Answer:
Pulmonary circulation moves blood between the heart and the lungs. It transports deoxygenated blood to the lungs to absorb oxygen and release carbon dioxide. The oxygenated blood then flows back to the heart. Systemic circulation moves blood between the heart and the rest of the body.
Explanation:
Answer:
It is a learned behavior.
Explanation:
Typically, tool use implies a complex behavior that requires training and observing someone else who already has that particular ability. Thus, this ability shall be learned by one generation from the previous one, which shows and teaches this behavior to the next one.
Answer:
piwi-interacting RNAs (piwi-RNAs)
Explanation:
The piwi-interacting RNAs (piRNAs) are small non-coding RNAs (from 21 to 31 nucleotides) that are abundantly expressed in the animal germline in order to control the expression of target sequences. The piRNAs associate with PIWI proteins from the Argonaute family (AGO) to form an effector complex that binds to complementary target DNA/RNA sequences. These small ncRNAs target Transposable Element (TE) transcripts to suppress TE expression and thus maintain genome integrity. The piRNAs can also guide epigenetic remodeling complexes that suppress gene expression by methylation of target DNA sequences in the nucleus.
The option that describes a benefit of sustainable agriculture is ; ( D ) soil erosion is reduced
<h3>What is soil erosion </h3>
Soil erosion is the gradual removal of soil particles which leads to the washing away of soil nutrients. soil erosion is caused by the negative impact of floods ( water and wind ).
The reduction in soil erosion is a benefit of sustainable agriculture. While The depletion of aquifers and the overgrazing of farmland are not benefits of sustainable agriculture.
Hence we can conclude that a benefit of sustainable agriculture is soil erosion is reduced.

You boil the salt water because salt has a higher boiling point than water and therefore the water will evaporate, not the salt
