Answer:
Chromosomes were first named by cytologists viewing dividing cells through a microscope. The modern definition of a chromosome now includes the function of heredity and the chemical composition. A chromosome is a DNA molecule that carries all or part of the hereditary information of an organism. In eukaryotic cells, the DNA is packaged with proteins in the nucleus, and varies in structure and appearance at different parts of the cell cycle.
Explanation:
Cells reproduce genetically identical copies of themselves by cycles of cell growth and division. The cell cycle diagram on the left shows that a cell division cycle consists of 4 stages:
G1 is the period after cell division, and before the start of DNA replication. Cells grow and monitor their environment to determine whether they should initiate another round of cell division.
S is the period of DNA synthesis, where cells replicate their chromosomes.
G2 is the period between the end of DNA replication and the start of cell division. Cells check to make sure DNA replication has successfully completed, and make any necessary repairs.
M is the actual period of cell division, consisting of prophase, metaphase, anaphase, telophase, and cytokinesis.
Answer:The correct answer is letter A.
Explanation: he is right
Your teacher gives you an unknown protist to classify that is currently inactive. The protist appears to have long lash-like
appendages protruding from its cell surface. Which kind of locomotion can we expect from this protist? (1 point)
The appendages of this protist will move in a dragging motion that actively pulls the protist forward.
O The appendages of this protist will move in a sweeping motion like oars to actively propel the protist forward.
The appendages of this protist will move back and forth like a wagging tail to actively propel the protist
forward
O The appendages of this protist are not functional, and the protist moves passively via environmental forces.
A because if you add and do the equation to all the cups
The answer is B.) its reactivity
the answer is B. because the Roman's were frequently conquering their surrounding territories for greater power, they found it necessary to document medical procedures for future generations to learn these skills and keep their armies in good health for the next battle.
