Formation of island chains occurs when convergent boundaries interact and is denoted as option A.
<h3>What is Convergent boundary?</h3>
This refers to an area where two or more lithospheric plates collide in the earth.
When the y interact, island chains are formed which consists of sea with sparse islands around the area.

The correct answer is option B, that is, they all use cellular respiration to obtain energy.
Cellular respiration refers to a set of metabolic procedures and reactions, which occur in the cells of species to transform biochemical energy into ATP and then discharge waste products. The reactions taking place in respiration are catabolic, that is, dissociation of bigger molecules into smaller ones, and in the process liberating energy.
The nutrients, which are generally utilized by plant and animal cells in the process of respiration are amino acids, sugar, and fatty acids, and the most usual oxidizing agent, that is, the electron acceptor is the molecular oxygen.
The correct answer is d: '<span>the protective coats of both groups are made of chitin'
Chitin is </span><span>a long-chain </span>polymer <span>derivative of </span>glucose, with a structural function in various groups of animals and plants, such as <span>of </span>cell walls<span> of </span>fungi<span>, </span>exoskeletons<span> of </span>arthropods <span>and the scales of </span>fish. It can be compared in function to keratin found in our hair and nails.
Answer:
Pacific Northwest
Explanation:
In the United States, the Pacific Northwest is the region that receives the least thunderstorm in a year. This is because of the location of the region. The region consists of states like Washington, California, Alaska, Hawaii, and Oregon. This region has few thunderstorms due to the nature of the region. The coldness of the pacific ocean means that there is more colder air on the earth. This suppressed the hot air. Thus, conventional rainfall; with thunder is less common. The other factor is the dryness of the region. The dry region has a lower humidity. This lesson the chance of charges air between the two fronts.
<span>Hersey and Chase labeled the outer protein coat of a bacteriophage with radioactive sulfur, and the inner DNA with radioactive phosphorous. After allowing the bacteriophage to infect E.coli bacterium and undergoing a heavy blender process, the empty "ghost" phages were separated from the bacteria. The infected E.coli were positive for radioactive phosphorous, indicated that DNA was the genetic material inserted from the bacteriophage. The radioactive sulfur was not present in the infected bacteria, indicating that protein was not the genetic material.</span>
