Mass extinction refers to the procedure in which a huge number of species gets extinct suddenly.  

The following are the correct matches of the events taken place in the mentioned time period:  

1. Cretaceous-Tertiary: The mass extinction of dinosaurs took place.  

2. End-Triassic: Possibly resulting due to massive rifting of the surface of the Earth.  

3. Permian-Triassic: It is considered the worst mass extinction in the history of the Earth.  

4. Late Devonian: It is possibly a result of the growth of forest on the land surface of the Earth.  

5. Ordovician-Silurian: The earliest mass extinction took place at this time.

The driving force presented by Wegener for his hypothesis was that continents ploughed through ocean crust.
babymother [125]

Answer:

"Alfred Wegener suggested that continental drift occurred as continents cut through the ocean floor, in the same way as this icebreaker plows through sea ice. ... The supercontinent later broke apart and the continents having been moving into their current positions ever since. He called his hypothesis continental drift."

Accumulation of DDT in the testes may cause reduced fertility in males because the uncoupling of oxidative metabolism from ATP p
kow [346]

Answer: Is most likely to result from reduced ATP levels.

Explanation:

Dichlorodiphenyltrichloroethane (DDT) is a colorless, odorless, tasteless, crystalline compound. It is an organochloride. It is used as an insecticide. It is associated with damage of biodiversity and several human and animal health complications.

In human males DDT is associated with decrease in fertility. As it results in low sperm count, negatively affects the sperm motility and synthesis.

The uncoupling process will reduce ATP synthesis in the mitochondrial cells of the sperms. This may lead to low sperm motility in the vaginal canal of the female after the insemination process. Thus this will reduce the male fertility.

In the natural selection simulation we set the fitness of rr individuals to 0. Why does the r allele persist in the population?
Sveta_85 [38]

Answer:

In the clarification section elsewhere here, the definition of the concern is mentioned.

Explanation:

  • The notion of fitness seems to be the basic phenomenon of Fisher. Fitness is a dynamic term since it is the calculation by a person in his lifetime of the cumulative production of viable progeny. The fitness of an organism is zero even though no offspring is created. With a growing life span as well as the amount of order to promote innovation, flexibility increases. Members of an organization that are very well-adapted to that certain range of environmental factors have had a benefit in the mechanism of selective breeding over others who might not be as possibly the best adapted. The benefit falls throughout the form of genetic diversity and longevity.
  • Those people who are much more able to easily find and use food supplies, for example, would live considerably longer and have more offspring than someone who is less reliable at seeking food. Inherited features that increase human fitness are then passed on to their descendants, thereby providing this very same value to the descendants.
  • The disappearance of fewer adapted varieties seems to be the most drastic alternative. Unless the best-adapted variant doesn't adjust even though it is as when the optimum balanced local, so for the ideal characteristic, less drastic will delete both-new variant.
  • Since less drastic selection has become too inadequate to aggressive edge mutations, the aggregation of missense mutations will happen and even the outcome would be a progressive deterioration of genomic integrity. If it maintains you prolonged enough, this should contribute to disappearance for certain species; nevertheless, the subsequent widespread presence of the deleterious mutations just seems like such a genome would then inevitably also contribute to backward mutation incidence. Extinction could result if the intense choice has become too high for the entire world, because if the world is saved in time.
