Answer:
<u>Option:</u>False.
There are billions of microorganisms including bacterial life, archea, insects and many other living beings which resides inside the various layers of the soil.
Explanation:
There more then billions of a microorganisms which lives inside the various layers of the soil and mainly performs the function of decomposition inside the environment, which leads to break down of macro-molecules inside the environment and enough energy is released by the breakage of bonds present on molecular level. As the optimum amount of energy is required to drive all the cellular processes and more over for the sake of conservation of energy inside the biosphere.
- <u>Fertility of the soil and fixation process:</u>
The fertility of the soil is greatly effected by the right amount of microorganisms present in it. As the microorganisms along with other insects and bacterial life greatly effects the fertility of any soil sample.
1) "Lustrous appearance with solid form"
2) "Intermediate Electrical conductivity"
3) "Intermediate Ionization energy and Electronegativity"
4) "Non-metallic in chemical behavior but can form alloys"
Hope this helps
I think it is C, since it does occur on land life, and I think it also occurs in marine life.
Additional information is missing. It is as follows: In fruit flies, the allele for red eyes is dominant over the allele for pink eyes. Straight wings are dominant over curled wings.
Answer:
Genotype = RrSS and RrSs in 1:1 ratio so each has 0.5 probability
Phenotype = All red eyed and straight winged
Explanation:
Given,
Red eyes (R) is dominant over pink eyes (r)
Straight wings (S) is dominant over curled wings (s)
Fly 1 : Homozygous red eyed, curly winged = RRss
Fly 2 : Pink eyed, heterozygous straight winged = rrSs
RRss will produce Rs gametes and rrSs will produce rS and rs gamates.
When fly 1 and fly 2 mate : RRss X rrSs :
rS rs
RS RrSS RrSs
The genotypic ratio is 1 : 1 ( RrSS : RrSs ) that means that each genotype has 0.5 probability. Both the genotypes though have at least one dominant allele for each gene so the entire progeny will have red eyes and straight wings.
