Ecosystems can be large and are made of biomes. Some examples of ecosystems are deserts and forests.
The father determines if its male or female. So the father is the carrier and the allele is on the Y chromosome.
Answer:
Relative dating is the technique to calculate the age of an ancient materials in comparison to another material's age. Layer A is less older, if layer B lies beneath it. Layer A may be 2.5 to 3 million years old.
Explanation:
Before discovery of radioactive carbon dating method, geologists make use of relative dating method in order to determine the age of rock or fossils. The relative dating procedure often referred to as stratigraphy. Though this procedure is not capable of predict absolute age or dating. In relative dating, is mainly based on the fact that the older rock layers will be deeper in respect to the less older rock layer.
Answer:
All the above participate in the ammonia excretion
Explanation:
The amino groups present in the amino acids are required to form the urea. The ammonia disposal takes place un the liver by the urea formation and is excreted in the kidneys by urine. When free ammonia is produced in peripheral tissues, it is transported to the liver by glucose -alanine cycle, alanine in transported in the blood to the liver, where is converted into pyruvate.
Another pathway is by glutamine synthase/glutaminase system. The storage and transport of ammonia to the liver is glutamine from glutamate by glutamine synthetase: NH3 + glutamate → glutamine once in the liver glutamine is transformed into glutamate again by glutaminase enzyme: glutamine → NH3 + glutamate.
In the liver takes place the urea cycle, the amino acids transported into the liver can be converted to aspartate. This aspartate enters the urea cycle forming an intermediate of the cycle, and the final product is urea that is excreted by urine.
Answer: the winding structure of the ER results in a large membrane surface area that supports its function
Explanation:
