Answer:
4. The correct pathway for the flow of electron during photosynthesis is mentioned in option D.
> <em>NADP </em>> <em>Calvin cycle.</em>
- Electron is first provided to the photo-system II by the phtolysis of water.
- Then it is passed to photo-system I with the help of plastoquinone (PQ) and cytochrome
. - Finally, electron from the photo-system II is used to reduce NADP to NADPH.
- NADPH and ATP are used in light independent phase or Calvin cycle to synthesize carbohydrate from carbon dioxide.
5. The correct answer is B.) photosynthesis.
- Photosynthesis is the process by which green plants synthesize glucose or carbohydrate from carbon dioxide and water in presence of sunlight and chlorophyll.
- In light independent phase of photosynthesis, it requires ATP and NADPH in order to synthesize food.
- Lastly, oxidation or breaking down of glucose releases energy and photosynthesis is a anabolic process instead of catabolic one.

Answer:
27 genotypes and 8 phenotypes
Explanation:
Supposing that the genotypes of both of the parents are AaBbDd (A, B and D are dominant over a, b and d). After completing the Punnett square, you can predict the following offspring:
I add an image where you can see all the 27 genotypes and frequencies.
Finally, all the 8 phenotypes with the following frequencies:
27/64 A-B-D-
9/64 A-B-dd
9/64 A-bbD-
9/64 aaB-D-
3/64 A-bbdd
3/64 aaB-dd
3/64 aabbD-
<u>1/64 aabbdd </u>
Total 64/64
Note: when a phenotype is A-, it means that it came from either genotype, AA or Aa. The same applies to B- (BB or Bb) and D- (DD or Dd)
Answer:
Climate change can melt ice in cold regions, and because ice is freshwater it can change the salinity of the oceans. Some marine animals may not cope with these conditions and may die as a result. This threatens biodiversity because there would be less species of marine life in our oceans.
Answer:
- <u>White-bark pine trees:</u>
The specie of plants are found in the most of the national parks of Canada. As they have a high significance in providing more options or ways for the organisms to live. Wildlife is greatly benefited by the presence and increase population of the white-bark pine.
Explanation:
- <u>Effects due to decreased level of White-bark pine trees:</u>
If the population of the white-bark tree is reduced to half, then it will directly effect the level of steep slopes causing destabilization inside it.Along with that, it will also influence and reduce the amount of snow melt by sustaining snow drifts. As decrease in the number of this specie of plant's number will decrease the normal cycle inside the environment, if the cycle is disturbed.Then it will be responsible for the imbalance inside the nature. While it may also cause some of the hazardous events inside the biosphere.
- <u>May cause the decrease in population of the wild life:</u>
There are many species which are benefited by the presence of white bark trees, if the number of white bark tress declines to half then the species present will suffer greatly inside the region. As the support for the species regarding there source of food and shelter will decrease and will bring an imbalance inside the nature.
- <u>Decrease level of vegetation in the region:</u>
Due, to the white bark trees in the area the soil is kept safe from erosion and it increase the supply of nutrients and water towards the plants. As it helps in keeping the soil together which also helps in decreasing the chances of land slides during heavy rainfall in the region.
Now, if the number of the white bark trees declines then it may cause land sliding in the region along with other hazardous events along with it.As the soil capacity to hold itself all together will decrease, causing less water and nutrients transport towards the plants and other beings.
