Answer; All the above
A) an atom seeks to fill its outer shell of electrons
B) an atom seeks to balance its positive and negative charges
C) the reaction will result in paired electrons
Explanation;
-In a chemical reaction, reactants contact each other, bonds between atoms in the reactants are broken, and atoms rearrange and form new bonds to make the products.
-During a chemical reaction an atom may lose of gain electrons resulting positive and negative ions (ionic bond formation) or may result to the paired electrons (sharing of electrons).
Answer:
Other species that rely on those fish would die off. The extinction of one species can lead to the extinction of another and so on.
Answer:
a. Mastication process and formation of bolus in the oral cavity
b. The contraction in the stomach breaks the food down into smaller pieces. These pieces are then moved to the small intestine.
c. In the small intestine, food particles are broken down into nutrients, fat, protein and carbohydrates which are absorbed into the bloodstream.
Explanation:
a. First step of digestive system functioning is the mastication process and formation of bolus in the oral cavity.
b. The contraction in stomach, with the help of digestive enzymes and acids, break the food down into smaller pieces. The small pieces of food are then released into the first part of the small intestine (duodenum).
c. In the small intestine, two enzymes released from pancreas and gall bladder break down the food particles into fats, proteins, and carbohydrates. Thereon, nutrients and carbohydrates, proteins and fats are absorbed into the bloodstream.
Answer:
Sympathetic nervous system
Explanation:
The sympathetic nervous system is the part of the autonomic system of neurons which gets activated in the condition of stress.
The stress conditions activate the sympathetic nervous system which prepares the human body for the stress condition by either fight or flight mode.
The fight or flight responses requires a large amount of energy which are produced by the activation of the parasympathetic energy therefore the sympathetic system involves the expenditure of the energy. The system is also involved in sexual arousal.
Thus, the Sympathetic nervous system is the correct answer.
For B. It is CAC
For the rest there needs to be a codon table for us to see
