Mess up my notes part 2 00:01:40And the white snapdragon will have the genotype small r and small r. Now, when the alleles combi

ne, the result is always big R and small r. So, in incomplete dominance red and white are neither dominant nor recessive. So instead, both alleles are present in the offspring, resulting in pink snapdragons.
00:02:19 So I'm going to write big R and small r. Again, you see a blending of the colors. Red plus white makes pink.
Section 4
00:00:00TEACHER: Now, let's look at another way trait involving one gene with two alleles that are inherited. Codominance is an inheritance pattern in which the alleles are neither recessive nor dominant, and both alleles are expressed in the offspring. So, an example of this inheritance pattern can be observed when a black rooster here, on the left oh,
00:00:26there goes my neighbor's rooster, is crossed with a white hen, which is in the middle. And the offspring is a chicken that has black and white feathers. That can be very annoying in the morning time. This type is what is called a speckled chicken. The speckled chicken has both white feathers from her mom and black feathers from her dad.
00:00:53Both feather colors are dominant and codominant. Now let's use a Punnett Square to show codominance. Suppose a plant with purple flowers, as you can see here, is crossed with a plant that has white flowers. The allele that produces purple flowers is capital F superscript p, so we're just going to call it Fp. And the allele that produces white flowers is capital F and superscript w, so we'll just call it Fw.
00:01:30Now notice that for both alleles, the capital F represents the allele, and the super scripts represent the colors. If we combine the alleles of the parents right here, well, what do we get? We get these genotypes, Fp and Fw. Notice that all offspring have the same genotype Fp and Fw.
00:02:05Because purple and white are neither dominant nor recessive, the offspring shows both colors, purple and white, are observed. So therefore, you get Fp and Fw. In other words, both alleles are dominant or codominant.

Earth turns on its axis about once every 24 hours. The Earth's equatorial radius is 6.38 x 106 m. If some catastrophe caused Ear
san4es73 [151]

To solve this problem it is necessary to apply the concepts related to the Period of a body and the relationship between angular velocity and linear velocity.

The angular velocity as a function of the period is described as

\omega = \frac{2\pi}{T}

Where,

\omega =Angular velocity

T = Period

At the same time the relationship between Angular velocity and linear velocity is described by the equation.

v = \omega r

Where,

r = Radius

Our values are given as,

T = 24 hours

T = 24hours (\frac{3600s}{1 hour})

T = 86400s

We also know that the radius of the earth (r) is approximately

6.38*10^6m

Usando la ecuación de la velocidad angular entonces tenemos que

\omega = \frac{2\pi}{T}

\omega = \frac{2\pi}{86400}

\omega = 7.272*10^{-5}rad/s

Then the linear velocity would be,

v = \omega *r

xv = \omega *r

v= 463.96m/s

The speed would Earth's inhabitants who live at the equator go flying off Earth's surface is  463.96

What is a key difference between cell signaling by a cell-surface receptor and cell signaling by an intracellular receptor?
Art [367]

CORRECT ANSWER:

a- Cell-surface receptors bind polar signaling molecules; intracellular receptors bind nonpolar signaling molecules.

STEP-BY-STEP EXPLANATION:

The complete question from book is

According to Figure 9.6, what is a key difference between cell signaling by a cell-surface receptor and cell signaling by an intracellular receptor?

a- Cell-surface receptors bind polar signaling molecules; intracellular receptors bind nonpolar signaling molecules.

b- Signaling molecules that bind to cell-surface receptors lead to cellular responses restricted to the cytoplasm; signaling molecules that bind to intracellular receptors lead to cellular responses restricted to the nucleus.

c- Cell-surface receptors bind to specific signaling molecules; intracellular receptors bind any signaling molecule.

d- Cell-surface receptors typically bind to signaling molecules that are smaller than those bound by intracellular receptors.

e- None of the other answer options is correct.

A gas undergoes two processes. In the first, the volume remains constant at 0.200 m3 and the pressure increases from 1.00×105 Pa
Alborosie
<h2>The work done = - 2 x 10⁴ J</h2>

Explanation:

In the first case , the volume is kept constant and pressure varies .

In isothermal process  , the work done

W₁ = V x ΔP

here V is the volume of gas and ΔP is the change in pressure

Thus W₁ = 0

Because there is no change in volume , therefore displacement is zero .

In second case pressure is constant , but volume changes

Thus W₂ = P x ΔV

here P is the pressure  and ΔV is the change in volume

Therefore W₂ = 4 x 10⁵ x 5 x 10⁻² = 2 x 10⁴ J

The total work done W = - 2 x 10⁴ J

Because the work done in compression is negative .
