Answer:
80 dB
Explanation:
Sound intensity is inversely proportional to the square of the distance traveled by the sound.
Thus;
r1^2 divide by r2^2 = L2divideL1
where r= distance (m)
L= sound intensity (decibal dB)
8squared divide by 4 squared = L2 divide 20 dB
L2 = 4 × 20
L2= 80 dB
This means that the sound is increased from 20 dB to 80 dB.
In most animals, the <u>diploid</u> state of the life cycle is much larger than the <u>haploid</u> state.
The multicellular diploid stage is the most evident life stage in a diploid-dominant life cycle, and the only haploid cells are the gametes. Most animals, including humans, have this kind of life cycle. It is much larger than the haploid life cycle because of the complexity due to diploid stages.
The multicellular (or occasionally unicellular) haploid stage is the most visible life stage and is frequently multicellular in a haploid-dominant life cycle. The only diploid cell in this kind of life cycle is the single-celled zygote. This kind of life cycle is found in some algae and fungi.
Meiosis, which produces haploid cells from diploid ones in all sexually reproducing species, and fertilisation are two examples of fundamental life cycle characteristics that all sexually reproducing species share (the fusion of haploid gametes to form a diploid cell called the zygote).

Answer:
water
Explanation:
in poor soil most of the water would get sucked up into more powerful plants [larger plants]
Mushrooms because they dont use photosynthesis
