Answer:
tertiary; quaternary
Explanation:
The orientation of all the atoms of a protein in three dimensions represents its tertiary structure. It includes the folding of the polypeptide chains in a way that brings are far apart amino acids of its secondary structure close together. Various segments of a polypeptide chain interact to form tertiary structures and these segments are held together by different kinds of weak interactions.
However, disulfide cross-links between the segments of polypeptide chains also stabilize the tertiary structure of some proteins. Likewise, disulfide bonds also hold the protein subunits of some proteins together and thereby, contribute to the quaternary structure. For example, two light chains of an antibody are joined together by disulfide bonds.
Answer:
62 chromosomes.
Explanation:
Sex cells are formed undergoing meiosis, which means that they contain a haploid number of chromosomes. (Half the number that somatic/body cells contain). 31 is half of 62, which means that the diploid number of chromosomes in the body cells of a giraffe would be 62.
I would try to contain then kill all the lion fish. i would evaluate it by seeing how many dead lion fish body's i can get out of the water.
Answer:
1. B
2. C
Explanation:
1. Stem cells have a higher potency than differentiated cells. They are pluripotent and multipotent cells that can differentiate into most types of cells. Therefore they can be used to repair injuries that take long to heal naturally. An example is applying stem cells on joints of people with arthritis to enable cartilage of knee caps regenerate.
2. Bionics is a form of engineering that mimics human physiology but is not made of tissues but rather mechanicals made of a material like titanium. An amputee, for example, will have a mechanical arm or leg on the amputated limb that functions like a real limb. Usually, in the best form of bionics, the subject is able to control the artificial limb with their mind.
Answer: English
A eukaryote contains a well-defined nucleus, whereas in prokaryotes, the chromosome lies in the cytoplasm in an area called the nucleoid. In eukaryotic cells, DNA and RNA synthesis occur in a separate compartment from protein synthesis. In prokaryotic cells, both processes occur together.
Explanation: Espanol (Spanish)
Un eucariota contiene un núcleo bien definido, mientras que en los procariotas, el cromosoma se encuentra en el citoplasma en un área llamada nucleoide. En las células eucariotas, la síntesis de ADN y ARN se produce en un compartimento separado de la síntesis de proteínas. En las células procariotas, ambos procesos ocurren juntos.
