Questions: Question 3 Sympatric speciation occurs when two populations experience different mutations. living in the same location experience different selection pressures. form fertile hybrids are physically separated from each other. Question 4 Adaptive radiation occurs when a mutation caused by solar radiation produces adaptations. a population expands across a uniform habitat multiple new species are produced because subpopulations adapt to new environments a species loses adaptations through mutation

Question 3:

The answer is the second one: living in the same location experience different selection pressures.

Explanation:

• The first option, "experience different mutations," is not specific to sympatric speciation, as mutations can occur in any speciation process.
• The second option, "living in the same location experience different selection pressures," correctly describes sympatric speciation, where populations in the same geographic area diverge due to different ecological niches or selection pressures.
• The third option, "form fertile hybrids," is not related to sympatric speciation but rather to hybridization.
• The fourth option, "are physically separated from each other," describes allopatric speciation, not sympatric speciation.

Question 4:

The answer is the third one: multiple new species are produced because subpopulations adapt to new environments.

Explanation:

• The first option, "a mutation caused by solar radiation produces adaptations," is incorrect as adaptive radiation is not about mutations caused by solar radiation.
• The second option, "a population expands across a uniform habitat," does not describe adaptive radiation, which involves diversification into different niches.
• The third option, "multiple new species are produced because subpopulations adapt to new environments," accurately describes adaptive radiation, where a single ancestral species rapidly diversifies into a variety of new forms to exploit different ecological niches.
• The fourth option, "a species loses adaptations through mutation," is incorrect as it does not describe the process of adaptive radiation.
