Answer:

C.After several generations, this trait is likely to be much more

common because individuals with the trait will have a greater

chance of passing it on to their offspring

Explanation:

The mutation makes the squirrels have higher camoflauge skills and not as easily spotted to predators, making their life expectancy higher, then they have a higher chance of having children with that mutation.

Answer:

in a certain population of red squirrele, a mutation causes several squirrels to

be bom with darker coats. These coats make the squirrels nearly inweible

when they are foraging on the forest floor , According to the theory of evolution by natural selection, what is likely to happen to this trait after several generations?

After several generations, this trait is likely to be much more common because individuals with the trait will have a greater chance of passing it on to their offspring,

Explanation:

It would later turn to what is termed as germline mutation which are mutations passed from parent to offspring, as time progresses the trait would be more and increases the chance of being transferred to their offspring

because a monoglyceride molecule has more carbon atoms than a glucose molecule, you can assume that...

Alexxandr [17]

The monoglyceride molecule contain more energy than a glucose molecule because monoglyceride requires more oxygen for each carbon atom because there are more electrons surrounding each carbon in monoglyceride. Therefore, to oxidize monoglyceride more oxygen having high affinity for electrons, are required. Thus, monoglyceride produces more energy.

Louis Pasture determined that microbes only appeared in sterile broth if the broth was exposed to the air. He concluded that mic

Norma-Jean [14]

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:

a and c. All animals are made of cells and cell is the basic functional unit of living things are postulates of the cellular theory that were not demonstrated by Pasteur's experiment.

d. Unicellular organisms inherit an exact copy of DNA from the parent cell is not a postulate of cell theory.

What are the parent genotypes

Andre45 [30]

Answer:

A dominant allele is denoted by a capital letter (A versus a).Since each parent provides one allele, the possible combinations are: AA, Aa, and aa. Offspring whose genotype is either AA or Aa will have the dominant trait expressed phenotypically, while aa individuals express the recessive trait.
