Why would an ecologist study a community instead of a population?

to see how lots of organisms live in the same place at once, even though they don’t affect each other

to see how members of the same species are similar to—or different from—each other

to see how different types of organisms in the same area will affect each other

to see how a change in the environment affects one of the species living in it

Answer:they would die

Explanation:

because

Upon inhalation, the diaphragm contracts and flattens and the chest cavity enlarges. This contraction creates a vacuum, which pulls air into the lungs. Upon exhalation, the diaphragm relaxes and returns to its domelike shape, and air is forced out of the lungs. Without a diaphragm, this process wouldn’t work and a person could not breathe.

In recent years, there has been a significant shift towards renewable energy sources in many countries, as they are becoming more cost-effective and environmentally friendly compared to traditional fossil fuels. The most common renewable energy sources are solar, wind, hydroelectric, geothermal, and biomass.

Solar energy is one of the most rapidly growing renewable energy sources worldwide. It has already become affordable for households and businesses to install solar panels, which are increasingly being used to generate electricity. In many communities, solar farms are also being established to supply power to the grid. With the advancement in technology, the efficiency of solar panels is improving, and the cost of installation is decreasing, making it a more viable option for more households and businesses.

Wind energy is another renewable source that is increasingly being utilized. Wind turbines are being installed in many areas, especially in regions with consistent winds. As with solar energy, advances in technology are leading to improved turbine efficiency and lower installation costs.

Hydroelectric energy is a well-established source of renewable energy that has been in use for many years. Many countries have already established hydroelectric power plants, and more are being constructed. While the construction and operation of these plants can have some environmental impacts, hydroelectricity is a clean and reliable source of energy.

Geothermal energy is another renewable source that has great potential. It involves extracting heat from the earth's core to generate electricity. While currently geothermal energy is not widely used, there is increasing interest in it as a source of clean and renewable energy.

Biomass energy involves using organic materials such as wood chips, crop waste, or even animal manure to generate electricity. While this source of energy is not as clean as some of the others, it can be a good option for communities that have access to a lot of biomass waste.

In conclusion, the most likely source of renewable energy to be used in a community will depend on a variety of factors, including the availability of resources, local government policies, and technological advancements. However, solar and wind energy are likely to become more popular due to their increasing affordability and efficiency, as well as their potential for use at a household or small business level.

Answer: Electricity is the renewable energy source likely to be used within the next 20 years.

Explanation:

These days electricity is reaching far and wide corners of the country, with this fast growth the future is electric. The growing craze for electric cars, electric cars, and other electrical appliances electricity demand is increasing.

Electricity is easy to produce with the use of hydropower plants and windmills. It is most likely to take over the future.

balanced, which means that the forces pushing the rock in one direction are equal to the forces pushing the rock in the opposite direction. This is why the rock remains motionless on the flat sidewalk.

It is balances because nor is it being pulled or pushed.

Answer:

W

Explanation:

Gravitational force is calculated by (m₁ * m₂)/d² where d is the distance, m₁ is the mass of one object and m₂ is the mass of another. Let's set m₁ to the mass of the star. Since the gravitational force we are trying to calculate is between the star and each object, the number amount of the star's mass is not required. Additionally, all objects are the same distance from the star, so distance measurements do not matter. All we have to do is compare the masses. By using the equation, logically, greater masses should yield a larger gravitational force. Thus, since W has the greatest mass, it must have the strongest gravitational force of attraction with the star.

Answer:

C) W

Explanation:

(m1 * m2)/d2, where d is the distance, m1 is the mass of one item, and m2 is the mass of another, is the formula for gravitational force. Let's put m1 equal to the star's mass. The mass of the star is not necessary since the gravitational force we are attempting to compute is between each item and the star. Distance measurements are also irrelevant because all objects are at the same distance from the star. To compare the masses is all that is necessary. Using the equation, more masses should theoretically result in a stronger gravitational pull. W must thus have the biggest gravitational pull on the star since it has the most mass.

Answer and Explanation (QUESTION — 1):

During El Niño, the ocean's surface in the western pacific becomes warmer than usual, and the winds push the warm ocean currents toward the east. This movement allows the warm ocean current to meets with the cold ocean currents in the atmosphere that disrupts the weather pattern.

During El Niño, the western Pacific ocean’s surface tends to become warmer than the usual. Then, the winds push the warm ocean currents toward the east. This movement disrupts the weather patterns once it meets with the cold ocean currents.

Answer and Explanation (QUESTION — 2):

El Niño causes the Pacific jet stream to move south and spread further east. During winter, this leads to wetter conditions than usual in the Southern U.S. and warmer and drier conditions in the North. El Niño also has a strong effect on marine life off the Pacific coast.

El Niño conditions can cause a wide range of health problems, including disease outbreaks, malnutrition, heat stress, and respiratory diseases. El Niño has an impact on ocean temperatures, the speed and strength of ocean currents, the health of coastal fisheries, and local weather from Australia to South America and beyond. El Niño events occur irregularly at two- to seven-year intervals.

Answer and Explanation (QUESTION — 3):

Winds blowing across the ocean surface often push water away from an area. When this occurs, water rises up from beneath the surface to replace the diverging surface water. This process is known as upwelling. Upwelling occurs in the open ocean and along coastlines.

The three main drivers that work together to cause upwelling are wind, Coriolis effect, and Edman transport. The deeper water that rises to the surface during upwelling is rich in nutrients. These nutrients “fertilise” surface waters, encouraging the growth of plant life, including phytoplankton.

Upwelling also occurs in El Niño.

Answer and Explanation (QUESTION — 4):

As a result, these fishes may either die or swim to other places. In this case, predicting El Niño would be helpful for people, especially those who rely on fishing for their livelihood, to be better prepared for the arrival of this climate event in order to reduce its impact.

The fishermen who handle the waters of the Pacific off the shore of Peru and Ecuador have known for a considerable length of time about the El Niño. Each three to seven years amid the periods of December and January, angle in the waterfront waters off of these nations basically vanish, making the angling business grind to a halt. South American anglers have given this wonder the name El Niño, which is Spanish for "the Boy Child," since it happens the season of the festival of the introduction of the Christ Child. Amid an El Niño, the physical connections between wind, sea streams, maritime and environmental temperature, and biosphere separate into dangerous examples that are second just to the walk of the seasons in their effects to climate conditions the world over.

El Nino is known in coasts of Peru and Ecuador. Every 3 to 7 years (in the months of December and January), this phenomenon occurs causing the fish to virtually disappear or vanish from the water. This leads to a deterioration in the fishing industry. Being able to predict El Nino would help fisher men a lot as it will give them an idea of when this phenomenon will occur. Therefore, they would be able to plan for the season accordingly as they would know when to expect the disappearance of the fish from the coasts.

Hope my answer helps you.

Please mark my answer as the BRAINLIEST. Plssssssssssssssssssss

I wrote a higher grade answers.

Please forgive me if you fell my answer is difficult to understand.

You can write easy points. But mention the main and important points.

What effect does El Nono have on weather and climat

1. Mitosis and meiosis are two processes involved in cell division in human cells, but they have several differences and similarities.

Similarities:

Both processes involve the duplication of genetic material, including the chromosomes.
Both processes occur in eukaryotic cells.
Both processes are preceded by the replication of DNA.
Differences:

Mitosis is a process of asexual reproduction, while meiosis is a process of sexual reproduction.
In mitosis, one cell divides into two identical daughter cells, while in meiosis, one cell divides into four genetically diverse daughter cells.
Mitosis occurs in all somatic cells, while meiosis occurs only in germ cells.

2. A homozygous dominant genotype is when an individual has two copies of the same dominant allele for a specific gene. In genetic notation, it is represented by two capital letters, such as "AA". This individual will express the dominant trait because the dominant allele masks the effect of the recessive allele.

A homozygous recessive genotype is when an individual has two copies of the same recessive allele for a specific gene. In genetic notation, it is represented by two lowercase letters, such as "aa". This individual will express the recessive trait because there is no dominant allele to mask its effect.

3. A heterozygous genotype is when an individual has two different alleles for a specific gene, one dominant and one recessive. In genetic notation, it is represented by one capital letter and one lowercase letter, with the capital letter representing the dominant allele and the lowercase letter representing the recessive allele. For example, "Aa" is a heterozygous genotype, where "A" is the dominant allele and "a" is the recessive allele.

a homozygous dominant would look like this: AA
a homozygous recessive would look like this: aa

and a heterozygous genotype would look like this: Aa

i cant answer the second question, but i hope that could help ;)
