Answer:
Answer is option B - "I should shower rather than take a tub bath."
Explanation:
Abdominal hysterectomy is the surgical removal of a part or all of the uterus by making an incision in the lower abdomen. After the surgery, the patient normally spends 2 - 5 days in the hospital and takes at least 4 - 6 weeks to get completely better. Some of the major discharge instructions are;
- Drink enough water and eat smaller meals that are rich in proteins and fiber and plenty of fruits and vegetables daily. This helps with the healing process and prevents constipation.
- Avoid swimming or taking a tub bath, but can take showers.
- Dressings over the incision should be removed daily and keep the wound area clean.
- Avoid inserting anything such as tampons into the vagina for 6 weeks after the surgery.
- Avoid all heavy activity including strenuous household activities, weightlifting, and other strenuous exercises. Short walking and light household chores can be done.
- Avoid driving if the patient is taking narcotic pain-relieving medicines. Long trips in vehicles or airplanes are not recommended for 4 weeks after the surgery.
Answer: When you mix sand and water there are no reactions. The sand sits at the bottom of the water because the sand is heavier than the water is.
Answer:
Meiosis produces four genetically different haploid cells.
Gametic chromosomes have a different combination of alleles than parental chromosomes as a result of independent assortment
Explanation:
Meiosis and Mitosis are two types of cell division that occurs in living organisms. However, Mitosis produces daughter cells that are genetically identical to the parent cell while meiosis produces daughter cells that are genetically different from the parent cell. This accounts for the reason meiosis leads to genetic variation.
The production of genetically different cells by meiosis is as a result of the process of the random orientation of chromosomes during metaphase I of meiosis I. This process is called INDEPENDENT ASSORTMENT. However, crossing over occurs during prophase I of meiosis between non-sister chromatids of homologous chromosomes.
Answer:
Until recently, most neuroscientists thought we were born with all the neurons we were ever going to have. As children we might produce some new neurons to help build the pathways - called neural circuits - that act as information highways between different areas of the brain. But scientists believed that once a neural circuit was in place, adding any new neurons would disrupt the flow of information and disable the brain’s communication system.
In 1962, scientist Joseph Altman challenged this belief when he saw evidence of neurogenesis (the birth of neurons) in a region of the adult rat brain called the hippocampus. He later reported that newborn neurons migrated from their birthplace in the hippocampus to other parts of the brain. In 1979, another scientist, Michael Kaplan, confirmed Altman’s findings in the rat brain, and in 1983 he found neural precursor cells in the forebrain of an adult monkey.
These discoveries about neurogenesis in the adult brain were surprising to other researchers who didn’t think they could be true in humans. But in the early 1980s, a scientist trying to understand how birds learn to sing suggested that neuroscientists look again at neurogenesis in the adult brain and begin to see how it might make sense. In a series of experiments, Fernando Nottebohm and his research team showed that the numbers of neurons in the forebrains of male canaries dramatically increased during the mating season. This was the same time in which the birds had to learn new songs to attract females.
Why did these bird brains add neurons at such a critical time in learning? Nottebohm believed it was because fresh neurons helped store new song patterns within the neural circuits of the forebrain, the area of the brain that controls complex behaviors. These new neurons made learning possible. If birds made new neurons to help them remember and learn, Nottebohm thought the brains of mammals might too.
Other scientists believed these findings could not apply to mammals, but Elizabeth Gould later found evidence of newborn neurons in a distinct area of the brain in monkeys, and Fred Gage and Peter Eriksson showed that the adult human brain produced new neurons in a similar area.
For some neuroscientists, neurogenesis in the adult brain is still an unproven theory. But others think the evidence offers intriguing possibilities about the role of adult-generated neurons in learning and memory.
