Carbon dioxide is added to the atmosphere naturally when organisms respire or decompose (decay, or release gas), carbonate rocks are weathered, forest fires occur, and volcanoes erupt. Carbon dioxide is also added to the atmosphere through human activities, such as the burning of fossil fuels and forests and the production of cement. Which this also adds to the temperature increase around the world due to our atmosphere keeping all of this CO2.

Explain what happens to an animal cell when it removed from an organism and placed into distilled water

Answers

Answer:

I think it has to do with osmosis

Explanation:

Osmosis is the process of having water pass from a low concentration medium to a high concentration one, given that the barrier (membrane) is semi-permeable.

When a cell is placed into distilled water, hypertonic solution takes place.

A cell may contain many solutes so it is considered hypertonic when compared to distilled water which is hypotonic So in this case, when a cell is placed in distilled water, water moves from outside of the cell to the inside leading to swelling of the cell.

The H substance is needed for the proper phenotypic expression of the A, B, and AB blood types in the ABO blood typing system in humans. Individuals who are recessive for the H substance (hh) will have a type O phenotype, even if they have the A and/or B alleles. Two individuals, each with type AB blood and heterozygous at the H locus have children. What is the probability they will have a child who is phenotypically type O?

Answers

Answer:

The correct answer is - 4/16.

Explanation:

In this question, it is stated that in ABO blood system the proper phenotypic expression of A, B, AB blood types needs H substance. If an individual has recessive for the H substance (hh) will have a type O phenotype.

The cross: ABHh and ABHh

gametes: two set of AH, BH, Ah, Bh

Punnett:

         AH         BH          Ah          Bh

AH    AAHH   ABHH     AAHh     ABHh

BH    ABHH   BBHH     ABHh     BBHh

Ah    AAHh    ABHh     AAhh      ABhh

Bh    ABHh    BBHh     ABhh      BBhh

As shown there is only 4 out of 16 offspring are recessive for H substance therefore, only 4/16 will have O blood group
