Answer:

Markovnikov orientation with both syn- and anti-addition

Explanation:

Addition of hydrogen halides to alkenes (hydrohalogenation) show regioselectivity, they obey Markovnikov rule. This is always obeyed in all alkene reactions with hydrogen halides. The major product is always one in which the halide is attached to the carbon with the least number of hydrogen atoms and the hydrogen attached to the carbon with the greatest number of hydrogen atoms across the double bond. However, the reaction is not steroselective. It does not yield a greater percentage of a particular stereo isomer. The reaction yields a 50-50 mixture of both syn- and anti- addition products.

Which of the following human activities would be most beneficial to soil conservation?
kifflom [539]
The best answer is D because construction would be bad for the environment and take up space on the soil that is trying to be preserved. Also, for C, planting only one crop type in soil is not very beneficial to the soil at all. IT is best to plant multiple crops in the soil and move the crops to different parts of the soil each year when planting them.

What is the purpose of the electron transport chain in the thylakoid membrane?
Feliz [49]

Answer:

To produce energy in form of ATP

Explanation:

The thylakoid membrane harbors photosystems that will receive light photons, ejecting electrons from a main chlorophyl molecule in a reaction center, to other acceptors.  These electrons will reach the electron transport chain to create a proton gradient, and subsequently, to produce ATP.  Later on these electrons will reach the other photosystem, to produce reducing power.  This is in plants.

Cyclic photosystems also exist, in some bacteria, for example,  and only produce energy as ATP.  They also have an electron transport chain.

Plant cells have mitochondria, which use glucose to produce ATP. Where does the glucose originate?
Romashka [77]

Plant produces glucose in the chloroplast through the process of photosynthesis. Calvin cycle is basically the biological process through which glucose is produced. The steps involved are as follows:

1. Absorbed CO2 is added to RuBP and 6C sugar is formed.

2. Breaking of 6C sugar into two  3-phosphoglycerate molecules

3. ATP gives phosphate group  to form 3-phosphoglycerate which is later on converted into 1,3-biphosphoglycerate.

4. Electons are required by 1,3-biphosphoglycerate to an aldehyde called glyceraldehyde-3-phosphate or G3P and these electrons are donated by NADPH

5. Enzyme aldolase uses two molecules of G3P to produce 6 C sugar called  fructose-1,6-biphosphate which is further converted to fructose-6-phosphate

6. Enzyme  isomerase converts fructose-6-phosphate to glucose-1-phosphate

One example of a consequence of climate change would be
solong [7]

Answer:

Melting ice and rising seas

When water warms up it expands. At the same time global warming causes polar ice sheets and glaciers to melt. The combination of these changes is causing sea levels to rise, resulting in flooding and erosion of coastal and low lying areas
