I think impact accretion provides thermal energy to the differentiation of different layers in a planetiesimal. Accretion is the process through which planets form as material orbiting some stars gathers together through collisions and gravitational or electrostatic attraction, eventually forming larger and larger bodies. Planetesimals are objects that forms through accretion during the early stages of planet formation. They may combine with one another to form protoplanets and eventually planets.

How can reverse transcriptase inhibitors slow the replication of dna? give an example that lay persons without this knowledge co
almond37 [142]

Preventing reverse transcriptase activity is a tactic in the fight against contagious infections like HIV. Drugs can be created that specifically target and inhibit the reverse transcriptase enzyme, essentially freeing your DNA polymerase to carry out its function.

<h3>What are reverse transcriptase?</h3>

AZT and DDI are two of the more well-known medications among them. AZT stands for azidothymidine in the acronym. This medication traps the invasive reverse transcriptases and causes them to stop copying RNA into DNA. When that occurs, the HIV virus is unable to multiply, and your immune system can more readily get rid of these infections from your body. Because it is so specialized in combating reverse transcriptase, AZT has been referred to as a magic bullet.

The fact that your body periodically uses reverse transcriptase-like processes for normal functioning makes it far from perfect, and the fact that HIV can swiftly adapt so that it is no longer deceived by AZT make it less than ideal. Because of this, a combination of many reverse transcriptase inhibitors, such as AZT and DDI, is frequently required for an effective HIV treatment.

Why cycus are called conifer? give its 3major characteristics features​
Licemer1 [7]

Answer:

Cycads /ˈsaɪkædz/ are seed plants that typically have a stout and woody (ligneous) trunk with a crown of large, hard, stiff, evergreen and (usually) pinnate leaves. The species are dioecious, therefore the individual plants of a species are either male or female. Cycads vary in size from having trunks only a few centimeters to several meters tall. They typically grow very slowly[3] and live very long, with some specimens known to be as much as 1,000 years old.[citation needed] Because of their superficial resemblance, they are sometimes mistaken for palms or ferns, but they are not closely related to either group.

Cycads are gymnosperms (naked seeded), meaning their unfertilized seeds are open to the air to be directly fertilized by pollination, as contrasted with angiosperms, which have enclosed seeds with more complex fertilization arrangements. Cycads have very specialized pollinators, usually a specific species of beetle. Both male and female cycads bear cones (strobili), somewhat similar to conifer cones.

Cycads have been reported to fix nitrogen in association with various cyanobacteria living in the roots (the "coralloid" roots).[4] These photosynthetic bacteria produce a neurotoxin called BMAA that is found in the seeds of cycads. This neurotoxin may enter a human food chain as the cycad seeds may be eaten directly as a source of flour by humans or by wild or feral animals such as bats, and humans may eat these animals. It is hypothesized that this is a source of some neurological diseases in humans.[5][6]

Cycads all over the world are in decline, with four species on the brink of extinction and seven species having fewer than 100 plants left in the wild.[7] The plant has a very long fossil history, with evidence that they existed in greater abundance and in greater diversity before the Jurassic and late Triassic mass extinction events.
