Correct Answer: B. exfoliation

Correct Answer: C) athlete must have carried out anaerobic respiration during the race

Explanation

The question is asking why an athlete's muscle cell fluid contained a high concentration of lactic acid after a 100m race. Lactic acid is produced during anaerobic respiration when there is not enough oxygen to produce energy. This means that the correct option is C, which states that the athlete must have carried out anaerobic respiration during the race. During exercise, the body needs more energy to fuel the muscles. If there is not enough oxygen being supplied to the muscles to produce this energy aerobically, anaerobic respiration takes place. This process produces lactic acid as a waste product, which builds up in the muscles and can cause fatigue and pain. Therefore, the athlete's muscle cell fluid contained a high concentration of lactic acid because they carried out anaerobic respiration during the race, which is a common occurrence during intense exercise. Options A, B, and D are incorrect as they do not relate to the production of lactic acid during exercise. It is important for athletes to train and prepare their bodies for intense exercise to prevent the build-up of lactic acid and reduce the risk of fatigue and injury. This can be achieved through regular exercise and a healthy diet.

Correct Answer: C. potassium

Correct Answer: A. reducing average cost as production increases

Explanation

As long as the Long run average cost curve is declining, then internal economies of scale are being exploited. If LRAC is falling when output is increasing, then the firm is experiencing economies of scale.

Correct Answer: A) The demand for a king in Israel

Explanation

The question is asking why Samuel's lack of parental responsibility had a particular consequence in the Bible. The options suggest four possible outcomes. Option A is the correct answer, which says that Samuel's lack of parental responsibility led to the demand for a king in Israel. This means that because Samuel did not adequately raise his sons to be good leaders, the people of Israel no longer trusted them to lead the nation. As a result, they demanded a king to rule over them instead of having judges like Samuel.

It is important to note that this demand for a king was not necessarily a positive thing. In fact, it was seen as a rejection of God's leadership over Israel. The people of Israel were supposed to trust in God to guide them and provide for them, but they wanted a human king instead. This ultimately led to many problems for Israel in the future.

Option B suggests that Samuel's lack of parental responsibility led to his untimely death at Ramah. This is not correct because there is no indication in the Bible that Samuel's parenting had anything to do with his death.

Option C suggests that Samuel's lack of parental responsibility led to the defeat of the Israelites in battle. While it is true that the Israelites experienced defeats in battle during the time of the judges, there is no direct connection between Samuel's parenting and military success or failure.

Option D suggests that Samuel's lack of parental responsibility led to the anointing of David as king. While Samuel did anoint David as king, this was not a direct consequence of his parenting. Rather, it was a result of God's plan for Israel's leadership.

In summary, Samuel's lack of parental responsibility led to the demand for a human king in Israel, which was seen as a rejection of God's leadership. This was not a positive outcome and had negative consequences for Israel in the future.
