Biology Photosynthesis questions
Mazyrski [523]

I cannot do the part A task...... I can do the chart (: annddd the questions below..

Glucose: Glucose is a sugar made from sunlight, with the molecular formula C6H12O6.

chloryphll: The energy that is absorbed of the photon is transferred to an electron in a process called charge separation.

ATP: is a product of the first stage of photosynthesis, and it provides energy for the second stage. energy transfer; that is, ATP is able to store and transport chemical energy within cells.

Carbon dioxide: is involved in the production of refrigeration systems, welding systems, water treatment processes

chloroplast: contains the molecule chlorophyll, which absorbs sunlight for photosynthesis.

stomoata: control the flow of gases in and out of leaves.

Thylakoid: A thylakoid is a membrane-bound compartment inside chloroplasts and cyanobacteria. They are the site of the light-dependent reactions of photosynthesis.  surrounded by a lunon.

stroma; involved in the Calvin Cycle – carbon fixation, reduction and regeneration. the stroma the supportive tissue of an epithelial organ, tumor, gonad, etc.

----------------------------------

Q2: oxygenic photosynthesis and anoxygenic photosynthesis.

Q3: The general principles of anoxygenic and oxygenic photosynthesis are very similar, but oxygenic photosynthesis is the most common and is seen in plants, algae and cyanobacteria.

Q4: water, light and carbon dioxide, while the products are oxygen and sugars.

Q5: carbon dioxide + electron donor + light energy ==> carbohydrate + oxidized electron donor + water

CO2 + 2H2A + photons ==> [CH2O] + 2A + H2O

How do models provide a practical solution for some scientific research? Check all that apply.
suter [353]

Models show systems that are large, small or complex.They make it easy for study through zooming in an area in a large system.They provide visual presentation of an object or a system that has been created through experimental data.

Explanation:

A model is a representation of an idea, a process or an object in a system used by a scientist to describe a phenomenon that is difficult to be experienced directly.The goal of a model is to ensure that the presentation is done in a logical and objective way.

The monarch butterfly can be found in a wide range of areas across Canada and the northern United States during the spring and
hichkok12 [17]

In order to survive the winter, monarch butterflies "migrate to warmer areas".

<u>Option: B</u>

<u>Explanation:</u>

  • The survival for Monarch butterflies is not possible in any of the United States 'cold winters, therefore they are needed to migrate south and west every autumn to avoid the cold temperatures.
  • This species migration usually begins around every year in October, but may begin quicker if the weather turns cold earlier than that.
  • Thus they spend their winter hibernation all year round in Mexico and some areas of Southern California where the temperature is warmer.
  • If the monarch stays in the Eastern states, typically east of the Rocky Mountains, then they will migrate to Mexico and hibernate in <em>oyamel fir</em> trees.
