Answer:
We mean that a cell changes to another type of cell.
Explanation:
<em>Stem cells </em>are a type of cell that has the potential to become a specialized cell, this change or differentiation, is possible thanks to the activation or deactivation of certain genes that promote (or inhibit) the expression of certain proteins that origins different types of cells (fmuscle cells, osteocytes, neurons). This differentiation happens when the cells receive cues internally ( through signals or contact between a group of cells and another or through transcription factors) or externally.
Then, a differentiated cell is a cell that had gone under the previously described process.
I hope this information is useful to you!
I believe your answer is B :)
Father: XY
Mother: XX’
The father is normal, while the mother is a carrier.
Answer:
A graph not only depends on the data that we are graphing, there are other important factors such as the units we use (here we have °C vs years, but we could have °F vs days and we would see a different graph, which represents the exact same information) , the scale we use (a lot of graphs are misleading because of the use of logarithmic scales, we need to be clear about the scales we use), where we put the zero of each axis (We usually use the intersection of both axes as the (0, 0) point, but this is not a necessary condition, we could manipulate our coordinate axis as we want) , etc.
So there are a lot of things that can impact on how we see the graph of the same data.
About the second answer, one could interpret from that graph that the actual temperature between the years 1880 and 2020 was around 14°C.
Answer:
B) nuclei of gland cells.
Explanation:
DNA carries the blueprint for the production of all the proteins including enzymes in human beings. Humans are eukaryotes and their DNA is present in the nucleus of their cells. All the cells that make the complex human body are derived from division in the zygote and therefore, are genetically identical and have the same DNA.
However, gene expression is regulated by the expression of specific genes in specific cells and at a different time of developmental stages. Amylase is the enzyme that digests starch in humans. Amylase is secreted by salivary glands. So, the nuclei of these glands would have genetic information for the synthesis of amylase.
