Im confused please help me!
Harman [31]

Answer:

 The Geographic barrier would have led to speciation in the finches which started from the founder effect where the finches were brought to other areas of the Galapagos. They were separated geographically so they could not mate with each other. Over time, evolution occurs through natural selection and genetic drift. This leads to the population being so different so they have reproductive barriers and can no longer interbreed. They become different species.

Explanation:

Hope this helps you understand better.

In plants, chloroplasts are necessary for A. respiration. B. photosynthesis. C. secretion. D. both respiration AND secretion. E.
Ksivusya [100]

Answer:

B- Photosynthesis

Explanation:

Chloroplasts are <em>chlorophyll-containing, eukaryotic cell structures</em> that function in photosynthesis by absorbing energy from sunlight, combining this energy with water and CO2 to convert them to sugars . This cell structure is known as a plastid. The sugars produced, are important for the survival of the plant.

Chloroplasts reproduce on their own, independent of the whole cell because they contain their own DNA. Plant chloroplasts are located  in guard cells in plant leaves. Closely linked to these guard cells are tiny pores called stomata, which allow gas exchange required for photosynthesis.

Photosynthesis occurs in two stages:

  1. The light reaction stage
  2. The dark reaction stage

The Light reaction stage takes place in the presence of light. Clorophyll converts light into chemical energy in the form of ATP and NADPH. Both molecules produced, are used in the dark stage to produce sugar.

In the dark reaction stage, the stroma, containing enzymes, facilitates reactions leading to the production of sugars from ATP and NADPH. This process is also called the carbon fixation stage. The sugar produced can be stored in the form of starch for other processes such as respiration.

What happens to the states of matter when the temperature changes
stepladder [879]

    They may either release heat or gain heat. With a temperature increase, the kinetic energy increases and the state of matter will increase (example, ice to water aka solid to liquid)

    If the temperature decreases, then the kinetic energy decreases and the state of matter will decrease (example, water vapor to water aka gas to liquid)

Have a nice day!

    I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly. (ノ^∇^)
