The first one with the boxing crab and anemone is mutualism.
The second one with the dog and flea is parasitism.
Because the three-horned alien is heterozygous, we know that three must be dominant to four, because the gene for the three horns is "hiding" the gene for four horns. Therefore, the three-horned alien has the genotype Tt (T for three horns, and t for four horns). The four horned alien must be tt, because that is the only way that a recessive trait may be seen. If you solve the punnet square on a cross between Tt and tt, you end up with half three (heterozygous) and half four (homozygous recessive) it is a bit easier to explain with something a little "closer to home" if you want me to explain it again, just say so, I don't mind!
Answer:
homologous chromosomes
Explanation:
Homologous chromosomes are the same length and have specific nucleotide segments called genes in exactly the same location, or locus.
28. Part A.
A nucleic has a sugar group, a phosphate group, and nitrogenous base. A carbohydrate only has the sugar group units.
Part B
Nucleic acids make up the DNA and RNA which contain the genetic material for life.
Carbohydrates are used to provide energy to the cells.
Part C
Because all life require energy and this energy can be obtained from carbohydrates.
31
Part A
The phenotype will be red flower.
Part B.
Using the Punnett Square, the results are
RR, Rr, Rr, rr
There are 3 red flower plant for every 1 white flower plant
Part C.
He should cross a wild or pure breed red flower and white flower snap dragons.
