Answer:
1. Habitat: Histosols are found in grasslands, swamps, and marshes, while aridosols are prevalent in arid environments like deserts.
2. Appearance: Due to their richness in organic matter, Histosols are darker, while the lower organic matter content in aridosols gives them a lighter hue.
3. Water retention: Histosols can retain water more effectively than aridosols.
4. Decomposition speed: Histosols also show a higher rate of decomposition compared to aridosols.
Answer:
a. Anabolic pathways synthesize molecules, necessitate energy, and are endergonic.
Explanation:
Anabolic pathway refers to the metabolic processes that synthesize intricate molecules from simpler ones, generally through condensation (where monomers are linked covalently, generating water as a by-product). It demands energy for forming new bonds, which indicates that it is endergonic.
Conversely, the catabolic pathway pertains to metabolic reactions that dismantle complex moleculesinto simpler components, typically through hydrolysis (where water is utilized to sever bonds within the polymer). It liberates energy during the bond-breaking process, this indicates it is exergonic.
Based on this information we can ascertain that the correct answer is a. Anabolic pathways synthesize molecules, necessitate energy, and are endergonic.

The AraC protein associated with the ara operator functions as a repressor to prevent transcription of the ara operon. In the presence of arabinose, the AraC protein acts as an activator; however, in its absence, it serves as a repressor. When arabinose is not available, AraC remains as a
homodimer. One AraC molecule attaches to the ara initiator while another binds to a distinct regulatory region in the DNA known as the ara operator.
At any given time, one (1) billion tons of phytoplankton can be found. Every year, around 45 billion tons of phytoplankton exist in the ocean. Beyond serving as a food source for fish, they play a vital role in the carbon cycle. This phytoplankton absorbs 45–50 billion tons of inorganic carbon into their cells, representing the principal source of atmospheric oxygen.
Answer: This indicates that the allele for green pods is dominant over that for yellow pods.
Explanation: Dominant traits will manifest even in the presence of the alleles for other traits. If every offspring shows green pods despite carrying the allele for yellow pods, it confirms that green is the dominant trait.
