<span>On a modern firearm, the feature that functions like the lock on a muzzleloader is the safety. The safety was added to modern guns to prevent them from accidentally firing, although it should be noted that a safety is a man-made mechanical device which makes it subject to failure at times.</span>
Explanation:
i didnt pay attention last year soooo sorry
Answer:
B. misalignment of the chromosomes during anaphase I
Explanation:
Aneuploidy refers to an error in the chromosomal number of a cell. This occurs when the chromosomes fail to separate equally into individual cells, a process called MEIOTIC NONDISJUNCTION. Meiotic disjunction can occur in either the anaphase stage of meiosis I or meiosis II, however, different outcomes are produced.
When chromosomes fail to separate at meiosis I, it results in two gametes that lack that particular chromosome (n-1) and two gametes with two copies of the chromosome (n+1). This means that the four daughter cells will have an incorrect number of chromosomes, hence, the misalignment of the chromosomes during anaphase I will result in four aneuploid daughter cells.
The correct answer is "<span>they can develop into most types of human cells".
Stem cells are cells that are undifferentiated to what function they may serve, depending on the tissue where it will develop in to. In the context of brain tissue implants, these stem cells can develop into brain cells or nerve cells or neurons which comprises the functional brain tissue; this is clinically significant as neurons are not capable of replacing themselves if damaged.</span>
