Define the term isotope?

Any of two or more forms of a chemical element, having the same number of protons in the nucleus, or the same atomic number, but having different numbers of neutrons in the nucleus, or different atomic weights.

What is the definition of constant variable?

The definition of constant variable is a variable whose value cannot be changed once it has been assigned a value for an experiment. It is the variable held steady, or constant, for a specific experiment.

How many non bonding electrons does carbon have?

The electrons out of ionic bonds and covalent bonds are called as non bonding electrons. Valence electrons are the bonding electrons of carbon.

What state matter has particles flying about wildly?

In a gas state, particles move freely and rapidly in random directions due to their high kinetic energy. This results in a lack of fixed shape or volume, as the particles are constantly colliding and spreading out to fill the container they are in.

Methane gas [CH4---"natural gas"], Hydrogen Sulphide [H2s], Sulphur Dioxide, Sulphuric Acid, Ammonium Hydroxide, Ammonia, some limited amount of "compost" from vegetation, oxides of various metals, and a variety of salts resulting from the combination of some of the above products.

How to help someone get over an ex?

You're really a very good friend or possibly a prospect at a later date regarding a relationship with this person. Whatever, it's nice you care enough. Unfortunately, when there is a painful breakup it's much like grieving over the loss of a loved one that has died. In ways the ex that was in your friend's life has died. They no longer are part of them. It takes time and patience, but trust me when I say that in time they will get over it, meet someone else and all will be well again for them. Just hang in there and listen or take them out for a bit of fun. They may sit there looking sad and disinterested for awhile, but eventually they will come around and be their old self again.

What is cellular metabolism?

Cellular metabolism refers to the various chemical reactions that take place in cells to produce energy and biomass. These reactions involve breaking down nutrients to obtain energy (catabolism) and building molecules necessary for cell function (anabolism). Cellular metabolism is essential for maintaining life and carrying out various cellular processes.

What is a lipid?

Lipids are a diverse group of molecules that include fats, oils, triglycerides, phospholipids, and cholesterol. They are essential components of cell membranes, energy storage, and signaling molecules in the body. Lipids are non-polar and insoluble in water.

Convert Fisher projection to Haworth structures?

Groups on the left side goes up (left high and dry)... groups on the right side go down (be right down). It's pretty much that simple Groups on the left side goes up (left high and dry)... groups on the right side go down (be right down). It's pretty much that simple

What are lipids?

lipids are a broad group of naturally occurring molecules which includes fats, waxes, sterols, fat-soluble vitamins (such as vitamins A, D, E and K), monoglycerides, diglycerides, phospholipids, and others. The main biological functions of lipids include energy storage, as structural components of cell membranes, and as important signaling molecules.

simple answer: lipids are energy-rich compounds made of carbon, oxygen, and hydrogen. Lipids are organic molecules that contain hydrogen and carbon and are crucial for cell growth.

What is the normality formula?

The formula for normality is number of equalants over liters of solution. Example if the questions gives you 86g of H2SO4 WITH A VOLUME OF 22 L and what is its NORMALITY? This is how You start the question. First H2SO4 is a acid not a base it contains H+ ions.

So 1 mol of H2SO4 - 2 mols of H+

your probaly wondering why this 2 mols of H+ because next to the H theres a 2

you never want 2 mols H+ you have to get one

so you u cut it in half (note it can never have more than one mole so you have to half it or if its 3 you have to make it to 1 third or 4 1 forth)

Next you go half mol of H2SO4 - 1 mole of H+

Then after you go One EQUALANT - 1 half mol of H2SO4

Then EQUALANT WEIGHT - HALF the molar mass (but note its not always half just because you have two moles. this goes for the same at the top if the moles are 3 then you multiply the molar mass by 1 third)

after the 4 steps you make the equalant weight equal to the molar mass

then after u get a mass

then you put the mass from the question you divide it with the mass u just got from the top

you get a anwer after you get the answer in EQUALANT

THEN AFTER U GOT YOUR EQUALANT YOU PLUG IN INTO THE FORMULA NORMALITY = EQ OVER LITERS

Why carnitine deficiency causes impaired gluconeogenesis?

Carnitine deficiency can impair gluconeogenesis because carnitine is necessary for the transport of fatty acids into the mitochondria for beta-oxidation. Without adequate carnitine, there is a buildup of fatty acids in the cytoplasm, leading to an imbalance of acetyl-CoA, which can inhibit gluconeogenesis. This can result in decreased glucose production and energy production in the liver.

What part of the enzyme gives each enzyme its unique function?

i think it's the shape of the active site, the region where the enzyme comes into direct contact with the substrate. the shape of the active site is in turn determined by the structure of the enzyme, which is determined by the number and sequence of amino acids in the primary strucutre.(note that pH affects the shape of the active site as well.) just my guess.

How is nitrogen fixation carried out?

Nitrogen fixation is the process by which nitrogen is taken from its relatively inert molecular form (N2) in the atmosphere and converted into nitrogen compounds useful for other chemical processes (such as, notably, ammonia, nitrate and nitrogen dioxide).

What is protein estimation?

here the amount of protein in a sample can be determined, using different protocols, wherein the reagent mixture( ex: FC reagent) which when added to the sample containing protein reacts with the specific amino acids giving colour, thus the amount of protein in a sample can be estimated and the data used for further protein studies.

Which is the fastest moving hormone in human body?

Epinephrine, also known as adrenaline, is considered one of the fastest-acting hormones in the human body. It is released quickly in response to stress or danger, allowing the body to prepare for the “fight or flight” response by increasing heart rate, dilating airways, and directing blood flow to essential muscles.

What vitamin deficiency causes light headedness?

There a lots of things that you could be lacking in your diet, but it would be advisable to take a daily vitamin. Try not to take the synthetic vitamins though. Try and get herbal ones as much as you can as they are easier for the body to digest, they are more effective, and a lot safer.

Here are some reasons why one could be light-headed: * Not eating properly (skipping meals) Our bodies need fuel like anything else in order to work properly. * High blood pressure. * Some medications you could be taking. (read side effects of medication) ALWAYS get a print-out on your medications from the pharmacist. * Inner ear problem. It is wise to see your doctor before counting on just vitamins. Vitamins are good for you, but will do little if you aren't eating properly.

Why RNA-primer only initiates replication?

Laxu's answer made no sense so I deleted it. Next time Laxu please contribute something that makes some grain of sense.

Only RNA primers can be used because DNA polymerase cannot add nucleotides without an existing 3-OH' to build on. RNA can be added to an existing template without this requirement and is then used by the DNA polymerase to initiate the strand.

Is milk a suspension solution or colloid why?

Milk is a suspension for all of its particles are not completely dissolved within the liquid. If you could observe milk up close, you could see particles floating around in the liquid. A suspension is defined a a liquid with solids dispersed throughout it and milk fits this definition.
