Answer:
A few of the positive particles aimed at a gold foil seemed to bounce back.
Explanation:
Some of the positive particles aimed at a gold foil seemed to bounce back which gives information to the scientists that some heavy particles present in the center of the atom which bounce back the positive particles. so from this evidence the scientists says that atom is divisible and having subatomic particles such as proton, electron and neutron. Proton and neutron is present in the center whereas electron is revolving around the nucleus of an atom.
Answer:
Nucleus could I have brainliest sorry to bother.
Explanation:
The correct answer is 3. A, C and D
Square labels A, C and D are to be marked as "green pods."
According to Mendel’s laws of inheritance, when a plant with dominant trait is crossed with plant with recessive trait, as a result dominant phenotype is appeared in all the F1 offspring. On Selfing F1 offspring, produces F2 offspring with dominant and recessive trait. In the given scenario, pea plant with ‘green pods’ are dominant and pea plant with ‘yellow pods’ is recessive. Therefore, when pea plant with green pod is crossed with pea plant with yellow pods, the F1 offspring (C) produced are with green pods. Thus, parent (A) is with green pods and F2 offspring (D) is with green pods.
Answer:Each time two CF carriers have a child together, the chances are: 25 percent (1 in 4) the child will have CF. 50 percent (1 in 2) the child will be a carrier but will not have CF. 25 percent (1 in 4) the child will not be a carrier of the gene and will not have CF.
