Explanation:
The electron is.
The electron is the subatomic particle most famous for characteristic behaviors observed in the context of chemical bonding.
Answer:
On the basis of Chargaff's rule, in a double-helical DNA, A = T and G = C (Here A means adenine, T means thymine, G means guanine, and C means cytosine. For X, A is given 32%, therefore, T must be 32%, and the leftover 36% is to be distributed equally between G and C. Thus, G = C = 18% each.
The assumption formed is that the DNA is a double-stranded structure. The species that exhibits higher G + C content in the molecule of a DNA is steadier at higher temperatures as it melts at high temperature. The species Y, which exhibits G + C in total as 66% is the thermophilic bacterium between the two.
Answer:
- Oak trees: primary producers
- Caterpillars: primary consumers
- Blue Jays: secondary consumers
- Hawks: tertiary consumers
Explanation:
A trophic pyramid, also known as ecological pyramid or energy pyramid, is a graphic representation that shows the relationships between different types of organisms (i.e., producers and consumers) at the trophic levels of an ecosystem. The primary producers are autotrophic organisms that obtain energy from sunlight and chemical compounds from nonliving sources (e.g., photosynthetic plants, algae, etc). The primary consumers are organisms that eat primary producers (e.g., herbivores), while secondary consumers are organisms that eat primary consumers (e.g., omnivores). Moreover, tertiary consumers are predators and/or omnivores that eat secondary consumers (e.g., hawks). Finally, decomposers (e.g., bacteria) are organisms that obtain nutrients and energy by breaking down dead organic material (i.e., dead organisms) at all trophic levels into nutrients.
