Suppose we found a solar system with the property described below. In light of what you have learned about the formation of our

solar system, decide whether the discovery should be considered reasonable or surprising. (a): A solar system has 15 planets that all orbit the star in approximately the same plane. The two planets closest to the star are terrestrial and the rest are gas planets?

Answer:

Surprising

Explanation:

This is surprising because the total number of planets in our solar system are nine which revolve around a central star i.e sun in different orbital paths.  

Also, out of 9 nearly four planets i.e Mercury, Earth, Venus and Mars are terrestrial i.e having some land forms. Out of remaining 5 non terrestrial planets nearly four planets are gas planets (Jupiter, Uranus, Neptune and Saturn) and these planets are distantly positioned from the central star

Hence, the given discovery is surprising

which structure in the female reproductive system is comparable to the external reproductive organs in males
Oksi-84 [34.3K]
They are the same in that most of the reproductive organs of both sexes develop from similar embryonic tissue, meaning they are homologous. Both systems have gonads (male have testes and female have ovaries) that produce gametes (testes produce sperm and ovaries produce egg or ovum) and sex organs.

Answer:

Natural selection can cause microevolution (change in allele frequencies), with fitness-increasing alleles becoming more common in the population.

Fitness is a measure of reproductive success (how many offspring an organism leaves in the next generation, relative to others in the group).

Natural selection can act on traits determined by alternative alleles of a single gene, or on polygenic traits (traits determined by many genes).

Natural selection on traits determined by multiple genes may take the form of stabilizing selection, directional selection, or disruptive selection.

Introduction

We've already met a few different mechanisms of evolution. Genetic drift, migration, mutation...the list goes on. All of these mechanisms can make a population evolve, or change in its genetic makeup over generations.

But there's one mechanism of evolution that's a bit more famous than the others, and that's natural selection. What makes natural selection so special? Out of all the mechanisms of evolution, it's the only one that can consistently make populations adapted, or better-suited for their environment, over time.

You may have already seen natural selection as part of Darwin’s theory of evolution. In this article, we will dive deeper – in fact, deeper than Darwin himself could go. We will examine natural selection at the level of population genetics, in terms of allele, genotype, and phenotype frequencies.

Quick review of natural selection

Here is a quick reminder of how a population evolves by natural selection:

Organisms with heritable (genetically determined) features that help them survive and reproduce in a particular environment tend to leave more offspring than their peers.

If this continues over generations, the heritable features that aid survival and reproduction will become more and more common in the population.

The population will not only evolve (change in its genetic makeup and inherited traits), but will evolve in such a way that it becomes adapted, or better-suited, to its environment.
