Answer:An organism with a cell wall would most likely be unable to take in materials like food via phagocytosis because their cell wall is inhibiting that change in cellular structure.
The answer is chicken.
Biuret test is used to detect the presence of peptide bonds. Peptide bonds exist in proteins, so when they are present the test comes purple(positive).
Protein is found in big amouts in meat, fish and tofu.
From the options the one with the biggest amount of protein is chicken(around 33g/100g) and will cause the highest positive reaction in the biuret test.
Coconut and potato also have it, but its very little. They are rich in other macronutrients.
Cookies are full of sugar, not protein.
Butter is a source of fat, not protein.
Answer:
The event that could not be caused by a population bottleneck is increased population size.
Explanation:
Population bottleneck (genetic bottleneck) is a phenomenon that causes a sharp reduction in population size. It is caused by various factors like environmental disasters such as disease, famines, earthquakes, floods, etc or human activities like hunting, genocide, destruction of habitat, etc. These factors reduce the genetic variation in a population and cause smaller genetic diversity in a smaller population. This causes a change in allele frequency (genetic drift) and it leads to loss of alleles. The effects of genetic drift are stronger in smaller populations than large ones. The small population size increases the chances of inbreeding, accumulation of harmful mutations and genetic homogeneity which leads to inbreeding depression.
An example of a population bottleneck is Cheetahs, which suffers a reduction in genetic diversity during their bottleneck. As a result, they have problems in their reproduction and are highly susceptible to diseases.
D.
Glucose is energy, which means it breaks down when energy is consumed. When a fox consumes it's pray, a seagull glides trough the air and a duck rests on a pond, not much glucose is consumed.
Energy is used when physical effort is necessary, and running from a predator, requires a lot of energy.
