In an controlled experiment, why is it important to change just one variable at a time

1 answer:

If you change more than one variable at a time, then you will have a harder time trying to figure out why the certain change occurred.

List the quantum numbers associated with all of the 5d orbitals

Whitepunk [10]

Answer:

Here's what I get

Explanation:

If the orbital is 5d, n = 5 and l=2.

mₗ = -l, -l + 1, -l + 2, …., l

(mₛ is a quantum number for electrons)

Thus, we can have the following combinations.

$\begin{array}{ccr}\mathbf{n} & \mathbf{l} & \mathbf{m_{l}}\\5 & 2 & -2\\5 & 2 & -1\\5 & 2 & 0\\5 & 2 & 1\\5 & 2 & 2\\\end{array}$

That makes a total of five 5d orbitals.

The pictures below show what two of them look like.

Which of the following is a factor that determines the rate of impulse propagation, or conduction velocity, along an axon?a) len

Alexxx [7]

Answer:

c) degree of myelination of the axon

Explanation:

Axon conduction velocity can be defined as the speed at which an electrochemical impulse propagates down an axon.

Factors that determines the rate of conduction velocity are:

axon diameter-larger diameter axons have a higher conduction velocity
sheeth-a myelin sheath increases the rate of impulse propagatio

Different types of neurons will have different speed of propagation because of their different properties and because different types of information are sent.

: the pertussis toxin was found to interfere with the ligand-binding site in g-protein coupled receptors. at which point in the

Ronch [10]

The point at which the toxin would interrupt normal cell signalling in the pathway is the signal amplification.
This is because of the G-protein uncoupling and inhibition of signal amplification by pertusis toxin. Pertusis toxin released by the bacteria Bordetella pertusis and prevents signal that is amplifying from the protein. The G-protein coordinates the interaction between membrane bound receptor proteins and the effector proteins involved in the intracellular signalling. The toxin promotes the uncoupling of this heterotrimetric protein and also inhibits the amplification thus preventing the interaction of the receptor proteins and the second messengers.

In which structure would a zygote occur in within the female reproductive system

PSYCHO15rus [73]

Sexual fertilization takes place when a sperm from the male fuses into the egg cell of the female. Human cells contain 23 chromosomes and has a total of 46 pairs of chromosomes. A male has a total of 46 pairs chromosomes and gives 23 chromosomes while a female has a total of 46 pairs of chromosomes and gives 23 chromosomes to the offspring. These pairing are responsible to the trait of the offspring. The formation of both male and female gametes creates a zygote. They will start to form at the fallopian tube, down to the oviduct and into the uterus as it continues to divide.
