Among a species of butterflies, the color blue (B) is a dominant trait. Yellow color (b) is a recessive trait. If a pure blue butterfly (BB) mates with a pure yellow (bb), what will the offspring look like?. A). They will all be blue..
B). They will all be yellow..
C). Half will be blue and half will be yellow..
D). About 75% will be blue and 25% will be yellow..

Answers

Answer 1
Answer:

Answer:

The correct answer would be A). They will all be blue.

Genotype of the parents are BB and bb.

As both are homozygous in nature so, each will produce only one type of gamete.

BB will produce gamete B and bb will produce b as its gamete.

The cross will results in the production of offspring each with genotype Bb.

We know that blue is a dominant trait and thus it will be expressed in heterozygous condition (Bb).

Hence, all offspring would be blue in color.

If a balloon filled with air and sealed is kept in a deep freezer for a period of time, it will shrink in size. Determine the the best reasoning for this outcome.

Answers

The temperature of the air in the balloon will decrease. The cold makes the molecules move slower and they get closer together. This leads to a lower pressure inside the balloon. The pressure on the outside is higher than the inside and it pushes the balloon to shrink.

CHOICES:

A) The air particles inside the balloon slow down due to lower thermal energy. As a result, fewer collisions take place per second and this leads to a lower pressure inside the balloon. The pressure on the outside of the balloon pushes the balloon to a smaller volume.  

B) The air particles inside the balloon slow down due to lower thermal energy. As a result, the air particles become charged, attract to each other and take up a smaller volume. Therefore, the balloon shrinks.  

Eliminate

C) The rubber latex of the balloon becomes colder and will resist stretching and push the air particles inward until the inside pressure equals the outside pressure and equilibrium is established.  

D) The density of the air particles increases within the balloon causing some particles to escape out of the balloon. This leads to an increase in the particles and, thus, pressure outside the balloon. This causes the balloon to collapse.

What is speciation? A.the process by which new species are formed

B.the mutations that take place in an organism’s DNA

C.the way that most species become extinct

D.the adaptations that help an organism fit into its environment

Answers

The answer is A. Speciation is the process by which new species are formed. It is an evolutionary process where certain biological populations evolve to new distinct species. It was the biologist Orator F. Cook who first coined this term. There are types of speciation namely sympatric, parapatric, peripatric and allopatric.
