Answer:

In light algae performs both photosynthesis and cellular respiration.

Algae performs only Calvin Cycle of photosynthesis when kept in dark.

Explanation:

Algae is a multi-cellular organism or unicellular organism which is capable of performing photosynthesis. It contains the pigment chlorophyll which is used to trap sunlight which converts carbon dioxide and water.

Cellular respiration also takes place in the algae and it is a continuous process that takes place all the time.

In case of dark or when there is no light only Calvin Cycle take place.

Answer:

Algae preform both photosynthesis and cellular respiration when incubated in the light.
Algae preform only Calvin cycle of photosynthesis and cellular respiration when incubated in the dark.

Explanation:

Algae do perform photosynthesis and cellular respiration during light just like other plant specie. They use chlorophyll a or b as pigments to collect light energy and drive the process of photosynthesis.

We know that photosysnthesis is basically a two step process i.e light reactions and dark reactions (dark reaction is also called Calvin cycle). So, in dark algae only performs Calvin cycle and shuts off the light harvesting steps of photosynthesis. However, cellular respiration keeps going throughout the life of algae without being affected. We can say that algae share these characteristics with the green plants.

Hope it helps! :)

kotykmax [81]

Answer;
The process of respiration is essential in the oxygen/carbon dioxide cycle. Respiration removes oxygen from the atmosphere and produces and releases carbon dioxide to the atmosphere.

Explanation;
Respiration is one of the natural process that adds carbon dioxide to the atmosphere and at the same time remove or decrease the amount of oxygen.
Both plants and animals use respiration process to generate energy in form of ATP that is needed for basic functions such a growth and movement. During this process, nutrients such as glucose are combined with oxygen to yield energy in form of ATP, and also water and carbon dioxide as by-products.
Unlike photosynthesis, which uses carbon dioxide and water to yield nutrients (simple sugars) and oxygen gas, respiration uses oxygen and nutrients, to yield carbon dioxide and water, we can therefore they are antagonistic processes.

igor_vitrenko [27]

Answer:

Endosymbiosis of an oxygen-using scavenger bacterium in a larger host cell−the endosymbiont evolved into lysosomes.

Explanation:

The evolution of eukaryotic cells in all probability included: endosymbiosis of an oxygen-utilizing bacterium in a bigger host cell−the endosymbiont developed into mitochondria. development of an endomembrane framework and consequent advancement of mitochondria from a segment of the Golgi. endosymbiosis of an oxygen-utilizing photosynthetic bacterium in a bigger host cell−the endosymbiont advanced into mitochondria. endosymbiosis of an oxygen-utilizing scrounger bacterium in a bigger host cell−the endosymbiont developed into lysosomes.

What purpose is served by the loss of an -H and -OH end from two molecules as they join together during dehydration synthesis

makkiz [27]

The loss of the hydrogen on one molecule produces a negative charge, which is attracted to the positive charge formed by the loss of the hydroxy group from the other molecule.
