<u>Answer</u>: The answers are matched as follows:
African forests have been hunted to near extinction levels to obtain ivory-------------->human exploitation
The eruption of mount Saint Helens destroyed some populations of conifers------> natural disasters
An infection with a fungus reduced the population of North American Elm trees ----> disease
Increasing global temperatures have altered migration patterns of humpback whales ------>climate change
<u>Explanation</u>:
- <em>Human</em> <em>exploitation</em> is the unethical or selfish use of resources to satisfy their own personal needs or for any profitable activity which harms the resources in such a way that they get limited. Humans have been hunting elephants to obtain ivory for many purposes such as making jewellery etc. and earning profits from it. Due to such extensive hunting they have driven the elephants to a level of extinction and thus, this is a form of human exploitation.
- Mount Saint Helens is a volcano and its eruption which harms the population of the trees in the area is a form of natural disaster since volcanic eruption is a <em>natural</em> <em>phenomena</em>.
- Fungal infection is a <em>disease</em> which is cause by the microorganisms which harms the population of the Elm trees.
- Increase of global temperature is a type of climate <em>change</em> and thus, this effect of alteration of migration pattern is caused by climate change.
Answer: Cells need to be able to survive
Explanation: they adapt
Answer:
diastolic pressure
Explanation:
Your blood pressure is highest when your heart beats, pumping the blood. This is called systolic pressure. When your heart is at rest, between beats, your blood pressure falls. This is called diastolic pressure.
A mutation is a rare, accidental or induced modification of genetic information (DNA or RNA sequence) in the genome.
The consequences of a mutation vary according to the part of the genome affected. A mutation is said to be hereditary if the mutated genetic sequence is passed on to the next generation.
In multicellular animals, germline mutations can be transmitted to offspring, whereas somatic mutations do.
Somatic mutations do not affect cells intended for reproduction, so they are never hereditary:
* Post-zygotic mutations are the mutations that appear in the egg after fertilization. They are rarer and are expressed as mosaic in the individual concerned (the mutation will be present only in the daughter cells originating from the mutated embryonic cell).
* Mutations can appear throughout life on the DNA of any cell; they are then transmitted to the line of the daughter cells. These can, in some cases, become tumor cells and then form cancer.
Answer:
The suspect might be guilty, but more information is needed from other parts of the investigation.
Explanation:
Due process states innocent until proven guilty. Having an 80 percent chance of deception is not solid proof of anything. It does, however, bring more speculation to the table that this person is indeed guilty, but because there is no actual proof, the investigators must find more information on the matter.
