ATP and NADPH transfer chemical energy to 3-PGA.
Glyceraldehyde 3-phosphate (G3P) is created.
G3P is used to make sugar.
Answer: The energy from the sun passes through space in the form of invisible waves to the earth surface. It heats up the earth’s surface causing variation in climate.
Explanation:
The amount of incoming energy from the Sun decides the weather and climate of earth. If the energy that is incoming and outgoing on the earth, then climate is in equilibrium. The balance is depending on the scattering, absorption, reflection and transformation of energy.
The energy from sun passes through space and reaches the earth’s surface. On reaching surface, the solar energy warms the atmosphere releasing heat energy which gets transferred throughout the planets system by radiation, conduction and convection. Conduction happens in the atmosphere within first several millimeters close to the surface. This heated air expands as it is dense and rises causing transfer of heat to atmosphere through convection process. It results in formation of clouds.
The radiant energy from sun is transmitted via space in form of invisible waves. But much of the suns radiant energy, is transmitted back to atmosphere. The objects on earth like land, plants, animals absorb radiant energy as heat of which one third gets re-radiated back to atmosphere that is absorbed by carbon dioxide and water vapor. The atmosphere radiates heat energy back to earth increasing the earth temperature. This trapping of radiation is greenhouse effect.
The thermal energy obtained by convection currents are responsible for wind, cloud formation, and weather formation. The hydrosphere that comprises of 70% of earth’s surface absorbs solar energy.
On the basis of the above explanation is:
The energy from the sun passes through space in the form of invisible waves to the earth surface. It heats up the earth’s surface causing variation in climate.
<span>Ans: G1 phase
Explanation:
Preparation of a newborn division happens in three steps:
G1 phase, G2 phase and S phase.
In G1 phase, the cell grows physically larger, copies organelles, and makes the molecular building blocks it will need in later steps.
mitosis is the process in which the nuclear DNA of the cell condenses into visible chromosomes and is pulled apart by the mitotic spindle, a specialized structure made out of microtubules.</span>
Answer:
B. Stable ecosystems
Explanation:
The main cause of the biodiversity experienced in rain forests is largely due to the stable ecosystems that they enjoy.
A stable ecosystem is a sustainable one that does not change too much over the course of time.
Most organisms and the diverse life forms are easily nourished by the provisions made available by nature in such regions.
- Most rain forest receives a large amount of solar radiation and energy all year round as the sun is directly overhead here.
- This suggests that the producers have enough energy to cater for their own need and that of the organisms there in.
- The consumers and decomposers have sufficient food available all year round.
- This coupled with other factors whereby organisms have specially adapted to environmental conditions makes a rain forest very biodiverse with life forms.
- An unstable ecosystem cannot be biodiverse
