Why does DNA replication have such accuracy ?

Answers

Answer 1
Answer: Because human DNA is so very long (with up to 80 million base pairs in a chromosome) it unzips at multiple places along its length so that the replication process is going on simultaneously and more accurately.

Consider the following events of photosynthesis. 1. Light energy excites electrons. 2. Water molecules are split. 3. NADPH is formed. In which locations do each of these events occur? 1. photosystem II 2. photosystem I 3. photosystem I 1. photosystem II 2. photosystem II 3. photosystem I 1. photosystem I 2. photosystem I 3. photosystem II 1. photosystem I 2. photosystem II 3. photosystem II

Answers

Answer: Option B. 1. photosystem II 2. photosystem II 3. photosystem I

Explanation:

Photosynthesis is the process by which plants make their own food in the presence of light utilizing carbon dioxide and water. this process occurs in chloroplast which contains green pigments called chlorophyll.

Photosystem are defined as the cluster of chlorophyll pigments found on the thylakoid membrane ( in chloroplast) which functions to collect energy and concentrate it to reaction center which further uses the energy to excite electrons and pass on to enzymes.

Photosystem II absorbs light and energy which allows the excitation of electrons and creates an electron deficiency in Photosystem II. the deficiency filled by Z protein which contain manganese that stimulates splitting of two water molecules.

NADPH formation takes place in Photosystem I. Photosystem I accepts energy from light which excites an electron and passed on to an electron acceptor called FeS.  FeS then passes its e- to Ferrodoxin which donates its electron to NADP+ reductase. NADP+ reductase donates electron to NADP+ and add a proton  to form NADPH to get stabilized.

Hence, the correct option is B.

B

Which is an appropriate justification for this the roots of the aquatic plant hydrilla are poorly developed and lack xylem tissue.

Answers

The most appropriate justification for the roots of the aquatic plant hydrilla to be poorly developed and lack xylem tissue is to reduce the intake of water to the plant. Therefor the best answer choice is…


C) As hydrilla is aquatic in nature, the roots do not have to search for water, and there is no need for xylem to absorb water because the plant is surrounded by water.
