Answer:

During synthesis phase DNA replication occurs to doubles the amount of DNA.

Explanation:

Interphase is the phase where the cell spends most of its time. Interphase is divided into three-phase which are G1, S, and G2 phase. The cell grows and produces enzymes required for DNA replication in G1 PHASE.

The synthesis (S) phase is the phase where the DNA replication takes place. Due to DNA replication, the amount of DNA gets doubled in this phase. DNA replication is important because after mitosis cell divides into two daughter cell in which the two DNA divides equally which creates two identical cell after cell division.

A black mamba snake has a length of 2.67 m and a top speed of 3.96 m/s . Suppose a mongoose and a black mamba find themselves no
Papessa [141]

Answer:

time (t) = 2.69 sec

Explanation:

Given that;

The final top speed of 3.96 m/s ( final velocity V) = 3.96 m/s .

The initial speed is 0; &

The acceleration (a) = 1.47 m/s²

We can determine how much time does it take the snake to reach its top speed by using the equation of motion;

V = U +at

3.96 = 0 + (1.47×t)

3.96 = 1.47t

t = \frac{3.96}{1.47}

time (t) = 2.69 sec

∴ It took the snake  2.69 sec to reach the its top speed.
