Please see the attached file of red blood cell. Inside and outside the concentration is same in the isotonic solution. So , blood celll do not shrink and swell when we placed in isotonic solution.
It’s true bc of something
Answer:
Explanation:
Deciduous and Coniferous trees are both Woody plants and can both be found in the forest, but there are significant differences between them including-
1) The leaves of deciduous trees change color and are shed seasonally while the needles of Coniferous trees are not lost seasonally, neither do they turn pale
2) Deciduous trees are flowering plants and so they bear their seeds in fruits while Coniferous trees are gymnosperms and so bear their seeds in cones.
3) Coniferous trees possess needles in lieu of leaves while deciduous trees possess broad leaves
4) Examples of Coniferous trees are firs, junipers, redwoods, spruces, and pines etc. while examples of deciduous trees are oak, maple, and elm etc.
Answer:
Explanation:
My best bet is DNA methylation at the site of Tweedledum's leptin gene or Histone Acetylation at the site of Tweedledee's gene.
B/c DNA methylation is a process by which methyl groups are added to the DNA molecule. Methylation can change the activity of a DNA segment without changing the sequence. When located in a gene promoter, DNA methylation typically acts to repress gene transcription. So this is probably repressing Tweedledum's leptin gene trancription which is not happening in Tweedledee.
Additionally, Histone Acetylation at site of Tweedledee's gene increases her trancription b/c Histone acetylation causes DNA to be more accessible and leads to more transcription factors being able to reach the DNA. Thus, acetylation of histones is known to increase the expression of genes through transcription activation.
I would say its between A and D, Hope it helps.
