What are the methods of waste disposal ? Write in briefly.
Answer:
Methods of waste disposal are :-
Biogas plant: - Biodegradable material is used to produce biogas and manure.
Sewage treatment plant: The drain water is treated at plants before adding it to river.
Land filings: - The waste are buried in low-lying areas and compacted with bulldozers.
Composting: - Organic waste are filled in compost pit to make compost for plants.
Recycle: - This means that you collect plastic, paper, glass and metal items and recycle these materials to make required things instead of synthesizing or extracting fresh plastic, paper, glass or metal. In order to recycle, we first need to segregate our wastes so that the material that can be recycled is not dumped along with other wastes.
Reuse: - This is actually even better than recycling because the process of recycling uses some energy. In the ‘reuse’ strategy, you simply use things again and again. Instead of throwing away used envelopes, you can reverse it and use it again. The plastic bottles in which you buy various food-items like jam or pickle can be used for storing things in the kitchen.
Refuse: -This means to say No to things people offer you that you do not need. Refuse to buy products that can harm you and the environment, say No to single-use plastic carry bags.
Repurpose - This means when a product can no more be used for the original purpose, think carefully and use it for some other useful purpose. For example, cracked crockery, or cups with broken handles can be used to grow small plants and as feeding vessels for birds.

Answer:
flexion
Explanation:
The flexion is a movement of the body part that is described the bending of an elbow, or the clenching a hand into a fist, etc. where the angle between any segment of the body and its proximal segment decreases.
In simple words, the flexion is a movement which decreases the angle between two body parts when they are moved.
The flexion occurs in the sagittal plane.
Thus, the movement of a thumb that would be mostly affected by the lesion of median nerve in cubital fossa is the flexion movement.

From deep to superficial, the order of the strata of the epidermis is corneum - granulosum - lucidum - spinosum - basale. spinosum - granulosum - basale - lucidum - corneum. basale - granulosum - spinosum - lucidum - corneum. corneum - lucidum - granulosum - spinosum - basale. basale - spinosum - granulosum - lucidum - corneum.
Answer:
basale - spinosum - granulosum - lucidum - corneum.
Explanation:
The order of strata in the epidermis:
Basale: it is the deepest stratum. It has one layer of cells called keratinocytes, which are stem cells for the epidermis.Spinosum: The keratinocytes in this layer have spiny shapes. They synthesize cytokeratin and lipids. In this layer, we can also find macrophages.Granulosum: The keratinocytes of the previous layer ascend and synthesize keratohyalin, which is in granules. The keratohyalin helps to join keratin filaments. Also, the cells release the lipids synthesized in the previous layer, and they form a barrier that stops dehydration.Lucidum: it is only on thick skin, like the one in the sole of the feet. The keratinocytes in this layer have expelled the nucleus and now are dead cells. The keratinocytes have a flat shape and form a thin layer.Corneum: it is the most superficial layer. It is made of dead keratinocytes filled with keratin in their cytoplasm. It is a thick layer that suffers desquamation when new dead cells filled with keratin ascend from the previous layer.The Venn diagram compares aerobic respiration and anaerobic respiration.

When there is plenty of oxygen available in the muscles, the condition is referred to as being:
Answer:
Aerobic condition.
Explanation:
When there is plenty of oxygen available in the muscles, the condition is referred as aerobic condition because the muscles do respiration in the presence of oxygen. The presence of oxygen to the muscles produced huge amount of ATP which can be used by the body in different activities as compared to anaerobic condition where there is no oxygen and the body produce less ATP for the body.

Just after they taste a sweet liquid, mice are injected with a drug that produces an immune response. Later, the taste of the sweet liquid by itself triggers an immune response. This best illustrates
Answer:
This question lacks options, options are:
a) classical conditioning
b) observational learning
c) spontaneous recovery
d) operant conditioning.
The correct answer is a.
Explanation:
The classical conditioning theory derives from the experiments of the Russian physiologist Ivan Pavlov, he hypothesized that when any stimulus predicts the occurrence of another stimulus that triggers an automatic response, that first stimulus would acquire the ability to trigger that response, in other words , is a type of learning according to which an originally neutral stimulus, which does not provoke a response, becomes able to provoke it thanks to the associative connection of this stimulus with the stimulus that normally provokes said response. The conditioning of the immune response is built on the same principles of the classical conditioning paradigm described by Ivan P. Pavlov in which an environmental stimulus that by itself does not produce any immune reaction (conditioned stimulus), is associated with substances that stimulate or they suppress immune function (unconditioned stimulus), and finally, by presenting the conditioned stimulus alone, trigger the appropriate immune response.
Autoclaving is the most effective among all moist heat-related antimicrobial methods. (True or False)
Answer:
True.
Explanation:
Autoclaving is the most effective among all moist heat-related antimicrobial methods because this method can kill all the harmful microbes such as bacteria, fungi and viruses. Moist heat causes destruction of microorganisms by denaturation of macromolecules that is present in their body such as proteins. Autoclaving is a very common method for moist sterilization. It is an effective method in killing fungi, bacteria, spores, and viruses but it does not eliminate prions.

When one expects something and gets something else, then one is having a big enough cause to ask for new questions and initiate a new investigation. Scientific investigation is the process by which the researchers and scientists use a planned approach to answer questions regarding the world around us.
