"Complex Carbohydrates" are l<span>iving organisms break down polysaccharides into simple sugars. Complex carbohydrates are made up of sugar molecules. They are like strings that is long and complex chains. They can be found on foods like beans, whole grains, vegetables, and peas. They are converted into glucose in the body which serves as the source of energy of the body.</span>
<span>The discoverers of DNA were not James
D Watson and Francis Crick. They are the first scientist to formulate an
accurate description of the DNA’s (deoxyribonucleic acid) complex ,
double-helical structure. They discovered that base pairing nucleotides must
be; adenine and thymine; and cytosine and guanine. These base pairs are held
together by a hydrogen bond, atype of chemical reaction that s easy to break
and easy to reform. The statement is “DNA
is a double helix made of two strands linked together with hydrogen
bonds.”</span>
Answer:
The given steps are of light phase of photsynthesis.
1)A photon of light excites photosystem II.
2)A water molecule is split, the electrons are transferred to photosystem II.
3)Oxygen is formed as an endproduct.
4)An electron is transferred from photosystem II to the primary electron acceptor.
5)ATP is synthesized as the electrons pass through an electron transport chain to photosystem I.
6)A photon of light strikes photosystem I, an excited electron is transferred to the primary electron acceptor.
7) An electron is transfered from an electron transport chain from photosystem II to photosystem I's primary electron acceptor.
8)Electrons are passed from photosystem I through an electron transport chain.
9)NADP+ is reduced to NADPH.
Explanation:
Please look in the attached file for diagrammatic explanation.
The correct answer is option A, " Energy production"
Reason:
The intracellular communication is the process through which one cell interacts with other cell for proper functioning of the body. The two major types of intracellular interaction involve:
a) Chemical Synapse – In this a chemical released by one cell is detected by receptor on another cell. For example the transmission of sodium and potassium ion across the membrane through the binding of Acetylcholine (Ach) with ACh receptors.
b) Electrical Synapse – In this the cell which are connected through non selective, low – resistance pore between pre- and postsynaptic neurons known as gap junction.
This is the case in option B, C and D.
