All of these answers are correct.
Explanation:
Answer:
The correct answer would be C.) The cell grows and makes a copy of its genetic material.
Cell cycle can be divided into two phases namely; inter-phase and mitotic phase.
Inter-phase or resting phase is the phase occurs between two consecutive mitotic phases.
It is sub-divided into three phases:
Gap 1 (G₁) phase: The cell actively performs its functions during this phase. It grows in size, transcribe and translate all the enzymes, proteins and other components which are necessary for replication of DNA (deoxyribonucleic acid).
Synthesis (S) phase: It is the phase during which DNA content of the cell is replicated or synthesized. After this phase, the DNA content of the cell doubles however, the chromosome number remains the same.
Gap 2 (G₂) phase: The cell resumes its growth and prepares itself for cell division or mitotic phase. The cell organelles like mitochondria and chloroplasts (in plants) also divide during this phase. The cell continues to grow until it enters mitotic phase.
Hence, we can conclude that the cell grows and makes copy of its genetic material ( usually DNA) before mitosis.
Answer:
After several hours, both beakers are expected to have the same temperature of 65°C
Explanation:
Given that:
The temperature in beaker A = 80°C
The temperature in beaker B = 50°C
The copper rod used to connect allows transference to heat and temperature from beaker A to the beaker B because it is a good conductor of heat and electricity. After several hours, movement of heat and the temperature have occurred and they have both reached equilibrium.
Therefore, after several hours, both beakers are expected to have the same temperature of 65°C
i.e.
= ((80 + 50)/2) °C
= (130/2)°C
= 65 °C
It is part of our nervous system and uses stimuli to respond to an event that is happening. The five senses are motor receptors making you move your muscles to respond to that event that is happending
