List the steps of how a squirrel hibernates.
hoa [83]

Answer:

1. First of all, a squirrel would make sure to stash lots of food before and during the winter.

2. The squirrel would claim its own tree hollow/burrow.

3. They wrap themselves into a tight ball and go into a state of torpor (Torpor is a state where their body temperature becomes about the same temperature as their surrounding hibernaculum. This causes their heart rate to slow and causes them to use less energy)

4. Squirrels get up after 20 or so days to rewarm themselves up, and perhaps eat something to regain their energy. After that they will head back to their hibernaculum to continue hibernation.

5. When spring approaches they will fully wake up, go eat, regain their energy, and prepare themselves for the mating season.

Hope this helps :)

Under physiological conditions, peptide bond formation and degradation both require enzymes, but only formation requires couplin
posledela

Answer:

thermodynamically unstable but kinetically stable.

Explanation:

The complete question is as follows:

Under physiological conditions, peptide bond formation and degradation both require enzymes, but only formation requires coupling to GTP hydrolysis. Based on this information, peptide bonds under physiological conditions are:

A. both thermodynamically and kinetically stable.

B.thermodynamically unstable but kinetically stable.

C.thermodynamically stable but kinetically unstable.

D. both thermodynamically and kinetically unstable.

  • The term thermodynamically unstable refers to the fact that the peptide bonds are prone to breakage under physiological conditions.
  • The reason why one can conclude the thermodynamic instability of the peptide bonds under physiological condition is that there is a need for a source of energy i.e. GTP hydrolysis for the formation of the peptide bond.
  • The fact that the breakage of peptide does not require any input of energy but the only formation does confirms the fact that under physiological conditions they are thermodynamically unstable.
  • Even though they are thermodynamically unstable, they are kinetically stable because both the formation and degradation require enzymes.
  • The function of enzymes is to decrease the activation energy and hence, increase the rate of reaction. This means that if the enzymes are absent the rate of breakage of peptide bonds would be really slow this points out to the fact that they are kinetically stable under physiological conditions.

Hello,

Question:

Over time bacteria get used to anti bacterial medicine. Doing this can add symptoms and take away the easiest process of healing grout the human and destroying the bacteria.

Using complete sentences, explain how this speeds up the process of evolution in bacteria.

Answer:

Well, the reason medicine speeds up the evolution of bacteria because it needs to put the medicine ineffect for the vaccine to work properly. The faster it works the easier and less painful it will be for that person. Thats why when they go to hospitals they try to give treatment as fast and quickly as possible so there is no further damage. The medicine works almost instantly.

Edited Answer:

The reason bacteria can evolve faster because the DNA which is sharing which the evolution happen much faster, mostly because you don't have to rely on mutations.
