How can the introduction of a new species into an area effect the land, the flow of water,
the atmosphere, and/or the other living things?

Answers

The ecosystem's natural resources and human usage of those resources may be harmed by invasive species.

How can new species affect the ecosystem?

Animals or plants that are invasive are those from another part of the planet that don't belong in their new habitat. Ship ballast water, an unintentional release, and individuals are the most common ways that they are introduced to an area. Invasive species have the potential to wipe out native species, wipe out biodiversity, and irreversibly modify environments.

The ballast water of oceangoing ships, purposeful and unintentional discharges of aquaculture species, aquarium specimens or bait, and other methods can all be used to introduce an invasive species to a new location.

Native plants and animals may go extinct as a result of invasive species, which can also decrease biodiversity, compete with native species for scarce resources, and disrupt habitats. Ecosystems along the coast and in the Great Lakes may be severely disrupted, with significant negative economic effects.

D, the large bodies of water take a while to warm in cool because it takes more energy to heat the water, so the water usually stays around the same temperature. This also means cities near large bodies of water don’t vary much in temperatures. I hope that helps.

Describe in details the problem of replication at the end of Eukaryotic chromosomes and how cells solve this problem in details? you may draw your own illustrations

Answers

Answer:

These chromosomes have ends that pose a problem for DNA replication as this DNA cannot be fully copied at each step of the replication.

Eukaryotes have solved this problem by locating highly repeated DNA sequence at the end of each of the chromosomes.

Explanation:

The Eukaryotic chromosomes are linear and rod-shaped. These chromosomes have ends that pose a problem for DNA replication as this DNA cannot be fully copied at each step of the replication. This leads to a gradual shortening of the Eukaryotic chromosomes. However, Eukaryotes have solved this problem by locating a highly repeated DNA sequence at the end of each of the chromosomes.

The map displays The rate of population change in United States between the year 2010 and 2014 based on the map which of the given TWO states show the largest increase in population



Texas


South Carolina


Colorado


North Dakota

Answers

Texas and North Dakota are the TWO states to show the largest increase in population, shown in the map. Hence, option A and D are correct.

What is the reason of increasing population in Texas?

Texas has traditionally drawn both immigrants and citizens of the United States due to its wealth in natural resources, abundance of land, central location within the country, and welcoming business climate. As a result, the state's population is younger, more diversified, and rising more quickly than the rest of the country.

According to the Census Bureau, Texas experienced tremendous growth in 2018 and is home to half of the counties with the highest net population gain between 2020 and 2021. Austin experienced the fourth-highest rate of growth in the nation, falling behind the No. 1 Dallas-Fort Worth metro area.

Thus, option A and D are correct.
