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.
Answer:
Option B
Explanation:
b.The closer an electron is from the nucleus, the greater its energy.
The answer is Option B) The closer an electron is to the nucleus, the greater its energy.
What takes place to the electricity of an electron as it goes closer to the nucleus?Electrons at lower power stages, which might be toward the nucleus, have less electricity. At the lowest strength stage, which has the least electricity, there's just one orbital, so this energy degree has most of two electrons. Most effective, while a decreased electricity level is complete, are electrons brought to the next better strength stage.
The energies of electrons (power degrees) in an atom are quantized, defined through quantum numbers: integer numbers having the most effective unique allowed value and used to characterize the arrangement of electrons in an atom. An electron's electricity increases with increasing distance from the nucleus.

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 ________.
Answer:
Cell Adhesion Molecules (CAMs)
Explanation:
took the test
These proteins will bind to moving white blood cells, transporting them to the location of the infection or damage. These glycoproteins would best be described as cell adhesion molecules.
What are cell adhesion molecules (CAMs)?Chemical signals that alter the plasma membrane of the cells that line the adjacent blood arteries may be released when tissues are wounded or diseased. These blood vessel cells (endothelial cells) respond to the chemical signals by outwardly exhibiting a particular class of glycoproteins.
The sort of protein molecules known as cell adhesion molecules may be found on the surface of cells and are involved in the process of cell attachment.
The intracellular, extracellular, and transmembrane domains of molecules make up single-pass transmembrane receptors.
Therefore, these glycoproteins would best be described as cell adhesion molecules.

In the ocean, there are small fish that live in and around the mouths of large sharks. The shark does not harm the fish because the fish pick food from between the shark's teeth. In return the small fish
symbiosis exists between the sharks and the small fish?
o commensalism
mutualism
parasitism
predation
Answer:
commensalism
Explanation:
Elicit from students that the shark and the remoras, the smaller fish below the shark, have a symbiotic relationship called commensalism, where the remoras benefit from holding onto the shark, but neither species is harmed.

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,
Herbivores have more available energy and are at a lower trophic level because they receive energy directly from producers in the Food chain. So, the correct option is A.
What is Food chain?A food chain is defined as a linear network of links in a food web that begins with producer organisms and ends at apex predator species, detritivores or decomposer species. It also refers to how organisms are related to each other through the food they eat where each level of the food chain represents a different trophic level.
Producers have 100% of the energy that is derived from the Sun, the next level would receive 10% of it, so herbivores would have a 10% energy level, followed by carnivores at 0.1% and after this another higher trophic level is 0.01%. Herbivores have more available energy and are at a lower trophic level because they obtain energy directly from producers in the food chain.
Therefore, the correct option is A.
