1. Areas in ecosystems that produce more carbon than they require are known as
a. carbon sink
b. carbon neutral
c. carbon source
d. carbon bank
Answer:
c. carbon source
Explanation:
A "carbon source" refers to processes that hastens carbon release into the atmosphere more than what they absorb. Example of this is the burning of nonrenewable resources like fossil fuels.
The combustion of fossil fuels increases the release of carbon dioxide. Carbon is then being trapped into the atmosphere. This contributes to "global warming."
This is opposite to "carbon sink," which absorbs most of the carbon than they emit.

1. Over time, the climate of an island became drier, which resulted in changes to the populations of various island finch species. Finch populations with a certain beak shape thrived, while those not having that beak shape decreased, Which of the following describes a necessary condition for thesechanges in the finch populations to occur?
Answer:
A necessary condition for the changes in the finch populations to occur in response to the drier climate would be:
- Variation in beak shape within the initial population: There must have been existing genetic variation in the population of finches regarding beak shape. Some finches would have had the beak shape that provided an advantage in obtaining food resources in the drier climate, while others would have had different beak shapes.
Without this initial variation in beak shape, there would be no opportunity for natural selection to act and favor individuals with the advantageous beak shape. Therefore, the presence of genetic variation within the population is necessary for the changes in the finch populations to occur.
Based on the theory of natural selection, the necessary condition for the changes in the finch populations to occur is limited food resources. Option B
What does natural selection say?Natural selection is the process by which populations of living organisms adapt and change over time.
Natural selection occurs when there is variation within a population of a species, and some individuals are better able to survive and reproduce than others.
These individuals are more likely to pass on their genes to the next generation, and the population will gradually change over time.

What would be the most likely result if humans stopped burning fossil fuels?
A. Greenhouse gases levels would decrease
B. The polar ice caps would melt more quickly
C. There would be less oxygen in the atmosphere
D. Global warming would increase
Answer:
A. Greenhouse gases levels would decrease.
Explanation:
Hope this helps!
Answer:
A. Greenhouse gases levels would decrease
Explanation:
Burning fossil fuels like coal, oil and natural gas for energy releases greenhouse gases like carbon dioxide and methane into the atmosphere. These greenhouse gases contribute to global warming by trapping heat in the atmosphere. If humans stopped burning fossil fuels, it would dramatically reduce the amount of new greenhouse gases being emitted. This would allow atmospheric greenhouse gas levels to gradually decrease over time as natural processes absorbed some of the excess gases.
The other answers are not likely results:
B. The polar ice caps would melt more quickly - Stopping fossil fuel combustion would actually help slow the melting of polar ice caps by reducing global warming.
C. There would be less oxygen in the atmosphere - Fossil fuel combustion does not significantly impact atmospheric oxygen levels.
D. Global warming would increase - Ending fossil fuel use would lead to less global warming in the long run by reducing greenhouse gas emissions.
So in summary, the most immediate and likely result of humans stopping fossil fuel combustion would be decreasing levels of greenhouse gases in the atmosphere, as option A states. This would then help slow climate change impacts like polar ice melting.

Explain why habitats with high biodiversity tends to contain narrow ecological niches and white habitats?
Answer:
because they reduce interspecific competition
Explanation:
Narrower niches are known to be more specific and limited compared to broader niches, which are generally less specific and less limited. The species that live in broad niches are named generalists because they are able to withstand different conditions. A narrow niche is often correlated with reduced overlap and thus tends to reduce interspecific competition. For example, coral reefs consist of a wide variety of species (including anemones, sea sponges, sea fans, brain corals, etc) which have narrow niches, thus showing high biodiversity.

NREM (non rapid eye movement ) is the stage of sleep comes before REM sleep.
What is sleep stage?Sleep stages are nothing but electrical wave activities in the brain. This wave movement is measured by an electroencephalogram (EEG). There are 2 main stages in our sleep such as REM and NREM.
The NREM is the first stage of the sleep cycle. It has 3 substages - N1, N2, N3 stages. In the N1 stage individuals feel sleepy, hallucinates. It is the light sleep stage and people can awake from this stage of sleep easily.
N2 stage is the next sleeping stage. In this stage, the electrical waves are more and called theta waves. Here, it is hard to awake. Sleep spindles, K - complex are found in this stage, which helps in a deep sleep.
REM or rapid eye movement is a deep sleep stage. It is also called paradoxical sleep. Here, the brain is more active and the body is paralyzed. During this stage a person dreams.
Therefore, NREM (non rapid eye movement ) is the stage of sleep comes before REM sleep.

what is the tonicity of honey
Answer:
Is honey hypertonic?
Image result for what is tonicity of honey
Honey is 70 to 80% sugar and this high percentage causes hypertonic conditions that may lead to lysis of microbial cell walls.
Explanation:
hope this helps
Honey is hypertonic, meaning it absorbs water quickly. As a result, it can keep a tear dry and draw off the fluid that bacteria require to survive.
What is tonicity?Tonicity is a solution's ability to change the volume of cells by changing their water content. When water enters a cell, it can cause hypotonicity or hypertonicity when it exits the cell.
Hypotonic fluid contains less fluid, sugars, and salt than blood. Hypertonic fluid contains more fluid, sugars, as well as salt than blood.
Isotonic fluid, sugars, and salt concentrations are the same as those found in blood.
Honey is hypertonic, which means it quickly soaks up water. As a result, it can keep a tear dry as well as draw off the fluid required by bacteria to survive.
Honey has such potent antibacterial properties that it can treat severe conditions such as MRSA, which is recognized to be resistant to conventional antibiotics.
Thus, it can be concluded that honey is hypertonic.

The area around a charge in which the electric force is experienced by other charged objects is the ______________
The area around a charge in which the electric force is experienced by other charged objects is the electric field.
The electric field is a property of the space around a charged object and is created by the presence of that charge. Any other charged object placed within the electric field will experience a force exerted on it due to the interactions between the electric charges.
The electric field can be thought of as a field of influence that extends throughout space, representing the force that would be experienced by a positive test charge placed at any given point within the field. The strength and direction of the electric field depend on the magnitude and sign of the charge creating the field. Electric field lines, which are used to visualize the electric field, point away from positive charges and towards negative charges.
The electric field plays a crucial role in understanding and describing the behavior of charged particles and the interactions between them. It is a fundamental concept in electromagnetism and has applications in various fields, including electronics, electrical engineering, and physics.

where is mitochondria found abundantly between sperms and ova.Explain
Mitochondria are found abundantly in the midpiece of the sperm. The midpiece is located just behind the head of the sperm and contains many mitochondria that provide energy for the sperm to swim towards the egg. The egg, on the other hand, contains mitochondria throughout its cytoplasm. This is because the egg needs a large amount of energy to support the early stages of embryonic development, before the zygote can begin to produce its own energy.
During fertilization, the sperm and egg combine to form a zygote. The mitochondria from the sperm are typically destroyed after fertilization, so the zygote relies solely on the mitochondria from the egg for energy production. This is why mitochondrial DNA is inherited solely from the mother in most animals, including humans.
