Stem cell therapy has been one of the hotly-debated topics most especially to its ethical value. One of the issues associated with the therapy is that the implantation of stem cells into patients is considered as "unethical." Another issue is that the embryo gets destroyed when stem cells are derived from it.

According to this evolutionary tree, the archaea and eukaryotes last shared a common ancestor ________.
Lostsunrise [7]

Answer:

2.5 billion years ago.

Explanation:

Evolutionary tree is constructed to understand the phylogeny and evolution relationship of the organism. The evolutionary tree is constructed by looking at the molecular and physiology of the different organisms.

The eukaryotes are more closely related to the archaea. Depending on the biochamical and molecular evidence is has been found that they share the common ancestor almost 2.5 billion years ago. This can also be deduced by the fossil evidence as well.

Thus, the answer is 2.5 billion years ago.

Which structure of the nephron reabsorbs the most substances?
omeli [17]

Answer:

Proximal convoluted tubule

Explanation:

The major work of re-absorption is carried out in nephron by the proximal convoluted tubule (PCT). The PCT re-absorbs all the essential nutrients such as amino acid, potassium, glucose etc. and water driven by passive transfer based on concentration gradient. Along with gradient, pH of the urine also affects the re-absorption. Based on the pH of the urine (basic or acid), re-absorption of ionized acid increases or decreases.

What's the most reliable indicator you should use when determining if you should modify activity for heat?
sp2606 [1]

Heath index chart is the best indicator you should use when determining if you should modify activity for heat. The "heat index" is a single value that looks for both temperature and humidity. The higher the heat index, the weather will feel the hotter since sweat does not immediately evaporate and cool the skin. The heat index used is much better than air temperature alone for estimating the risk to workers from environmental heat sources.

Porque un grupo de celulas pequeñas ayudarian a un organismo a mantener la homeostasis mejor que una celula grande?
NeX [460]

Answer:  

Una parte fundamental de la homeostasis es la transferencia y la ingesta de moléculas (sea necesario o no). Es importante que la célula pueda llevar los nutrientes necesarios inmediatamente donde los necesita y poder deshacerse de los subproductos dañinos del proceso celular. Es igualmente importante poder regular la concentración de agua. Las células más pequeñas tienen una superficie más grande en relación con su volumen (su superficie se escala con R ^ 2 mientras que su volumen con R ^ 3 donde R es el radio de una célula) y, por lo tanto, los intercambios a lo largo de la membrana celular se ven favorecidos en comparación con las células más grandes que necesitan muchos intercambios pero tienen proporcionalmente menos área de membranas. Si bien A no es necesariamente cierto, C es definitivamente cierto y, por lo tanto, la respuesta correcta.
