Answer:

Cambrian explosion

Explanation:

Cambrian explosion is a geological event that happened during the Cambrian age (541 million years ago). In this period, most of the animal phyla (including marine) appeared and their geological record is preserved in the form of fossils. The period lasted for 13-25 million years. Before this period, the organisms were very simple. They were mostly unicellular in nature and were living in the form of colonies.

The remaining three options are incorrect. They are tectonic events that reflect movement of continents in different geological times. None of them resulted in the diversification of (marine) animal phyla.

A man who is an achondroplastic dwarf with normal vision marries a color-blind woman of normal height. The man's father was six
Degger [83]

Answer:

1/4.

Explanation:

The autosomal dominant trait means that the trait is visible in homozygous dominant and in heterozygous condition. The X linked recessive trait will be pass down from mothers to their sons and daughters will show the trait in homozygous recessive condition only.

The man is achandroplastic dwarf ( Aa) with normal vision (XY ) is married with woman that has normal height (aa) with color blind (XhXh). They have a daughter who is dwarf ( Aa). The probability of being dwarf can be calculated by the cross Aa × aa. The offspring are Aa, Aa, aa, aa. Means 1/2 are the probability of being hetterozygous for achondroplastic . The vision probability is calculated by cross XY and XhXHh. The probability that female is heterozygous is 1/2.

So, the heterozygous probability for both trait is 1/2× 1/2 = 1/4.

GaryK [48]
<h2>The correct answer is: Mutualism.</h2>

Explanation:

  • Mutualism can be defined as a type of symbiotic relationship.
  • Symbiosis can be defined as the type of ecological interplay in between two species localized in the same habitat in which at least one of the species gets benefited in the form of food, shelter or protection due to the interaction.
  • Mutualism is a type of positive symbiosis in which both the species involved in the ecological interplay benefits due to the interaction in between them.
  • In the given question, some micro-organisms survive in the digestive tract of the cattle.
  • These micro-organisms produce the enzyme, cellulase, which helps in digesting cellulose present in the food consumed by the cattle.
  • The cattle is incapable of producing this cellulase enzyme by itself and is dependent on the micro-organisms for its synthesis.
  • Hence, the the micro-organisms help the cattle in obtaining nutrition and energy by the digestion of cellulose.
  • On the other hand, the micro-organisms get shelter, nutrition and protection in the gut of the cattle.

Regarding human traits, which individual would most likely agree with aristotle?
fiasKO [112]

Regarding human traits,  Locke would most likely agree with Aristotle.

There are more areas where Aristotle and Locke's philosophical views diverge than where they concur. For instance, Aristotle once claimed that a person's happiness was just as important to them as it was to their political community. The political understanding of Locke, however, is different because, in his view, a government only assumes responsibility for a portion of the human rights that it is meant to protect in accordance with what people deem to be right. Individuals are therefore given priority because they have rights that are inalienable and shouldn't be manipulated by people to fit their agenda. These and other traditional philosophies have been used to analyze and comprehend early philosophy.
