The signal for apoptosis can come from outside or inside the cell. Give one example when the signal comes from outside the cell

and two examples of cellular occurrences that would prompt an apoptosis signal from inside the cell.

Answer:

- A signal for apoptosis that comes from outside the cell is when a cell detaches from extracellular matrix. If this happens, a transmembrane signal is triggered.

- Two examples of cellular occurrences that would prompt an apoptosis signal from inside the cell are:

1. Damaged DNA

2. Increase of cytosolic calcium concentration

Explanation:

Apoptosis can be activated from an intrinsic or an extrinsic pathway. The intrinsic pathway is activated when a cell senses stress (for example, damaged DNA or high cytosolic calcium concentration) and triggers death proteins to activate apoptosis mechanism inside of it; the extrinsic pathway refers to the apoptosis triggered by signals that come from other cells. In this scenario, ligands bind to cell-surface death receptors and activates a death-inducing signal.

Licemer1 [7]

Answer:

<h2>Helicase,  topoisomerase ii /gyrase, single strand binding proteins.</h2>

Explanation:

DNA replication is the process in which DNA is replicated with the help of various enzymes and proteins..

Helicase is the enzyme which unwind the DNA strands, After unwinding, topoisomerase removes these twists. Single strand binding proteins  stabilize the single strands of DNA during replication.

If a postsynaptic neuron is stimulated to threshold by spatial summation this implies that ________. If a postsynaptic neuron is
Maslowich

Answer:

The postsynaptic cell has many synapses with many presynaptic neurons

Explanation:

Spatial summation is a process of producing an action potential in a neuron with input from multiple presynaptic nerve cells. This process determines whether an action potential will be triggered upon reaching threshold from multiple synapses with presynaptic neurons. Summation of all inputs determines if an action potential will b generated.

juin [17]

Answer:

The correct answer is "Statistical Hypothesis".

Explanation:

Given the example, the breeder wants to find the relationship between the two variables which are the effects of bredding and the face length of the boxer breed. He/She is using the statistics of the face length from the years 1915 and 2015 so the type of hypothesis that should be used is "Statistical Hypothesis" which is used when the hypothesis can be verified statistically. I hope this answer helps.
