Answer:
E) A, C, and D
Explanation:
A nosocomial infection, often referred to as healthcare-associated infection (HAI), is an infection contracted in a hospital or other healthcare facility. Both people and animals are at risk of acquiring these illnesses while receiving treatment. This includes animals who are being seen for vaccinations, any animal that comes into the hospital, and patients undergoing very lengthy surgical procedures. It has nothing to do with animals being very young or very old.
This is why option E is the correct one.
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.
D. intensive irrigation i guess well i have the same question
Recombination
: the process occurring in Meiosis I, in which offspring are able to obtain unique traits resulting in an array of different phenotypes (physical appearances).
Prophase I,
the homologous chromosomes line up in the middle of the cell and exchange segments of alleles, and then lining up in the cell in a NON-uniform way.... therefore resulting in genetically unique offsprings rather than identitical.
Mutations are result of evolutionary factors. They create genetic diversity that helps species adjust to different climates, behaviours and foods. Mutations that occur in a fit indivual can result in offspring that are genetically more successful in adjustments to different climates, foods, and environments.
All in all Recombination results in unique looking indivuals, whereas mutations result in greater survival chances of a species.
Answer:
The correct answer is option D. "lipid".
Explanation:
Lipids, known also as fats or oils, are organic compounds that are insoluble in water and are made up of carbon, hydrogen, and oxygen. The formula of this question shows a biomolecule that is made up of this three atoms, and even though carbohydrate are made up of this three atoms as well, we can determine that it belongs to a lipid because it contains many more hydrogen atoms than oxygen atoms. Other characteristic of lipids is their long chains of carbon and hydrogen atoms, which are represented by the lines shown in blue. I attached the missing formula.
