Deoxyribonucleic acid (DNA) is the hereditary material that lies within the nucleus of all cells in humans and other living organisms. Most of the DNA is placed within the nucleus and is called nuclear DNA.
A chromosome is made up of two chromatids which are joined by the centromere. The chromatids separate from each other during mitosis to form two new chromosomes. The DNA making up a chromosome is dispersed as chromatin.
Under a microscope, chromatids look like little dots and chromosomes are lines.
The answer is 50%.
The-related number of thumps every moment of the heart when working at its greatest that is generally evaluated as 220 short one's age achieved 90 percent of his most extreme heart rate when tried on a treadmill.
It is prescribed that you practice inside 55 to 85 percent of your most extreme heart rate for no less than 20 to 30 minutes to get the best outcomes from oxygen consuming activity. The MHR (generally ascertained as 220 less your age) is the maximum furthest reaches of what your cardiovascular framework can deal with amid physical movement.
Answer:
All the above options are correct. Hence the most relevant answers for the questions are all the options mentioned above.
Explanation:
Common names are not preferred because they can vary according to the people living in the society, religion, culture and their own suitability. We can get various example where a animal is known by various names in different countries or region.
Providing scientific name that is accepted by all over the world is more convenient rather than common names which are given by the local people to the specific animal or bird. Scientific name remove all the confusion between the the people. common names can be kept according to their location culture species and their language
The DNA of cats and dogs is more similar to the DNA of cats and hamsters because of the difference in their order.
According to taxonomic hierarchical classification, organisms are classified into seven different levels: Kingdom - Phylum - Class - Order - Family - Genus - Species. The more common level of classification, the more chances of similarities in the DNA patterns.
Three of the above animals have evolved from a single class,i.e., Mammalia. This means that all of them are mammals. But as evolution took place further, they got divided into two different orders. Cats and dogs went with the order of Carnivora while hamsters went with the order of Rodentia.
The cats and dogs belong to the same order while the hamster belongs to a different order. This means that the cats and dogs, thus, share a more common ancestor. They are more likely to possess more similar patterns of DNA than the hamster. It is because of this difference that the two categories possess a large difference in their DNA.
