and cytoplasm are divided as well, which results in two single celled organisms that are identical to the parent cells.

Examples of some organisms that reproduce by using binary fission are Amoeba, paramecium, etc.

- MULTIPLE FISSION

Under certain conditions, the nucleus will divide a number of times inside the cell itself, producing many nuclei. Once that happens, each of the nuclei that are formed gets enclosed by cytoplasm. This results in separate and individual units. Newly born cells come out of the parent cell after breaking the wall and start living as a new organism.

Examples of organism that reproduce through this method are Plasmodium, paramecium and amoeba etc.

1)Fission, in biology, is the division of a single entity into two or more parts and the regeneration of those parts into separate entities resembling the original. The object experiencingfissionis usually a cell, but the term may also refer to how organisms, bodies, populations, or species split into discrete parts.

d is the correct option

No. of moles of atoms = weight / atomic weight.

100 gms of N₂ = 100/2 x 14 moles = 100/28 moles

Number of molecules = 100 / 28 x 6.022 x 10²³

Molar mass of N₂ = 2 x molar mass of monoatomic N

Molar mass of N₂ = 2 x 14.0067 = 28 moles.

Number of molecules = 100/28 x 6.022 x 10²³

No. of atoms = 2 x 100/28 x 6.022 x 10²³ = 43.01 x 10²³

For NH₃ :-

100 gm of NH₃ = 100/17 moles

Number of molecules = 100/17 x 6.022 x 10²³ molecules

No. of atoms in NH₃ = (1 + 3) = 4 x 100/17 x 6.022 x 10²³ =141.69 x 10²³ atoms.

Therefore, NH₃ has more atoms than N₂.

Ans:- law of constant composition states that a given chemical compound always contains its component elements in fixed ratio and does not depend on its source and method of preparation.

worng ans

In chemistry, the law of definite proportion, sometimes called Proust's law or the law of definite composition, or law of constant composition states that a given chemical compound always contains its component elements in fixed ratio and does not depend on its source and method of preparation.

Thelaw of definite proportion, sometimes calledProust's laworthe law of definite composition, orlaw of constant compositionstates that a givenchemical compoundalways contains its component elements in fixed ratio (by mass) and does not depend on its source and method of preparation. For exampleoxygenmakes up about8/9of the mass of any sample of purewater, whilehydrogenmakes up the remaining1/9of the mass. Along with thelaw of multiple proportions, the law of definite proportions forms the basis ofstoichiometry.

option D is correctaction of ptyalin on starch stops

its answer is option b that is action gets reduced

action of ptyalin on starch stops

d right answer hoga got it

action of ptylin on starch is reduced

d)As every enzyme has optimal pH for their action, lime juice inhibits the action of ptylin on starch by making pH more acidic which is not suitable for action of ptylin.

option no. (d) action of ptyalin on starch stops. is right answer

action of Ptyline on sr

option (d) is the right answer

Ptyalin (that acts on starch) is most active at a pH of 6.8 and the pH oflime juiceis less than 4 (acidic), therefore,when lime juiceis taken, the action of ptyalin on starch will be reduced.

If we take food rich in lime juice, the action of ptyalin on starch is reduced because lime juice contains a mild organic acid (citric acid) and consuming food with lime juice will cause a lowering a pH in the mouth. As a consequence, the activity of ptyalin will be inhibited if pH drops below the optimum range of 5.6-6.9.

(A) action of ptyalin on starch is enhanced

(b) action of ptyalin on starch reduced

action ofptyalin on starch is enhanced

b answer is correct up to question

Action of ptyalin on starch is reduced

option (d)is the correct answerif we take food rich in lime juice then the action of ptyalin on starch stop

action of ptyalin on starch stops .

action of ptyalun on starch stops because it works an 6.4 pH

Ptyalin works best in the pH range 5.6-6.8.Lime juice being acidic reduces the pH of mouth,that is why action of ptyalin is reduced in presence of lime juice.

action of ptyalio on starch stop

action of ptyalin on strach is enhanced

action of ptyalin on starch is reduced(b)

action of ptyali on starch is reduced

If we take food rich in lime juice, then action of ptyalin on starch is reduced. Starch is attacked by ptyalin, the α -amylase in saliva. However, the optimal pH for this enzyme is 6.7-6.8 and its action is inhibited by the addition of lime juice, because, lime -juice makes the mediunt more acidic which is not suitable for ptyalin action, so the action of ptyalin on starch is reduced.

Reflex actions are sudden, involuntary reactions of the body in response to stimuli. ... Somatic nervous system is responsible for reflex arcs. Reflex arc is the path of impulses in the reflex action. Reflex actions occur both from the brain and spinal cord which are the parts of the central nervous system.

(A) is correct option

A rainwater harvesting system has three main stages

1) Collecting & transporting rainwater

This is done through catchment areas & conduits. The catchment of awater harvesting systemis the surface which receives rainfall directly.

It can be a paved area like the terrace or courtyard of a building. Conduits are the pipelines that carry rainwater from the catchment or rooftop to the harvesting sysstem.

2) Filtration

A filter unit is a chamber filled with filtering media to remove debris and dirt from water before it enters the storage tank or recharge structure.

3) Storage in tanks for reuse / Recharging the groundwater levels

The harvested water can now be stored in storage tanks for immediate usage, which are designed according to the water requirements of the society.

Existing non-potable water storage tanks in the society can also be used to store the harvested rainwater.

Recharging the groundwater levels

The collected rainwater can also be used to recharge the groundwater levels by using structures like dug wells, borewells, recharge trenches and recharge pits.

Rainwater harvestingis theprocessof collection ofrainwaterfrom surfaces on whichrainfalls, filtering it and storing it for multiple uses.

Rainwater harvesting is the accumulation and storage of rainwater for reuse on-site, rather than allowing it to run off.

rainwater harvesting is the process in which rain water is made to use

it is storage of water and make it unable
