B. they are single molecules...
Answer:
WAVE #3
Explanation:
Radio waves have the longest wavelengths in the EM spectrum, according to NASA, ranging from about 0.04 inches (1 millimeter) to more than 62 miles (100 kilometers). They also have the lowest frequencies, from about 3,000 cycles per second, or 3 kilohertz, up to about 300 billion hertz, or 300 gigahertz
Both plant and animal cells have a nucleus and mitochondria
Answer:
C. They have a greater surface-to-volume ratio.
Explanation:
Because these smaller cells can access and pass through the membranes of the other cell membranes and permeable coverings easily and voluntarily unlike larger cells. It is also efficient for these smaller cells to penetrate and travel, delivering and transporting goods and materials such as nutrients, oxygen and waste throughout the body without consuming enough energy and conserving lesser space.
For simple reasons, they are faster, more efficient and consumes little space, and most especially depletes lesser energy. So, many small cells have more surface area than one large cell.
1) Amino acids. Option B.
2) Phosphorus. Option D.
<h3>What are proteins?</h3>
Proteins are macromolecules made up of 2 or more amino acid units linked together by peptide bonds.
According to the passage, antibiotics work by breaking down the cell water proteins of bacteria. When proteins are broken down, they are broken into their component amino acids.
Therefore, when the researchers examine the phagocyte, the presence of amino acids would be an indication of the effectiveness of the antibiotics.
Amino acids are made up of elements such as nitrogen, carbon, oxygen, and hydrogen. Thus, if the researchers examine the monomers present in the phagocytes, all these elements should be found. Except for phosphorus.
