Second stage of cellular respiration is
The stage happens in mitochondria.
Oxygen combines with small molecules.
Energy is released.
<u>Explanation:</u>
Krebs cycle is the another name for second stage of cellular respiration . Throughout this stage, pair of molecules of ATP are generated. Another energy-storing molecules are also produced. Into the mitochondrial matrix which is the deepest part of mitochondria, all pyruvate from glycolysis (from first stage) moves.
The Krebs cycle lacks oxygen. Anything that requires oxygen is represented as aerobic. The oxygen blends with the carbon from the pyruvate molecules. This creates carbon dioxide, a waste product. As a result of second stage NADH is generated.
Answer:
When you are hungry your brain signals your digestive system to prepare for food. This leads to stomach growling. Your brain does this because it knows that you are hungry, and consequently the brain signals the digestive muscles to contract. There is also, usually, some gas in the intestines and stomach. The noises come out when the mixture of the gas and fluid, digestive juices, squirt through a opening that separates the stomach and small intestine.
Sometimes the noises happen because of an excessive amount of gas in the small intestine.

also searching up forums is also a great thing
even study guides could help alot
Answer:
A. Science cannot answer philosophical questions.
Explanation:
Because at least some philosophical problems are not real problems. Instead of a language disease, the solution is not solved by scientific means, but by standardizing the use of language and slenderness. For people who are obsessed with philosophical questions, no scientific explanation can convince them.
Proteins are made using DNA as a template. The DNA is turned into RNA, and the RNA is then turned into DNA.
<span>The sequence of nucleotides is like the letters in a recipe book. They say what protein is made. So, a change in the nucleotides makes a change in the protein. Sometimes that does nothing; sometimes it causes a malfunction. It just depends on how important that section of the protein is. </span>
<span>A change in these nucleotides could end up making some part of the protein different. A single nucleotide change could be silent (no change in the protein) or could change a single amino acid (amino acids are the building blocks of proteins). If that was an important amino acid, the protein might not function at all! A silent change can occur because the same set of nucleotides sometimes makes the same final amino acid (for example, reading "gcc" "gca" "gcg" or "gct" nucleotides all mean "alanine" amino acid). </span>
<span>The deletion of a single nucleotide, or the addition of one, can change the entire sequence of amino acids that come after it! Nucleotides are read in sets of three, so this throws off how the DNA is read. If would be like turning "The brown fox jumps over the dog" into "The gbrow nfo xjump sove rth edo g". Completely different! All of the words are thrown off.</span>
