What are biodiversity hot spots?
O A. Areas where large numbers of earthquakes and volcanic eruptions
occur
B. The warmest and driest ecosystems on Earth
C. Areas where the average annual temperature exceeds 40°C
O D. The richest and most threatened reservoirs of life on Earth
Answer: D
Explanation: Yet biodiversity hotspots are, by definition, in a conservation crisis. To be classified as a biodiversity hotspot, a region must have lost at least 70 percent of its original natural vegetation, usually due to human activity. There are over 30 recognized biodiversity hotspots in the world

Which of the following actions would decrease global warming?
Select one:
Decreasing the amount of methane in the air.
Increasing the amount of oxygen in the air.
Increasing the amount of water vapor in the air.
Decreasing the amount of nitrogen in the air.
Answer:
Decreasing the amount of methane in the air
Explanation:
Methane is a powerful greenhouse gas, which absorbs the sun's heat and doesn't allow it to escape therefore contributing to global warming
Decreasing the amount of methane in the air would decrease global warming. Therefore, option (A) is correct.
What is global warming?Global warming is the gradual increase in the Earth's average surface temperature, primarily due to the buildup of greenhouse gases in the atmosphere, such as carbon dioxide and methane. These gases trap heat and prevent it from escaping into space, leading to a warming effect on the planet.
The consequences of global warming are far-reaching and potentially catastrophic, including rising sea levels, more frequent and severe weather events, loss of biodiversity, and impacts on human health and well-being.
To address global warming, it is essential to reduce greenhouse gas emissions by transitioning to cleaner and more sustainable sources of energy, improving energy efficiency, and adopting more sustainable land use practices. Addressing global warming requires a collective effort from individuals, communities, businesses, and governments around the world.

How have volcanic emission contributed to the formation of atmosphere?
Answer:
Volcanic emission
Explanation:
Volcanoes can impact climate change. During major explosive eruptions huge amounts of volcanic gas, aerosol droplets, and ash are injected into the stratosphere. ... But volcanic gases like sulfur dioxide can cause global cooling, while volcanic carbon dioxide, a greenhouse gas, has the potential to promote global warming.

what are the limitations of cell theory
Answer:
The shortcomings or drawbacks of cell theory are: Viruses are considered as acellular entities or organisms that do not have cell machinery, yet they are taken into account as organisms in this cell theory. Matthias Schleiden and Theodor Schwann did not know the mechanism of the cell.
Explanation:
how can you determine whether an organism is a plant or organism?
Answer:
an organism is multicellular, heterotrophic (cannot make its own energy), and has no cell wall, it is an animal. This is the definition of the kingdom Animalia.
There are unicellular animal-like members of the kingdom Protista commonly called protozoa.
Fungi are heterotrophic and multicellular, but they have a cell wall made of chitin.
Explanation:
Action Potential: Relative refractory period
In a neuron, there is a period of time called the absolute refractory period where it is impossible for an action potential to
begin. This corresponds to the change in membrane potential from +30 to -70 mV, or the repolarization phase. Towards the
end of the repolarizing phase, there is a relative refractory period where it is difficult, but not impossible, for another action
potential to begin. Using the time slider function, which of the following segments in the neuron would correspond to a
relative refractory period?
A second action potential can be triggered during the relative refractory phase, but it will need a stronger stimulus to do so than the first time. Refractory times are brought on by the inactivation gate of the Na+ channel.
What Action Potential related to Relative refractory period?The axon has a tougher time producing successive action potentials during this time period, which is referred to as the refractory period, as a result of these transient alterations.
As a result, the refractory period restricts the quantity of action potentials that a certain nerve cell can generate in a given amount of action potentials time.
If enough powerful stimuli are applied to the neuron after the absolute refractory time, Na+ channels start to recover from inactivation and the neuron may respond once again by generating action potentials.
Therefore, A stimulus that is stronger than usual is required to generate neuronal activation during the relative refractory period.

Glycolysis yields Choose... molecules of ATP, while the electron transport chain yields Choose.. molecules of ATP due to the presence of oxygen.
Answer:
Glycolysis yields 2 molecules of ATP, while the electron transport chain yields 32 molecules of ATP due to the presence of oxygen.
Explanation:
Glycolysis yields 2 molecules of ATP, while the electron transport chain yields 32 molecules of ATP due to the presence of oxygen.
What is electron transport chain?An electron transport chain is a collection of protein complexes and other molecules that associate protons across a membrane with the transfer of electrons from electron donors to electron acceptors via redox processes. Both photosynthesis and cellular respiration take place in mitochondria.
An organic metabolite (an intermediary in metabolic reactions) reacts with the coenzyme NAD+ to begin the electron transport cycle (nicotinamide adenine dinucleotide). In this oxidation reaction, the organic metabolite loses two hydrogen atoms (or two hydrogen ions and two electrons).
