Which site in the digestive tract produces chyme? STOMACH

Kazeer [188]4 years ago

Chyme is actually produced both in the stomach and the small and large intestines of the digestive tract. This thick semifluid mass or digestive juice is responsible for breaking down the food and making it easily passable into the intestinal walls. Chyme is also responsible in preventing the gastric juices of the stomach to attach its own and within the intestines it breaks down food into proteins, starches, and fibers.

The synthesis of nucleotides requires several amino acids. Sort each amino acid as a precursor in the synthesis of purines, pyri
Lapatulllka [165]

Answer:

Glycine is required for purines, aspartate for pyrimidines, glycine and aspartate for both purines and pyrimidines. The remaining amino acids are not required for the synthesis.

Explanation:

Nucleotides are the monomer for the synthesis of DNA and RNA. The two main class of nitrogenous bases are purines and pyrimidines. These nitrogenous bases require the amino acids as a precursor for their synthesis.

Glycine is the simplest amino acid and required for the synthesis of purines. Aspartate is required for the synthesis of pyrimidines. Glutamine and aspartate are required for the synthesis of both purines and pyrimidines. Lysine, leucine, alanine, histidine, methionine, tryptophan and alanine are not used as a precursor for the nucleotides.

A lab assistant needs to mix up the following reaction to prepare DNA for an experiment:_________.
lara31 [8.8K]

Answer:

Explanation:

The total solution formed after mixing the components will be

20 μl + 20 μl + 40 μl + 120 μl = 200 μl

The smallest size tube that will hold the entire reaction is:

Firstly convert 200μl to ml

1000 μl = 1 ml

200 μl = X

X = 200 x 1/1000

X = 0.2 ml

The smallest size tube (from the options provided in the question) is 0.25 ml.

The pipetting device that could be used to accurately measure all the needed volumes must be able to measure 20 μl, 40 μl and 120 μl.

The best pipette to accurately take these measurements individually is the P200 micropipette because it has an accurate/useful range of between 20 μl - 200 μl

Mnenie [13.5K]

The answer is natural selection.

In natural selection, genotype variations that will increase the chance of survival and reproduction of some organism are preserved and will be inherited. Red and green colors of butterflies increased the chance of their <span>survival and reproduction, so these traits will pass to the next generation.</span>
