The wrinkles signify that the brain is compressed which makes it take up less space in your head which makes it more eficent I guess.
Answer:
B. Release energy from bonds
Vucueil and Plast (including chloroplasts) and cell wall.
Explanation:
Objective lenses are responsible for the primary image formation in microscopes, they are the closest part to the object, it defines the image's quality and they determine the magnification and resolution. In an optical microscope you can usually find 3 or 4 objectives (4x, 10x, 40x and 100x) but other configurations and magnifications are possible, in the image I added you can see that.
<em>To determine which objective you will use you need to consider your specimen's size and what are the smallest features in it, NA (numerical aperture) must be considered as well, this is the ability to gather light and it determines depth of focus (how much you can focus without change in the image's sharpness), brightness and resolution (smallest distance between two objects). You'll also need to identify your observation method (phase contrast, darkfield, fluorescence, etc) and in what medium is your sample.</em>
I hope you find this information useful and interesting! Good luck!
Answer:
In vitro mutagenesis:
Another way of applying cloned DNA is in vitro mutagenesis. Here, a mutation is caused in a fraction of cloned DNA which is then transferred to the cell or organism, in order to determine the results of the mutation.
Disable cloned gene, when it's inserted back in the organism, it can be used to study phenotype.
rna interference:
RNA interference (RNAi) uses RNA molecules to prevent gene expression or translation causing in
inactivation of the targeted mRNA molecules.
It gives Double-stranded RNA homologous to remote gene which will cause a disintegration of mRNAs out of the gene.
