The correct answer is letter a, it is because in wet drop method, it does not need to add water after placing the specimen because adding water before placing the specimen in the glass slide is already enough and after placing the specimen, a cover slip is the last step in finishing the method. That is why Johnny is not correct in doing the procedure.
The answer would be "<span>Cyclins are proteins that regulate when and how often a cell divides". Cyclins belong to a family of proteins that control the progression of a cell through its respective cell cycle. This is initiated by activating cyclin-dependent kinase (CDK) enzymes which regulate </span>transcription of RNA and process mRNA during mitosis.
It is false. The transcription in eukaryotes is affected by regulatory proteins that sticks to certain DNA arrangements that are sometimes found thousands of pairs away from the promoter. The regulatory arrangements can be found downstream, upstream, or even inside the segment of the converted DNA. A few regulatory arrangements probably exist for a given gene. It is interesting that the transcriptional activators and repressors operates by sticking to DNA at far areas from the promoter. The folding of DNA enables the approximation of remote areas of the double helix to assist in the positioning of the activator protein, affixed to the enhancer, near the initiation system and the promoter.

You Asked ➤ The goal of basic science is:
↴ OUR CHOICES ↴
A: To increase our understanding of general principles.
B: To improve a specific situation.
C: To solve a particular problem.
D: To use technology to improve quality of life.
------------------------------------------------------------------------------------
Answer ➤ A: To increase our understanding of general principles.
Explanation: One of the major goals of basic science is understand what the key principals that make it up. We learn how it functions and understand what make science part of our world.
••• HUH? WHY IS IT NOT THE OTHER CHOICES? •••
⇢ <u>B and C:</u> While basic science does help improve situations and solve problems, that is not the main reason why it is studied.
⇢ <u>D:</u> Science has helped us use more technology, but those levels are more advanced than the general basics.
I hope this answer is helpful to you, but please let me know if you have any other questions regarding it.

Answer:
Muscle contraction occurs when the thin actin and thick myosin filaments slide past each other. It is generally assumed that this process is driven by cross-bridges which extend from the myosin filaments and cyclically interact with the actin filaments as ATP is hydrolysed.
