Herbivores and carnivores are both types of consumers in a food web but they are on different trophic levels. Why are herbivores and carnivores on different trophic leves
оооо
Herbivores have more available energy and are at a lower trophic level because they receive energy directly from producers.
Carnivores have more available energy and are at a lower trophic level because they receive energy directly from producers.
Herbivores have more available energy and are at a higher trophic level because they receive energy directly from carnivores
o Carnivores have more available energy and are at a higher trophic level because they receive energy directly from herbivores,

How does the energy of an electron relate with the distance from the nucleus?


a. The closer a proton is from the nucleus, the greater the electron's energy.

b. The closer an electron is from the nucleus, the greater its energy.

c. The farther a proton is from the nucleus, the greater the electron's energy.

d. The farther an electron is from the nucleus, the greater its energy.

e. The closer a neutron is from the nucleus, the greater the electron's energy.

The diagram below shows the branching tree diagram for humans. The text box below it shows the set of derived shared characteristics for the branching tree. . Look at the possible derived shared characteristics, shown in the text box. Think about where these should be placed along the branching tree diagram. Where in the branching tree would you most likely write "lives on land during all life stages"? Explain your answer.

When tissues are injured or infected, chemical signals can be releases that affect the plasma membrane of cells that line the nearby blood vessels. These blood vessels cells (endothelial cells) respond to the chemical signals by displaying a type of glycoproteins on their surface. These proteins will attach to circulating white blood cells bringing them to the site of injury or infection. These glycoproteins would best be described as ________.
