Answer:

D. the top carnivore in a food web

Explanation:

In any ecosystem food chain is not operates in isolation. Different food chains are in operation at a time. The organisms of different food chains are interlinked. The network of different food chains in an ecosystem is called food web.  

The top carnivores in a food web are the apex predators. They can obtain food from the primary, secondary or tertiary consumers of different food chains. They are not dependent on the consumers of one food chain.  

It is, therefore, the top carnivores are the top consumers and are most likely to survive.

The papillary muscles contract after the other ventricular muscles so that they can take up the slack on the chordae tendineae b
sashaice [31]

Answer:

False

Explanation:

The papillary muscles of both right and left ventricles began to contract shortly before the other ventricular muscles (systole) so that they can take up the slack on the chordae tendineae as the full force of ventricular contractions sends blood against the atrioventricular (AV) valve flaps.

They prevent the backward flow of blood to atria from ventricles. So if they contract after the ventricle systole they would not be able to perform their job.

identify a probable reason that the dark moths survived while the light moths did not during the industrial revolution
nignag [31]

Answer:

directional selection

Explanation:

The directional selection is a type of Darwinian selection where a particular phenotype is favored in the population, thereby modifying the allelic frequencies to increase the proportion of the favored phenotype. <em>Biston betularia</em>, also known as peppered moth, is a species that was influenced by directional selection in its recent past. Before the industrial revolution, the frequency of light-colored moths was predominant compared to the darker-colored phenotypes, because this color has higher adaptive fitness in a clean, no pollution environment, thereby light-colored moths were able to avoid predatory birds. However, during the industrial revolution, the frequency of dark-colored moths increased in response to pollution (i.e. darker environment), thereby conferring a higher adaptive fitness to darker phenotypes.

Answer;

-Enzymes

Enzymes are class of proteins, they make metabolic reactions proceed much faster than they would have on their own.

Explanation;

-Proteins are biological macromolecules that are diverse in shape size and function. Enzymes are biological molecules (proteins) that act as catalysts and help complex reactions occur everywhere in life. They are biological catalysts.

All enzymes are proteins by definition. But not all biomolecular catalysts are proteins. Most enzymes are proteins, although a few are catalytic RNA molecules.
