The answer is B Animal cells do not have a cell wall and the shoe box represents the cell wall. Hope this helped!
Answer:
3
Explanation:
Heterozygous mice at both loci would be BbAa genotype.
B (black) is dominant over b (white) but the presence of A results in agouti.
Crossing two heterozygous:
BbAa x BbAa
Progeny
<em>9 B_A_ - Agouti</em>
<em>3 bbA_ - agouti</em>
<em>3 B_aa - Black</em>
<em>1 bbaa - white</em>
Hence, 3 out of 16 progeny will be black in color.
<em>See the attached image for the Punnet's square analysis of the cross.</em>
I believe the correct answer is option C. Weathering produces the sediments that ultimately lead to soil formation. Soil formation is the result of a combination of five factors: parent material, climate, topography, biological factors, and time. Hope this answers the question.
The environment is studied at different levels & stages.
Biosphere: The biosphere is the zone in which life exists. It consists of the atmosphere& the hydrosphere alongwith the earth surface where living beings live.
The biome is a community of plants and animals (flaura & fauna).
Community: A community is a group of people/living beings who live in a specific location. It is used to describe two or more populations of different species that exist at same place.
Population: A population is the multiple individuals or living organisms of a single species that live in an area.
The populations are formed by lalrge number of groups of organisms.
Group of populations form communities. The group of all communities form a biome, which exist in the biosphere.
