Answer:
A cell will shrink in a hypertonic solution. In a hypertonic solution, there is more solute outside the cell than inside the cell. This means that water will leave the cell (diffuse) to try and create equilibrium, causing the cell to shrink.
In a diagram, there will be lots of solute outside the cell and less solute inside the cell.
Answer:
Perfectly in theory, except there is chance involved
Explanation:
The Punnet square is a diagram that allows scientists to predict the possible outcomes of the offspring when the genotypes of the parents are known. This is in line with Mendel's principles, and from a theoretical point of view would match up perfectly. However, it all works based on <em>probability</em>.
However, inheritance is always down to chance. Of your parents 2 alleles, you always have 50:50 chance of inheriting one of the allele. Overall, this is what is predicted in punnet squares.
However, think about flipping a coin. There is always 50:50 chance of getting heads, but that doesn't mean it is impossible to flip a coin and get tails 10 x in a row. It is just less likely. So in reality, observations might deviate from the theory.
Answer:
It controls the rate at which chyme enters the small intestine
Explanation:
Cephalic phase is one of the phase of gastric secretion (other two are gastric phase and intestinal phase) that begins even before food enters the oral cavity. Thinking of food stimulates the release of gastric juice via parasympathetic nervous system). Food that enters the stomach also stimulates the secretion of gastric juice by parietal cells. Partially digested food directly activates G cells (Enteroendocrine cells) to secrete gastrin which also stimulates the release of gastric juice.
By definition, if the DNA of a cell undergoes a spontaneous mutation, is not due to <u>exposure to radiation.</u>
<u></u>
Spontaneous mutations are derived from various sources, which include mistakes made all through the replication of undamaged template DNA, mutagenic nucleotide substrates, and endogenous DNA lesions.
Spontaneous mutation, also referred to as background mutation can be defined as genetic modifications that arise inside the absence of mutagens and haven't any recognized reason.
It is able to result from sports of a normal cellular, including mistakes or errors during DNA replication.
