Answer:
The correct answer would be -
17. 50% chances of round offspring
18. 25% chances two copies of dominant allele in the genotype of offspring
Explanation:
17. In this question it is stated that the Spongebob is heterozygous and has a square body which means the square body is dominant over the round that is present in sponge Susie that means she has two copies of the recessive allele.
S for square trait and s for a round trait then
S s
s Ss ss
s Ss ss
Thus, the correct answer is 50 percent as there are only two copies of ss.
18. in this question Patric and Patti both have heterozygous for the pink (P) body-color dominant over yellow (p). The chances for the true-breeding dominant genotype would be -
P p
P PP Pp
p Pp pp
There is only one out of four rue-breeding dominant offspring will be produced.
Answer:
Explanation:
One of the properties of a liquid is that, <u>it's particles move freely (not tightly packed)</u> hence the reason for <u>it's free flowing (no definite shape)</u> when shaken in a container, unlike a solid whose <u>particles are tightly packed with restricted/no movement</u> and hence the reason for it's compactness and it's definite shape.
When a plastic solid (whose particle is tightly packed and have a restricted movement/no movement) is placed near a heat source, <u>it's particles gains energy in the process and starts to move (though slightly free) and become less tightly packed</u> hence the reason it is observed that plastic solids near a heat source melts.
From the above, it can be deduced that a liquid and a plastic solid near a heat source <u>have there particles move freely (and not tightly packed) hence making the two substances flow freely with no definite shape.</u>
Some things that can indicate a chemical change are change of odor, change of color, change in temperature or energy, such as the production or loss of heat. An example could be the rusting of metal, there would be a color change of going from a shiny silver to a dirty, splotchy red color. Some things that indicate a physical change are change of appearance like change of shape, etc. It can also be like a change between a solid to liquid to gas. For example, the cutting of a piece of paper.
I'm not completely sure but if I did know I would definitely tell u
