Answer:
Safety glasses and safety goggles are used in the laboratory to protect the eyes. Safety goggles provide the best protection from chemicals splashing in the eyes because they protect the sides of the face. Safety glasses do not protect the sides of the face, so chemicals could still get into the eyes.
The correct answer is B. They evolved from a shared ancestor
Explanation:
In biology, the word clay refers to a set of organisms that have a common ancestor and because of this, they are placed in the same ramification or branch in a phylogenic tree, which allows biologists to classify organisms in groups. For example, all birds are believed to have a common ancestor and therefore they formed a clade. However, belonging to the same clade does not imply the same exact classification, identical phylogenies or characteristics because these depend on each species and varies due to the evolution process. Therefore the statement that is true about organisms that are part of the same clad ie that they evolved from a shared ancestor.
Answer:
11.63 percentage of the earthquakes are minor earthquakes
Explanation:
Given:
The number of earthquakes that that occur annually = 421,140
The number of minor earthquakes that that occur annually = 49,000
To Find:
Percentage of minor earthquakes =?
Solution:
let the percentage of minor earthquake be x
then
x =
x =
x =
x= 11.63
Answer:
Reproductive success of an individual is measured in term of its genetic contribution to the future generation as compared to that of other individuals of the same population.
Explanation:
Natural selection is the ability of some organisms to survive better and reproduce more due to the presence of some beneficial genetic traits. These individuals are able to leave more progeny as compared to the other individuals of the same population that lack those genetic traits. Therefore, reproductive success represents the ability of an organism to leave more progeny to contribute more to the gene pool of future generations.
