Stimulus, because the ringing of the bell is something that might provoke a response.
Molodets [167]3 years ago
5 0

Answer:

The ringing of the bell was Introduced as a neutral 

stimulus by Pavlov. A stimulus which leads to an 

automatic response is an unconditioned stimulus. 

The food was the unconditioned trigger in Pavlov's 

experment. An automatic response to a stimulus is an  unconditioned response.

how does the second law of thermodynamics help explain the diffusion of a substance across a membrane?
Damm [24]

The second law is the trend toward randomization, or increasing entropy.  

Second law allows for diffusion because diffusion is an increase in entropy .Diffusion is the process of movement of molecule down the concentration gradient until they doesn't exist . This movement represents an increase in the entropy.

Second Law of Thermodynamics state that molecules will spontaneously move towards an area of lower concentration, from an area of higher concentration. Molecule are capable to travel across cell membranes known as lipophilic molecules as they dissolve in the lipid bilayer. Movement represents an increase in the entropy or disorder in the system .

Why does moving pollen from one pollen to another help the plants​
ahrayia [7]

Answer:

Flowers have male parts called stamens that produce a sticky powder called pollen. When pollen from a plant's stamen is transferred to a different plant's stigma, it is called cross-pollination. Cross-pollination produces stronger plants. The plants must be of the same species.

A primary transcript (immature, non-processed) single-stranded RNA molecule has the following nucleotide composition: 30% A, 20%
Viefleur [7K]

Answer: The nucleotide composition of the double-stranded DNA molecule from which it was transcribed is 30% T, 20% C, 24% G, and 26% A.

Explanation: RNA is transcribed from DNA in the process of transcription. The single stranded RNA is complementary to the DNA template strand. In DNA base pairing, adenine pairs with thymine while guanine pairs with cytosine, this means that in a double-stranded DNA molecule, the total number of adenine is equal to the number of thymine while the total number of guanine is equal to the total number of cytosine.

In RNA, adenine pairs with thymine, guanine pairs with cytosine while uracil pairs with adenine. This means that the total number of thymine on the DNA template strand is equal to the total number of adenine on the RNA strand, the total number of guanine on the DNA template strand is equal to the total number of cytosine on the RNA strand, the total number of adenine on the DNA template strand is equal to the total number of uracil on the RNA strand while the total number of cytosine on the DNA template strand is equal to the total number of guanine on the RNA strand.

RNA strand = DNA strand

30% A = 30% T

20% G = 20% C

24% C = 24% G

26% U = 26% A

How can a squirrel jump for a tall tree and reach the ground safely, while a human could easily break or bone
oee [108]

Answer:

<em>Their fluffy tails act as a parachute </em>

<em></em>

<em>And well, humans don't have fluffy tails-</em>

Explanation:

Technically a squirrel can fall any distance from a tree. However, the distance a squirrel can fall safely from a tree is about a hundred feet. That’s an incredible plummet for most creatures. Luckily, squirrels can use their fluffy tails like a parachute.

Hope it helps :)
