Hypoxic waters kill high levels of aquatic species, disrupting the food chain and habitat. In addition to wrecking ecological havoc, the dead zone can be a financial drain on coastal communities.

Choose all of the ways that cellular respiration is different from photosynthesis. Select the 4 correct answers. *

shepuryov [24]

Answer:

It uses glucose as a reactant.

It uses oxygen as a reactant.

It makes ATP.

It happens in the mitochondria.

Explanation:

It occurs in cells. - this is false. Both cellular respiration and photosynthesis occur in cells.

It uses glucose as a reactant. - this is true. Cellular respiration uses glucose as a reactant, it is broken down to release energy. Photosynthesis produces glucose.

It uses oxygen as a reactant. - this is true. Cellular respiration uses oxygen as a reactant. In contrast, photosynthesis releases oxygen as a byproduct

It makes ATP. - this is true. Cellular respiration makes ATP. Photosynthesis uses energy to produce the sugar which is used in cellular respiration to synthesise ATP.

It happens in the chloroplasts. - this is false. Photosynthesis occurs in the chloroplasts, not cellular respiration

It happens in the mitochondria. - this is true. Respiration occurs in the mitochondria, whereas photosynthesis occurs in the chloroplasts.

It involves oxygen, glucose, carbon dioxide, and water. - this is false, Both photosynthesis and cellular respiration involve oxygen, glucose, carbon dioxide, and water. Photosynthesis produces oxygen and glucose using carbon dioxide and water. Respiration produces glucose and carbon dioxide using water and carbon dioxide.

Describe how the functional units for beta carotene, xanthophyll, chlorophyll a, and chlorophyll b are different. be sure to ide

leonid [27]

The pigments have a similar structure of 40 carbon atoms covalently bonded in a chain. Carotenoids contain oxygen atoms in their chemical structure (retinyl functional group) while xanthophyll does not. This makes carotenoids more non-polar compared to xanthophylls, hence move farthest in chromatography paper using a nonpolar mobile phase. Chlorophyll pigment, on the other hand, has chlorin rings (which are larger) as functional units hence move slowly in chromatography.

Photosynthetic rates can be measured by either the amount of oxygen they consume per particular time period or the amount of carbon dioxide produced per particular time period. This is conducted while immersed in water so as to measure bubble rate formation in case of oxygen production or the change in water pH in the case of carbon dioxide consumption.

When autumn approaches, the amount sunlight received by the plant is reduced due to longer night than days. Deciduous trees have adapted by losing chlorophyll a and b pigments (most important in photosynthesis) during this time. This leaves a higher amount of the other red and yellow pigments hence making the leaves change from green to yellow-red.

It is believed that this is the result of an ancient endosymbiotic relationship between a protist and a eukaryotic cell. The protist generates energy that the eukaryotic can utilize in its growth and reproduction while the protist is sheltered. This relationship became obligatory symbiosis over time.

How are stromatolite fossils evidence of earths early life?

solmaris [256]

Answer:

Early cyanobacteria in stromatolites are thought to be responsible for increasing the amount of oxygen in the primeval Earth's atmosphere through their continuing photosynthesis. They were the first known organisms to photosynthesize and produce free oxygen.

Hope this helps!!!
