I would say (A) because it allows the bacteria (bacteria X) to be exposed to the control condition and the experimental condition so that a cause-effect relationship can be established. Here, the control condition would be the darkened area and the experimental condition would be the lightened area.
Answer:
Regarding wild boar, the fact that is best supported by the evidence provided is wild boars have established successfully mostly in areas with warm climates.
Explanation:
The wild boar (Sus scrofa) is a mammal from Africa, whose capacity to adapt to the environment is high. However, it is usually found in warm climates where it has a good supply of water and food.
According to the description of its distribution on the map, the states where it is found —predominantly Texas, California and Florida— verify the fact that they can be found mostly in warm climates, where they have found an ideal environment for their development..
About the other options:
- <u><em>Wild boars were brought to the United States by humans</em></u><em>. This is true, but it is not a fact that can be deduced from the information on the map.</em>
- <u><em>Wild boars have quickly spread through the United States</em></u><em>. The map does not show this information.</em>
- <u><em>Wild boars have a high reproductive rate and no natural predators</em></u><em>. The map does not show this information.</em>
The post mortem interval of a body enclosed in a plastic bag could be best estimated by the insects found in the body, in that case forensic science need to listen to what those little creatures have to say, insects could tell if the body has been moved from the crime scene, how long it´s been in an specific place, and how long it´s been since death until found, every group of insects can tell something different, from worms, arachnids to flyes, each one of them has a time to get into the body, so it could tell you for how long it´s been dead.
Answer:
C. Genetic material composed of nucleic acid
Explanation:
The information needed by every organism to perform life functions like reproduction, growth etc are held in the genetic material that the organism carries in its genome. Every genetic material of organisms is composed of nucleic acids, which are only two in nature i.e. Ribonucleic acid (RNA) and Deoxyribonucleic acid (DNA). This is a common feature of all organisms including bacteria and viruses that they contain genetic material which must be in form of a nucleic acid.
The viruses do not undergo a cell division, neither do they contain protein synthesis structures called Ribosomes because they do not have the ability to reproduce or perform any living process outside a living host cell. This means that they strictly depend on another organism's transcriptional, translational, replicational ability to survive.
Percent error is calculated by the expression:
%error = |actual value - observed value| / actual value x 100
We calculate the error of the values as follows:
<span>a. 23.487 cm
% error = |</span><span>23.490 - 23.487| / 23.490 x 100 = 0.013%
</span><span>
b. 23.493 cm
</span>% error = |23.490 - 23.493| / 23.490 x 100 = 0.013%
<span>
c. 23.516 cm
</span>% error = |23.490 - 23.516| / 23.490 x 100 = 0.11%<span>
d. 23.501 cm
</span>% error = |23.490 - 23.501| / 23.490 x 100 = 0.05%<span>
e. 23.477 cm
</span>% error = |23.490 - 23.477| / 23.490 x 100 = 0.055%
