The____of cattle and other ruminants includes a pouchlike structure called a(n)____, where bacteria help break down the animals

Alex_Xolod [135]

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.

Meselson and Stahl used density labeling of DNA to show that DNA replication occurs via a semiconservative mechanism. In their e

Answer:

The organism previously used 15N for replication so all the DNA molecules were of 15N15N type. Then the organism is shifted to a medium where only 14N is available for replication.
According to semi conservative mode of replication, a newly synthesised DNA molecule consists of one new strand and one parental strand. So after the first round of replication, All the 15N strands will synthesise new DNA strands using 14N resulting into intermediate 15N14N DNA molecules. Hence, only one band would be observed (15N14N) above the original 15N15N band since 15N14N has lighter isotope too so it will be lighter than 15N15N molecules and will lie above it.
After second round of replication, 15N strand from 15N14N would synthesise another 14N strand. 14N strand from 15N14N molecules will also synthesise another 14N strand. So now, 50% of the DNA molecules will be of 15N14N intermediate type and 50% of them will be of 14N14N type.Two bands will be observed above the original 15N15N band. One band of 15N14N molecules will be right above it and other band of 14N14N molecules will be even higher because it is the lightest band since it has only the lighter isotope of nitrogen.
