Explain how competition could limit the size of a bird population

Answers

Answer 1

Answer: when there is competition for food the strong will survive while the weak don't. Therefore there would be a larger population of the bigger, stronger birds and less of the smaller weak birds. hope that helps you

Which is an example of genetic drift?A. The allele frequency of a population changes due to a bottleneck
effect.
B. Disruptive selection divides a population into two new species.
C. Selective breeding creates a new species of dog.
D. A mutation spreads rapidly through a small population.

Answers

The example of genetic drift is A. The allele frequency of a population changes due to a bottleneck effect.

What is a genetic drift ?

Genetic drift refers to random fluctuations in the frequency of alleles (variants of a gene) in a population over time. This can occur due to various factors, such as a reduction in population size or migration of individuals between populations.

The bottleneck effect is a type of genetic drift that occurs when a population experiences a sharp reduction in size, which can reduce the genetic diversity of the population. This can result in certain alleles becoming more common or being lost altogether, even if they were not necessarily more advantageous or disadvantageous for survival.

Disruptive selection (option B) and selective breeding (option C) are mechanisms of natural and artificial selection, respectively, and do not necessarily involve random fluctuations in allele frequencies.

Hence, A mutation spreading rapidly through a small population (option D) could be an example of genetic drift if it results in a change in allele frequency, but the fact that it spreads rapidly suggests that it may be under the influence of natural selection instead.

A. The allele frequency of a population changes due to a bottleneck.

This is because genetic drift happens because of chances events such as founder effect of bottleneck effect

The invention of the microscope in the 1600's was one of the most important inventions in the history of science. The microscope opened up a previously unseen world. Which theory developed most quickly and even changed as a result of the microscope?\

Answers

Answer:

The cell theory developed most quickly due to the invention of the microscope. Robert Hooke was the first scientist who saw cells in cork. After this discovery, a wide numbered of researches were made and cell theory was developed. The basic cell theory explained that how every living thing was made up of cells. After this, a lot of additions have been made in the cell theory and today the cell theory is known to have five basic postulates.

What behavioral adaptations help snakes survive in hot dry places

Answers

Snakes have several behavioural adaptations that help them to survive in hot and dry places. One behaviour that a snake does is to make their head appear larger by spreading it apart. They will also roll over on their back to appear to have a seizure/convulsion to scare away predators. To survive in hot/dry places such as the desert, a snake will use thermoregulation. They do this by laying in the sun at optimal times such as late afternoon, midday, and sometimes early morning. This helps them to avoid the extreme temps. Many snakes can also make themselves blend into the environment around them and look like the surrounding landscape. Snakes have also evolved so that they won't need much hydration in the desert. They will get the water they need from the prey they eat.
