Answer:
Yes, photosynthesis is a chemical change
Explanation:
Photosynthesis is the process through which plants convert light energy into chemical energy. Here is the chemical reaction involved: water and carbon dioxide combine to form glucose and oxygen. Since new chemical species are formed, photosynthesis is clearly a chemical change.
Answer:
C) semipermeable
Explanation:
because permeable means it allows things through, and then semi makes it to where it only allows certain things through
and Impermeable means it won't let things through and the other two options just don't make sense for the question
The genotypes would be bbTT X BbTt
Assuming that bark color is represented by B (b) allele and height is represented by T (t) allele.
Since the traits show simple dominance: blue (B) of dominant over purple (b) and tall (T) is dominant over short (t)
- The genotype of a tree that is purebred purple (bb) and tall (TT) would be bbTT
- The genotype of a tree that is heterozygous for both trait would be BbTt
- Thus, the cross would be bbTT x BbTt

Answer:
algal growth due to eutrophication
Explaination:
Eutrophication is where these nutrient rich compounds mix with nearby water sources and promote the growth of large amounts of algae. Algae go through respiration and take up the dissolved O2 in water which causes these areas to experience low O2 levels. Everything needs O2 to survive thus nearby organisms and plants die out creating dead zones.
Answer: Process B because it will reduce our dependency on fossil fuels.
Explanation:
Biofuels are the fuels which are produce by animals and plants matter. These fuels are generated by renewable sources like plants and animals which can be grown again for production of these fuels. These fuels limits our dependency on non-renewable fuels like coal, petrol and natural gas. Therefore, the non renewable fuels will remain available to fulfill the future generation needs. Hence, will help in conservation.
