In the US, 1 in 1700 Caucasian children will be born with the monogenic hereditary disorder Cystic Fibrosis (CF), a pathology that results in an accumulation of abnormally sticky and thick mucus affecting the lungs and digestive system. Consider a small isolated community in Appalachia where most of the population lives below the poverty level and where adults have a higher rate of CF that the national average since the people tend to marry neighbors. The general practitioner for the county receives a Bill and Melinda Gates Foundation Grant to ascertain how many children in the community inherited cystic fibrosis from their parents. Out of 172 children tested, she finds 38 have CF. Remember that Mendel believed in diagnostic ratios for understanding inheritance outcome although other factors can come into play like assortative mating.

Answer:

nuclear fission

Nuclear power comes from nuclear fission

The steam is used to spin large turbines that generate electricity. Nuclear power plants use heat produced during nuclear fission to heat water. In nuclear fission, atoms are split apart to form smaller atoms, releasing energy

In nuclear power plants, neutrons collide with uranium atoms, splitting them.  In the core of nuclear reactors, the fission of uranium atoms releases energy that heats water to about 520 degrees Farenheit. This hot water is then used to spin turbines that are connected to generators, producing electricity

competition plays a very important role in ecology and evolution. The best competitors are the ones who survive and get to pass on their genes.

Answer:

It is D

Explanation:

Self-pollination occurs when the pollen from the anther is deposited on the stigma of the same flower, or another flower on the same plant. Cross-pollination is the transfer of pollen from the anther of one flower to the stigma of another flower on a different individual of the same species.

Answer:

The term "phenotype" refers to the observable physical properties of an organism; these include the organism's appearance, development, and behavior. An organism's phenotype is determined by its genotype, which is the set of genes the organism carries, as well as by environmental influences upon these genes.

Explanation:

Answer:

It basically means that everyone is a genius in their own way and everyone has their own skills. If you decide to judge someone on what they cannot do (eg. a fish climbing a tree) rather than what they can do, it's gonna make the person feel $tupid their entire life. Not everyone can do the same thing and not everyone has the same abilities. A fish may not be able to climb a tree, but it can swim well. Just like a bee wouldn't be able to swim, but it can fly.

Answer:

Water will move into and out of the cell at the same rate, causing it to remain the same size.

Answer:

The correct answer is -

The phenotype of offspring (first cross or F1): 100% tall

The genotype of offspring (first cross or F1 - 100% Tt or heterozygous)

The phenotype of offspring in F2 (F1 × F1) - 3:1 (3 tall: 1 dwarf)

The genotype of offspring in F2 (F1 × F1) - 1:2:1 (One dominant tall: two heterozygous tall: one dwarf)

Explanation:

In this experiment of Mendel, Mendel selected the pea plant as it has various characters, short life span, and easy to breed. For this, he used two true breed lines, tall plants that had dominant allele TT and dwarf plant tt (recessive). In presence of the dominant allele, recessive alleles do not show their characteristics and only express if both alleles are recessive.

In the first cross of TT and tt

Gametes: T and t

offspring: Tt

the offsprings are all tall and heterozygous which means one dominant and one recessive allele.

second cross or F1 × F1

Tt × Tt

gametes: T, t and T, t

offspring: TT, Tt, Tt, tt

Thus,

The phenotype of offspring (first cross or F1): 100% tall

The genotype of offspring (first cross or F1 - 100% Tt or heterozygous)

The phenotype of offspring in F2 (F1 × F1) - 3:1 (3 tall: 1 dwarf)

The genotype of offspring in F2 (F1 × F1) - 1:2:1 (One dominant tall: two heterozygous tall: one dwarf)

Answer:

1. 0.79g/mL

2. Ethanol

Explanation:

The density of a substance can be calculated by using the formula;

Density (g/mL) = mass (g) ÷ volume (mL)

According to the information provided in the question, mass = 11.85grams, volume = 15mL.

Hence, density = 11.85g ÷ 15mL

= 0.79

Density of the liquid = 0.79g/mL.

Substances usually have their own unique density, which is one of the properties that distinguish them. In this case, ETHANOL is the liquid that possesses a density of 0.79g/mL.

Answer:

incomplete dominance

Explanation:

This is because incomplete dorminance is a type of inheritance pattern in which a dorminant allele does not completely masked the effect of recessive allele. The recessive allele is expressed little and the dorminant. Example is the nose size. The allele for big nose and recessive allele for small nose are not completely dorminant.

Answer:

xylem, plant vascular tissue that conveys water and dissolved minerals from the roots to the rest of the plant and also provides physical support. Xylem tissue consists of a variety of specialized, water-conducting cells known as treachery elements. The vascular system is comprised of two main types of tissue: the xylem and the phloem. The xylem distributes water and dissolved minerals upward through the plant, from the roots to the leaves. The phloem carries food downward from the leaves to the roots.
