Essential amino acids are amino acids that cannot be made by the body, and therefore must be obtained through eating cetain foods. (C)
Answer:
Carbon dioxide
Explanation:
The Lewis structure of carbon dioxide shows that the carbon in CO2 must make 2 sigma bonds and it has no lone pairs.
The bond angle from O = C = O is 180° because the geometry is a linear geometry.
The correct answer is (C) Genetically modified crops requires less pesticide.
The genetically modified crops are designed in such a way that it requires less amount of pesticide. These plants contain the gene resistant for pest. These plants are often called as Bt plants. Almost 40% of the maize crops used in United States are genetically modified crops. All these are pest resistant and require very small amount of pesticide to kill some of the pest.
The slow twitch muscle fibres have a higher count of mitochondria which means it can process quicker, it receives a energy, it receives a good blood supply since it has a high amount of capillaries, which means it has a good supply of oxygen, which helps to maintain the use of the aerobic energy system for longer, making type 1 fibres more effect for endurance, while the type 2 fast twitch have less mitochondria and rely more on glycolysis.
