Explanation:

Photosynthesis takes place within the chloroplasts.

Photosynthesizing cells in algae and plants have structures called chloroplasts. These contain chlorophyll, a specialized compound which facilitates the conversion of light energy to energy stored in carbohydrates in the process photosynthesis. Pigment molecules like chlorophyll in plants and other organisms reflect and absorb light at specific parts of light's electromagnetic spetrum.

Photosynthesis is a chemical pathway that’s integral to producing energy in plants and other primary producers. Energy in the form of molecules of glucose is produced from light, water and carbon dioxide while oxygen is released. This occurs in several complex steps, photosynthesis is a rate limited reaction, depends on several factors including carbon dioxide concentration, ambient temperature and light intensity; the energy is retrieved from photons, I.e. particles of light, and water is used as a reducing agent.

Water supplies the chlorophyll in plant cell with replacement electrons for the ones removed from photosystem II. Additionally, in the light dependent reactions, within chloroplasts of plants, water (H2O) split by light during photolysis into H+ and OH- acts as a source of oxygen along with functioning as a reducing agent; it reduces the molecule NADP to NADPH by providing H+ ions. NADP and NADPH are integral to the Calvin cycle where monosaccharides or sugars like glucose are produced after the modification of several molecules.

What is the relationship between temperature and abundance life

xenn [34]

Answer:

As average temperatures at the Earth's surface rise, more evaporation occurs, which, in turn, increases overall precipitation. Therefore, a warming climate is expected to increase precipitation in many areas.

Natural selection acts on a variation of populations of living things usually through a specific trait which statement must be t

Andreas93 [3]

Considering the following statements;
A. The trait is the same for all organisms
B. The trait is resistant to mutations
C. Most forms of the trait have the same impact on survival
D. The trait is passed on genetically to the next generation
The correct answer is D.
Genetic variation is essential for natural selection since natural selection can only increase or decrease frequency of alleles that already exist in the population. Genetic variation is caused by mutation and random mating organisms.

2. Why is this change in global temperature a concern

12345 [234]

Past climate changes led to extinction of many species, population migrations, and pronounced changes in the land surface and ocean circulation. The speed of the current climate change is faster than most of the past events, making it more difficult for human societies and the natural world to adapt.
