Using your compass, draw a circle with a radius equal to the number you came up with in Step #2 (the radius is the distance from the center of a circle to its edge). The center of the circle will be the location of your seismograph. The epicenter of the earthquake is somewhere on the edge of that circle.

Warm and acidic water leads to bleaching of coral reef and the new algae can survive due to mutation in its gene.

The biggest threat to coral reefs in the Persian gulf is the warming of waters due to climatic change as well as acidification of water. Algae present on coral reefs can't tolerate acidic water as well as warm water which leads to the death of algae and the coral looks white or colorless.

A new organism was the most commonly found algae throughout the gulf's coral reefs due to change in the genetic makeup due to harsh climatic conditions so we can conclude that warm and acidic water leads to bleaching of coral reef and the new algae can survive due to mutation in its gene.

Via cytotoxic cells. When a virus infects a person (host), it invades the cells of its host in order to survive and replicate. Once inside, the cells of the immune system cannot 'see' the virus and therefore do not know that the host cell is infected.

Some aquatic salamanders (and all tadpoles) have gills and can breathe underwater thanks to them. The Mexican axolotl, for example, never loses its gills.

Explanation:

Changes in an ecosystem may benefit one organism by removing predators while affecting the predator species negatively.

Changes that occur in an ecosystem may occur as a result of natural or man-made causes.

Changes in an ecosystem may have positive or negative effects on the interdependence of organisms in a specific habitat.

For example in an aquatic habitat where certain species of fishes like sharks depends on smaller fishes like salmon to survive, if humans were to reduce the salmon population by overfishing, the sharks will be negatively affected as they may have to migrate to new hunting grounds.

However, some other fishes that are prey to shark may be able to grow more with the reduction on shark population in that area.

Therefore, changes in an ecosystem may benefit one organism by removing predators while affecting the predator species negatively.

Answer:

Its "C"  Inversion

Explanation:

I took the test and got it correct

Type of mutation reverses the direction of parts of a chromosome is inversion. The correct answer is option C.

The chromosomes are thread like structures present in the nucleus and the  these chromosomes carry the genetic information in them from one generation to another.

Inversion inverts the structure of chromsome and it basically turns the chromsomes inverted.

Inversion is the process where one arm of the chromosome gets detached from the basic structure and it gets attached in the inverted direction.

This  creates multiple copies of DNA turning it into genetic material and one of the X linked recessive disorders is haemophilia in which same type of mutation caused by the chromosome at the 8th position takes place.

Therefore, Mutation that reverses the directions of the part of the chromosome.
