Charged amino acid side chains can form ionic bonds, and polar amino acids are capable of forming hydrogen bonds. Hydrophobic side chains interact with each other via weak van der Waals interactions. ... When connected together by a series of peptide bonds, amino acids form a polypeptide, another word for protein.
Hi there!
Meiosis is a type of reproduction where two divisions occur. It is when gametes, sex cells, divide. In prophase of meiosis, it is similar to that of mitosis, as in the spindle fibers develop as well as centrioles. First, homologous (pairs) of chromosomes line up in the center of the cell. Next, spindle fibers pull the pairs apart, leaving one chromosome of each pair on each side. Then, the nuclear material divides as the spindle fibers and centrioles go away. Lastly, the cytoplasm divides, leaving two cells. Meiosis two starts out with prophase again. In prophase, the DNA condenses and forms short chromosomes as well as spindle fibers and centrioles developing. Next, the chromosomes (there is only one chromosome, made up of two sister chromatids) line up in the center of the cell. Next, the spindle fibers pull the chromosomes apart, pulling one chromatid to each side of the cell. Then, the nuclear material divides and the spindle fibers and centrioles disappear. Lastly, the cytoplasm divides, leaving four cell in total.
Hope this helps!! :)

It is a true statement that even though nearly 200 nations have adopted the Universal Declaration of Human Rights, in many nations theserights are frequently abused. The correct option among the two options that are given in the question is the first option. I hope the answer has helped you.
Answer: 11 to 16mls
Explanation:
It's obvious, you'll be thinking of African or European swallow; we might consider the West African swallow, or the South African Cave swallow, however, choosing one between these two would be completely arbitrary- and neither is it sufficiently studied to provide the absolute data we need.
Notwithstanding, there is an accepted way to estimate the airspeed of a bird using Strouhal ratio's equation. This states that "the frequency of wingbeats multiplied by their amplitude and divided by the airspeed of the bird provides a semi-constant value." This is known as the Strouhal number and averages between 0.2 and 0.4 for most birds, with a higher number denoting a less efficient flight pattern.
Flight is (for those poor people who we're not opportune to watch it) clearly very efficient, seeming almost effortless. So we’ll go for the lower end of Strouhal numbers in our working, giving us (drumroll please), an airspeed velocity of 11–16 metres per second. That’s 40–60 kilometers per hour.
The use of evidence to construct explanations is call scientific explanation
