Earth is composed of layers of material with different properties. Which
Irina-Kira [14]

Answer:

mantle

Explanation:

A mantle is a layer inside a planetary body bounded below by a core and above by a crust. Mantles are made of rock or ices, and are generally the largest and most massive layer of the planetary body. Mantles are characteristic of planetary bodies that have undergone differentiation by density. All terrestrial planets (including Earth), a number of asteroids, and some planetary moons have mantles.

Why does darkness affect the light-independent reactions of photosynthesis?
notsponge [240]

Answer:

The correct answer would be Light independent reactions require the energy gathered in the thylakoids.

Photosynthesis can divided into two sub-processes or reactions:

Light-dependent reaction: It converts solar energy into chemical energy that is, ATP (adenosine triphosphate) and NADPH with the help of photolysisis of water. It takes place in thyllakoid membrane of the chloroplast.

Light-independent reaction: It fixes carbon obtained from carbon dioxide into the food or glucose with the help of enzyme RuBisCO (Ribulose-1,5-bisphosphate carboxylase/oxygenase).

It takes place in the stroma of the chloroplast and does not require the involvement of light however, it requires the products (ATP and NADPH) of the light reaction.

Fixation of 1 molecule of glucose requires 6 molecules of carbon dioxide, 9 molecules of ATP and 6 molecules of NADPH.

So, darkness indirectly affects the light-independent reaction.

ALL BUT one product of the light dependent reaction of photosynthesis is utilized in the light independent reaction. That is
Lesechka [4]

Answer: Oxygen

Explanation: Photosynthesis is a process by which plants use carbon dioxide, water and sunlight to produce glucose and oxygen.

Photosynthetic reactions are divided into two phases: 1). light dependent reactions and 2). light independent reactions.

1) In light dependent reactions, chlorophyll and other light absorbing pigments absorb light energy and conserve it as ATP and NADPH with the simultaneous liberation of oxygen. This reaction occurs only when plants are illuminated. In light reactions, light energy is used to split water molecules into hydrogen ions and oxygen, the hydrogen ions produced are transferred to NADP+ to form NADPH, ATP is also produced in light dependent reactions.

2) In light independent reactions, ATP and NADPH produced in the light dependent reactions are used to drive the light independent reactions in which ATP and NADPH are used to reduce CO2 to form trioses, starch, sucrose and other products derived from them.

Why are estuaries such rich habitats for organisms
andreyandreev [35.5K]
Estuaries are areas where fresh water from rivers meets salt water. As the river drains, it carries much nutrient-rich sediment. Many animal species depend on this food source to provide for their young.
