This is true. Urea carries the bloodstream to your kidneys which then transport waste along with water to form urine.
Answer:
Hundreds of proteins have been sequenced by Edman degradation of peptides derived from specific cleavages. Protein Mass Spectrometry is an analytical technique that measures the mass-to-charge ratio of charged particles for determining masses of particles and the elemental composition of a sample of molecules as well as for elucidating the chemical structure of molecules such as peptides. Protein mass spectrometry is an important method for the accurate mass determination and characterization of proteins, and a variety of methods and instrumentations have been developed for its many uses.
Answer:
The correct answer would be (c)[m phase].
M phase or mitotic phase is the phase of the cell cycle in which the actual division of chromosomes (karyokinesis) into two daughter nuclei takes place.
It can be divided into four stages namely prophase, metaphase, anaphase, and telophase.
During anaphase, the sister chromatids of each replicated chromosomes are separated from each other and are pulled in opposite side with the help of mitotic spindle.
Then during telophase (last stage of M phase), the separated chromosomes reach either pole of a dividing cell. In addition, nuclear membranes are reformed around each chromosome set which forms the two daughter nuclei.
M phase is followed by cytokinesis which divides the cytoplasm, cell organelles, cell membrane, and two daughter nuclei into two daughter cells.
Note: Chromosome duplication or replication takes place in S phase while the division of the replicated chromosomes takes place in M phase.
Answer:
A) Elastin
Explanation:
Elastin is the principle load-bearing protien present in the wall of aorta. It is the protien which coil and recoils like a spring within the elastic fibres and accounts for elasticity of blood vessels. As during excerise , afterload is increased ,thus a stretch is produced in the vessels. Similarly im warm environment the vessels dilate this this stretch is produced by elastin.
Answer:
Silica
Explanation:
A unique feature of diatom anatomy is that they are surrounded by a cell wall made of silica (hydrated silicon dioxide), called a frustule
Hope this helps!
