The answer is B. The hawks no longer have competition and the rabbits have one less predator.
The branch of the posterior descending artery that supplies blood to the inferior chamber of the heart. The LMCA supplies blood to the left side of the heart.
<h3>What is the arterial network?</h3>
The circulatory system, also known as the vascular system, is made up of the blood and lymphatic vessels that transport fluid throughout the body. In addition to delivering oxygen and nutrients to the tissues and eliminating waste from the cells, the arteries and veins move blood throughout the body.
<h3>Which organ has arteries in it?</h3>
The blood vessels known as arteries carry oxygen-rich blood from the heart to all of the body's cells. They are a part of your cardiovascular system, which circulates your blood. For your body to receive nutrition, hormones, and oxygen, they are necessary.

Answer:
a mutation that blocks the GTPase activity of Ras
Explanation:
A G protein in inactive state is GDP bound but as soon as a guanine exchange factor (GEF) exchanges it with GTP it gets activated which means that in GTP bound state it is active. G - protein has endogenous GTPase activity. Upon interaction of GAP, the GTPase activity of this protein is exhibited. When GAP is present, hydrolysis of GTP into GDP occurs which leads to inactivation of G protein. A mutation which will block GTPase activity of Ras will therefore result in constitutive active signaling even in the absence of ligand binding to it's receptor. In such scenario, GTP will not be hydrolyzed into GDP so signaling will be up-regulated.
