The composition of the hair shaft onto which shampoos and conditioners are applied are; keratin, water, lipids, minerals, and pigments (melanin).

The hair shaft is a part of the hair that is situated above the skin. The hair shaft is mostly composed of keratin with water, lipids, minerals and pigments (melanin). The hair shaft contains three layers which are; the cuticle (the thin outer part of the hair shaft), the cortex (the middle part of the hair shaft which is responsible for the texture, strength, and colour of the hair), and the medulla (the deepest part of the hair shaft). The cuticle is the first layer of the hair shaft to be damaged when hair is not treated properly through the use of insufficient shampoo, conditioner, or brushing.

Sample could get contaminated with an acid. because vinegar contains acetic acid.Acetic acid is the second simplest carboxylic acid (after formic acid) and consists of two small functional groups, an acetyl group (sometimes symbolized as Ac) and a hydroxyl group (AcOH); it can also be viewed as a methyl group and a carboxyl group linked.

Draw a picture of a cell cycle and describe what is happening in the cell cycle

marysya [2.9K]

The cell cycle or cell-division cycle is the series of events that take place in a cell leading to its division and duplication of its DNA to produce two daughter cells. In bacteria, which lack a cell nucleus, the cell cycle is divided into the B, C, and D periods.

What happens when the sun heats up water in earths surface and turns it into water vapor?

BlackZzzverrR [31]

Answer:

Evaporation – Evaporation happens when heat from the Sun turns liquid water into water vapor (gas). About 90% of the water in the atmosphere comes from evaporation. Most evaporation occurs in the oceans, because they cover so much of Earth's surface. The sweat evaporates into the air.

In corn, the allele A allows the deposition of anthocyanin (blue) pigment in the kernels (seeds), while aa plants have yellow ke

lara31 [8.8K]

Answer:

Explanation:

As given,

Allele A for blue anthocynin.

aa for yellow kernel;

at second locus;

W produce smooth kernel,

ww for wrinkled kernel;

Parents as given are: AaWw and aaww

Progeny are:

blue smooth ( AaWw)= 1447;

blue wrinkle (Aaww)= 169;

yellow smooth (aaWw)= 186;

yellow wirnked (aaww)= 1510

Recombinant progeny are 169+ 186= 355

non- recombinant progeny are = 1447+ 1510= 2957

so recombination frequency (RF)= 346/2957×100= 12.0054%

So a and w are linked genes.

They are 12 mu far away from each other.

b) Blue smooth parent= AaWw.

c) Aaww crossed with aaWw

progeny are= AaWw, Aaww, aaWw, aaww,

They all are produced in same proportion =0.25% or 1/4.
