Answer:
<em>P p</em>
<em>P</em> PP Pp
<em>p </em>Pp pp
PP=Homozygous purple
Pp= heterozygous purple
pp=homozygous White
Explanation:
I tried to type out the cross. The bold letters are the heterozygous plants that you are crossing. and the normal letters are the offspring of the two heterozygous parents being crossed. Heterozygous means they are different alleles. Homosygous means the same alleles are present.
heterozygous= Pp
Homozygous= PP or pp

Answer:
B. Puerperium, or fourth trimester of pregnancy
Explanation:
- Puerperium or the fourth trimester of pregnancy is also known as the postpartum period.
- This period starts immediately after the mother gives birth to a child.
- During this period the size of the uterus and other reproductive organs along with the hormone levels return to their normal state.
- It is the phase where regression of all the anatomical and physiological changes that took place i in the reproductive organs of the females takes place.
- This phase is divided int three periods -
1. Immediate puerperium, or the first 24 hours after parturition
2. Early puerperium, which extends until the first week postpartum;
3. Remote puerperium, which includes the period required for involution of the genital organs and return of menses, usually approximately 6 weeks.
- This phase is highly critical for the mother as this requires rest and proper care as there are risks of bleeding. Therefore, the midwife or the nurse must take proper care of the mother.
Answer:
The correct answer is A) Histone deacetylation generally decreases gene expression.
Explanation:
Histones are the proteins that are responsible for the condensation of chromatin, which is directly linked to the capacity that a gene has to be expressed. The more condensed a gene is, the less expressible it becomes.
In order to regulate the gene expression, histones can suffer from many modifications that can change their conformation and the expressiveness of specific genes.
<u>Histone acetylation is linked with an increase of gene expression; while deacetylation and methylation decrease gene expression.</u>
