Answer:

Gap 2 (G2): During the gap between DNA synthesis and mitosis, the cell will continue to grow and produce new proteins. At the end of this gap is another control checkpoint (G2 Checkpoint) to determine if the cell can now proceed to enter M (mitosis) and divide.

Which of the following does not explain why if two people are exposed to the same high stress causing conditions, there is a lik
e-lub [12.9K]

Answer:

Probably B

Explanation:

They all explain it, honestly, but B sounds the least like an answer they would accept as true. It's also kind of sus that they have 2 different answers about reacting differently to stress, and B is definitely the least likely of the two to be correct. Sorry I couldn't be more helpful, I'm only here because I searched for the answer myself. Good luck.

Rank the sequence of events at the NMJ that initiate an action potential in the muscle fiber, from first to last.
wlad13 [49]

The correct order is:

- Action potential arrives at the axon terminal.

- Calcium ions enter the axon terminal.

- Synaptic vesicles fuse to membrane of axon terminal.

- Acetylcholine is released into the synaptic cleft.

- Acetylcholine binds to its receptors on the junctional folds.

- Junctional folds become depolarized.

- Action potential is initiated on the sarcolemma.

Action potential travels through the membrane of the presynaptic cell causing the channels permeable to calcium ions to open. Ca2+ flow through the presynaptic membrane and increase the Ca concentration in the cell which will activate proteins attached to vesicles that contain a neurotransmitter (e.g. acetylcholine). Vesicles fuse with the membrane of the presynaptic cell, thereby release their contents into the synaptic cleft-space between the membranes of the pre- and postsynaptic cells. Neurotransmitter binds to its receptors on the postsynaptic membrane and its binding causes depolarization of the target cell (muscle cell).

Mr. Whiskers, a cat that loves to eat, has a mass of 39 kg. Mr. Whiskers sees a mouse and decides to chase it, and accelerate at
Sphinxa [80]

Answer:

Force = 78 N

Explanation:

Given data:

Mass = 39 Kg

Acceleration = 2 m/s²

Force generate = ?

Solution:

Formula:

F = ma

F = force

m = mass

a = acceleration

Now we will put the values.

F = 39 Kg × 2 m/s²

F = 78 Kg.m/s²

Kg.m/s² = N

F = 78 N
