Following general conditions are necessary for natural selection to occur in population:

  • More organisms are born than can survive.
  • Organisms vary in their characteristics, even within a species.
  • Differences in reproduction and survival are due to variation among organisms.

According to Charles Darwin's theory of evolution by natural selection, organisms that possess heritable traits that enable them to better adapt to their environment compared with other members of their species will be more likely to survive, reproduce, and pass more of their genes on to the next generation.

Galapagos Finches: The Galapagos finches studied by Darwin on his famous voyage are probably the most common example of natural selection.

A portion of a field has drained more rapidly than the rest, leading to drought conditions in that area several days before the
Andrew [12]

Answer:

Due to sloppy nature of the field.

Explanation:

This problem of rapidly drainage can be solved if the field should leveled because the portion is rapidly drained due to sloppy nature of the field. Sloppy nature of land moves water at the faster rate from higher elevation to lower elevation. We can see in tillage practices, the farmers used levelers in order to level the field in order to provide even resources such as fertilizers and water. So we can say that this problem can be solved if the field will be leveled.

QUESTION 1 Global temperature trends can be inferred from changes in ________ and ________. fossils; chemical isotopes found in
kirza4 [7]

1. fossils and chemical isotopes found in sediments and glacial ice

By studying the type of climate fossilized species preferred global temperature trends can be inferred. The changes in the concentration and type of isotopes are also an accurate measurement tool of these changes.

2. decrease in mortality because winter is warmer

The phenomenon known as global warming will bring more extreme weather. Thus, it is possible for some winters to be very cold and summers be very warm.

Even with warmer winters, the mortality will not decrease. Without a snow cover, pests such as mosquitoes and pathogens will thrive and live for longer periods of time. Thus, the spread of diseases will increase which will lead to potential increases in mortality.

3. all activities by humans affecting the Earth and its biosphere

Anthropogenic activities are all activities by humans affecting the Earth and its biosphere.

4. decline in sea ice

The main cause behind declining numbers of polar bears is the diminishing size of the sea ice. The bears use the ice as hunting ground where they stalk seals.
