Explanation:
Terrestial Animals - Animals which can only live on Land.Examples:- BEAR- CAT- DOG- DEER
Aquatic Animals - Animals which can only live on Water.
Examples:- FISH- OCTOPUSES- LOBSTERS- SEAHORSE
Amphibians - Animals which can live both on land and on water.
Examples:- FROGS- TOADS- SALAMANDERS
Arboreal Animals - Animals which live primarily on trees.Examples:- SQUIRREL- RODENTS- CHAMELEON
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.
Salt is the Inorganic matter.
Option D.
<h3><u>Explanation:</u></h3>
Organic matters are defined as those compounds of carbon expect the carbonates, bicarbonates, cyanides etc. These compounds were primarily thought to be produced only from the living organisms and were unable to be produced in laboratory. But later they were being produced in laboratory too.
Inorganic compounds are all the compounds except the organic ones.
Here, in the question, we see the compounds -
Protein - it's the polymer of amino acids which contain carbon, and isn't carbonates or bicarbonates, cyanides etc.
Carbohydrates and sugars are also similar to proteins which contain carbon and isn't the exceptions. So they are also the organic compounds.
But salt, commonly table salt is sodium chloride which doesn't contain carbon, so is Inorganic.
SI is a base 10 standardized system. I hope this helped and if not I highly recremend talking to your teacher or a parent.
Answer:
open cluster
Explanation:
As the name suggests, an open cluster is a star cluster that is loose and disorganized.
