Hi there!
Your answer would be
C. Observation, hypothesis, experiment, and conclusion.
Hope this helped and please give brainliest!!
Wave of option A has the highest frequency.
Option A.
<h3><u>Explanation:</u></h3>
Frequency is defined as the total number of complete waves in an unit time. A complete wave consists of a complete cycle of the amplitudes of waves.
In all the figures, we see transverse waves. They have the mean position denoted by a straight line, and the waves do oscillate up and down to complete a full cycle. The most number of waves in a given time has the highest frequency. If we count the full number of waves in the particular given time, Wave A has 5.75 complete waves, wave B has 3.5 complete waves, wave C has 2 complete waves and the wave D has 2.75 complete waves. So the wave A has highest number of complete oscillations in a given time. So wave A has highest frequency.
The answer is B, fossil fuels take a long time to form and humans use lots of them everyday
Answer: urea disposal
Explanation:
<u>The liver, which is the largest organ in the human body, performs three vital functions of the organism: detoxification, synthesis and storage. </u>
The liver acts as an authentic filter that collects and eliminates numerous toxins, such as ammonia, or toxins that we ingest, such as alcohol (it performs a biotransformation of toxins). Our liver is also responsible for the metabolism of carbohydrates, lipids and proteins, secreting bile, an essential element for the digestion. It also prevents bleeding through a coagulation process. And it is a container of vitamins (A, D, E, K) and glycogen (carbohydrates), while energy is stored in the form of sugar, made available to our organization.
The urea cycle takes place primarily in the liver. Organisms convert ammonia to a less toxic substance, such as urea, via the urea cycle. <u>Then it is released into the bloodstream where it travels to the kidneys and is ultimately excreted in urine. </u>
So, the liver is involved in the production of urea, but the kidney is responsible of its disposal.
