Answer:
B
Explanation:
If it is denser it will more likely sink because of convection currents forcing it down.
The dermis is the skin area along a central nerve pathway
Mechanical energy converting to chemical energy.
Answer:
Autotrophs
Explanation:
Autotrophs are organisms that use energy directly from the sun or from chemical bonds. Commonly called producers, they use the energy and simple inorganic compounds to produce organic molecules. Autotrophs are vital to all ecosystems because all organisms need organic molecules and only autotrophs can produce them from inorganic compounds. There are two basic types of autotrophs: photoautotrophs and chemoautotrophs.
Photoautotrophs
Photoautotrophs are autotrophs that use energy from sunlight to make organic compounds by photosynthesis. Photoautotrophs include plants, algae, and many bacteria, as shown in the figure below. They are the primary producers in the vast majority of ecosystems on Earth.
Chemoautotrophs
Chemoautotrophs use energy from chemical bonds to make organic compounds by chemosynthesis. Chemoautotrophs include certain bacteria and archaeans. They are the primary producers in ecosystems that form around hydrothermal vents and in hot springs.
An experiment is reliable when its repetition produce always the same result. In science, peer review is fundamental because this process ensures that there is not misleading data that may lead to erroneous results.
- In sciences, reliability is a term used to evaluate the quality of research. Reliability refers to the probability that an experiment or result is correct, thereby preventing and mitigating failures over time.
- An experiment whose successive repetitions conduct the same result is 100% reliable.
- Three examples of reliability in science:
- the same measurement of the size of the leg of a spider.
- the observation of the same behavior of birds populations on different days and at different times of the day.
- the same byproducts from a given chemical reaction when an experiment is repeated two or more times.
- Peer review is the most widely accepted process used to validate scientific data. This process (peer review) is fundamental to facilitate the growth of scientific knowledge.
- During peer review, independent scientists assess the originality, reliability, and significance of a scientific work before its publication.
