What groups of organisms are most in danger of extinction?

A. Those with small population
B. Those that migrate or need special habitats
C. Those with large populations that breed quickly
D. Both a and b

Answers

Answer 1

Explanation:

D.Both a and B

As organisms with small population and those who migrate and need special habitat are most in danger of extinction.

Answer 2

The group of organisms that are in danger of extinction is those that have small populations and those that migrate or need special habits. So the correct option is D.

What is the extinction of species?

In biology, extinction refers to the extinction or death of a species. Extinction happens when a species' numbers are reduced due to evolutionary changes in its members, such as genetic inbreeding, poor reproduction, and population decline, or due to environmental factors like habitat fragmentation, climate change, natural disasters, and overexploitation of the species for human use.

The majority of species that have ever existed on Earth have gone extinct, but the fossil record indicates five very significant extinctions, known as mass extinction events, each of which resulted in the extinction of enormous numbers of species. The bulk of extinctions, which happen continuously and are described as background extinctions, are separated from these glaring decreases in the variety by the term "mass extinction."

Therefore, the correct option is D.

According to natural selection theory, Different species occupying the same habitat will adapt to that habitat by undergoing the same genetic changes Adaptations beneficial at one time should generally be beneficial during all other times Well-adapted individuals have more offspring, and thus contribute more to the next generation's gene pool, than do poorly adapted individuals. Adaptations beneficial in one habitat should generally be beneficial in all other habitats

Answers

Answer:

The most correct statement is - Well-adapted individuals leave more offspring, and thus contribute more to the gene pool, than poorly adapted individuals.

Explanation:

Adaption in natural selection is a species, time-specific, and habitat-specific process. So, it means if a species is adapted to genetic changes in a particular habitat, it is not necessary that all other species also adapt to similar genetic changes.

Similarly, if a species has beneficial adaption for a particular habitat, it is not necessary it will be beneficial for the other habitat as well.

Thus, natural selection leads to the well-adapted individual that leave more offspring and contribute more to the gene pool.

Which do scientists link to increased hurricane strength?
O A. Higher ocean temperatures in the arctic
B. Higher land temperatures in the arctic
C. Higher ocean temperatures in the tropics
O D. Higher land temperatures in the tropics

Answers

Answer:

Higher ocean temperatures in the tropics

Explanation:

apex :)

Higher ocean temperatures in the tropics are linked to increased hurricane strength. Therefore, option (C) is correct.

What is hurricane strength?

Hurricane strength is a measure of the intensity of a tropical cyclone, which is a rotating storm system that forms over warm ocean waters in the tropics. The strength of a hurricane is measured using the Saffir-Simpson Hurricane Wind Scale, which ranks hurricanes from Category 1 (weakest) to Category 5 (strongest) based on their sustained wind speeds.

Hurricanes can cause significant damage due to their strong winds, heavy rainfall, storm surges, and flooding. The strength of a hurricane is influenced by a variety of factors, including warm ocean temperatures, low wind shear, and high humidity. As global temperatures continue to rise due to climate change, it is expected that hurricanes will become more frequent and more intense, which could have significant impacts on coastal communities and infrastructure.

B. Nitrogen gas in general is one of the main air pollutions. otherwise know as Nitrogen dioxide.

C. Nitrates are found in ground waters and transfers into the soils surrounding said waters. Nitrates commonly are a cause of death in infants when drinking tab water or eating crops grown from nitrate infected soils. Adults aren't nearly as infected by this.

Which surface erosion event does the most short- term damage?


Loss of topsoil from farmland.


Movement of rocks by glaciers.


Occurrence of mud slides after heavy rains.


Pollution of water sources caused by runoff.

Answers

Answer:

Occurrence of mud slides after heavy rains.

Explanation:

Soil erosion is defined as the removal of top soil from the land and it affects the fertility of the soil. It is also known as soil degradation.

Soil erosion has both short-term and long-term damage. Short-term damage of erosion includes the occurrence of mudslides after heavy rains which is called landslide. It is a short-term damage because landslides took long-duration to happen and when happened it can be shortly recovered using machines.

Hence, the correct answer is "the Occurrence of mudslides after heavy rains."

What challenges do Arctic areas face as a result of global warming? 2) What measures could help deal with the problem? 3) What do you predict will happen to Arctic ecosystems if no measures are taken to reverse the problem of global warming? Explain your reasoning. 4) Which measures do you think are most important to pursue?

Answers

Answer:

Global warming is defined as the environmental issue that leads to long term heating of the earth due to human activities such as burning of fossil fuels.

1. Arctic areas are facing huge challenges due to global warming that includes rising sea levels, rapid melting of ice,  loss of fish stocks, birds and marine mammals, and changes in climate patterns.

2. Measures that help to deal with the problem are reduction in the use of hydrofluorocarbons, cutting emissions of black carbon, methane, reduce overfishing, and reduction of industrial waste.

3. If there will be no measure taken to reverse the problem of global warming in the Arctic ecosystem, it will cause flood and tsunami in the nearby continents due to the rapid melting of ice, changes in climate patterns, and lead to the extinction of many marine animals.

4.  Reduction of industrial waste is the most important measure to pursue because industrial waste contributes most of the greenhouse gases and causes air pollution, land pollution, water pollution, and nuclear pollution. So reduction is industrial waste will reduce the emission of harmful gases in the environment that can reduce the impact of global warming.
