Answer:

The correct answer is option D.

Explanation:

A gene or genetic mutation is a permanent alteration in the sequence of DNA that makes up a gene. It can affect individuals in two ways in body cells by gametic cells that may transfer to offspring and somatic cells are only affect the individual but not passes on to offspring.

Somatic or body cell mutations occur during a person's lifetime and are occur only in certain cells in the body.

Thus, the correct answer is option D.

Describe the process of light-independent
xxTIMURxx [149]

Explanation:

  1. Light energy is absorbed and transferred to the reaction center.
  2. A water molecule is split.
  3. Electrons are transferred from photosystem II to photosystem I.
  4. ATP is synthesized from ADP and inorganic phosphate.

Output: ATP, NADPH, O2

Further Explanation:

Photosynthesis is a chemical pathway that’s integral to producing energy in plants and other primary producers. Energy in the form of molecules of glucose is produced from light, water and carbon dioxide while oxygen is released. This occurs in several complex steps, photosynthesis is a rate limited reaction, depends on several factors including carbon dioxide concentration, ambient temperature and light intensity; the energy is retrieved from photons, I.e. particles of light, and water is used as a reducing agent. This occurs in the thykaloids, where pigment molecules like chlorophyll reside.

The chloroplast is a membrane bound organelle found in plants. It contains several invaginations of a plasma membrane called the thylakoid membrane. This contains chlorophyll pigments, in stacks called granum, while the internal spaces of the organelle are called the lumen. Liquid surrounds the granum, forming the stroma.

During the light reaction:

  • Light is absorbed by pigments in phosystem II (PSII). This energy is transferred among pigments til it gets to the reaction center, and is transferred to P680; this promotes an electron to a higher energy level where it then goes to an acceptor molecule.
  • Water supplies the chlorophyll in plant cell with replacement electrons for the ones removed from photosystem II. Additionally, water (H2O) split by light during photolysis into H+ and OH- acts as a source of oxygen along with functioning as a reducing agent.
  • the electron moves down an electron transport chain (to PS I)where it experiences continuous energy loss. This energy fuels the pumping of H+ from the stroma to thykaloid, leading to the formation of a gradient. The H+ move along their gradient and cross through ATP synthase, into the the stroma.
  • ATP synthase converts ADP and Pi to the energy storage molecule ATP.
  • The electron gets to photosystem I where it goes to pigments at P700. It absorbs light energy, the electron is promoted to a higher energy level, and passed to an electron acceptor. This leaves a space for another electron which is then replaced by one from photosystem II.
  • in the ETC, the molecule NADP is reduced to NADPH by providing H+ ions. NADP and NADPH are integral to the Calvin cycle where monosaccharides or sugars like glucose are produced after the modification of several molecules.

"The goal during digestion is to break carbohydrates, proteins, and lipids down into smaller units, including ____."
Viktor [21]

Glucose,  amino acids, lipids and glycerol.

Explanation:

Carbohydrate is broken into glucose molecules

protein is  broken into amino acids

Lipid is broken into fatty acids and glycerol.

Starch present in the food is broken to glucose molecules to yield energy.

Protein is digested in stomach by the action of pepsin, trypsin and chymotrypsin.

Glycosidic bonds of starch is broken down by salivary and pancreatic amylase enzyme.

fat is acted upon by lipase enzymes from pancreatic and intestinal juices.

these are broken into smaller units so that gets absorbed by blood and carries throughout the body.

HELP ASAP I WILL GIVE BRAINLIST!!! Read the given chemical reaction.
daser333 [38]

Answer:

4.2moles

Explanation:

"The answer to your question is 4.2 moles of H₂O

Explanation:

Data

moles of H₂O = ?

moles of C₂H₆ = 1.4

Balanced chemical reaction

2C₂H₆ + 7O₂ ⇒ 4CO₂ + 6H₂O

Process

To determine the moles of H₂O, use proportions and the coefficients of the balanced chemical reaction.

2 moles of C₂H₆ 6 moles of H₂O

1.4 moles of C₂H₆ x

x = (1.4 x 6) / 2

x = 8.4/2

x = 4.2 moles of H₂O"
