The mitochondria converts chemical energy stored in food into usable energy.
Answer:
This question is incomplete as the term to match with the level of organisation is not included, the terms are;
circulatory system
cardiac muscle
heart
human body
The ANSWER is:
Organ = heart
Organ system = circulatory system
Tissue: cardiac muscle
Explanation:
The level of organization of multicellular organisms is made up of cell, tissue, organ, organ system and eventually organism.
- The tissue is composed of several cell, which are basic units of any living organism. Cells that perform similar function come together to form the tissue. Example is the CARDIAC MUSCLE in this question, which is a muscular tissue made up of cells called myocardiocytes.
- Organs are structures formed as a result of collection of tissues with similar function. For example, the HEART is a circulatory organ made up of cardiac tissues, connective tissues etc.
- Organ systems is made up of organs that perform the same function in a living organism. In the case of the CIRCULATORY SYSTEM, it is made up of organs such as heart, blood vessels, lungs etc.
Answer:
Yes a false positive result will be read
Explanation:
Instructions on most pregnancy tests will tell you to read the results in a certain amount of time, usually from a couple of minutes. So you may take a pregnancy test and read it within the above time period as negative.
If you happen to keep the test around to look at later, you may notice that after that allotted time, the test now appears to have a positive result. This is called an evaporation line. It is not indicative of a positive pregnancy test.
What is Evaporation Lines?
Evaporation lines happen when the urine that was on the test area starts to dry out and evaporate. The chemical composition of that particular urine sample has now changed since that urine sample evaporated, sometimes causing the test to show a positive line
Answer and Explanation:
To determine the overall health of the alligator pond, Mr. Ortiz should carry out the following tests:
pH is extremely important in this type of research as a reduction of pH could lead to a higher availability of toxic metals that may be absorbed by aquatic organisms such as alligators and fish species.
<em>pH is acceptable in a range of 6.5 to 8.2.</em>
- <u>Nitrates and Ammonia (NH3) levels</u>
Oversaturation of nitrates and ammonia could lead to the death of organisms that are crucial for the maintainance of a healthy pond and for the balance of the food chain.
Moreover, it could lead to algal blooms that result in a lower concentration of oxygen available for other organisms.
<em>Over 0.2 per L could be lethal</em> to some fish species that are also important for the health of the alligator pond.
<em>Less than 0.1 </em>indicates a healthy alligator pond.
- <u>Bacterial coliform test</u>
This test determines the amount of bacteria that comes from waste (animal or human), which could lead to mild to serious bacterial infections and diseases.
If it is a healthy pond, the results should indicate <em>less than 10 fecal coliform bacteria/100 mL.</em>
