Answer:

All options are matched correctly

Explanation:

In a stabilizing selection, the individuals are produced with most average and common traits. It is a selection type that is linked to phenotypic trait. In the case of stabilizing selection, the genetic variance decreases and an average phenotype is favored against the extreme variations.  

In directional selection, phenotypes lying at one end of spectrum are selected. This is the case of peppered moth in England. This selection shifts the genetic variance towards phenotypic characteristics that is fit and adaptable to the changing environment.  

In disruptive selection, two or more different types of phenotype are selected in such a way that phenotypes at the extremes are more fit while the phenotypes in the mid are less fit.

Hence, all the options are matched correctly.

1.What taxon (classification levels) are represented by the scientific name of an organism? What are the rules for writing the s
Ksivusya [100]

<u>Answer</u>:

1.a) Species. It is the lowest taxon and represents the scientific name of the organism.

b) The species name is part of the binomial system of nomenclature developed by Linnaeus.

Thus it is composed of two parts each with its own writing rules (ex. gray wolf - <em>Canis lupus</em>):

A. the genus or generic name

- written first

- always underlined or italicized

- the first letter is always capitalized

ex. <em>Canis</em>

B. the specific epithet or species name

- is written second

- always underlined or italicized

- never capitalized

ex. <em>lupus</em>

<em />

2. The results should always be the same. A dichotomous key is an identification tool based on a series of choices between alternative characters (dichotomous = divided into two parts). Thus, there is no room for subjective observation that may lead to another result. If the morphological traits of the organism are correctly identified, the the result should always be the same. Any differences occur due to errors on the scientist's part.

Proteins that are embedded within, and extend across, the phospholipid bilayer are called _____ proteins. rev: 02_22_2014_qc_455
brilliants [131]

Proteins that are embedded within, and extend across, the phospholipid bilayer are called <u>Integral Protein</u>.

Integral Protein- Any protein containing a unique functional area for the purpose of ensuring its location within the cellular membrane is referred to as an integral protein, which is also referred to as an integral membrane protein. Or, to put it another way, an integral protein seizes the cellular membrane.

Cellular membrane- All cells have a cell membrane, also known as a plasma membrane, which divides the inside of the cell from the external environment. A semipermeable lipid bilayer makes up the cell membrane. The movement of materials into and out of the cell is controlled by the cell membrane.

Jill is heterozygous for gene A and is going to have a child with Jack, who is homozygous recessive for gene A. Which of the fol
Igoryamba

Answer:

D. Aa

Explanation:

Given:

Jill (mother) is heterozygous for gene A --------- i.e Jill = Aa

Jack (father) who is homozygous recessive for gene A-------- i.e Jack = aa

Now if both cross and fertilization occurs, we have:

         A          a

a        Aa        aa

a        Aa        aa

The offsprings are (Aa, Aa, aa, aa)

Nondsijunction is the inability of homologous chromosomes to seperate properly during cell division. Now, we were told that this fertilization undergone nondisjunction in meiosis 1. Hence, both homologous chromosome move into the same daughter cells instead of different daughter cells because separation of homologous chromosome does not occur properly.

Therefore the result of these fertilization of a normal haploid sperm with an egg that had undergone nondisjunction in meiosis yields offspring with genotype Aa of their Mother (Jill).
