C waning crescent and waxing crescent
Answer:
A woman is born with all of her eggs, which are stored in her ovaries. The ovaries also make the hormones estrogen and progesterone, which control her period (menstruation) and the release of eggs (ovulation). Menopause happens when the ovaries no longer release an egg every month and menstruation stops.
Sucrose: glucose + fructose sucrose is a disaccharide made from glucose and fructose
glucose: C(sub 6)H(sub 12)O(sub6)fructose: C(sub 6)H(sub 12)O(sub6)sucrose: C(sub 12)H(sub 22)O(sub 11)a water molecule, H(sub 2)O gets removed which is why there are 2 less hydrogens and one less oxygen
The right answer is: aorta to smaller systemic arteries to systemic capillaries to systemic veins to right atrium through the tricuspid valve.
The blood pathway is divided into two circuits, both beginning and ending in the heart.
- Systemic circulation (or general circulation, or "circulation")
It begins in the left ventricle, which through an artery distributes oxygenated blood to organs. Then the blood returns to the right heart (right atrium) through the cellar veins.
Each organ has an afferent vessel, supplying blood, and an efferent vessel carrying non-oxygenated blood.
- The pulmonary circulation (or "small circulation")
It begins in the right ventricle, from where the pulmonary artery sends blood without hematosis to a single organ, the lung. The blood is then oxygenated and returns to the left heart (left atrium) by the pulmonary veins.
Answer: In vitro fertilization
Explanation:
In vitro fertilization (IVF) involves some procedures used to help with fertility. This series of procedures are usually complex and can help prevent genetic problems and assist with the conception of a child.
During IVF, mature eggs are collected from the female ovaries and sperms from the male and fertilized in the laboratory. The fertilized egg are then transfered back into the uterus for its growth and development.
The sperm and eggs could be from partners who have decided to carry out IVF or from donors. IVF is usually Carried out by high rating laboratory. One full cycle of IVF takes about three weeks. IVF are usually expensive and could take a longer time if splits into different aspects.
IVF is an effective reproductive technology.
