bones attach to bones by

bones are to produce movement when contract.
done

muscle
joint
cartilage

Explanation:

1. For the first blank: The point where two bones connect is called a joint. So we choose "joint".
2. For the second blank: Bones attach to other bones by ligaments (though the options here have "cartilage" is not correct for bone - to - bone attachment, but among the given options, the correct term related to bone - bone connection structure in the options? Wait, maybe there is a typo, but if we consider the options, the first blank is joint. Wait, maybe the second blank: Wait, the options given are muscle, joint, cartilage. Wait, actually, bones attach to bones by ligaments, but if the options are muscle, joint, cartilage, maybe there is a mistake. But for the first statement: "The point of connection between two bones is a joint" is correct. For the second, maybe the intended is that bones attach to bones by (maybe the options are wrong, but if we go with the given options, maybe the second blank: Wait, no, maybe the third blank: "Bones are moved to produce movement when muscles contract". Wait, let's re - examine:

First statement: "The point of connection between two bones is a joint" – correct.

Second statement: "Bones attach to bones by..." – actually, ligaments attach bones to bones, but if the options are muscle, joint, cartilage, maybe there is an error. But if we assume that maybe the options are misprinted, and for the third statement: "Bones are moved to produce movement when muscles contract".

Wait, the first drop - down (the one with the visible options: muscle, joint, cartilage) is for the first blank. So:

1. First blank: joint (because the point of connection between two bones is a joint).

1. Second blank: Let's assume that maybe the options for the second blank (the middle one) are different, but if we consider the context, bones attach to bones by ligaments, but if the options are not there, maybe the second blank is "cartilage" is wrong, muscle is for bone - muscle, joint is for bone - bone connection. Wait, maybe the second blank is supposed to be "ligaments" but it's not in the options. But given the options in the first drop - down (muscle, joint, cartilage), for the first blank: joint.

1. Third blank: "Bones are moved to produce movement when muscles contract", so the third blank is "moved" and the agent is muscles.

But based on the given options in the first drop - down (the one shown: muscle, joint, cartilage) for the first blank:

First statement: "The point of connection between two bones is a joint" – so first blank: joint.

Second statement: "Bones attach to bones by..." – if we have to choose from muscle, joint, cartilage, maybe it's a mistake, but maybe the second blank is "cartilage" is wrong, muscle is for bone - muscle, so maybe the second blank is supposed to be "ligaments" but it's not there. Alternatively, maybe the second blank is "muscle" is wrong, joint is for connection.

Wait, perhaps the intended answers are:

1. The point of connection between two bones is a joint.

1. Bones attach to bones by (maybe the options are wrong, but if we go with the given options, maybe it's a mistake, but let's proceed with the context).

1. Bones are moved to produce movement when muscles contract.

So for the first blank (the one with the visible options: muscle, joint, cartilage), the answer is joint.

Answer:

1. The point of connection between two bones is a joint.
2. (Assuming the second blank has options like ligaments, but if we have to use the given options in the first drop - down, maybe it's a misprint. However, based on the first drop - down options for the first blank: joint)
3. Bones are moved to produce movement when muscles contract.

(Note: There might be errors in the provided options, but based on the anatomical knowledge, the first blank should be joint, and the third blank is related to muscles causing movement of bones.)
