Explanation:
a small room in which a prisoner is locked up or in which a monk or nun sleeps.
or if its a living cell: the smallest structural and functional unit of an organism, typically microscopic and consisting of cytoplasm and a nucleus enclosed in a membrane. Microscopic organisms typically consist of a single cell, which is either eukaryotic or prokaryotic.
Answer:
Metaphase (mitosis) and metaphase I ( Meiosis)
Explanation:
In a diploid organism, the chromosomes are present in pair called homologous pair which has to be distributed in the cells during the cell division cycle.
The distribution of the chromosomes in a cell is observed in four subphases: prophase, metaphase, anaphase and telophase.
The homologous chromosomes when are found in a condensed form and are present in the centre of the cell or at the equatorial plate is known as the metaphase.
In case of mitosis since the division takes place in one cycle, therefore, metaphase is the phase whereas in meiosis since the division takes place in two-cycle, therefore, metaphase I is correct as during the metaphase II the chromatids are present at the centre.
Acetylcholine is the neurotransmitter released by cholinergic neurons responsible for contracting muscles (one of the major) and by learning and memory. In the case of muscle contraction, nerve transmission (in this case called neuromuscular transmission) occurs at a site called the neuromuscular junction, where the axon splits into several endings and binds to skeletal muscle fiber. It is the product of the reaction between choline (lecithin component) and acetyl-CoA in the presence of the enzyme choline acetyltransferase.
