Puberty in boyâ€™s principal signs of puberty and hormonal control
Puberty varies on the child. It usually starts in boys at an age between 10 to 12 years old and usually last until the first time of ejaculating and seeing visible sperm, usually around 14 years old (Saladin, 2021). One of the main traits that happens in puberty is the testosterone rises. The first visible sign that occurs is an enlargement of the testes and scrotum (Saladin, 2021). Testosterone also stimulates a burst to the bones causing the boys bones to grow, more muscle mass, and deepening the voice (Saladin, 2021). DHT (dihydrotestosterone) gives boys things such as pubic hair, axillary hair, and finally facial hair (Saladin, 2021). Â Boys secrete a lot of amounts of testosterone in the first 3 months of fetal development (Saladin, 2021). A boy in the first few months of infancy has almost the same amount of testosterone levels as a boy in mid puberty but then the testes stop producing the testosterone in early childhood (Saladin, 2021). Â Why does the testosterone dissipate from early childhood till puberty? The gonadotropin realizing hormone or (GnRH) takes a break in a boyâ€™s youth. When in late childhood the GnRH comes back. GnRH then travels to places like the anterior pituitary and stimulates the cells called gonadotropic cells (Saladin, 2021). The cells then secrete two pituitary gonadotropins which are follicle stimulating hormone (FSH) and luteinizing hormone (LH) (Saladin, 2021).
As a boy your ready for puberty when it comes (as much as you can be). Among other things your ready to be able to grow facial hair. One thing youâ€™re not ready for is the acne that come with it. The DHT level are extremely high during this time sometimes up to 20 times the normal level also The skin becomes darker and thicker which leads to that acne (Saladin, 2021). It can be very tough to go through puberty with everything changing from the way you feel to how you look.

The benefits of breast-feeding: Â Including lactation reflex; describe the mechanism of milk ejection, shifting hormonal balanceÂ
Â Â Â Based on my research, there are many benefits that breast-feeding provides for both moms and babies such as boosting the babyâ€™s immune system, help lower the chance for moms to get breast and ovaries cancer and it is easier for baby to digest faster (5 Benefits of Breastfeeding, 2017). The milk that mothers produced and feed their babies is called lactation, which can last for many years as the mother continues to nurse their baby (Saladin, 2020, p. 1066). Milk ejection happens when the babies are sucking on the mother nipples and areola to stimulate the nerve in the mother’s body to release oxytocin (Saladin, 2020, p. 1067). After birth, mothers will experience hormones changes throughout their body which can lead to postpartum depression (Postpartum hormonal changes & how they affect you, 2019). One of the hormonal changes that can cause mothers to be moodier is prolactin because it affects the dopamine in the body (Postpartum hormonal changes & how they affect you, 2019). To furthermore, progesterone hormones also changes after birth compared to during pregnancy because it decreases which can makes the menstrual cycle becomes abnormal (Postpartum hormonal changes & how they affect you, 2019).Â
Â Â Â Â Based on my personal experience and research, I agree with breast-feeding your baby even if it is for the first 6 months. As you all know, I am a first-time mother, and unfortunately, I was able to see the differences from breast-feeding my baby to using formula. Breast-feeding is healthier for babies but not every mother can provide that for their babies for a long time. For the mothers that can breastfeed, it can be beneficial for the mothers because it can help them to lose the pregnancy weight faster and prevent them from the risk of breast cancer or ovary cancer. I can also say that the hormones from pregnancy and postpartum felt different for me because during my pregnancy I had more energy even in my third trimester, but I notice for my postpartum I wanted to rest more, I was more fatigue and mood swings got worst. Everyone’s experience might be different from others based on their surrounding and situation, but I will always be fascinated on how females’ body can produce nutrition for our babies until they are old enough to get it themselves.

Example Peer Response
When we consider this topic of DNA replication, we should first take a step back and consider
the function of the nucleus of the cell. The nucleus, a cellular organelle, contains the cellâ€™s
genetic information. The nucleus is centrally located within the cell. The nucleus is responsible
for directing the cellular activity of the cell. This function includes synthesizing new molecules
such as proteins and nucleic acids. It is the deoxyribonucleic acid (DNA) within the nucleus that
regulates protein synthesis. Some DNA can also be found within the mitochondria. This is a
good place to point out that all cells will have a nucleus at some point in their lifetime, but not
their entire lives. Do red blood cells have a nucleus? No. A red blood cells (RBCs) are also
known as erythrocytes. RBCs do not replicate during their lifetime, so there is no need for a
nucleus as the cell is recycled as it reaches the end of its lifespan, which is approximately 120
days (Seeley et al., 2014).
We must consider the amount of time it takes for the cell cycle to occur. How long does this
actually take? There is an interphase and the mitotic phase. The interphase accounts for most of
the time in the cell cycle, while the mitotic, or M-phase, is the last step in the process. The M-
phase may be the most important last step when the cell divides to create two daughter cells.
Here is a video on DNA replication that I used to study. I hope it helps you. It shows how both
strands of the DNA helix are unzipped and copied to produce two identical DNA molecules.
I went to this website and found so many more DNA videos! Hereâ€™s a question: Okazaki
fragments, what are these?
