Answer:
okay so im guessing they want you to compare 2 different land resources. Say a water power station and a coal mine for example.
you could state the different effects the coal mine would have in comparison to the water station.
the coal mine say has pollution produced as a result in producing the energy. Whereas water has a lot better environmental value, but might cost more to produce energy
there is a lot of information of the 2 on google :)
Answer:
your answer would be B. the vascular tissue
Explanation:
There are two principal tissue types that make up the veins of plants: The xylem moves water and minerals. This flows from the plant’s roots upwards. The phloem moves food energy around the plant. This flows in whichever direction the plant needs it to flow. These two tissue types make up the vascular bundle of the plant.
hope you have a nice day

- Males only have one X chromosome, while females have two X chromosomes.
Answer:
100%, 50%
Explanation:
<em>A testcross involves crossing an organism of unknown zygosity with its homozygous recessive version.</em>
Assuming the purple flower pea plant is homozygous for the trait with genotype PP and it is crossed with homozygous recessive pea plant pp.
PP x pp = Pp, Pp, Pp, and Pp
100% of the progeny will be purple in appearance.
On the other hand, assuming the purple flower pea plant is heterozygous with genotype Pp and this is testcrossed with a pp plant.
Pp x pp = Pp, Pp, pp, and pp
50% of the progeny will be purple and the remaining 50% will be white.
<em>Hence, If you were to perform a test-cross to determine the genotype of a purple-flowered plant, you would expect the percentage of purple-flowered progeny to be </em><em>100%</em><em> if the plant is homozygous and </em><em>50% </em><em>if the plant is heterozygous.</em>
