dawson pe, muir tw, clark-lewis i, kent sb (1994) synthesis of proteins by native chemical ligation. science 266(5186):776–779
Native backbone proteins of average size can now be directly synthesised using a straightforward approach. An initial thioester-linked species is produced by the chemoselective reaction of two unprotected peptide segments. This transient intermediate spontaneously rearranges to produce a full-length product with a native peptide bond at the ligation site.
What is Chemical ligation ?A group of procedures known as chemical ligation are employed to build lengthy peptide or protein chains. It comes after the first step in a convergent strategy. First, standard chemical peptide synthesis is used to create smaller peptides with between 30 and 50 amino acids. They are then totally unprotected after that.
A technique for protein semisynthesis known as expressed protein ligation typically entails the interaction of recombinant protein C-terminal thioesters with artificial peptides that contain N-cysteine in a chemoselective ligation.Learn more about Chemical ligation here:

Please answer this if u know it, thank you❤️
Explanation:
Single circulation is less efficient as gill capillaries slow down the blood flow so the body receives blood at a low pressure which decreases the oxygen supply to the cells.
Double circulation is more efficient as blood at higher pressure especially in humans and mammals
In single circulation only venous blood passes through the heart.
In double circulation mixed or oxygenated or venous blood passes through the heart.

Based on the information provided;
the wavelength of the wave is 5 meter.frequency of the wave = 0.05 HzWave velocity = 0.25 m/sWhat is the wavelength of the wave?The wavelength of a wave is the distance between successive crests or troughs in a wave.
A crest in a wave is a point on the wave surface where the maximum upward displacement of the medium occurs.
A trough in a wave, is the point of the maximum downward displacement of the wave.
The distance between crests in the wave is given as 5 meters.
Thus, the wavelength of the wave is 5 meter.
The frequency of a wave is the number of complete cycles completed by the wave in one second.
From the given data, the wave takes 20 second to complete one cycle.
Therefore, frequency of the wave = 1/20
frequency of the wave = 0.05 Hz
The wave velocity or wave speed is the product of the wavelength of a wave and the frequency of the wave.
Wave velocity = 5 * 0.05
Wave velocity = 0.25 m/s

Why are ecosystems with grass better for herbivores than ecosystems with trees?
Trees cannot store a lot of energy in the leaves, so grass would be better.
Some herbivores can't climb trees, so grass is convenient. Grass also produces oxygen at a far greater rate than trees do

Hybridization is the combination of two or more ____________ orbitals to form the same number of ____________ orbitals, each having the same shape and energy.
The combination of two or more atomic orbitals results in the same number of hybrid orbitals, each with the same shape and energy, which is the right response.
The process of two complementary single-stranded DNA or RNA molecules joining together to generate a double-stranded molecule is known as hybridization in the field of genomics. Correct base pairing between the two single-stranded molecules controls the bonding. Determine how many lonely pairs are connected to it. Add up these two numbers.
Add up these two numbers.
Your atom is a sp3 if the response is 4.

jochmanova i, yang c, zhuang z, pacak k. hypoxia-inducible factor signaling in pheochromocytoma: turning the rudder in the right direction. j natl cancer inst. 2013;105(17):1270-83
An adrenal gland can develop an uncommon, often benign (noncancerous) tumor called a pheochromocytoma.
A (pseudo)hypoxic signature is seen in many solid tumors, such as paraganglioma (PGL) and pheochromocytoma (PHEO). It has been demonstrated that (pseudo)hypoxia encourages the development of tumors and therapeutic resistance. Hypoxia-inducible factors (HIFs) are the main mediators of the transcriptional hypoxic response.The transcription of hypoxia-responsive genes, which are involved in cancer, is induced by high levels of HIFs. Catecholamine-producing tumors called PHEOs and PGLs develop from sympathetically or parasympathetically generated chromaffin tissue. HIF signaling appears to be crucial for the growth and development of PHEOs and PGLs, which may point to novel therapeutic strategies for the management of these malignancies.Learn more about the pheochromocytoma with the help of the given link:

What mistake did john needham make that caused him to conclude that spontaneous generation for microorganisms occurred?.
John Needham made a mistake of re-contaminating his solutions made from cooked broth.
Needham firmly believed in the spontaneous production of microbes, as did many other scientists of the age. In 1750, he reported the findings of an experiment he had carried out in the hopes of proving the theory of spontaneous generation. His research showed that there was spontaneous generation.By executing an experiment in which he put a broth or gravy inside a container, heated the bottle to kill anything within, and then sealed it, John Needham in England refuted Redi's findings. A few days later, he revealed that there was life in the soup and declared that life had been fashioned out of nothing.However, he did a mistake where he accidentally re-contaminated his solution.
