After you set up a fish tank, you are sure to see algae growing in it. There is plenty of light, fertilizer in the form of fish droppings, and plants or glass for algae to cling to. You may see green strings of algae in the water or green spots growing on the glass. Your whole aquarium can turn green if you don’t stop the algae. To prevent the problem, you can add algae-eating fish or microorganisms to the water. Covering the aquarium for a few days will also kill algae, which need photosynthesis to survive.

Multi-celled algae grow into larger organisms through cell division. For one-celled algae, the purpose of cell division is

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 ________.

Answers

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.

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,

Answers

The answer is D carnivores eat 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.
