Amoeba is unicellularDigestion in amoeba is said to be intracellular because amoeba is a SINGLE celled organism, so the digestion takes place inside the cell. It obtains its nutrition in a heterotrophic MODE. Amoeba can form pseudopodia. It engulfs the food with its pseudopodia. When the food enters its body, the amoeba forms a food vacuole around it which contains certain ENZYMES to digest the food. THEREFORE, the correct answer is option A.

croorganism or MICROBE is an organism which is microscopic, which means so small that people cannot see them with naked eye. Microorganisms include bacteria, fungi, archaea, protists and viruses, and are among the EARLIEST known LIFE forms.2. Bacteria are difficult to see with a bright-field compound microscope for several reasons: They are small: In order to see their shape, it is NECESSARY to use a magnification of about 400x to 1000x. They are transparent: Bacteria will show their color only if they are present in a colony.If you satisfy on my answer please mark it BRAINLIEST ✏️✏️✏️✏️✏️✏️✏️

Lysomes are called the SUICIDAL bags of cellThis is because Lysosomes are the cellular ORGANELLES that contain digestive enzymes that break down waste MATERIALS, FOREIGN materials and foreign particles that entered cell.

Cellular Respiration Stage III: Electron TransportElectron transport is the final stage of aerobic respiration. In this stage, ENERGY from NADH and FADH2, which result from the KREBS cycle, is transferred to ATP.

king PROCESS in plants is called as photosynthesis and synthesized food is STORED as carbohydrates (glucose as well as starch). Plants are known as photoautotrophs or photosynthetic organisms which means that they are able to synthesize their food DIRECTLY from carbon DIOXIDE and water using energy from light.

Explanation: Physical PROPERTIES: Physical properties can be OBSERVED or measured WITHOUT changing the composition of matter. Physical properties are used to observe and describe matter. Physical properties include: appearance, texture, color, odor, MELTING point, boiling point, density, SOLUBILITY, polarity, and many others

Rice CONSUMES about 4,000 - 5,000 litres of water per kg of grain produced. But it is no aquatic crop: it has great ABILITY to tolerate submergence. Water creates UNFAVOURABLE conditions for weeds, by cutting off sunlight and aeration to the GROUND. So, rice farmers ADOPTED the practice of submerging rice in water to check weeds.

er for ionic cycle :i. The constituent particles of ionic crystals are charged ions. The cations and anions may differ in size.ii. Each ion of a GIVEN sign of charge is bonded to ions of opposite charge around it by COULOMB force. In other words, the particles of ionic crystals are held by electrostatic force of attraction between oppositely charged ions.iii. Ionic crystals are hard and brittle. They have high MELTING points.iv. These are nonconductors of ELECTRICITYIN solid state. HOWEVER, they are good conductors when melted or dissolved in wate

tion:A gene mutation is a permanent alteration in the DNA sequence that makes up a gene, such that the sequence DIFFERS from what is found in most people. Mutations range in size; they can AFFECT anywhere from a single DNA building BLOCK (base pair) to a large SEGMENT of a chromosome that INCLUDES multiple genes.

the GIVEN function of VEINS:-Veins are an important part of our circulatory system.They are responsible for returning DEOXYGENATED blood back to the HEART after arteries carry blood out. The vena cava is the largest vein in the body. Veins have much thinner walls than arteries.

nsition ELEMENTS are metals and show properties that are characteristic of metals. They are hard, lustrous, malleable, ductile and form alloys with other metals. They are good conductors of heat and electricity. Except Zn, Cd, HG and Mn, all the other transition elements have one or more typical METALLIC structures at ambient temperature. These transition metals (with the exception of Zn, Cd and Hg) are very hard and have low volatility. They possess high melting and boiling POINTS.

re two types of POLLINATION, CALLED self-pollination and cross-pollination. Self-pollination is the more BASIC type of pollination because it only involves one flower. This type of pollination occurs when pollen grains from the anther fall DIRECTLY ONTO the stigma of the same flower.

Veins are the blood VESSELS that carry deoxygenated blood (blood that contains less OXYGEN, more CARBON dioxide and other metabolic wastes) from various parts of the body back to the heart and lungs for oxygenation. THANKS ❤️

radii of the elements of the transition SERIES decrease gradually from left to right. As we move across a transition series from left to right the nuclear charge increases by one unit at a time. The last filled electron enters a penultimate (n-1)d subshell. However, d orbitals in an ATOM are less penetrating or more diffused and, THEREFORE d electrons OFFER smaller screening effect. The RESULT is that effective nuclear charge also increases as the atomi number increases along a transition series. Hence the atomic radii decrease gradually across a transition series from left to right.

Angiosperm:- They are very large group of plants and occur in wide RANGE of habitats. Angiosperms are of two types-:(i) Monocotyledon:- Those which have only one COTYLEDON are known as Monocotyledon plants. Example:- Grass and cerals.(ii) Dicotyledons:- Those which have two cotyledons are known as Dicotyledon angiosperms. Example:- PULSESIN them anther and filament forms stamen or the male sex organ. After the process of meiosis pollen grains are FORMED in the anther. And then pollen grains are carried to the stigma with help of wind or with any other natural process. OVARY, stigma and style forms female sex organ in them.

isation ENTHALPIES of transition elements are INTERMEDIATE between those of s-block or p-block elements. This suggests that transition elements are less electropositive than elements of group 1 and 2. Depending on the conditions, they form ionic or covalent bonds. Generally in the lower oxidation STATES these elements form ionic COMPOUNDS while in the higher oxidation states they form covalent compounds

Solution : Here, F(X)=2X A function is a one-one function such that f(X1)=f(x2) only if x1=x2. Here, f(x1)=2x1 f(x2)=2X2 If f(x1)=f(x2), then, 2x1=2x2⇒x1=x2 ∴f(x) is one-one function. Now, for any value of x, we have a different value of f(x). That means, f(x) is onto function also.Explanation:
