What would you observe if you decolorized your slide too much? how would your cells appear?
iren2701 [21]
<span>It would depend on the method of decolorization. The most common one is by using Acetone-alcohol. When your slide are decolorized too much with Acetone-alcohol, cells will appear to be pink since the crystal violet are washed out.</span>

What do you think would happen if a genetic mutation caused a person's digestive tract to have stratified columnar epithelium in
Eddi Din [679]

Answer:

Absorption and secretion would be impossible within the digestive tract.

Explanation:

Epithelium is one of the tissues found in humans. It is classified as either simple or stratified depending on the number of cell layers. Simple epithelial tissues have one layer of cells while stratified have many layers of cells. Based on the shape, epithelial tissues can either be squamous, columnar or cuboidal.

Due to the single-layer of the simple epithelial tissues, they line the walls of secretory or absorptive organs e.g organs of digestive tract. The stratified epithelium is majorly for protective function due to the number of cell layers it possess and not a good type of epithelium for locations where absorption and secretion of substances is common e.g digestive tract.

Hence, if a genetic mutation causes a person's digestive tract to have stratified columnar epithelium instead of simple columnar epithelium, ABSORPTION AND SECRETION of chemical substances, which is a key feature of organs (stomach, intestine) that make up digestive tracts, will be impossible.

Why is salivary amylase active for only an hour or so, whereas lingual lipase isn't active until reaching the stomach
leva [86]

Salivary amylase will be active for only an hour or so because the optimum pH for activity of amylase is about 6.7–7.0 which is available in the mouth but the pH of the stomach is acidic around 1-2 due to which the amylase enzyme becomes inactive in short-time.

The lingual lipase enzyme is present in the saliva but isn't active until reaching the stomach because this enzyme is acid stable and works efficiently in the stomach, not in the mouth.

Amylase enzyme is secreted in the mouth and is responsible for the breakdown of starch in food into sugars and it starts acting as soon as we put food in the mouth whereas Lingual lipase enzyme is secreted along with saliva but it is not active in the mouth rather its activity starts in the stomach which is responsible for the degradation of triacylglycerol molecules.

A female fly is heterozygous for three X-linked genes. The dominant alleles are ABC and the recessive alleles are abc. She is cr
telo118 [61]

Answer:

<h2>(14+16)/1000 *100= 3</h2>

Explanation:

Parental combinations are always more common then other recombinant progenies.

A female fly is heterozygous for three X-linked genes crossed with an abc/Y male. . If single crossover occurs between a & b  and between b & c, then the double cross is that, which occurs in both.

Double cross over progeny are always least in number, so here double cross occurs are in abC 14 and ABc 16.

So we are expecting that number of double cross over progeny= (14+16)/1000 *100= 3
