Answer:
The stomach of a cattle and other ruminants include a pouch like structure called a recticulum, where bacteria help breakdown the animals food.
Explanation:
Cattle is a ruminants and ruminants animals are animals that can chew the cord and have four chambered stomachs. Their stomachs are rumen, recticulum, abomasum and omasum. The abomasum is considered the true stomach because it has a structure similar to that of non ruminants. Recticulum is the second chambered stomach that is pouch like and it contains bacteria they help breakdown food. It collect the small digests molecule and move them to omasum.
It contains 72 percent hydrogen, 26 percent helium and other elements like oxygen, carbon, neon, nitrogen, magnesium, iron and silicon.
Answer:
Resting potential
Explanation:
This is because , the resting potential is negative in side of the cell because it has more negative charge inside than outside due to accumulation of alot of sodium and potassium ions. when an axon is at rest in the cell, the anions produce negative charge, the sodium pumps eject sodium out of the cell and potassium is injected in, and the sodium gates and potassium gates are all closed.
Drosophila melanogaster an excellent model for studying fundamentals of development because many of the genes involved in the development of the fruit fly are also found in humans and the precise formation of each of their 959 body cells has been mapped.
Its many of the genes involved in the development of the fruit fly are also found in humans. Drosophila melanogasteris which is also called Fruit fly is small in size and minimal requirements, many fly's can be raised and tested within a small laboratory which does not have access time, space or funding.
Genetic factors also make this fly an ideal model organism. Drosophila melanogasteris only has four pairs of chromosomes compared to 23 pairs in humans.
