<u>Answer:</u>
In comparing stop-transfer and internal start-transfer sequences in proteins, it can be said that both are hydrophobic.
Option: (b)
<u>Explanation:</u>
- Hydrophobic means repelling water.
- Hydrophobic molecules are non polar i.e. that there is no static electric field produce by atoms of molecules.
- Due to this reason the hydrogen cannot form hydrogen bond with the molecules.
- Internal start- transfer process is a transfer process of peptide and moves through the side opening of translocon and the anchor itself in the 'membrane'.
- Stop-transfer sequences in proteins halts the 'process of translocation' and moves out through the 'side opening in translocation' to anchor.
The correct answer is - accident.
In general, the invasive species are introduced into a new environment accidentally.This means that they have not been introduced on purpose, or in order to cause any harm to the ecosystem, though there are some exceptions.
The invasive species are usually very dangerous to the local ecosystem. The reason for that is that they usually do not have predators in the new ecosystem, or if they are the predators, than the local flora and fauna do not have defense mechanisms to cope with it. They also act very aggressively, have more offspring, as well as having the offspring on much shorter periods of time, which ends in occupying the space of the local organisms and even leading to their extinction.
Answer:
The answer is C.
Explanation:
The term posterior teeth defines the teeth in the back of our mouths with their flat surfaces to crush the food. There are two kinds and they are called molars and premolars. The proximal contact of posterior teeth refers to these teeth being in contact with each other's surface areas constantly which result in erosion over time. The answer given in option C, decreased lenght of anatomic crowns is true because anatomic crown is the part of the teeth that is visible and covered with enamel so the constant contact affects this area and causes it to wear in time.
I hope this answer helps.
