Answer:
Solid: Tight Compact Liquid: Constantly moving spread out a bit Gas: Quick Really Spread Out And Fast
Explanation:
The correct answer is D. All of the above.
Soil compaction is termed as the compression of particles of small to small volume which are then reduces their pore space size which is being available for water and air.
Soil compaction can result from;
1. Elimination or reduction of pore space in soil.
2. Heavy weight machine on soil.
3. Livestock walking over the soil.
Soil compaction can result to decrease in crop production and increase in erosion of soil.
T he purpose of the soil compaction is that large water pressure which is build up and causes soil liquefy in the time of earthquake.
Answer:
<u>4 types </u>of phenotypes with <u>phenotypic ratio 9:3:3:1 </u>will be obtained.
Explanation:
The Punnett square diagram for the cross between mice with genotype BbCc & BbCc is attached.
It is clear from the diagram attached that the <u>phenotypic ratio</u> will be 9:3:3:1
- The following<u> 9 genotypes</u> will show dominant trait for both the characters i.e. characters represented by B & C genes.
BBCC, BBCc, BbCC, BbCc, BBCc, BbCc, BbCC, BbCc, BbCc
- The following <u>3 genotypes</u> will show dominant trait for one character represented by gene B and recessive trait for other character represented by gene C.
BBcc, Bbcc, Bbcc
- The following <u>3 genotypes</u> will show recessive trait for one character represented by gene B and dominant trait for other character represented by gene C.
bbCC, bbCc, bbCc
- The following genotype is the <u>only genotype </u>which will show recessive trait for both the characters represented by gene B & C.
bbcc
<span>The stinging organelle of paramecium that assists it in capturing large prey is called trichocyst.
It is used by many organisms as both a defense mechanism, as well as for capturing food. The organism uses this organelle so as to paralyze its prey and later eat it.
