Answer:
Polyploidy
Explanation:
Polyploidy can be defined as a rapid method of speciation that has been important in the history of flowering plants.
In plants, it involves the possession of two complete sets of chromosomes and it leads to the origin of new species.
Hence, the two sets of chromosomes comprises of triploidy (69 chromosomes) and tetraploidy (92 chromosomes).
Explanation:
Burning fossil fuels, releasing chemicals into the atmosphere, reducing the amount of forest cover, and the rapid expansion of farming, development, and industrial activities are releasing carbon dioxide into the atmosphere and changing the balance of the climate system.
Answer: we can make observations directly by seeing, feeling, hearing, and smelling, but we can also extend and refine our basic senses with tools: thermometers, microscopes, telescopes, radar, radiation sensors, X-ray crystallography, mass spectroscopy, etc. And these tools do a better job of observing than we can!
Protein recommendations are the daily dietary protein requirements for an individual based on that individual's weight.
<h3>What was the dietary protein requirement?</h3>
For a typical sedentary adult, the suggested dietary allowance is 0.8 grams per kilogram of body weight. For instance, 60 grams of protein should be consumed daily by a person who weighs 165 pounds, or 75 kilograms.
Christine has already ingested half of the 40 grams of dietary protein that her doctor recommended. This indicated that she had already ingested roughly 20 grams of the recommended dietary protein and needed an extra source of protein to meet her daily needs. Christie must therefore have four more servings of snacks to complete her daily protein requirements.
