Answer:
The. Two populations of sculpin lived on Lake Baikal, but a genetic change in one of the populations prevented them from crossing, thus creating a new species of sculpin.
B. The additional information I would use to test the hypotheses would be: 1) is there any species of fish similar to sculpin in the same lake? 2) what is the genetic change presented by the sculpins?
Explanation:
My hypothesis about sculpin fish states that sympathetic speciation has occurred. This speciation occurs when two populations of the same species can no longer promote crossings between them, thus creating an evolutionary process, which results in the creation of two distinct species, in the same habitat. I believe that this type of speciation is more common to happen in aquatic environments and in fish, since these environments present less physical barriers than the terrestrial environment. This usually occurs with the existence of genetic modifications within one of the populations. As a result, to test my hypothesis, I would need information about the existence of species similar to sculpin within the same lake, in addition to knowing what genetic differences between them would promote this type of speciation.
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.
The answer is ATP.

Answer:
is it pneumonia
Explanation:
i think it is this but am not sure
Answer:
Explanation:
Fertilization occurs when the nucleus of both a sperm and an egg fuse to form a diploid cell, known as zygote. The successful fusion of gametes forms a new organism.
