Answer:
FALSE
Explanation:
Ionization energy is the minimum amount of energy required to discharge an electron from its orbital shell from an atom in ground electronic state. The closer the electron, that is to be discharged, is to the nucleus of the atom, the harder to remove it hence has high ionization energy. In addition, if the nucleus of the atoms has a higher mass and the electron is even closer, the higher the ionization energy.
Answer:
Carbon cycle may be defined as a type of biogeochemical cycle that regulates the amount of carbon in nature. The carbon is released by the living animals and utilized by the plants in form of carbon dioxide.
Photosynthesis consumes the carbon dioxide to make carbohydrates where as cellular respiration releases carbon dioxide and breakdown the carbohydrate. Both these process helps in recycling of the carbon in nature and maintains the level of carbon in nature.
The answer is c. their gametes do not require water for fertilization to occur.
<span>Fertilization is the process in which two gametes fuse which first creates a zygote and then leads to the development of an embryo. Pollination is a transfer of male pollen to the female reproductive organ. </span><span>After pollen lands on the stigma, pollen tube begins to grow until it reaches an ovule which is inside the ovary. A nucleus of pollen will fuse with a nucleus of the ovule and that fertilization will occur. </span>
Answer:
1. Chlorophyll absorbs light
2. Water split to start electron transport chain
3. ATP produced
4. ATP used to build glucose form carbon dioxide
Explanation:
Photosynthesis is the process whereby green plants synthesize their food (glucose) in the presence of sunlight. This photosynthetic process occurs in two major stages viz: light dependent and light independent phases.
In the light dependent phase, the following occurs sequentially:
- Chlorophyll absorbs light energy from sun
- The energy is used to split water molecule in a process called PHOTOLYSIS OF WATER in order to start electron transport chain.
- The electron transport chain yields ATP and NADPH, which will be used in the next phase.
In the light independent phase, also called, CALVIN CYCLE, ATP is used to power the formation of glucose from carbon dioxide
