Cystic fibrosis is a genetic disorder in which a particular gene does not make protein the way that it otherwise normally would.

Nadya [2.5K]

The answer is A because genetic means it comes from your genes/parents genes so you know it’s either A or B because they both state something about your parents passing it to you. But you know it can’t be B because chloroplasts are only in plants and A says chromosomes which are in humans and relate to genes so we know it must be A.

Which observation would provide indirect evidence that supports a hypothesis that the bubbles are o2 ?

zhuklara [117]

Explanation:

D. An increase in bubbles on the plant when it is moved under a brighter light.

The rate of photosynthesis increases with light intensity.

The process of photosynthesis is energy-storing, it converts light energy into chemical energy, which is stored in the bonds of glucose. Thus an increase in light intensity would increase the rate of photosynthesis, and more O2 bubbles would be produced as waste.

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.

Occurring 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. 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; it reduces the molecule NADP to NADPH by providing H+ ionsand produces molecules of the energy storage molecule ATP through an electron transport chain.

This occurs in the thykaloids, where pigment molecules like chlorophyll reside. Later, in dark reactions, NADP and NADPH are used in the Calvin cycle where monosaccharides or sugars like glucose are produced after the modification of several molecules. These store energy in their bonds, which can be released in respiration in the mitochondria.
