Ice floats because _____. A.it is a solid B.it is less dense than liquid water

Biology

matrenka [14]2 years ago

Answer: Option B

Explanation:

Ice is the solid form of water, and its density is less than the density of water. This is the reason why ice floats on water.

Density of water is more and ice is less so ice floats on water. This property of  ice helps the plants and animals living in the colder regions.

This is the reason why the water beneath ice has optimum temperature and plants and animals live inside it without being freezed.

In the spleen, ___________ from red blood cells is broken down to form (unconjugated) bilirubin. Unconjugated bilirubin is insol
adelina 88 [10]

Answer:

Haemoglobin; liver; binds; stored; bile duct; small intestine; lipids.

Explanation:

Serology can be defined as the study of blood and the reactions between antibodies and antigens in the blood.

In Biology, blood pH can be defined as a measure of the hydrogen ion (H¯) concentration of blood i.e the level of alkalinity or acidity of blood.

Basically, the normal blood pH of a human being should be between 7.35 and 7.45.

Hence, one of the ways in which the body regulates blood pH is with proteins. Proteins help regulate blood pH by accepting and releasing hydrogen ions. Typically, when the blood pH falls, the hydrogen ions (H¯) are accepted (absorbed) while hydrogen ions are released when the blood pH rises.

For example, a protein such as haemoglobin which makes up a composition of the red blood cells, binds an amount of acid required to regulate blood pH.

In the spleen, haemoglobin from red blood cells is broken down to form (unconjugated) bilirubin. Unconjugated bilirubin is insoluble in blood plasma so binds to albumens in the blood and is sent to the liver. Bilirubin binds with glucuronic acid to form conjugated bilirubin. It forms part of the bile, which is stored in the gall bladder. Food in the gut stimulates gall bladder contraction and the bile passes down the bile duct to the small intestine, where it aids in the digestion of lipids.

Using the information from problem 11, scientists do a further test cross using a heterozygote for height and nose morphology. T
mote1985 [20]

Answer:

The recombinant frequency between T and S is  18%;

The correct Sequence of genes is T-A-S

Explanation:

The table below shows the recombinant frequency between heterozygous height and nose morphology:

Tall-uptrend snout                            40%                            Expected

Dwarf-downtrend snout                   42%                            Expected

Dwarf-uptrend snout                         9%                             Recombinant

Tall-uptrend snout                             9%                             Recombinant

Sum Total                                           100%

To calculate the recombinant frequency; we have :

=9+9

=18%

Hence, the recombinant frequency between T and S = 18%

The determinant of the corect sequence of the genes is  T-A-S
