Scientists believe that ancient ancestors of all animals were single celled eukaryotes that sometimes grew in colonies. The correct option among all the options that are given in the question is the second option or option "B".
The Cambrian Explosion resulted in the evolution of the first representatives of most animal phyla. The correct option among all the options that are given in the question is option "B".
Answer:
Glut4 is only expressed in insulin-sensitive skeletal an heart muscles and fat tissues.
Explanation:
Glucose transporters represent a group of integral membrane proteins that allow the transport of glucose molecules across the plasma membrane by the mechanism of facilitated diffusion (i.e., without direct coupling to ATP hydrolysis). In humans, the Glucose Transporter type 4 (GLUT-4) is a glucose transporter encoded by the SLC2A4 gene. This protein plays a critical role in regulating glucose homeostasis by enabling to increase the transport of glucose in response to elevated blood insulin levels in adipocytes, skeletal and cardiac muscle tissues.
What are your answer choices?
There are number of endemic species, because island isolation promotes allopatric speciation and the latter occurs when species become separated from each other to the level that prevents genetic recombination.
