Answer:
When rabbit dies, the nitrogen in the rabbits body is released into the soil by decomposition.
Explanation:
When rabbit dies its body is decomposition takes place. Decomposition is process of breaking down of the dead remains of the plants, animals and insects into tiny pieces by free living bacteria, fungi and worms present in the environment
.
During the decomposition process the nitrogen present in the dead rabbit body is released into the soil in the form of ammonia. The bacteria(nitrifying bacteria) present in the soil converts this ammonia into nitrates so that it can be again used by the plants. Now plants intakes this nitrates for photosynthesis process. This process of fixing nitrogen back into the atmosphere is called nitrogen cycle.
All of them should be correct except for the upper left box of question 8. The correct genotype of the box should be WW instead of Ww.
When making a punnett square, all the results in the 4 boxes are combinations of the alleles present in the parents. The different combinations in the square are listed according to the allele on its left and on its top. For example, in question 9, the first box of the square (left upper) should be a combination of R and R, because the allele on the left side and the top (outside the box) are R and R. And the 2nd box, which is the upper right, should be Rr, because the allele on top is r and the allele on the left is R. Always put upper case in front, so the answer is Rr.
Same concept for other boxes, just match the alleles on the top of it, and the left side of it (the ones outside the box), and rearrange the upper/lower cases, and you'll get the correct answer.
D) Methanogen is the awnser
Answer:
To find out the impact of environment on the physical structure of lizard and natural selection.
Explanation:
Ecologists conduct an investigation on the survival of a species of lizards in order to study the impact of environment on the physical body of lizard and natural selection. The ecologists find out that environment has direct impact on the body structure of lizard. Those lizards that spend more time on the ground, have longer legs in order to run fast, while on the other hand, species that lives in the trees usually have shorter legs in order to easily climb on the trees so these body structure helps them in survival and movement.
