Answer:
genotype
Explanation:
Within an individual organism, the specific combination of alleles for a gene is known as the genotype of the organism, and (as mentioned above) the physical trait associated with that genotype is called the phenotype of the organism.
D is the best because the water pollution affects the environment
Answer:
C. After running 20 miles
Explanation:
Anaerobic respiration only occurs when an organism lacks all the oxygen we need to function. After running 20 miles, you will be out of breath, and you will have been using more energy than your respiratory system could produce alone. Due to this, your body will start using some of your energy stored within cells in order to continue functioning. This kind of respiration is basically 'burning calories'.
Answer: Poly(ethene) has a higher melting point than ethene. The reason can be seen in the explanation below.
Explanation:
Ethene is one of the most important alkene hydrocarbons which is one of the main products obtained during the cracking of the gas oil fraction of petroleum.
Polymerization is a process whereby two or more simple molecules are linked to form a much larger molecule usually called polymers. Poly( ethene) is formed when ethene and it's derivatives undergoes polymerization reaction. Therefore poly( ethene) is a polymer of ethene.
To describe the reason why there is higher melting point in poly (ethene) than ethene is that poly( ethene) consists of very long chain carbon atoms which are held together by a strong covalent bonds. There are greater intermolecular forces between the long chains compared with smaller simple molecules like ethene.
The answer is B because when you feel pain your nervous system is the first thing to react
