Answer;

Waxes forms protective layers on plants and animals that repel water. beeswax, birds feathers, carnauba wax, jojoba oil, lanolin.

Explanation;

-Waxes are nonpolar lipids that form protective layers on plants and animals. For example, waxes cover the feathers of some aquatic birds to keep the feathers dry. On the other hand, plants often have leaves coated with waxes to prevent water from evaporating off the plant surface.

-Because of their hydrophobic nature, waxes prevent water from sticking on the surface of these structures.

The water repellant properties of waxes is very useful in the leaves of some plants, in the feathers of birds and also in cuticle of insects. Waxes in plant leaves reduce the amount of water that is lost by the leaves. The wax that is present in the birds' feather prevent them from getting wet with water.

What can gene therapies potentially do to treat cystic fibrosis?
Lera25 [3.4K]

Answer:

The correct answer is B make cells produce a functional CFTR protein.

Explanation:

Cystic fibrosis is a disease that is caused due to the mutation in the transmembrane protein known as cystic fibrosis trans membrane conductance regulator or CFTR. Cystic fibrosis trans membrane regulator proteins helps in the formation of thin mucus and due to the mutation in CFTR the mucus becomes thick.The disease cystic fibrosis basically affect the respiratory system.

 If gene therapy is used to treat cystic fibrosis then it can replace the mutated CFTR gene with a functional one so that the cell containing CFTR gene can produce functional CFTR protein.

How are the hardy-weinberg principles used in the analysis of codis genotypes and other strp-locus comparisons?
lana66690 [7]
<span>HWE is used with COIDS and non CODIS eligible DNA profiles to provide statistical caluclations for the rarity or uniqueness of profiles. Each STR kit test for a certian number of loci. Each lous has a set ladder of observed alleles. Each of these alleles has value for its observed frequency in a population. It is the rarity of each allele at each location that will give you the value for rarity of the profile as a whole. This rarity fo the profile is calucalted in CODIS under certian circumstances using to determine the eligibilty of a partial profile or a forensic mixture to determine its eligiblity for the different leves of the database.</span>

Y-purple while y-white

YY is the genotype of a pure breed purple flowered pea plant

Yy is the genotype of a heterozygous pea plant flower (purple is dominant over white)

yy is the genotype of a white flowered pea plant that is generally called as recessive

Which letter in Figure 1 represents meiosis? Why?
SSSSS [86.1K]

The letter D in Figure 1 represents meiosis, while letter A represents mitosis. Meiosis is a reductional cell division.

Mitosis is a type of cell division where a parent cell divides to produce two genetically identical daughter cells (in this case, diploid cells).

Meiosis is a reductional cell division where a parent cell divides twice to produce four daughter cells having half of the genetic material.

Meiosis occurs in germinal cells, while mitosis occurs in somatic (body) cells.

Schach [20]

Answer:

Zooplankton

Explanation:

The correct answer here would be the zooplankton. (see the attached image)

<em>Due to the important position of the Zooplankton in the food web, any change in the environment that removes them will cause the most instability in the ecosystem. </em>

<em>Five different organisms within the food web directly depend on the zooplankton for their food four of which have no any other option. Removal of zooplanktons from the environment will directly affect these organisms and this will throw the entire food web into disarray.</em>
