Answer:
heterozygous purple pea plant and heterozygous purple pea plant
Explanation:
Suppose the gene controlling flower colour in pea is P. Allele P is dominant over allele p. So, PP and Pp produce purple flowers and pp produces white flowers. If two heterozygous purple pea plants (Pp) are crossed :
Pp X Pp :
P p
P PP Pp
p Pp pp
As evident, the progeny will have genotypic ratio of 1 : 2 : 1 ( PP : Pp : pp ) and phenotypic ratio of 3 : 1 ( Purple : white )
Hence two heterozygous purple pea plants will produce 3:1 ratio of purple to white pea plants.

Answer: 3. Asking the client questions, using a postpartum depression scale.
Explanation:
The postpartum depression is the kind of depression phase which begins within 3-4 days after the delivery or completion of pregnancy. It actually required no treatment. It usually starts within the first month after childbirth and it may last to months.
The postpartum depression scale is a tool which can be used to identify whether the women is suffering from postpartum depression. It helps in assessing the client's emotional status. It includes a questionare which a women answers on the basis of which emotional state can be evaluated.
Answer:
1. Analogous
2. Homologous
Explanation:
The tentacles of an octopus and the limbs of a lizard perform the same function but have a different evolutionary lineage. Therefore, they are Analogous.
Analogous features/parts comparison are usually associated with the same functions but a different evolutionary lineage.
The front legs of a cat and the arms of a human share a bone structure that suggests a common evolutionary lineage. Therefore, these skeletal structures are homologous.
Homologous on the other hand involves having a common evolutionary lineage as a result of certain unique characteristics.
