<span>The resulting movement is scapular protraction and rotation.The scapula is moved along the chest wall. The muscles involved in this process are the serratus anterior, which is the prime mover. Pectoralis minor and major, the latter acting through the humerus, may assist (act as synergists).</span>
C is the awnser….i’m just guessing bro but c seems good
Answer:
d
Explanation:
Fishes are aquatic vertebrates having scales, pharyngeal gill slits and paired fins. ... Most fish are ectothermic ("cold-blooded"), allowing their body temperatures to vary as ambient temperatures change. fishes have scales that covers the skin of fishes. Thus, the correct answer is option D.
Answer:
It is due to the proofreading activity of RNA polymerase.
Explanation:
RNA polymerase is the most significant enzyme of transcription process which deals with the synthesis of RNA from DNA.
RNA polymerase reads the template DNA or antisense strand of DNA and helps in the addition of correct nitrogen bases to the growing RNA strand that is complementary with respect to the nucleotides present within the template DNA strand.
After the addition of bases to the growing RNA strand the proofreading process take place in to verify that all the incorporated bases within the growing RNA chain is correct or not.If any incorrect base is incorporated in the growing RNA strand then the proofreading process replace that incorrect base with the correct one.
All this processes occur in very quick succession that"s why RNA polymerase can locate a promoter sequence faster than two molecules can collide.
Answer:
D
Explanation:
Sample D will undergo the fastest rate when subjected to chemical weathering.
What is weathering?
- It is the physical disintegration and chemical decomposition of rocks to form sediments and soils.
- Physical weathering is also known as mechanical weathering. It entails breaking rocks into smaller sized chunks.
- Chemical weathering is the decomposition of rocks by chemical action.
From the given choices, option D will have the largest surface area exposed to chemical actions. It has more surface area compared to the others. The more broken a mass is, the more its surface area is.
Reaction rates are affected by:
- Increase in surface area
- Increase in temperature
- Higher concentration
- Increase in pressure
The last cube has the highest surface area and will have the fastest rate of weathering.
