Two decades ago, while researching her doctoral thesis, ecologist Suzanne Simard discovered that trees communicate their needs and send each other nutrients via a network of latticed fungi buried in the soil — in other words, she found, they “talk” to each other.
Answer:
Mitochondrial DNA is circular, so it doesn't shorten when it replicates unlike the rest.
Nuclear DNA is present in the nucleus of eukaryotic cells. When working with the DNA samples, the best source of nuclear DNA is hair root that anchors the whole shaft of hair. Hair root possesses cells that are called as keratinocytes.
Answer:
The main difference between sieve tubes and companion cells is that sieve tubes are the long, narrow, pointed tubes present in the phloem of angiosperms whereas companion cells are attached to the sieve tubes, regulating the activity of sieve tubes.
Answer:
The correct answer is option C "The pressure change causes the organ of Corti to vibrate vertically".
Explanation:
The organ of Corti is an important structure for auditory perception that acts as a receptor organ for hearing. The organ of Corti is located in the mammalian cochlea and it allows for the transduction of auditory signals into nerve impulses according to the vibrations that are received from external sources. If the receiving sounds comes from the stapes pushing against membrane covering the oval window, the pressure change will causes the organ of Corti to vibrate vertically. Stimulus from membrane covering the oval window are sent to the organ of Corti, which responds by vibrating vertically.
