Answer: Calvin cycle is the second stage of photosynthesis and does not require light.
Explanation: Photosynthetic reactions are divided into two phases: light dependent reactions and carbon fixation reactions. Light dependent reactions is the first stage of photosynthesis in which sunlight is used to split a molecule of water and the energy generated is conserved in form of ATP and NADPH.
Calvin cycle is the second stage of photosynthesis. It is also called carbon fixation reactions. These reactions do not need light to occur. It occurs in the dark, the ATP and NADPH produced in light dependent reactions are used to drive these reactions. In Calvin cycle, carbon dioxide is assimilated through a cyclic pathway to produce triose phosphate which is a precursor for glucose and other related molecules such as starch.
The Calvin cycle is the second stage of photosynthesis.
The correct statement is the second stage of photosynthesis. The Calvin cycle is a series of reactions that occur in the stroma of chloroplasts in plants. It takes place after the light-dependent reactions and uses the energy stored in ATP and NADPH to convert carbon dioxide into glucose. This cycle does not directly produce water and does not require light.
Also known as the Calvin-Benson cycle, is a series of biochemical reactions that take place in the stroma of chloroplasts during photosynthesis. It converts carbon dioxide and energy from ATP and NADPH into glucose and other organic molecules. The Calvin cycle is a crucial part of the light-independent reactions of photosynthesis.

FALSE
Answer:
It is false
Explanation:
They do have an effect on global climate like natural disasters
Local environmental changes, such as deforestation and industrial pollution, can contribute to global climate change by increasing levels of greenhouse gases.
The statement that local environmental changes have no effect on the global climate is FALSE. Even local changes can have drastic effects on the global climate over time. For example, deforestation in a local area can lead to an increase in greenhouse gases, contributing to global warming. Similarly, industrial pollution in a local region can also intensify climate change by releasing large quantities of CO2 and other gases into the atmosphere.

B.bone cells only
C.skeletal muscle cells only
D.skin,bone,and skeletal muscle cells
Answer: None of these options.
Hope it helps!!
Explanation: Skeletal muscles are made up of connective tissue, blood vessels and nerves. they help in the movement of the body parts, protect the bones and joints also provide skeletal stability. In reality theses cells never divide. The myoblasts divide at the embroyonic stage and these are formed. When damaged the missing tissue is filled by adding new proteins and enlarging. So in reality they so not divide so no option fits here.
