Which finding would have disproved Virchow’s hypothesis?
1.) Animalcules are not organisms.
2.) Animals are made of non–cell-based matter.
3.) Plants are made of non–cell-based matter.
4.) Cells can generate from nonliving matter.
Answers
Answer:
Virchow was a German scientist whose most important work was in the filed of cellular biology and pathology.His scientific experiments and examinations aimed to disprove the idea of spontaneous generation. This idea is based on an assumption that life can spontaneously appear out of non-living matter. After years of scientific work he concluded that only living cells can produce other cells, or that only life can produce life.Therefore, if it was somehow proven that cells can be generated from non-living matter, that would disprove his findings.

Answer:
D. The process through which scientists review one another's work to
validate results and conclusions
Explanation:
Peer Review works on literary findings and not communication.
The process through which scientists review one another's work to validate results and conclusions, is the best definition of peer review. The correct option is D.
What is peer review?The system of peer review is employed to assess the merit of a manuscript prior to it being published.
Independent researchers in the relevant research area evaluate submitted manuscripts for originality, validity, and significance to assist editors in deciding whether to publish a manuscript in their journal.
Peer review is essentially an academic term for quality assurance. Each article that appeared in a peer-reviewed journal was thoroughly reviewed by a panel of experts on the topic of the article.
Peer review is meant to evaluate the validity, quality, and, in some cases, originality of articles submitted for publication. Its ultimate goal is to protect scientific integrity by filtering out invalid or low-quality articles.
Thus, the correct option is D.

Explanation:
An increase in the volume of forests and phytoplankton would lead to a reduction in free "blank" , which in turn could cause a decrease in carbon dioxide in the atmosphere.
Answers
Answer: Carbon dioxide
Explanation:
The forests and phytoplankton are carbon sinks, which absorbs the green house gas carbon dioxide from the atmosphere for photosynthesis. The carbon dioxide from the atmosphere and water are used as reactant in photosynthesis to yield carbohydrates and oxygen as products. Thus the carbon dioxide level in atmosphere decreases. This is necessary for controlling pollution in the environment and reducing the environmental temperature as carbon dioxide can make the environment warm.

single-celled organisms are able to maintain homeostasis even though they lack higher levels of organization such as organs and organ systems because...
Answers
Answer:
Because cells maintain homeostasis despite the amount.
Explanation:
When a change occurs in an animal’s environment, an adjustment must be made so that the internal environment of the body and cells remains stable. The receptor that senses the change in the environment is part of a feedback mechanism. The stimulus—temperature, glucose, or calcium levels—is detected by the receptor. The receptor sends information to a control center, often the brain, which relays appropriate signals to an effector organ that is able to cause an appropriate change, either up or down, depending on the information the sensor was sending.
Single-celled organisms are able to maintain homeostasis even though they lack higher levels of organization such as organs and organ systems because - all cell structures work together to maintain homeostasis.
Unicellular organisms like bacteria have various ways of maintaining homeostasis. There are various cellular structures and particles to maintain homeostasis. For example,
Bacteria also have sensors, a protein molecule, that sense and respond to toxic levels of heavy metals in the environment and also help regulate beneficial metal ions.Unicellular such as bacteria can control the lipid composition in their plasma membranes to regulate the permeability for substances to move in or out.Bacteria and paramecium are unicellular organisms that use contractile vacuoles to control the amount of water inside of them.Thus, Single-celled organisms are able to maintain homeostasis even though they lack higher levels of organization such as organs and organ systems because - all cell structures work together to maintain homeostasis.
