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:
Mendel was an Austrian monk whose researches laid the foundation of genetics. The experiments conducted by Mendel led him to the foundation of two laws which are named as the law of segregation and law of independent assortment.
According to the law of segregation, the two alleles of a gene segregate during the time of gamete formation and there are 50-50% chances of each of the alleles to be received by the gametes. Hence, there are 50% chances for Y gametes to be produced and 50% chances for y gametes to be produced.
An isotonic solution is when the solute concentration is balanced with the concentration inside the cell , the water movement still moves between the solution, but the rates are the same in both directions, the water is balanced inside and outside the cell .
A hypotonic solution is when the solute concentration is lower than the concentration inside the cell. water moves into the cell and can cause the cell to swell; cells that don’t have a cell wall, such as animal cells, could explode in this type of solution.
A hypertonic solution is when the solute concentration is higher than the concentration inside the cell. In a hypertonic solution, the water moves out of the cell and causes the cell to shrivel.
Answer:
- <u>a review of published literature (secondary data collection)</u>
- <u>carry out interviews</u>
- <u>perform a survey</u>
Explanation:
1. <u>Review published literature:</u> This method involves reading through already published works containing meaning data about the particular field of study. For example, you read through textbooks, past newspapers, magazines, academic papers, etc.
2. <u>Carry out interviews:</u> This simply requires face to face or a virtual one on one interactive session with your respondents in other to record the data they provide.
3. <u>Perform a survey:</u> A survey here implies that issuing out a paper-based questionnaire or an online questionnaire (form) to be filled by the subjects of the research.
I believe the correct answer from the choices listed above is the third option. This phenomenon validate the Law of Conservation of Energy by the statement that says the <span>light energy travels through the water until it is reflected or absorbed. Hope this answers the question.</span>
