No,it doesn't PERFORM PHOTOSYNTHESIS. THANKS me and MARK me as BRAINLIST.

tion:HYENAS are a specialized type of carnivore called a SCAVENGER. SCAVENGERS consume the bodies of animals the scavenger did not KILL.

Yes the heterotrophs do not PERFORM PHOTOSYNTHESIS because they depend on OTHERS for food as this process is CARRIED away by the plants and they are autotrophs.

orrectExplanation:like in papaya FLOWER only male or female organ present.thanks for ASKING questions.please TAPE thanks and STAR button.

ogy, abiotic factors can INCLUDE water, light, radiation, TEMPERATURE, humidity, ATMOSPHERE, ACIDITY, and soil. The macroscopic climate often influences each of the above. Pressure and sound waves may also be considered in the context of marine or sub-terrestrial environments.mark me as BRAINLIEST

tion:1.The cell membrane is a BIOLOGICAL membrane that SEPARATES the interior of all cells from the outside environment which protects the cell from its environment. The cell membrane consists of a lipid bilayer, including cholesterols that sit between phospholipids to maintain their fluidity at various temperatures. 2. nucleus is the central of cell which controls the cell3.Ribosomes4.DNA, SHORT for deoxyribonucleic acid, is the molecule that contains the genetic code of organisms. This includes animals, plants, PROTISTS, archaea and bacteria. DNA is in each cell in the organism and tells cells what PROTEINS to make. Mostly, these proteins are enzymes.4.Vesicles and lysosomes

Characteristics. All coelenterates are aquatic, mostly marine. The bodyform is RADIALLY symmetrical, diploblastic and does not have a coelom. The body has a single OPENING, the HYPOSTOME, SURROUNDED by SENSORY tentacles equipped with either nematocysts or colloblasts to capture mostly planktonic prey.

opagation (also called PLANT tissue CULTURE) is a method of propagating a large number of plants from a single plant in a short time under laboratory CONDITIONS. ... To start plant tissue culture, a part of the plant such as a stem, leaf, embryo, anther, or SEED can be used.mark me as brainliest

There are several DIFFERENT METHODS of ASEXUAL REPRODUCTION. They include binary fission, fragmentation, and budding. Binary fission occurs when a parent cell splits into two IDENTICAL daughter cells of the same size

tion:The cell wall surrounds the plasma membrane of plant cells and PROVIDES tensile strength and protection against mechanical and osmotic stress. It also allows cells to develop TURGOR pressure, which is the pressure of the cell contents against the cell wall.hope it will HELP U ✌️

Nitrogen is so vital because it is a major component of chlorophyll, the compound by which PLANTS USE SUNLIGHT energy to produce sugars from water and carbon dioxide (i.e., PHOTOSYNTHESIS). It is also a major component of amino acids, the BUILDING blocks of proteins. Without proteins, plants wither and die.

Trees are a PART and parcel of earthly life. All life directly or indirectly OWES its EXISTENCE to them. Trees RELEASE OXYGEN which we need for our life. They also absorb the carbon-dioxide.

Here is the answer:EXPLANATION:Virtual MEANS not real or something that doesn't exist in nature. Virtual is also an EXPERIENCE of something which is not GENUINE like VR gaming ETC.

yesExplanation:Modern HUMANS coexisted with woolly mammoths during the Upper Palaeolithic PERIOD when the humans ENTERED Europe from AFRICA between 30,000 and 40,000 years AGO.

The WORD 'ANTIBIOTICS' was first USED over 30 years later by the Ukrainian-American inventor and microbiologist Selman Waksman, who in his lifetime discovered over 20 antibiotics. Alexander Fleming was, it seems, a BIT disorderly in his work and accidentally discovered PENICILLIN.

Though it's TINY in size, it performs all the life functions. And it's due to cells our whole BODY mechanism works. Cells TOGETHER join to form tissues, tissues together join to form organs, and then organ SYSTEM. That's how a small tiny cell works.Please mark brainliest if it helped ya :)

y amylase INITIATES STARCH hydrolysis in the mouth, and this process accounts for not more than 30% of total starch hydrolysis. Because SALIVARY amylase is inactivated by an acid pH, no significant hydrolysis of carbohydrates OCCURS in the stomach.

One of the few outward CONTRASTS between Rafflesia and Sapria, Davis said, is the number of lobes — Sapria has 10 or more, Rafflesia just five. A closer look, HOWEVER, REVEALED vast differences in structures that APPEAR very similar.Explanation: PLEASE mark as brainlist .

Keynotes for Chapter - Why Do We Fall Ill, are: Health Health is a state of complete physical, mental and social wellbeing. Disease Any disturbance in the structure or function of any organ or part of body. It may be caused due to the attack of pathogens (virus, bacteria), lack of nutritious DIET/balanced diet and lack of public health services. CBSE Class 9 Science Syllabus 2020-2021 Types of Disease Diseases are basically of two types. They are: (i) Acute Disease The disease which lasts for only a short period of time is called Acute Disease. For example: Influenza (Flu), Common cold, etc. (ii) Chronic Disease: The disease which lasts for a long period of time is called Chronic Disease For example: TB, Cancer, etc. Difference between Acute Disease & Chronic Disease S. No. Acute Disease Chronic Disease   1. They are short duration diseases. They are long lasting diseases. 2. Patient recovers completely after the cure. Patient does not recover completely. 3. There is no loss of weight or feeling of tiredness afterward. There is often loss of weight of feeling of tiredness. 4. There is short-duration loss of work and efficiency. There is a prolonged loss of work and efficiency. Causes of Diseases:   Causes of diseases are EXPLAINED below: Immediate and Contributory Cause Immediate cause: The organisms that enter our body and cause the disease are termed as an immediate cause. For example, virus, bacteria, protozoa etc. Contributory cause: The secondary factors which led these organisms enter our body are termed as a contributory cause. For example, dirty water, contaminated food, improper nourishment, poor standard of living, etc. Infectious and Non-infectious Cause Infectious causes: They include the agents like microbes or micro-organisms as the immediate causes which spread the disease from an infected person to a healthy person. Non-infectious causes: The disease which does not spread by contact between infected and healthy person through air and water, is called non-infectious disease. Infectious and Non-infectious Diseases Infectious Diseases: The diseases which spread due to infection by micro-organisms are called infectious diseases. When a disease causing organism enters our body it causes infection, it multiplies and grows in the body called host and micro-organisms multiplies in the host body. For example: Tuberculosis, tetanus, Common cold, AIDS, etc. Non-infectious Diseases: The disease which does not spread by contact between infected and healthy person through air and water, is called non-infectious disease. For example: Cancer, genetic abnormalities, high blood pressure, etc. Means of Spreading Infectious Diseases: S. No. Type of Disease Example 1. Air born Diseases Common cold, influenza, measles, tuberculosis. 2. Water born diseases Cholera, typhoid, hepatitis. 3. Sexual Diseases AIDS, Syphilis. 4. Animal born Disease Rabbis. Antibiotics These are the chemicals (medicine, drugs) that block biochemical pathways important for bacteria. They are used for diseases caused by bacteria. Antibiotics do not work against viral infections as the viruses do not have their own biochemical mechanisms but depend upon that of the host. Principles of treatment 1. To reduce the effects of the diseases By taking medicines to bring down the effects of the disease like fever, pain, etc. and by taking complete rest to conserve the body’s energy. 2. To kill the cause of the disease By taking suitable antibiotics and drugs which kill the disease causing microbes. Principles of Prevention 1. General method: They involve (a) Preventing exposure against microbes (b) By boosting the immune system (a) Preventing exposure against microbes can be done in the FOLLOWING ways: For air-born microbes we can prevent exposure by avoiding overcrowded places. For water-borne microbes we can prevent exposure by not using contaminated water. For vector-borne infections we can prevent exposure by providing a clean environment. (b) By boosting the immune system: Our immune system plays an important role in fighting against the microbes that enter our body. strengthening the immune system can help in preventing many diseases.   So, proper nourishment or healthy diet that includes all the necessary nutrients as well as vitamins and minerals is necessary for better functioning of our immune system. 2. Specific method It INVOLVES the prevention method DIRECTED against a particular disease. It is done by immunisation which is the process of introducing a weakened pathogen inside the body of the host to make his/her immune system to produce antibodies against that particular disease so that the next time even if the disease will strike the host’s body with full vigor, the body will be able to protect itself with the help of these antibodies.

(1) as they do not GET AIR for germination(2)as the germination process requires water(3) as they are not present in DORMANT STAGE and are in the growth stageExplanation:

A porous SOIL is made from coarse particles that leave large gaps known as PORES. The spaces between the particles of clay, SILT and SAND that make up the structure of your soil hold air and water. These pores also facilitate the movement of air and water through the soil.Explanation:PLEASE follow me

The advantage of the globe is that it promotes VISUAL accuracy. Students need to use a globe FREQUENTLY if they are to form accurate mental maps. The advantage of the WORLD map is that you can SEE the entire world at one time.

Hello BRO please clearly write the QUESTION FIRST OK

duct of (-124)×(-3)×(120) is (-124)×(-3)×(120)(372)×(120)→ 44,640Hope this HELPS you dear

h of the following does not have a nucleus?☑ a)red blood cellsb) white blood cellsc)guard CELLD) epidermal cell Mature red blood corpuscle does not have a nucleus. They are lack of nucleus and most of the cell organelles. They do not have cell organelles such as Endoplacmic Reticulum, Golgi body and mitochondria. They have LARGER amount of diffusion pigment called haemoglobin. They blood is a red coloured fluid connective tissue. The 55% of blood consists PLASMA and the rest of 45% of blood consists Blood corpuscle. The Red blood cells transports oxygen to all the tissues of the body for respiration process. Blood also MAINTAINS the regulation of pH and body temperature. White blood cells engulfs the disease causing MICROORGANISM and provide protection to our body. Platelets prevent the loss of blood in our body when we get injured.
