If the American alligator is a keystone species, then the ecosystem with alligators present will be healthier and contain greater biodiversity.

The diversity of living organisms on Earth, including plants, animals, microbes, and fungi, is referred to as biodiversity.

The Earth's biodiversity is so diverse that many species are still undiscovered, but because of human actions, many species are facing extinction, endangering the Earth's amazing biodiversity.

The vast variety of life on Earth is referred to as biodiversity. It can be applied more precisely to all the species found in a certain area or environment. Every living creature, including plants, microorganisms, animals, and people, is referred to as biodiversity.

Option b

Explanation:

An unbalanced force moving everyone in Daniel and Maria's direction

Answer:

Excitation is the process in which action potentials in the nerve fiber lead to action potentials in the muscle fiber. There is then a rapid fluctuation in membrane voltage at the motor end plate, called the end-plate potential. Areas of the sarcolemma near the motor plate have gates that open, moving ions, which causes the action potential that excites the muscle fiber. The process begins with a nerve signal stimulating a voltage-gated calcium ion channel to open, allowing the ions to enter the axon terminal. The ions stimulate the release of acetylcholine into the synaptic cleft.

Answer:Pioneer species

Explanation: Pioneer species are the first species to live in an area after it has been destroyed as mentioned.

The phylum Arthropoda contains a wide diversity of animals with hard exoskeletons and jointed appendages. Many familiar species belong to the phylum Arthropoda—insects, spiders, scorpions, centipedes, and millipedes on land; crabs, crayfish, shrimp, lobsters, and barnacles in water (Fig. 3.72).

The pollutants associated with the high tech-gadgets or e-waste include mercury, lead, cadmium, etc. So the correct answer is option C.

An electronic device that has reached the end of its usable life cycle is called as the electronic waste or the e-waste. The electronic waste contains a lot of toxic compounds inside them and should be handled carefully because this e-waste releases the toxic pollutants in the environment which can cause air pollution and also has an impact on respiratory health.

Burning of e-waste can release fine particles (pollutants) into the enviroment which can cause chronic diseases and cancers as well.

Answer:

feeding

Explanation:

when an organism eats another, it gets energy from it. That energy is passed along the food chain

The process by which energy is transferred from organisms at one stage in a food chain to organisms at the next is by feeding, which is present in the second option, as through the eating process and the predator-prey relationship, energies pass.

The food chain in nature is made up of many trophic levels, where one trophic level animal preys on other animals or plants and obtains food from them, so when the animal is eaten by other animals, the energy content passes from one to another, and the energy content from plants continues to decrease to the topmost trophic levels.

Hence, the process by which energy is transferred from organisms at one stage in a food chain to organisms at the next is by feeding, which is present in the second option, as through the eating process and the predator-prey relationship, energies pass.

The history of Mount Rainier's eruptions can help you decide whether hiking around Mount Rainier is safe by providing information about the volcano's past activity, eruption patterns, and potential hazards.

The history of Mount Rainier's eruptions provides valuable insights into the volcano's behavior and can help assess the safety of hiking around the area. By studying the volcano's eruption history, scientists and authorities can gather data on the frequency, magnitude, and types of eruptions that have occurred in the past.

This information is crucial for understanding the potential hazards associated with the volcano. For example, if Mount Rainier has a history of frequent and large explosive eruptions, it may indicate a higher level of risk for hikers due to the potential for ashfall, pyroclastic flows, or lahars (volcanic mudflows) that can pose dangers to human life.

Additionally, analyzing the timing and recurrence intervals of past eruptions can help estimate the likelihood of future eruptions. If the volcano has been relatively inactive for an extended period, it may suggest a lower immediate risk for hikers. However, it is essential to consider the potential for future eruptions and monitor any signs of volcanic unrest or changes in activity.

Furthermore, studying the extent and distribution of past volcanic deposits, such as lava flows or ash layers, can help identify areas that are more prone to hazards. This information can be used to establish exclusion zones or restrict access to certain hiking trails that may be closer to potential hazards.

Ultimately, by considering the history of Mount Rainier's eruptions and the associated hazards, authorities can make informed decisions regarding the safety of hiking around the volcano. It is crucial for hikers to stay updated with the latest information from local authorities, volcanic monitoring agencies, and park management to make responsible choices and ensure their safety when exploring the area.

Answer:

The amount of food in the area decreased, causing more chipmunks to

survive to reproductive age.

Explanation:

Hope this helps :)

Chipmunks in later generations showed greater genetic diversity than previous generations, allowing for a greater survival rate in later generations. Individual chipmunks changed their genetic makeup and became more successful in the environment. The correct options are R and S.

Genetic diversity refers to the total number of genetic traits that make up a species' genetic composition.

It varies greatly depending on the number of species present as well as across species, and it can be linked to a species' longevity.

DNA contains all the biological information and variety required to sustain life on our planet.

Genetic variety is referred to as this. It improves a species' and population's resistance to maladies, pests, climatic changes, and other pressures.

According to the findings, Chipmunks had a higher genetic variety in later generations than in earlier generations, which allowed for a higher survival rate in later generations. Individual chipmunks altered their genetic make-up and improved their chances of survival.

Explanation:

The main artery from the heart (aorta) becomes thicker, stiffer, and less flexible. This is probably related to changes in the connective tissue of the blood vessel wall. This makes the blood pressure higher and makes the heart work harder, which may lead to thickening of the heart muscle (hypertrophy).

Answer:

Transporte activo.

Explicación:

El transporte activo ocurre cuando una molécula se mueve de un área de menor concentración de sustancias a un área de mayor concentración. Los transportes activos utilizaron energía en forma de ATP para mover moléculas en contra del gradiente de concentración. Es lo opuesto al transporte pasivo en el que no se requiere energía para mover moléculas de una región a otra. La principal razón de que ocurra el transporte activo es que mueve moléculas en contra del flujo de difusión. En difusión, la molécula se mueve de un área de mayor concentración a un área de menor concentración.

Answer:

Core body temperature The body can only stay at a constant temperature if the heat generated is balanced and equal to the heat lost. Although the core temperature must be close to 37°C, fingers and toes can be colder. This is because energy is transferred from the blood as it travels to the fingers and toes.

Answer: When heat activates sweat glands, these glands bring that water, along with the body's salt, to the surface of the skin as sweat. Water evaporating from the skin cools the body, keeping its temperature in a healthy range.
