Answer:
what is the question? please let me know
Answer:
The question to be asked an investigated when observing a structure under the microscope to determine whether it is living is if it has a nucleus if eukaryote or nucleoid if prokaryote.
Explanation:
The major organelle that must be present in all living cells is the nucleus or nucleoid and the protoplasm. The observation of the cell under the microscope will show the subcellular entity, nucleus/nucleoid, more pronounced than other organelles in the cell. The nucleus house the necessary information for the maintenance and reproduction, which is mainly the genetic information that dictates the translational protein products that are needed to build another aspect of the cells. Therefore, when such a tiny structure is placed under the light microscope under the view of oil immersion, the nucleus of the cell should be visible if it is a living structure.
Answer:
The correct answer is A DNA is replicated before mitosis begins
Explanation:
DNA replication is one of the most significant event of a cell cycle. .DNA replication occur in the S phase or synthesis phase of the cell cycle.
DNA is replicated once per cycle to maintain to normal chromosome number in daughter cells.
DNA is replicated to form two new DNA molecules which are then equally distributed in each daughter cell during the mitosis phase.
Answer:
a. Diameter of afferent astride is bigger than efferent arteriole to generate force for efficient filtration
b. Urine is slightly thicker in summer than in winter to reduce water loss from the body
c. Always vasopressin is not secreted when a person drinks sufficient water
d. ESRD stands for End stage renal disease
Explanation:
a. While transferring blood from afferent astride to efferent arteriole blood gets filtered. Filtration is efficient when the blood flows with force which is generated when blood flows from large arteriole to the small arteriole. Hence the diameter of afferent astride is bigger than efferent arteriole.
b. Urine is slightly thicker in summer than in winter to reduce water loss from the body. In summer water is lost in the form of sweat as well. Hence, urine gets concentrated to compensate for the lost body fluid.
c. Always vasopressin is not secreted when a person drinks sufficient water. The osmoregulation is maintained externally.
d. ESRD stands for End stage renal disease
When half of the shape is black it means the person is a carrier. When the whole shape is black this means the person has the disorder.
d.100%
