Answer:B.) Global warming causes air to be moister, resulting in more frequent blizzards.
Explanation:
Answer:
What this statement means is that experimentation is not enough, but that true knowledge comes from the analysis of results in a critical and meticulous way
Explanation:
Scientific knowledge is based on the scientific method and the results of the research, however that information is useless if it is not interpreted.
When the results are analyzed by scientists who support the same theories and have the same opinions, the results are not enriched as much as when exposed to different points of view. The debate tests the hypothesis giving rise to more complete answers.
Answer:
Constitutive activation is the alteration of a protein or signaling pathway such that it is functional or engaged even in the absence of an upstream activating event. For example, RasD is constitutively active because it cannot bind GAP and therefore remains in the GTP-bound, active state even when cells are not stimulated by growth factor to activate a receptor tyrosine kinase.
Constitutively active Ras is cancer promoting because cells will proliferate in the absence of growth factors, and thus normal regulatory mechanisms for cell proliferation are bypassed.
(a) A mutation that resulted in Smad3 binding Smad4, entering the nucleus, and activating transcription independent of phosphorylation by the TGFβ receptor would render Smad3 constitutively active.
(b) A mutation that made MAPK active as a kinase and able to enter the nucleus without being phosphorylated by MEK would render MAPK constitutively active.
(c) A mutation that prevented NF-KB from binding to IK-B or that allowed NF-KB to enter the nucleus and regulate transcription even when bound to IK-B would render NF-KB constitutively active.
Answer:
comparative anatomy:
compares the genomes of different organisms
compares the limbs of different organisms
molecular biology:
compares fossilized structures to living organisms
compares cells of organisms
EXPLANATION:
Comparative anatomy is the study of similarities and differences in the anatomy of different species.
Molecular Biology is the field of biology that studies the composition, structure and interactions of cellular molecules – such as nucleic acids and proteins – that carry out the biological processes essential for the cell's functions and maintenance.

<span>While Acid fast bacteria retain carbol fuchsin after acid-alcohol treatment, non- Acid fast bacteria are decolorized by acid-alcohol.
Bacteria of genus mycobacterium are best stained using acid-fast method. A mixture of Phenol and fuchsin is carbol fuchsin. In acid-slcohol, acid is hydrochloric acid.</span>
