Answer:
The answer is "Option C".
Explanation:
In the given question, the pH scale is used to evaluate acid or basic (alkalinity) formulas. It is nearly positive throughout the blood. Human blood has to maintain its pH at about 7.4, to prevent dramatically increased or lower changes, even though the bloodstream enters or exits acidic or essential substances.
- The buffers are essential for stabilization management. Calcium carbonate produced as carbon dioxide joins the blood system and combines with the liquid is a buffer which adds to the pH level in the human blood.
- It is returned to the water and distributed as a waste product until it enters the lungs, that's why choice C is correct.
Answer:
a hypothesis is an educated guess or an assumption made before any of the research has been done.
a theory is a substained explanation for an occurrence.
a scientific law describes what has happened.
Explanation:
Answer:
The population suffered a genetic bottleneck, which decreased genetic variation and thereby randomly increasing the frequency of harmful alleles
Explanation:
A population bottleneck, also known as genetic bottleneck, can be defined as a drastic reduction in the size of a population, which may be caused by anthropic activity and/or environmental phenomena (e.g., earthquakes, famines, fires, droughts, etc). A genetic bottleneck leads to a reduction in genetic variability within a population. Moreover, the genetic drifit caused by a genetic bottleneck can also increase the frequency of harmful alleles/mutations (it is due to the random sampling of individuals), thereby increasing the frequency of deleterious alleles/mutations in the population.
Because the organism that causes botulism can not survive when exposed to air- it is anaerobic
1. Trenches
2. Mountain/Volcano formations as well as earthquakes
3. Earthquakes and tsunamis
4. It has made formations like the Marianas Trench, The Ring of Fire, and the Haiti earthquake
