This is a biome.

Biomes really do cover large areas, for example there is one biome stretching from France to central Russia (temperate broadleaf forrest). They are characterized by a similar soil and a shared community of animals and plants.

Which is not a major similarity or difference between freshwater and marine ecosystems? I believe its b a. both support a large number of plants and animals adapted for aquatic living b. ocean and freshwater system conditions generally remain constant throughout the year c. freshwater ecosystems have a very low salt concentration, and include ponds, lakes, streams, wetlands, and rivers d. saltwater ecosystems have a high salt concentration and include oceans, coral reefs, and estuaries

The correct answer is:

b. ocean and freshwater system conditions generally remain constant throughout the year .

Explanation:

ocean and freshwater system requirements frequently remain constant completely the year. This is not true because they are very inconsistent. For examples, freshwater rivers can completely freeze during the winter while oceans can't freeze entirely, not even a bit. Also, the animals inside have radically changed body structures to fight these changes.

Scientific consensus supports the idea that living organisms require oxygen. Then, a scientist discovers a type of bacteria that metabolizes sulfur instead of oxygen, and thus survives in environments without oxygen. The scientist concludes that a diverse group of many different organisms could live in an oxygen-free environment. Why should are some scientists skeptical of the scientist’s results and conclusion?

The answer is that the conclusion needs to be supported by more evidence.

It is not enough to find some type of bacteria that can live in an oxygen-free environment to conclude there are many different organisms that also can. It is necessary to know what mechanisms of the organisms are responsible for such characteristics that help them  survive in environments without oxygen. There must be more evidence from different group of organisms that will confirm the conclusion.

Scientists group organisms into kingdoms by looking at specific characteristics. Which is a characteristic of a carrot plant? no cell walls heterotrophic unicellular eukaryotic

Scientists group organisms into kingdoms by looking at specific characteristics. The characteristic of the carrot plant is eukaryotic. Organisms with eukaryotic cells are whose cells contain a nucleus and other organelles enclosed within membranes.

Explanation:

Eukaryotes are organisms whose cells have a nucleus surrounded by membranes, unlike prokaryotes. Eukaryotic cells are larger than prokaryotic cells and have a “true” nucleus, membrane-bound organelles, and rod-shaped chromosomes. The nucleus houses the cell's DNA and regulates the structure of proteins and ribosomes.

Biologists believe that a large number of species that are part of the rain forest ecosystem are on the verge of extinction. Which statement BEST describes the role of urbanization in this disaster? A) Urbanization leads to deforestation and loss of habitat for many species. B) Many animals are captured or killed by poachers, significantly reducing their numbers. C) Viral epidemics that break out in human populations spread to animals in the ecosystem. D) Factories cause a significant rise in temperature in the forests, endangering many species.

Answer: A) Urbanization leads to deforestation and loss of habitat for many species.

Explanation:

Urbanization is the main reason for the exploitation of the rain forests which has lead to the extinction of species used to be residing in the forests ecosystems.  Following are the factors which are responsible for such disaster with the expension of urbanization:

1. Infrastructure: The land is the main requirement which is responsible for the exploitation of rain forests. The large area is required for the accommodation of  the large human population, construction of roads, highways and bridges. This has replaced many habit-ant animals from their native land and also leads to extinction due to ecological disturbance.

2. Increasing needs of food, herbs and wood: Many species of wooden trees could be found in the rain forests which have now extincted due to increasing demand for wood. The herbs have been wiped up for the preparation of medicines and drugs. The large number of tree populations are also exploited due to availability of fruits, and vegetables.

3. Wildlife trafficking and hunting: Some of the animal species have been included in the list of endangered species due to their use for commercial selling of horns, hives and other valuables.

The end of the Triassic period was possibly caused by the large______ zone that developed due to Pangaea breaking up a. rift b. volcanic

a. rift

The Triassic Period indicated the commencement of significant developments that were to take place everywhere in the Mesozoic Era, individually in the administration of regions, the development of life, and the geographic concentration of living things.

At the conclusion of the Triassic, the supercontinent of Pangea, which consolidated all of the modern regions into a single landmass, started to split (rift) apart. As North America segregated from Africa and the Atlantic Ocean started to form, volcanic activity on a comprehensive scale originated carbon dioxide into the environment. This led to global warming and modifications to the oceans that were comparable to those that happened at the end-Permian extirpation.

Scientists use specific levels of organization to analyze the biosphere. Which level of organization is seen in both a school of anchovies and a gaggle of geese? A. ecosystem. B. community. C. population. D. biome

The correct answer is C. population

In biology,the term population signifies a group of individuals of the same species that live in the same place and are able to successfully reproduce among each other. Like in our example with the school of anchovies and a gaggle of geese.

A community is formed by multiple populations of the same species in an ecosystem. Therefore, 3 different gaggles of geese, or schools of anchovies would form a community of geese or anchovies.

In your own words, give two reasons why it is important to keep your work area clean while completing a lab.

This should be from YOUR point of view since it's basically what you understand from consequences of not being safe.

ANSWER: It is important to keep the work area clean while completing a lab because it would not be safe for the ingredients within the experiment to mix with different components that do not belong in a lab. This could damage the area around you if you are not careful. The other reason why is because you do not want a different outcome from the experiment expected if it is combined with any other ingredient.

Johannes wants to know whether soil, water, or both are needed for plant growth. He chooses to conduct experiments on a willow tree for five years to answer his question. How can his experimental methods be changed to improve his experiment? A) He needs to ask scientists what they think. B) He needs to conduct the experiment for a longer period. C) He needs to use a larger sample size. D) He needs to test more factors in the environment.

The answer is C) He needs to use a larger sample size.

The results will be more accurate if there is a larger sample size. No matter the research, the larger sample size is, the more accurately will be the results and vice versa. The larger samples increase a chance of significance because they reflect the population mean more reliably. With a small sample, the chance for false conclusions is higher.

Johannes chose only one willow tree for five-year-experiment. The only one tree cannot represent a whole population. He should choose more trees in order to have better results about effects of different factors on plant growth.

Greg and Andrea are trying to find out how long it takes amylase, a digestive enzyme found in saliva, to break down a sample of starch. They put their sample in a beaker and covered it with their own saliva. After allowing it to sit on the lab table for 1 hour they measured the remaining surface area of the starch. What is the best way they could improve their experiment?

The answer is: the amount of the saliva samples must stay consistent while the amount of starch must vary.

The amount of the saliva samples must stay consistent because amylase, present in the saliva, is the independent variable which affects the dependent variable - the amount of starch. So, amylase will do its job while remaining surface area of the starch will depend on the starting amount of the starch.
