Answer:
The bowl of ice cream contains ice cream with temperature below freezing point. A hot body contains more thermal energy than a cold body. Thermal energy only flows from a hot body to a cold body, and not the reverse.
The bowl of ice cream contain less thermal energy than it sorrounding envoirment (air and the kitchen counter), this creates a temperature gradient that forces thermal energy from the sorrounding envoirment into the bowl of ice cream because, according to thermodynamics, all bodies always tend to be in thermal equilibrium with its sorrounding. The thermal energy flows into the bowl of ice cream until it has the same thermal energy with its sorrounding; bringing the thermal gradient between them to zero.
The correct answer is:
Hydrostatic pressure will drop as blood moves away from the arteriole end of the capillary bed
Explanation:
The hydrostatic pressure is exerted by a fluid in a specific point as a consequence of the weight of this fluid. Since blood is a fluid, it presents a hydrostatic pressure. In consequence, the blood in the feet have more hydrostatic pressure than the blood in the heart
Answer:
Predicting future events in a person's life based on the position of the moon
Explanation:
pseudoscience is science that is fake, its predictions, no scientific basement
So, out of all of them, the last option is the only one that doesn't make sense, so its the answer.
Answer: B) mRNA processing events that lead to different types of exons being spliced together
Explanation:
When DNA is transcribed into mRNA, a primary RNA or pre-mRNA transcript is obtained that includes introns and exons. For this pre-mRNA to give way to an mRNA it must undergo a maturation process of the mRNA, which
is basically to eliminate all introns primary transcript and then binding exons.
So RNA splicing is a post-transcriptional process of maturing RNA from which certain sequential fragments are removed. This process is very common in eukaryotes, and can occur in any type of RNA, although it is more common in mRNA.
Removal of introns and binding of exons in the mRNA occurs before leaving the nucleus. This process is known as splicing. <u>The alternative splicing of identical RNA transcripts into different cell types can produce different molecules of mature mRNA that are translated into different polypeptides.</u>
