What causes continental lithosphere to become thinner and weaken?

Answers

Answer 1

Answer: Continental litosphere is made of relatively light weight minerals. It has a low density. Oceanic litosphetre is composed of a heavier minerals. Tensions and heat flow in the asthenosphere( beneath the litosphere) waekens the floating solid plate causing it to break apart. Thinning of the continental litosphere is result of hydration weakening. It is a special consequence of plate tectonics. By hydration weakening the basal portions of litosphere can be transformed into convecting asthenosphere.

4. in the plant arabadopsis, the flc gene is a regulator of flowering. when expressed, flc is transcribed and translated into a transcription factor protein that functions to repress flowering. suppose a researcher introduced a small interfering rna (sirna) that was complementary to the flc mrna. what effect would this have on flowering in arabidopsis? explain (4 pts)

Answers

The introduction of a small interfering RNA (siRNA) complementary to the flc mRNA in Arabidopsis would likely result in the repression of the flc gene and promote flowering.

The siRNA would bind to the complementary flc mRNA, leading to its degradation through RNA interference (RNAi) or preventing its translation into the transcription factor protein that represses flowering. This would decrease the concentration of the FLC protein, releasing the repression of flowering genes, and leading to an increase in flowering in Arabidopsis.

siRNA technology can be used to target specific genes and regulate their expression in plants, animals, and other organisms. In this case, it can be used to manipulate the expression of the flc gene and promote flowering in Arabidopsis, providing a potential tool for crop improvement and genetic research.

C. he does not offer any possible reason for wanting to murder Fortunato

Answers

In Poe's "The Cask of Amontillado Amontillado" the reason that Montresor is an unreliable narrator is that he does not offer any possible reason for wanting to murder Fortunato. The correct answer is C.

the correct answer is that he makes exaggerated claims about fotunato

Wildfires are frequent In the Great Basin shrub steppe. Every time there is a fire outbreak, much of the natural vegetation is destroyed. What is the MOST LIKELY impact of fire on this ecosystem? A) A drastic reduction in the animal population due to migration or death by starvation. B) No impact, because the plants have only been temporarily removed from the ecosystem. C) There would be no rainfall because there are no trees or shrubs in the region. D) Non-native plants and animals would migrate into the region.

Answers

The correct answer is option A

The most likely effect of the fire outbreak is that due to fire most of the vegetation is destroyed and due to this most of the animal gets impacted and there is a drastic reduction in their number.

They will move due to another places in search of food which is known as migration else they will die there only because of the starvation.

The most likely answer is A) A drastic reduction in the animal population due to migration or death by starvation.
