Answer:
C) Re-do the measurements, several times, and take the average density before making a decision.
Explanation:
For the correct identification of the metal, weather its nickel or copper, Carl should repeat the experiment several times and take the average density before making the decision. It is important because it reduces the chance of error and ensure the data integrity. The more the sample size is, lessen would be the error.
<u>Answer:</u>
Most plants, most algae and cyanobacteria kinds of organisms (Autotrophs) can perform photosynthesis while heterotrophs are organisms incapable of photosynthesis.
<u>Explanation:</u>
Photosynthesis is a mechanism used among plants as well as other species to transform energy from the sun into chemical energy which may be released later to power the functions of the species.
In autotrophs (organisms who self prepare there food ) with the support of a subsequent series of light-independent reactions like Calvin cycle, creates long-term energy collection in the form of sugars, while some bacteria use different mechanisms like the reverse Krebs cycle to accomplish the same purpose.
Heterotrophs are entities unable to photosynthesize and, by eating certain species, must therefore obtain energy and carbon from the food. In the term heterotroph: hetero means "other" while troph means "feeder", thus their food depends on other species.
Answer:
A species that has homologous chromosomes is known as a diploid species. Homologous chromosomes are chromosomes that come in identical pairs.Ê
Explanation:
the answer is true that 50% ecosystems are currently being used unendurable.
OK so basically they use binary fission to into two halves producing two new cells.
