Answer:
According to the illustration of meiosis I, when sister chromatids stay together the phase to which it corresponds is telophase I (fourth option).
Explanation:
Meisois is a process of cell division whose final result is the obtention of two daughter cells with half of their genetic charge, with respect to the original cell. This process is divided into two parts, called meiosis I and II.
Telophase I corresponds to the phase of cell division in meiosis I, where the events that occur are the appearance of the nuclear membrane on the newly divided genetic material, cytokinesis -or cytoplasmic division- and above all due to the fact that each daughter cell already contains half of the genetic load, since the sister chromatids stay together.

Answer: If this doesn't help just let me know
The abiotic factors will define which organisms are able or not to live in a specified place. The living organisms will constitute the biotic factors, which define if and how can an organism live in a specified environment. So, the abiotic factors are controlling the biotic factors of an environment.
A. Patient is male because there is a Y chromosome
B. 47 chromosomes
C. Down syndrome or trisomy 21
Answer:
deuterostomes
Explanation:
During the formation of the gastrula, a group of cells migrates towards the inside. The resultant sac forms the embryonic gut. The embryonic gut has an opening that opens to the outside and is called the blastopore. The blastopore may give rise to mouth or anus. In some organisms, blastopore develops into the anus. These organisms are called deuterostomes. The other organisms in which blastopore develops into the mouth are called protosomes. Echinoderms, hemichordates, and chordates are deuterostomes.
Answer:
The correct answer will be option-C
Explanation:
Lead is a metal found in the Earth's crust which through human practices like using it in paints and other products cause lead poisoning in humans due to accumulation of lead in the body.
Lead poisoning can affect the child above 6 years and adults and prove harmful as its increased concentration can cause severe health problems common of which are the development of anaemia due to large consumption, brain damage, reduced mental growth and severe stomach ache.
Thus, Option-C is the correct answer.
