Protein is the sequence of amino acids that could be translated from the sequence of mRNA.

Proteins are large macro- and biomolecules made up of one or more long chains of amino acid residues. Proteins play a variety of roles in living things, including catalysing metabolic reactions, reproducing DNA, responding to stimuli, providing cells and organisms structure, and transporting chemicals.

The order of a protein's amino acids, which is dictated by the nucleotide sequence of its genes and normally enables a protein to fold into a certain 3D structure that regulates its function, is the main way that proteins differ from one another.

Various methods, including ultracentrifugation, precipitation, electrophoresis, and chromatography, can be used to separate proteins from other biological components. The development of genetic engineering has made several purification procedures possible. Immunohistochemistry, site-directed mutagenesis, X-ray crystallography, nuclear magnetic resonance, and mass spectrometry are techniques that are frequently used to research protein structure and function.

When calcium ions enter the synaptic terminal neurotransmitter molecules are quickly removed from the synaptic cleft.

Neurotransmitter molecules are swiftly cleared from the synaptic cleft when calcium ions enter the synaptic terminal. They lead to the plasma membrane of the transmitting neuron's neurotransmitter-carrying vesicles fusing together. As a result, the sending neuron experiences an action potential.

Presynaptic and postsynaptic terminals make form a synapse. The presynaptic terminal, which lies at the end of an axon, converts the electrical action potential into a chemical signal (neurotransmitter release).

The synaptic terminal, also known as the axon terminal, is where the axon terminates. Here, a chemical signal known as a neurotransmitter transforms an electrical signal that was originally sent electrically. In order to enhance communication with neighbouring cells, neurotransmitters are released into the synapse.

Lymphatic cells are an essential part of the body’s immune system. Each type of lymphatic cell has a unique function, from detecting and destroying foreign invaders to forming the blood-thymus barrier.

The first type of lymphatic cell is the Natural Killer (NK) cell. NK cells are a type of white blood cell that is able to detect and destroy cells that are infected with viruses or otherwise damaged. NK cells are particularly important when it comes to preventing the body from rejecting a kidney transplant, as they can detect and destroy cells that the body would otherwise reject.

The second type of lymphatic cell is the Antigen Presenting Cell (APC). APCs are cells that are able to detect and present antigens to the body. They are able to detect foreign invaders, such as bacteria, and present them to other immune cells, such as T cells and B cells, which can then mount an immune response.

The third type of lymphatic cell is the T cell. T cells are able to recognize and bind to antigens that have been presented to them by APCs. They can then alert the body of the presence of foreign invaders, and initiate an immune response to destroy them.

The fourth type of lymphatic cell is the B cell. B cells are able to ingest and destroy bacteria, viruses, and other foreign invaders. They can also secrete antibodies, which can help to neutralize the invaders and prevent them from causing further harm.

The fifth type of lymphatic cell is the thymus-derived lymphocyte. Thymus-derived lymphocytes form the blood-thymus barrier, which helps to protect the body from bacteria, viruses, and other foreign invaders. They are able to detect and recognize foreign invaders, and alert the body of their presence.

We may face many problems without the presence of coral reefs. These are-

1)Less Fish in the Ocean-Coral reefs are said as “the rainforests of the sea” and give a quarter of marine species with habitat and food. If coral reefs vanished, essential food, shelter, and spawning grounds for fish and other marine organisms would cease to exist, and biodiversity would greatly suffer. Marine food webs would be altered, and many economically important species would vanish.

2) No More Tourists -Coral reefs also sustain smaller economies through tourism and attract tourists to over 100 countries. Without reefs to visit, there will be a reduction in tourist numbers, which will have a knock-on effect on local businesses that depend on year-round tourists.

3)Losing Our Coastlines -The most important impact that would occur if coral reefs were to vanish, is the negative impact on coastlines. Shorelines will become battered by waves and extreme weather events, and become unsafe to erosion. Erosion of the coastline, combined with sea-level rise due to climate change, will push coastal communities from their homes and further inland.

The density of mercury is greater and the mercury neither wets nor sticks to the glass tube therefore, it gives the correct reading. hence, mercury is used in barometer.

The barometer works by balancing the weight of mercury in the glass tube against the atmospheric pressure. if weight of mercury is less than the atmospheric pressure, the mercury level in the glass tube rises (high pressure). If it's more than atmospheric pressure, the mercury level falls (low pressure). Although, other liquids can be used in barometer, mercury is the common one. The density of mercury allows the vertical column of the barometer to be of manageable size. Using mercury in barometer is advantageous as its density is high it has low vapour pressure; its rate of evaporation is not very high. Mercury barometer is precise and offers a simple method of measuring the atmospheric pressure. Mercury is inexpensive and does not require any expensive equipment to be made.
