Answer:
Explained
Explanation:
The proteins(sometimes are called celluar ligands) outside the cell can bind to a receptor protein( generally found on the cell membranes) on the cell surface, causing it( receptor protein) to change the shape and sending a signal inside the cell.
A protein exterior to a cell can influence intracellular processes through receptors on the cell's surface. This change can affect DNA transcription, regulate cell cycle, or stimulate cell death. Malfunctions in these proteins can lead to health issues like cancer, asthma, and hypertension.
A protein outside the cell can cause events to happen inside the cell with the help of the protein receptors on the cell's plasma membrane. When a molecule binds to the receptor on the cell's surface, it triggers a change in the receptor's structure. This change then affects the microfilaments inside the cell, which in turn initiates a series of chemical signals inside the cell affecting the transcription of DNA. This process can regulate activities such as the cell cycle or initiate cell death, also known as apoptosis, under certain conditions.
For example, external events such as cellular crowding or hormonal changes can influence cell division. Another example can be seen in T-cells. They target foreign cells for destruction by the immune system. If these T-cells accidentally target the cells of their own organism, this can lead to autoimmune diseases. In such cases, the T-cell binds to the 'self' proteins which triggers apoptosis to remove the harmful cell.
Errors in the structure of these receptor proteins can lead to various health issues like hypertension, asthma, heart disease, and cancer.

The amplitude of the pendulum is 5cm.
Amplitude is the maximum displacement of the wave from its mean position upwards or downwards.
As the graph of the motion of pendulum swings from +5cm to -5cm for each cycle, the magnitude of peak amplitude of the pendulum is 5 centimeters.

Answer: 192.9N and 91.1N
Explanation:
Let the force exerted by one person = X
Let the force exerted by the other person = y
Then, we can create equations
When both persons pull in the same direction, then
X + Y = 200 * 1.42
When both persons pull I'm opposite directions, then
X - Y = 200 * 0.509
Now we have
X + Y = 284
X - Y = 101.8
When we add the 2 equations together, we get
2X = 385.8
X = 385.8/2
X = 192.9
If x = 192.9, then, y = 284 - x
Y = 91.1
Therefore, one person exerts 192.9N, and the other exerts 91.1N
W = mgh.
m is mass in kg,
g is acceleration due to gravity = 9.81 m/s²,
h is height = 12 m
= 3.8 * 9.81 * 12
= 447.336 Joules
2X + 2Z = 10Y
Z equals 10, when substitute X = 5 and Y = 3 in 2X + 2Z = 10Y.
Arithmetic operations can also be specified by the subtract, divide, and multiply built-in functions.
* Multiplication operation: Multiplies values on either side of the operator
For example 4*2 = 8
/ Division operation: Divides left-hand operand by right-hand operand
For example 4/2 = 2
Given that equation as:
⇒ 2X + 2Z = 10Y
If X = 5 and Y = 3,
Substitute the values of X = 5 and Y = 3,
⇒ 2(5) + 2 (Z) = 10(3)
Apply the multiplication operation
⇒ 10 + 2Z= 30
⇒ 2Z = 20
⇒ Z = 20/2
Apply the division operation
⇒ Z = 10
Hence, Z equals 10, when Substitute X = 5 and Y = 3 in 2X + 2Z = 10Y
