The first step is to identify the problem. There are factors to consider in keeping a plant or a tree healthy. These include water, oxygen, sunlight, soil, nutrients, climate, and other environmental conditions. If the environment seems to suit the other trees in the garden, ruling out other factors can be useful in determining why only one tree seems to be unhealthy. Once the problem is identified, a scientific investigation must be done to gather data and pieces of evidence which can explain why this event actually occurred. One of the best ways to gather evidence is through observing the tree and checking other signs which might identify if the tree is diseased. Once the gathered data are analyzed and the cause is identified, proceed in thinking of ways on how to solve it. In seeking a solution, it is best to ask information from experts and proper authorities.
Green plants use their chlorophyll to capture the energy of sunlight and split water molecules. As they do, they release oxygen into the air. Green plants use energy from the sunlight and carbon dioxide from the air to make sugar. In effect, they create “mass” from “gas.”
The answer is C. The original population is the dotted line and the population after the selection is the faded blue. The two shell patterns are increasing while the most common was is decreasing.
Like other herpes viruses varicella is an enveloped DNA virus.
<span>Varicella-zoster virus is a type of herpes virus which infect humans also called chickenpox virus, varicella virus, zoster virus, and human herpesvirus type 3 (HHV-3). Its genome is a linear duplex DNA molecule, it multiplies in the lungs and after the primary infection, it goes dormant into neural cells where it can be reactivated and cause neural diseases.</span>
