B.)Nuclear energy use can decrease soil quality through waste products from mining and production processes.
Griffith concluded that the heat-killed bacteria somehow converted live avirulent cells to virulent cells, and he called the component of the dead S-type bacteria the “transforming principle.” Fig. 1.1. Schematic diagram of Griffith's experiment which demonstrates bacterial transformation.
<u>Answer:</u>
B. Theories are broad explanations based on many observations and experiment
This statement accurately describes a scientific theory
<u>Explanation:</u>
Scientific theory can be defined as hypothesis which have been supported through research which is using the scientific method. Hypothesis is simply educated guess. It is the beginning stage of the scientific theory
There are many characteristic of scientific theory. These characteristics are testable, replicable, stable, simple and consistent. A theory explains the findings made throughout the review process. A scientific theory may not be the scientific test's final outcome; Scientific theories are interpretation of scientists. It can be changed or sometimes also rejected.
Answer:
<em>The best inferential explanation is that the heavy metal concentration was gotten from the build up of small amounts of heavy metal in the birds, gotten from consuming fishes from a heavy-metal -polluted water body.</em>
<em></em>
Explanation:
If a sample of fish-eating bird species is found to contain such a large concentration of heavy metal, then the primary source of the heavy metal concentration in their body will be from their food source. Fish-eating birds are in most cases, solely dependent on fish for their food. Most of them do not eat any other food apart from fish, so the problem can be pin-pointed to the fishes they consume. <em>The best inferential explanation is that the heavy metal concentration was gotten from the build up of small amounts of heavy metal in the birds, that is gotten from ingesting fishes that have ingested heavy metals in them. This can be as a result of the pollution of water bodies like streams, lakes and seas from heavy-metal-containing industrial wastes. </em>
Answer:
It's an alarming situation about the decline of commercial fish population and we must need to develop the policy solution to this dangerous fisheries problem.
We can develop more fish by fish hatcheries to increase the population of fish and release large number of fish into the ocean.
We should give the awareness to the general public related to decrease the recreational fishing impact.
Commercial fishing must be ban until we reaches the sustainable level of fish.
There must be place international limits to every country related to limited number of fish they can take.
