Answer:
50%
Explanation:
The pink flower donates the r allele and produces pink flowers in 50% of the offspring.
"resting membrane potential"
Resting potential occurs when membrane potential isn't altered by action potentials. When a membrane is polarised and there's no sinaptic potentials or any other active change of the membrane potential we are before a resting membrane potential.
Explanation:
A protein is a linear molecule comprised of amino acids.The sequence of a protein's amino acids is determined by the sequence of bases in the DNA coding for the synthesis of this protein.
Answer:
the law of segregation the alleles segerate into gametes : when gametes are formed, each allele of one parent segregates randomly into the gametes, such that half of the parents gametes carry each allele

Explanation:
Answer:
Louis Pasteur, by observing that the microbes were in the air and contaminated the broth helped determine that all the cells came from pre-existing cells (option b), one of the postulates of the cell theory.
Explanation:
Louis Pasteur's experiments, conducted around 1860, showed that unicellular organisms appeared in a culture broth only if it was exposed to the air, where other microorganisms were present, thus disproving the hypothesis of spontaneous generation.
On the other hand, in the broth that was not exposed to the air Pasteur did not observe microorganisms.
By rejecting the hypothesis of spontaneous generation through his experiment, Louis Pasteur reaffirmed the postulate of the cell theory that proposes that all cells come from preexisting cells.
The other options are not correct due to:
<em> a and c. </em><em><u>All animals are made of cells
</u></em><em> and </em><em><u>cell is the basic functional unit of living things</u></em><em> are postulates of the cellular theory that were not demonstrated by Pasteur's experiment.</em>
<em> d. </em><em><u>Unicellular organisms inherit an exact copy of DNA from the parent cell</u></em><em> is not a postulate of cell theory.</em>
