Compare the limbs of different organisms goes in left box. compares fossilized structures to living organisms left box.
other 2 go in the right box hope this helped(:
A. two identical nuclei
<span>Mitosis, simply put, is the division of the nucleus of a cell. It is the phase in the cycle of a cell in which the two chromosomes in a cell divide and separate in a nucleus of their own. These chromosomes are completely identical. As a result of mitosis, two identical cells are formed and are known as daughter cells. This process copies and transfers DNA into both the cells that are formed as a result of Mitosis.</span>
The earliest life forms we know of were microscopic organisms (microbes) that left signals of their presence in rocks about 3.7 billion years old.
Answer:
Juxtaglomenular is a structure in the kidney which regulates the function of each nephron, the functional units of the kidney. The main function of the juxtaglomerular cells is to secrete renin in response to:
Stimulation of the beta-1 adrenergic receptor
Decrease in renal perfusion pressure (detected directly by the granular cells)
Decrease in NaCl concentration at the macula densa, often due to a decrease in glomerular filtration rate
Explanation:
The juxtaglomerular apparatus is a specialized structure formed by the distal convoluted tubule and the glomerular afferent arteriole. It is located near the vascular pole of the glomerulus and a structure in the kidney that regulates the function of each nephron, the functional units of the kidney.
Enzymes are regulated by more than the binding of small molecules. A second method that is used all the time by eucaryotic cells to regulate a protein's function is the covalent addition of a phosphate group to one of its amino acid side chains. These phosphorylation events can affect the protein in two important ways.
