Ketones are produced when body fat is burned for the production of energy. Normally, ketones should be present in very low amounts, the sample. If Marissa had to lose weight, then she must be following a ketogenic diet, which means less carbs in the diet and more fat and proteins, so that fat-burning state is achieved in the body. This diet also suppresses hunger. It is apparent that the nurse observed fewer ketones in the sample of Marissa, and got to know that she had been eating carbs and hence, was cheating on her diet.
Answer:
Empirical evidence of his ideas
Explanation:
The scientific process involves the formulation of hypotheses that enable to answer questions about the real world, and then to carry out experiments or observations that are used to confirm (or reject) such predictions. In the last 160 years, Darwin's ideas on 'descent with modification' have constantly been subjected to experimental assessment, and obtained data confirmed his observations. For example, molecular evidence based on the DNA and RNA -which constitute the genetic material of all living organisms- has shown the conservation of this process. In consequence, molecular evidence has been used to construct 'evolutionary' phylogenetic trees from DNA/RNA sequences. Moreover, evidence in genetics has shown the critical role played by mutations in the mechanism of natural selection proposed by Darwin, thus also confirming his theories. These are only some examples, and supporting evidence confirming Darwin's ideas has been collected from different research fields ranging from ecology to molecular biology.
Correct answer: A). Trees would grow faster
The insect resistant plants are genetically modified in such a way that they contain some toxic substance for the insects. when the insect tries to infect such plant the toxic substance is released from the plants and it will kill the insect and the plant stay away from healthy and give high productivity to farmers.
Example: Bt crops
Hence, the correct answer would be option A.
Answer: Chloroplasts, the organelles responsible for photosynthesis, are in many respects similar to mitochondria
Answer:
As climate warms, CO2 increases because plants remove less of it.
Explanation:
Don't really have an explanation.
