Students in a science class visited four local ecosystems. The students observed the species present in each ecosystem and recorded their observations in the table.


Based on these observations, which ecosystem is likely to be the least sustainable?

A.Ecosystem 1, because it has the fewest species
B.Ecosystem 2, because it includes both aquatic and terrestrial species
C.Ecosystem 3, because it has few predators
D.Ecosystem 4, because it supports many animals

Answer:

The answer is D Each part is connected to all the others

Explanation:

While each part is different they interact with eachother to exchange matter and make life possible :) Hope this helps!

The true statement among the given options of the many parts of the biosphere is option D. Each part is connected to all the others.​

The biosphere is the ecosphere consist of air, land, water, and rocks all parts where life is found or possible. It is made up of parts of all ecosystems where life exists on earth.

The biosphere has three major parts that interact with one another where life is found:

All these parts are interconnected with other parts of the biosphere there are no isolated parts.

Thus, the correct answer is - D. Each part is connected to all the others.​

Answer:

Honestly I think it's C

Explanation:

The three main ocean zones are neritic, bathyal, and abyssal. Therefore, none of the statements are correct.

The ocean is divided into three main zones which are the neritic zone. This zone is the shallowest zone extending from the shoreline to the edge of the continental shelf and is 200 meters deep.

The bathyal zone is the middle zone extending from the edge of the continental shelf to the abyssal plain and is 4,000 meters deep. The abyssal zone is the deepest zone extending from the abyssal plain to the ocean floor.

Apart from the three main ocean zones, there other oceanic zones are  epipelagic zone, mesopelagic zone, and hadal zone. The hadal zone is the deepest oceanic zone and is unique to highly adapted species of marine life and is important to study.

Therefore, the three main ocean zones are neritic, bathyal, and abyssal.

Lipids (Fats)

Answer:

Answer:

e. Nutrient runoff from agriculture fertilizers, manure, and urban sources, which leads to rapid algal growth and subsequent bacterial decomposition

Answer:

 Explanation:

Run off from agricultural wastes which contain Nitrogen and Phosphorus are the major sources  causes dead zones.The process where these chemical get washed into the aquatic bodies is called Eutrophication.

These substances leads to algae boosts in the water.The increases population of the algae consumes the available oxygen in the water, therefore making the oxygen concentration drops or no oxygen at all;(Hypoxia)

As the algae population feed on the available resources in the water they exhausted this,and later die.

When the decomposing bacteria used the oxygen in the water to breakdown the dead algae they make use of the available oxygen.This further reduced the oxygen availability and therefore   reduces the oxygen and hence the zone becomes the dead zone, because little or no oxygen is available  for survival of organisms.

This is reversible if the process if europhication or other causes  is eliminated

The group of choices associated with the question is:

Tyr-Phe-Glu-Asn-Leu

Met-Phe-Pro-Ile-Leu

Val-Ala-Val-Glu-Val

Glu-Asn-Ser-Thr-Gln

Answer:

The correct answer is - Met-Phe-Pro-Ile-Leu

Explanation:

There is various type of amino acid residues that are located in the water-soluble globular protein, depend on the location inside the globular protein, that could be the center of the particular protein or interior of the protein.

Met-Phe-Pro-Ile-Leu  is the amino acid residue among given options is the most likely the sequence as all the amino acids are nonpolar in this residue.

Thus, the correct answer is - Met-Phe-Pro-Ile-Leu

The amino acids that would be buried will be Met-Phe-Pro-Ile-Leu.

Amino acids simply refer to the organic compounds that contain amino and carboxylate functional groups. They're the molecules that combine in order to form proteins.

From the complete information, it should be noted that globular proteins are folded in such a way that their tertiary structure consists of hydrophilic, amino acids, arranged on the outside. From the options given, the amino acids that would be buried in the interior of a water-soluble globular protein will be Met-Phe-Pro-Ile-Leu.

Answer:

The side groups are what make each amino acid different from the others. Of the 20 side groups used to make proteins, there are two main groups: polar and non-polar. These names refer to the way the side groups, sometimes called "R" groups, interact with the environment.

Answer:

The new solution has a higher concentration than the isotonic saline solution

Explanation:

Here, we want to deduce what has happened in the question.

We are told that the level of the isotonic saline solution dropped because it was connected an unknown solution using a semipermeable membrane.

Since the level of the solution dropped, then it must have occurred that there has been the loss of some of the molecules of the solution.

What has occurred is the process of Osmosis

Osmosis simply involves a movement through a semipermeable membrane of solvent molecules due to the fact that the previous solution is of lower concentration than the present one.

So what we can see here is that there has been a movement due to osmosis as a result of the fact that the new solution has a higher concentration than the former one

Explanation:

The interactions between human population dynamics and the environment have often been viewed mechanistically. This review elucidates the complexities and contextual specificities of population-environment relationships in a number of domains. It explores the ways in which demographers and other social scientists have sought to understand the relationships among a full range of population dynamics (e.g., population size, growth, density, age and sex composition, migration, urbanization, vital rates) and environmental changes. The chapter briefly reviews a number of the theories for understanding population and the environment and then proceeds to provide a state-of-the-art review of studies that have examined population dynamics and their relationship to five environmental issue areas. The review concludes by relating population-environment research to emerging work on human-environment systems.

Claim-Evidence-Reasoning

Explanation:

hope it helps

Answer:

CER(S) Stands for Claim, Evidence, Reasoning, Science

Explanation:

The 1st part of CER(S) is a CLAIM. A claim is a simple, single sentence that answers a question. Your claim is a statement about what you believe to be true about that question. Your claim must be accurate, clear, and exact. Your claim should be the first sentence in your explanation. Your claim should ONLY answer the question – do not explain your answer at this point.

The 2nd part of CER(S) is EVIDENCE. Evidence consists of data and/or results that can be used to support the claim. Evidence must be explicitly stated in sentence form and cannot merely be referenced. To adequately support a claim, the evidence must be appropriate (relevant to the question) and sufficient (enough provided to be convincing).

The 3rd part of CER(S) is the REASONING. Reasoning ties the evidence to the claim and explains why the evidence supports your claim.  In this section you discuss why the evidence that you provided is important and relevant to your claim.  

The 4th and final part of CER(S) is the SCIENCE. Your teacher may not ask you to provide the supporting science for every CER(S) question – that is why the S is in parentheses. If you are asked to provide the science that supports your claim, then you need to discuss the relevant science and how it supports your claim.

Explanation:

Meiosis is the cell division that involves the production of daughter cells or gametes with a reduced number of chromosomes. i.e. diploid (2n) - haploid (n).

According to Gregor Mendel in his law of Segregation, the alleles of a gene will separate into gametes in such a way that only one allele will be present in each sex cell. Hence, in this diploid cell with genotype AaSs, the alleles will separate into the haploid cell in the following genotype proportion:
