Answer:
If a new predator were introduced to prey with which it has not coevolved, it could have a devastating effect on the prey species. The prey species may not have adapted behaviors or physical characteristics to protect themselves from the new predator, making them easy targets for predation. This could lead to a decrease in the prey population and an increase in the predator population, ultimately resulting in the destruction of the prey species. Additionally, the introduction of a new predator could disrupt the balance of the existing food web, which could have a ripple effect on other species in the ecosystem.
Explanation:
Answer: leading cause of extinction is the introduction of predators into an isolated system like an island or a lake

The plankton as a carbon sink and as a carbon source in the area will be less than expected.
The plankton as a carbon sink will be greater than expected, but the plankton as a carbon source
will be less than expected.
O The plankton as a carbon sink and as a carbon source in the area will be greater than expected.
This information might be used to draw the conclusion that there will be fewer plankton in the region than is typical both as a carbon source and sink, hence B is the appropriate response to this question.
What is phytoplankton?The kind of organisms that live in watery habitats are known as phytoplankton.
These species are autotrophic in nature and are the producers of this ecosystem. These creatures share a characteristic with terrestrial plants in that they both contain chlorophyll.
Therefore, if the phytoplankton population falls in the coming year, it means that the region's carbon supply and sink will be less than anticipated.

work from home will have a future impact on urban sprawl?
Answer:
Yes, working from home will have a future impact on urban sprawl. Working from home reduces the need for people to commute to their workplace, which in turn reduces the demand for housing in urban areas. This can lead to a decrease in urban sprawl, as fewer people are commuting to urban areas and thus fewer people are in need of housing. Additionally, with fewer people commuting to urban areas, there will be less traffic congestion, leading to a reduction in air pollution.

Evan was 54 meters away from his car adter shopping. It took 9 seconds to push a shopping card one third of the way directly to his car at a constant velocity. What was his velocity whilehe was pushing the cart ?
The velocity while Evan was pushing the cart is 50.15m/s.
How to calculate velocity?The velocity of a moving body can be calculated using one of the following equations of motion as follows:
s = ut + ½at²
Where;
s = distanceu = velocityt = timea = accelerationAccording to this question, Evan was 54 meters away from his car after shopping. It took 9 seconds to push a shopping card one third of the way directly to his car at a constant velocity. The velocity used is as follows:
54 = (u × 9) - ½ × 9.81 × 9²
54 = 9u - 397.31
54 - 397.31 = 9u
u = 50.15m/s
Therefore, 50.15m/s is the velocity while pushing the cart.

Evan's velocity while pushing the cart towards his car would be 2 m/s.
Velocity calculationThe velocity of a moving object is the speed of the object in a specific direction. Thus, velocity is the ratio of distance covered relative to time.
Mathematically, velocity = distance/time.
Evans took a total of 9 seconds to cover 1/3 of his distance from his car.
1/3 of 54 = 18 meters.
Thus, Evan covered a distance of 18 meters in 9 seconds. His speed can be calculated as follows:
Distance = 18 meters
Time = 9 seconds
Speed = 18/9
= 2 m/s
In other words, the velocity of Evan while he was pushing the cart is 2 m/s towards his car.

The movement of these tectonic plates is most likely caused by convection currents in the molten rock beneath the crust of the Earth. The immediate consequences of this tectonic shift are earthquakes and volcanic eruptions.
What effect does this plate movement have?Mountains will grow where plates converge or push together, and continents will split and oceans will form when plates pull apart or diverge. The Earth's geography has changed significantly over the span of millions of years as a result of the continents passively drifting with the plates.

Briefly, explain how Tiktaalik could have existed in this Canadian environment.
Tiktaalik, an extinct fish species, could have existed in a Canadian environment due to the presence of shallow freshwater environments with low oxygen levels, which would have been suitable for its lung-like structure and ability to breathe air.
What is Tiktaalik?Tiktaalik is an extinct genus of fish that lived about 385 million years ago during the Late Devonian period. It is considered a transitional fossil, as it has characteristics of both fish and early tetrapods, four-legged land-dwelling animals. Tiktaalik could have existed in a Canadian environment, as it is known to have been found in the Canadian Arctic, specifically in the Elpistostege watsoni fossil beds of the Nunavut territory.
The environment during Late Devonian period in this region was a shallow freshwater delta or coastal plain that was home to a diverse array of fish and other aquatic organisms. Tiktaalik likely lived in the shallow water, and had adaptations such as flexible neck and fins with bones that resemble the limb bones of four-legged animals, which would have allowed it to move in shallow water and on land.

A deer eats a leaf from a tree and gets energy from sugar molecules in the leaf. Which two organelles are required to make this process possible? Pls help thank u so much
Two organelles that are required to make the process of the deer obtaining energy from sugar molecules in the leaf possible are the mitochondria and the chloroplasts.
What is the function of mitochondria and chloroplast?Mitochondria are organelles found in the cytoplasm of eukaryotic cells and are responsible for generating the majority of the cell's energy. They do this through a process called cellular respiration, in which sugar molecules are broken down and the energy released is used to produce molecules of adenosine triphosphate (ATP), which the cell can then use as a source of energy.
Chloroplasts are organelles found in the cells of plants, algae and some other organisms that absorb light energy and convert it into chemical energy. They are only found in the cells that have green pigments called chlorophyll. Chloroplasts are the site of photosynthesis, the process by which plants and other organisms convert light energy into chemical energy by using carbon dioxide and water to produce glucose and oxygen.

At high altitudes, air temperature is also generally colder than at sea level.
D. Describe and explain one internal body response that occurs when a person has been outside long enough for his core temperature to drop.
Answer:
When a person has been outside long enough for their core temperature to drop, their body will respond by shivering. Shivering is an involuntary muscle movement that helps to generate heat and raise the core body temperature back to a normal level.
