False

In case of all polar molecule the amount of inter molecular forces (such as cohesion, adhesion etc.) is much smaller than intramolecular forces (such as dipole –dipole interactions, Hydrogen bonding etc.)

Due to this reason a polar molecule form a dipole –dipole structure due to which the charges are unevenly distributed on different parts of neutral molecule. The electrons are more strongly oriented towards oxygen atom and thus it gets negatively charged and hydrogen gets positively charged. A polar molecule attract another polar molecule either through Hydrogen bonding or through dipolar attraction between them.

For example dissolution of HCl in water is a polar -polar molecule interaction.

Explain how cell division allows changes in the DNA of a zygote to be inherited by future generations

Katarina [22]

Answer:

Explanation:

When cell divides, the DNA will replicate in the parent cell or make copies of itself and this will make the chromatics to split or divide in order to create a new cell or daughter cell which contain the exact same DNA. The daughter cell then pass these DNA to subsequent generations, when it also undergo cell division and the dna is been replicated

I’m having trouble understanding this can someone plz explain?

Answer:

look at the pictures

Explanation:

1. If we cross the parental generation which is RR x rr, the probability of the F1 generation to get rough coat is 100% and they will be a carrier of the recessive trait smooth coat.

Since the phenotypic ratio is 100% heterozygous Rr, in crossing the F1 to get the F2, we will use the genotype Rr. To get the F2, use the cross Rr x Rr.

The phenotypic ration for F2 is 3:1. There is 75% to get rough coat and 25% smooth. The answer is based on the result on the Punnett square. On the other hand, the genotypic ratio is 1:2:1. There is 25% probability to get RR genotype, 50% Rr, and 25% rr.

2. Since the two parental mice got 6 albino offspring and 5 brown mice offspring, it is approximately 50%. it takes a parental mice who is Brown that is carrying an albino trait crossed with an albino to get offspring with almost the same number. Therefore, the genotype of the brown mice is Aa.

Sergio039 [100]

Answer:

Cloning may be defined as the process by which the genetically identified individual of the organism can be created artifically or naturally. Aseual reproduction results in the formation of clone.

The microsatellite analysis is used to prove that snuppy is a clone. Microsatellites are the highly variable DNA sequences repeats that has variable loci and considered at population level. The two alleles are possible for the one microsatellite locus. After comparing the alleles it has been found that snuppy has exactly the same genetic material as the surrogate mother, afghan. This completely determines that snuppy is a clone of afgan.
