The answer is D, because carbon footprint is defined by the amount of carbon dioxide released into the air by human activities.
A benefit of genetic engineering is the production of valuable proteins that have helped in managing of illness in human beings. Bacteria were genetically engineered to produce proteins of medical importance. One example of such a protein is human insulin which is given the name humulin and is made using E. coli bacteria.Earlier, insulin from pig cells was used to treat patients with diabetes but many of them could not tolerate it because it has a slightly different arrangement of amino acids from that of humans and so the human body rejects it. Humulin is tolerated by the human body and so many patients are now using it to lead normal lives.
The answer is True
The calorie that you get from drinking vitamin water mostly comes from sugar/carbohydrate. The sugar content of vitamin water is high enough to become close with a soft drink. The calorie content would be around 6 calories per ounce.
The transpiration pull is just one of the mechanisms that explain the movement or translocation of water in plants, particularly water ascent in tall trees. There is no single exacting explanation as yet for the ascent of water but several theories have been proposed. Of these, the one which has gained wide support is the cohesion-tension theory which recognizes the crucial role of<span> transpiration pull</span><span> as a driving force. These theories are briefly described below.. I dont know maybe this might be helpful</span>
Answer:
Subtraction of the number of protons from the mass number.
Explanation:
The number of protons in the nucleus of the atom is equal to the atomic number (Z). The number of electrons in a neutral atom is similar to the number of protons. The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus.
To determine the number of neutrons in an atom, we only have to subtract the number of protons from the mass number. Take note that the nucleus of an atom is composed of protons and neutrons. And the number of particles present in the nucleus is referred to as mass number (Also called atomic mass).
