Answer:

Gaseous atoms and plasmic ions

Explanation:

The atoms or ions in a solid state vibrate about their own fixed location upon heating. The atoms in solid state are tightly packed together and do not have space between them to expand in all direction. The atoms of liquid state are less tightly packed than that of the solid state but cannot expand in all directions due to their fixed volume. Ions/ atoms in gaseous and plasma state are present far apart from each other. These ions/atoms can move freely and expand in all directions since they are not held together with each other by interacting forces or bonds.

The answer would be (C.cat) because <span>For the cat has the most advanced biological system, whereas the unicellular algae and bacteria are microscopic in size, and while the ant does have a system and is a multi-cellular organism, the cat has a much more advanced biological system with many more functions and organs.

Hope it helps!

106US Gregor Mendel performed numerous dihybrid crosses between pea plants. Dihybrid

Ivanshal [37]

Answer: 25% of the offsprings will be heterozygous for both traits

Explanation: A cross between BbFf and bbff will yield 16 offsprings with four different possible genotypes: BbFf, Bbff, bbFf, and bbff. Only BbFf is the genotype that is heterozygous for both traits, and there are four offsprings with BbFf genotype.

Therefore the percentage of the offsprings that are heterozygous for both traits is 4/16 x 100 = 25%

See the punnett square for the details of the dibybrid cross
