Answer:
2 molecules of ATP and 2 molecules of NADH
Explanation:
Glycolysis is the first step of cellular respiration (break down of glucose to extract energy) which occurs in the cytoplasm. Glycolysis is a pathway common to all living organisms- prokaryotes and eukaryotes, as it does not require oxygen to occur.
Glycolysis occurs in two major phases (ten steps) requiring 10 enzymes catalyzing each step; the energy-requiring phase and the energy-requiring phase.
In the energy-requiring phase, the starting molecule (glucose) gets rearranged in a series of chemical reactions, and two phosphate groups gets attached to it producing fructose-1,6-bisphosphate which is unstable, This modified sugar then splits in half due to its instability to form two different but inter-convertible phosphate-bearing three-carbon sugars (Dihydroxyacetonephosphate, DHAP and Glyceraldehyde-3-phosphate, G3P). Because the phosphates used in these steps come from 2 ATP molecules, 2 ATP molecules get used up in this phase
All the DHAP molecules get converted to G-3-P in order to enter the next phase.
In the energy-recovering phase, the 3-carbon sugar (G3P) is converted into another three-carbon molecule called pyruvate, through a series of reactions. In these reactions, two ATP and 1 NADH molecules are made. This recovery phase occurs twice (one for each of the two isomeric three-carbon sugars, DHAP and G3P). Hence, a total of 4 ATP and 2 NADH molecules are produced in this phase.
Overall, Glycolysis converts one glucose (six-carbon) molecule to two pyruvate (three-carbon) molecules and a net release of 2 ATP molecules (4 overall - 2 used) and 2 NADH molecules.
Omnivores and carnivores are related because omnivores also eat meat and carnivores eat strictly meat. For example, a t-rex is a carnivore and a omnivore is those rhino looking dinosaurs.

Answer:
Asexual Reproduction: Mitosis, genetic sameness
Sexual Reproduction: Meiosis, produces gametes, genetic variation,
Both: Nuclear Division, DNA replicated
Not too sure about the DNA replication but i hope this helps !
iconic bond -> sharing of many electrons
metallic bond -> sharing of electrons
covalent -> transferring of electrons
hope this helps...
Cryogens and dry ice are cryogenic substances that cause skin related problems if not handled carefully. These are extremely dangerous to touch and cause boiling of skin. The skin is severely damages if touched with naked hands.
Care should be taken while handling cryogens Use of specific gloves and personal protective equipments to cover yourself.
Answer: FALSE
