Which organisms, out of fish, chicks, mouse, and human embryos, would be more closely related and which would be less closely re
Rainbow [258]

Answer:

the chicks and mouse would be losely conected because they have more of the same gentic material and fish and humans would havwe the same since they kind act like the same because The recent advances in developmental biology described  have established the central importance of a small number of highly conserved signal transduction pathways that mediate cell interactions crucial for animal physiology, reproduction, and development. It seems likely that many developmental toxicants might affect development by acting on those pathways. Application of the methods that have been so successful in elucidating them should now allow scientists to investigate that possibility and to determine the mechanisms by which developmental toxicants act. This chapter reviews the experimental approaches primarily responsible for the recent advances in knowledge about animal development and discusses how those approaches might be applied to developmental toxicology. Chapter 8 discusses how those approaches might lead to improved qualitative and quantitative risk assessment.

How is perspiration related to recovery after exercise?
lys-0071 [83]
I would say that the way perspiration is related to recovery after exercise is that the body replenishes water and ions during perspiration so the muscles can rest and repair during the cool down period.

Skin cells form new cells in<br> Mitosis only<br> O Meiosis only<br> Both<br> Neither
Fiesta28 [93]

Answer:

Mitosis only

Explanation:

Mitosis and meiosis are both types of cell division. Mitosis allows cells to proliferate for growth and repair. So this is how skin cells form new cells.

Meiosis is a type of cell division specific to reproduction. It forms the gametes, which are the egg and sperm. It generates haploid cells that fuse via fertilization to create a zygote.
