The characteristics that apply only to prokaryotes from the list given above would be as follows:
-These cells have DNA in a region called the nucleoid.
-Some of these cells have structures like flagella and microvilli.
-These cells have cell walls made of polypeptides and polysaccharides.
Hope this answers the question. Have a nice day.
Answer:
The (Receptive) segment includes both dendrites and the cell body, which are the regions of the neuron that receive stimuli to excite the neuron. Channels in this region are (Gated chemically) ; no significant numbers of (Voltage gated) channels are present.
• The (Initial) segment is composed of the axon hillock. This segment contains voltage-gated channels.
• The (Conductive) segment is equivalent to the length of the axon. It contains voltage-gated channels.
• The (Transmission) segment includes the synaptic knob and contains voltage-gated channels and (Pumps) .
Explanation:
These questions are related to the extraction of DNA using detergents and ethanol.
1. Consistency and texture- the extracted DNA is white, spongy and moist or slime in nature.
2. Salt is used during the extraction process as the DNA is negatively charged molecule and to neutralize the negative charge which will allow the formation of precipitate.
3. The DNA is soluble in aqueous solution as the DNA is a negatively charged molecule therefore the negative charge makes it a polar molecule and it can form the interactions in the aqueous solution.
4. RNA could be present in the aqueous solution along with the DNA as both are the nucleic acid.
5. The base-pairing rule was suggested by the Chargaff who proposed that Adenine binds thymine and guanine binds cytosine.
5. The binding of adenine to thymine involves two hydrogen bonds and between guanine to cytosine involves three hydrogen bonds.
That doesn’t make sense the answer is false
Answer: the fibula
<span>Due to its position, the fibula it's not meant to support much of the body weight, but about two percent.</span>
<span> The fibula extends past the lower end of the tibia, forming the lateral maleole providing stability to the ankle joint. It has a lot of ligaments and muscles attached to it.
