Answer:
Option C
Explanation:
If we consider Darwin's theory we would realize that the species which are not able to survive are unfit or weak. Thus, predators usually attack species that can be easily targeted. Hence, it this way predation leads to selective pressure on any species and hence leads to creation of a fit gene pool. The weak organisms are removed and more fit organism could mate among themselves to produce healthy offspring.
Hence, option C is correct
Answer:
The answer is A, B, C and E.
Explanation:
Genetic counselors are responsible for recommending genetic testing according to the need of the patient and then guiding them through the process and helping with their decision after interpreting the genetic test results.
Out of the given options in the question, D does not apply to the given statement that if a genetic counselor recommends a genetic test or not because wanting to increase an unborn child's intelligence is unethical and is in the field of genetic engineering which is not approved.
The examples given in the options A, B, C and E are all examples of people that are seeking treatment for themselves either for curing a disease or preventing it and in those cases, the genetic counselor can recommend a genetic test.
I hope this answer helps.
Answer:
Objective Lens Magnification = ×100
Explanation:
In a microscope, the ocular (eyepiece) lenses are usually to a magnification of ×10, meaning that it magnifies the image 10 times. While the standard objective lenses have magnifications of ×4, ×10, ×40, and ×100.
In order to work out the total magnification, the individual magnifications of the ocular and objective lenses have to be known, after which a simple multiplication of both magnifications will give the total magnification used.
Total Magnification = (eyepiece lens magnification) × (objective lens magnification)
1000 = 10 × obejcetive lens magnification
Dividing both sides by 10
Objective lens magnification = 1000 ÷ 10 = 10
∴ Objective lens magnification = ×100
