Respond to the following based on your reading. The testes are male reproductive organs that produce and store , which is the male gamete containing half of the DNA in somatic cells. The typically 28-day process of egg release from the ovaries and, if fertilization does not occur, release from the body, is known as the cycle. If two eggs are released and fertilized by two different sperm, then twins will occur. If a hormone operates by entering a cell's nucleus and altering the expression of its DNA, then it is classified as a/n hormone. Once sperm cells are mixed with seminal fluid to provide protection and nutrition, this mixture is known as . The bulbourethral and glands play an important role in providing additional fluids to semen production. The first phases of a new zygote's growth through mitosis occur in the . The germ layer will eventually develop into the skin and nervous system. A fetus growing in the uterus does not eat food or drink water. Instead, important nutrients, antibodies, and molecules pass from the mother through the . Make a list, or write a short paragraph, that explains the major stages of pregnancy after fertilization, through childbirth. Provide as much detail as possible.

Why is excretion necessary to maintain homeostasis?

The accompanying figure shows the percent of selected dna sequences that match between a chimpanzee and other primates. these data support the hypothesis that the figure shows the percentage of selected d n a sequences that match between the chimpanzee and other primates. the human has an almost 98 percent match, the gorilla has an almost 97 percent match, the orangutan has a 96 percent match, the gibbon has an almost 95 percent match, and the old world monkey has an almost 92 percent match. the accompanying figure shows the percent of selected dna sequences that match between a chimpanzee and other primates. these data support the hypothesis that the figure shows the percentage of selected d n a sequences that match between the chimpanzee and other primates. the human has an almost 98 percent match, the gorilla has an almost 97 percent match, the orangutan has a 96 percent match, the gibbon has an almost 95 percent match, and the old world monkey has an almost 92 percent match. chimpanzees and gibbons are the most closely related the chimpanzee's closest surviving relative is humans orangutans are the primates least closely related to chimpanzees old world monkeys and gibbons are the most closely related

In 1959, doctors began using the powerful antibiotic methicillin to treat infections of staphylococcus aureus, but within two years, methicillin-resistant strains of s. aureus (mrsa) appeared. how did the resistant strains of s. aureus emerge? in 1959, doctors began using the powerful antibiotic methicillin to treat infections of staphylococcus aureus, but within two years, methicillin-resistant strains of s. aureus (mrsa) appeared. how did the resistant strains of s. aureus emerge? staphylococcus aureus bacteria that were able to synthesize cell walls using a protein that was not affected by methicillin survived the methicillin treatments and reproduced at higher rates than did other individuals. over time, these resistant individuals became increasingly common. in response to treatment of staphylococcus aureus infections with methicillin, some bacteria began to synthesize cell walls using a protein that was not affected by methicillin. these bacteria survived the methicillin treatments and reproduced at higher rates than did other individuals. over time, these resistant individuals became increasingly common. in response to treatment of staphylococcus aureus infections with methicillin, bacterial populations gradually began to synthesize cell walls using a protein that was not affected by methicillin.
