B) They should test their hypothesis before coming to that conclusion.
The answer is B and D i learned this in biology last week
Answer:
20 large size leaves plants
40 medium sized leaves plants
20 small sized leaves.
Explanation:
PP = large leaves
P'P' = small leaves
PP' = medium leaves
PP' was crossed with another PP' plant:
PP' x PP'
progeny = PP, 2PP', and P'P'
PP = 1/4 x 80 = 20 large size leaves plants
PP' = 1/2 x 80 = 40 medium sized leaves plants
P'P' = 1/4 x 80 = 20 small sized leaves.
<em>Hence the phenotypes would be:</em>
<em>20 large size leaves plants</em>
<em>40 medium sized leaves plants</em>
<em>20 small sized leaves.</em>
Answer:
Inorganic or Mineral Matter.
Explanation:
The mineral matter belongs to one of the physical components of the soil. It is about 45% of total volume of the soil. It contains nutrients like nitrogen, nitrogen, calcium, magnesium, iron etc. It holds water and can also hold air for plant use.
It serves as the home for soil organisms which may improve plant growth. Soil mineral also form the solid part of the soil, providing support for plants and also prevents leaching in soil erosion and evaporation of soil water.
