Answer:

Delta binds to the Notch receptor and this binding produces the cleavage of its intracellular domain, which subsequently enters into the cell nucleus to bind with a repressor in order to activate the transcription

Explanation:

The Notch signaling pathway is initiated when Notch receptors on the cell surface bind to the Delta ligand, which activates Notch signaling in cells next to it. In the receiving cell, Delta–Notch binding triggers the cleavage of the Notch intracellular domain called Nic (intracellular Notch). Subsequently, Nic enters into the cell nucleus where it releases repression on Suppressor of Hairless (Su(H)) class transcription factors, thereby activating the transcription of target genes.

In their first attempts to genetically engineer a cow that will make and secrete human growth hormones in milk, scientists found
Arte-miy333 [17]

Answer:

C. The cows will reproduce, but neither males nor females will reproduce the altered gene.

Explanation:

I just had this question lol but because it said in the question “However, they discovered that the altered gene gets lost from the genome during meiosis.” Shows that the cows aren’t able to reproduce the altered gene. It never stated they can’t reproduce.

2. Can the classification system change? If so, provide an example of a way it has changed in the past. (2 points)
Elis [28]

Yes, classification system is still evolving together with our knowledge.

But, before changing the name (e.g. of a species) it is important to collect and gather a wealth of information in order to support that change. Classification system is still evolving. The reasons for the changes are DNA analyzes. It is the new way for discovering relation between organisms and put them in the right context (classification used to be based on morphological characteristics).

Change in classification can be shown in an example of fungi. In the 90s fungi classification included only phyla Chytridiomycota and Zygomycota. Now theyhave been classified mainly on the basis of characteristics of their sexual reproductive structures. So, there are 7 phyla now: Microsporidia, Chytridiomycota, Blastocladiomycota, Neocallimastigomycota, Glomeromycota, Ascomycota, and Basidiomycota
