I believe it’s the metaphase
Answer:
We mean that a cell changes to another type of cell.
Explanation:
<em>Stem cells </em>are a type of cell that has the potential to become a specialized cell, this change or differentiation, is possible thanks to the activation or deactivation of certain genes that promote (or inhibit) the expression of certain proteins that origins different types of cells (fmuscle cells, osteocytes, neurons). This differentiation happens when the cells receive cues internally ( through signals or contact between a group of cells and another or through transcription factors) or externally.
Then, a differentiated cell is a cell that had gone under the previously described process.
I hope this information is useful to you!
Answer:
The phenotypes are as follows
Purple, full- 9
Purple, constricted- 3
White, full- 3
White, constricted- 1
Genotype of parents are PpFf, each produce the following gametes: PF, Pf, pF and pf.
Explanation:
This is a dihybrid cross involving two distinct genes. One coding for flower color and the other for pod shape. The allele for purple color (P) is dominant over the allele for white color (p) while the allele for full pod (F) is dominant over the allele for constricted pod (f).
In a cross between two heterozygote parents i.e. PpFf × PpFf, each parent will produce the following gametes: PF, Pf, pF and pf. Using these gametes in a punnet square (see attached image) the following 16 offsprings will be produced in a phenotypic ratio: 9:3:3:1
Purple color, full pod- 9
Purple color, constricted pod- 3
White flower, full pod- 3
White flower, constricted pod- 1
The correct answer is B. Contact comfort
Explanation:
Studies with Rhesus monkeys were carried out by the psychologists Harry Harlow to study psychological and emotional aspects related to maternal separation and isolation. In this experiment, Harlow used baby monkeys and observed their behavior in different situations that included separating the baby and the mother, providing a fake mother, isolating baby monkeys for a long time and allowing baby monkeys to choose between their mother or food. The results of this experiment showed mother-infant emotional bonds were key for the development and socialization of monkeys, this could be explained as mother monkeys provided contact comfort which supported a positive development and prevailed over food or nourishment.
