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>

Seed size in a plant is a polygenic characteristic. A grower crosses two pure-breeding varieties of the plant and measures seed
Juli2301 [7.4K]

Answer:

The F1 progeny is completely heterozygous for the <em>loci</em> of interest since they were obtained by mating between two pure-breeding plant lines. In the next generation, the backcross progeny will have homo-zygous individuals and therefore they will be more variable, resulting from meiosis in F1 hybrids

Explanation:

An F1 resulting from the cross between two pure-breeding plant lines will produce all hybrid individuals, all of them genetically (and phenotypically) identical. Meiosis in F1 hybrids is well known to produce homo-zygous genotypes and thus increases genetic diversity in progeny. For instance, for a single <em>locus</em>, the expected ratio of genotypes obtained from crossing two heterozygous parents is 1:2:1, i.e., one homo-zigous dominant individual, two heterozygous individuals (genetically identical to the parents) and one homo-zygous recessive individual; while the expected phenotypic ratio is 3:1 (i.e., 3 dominant expressing: 1 recessive expressing​).

2) If the foliation on a rock is running north-south what direction is the tectonic pressure coming from?
vovangra [49]

Answer:

if the foliation on a rock is running north-south, the pressure might be vertical (for instance, up to down)

Explanation:

The pressure is the second most principal factor that influences metamorphic rocks. It originates from the weight of the own materials, their densities, and the deepness.  

Litostatic pressure originates from the weight of materials in the interior of the crust.

Pressure generates alignment of materials (foliation and schistosity) and mineral rotation.

There are different types of metamorphism.

Dynamic metamorphism is the one where pressure is the principal factor. It generates by tectonic conditions, and it presents mainly in failure or fracture areas. It provokes trituration and recrystallization of minerals.

Classification of the metamorphic rocks according to their structure:

  • Granulation
  • Recrystallization
  • Metasomatism
  • Massive
  • Foliation

Foliation refers to dynamic metamorphism, where pressures act and minerals orientate perpendicular to the pressure direction.

<em>According to this concept, if the foliation on a rock is running north-south, the pressure might be vertical (for instance, up to down) while minerals' weight helping in the process of foliation. </em>
