Answer:

An unconditioned response.

Explanation:

Pavlov was the process of studying salivation in dogs as a part of a research program on chewing and digestion. This is known as a normal reflex that is under personal choice or control and also called an unlearned evolutionary response.

In terms of Pavlov's analysis of learning, Pavlov built a device that would help to accurately measure the amount of saliva produced by dogs. In the case of Pavlov dogs, the food is called as the stimulus and salivation is called as a response.

A complete circuit contains two parallel-connected devices and a generator for providing the electromotive force. The resistance
mrs_skeptik [129]
Parallel circuits are circuits when placed in a parallel position. Meaning that for each device, they have their own branch. The voltage that is received in the circuit is equal to the individual devices. The total current is equal to the current of each device. The resistance is the reciprocal of the resistances of each device combined.  

Given:
Device 1 = 12 ohms
Device 2 = 4 ohms
Voltage total = 40V  

Required:
Current at 12 ohms  

Solution:
40V = V1 =V2  

Since V =IR
I1 = V1/R1
I1 = (40V)/(12 ohms)
<span><u>I1 = 3.334 A(Amperes)</u></span>

Airida [17]
<h2>Axons </h2>

Explanation:

Axons cross from one side of the spinal cord to the other through the gray commisure

  • Each arm or extension of the gray matter in the spinal cord is referred to as a horn
  • Projecting towards the back of the spinal cord are the dorsal horns (or posterior horns)
  • Projecting towards the front are the ventral horns (or anterior horns)
  • In the thoracic and upper lumbar regions of the cord, an additional pair of side projections occur, which are called the lateral horns
  • A narrow band of gray matter known as the gray commissure stretches across of the center of the spinal cord and connects the two sets of horns
  • In the middle of the gray commissure is the central canal, which contains cerebral spinal fluid

Allushta [10]

Answer:

The solute is powdered drink mix

Explanation:

The solute is powdered drink mix is solute because solute is any substance that dissolves in a solvent while solvent is the substance that dissolve solute or the dissolving medium. When solute dissolve in solvent it is called solution.

Solution is an homogeneous mixture of substance which comprises of solute that dissolve in solvent.

Anuta_ua [19.1K]

The question is incomplete. Here is the complete question.

In horses, the Overo gene, <em>Ov</em>, produces a white splotch pattern on the coat. The overo phenotype is seen only when a horse has one Ov copy, <em>Ovov</em>. Horses with two <em>Ov</em> copies, <em>OvOv</em>, die soon after birth are called white overo because they are completely white. Horses with no <em>Ov </em>copies are solid colored, <em>ovov</em>.

The Leopard complex gene, <em>Lp</em>, shows incomplete dominance and controls white spotting. One <em>Lp </em>allele, <em>Lplp</em>, produces the leopard phenotype, in which there are spots everywhere. Two <em>Lp</em> alleles, <em>LpLp</em>, produce the fewspot phenotype, in which the horse is mostly white with colored spots.

A horse that is both overo and leopard is called pintaloosa, and these horses are spotted with splotches. A horse that is overo and fewspot is considered fewspot because the white areas from <em>Lp</em> is indistinguishable from the white from <em>Ov</em>.

Suppose that 16 pairs of pintaloosa horses have one offpring per pair. How many each phenotype would be expected? Determine the number out of 16 expected for each phenotype. Only count phenotypes of offspring expected to live past one week of age.

overo:

white overo:

fewspot:

Answer: Overo: 2

              White overo: 0

              Fewspot: 3

Explanation: Pintaloosa is a "combination" of overo and leopard, so the pair's genotype is OvovLplp.

To cross a pair, use Punnet Square and to facilitate, use the square for each characteristics:

Punnett Square For overo and white overo:

          Ov             ov

Ov    OvOv        Ovov

ov    Ovov          ovov

Analysing this Punnett square, notice that there are 2 individuals who will carry the genotype for overo (Ovov) phenotype. So, 2 out of the 16 pair will have an overo phenotype.

Since white overo is recessive (ovov) and doesn't survive past birth, there will be zero horses with that phenotype.

Punnett Square For leopard and fewspot:

          Lp         lp

Lp    LpLp      Lplp

lp     Lplp       lplp

From this square, notice that there are 1 individual who is fewspot. However, a horse that is overo <u>and</u> fewspot is considered fewspot, so for the 16 pair, 3 out 16 will be fewspot.
