if anyone could help me with these questions. would be much appreciated.

I'd be happy to help you with these questions! Let's go through them one by one and explain how to arrive at the correct answers.

1. A eukaryotic cell in a human body has just reproduced asexually. Which of the following has most likely just occurred?
To determine the answer, we need to understand the process of asexual reproduction in eukaryotes. Asexual reproduction involves the production of genetically identical offspring from a single parent, without the involvement of gametes (sex cells) or fertilization. The process that best fits this description is mitosis, which is the division of a cell to produce two genetically identical daughter cells. Therefore, the correct answer is C. Mitosis.

2. In which phase of the cell cycle are the chromosomes split?
To determine the phase in which chromosomes split during the cell cycle, we need to recall the different stages of cell division. The correct answer is when the chromosomes split is in the phase called anaphase. In anaphase, the sister chromatids (replicated chromosomes) separate and move to opposite poles of the cell. Therefore, the correct answer is A. Anaphase.

3. While being examined, a patient is found to have problems moving the thumb. Which type of joint is being affected?
To identify the type of joint being affected, we need to understand the different types of joints in the human body. The thumb is primarily associated with a joint called the carpometacarpal (CMC) joint, which connects the thumb to the hand. The CMC joint is a saddle joint, as its shape allows for the thumb's unique range of movement and opposition to the other fingers. Therefore, the correct answer is B. Saddle.

I hope this helps! Let me know if you have any other questions.
