The right answer is compression.

There are basically two types of constraints that deform rocks: compression and tension constraints. In compression, forces converge; they can be coaxial or not.

The deformation of a card set under compression constraints illustrates the difference: In the case of a coaxial compression constraint, the cards will be arched. If the stresses are not coaxial, shear will develop; the card game is deformed by sliding the cards on top of each other:

klasskru [66]

Answer:

a. F1 genotype : IiBb F1 phenotype : Hairless

F2 genotype and phenotype :

I_B_ (hairless), iiB_ (straight), iibb (bent)

b. IiBb X iiBb

Explanation:

a. Fly 1 : pure breeding straight haired : iiBB

Fly 2 : pure breeding hairless with bent genotype : IIbb

Fly 1 X Fly 2 : iiBB X IIbb = IiBb (F1)

All the offspring will be hairless since there is one dominant I allele which will inhibit hair production regardless of the type of allele of other gene.

Two F1 flies will be crossed to obtain F2 flies. IiBb X IiBb :

I_B_ : hairless = 9

I_bb : hairless = 3

iiB_ : straight hair = 3

iibb : bent hair = 1

Hairless : straight : bent will be in 12 : 3 : 1 ratio.

b. The offspring of this cross :

hairless : I_ _ _

straight : iiB_

bent : iibb

There is a bent offspring which has both the recessive alleles of both the genes. Hence it must have obtained the two alleles from the two parents. So their genotype is _i_b and _i_b.

Half of the offspring are hairless as given by the ratio. This is only possible if the cross is between Ii and ii fly:

I i

i Ii ii

So the genotype is Ii_b and ii_b.

The remaining hairy flies are in 3:1 ratio of straight to bent. This is only possible if the cross is between Bb and Bb fly:

B b

B BB Bb

b Bb bb

So the final genotype of the flies is IiBb and iiBb.

A strawberry farmer finds that, after a hard freeze, some of his strawberries are still alive. Which best explains why these str

zhenek [66]

Answer:

B. They have different genetic variations that cause them to be more resistant

Explanation:

We do not know the phenotype of the strawberries and cannot tell if they have a darker color or larger leaves so that eliminates A. and D. We also do not know which strawberries produce faster or if the strawberries are even a different type than the ones the froze so that eliminates C. But what we do know is that variation is key to survival and variation means some organisms might not be able to resist certain things others can.
