The answer is B Troposphere. The Troposphere is actually the lowest layer of atmosphere on the earth. The Lithosphere is the upper area of the Earth's solid layers.
Energy is usually related to the metabolic processes of living organisms in its organic form.
Many cellular processes require a steady supply of energy provided by the cell’s metabolism. Signaling molecules such as hormones and neurotransmitters must be synthesized and then transported between cells. Pathogenic bacteria and viruses are ingested and broken down by cells. Cells must also export waste and toxins to stay healthy, and many cells must swim or move surrounding materials via the beating motion of cellular appendages like cilia and flagella.
Answer:
The correct answer is option d. "Its conformation will change when both an ion and a small molecule bind to it".
Explanation:
The secondary active transport is a form of active transport at which a ion (typically Na+ or H+) is transferred down its electrochemical gradient to the uphill movement of another molecule. Secondary active transport takes place by the conjunctive work of membrane-bound proteins and sodium–potassium pumps. During secondary active transport, both of these proteins change its conformation when an ion and a small molecule bind to it. This change in conformation makes possible that the ions and the small molecules pass through the membrane.
Answer:
Noble Gases.
Explanation:
The reason why I say this is due to them having eight valence electrons, their outer energy levels are full.
Good define unemployment as having no job teheheheh
