Answer:
Tetraploid wheat evolved by allopolyploidization and subsequent diploid-like behavior due to cytological diploidization
Explanation:
Durum wheat (<em>Triticum durum</em>) or pasta wheat, is a tetraploid wheat species that has 28 chromosomes, i.e., seven pairs in each genome (2n = 4x = 28). Durum wheat was domesticated from wild emmer wheat, which originated by hybridization of two diploid wheat species with 14 chromosomes: <em>Triticum monococcum</em> (genome AA) and one wild progenitor (genome BB). <em>Triticum durum </em>is a typical example of evolution by hybridization and polyploidization, where the resultant tetraploid species has two complete sets of chromosomes. Allopolyploidization is one of the most common types of plant speciation. During meiosis, 28 chromosomes form 14 homologous chromosome pairs, because homologous chromosomes have developed 'restriction of pairing' (i.e., cytological diploidization). The restriction of pairing to fully homologous chromosomes ensures a correct meiotic behavior, which otherwise would be altered due to the high level of homology that still exists among chromosomes from different wheat progenitors.
Other things veterinarians are looking at is the boundary between animals, people, and the environment. Veterinarians need to work with human doctors to work on food safety, problems connected to cancer, etc. Veterinarians and human doctors can get facts from each other. The problems we face in society means that they have to cooperate with both the animal health side, the human health side, and environment side as well. One way they think of “one health” is evolving viruses. They are looking at this to find a solution by the use of comparative medicine and observing the environment.
Answer;
-Reduce the chance of errors in correspondence
-Easier to use for converting between units while measuring
-Make communication easier between scientists comparing data
Explanation;
-The metric system is a system that is based on joining one of a series of prefixes, including kilo-, hecto-, deka-, deci-, centi-, and milli-, with a base unit of measurement, such as meter, liter, or gram.
-Since the metric system is a decimal system of weights and measures it is easy to convert between units simply by multiplying or dividing by 10, 100, 1000, etc.
-It is an alternative system of measurement used in most countries, as well as in the United States.
Answer:
In explanation.
Explanation:
What is a punnett square used for?
It is a way to store data and keep track of things. It helps to predict the variations and probabilities that can come from cross breeding.
What do the probabilities of the possible offspring all add up to?
All can have 100%, 75%, 50%, or 25% depending on the specific trait.
Uranium is not a renewable resource.
Hope this Helps!!!
