1. <span>tRNA is the one carrying amino acids
2. </span>Mutation does not always affect the evolution of a species because <span>not all mutations affect an entire species.
3. </span><span>The type of chromosomal mutation that occurs here is an example of a deletion mutation. Specific genetic data, or DNA is removed and the remaining portions of chromosomal information have rejoined.
4. </span><span>A chromosomal deletion mutation
5. </span>The mutagens that result in cancer damage DNA by (b) weakening the DNA strand or interfering with base pairing. This mutagens are called carcinogens, if they cause a damage to a gene that makes a DNA repair protein, it means that a cell will have less ability to repair itself, and ,as a result, this will lead to formation of cancer.
The selective breeding helps to maintain pure breed and hence exclude the hybrids.
<h3><u>Explanation:</u></h3>
Selective breeding is a very commonly practiced procedure in plant management and animal husbandry. This selective breeding helps to achieve and maintain the homozygous traits of selective characters. For example, if two dogs with white colour are breed, then their progenies will be white too. Thus the selective character i.e fur color will be maintained.
In crops, if the plants with desired fruit characteristics are bred with each other then superior quality of fruits are achieved and maintained over generations. This is very essential economically too.
The right answer is A) DNA.
During evolution, the mitochondria have retained their own genome, which, although very small compared to that of a bacterium, is essential for the proper functioning of these organelles. Confined within the mitochondria, organelles that produce cellular energy, the mitochondrial genome (mtDNA) is distinct from the DNA in the nucleus. The transmission of this DNA is generally called non-Mendelian because it is only transmitted by the mother.
Chloroplasts contain DNA grouped into nucleoids; each chloroplast can contain up to 100 copies of the genome. The DNA molecules of the chloroplast genome are generally linear or branched. The chloroplast genome is very small, 37 to 220 kb and usually contains about a hundred genes
Answer: The correct answer to the question is DILATED PUPILS.
DILATED PUPILS is not a sign of sepsis.
Explanation: Sepsis can be defined as the way our body system respond to infection or invasion of a foreign body into the body system.(usually bacterial infection)
When Sepsis becomes severe,it is injurious to organs of the body(affects their function in a negative way).
Sepsis occurs when the body's immune system tends to fight infection in the body by the release of certain chemicals(cytokines and prostaglandins),the body instead of reacting in a coordinated manner to these chemicals rather reacts out of proportion to these chemicals released to fight infection and this will lead damage to organs of the body system.
Sepsis is characterised by Fever(above 101°F (38.3°C) or below 96.8°F (36°C), increased in respiratory rate (more than 20 breaths per minute), Increased heart rate (more than 90 beats per minute),increased white blood cell count,low blood pressure and mental confusion.
Treatment of Sepsis includes the administration of antibiotics and intravenous fluid, administration of drugs to support blood pressure and administration of steroids.
