Which of the following statements about evolution is TRUE? Evolution describes how an individual's offspring develop from juveni

les to adults. Evolution cannot be observed directly, so it must be interpreted through indirect evidence. Evolution occurs when an individual changes within its lifetime, to better fit its environment. Selective survival and reproduction is a requirement of evolution by natural selection.

Answer:

The correct answer will be option-Selective survival and reproduction is a requirement of evolution by natural selection.

Explanation:

Evolution is a slow process of change in the heritable features of species over a successive generation of time.

The process of evolution takes place during a long period of time only when the advantageous mutations are passed on to the generations and become established.

The mechanism of this process is natural selection which increases the reproductive rate as well as the survival rate of the species.

Thus, the selected option is the correct answer.

In which biome would you most likely find plants that grow far apart from one another, with narrow leaves and shallow roots? Why
stiks02 [169]
<span> A plant with narrow leaves and shallow roots would probably be found in the desert, where there is not a lot of water. Narrow leaves help prevent water loss. Shallow roots can spread out long distances in search of water. Plants living in the desert grow far apart from one another so that they don’t have to compete for limited amounts of water.</span>

Last week you were wondering what Jessica and Tom's babies might look like with respect to their eyebrows and earlobes (both Tom
mash [69]

Answer:

25%

Explanation:

The possible genotypes and phenotypes are:

  • EE or Ee: thick eyebrows
  • ee: thin eyebrows
  • FF or Ff: free earlobes
  • ff: attached earlobes

Tom and Jessica have thick eyebrows and free earlobes. Tom's mother has attached earlobes, so Tom must have inherited an <em>f</em> allele from her, and because he has free earlobes he must be heterozygous<em> Ff. </em>We assume Jessica is homozygous for free earlobes <em>FF</em>.

Tom's mother and Jessica's father have thin eyebrows, so they are both <em>ee</em> and therefore both Tom and Jessica must be heterozygous <em>Ee</em>.

From the above information, Tom has the genotype EeFf and Jessica is EeFF. If you do a Punnett Square of this cross, you'll get that the probability of having a child with free earlobes and thin eyebrows (eeF_) is 25%.
