<span>These quartz grains are indicative of sand being transported by wind. Climate will determine when and what type of quartz grains are found and what mode of transportation is used to relocate those quartz grains. Wind is a mode of transportation that is usually found in drier climates, such as the desert.</span>

I disagree with this statement. Asexual organisms are at a lower risk for extinction due to the fact that they do not need a partner to procreate. They have an easier time making offspring.

AVprozaik [17]

Answer:

In Labrador dogs, black coat is dominant to chocolate, normal vision is dominant to progressive retinal atrophy (PRA), and normal hip joint is dominant to hip dysplasia. All these genes assort independently. Two dogs that are heterozygous for alleles of all three genes are crossed. Using rules of probability (not a Punnett square), what is the chance that the first pup born to these dogs will be chocolate, have normal vision, and have normal hip joints?

BbVvHh x BbVvHh= BBVVHH, BbVvHh, BbVvHh, bbvvhh

Bb= black coat dominant

Vv= Normal vision dominant

Hh= Normal hip join dominant

probability of having a first born of these dogs will be chocolate, have normal vision and have normal hip joint is 0

Explanation:

As the punette square gives 3:1 phenotype having three black coat, normal vision and normal hip joint and one chocolate, progressive retina altropy and hip dysplasia

Enter your answer in the provided box. what is the value of ni for an electron that emits a photon of wavelength 95.04 nm when i
Sloan [31]
<span>Ni = 5 The Rydberg formula for hydrogen is 1/w = R(1/a^2 - 1/b^2) where w = wavelength in vacuum R = Rydberg constant 1.0973731568508x10^7 1/m a,b = integers greater than or equal to 1 and a < b Now we need to select the value for a. a = 1 will converge towards 91.13 nm a = 2 converges towards 364.51 nm a = 3 converges towards 820.14 nm ... Because of this, we will assume a = 1 for this problem since it converges closest to the wavelength given. Substitute known values 1/w = R(1/a^2 - 1/b^2) 1/9.504x10^-8 = 1.0973731568508x10^7(1/1^2 - 1/b^2) 10521885.52 = 1.0973731568508x10^7(1/1 - 1/b^2) 0.958824759 = 1 - 1/b^2 -0.041175241 = -1/b^2 0.041175241 = 1/b^2 24.28643927 = b^2 4.928127359 = b So Ni = 5.</span>

An animal cell with a 30% salt solution is placed in a beaker with a 20% salt
AleksAgata [21]

Answer:

the animal cell will burst

Explanation:

If the salt solution in the animal cell is 30%, it means the water is at a 70% concentration. Outside is 20%, so the water is 80%.

Water will enter the cell. Water is at a higher concentration outside the cell (80%) or a lower concentration inside the cell (70%) by the process of osmosis.

Eventually, the animal cell will burst, because it does not have any cell wall to control the swelling of the cell that occurs as water flows in.
