Answer:
"When the hypothalamus senses that you're too cold, it sends signals to your muscles that make your shiver and create warmth."
Answer:
D. same number as adenines
Explanation:
As mentioned, adenines match with thymines and cytosines match with guanines, so there will always be the same quantity of guanine and cytosine and the same quantity of adenine and thymine.
Cells free Protein expression is described below.
Explanation:
- laboratories came to adopt the technique for protein synthesis for the purposes of answering the age-old question: exactly what role do amino acids play in proteins? Scientists Marshall Nirenberg and Heinrich Matthaei made a huge breakthrough in the answer to this fundamental question in 1961, successfully applying cell-free protein expression to make the connection between nucleotide triplets and the amino acids they encode.
- Using an in vitro translation system based on E. coli, they were able to synthesize the polypeptide polyphenylalanine. From there, they were able to determine the connection between the amino acid phenylalanine and its corresponding codon UUU, essentially discovering the key to cracking the genetic code. This groundbreaking experiment would eventually lead to the deciphering of all the remaining amino acid codons and laid the foundation for the wide variety of translation biology systems that are available today
- Cell-free expression begins with crude extracts generated from cultured cells that are typically engaged in a high rate of protein synthesis, such as immature red blood cells (reticulocytes). These crude extracts are depleted of their endogenous DNA and mRNA, and the cell lysate is subsequently supplemented with macromolecular components required to perform translation, including ribosomes, tRNAs, aminoacyl-tRNA synthetases and initiation, elongation and termination factors.
Answer & Explanation:
- One of the biggest differences between these two groups of monkeys is their tails. On one hand, some species of New World monkeys possess prehensile tails, meaning they can use their tails to grasp or hold on to objects. Their tails can aid these monkeys in finding and eating food in the canopy as well as moving amongst the trees, as their tails provide extra support and balance.
- On the other hand, Old World monkeys all have tails, but they lack the ability to grasp objects. However, some Old World monkeys have pads called ischial callosities surrounding their hind region. As these monkeys tend to spend more time on the ground than their arboreal New World counterparts, these calloused areas of skin provide support when they sit to feed or rest.
