Hey there :)
All the options you have given are applicable.
Because xylem and phloem are essentials as they are the veins of the leaves. They are bundled together in thin strands. They allow the movement of water and nutrients.
The veins of leaves are finely branched to be in close contact with photosynthesizing cells as they need to store food.
Industry will have to invest in clean energy solutions like tech to lower carbon emissions (smog) kind of like when legislation was put in place preventing industry from dumping toxic wastes into public areas and waterways.
Answer:
Second Punnett on the first attachment.
Explanation:
In a 4 x 4 Punnett there are a total of 4 squares. Twenty five percent (25%) of 4 is 1. This means that only 1 square out of the 4 should have the genotype that you are looking for.
Okay going at it in a biological sense. Because red eyes is dominant, we know that the allele should be represented by a capital R. It is X-linked, so it should be on the X. The problem is looking for the probability of a male offspring so the combination should be XY (this means the offspring is male, XX is for females).
So taking that all together, you're looking for the genotype combination:

So you need to find the Punnett that has only 1 square with this combination. The attachment shows which specific Punnett:
Answer: Enzymes are macro molecular biological catalysts that accelerate chemical reactions.
(a substance produced by a living organism which acts as a catalyst to bring about a specific biochemical reaction.)
