Yeah!! As it acts in slightly acidic medium i.e., of pH 6.8 so, acidic conditions deactivate amylase enzyme...

Answer:

The correct answer would be "yes, acidic environment decreases or deactivates the amylase enzyme".

Amylase refers to the class of enzymes which are involved in the hydrolysis of sugars (polysaccharides).

For example, salivary amylase and pancreatic amylase hydrolyze the starch into di and trisaccharides.

In addition, the amylase present in the human physiology (alpha amylase) has the optimum pH of 6.7-7.0 and thus, this amylase would get deactivated in acidic or low pH conditions.

This is why the pH of the intestine is slightly basic which complements the functioning of the pancreatic amylase.

The acidic medium can cause the denaturation of the enzyme and thus, results in the deactivation of the enzyme.

The fraction of offspring with black coat color and straight fur is 9/16.

Explanation:

Information given:

black coat colour and straight fur - dominant genotype BBCC, BbCc

yellow coat colour and curly fur - recessive genotype bbcc

Both the traits are independently assorted. The fur colour and fur type is not present on the same chromosome and are not sex linked.

The genotype of the parents are:

BbCc X BbCc

Punnet square shows:

BC Bc bC bc

BC BBCC BBCc BbCC BbCc

Bc BBCc BBcc BbCc Bbcc

bC BbCC BbCc bbCC bbCc

bc BbCc Bbcc bbCc bbcc

9 BLACK STRAIGHT

3 BLACK CURLY

3 YELLOW STRAIGHT

1 YELLOW CURLY

9/16 is the fraction of progeny to be black coat colour and straight fur.

If 32 packed volume units of cells are separated from 46 volume units of plasma from a blood sample, the haematocrit is _______

nordsb [41]

Answer:

If 32 packed volume units of cells are separated from 46 volume units of plasma from a blood sample, the hematocrit is 41,02% percent. The hematocrit value is within the normal range.

Explanation:

Hello!

Hematocrit (or packed cell volume -PCV-)is defined as the percentage of red blood cells (vol%) in a blood sample. One common method of determining it is by centrifuging a heparinized blood sample in a capillary tube at 10 000 RPM for five minutes. This separates the blood sample in two layers, formed elements (RBC and WBC) and Plasma.

The length of the layers is directly measured from the tube and represents the volume of packed cells and plasma. Since the number of white cells is negligible compared to the number of red cells, the formed elements are considered to represent the red blood cells.

The hematocrit can be calculated as the volume of packed cells divided by the total volume of the blood sample.

$\frac{PCV}{TOTAL(pcv+plasma} * 100$

In the question:

$\frac{32}{32+46} * 100$ = $\frac{32}{78} * 100$ = 41,02%

In humans the normal hematocrit range is 40,7% to 50,3% for men and 36,1% to 44,3%. Taking these reference values into consideration, this sample is within the normal range.

I hope you have a SUPER day!

expeople1 [14]

Answer:

In the presence of oxygen, respiration of yeast produces carbon dioxide and water. In the absence of oxygen, respiration of yeast produces carbon dioxide and alcohol.

Under the assumption that the yeast has insufficient exposure to oxygen in the surrounding air in the testtube, alcohol and carbon dioxide would be expected to be found in the test tube
