Answer:
III. Condensation of chromosomes begins.
I. Synapsis occurs.
II. Crossing-over is completed.
IV. Separation of homologous chromosomes begins
Explanation:
The prophase I of meiosis I begins with the condensation of chromosomes. The process of compaction makes the individual chromosomes visible and the stage is called leptotene.
Leptotene is followed by zygotene of prophase I during which the homologous chromosomes are paired together. The process is mediated by the synaptonemal complex. As the homologous chromosomes are paired, each pair is visible as a tetrad as each of the chromosomes of a pair has two sister chromatids.
The exchange of part of chromatids occurs during crossing over. Crossing over is the event of the pachytene stage of prophase I. After crossing over, the homologous chromosomes begin to separate from each other during diplotene but stay paired at the points of crossing over. These points are called chiasmata. Diakinesis of prophase I is marked by the dissolution of chiasmata.
The answer to this question is b
Answer:
A sperm cell
Explanation:
A diploid cell has 46 chromosomes which is normally signified by somatic cells. Germ cells or gametes are haploid cells therefore they contain only 23 chromosomes. Male gamete contains 22 autosomes and one sex chromosome. That sex chromosome can be X or Y.
Female gamete does not have Y chromosome as a sex chromosome, it has only X chromosome as a sex chromosome. So Y chromosome in a human cell which have 22 autosomes determines that it is a male gametic cell or a sperm cell. Sperm cells that have a Y chromosome if fuses with female gamete produce male offspring(XY).
So the correct answer is- a sperm cell.
Metres are exactly 100 cm in length, the easiest way to go from metres to centimetres is to simply add the extra 1 or 2 zeros, so 4.5 metres would be 450 centimetres.
As for the millimetres, 1mm is equal to 0.1cm, once again, just move the decimal forward by one numeral, and you'll have the converted value, making 50mm = 5.0cm.
Your shark would be 450cm long and have teeth with an average length of 5cm.
