The answer to the question presented above would be 'require frequent rainfall'. A plant native to the chaparral would be expected to require frequent rainfall. This is because it cannot survive in dry lands and without constant water.
Cephalopoda
Explanation:
Cephalopods are commonly known as inkfishes.
But cephalopods are not at all fishes. They are molluscs.
They belong to Class Cephalopoda of phylum Mollusca.
Like other molluscs, these are also soft bodied, but have a series of tentacles that actually developed from theprimitive foot.
Cephalopods have a well developed nervous system and have large bulging eyes.
Examples of cephalopods are, octopus, giant squid etc.
Considering all the above characteristics, we can conclude that the predator stated in the question is most likely to belong to the clade cephalopoda.
It’s the release of harmful gases e.g. carbon dioxide into the environment due to human activity, therefore causing a rise in global temperatures, which is climate change. Warmer temperatures negatively impact our environment because it causes a decrease in biodiversity, allows more diseases to spread(most live in warmer temp.) and so on.
Answer:
The hydrogen bonds between water molecules
Explanation:
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.
