Answer:
The liquid would be equivalent to Cytoplasm
The particles would be equivalent to orgnaelles
Explanation:
Cytoplasm is the liquid-like substance in the form of a gel that is also referred to as the protoplasm which is found outside the cell of living things. It is majorly mad up if dissolved molecules and water, as well as several cell organelles that carry out specific functions.
Comparing salad dressing to a cell, the liquid in the salad could be likened to the cytoplasm of a cell, while the particles in the salad could be likened to the organelles in a cell which performs various functions.
Answer:
Option A, most closely related to mammals
Explanation:
Insects like arthropods and molluscs have an open circulatory system and thus do have a distinguishable heart. Fish has two chambered heart. Reptiles have three chambered heart. Amphibians too have a three chambered heart.
All mammals and fish have four chambered heart. The right and left sides of the chambers have restricted entry and hence remain intact from each other
Hence, option A is correct
I am pretty for sure the answer is roots.
Answer:
A. The chromatin near cis-regulatory sequences will be more closed and there will be less transcription.
Explanation:
In the presence of histones, the cis-regulatory sequences of DNA like promoter, enhancers etc. are not exposed. The function of the histone acetyltransferases (HATS) is to cause chromosome decondensation i.e. removal of histones from the DNA so that transcription of the DNA could occur. Histone acetyltransferases (HATS) cause acetylation of lysine amino acid of the histone proteins. Acetyl group is negatively charged so the acetylation of histone proteins leads to the removal of their positive charge which ultimately leads to the decrease in the interaction between N terminal of histones and negatively charged phosphate group of the DNA molecule. As soon as histones are removed from the DNA where cis-regulatory sequences are located, the DNA becomes accessible for transcription.
But here a drug has been added which blocks the activity of histone acetyltransferases (HATS) in cancer cells. So it is quite evident that in these cells, histones will not get removed from the cis-regulatory sequences of DNA so the DNA will be more closer or tightly packed as a result of which less transcription will occur.
<span>Helium nuclei have a positive charge of 2+ when observed. Compared to a hydrogen nuclei, we can see that the Helium nuclei is more difficult to fuse as it has a greater charge than Hydrogen 1+. This chemical difference makes the answer true.</span>
