1. Reduces the chromosome number from diploid to haploid
2. Ensures that each of the 4 gametes has a complete set of chromosomes
As the ribosome reads each codon of mRNA, it directs tRNA to bring the specified amino acid into the ribosome. Each tRNA molecule carries<span> just one kind of amino acid. In addition, each tRNA molecule has </span>three unpaired bases<span>, </span>collectively called the anticodon<span>—which is complementary to one mRNA codon.</span>
Answer:
Immune
Explanation:
The immune system helps to protect our body from all sort of organisms ranging from invading toxins and micro-organisms which negatively affects an individual’s health and well being.
Stress has an adverse effect on the immune system such that it weakens and suppresses the functions of the required antibodies in the body system. This is the reason why many aged people fall sick because they have gone through more stress when compared to younger people.
Quality of light is the limiting factor restricting phytoplankton to approximately the top ten feet of the ocean, rather than deeper
Explanation:
When sun rays pass through the water in the oceans, they are quickly diffused and cannot penetrate very deep into the deep water layers. Remember that phytoplanktons are photosynthetic organisms and hence require sunlight to manufacture their own food. They, therefore, cannot grwo in deeper layers of the oceans. They are only found in the photic zone.
The quality of light is especially of most importance and hence the major limiting factor. Red light, of longer wavelength, and which is the major wavelength of light that is used the most by photosynthetic organisms, diffuses very fast than blue light when it passes through water. Therefore the more reason phytoplankton is found in the top ten feet of the ocean, rather than deeper.

Answer:
Explanation:
Wood has_chemical energy_____ energy while a burning fire has__heat energy __ energy
Wood is a material that makes up the central part of the trunk and branches of trees. Wood is made up of complex hydrocarbons and a rich cellulose network of organic molecules. A wood stores chemicals energy.
Combustion process such as burning liberates heat energy in them. Burning occurs in the presence of oxygen. As the oxygen combines with the materials, heat becomes liberated to the surroundings. Burning is an exothermic process in which heat energy is liberated.
