Answer:
Taproot systems feature a single, thick primary root, called the taproot, with smaller secondary roots growing out from the sides. The taproot may penetrate as many as 60 meters (almost 200 feet) below the ground surface. It can plumb very deep water sources and store a lot of food to help the plant survive drought and other environmental extremes. The taproot also anchors the plant very securely in the ground.
Fibrous root systems have many small branching roots, called fibrous roots, but no large primary root. The huge number of threadlike roots increases the surface area for absorption of water and minerals, but fibrous roots anchor the plant less securely
Explanation:
Answer:
he term “homologous structures” refers specifically to similar structures found in different species that have a common ancestry or developmental origin. Note that homologous structures don’t have to perform the same function in a species, the only requirement is that they are similar in form and exist in species with common ancestry.
Explanation:
Answer:
0.1% of energy
Explanation:
Energy flow: From the whole quantity of energy that reaches the earth's surface, autotroph organisms or producers absorb only 0.1 or 1%.
From the input of solar energy begins a unidirectional energy flow through all the organisms in the ecosystem, from autotrophs to heterotrophs, until it is dissipated in the environment.
At each trophic level occurs an energy transfer to the next, with only 10% being usable in each of them. This assessment is called "The 10% rule". As a general rule, only about 10% of the energy stored as biomass at one trophic level, per unit time, ends up as biomass at the next trophic level, in the same unit of time.
If wheat transferred 10% of the energy to mice, and of that 10% mice transferred 10% of the energy to hawk, then the percentage of energy transferred from the first trophic level to the third equals 0.1%.
10% (1st TL-2nd TL) / 10% (2nd TL - 3rd TL) = 0.1% (1stTL - 3rd TL)
<em>TL = Trophic level </em>
Answer:
The correct answer is option C.
Explanation:
As it is given that, a Mendelian cross is performed between two parents resulted by cross the parents. This suggests that the parents or P generation has zero recombination hence the genotype of Parents would be AA and aa in nature. Therefore, all the F1 generation offspring were Aa in nature. The selfing of the F1 offspring will be:
A a
A AA Aa
a Aa aa
Genotype: AA: Aa: aa :: 1:2:1
Phenotype: Dominant: recessive :: 3:1
