Describe the forms that water takes through out the water cycle
Aleks [24]

Gas: when the water has evaporated and is now out in the air. Water molecules move super fast during this stage.

Liquid: Water molecules have a good amount of space to move around, but they aren’t traveling as fast as they do in the gastric state.

Solid: ice in other words, the water molecules are super tight and compact, but are still moving around, just not very fast.

You perform the following dihybrid cross: A blaBx Ab/aB. The A and B genes control different traits. What phenotypic ratio would
Luda [366]

Answer:

Option-D

Explanation:

In the given question the genotype of parental allele is- AbaB X AbaB. The alleles formed will be- AB, Ab,aB, ab in which the crossover allele will be AB and ab.

1. Unlinked genes

Now of these alleles are unlinked then the alleles will assort independently of each other therefore performing the punnett square we will get dihybrid ratio as 9:3:3:1 in which  

1. A_B_ are 9

2. aaB_ are 3

3. A_bb are-3

4. aabb- 1

Since the crossover allele are AB and ab therefore A_B_ are 9 and aabb- 1 represent recombinant genotype.

2. Linked genes

When the genes will be linked then chances of crossing over will be reduced as a result of which only two type of allele will be formed which are-  Ab and aB and the recombinant frequency will become less.

Crossing these allele will  form Aabb , AaBb , AaBb  and aaBB  genotypes. The recombinant ratio will decrease as A_B_ is 2 and aabb is not present.

Thus, option-4 which states that the unlinked ration is  9:3:3:1  and linked ratio is  <9: >3: >3: <1 is correct.

Which three statements about electromagnetic radiation are true?
TEA [102]
Light is a form of EM radiation.
EM radiation has no mass (it's just energy packets called photons).
EM radiation can travel through a vacuum. (The speed of light in a vacuum is called c and is around 300,000 m/s).

Hope this helps!
