Answer:
Most of our electricity comes from coal, nuclear, and other non-renewable power plants. Producing energy from these resources takes a severe toll on our environment, polluting our air, land, and water. Renewable energy sources can be used to produce electricity with fewer environmental impacts.
Explanation:
There are many ways in which they are different but one of the important one is :
in photosynthesis, CO2 is used and O2 is released while in cellular respiration O2 is taken and CO2 is released !
Add my enzyme, add more substrate and adjust pH to optimal level will all increase the rate of a reaction. Freezing or too low of temperatures will make most enzymes unable to work.
The first three are correct.
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.
