Answer:

D. 3:1

Explanation:

Gregor Mendel, in one of his numerous studies, performed a cross between purebred dominant (TT) pea plants and purebred recessive (tt) pea plants. All the offsprings of this cross appeared heterozygous tall (Tt) in the F1 generation.

However, when he self-crossed the F1 generation i.e. Tt × Tt, Mendel obtained a phenotypic ratio of 3 tall plants (dominant traits) : 1 short plant (recessive). This showed that the masked gene (recessive) was still present.

Which type of organic molecule is wax?
Elena L [17]
<span>Wax is a simple form of lipid molecule. It consists of a long-chain of alcohol and a fatty acid. Many of the natural occurring wax found in nature are used as ingredients for products found in stores like ointments, hand cream, and cosmetics.

Plants have naturally occurring wax on their leaves and stems; these serve as coatings to prevent them from losing excess water. Other forms of wax found in nature are beeswax, used by bees to make their cones for honey and eggs; sperm whales have spermaceti wax found in their blubber; and carnuba wax, is an ingredient commonly used for car waxes, commonly found in Brazilian palm trees. </span>

AVprozaik [17]

Highly porous and permeable

Explanation:

Compared to other types of rock layers, an aquifer is highly porous and permeable.

Aquifers are always the target when prospecting for ground water in a formation.

  • Porosity is the amount of void spaces in a rock.
  • Aquifers are highly porous .
  • Permeability is the inter-connectivity of the void spaces and their ability to transmit fluids.
  • Aquifers have very high permeability compared to other rock types.

In terms of permeability and porosity, an aquifer is higher porous and permeable.
