Of the options listed, we can confirm that the best evidence to support the claim that global warming has a long-term impact on the ecosystem is given by the phrase "Habitat loss would occur, leading to a decline in species diversity".
<h3>How does habitat loss affect ecosystems?</h3>
- Habitat loss can decrease the species diversity in an ecosystem.
- This can have dire consequences.
- One such consequence is the <u>reduction </u>of primary consumers or producers.
- This decrease in food supply can cause the collapse of the food chain and the disappearance of the ecosystem as a whole.
Therefore, given that the increased temperatures will cause habitat loss, this will lead to a sharp decrease in biodiversity, meaning possibly fewer producers or primary consumers to maintain a stable food chain. This can lead to the full collapse of an ecosystem.

Answer:
The Nucleus
Explanation:
The Nucleus is an organelle enclosed in a nuclear membrane present in all Eukaryotic. It controls the activities of the cell by regulating the expression of genes in the Deoxy ribosenucleic acid (DNA) stored in it. It controls the hereditary traits of an organism by regulating cell division.
It harbors the nucleolus, which contains the Ribosenucleic acid (RNA) that conveys the instructions in the DNA and also serves as a template for protein synthesis (responsible for phenotypic traits) in the ribosome.
Mitochondria is the organelle which releases energy for metabolic activity in cells
Answer: 10. Control Group
11. Identify the:
Control Group = Subject A
Independent Variable = The new and original itching powder.
Dependent Variable = The type of itchiness.
Explanation: The Control Group is NOT affected by the experiment. Subject A was given the original itching powder and is not being experimented on with the new itching powder, therefore, Subject A is the Control Group.
The Independent Variable is what you can CHANGE. You control the two itching powders, so you decide which one you give to who. This makes the two itching powders the Independent Variable.
The Dependent Variable DEPENDS on the effects of the Independent Variable. This is what you cannot change, the results. In this case, the type of itchiness experienced and the amount of itchiness experienced cannot be changed, it is a result of the powders, hence why it is the Dependent Variable.
Estrogens are hormones that are play important roles in the reproductive system.
<h3>What are the roles played by estrogen?</h3>
The environmental estrogen introduced to the male cells has the ability to recognise the binding sites of the receptors on the male cells.
They are able to attach the the cell membranes by its ability to bind to the cell receptors.
When the binding occurs, there would be a conformational change within the cell leading to:
- modulation of protein synthesis and
- development of the female secondary reproductive characteristics.
