Hysterectomy Is a surgical removal ofthe Uterus.It may or may not be accompanied by Salpingo-oophorectomy, removal of the uterine tubes and ovaries. Why would it be an advantage to leave the ovaries intact
It is an advantage to leave the ovaries intact because the woman will still be able to produce eggs and children through In vitro fertilization.
What is an Ovary?This is a part of the female reproductive system which serves as the site for egg production.
When the ovaries are intact, the eggs can be taken and fertilized with the sperm in a lab dish and implanted into the uterus of another female for development of the zygote.

Answer: Stage 1 because, at stage 1 all embryos look similar but as they grow older they start look different depending on their genes
Question 2: Similarities in structure among distantly related species are analogous if they evolved independently in similar environments. They provide good evidence for natural selection. Examples of evidence from embryology which supports common ancestry include the tail and gill slits present in all early vertebrate embryos.
QUestion 3: Similar body parts may be homologous structures or analogous structures. Both provide evidence for evolution. Homologous structures are structures that are similar in related organisms because they were inherited from a common ancestor. These structures may or may not have the same function in the descendants.

Suppose oxygen was much less electronegative than it is, so that hydrogen-oxygen bonds were much less polar and hydrogen bonds could not form between water molecules. how would the properties of water most likely change? check all that apply. its boiling point would decrease. its melting point would increase. ice would sink in liquid water. water vapor would be denser than liquid water.
The properties of water that most likely change by the above inferences are:
Its boiling point would decrease.Its melting point would increase. Water vapor would be denser than liquid water. What do you mean by hydrogen bonds?Hydrogen bonds may be defined as interactions involving a hydrogen atom located between a pair of other atoms having a high affinity for electrons.
According to this hypothesis, the property of water may get deflected and new properties are assumed to a large extent.
Therefore, the above are the statements that best describe the properties of water that are altered.

what happens if too much water is reabsorbed into the blood from the material in the large intestine and the problems this can cause.
Answer:
More ADH will be released, which results in water being reabsorbed and small volume of concentrated urine will be produced. If a person has consumed a large volume of water and has not lost much water by sweating, then too much water might be detected in the blood plasma by the hypothalamus.
Explanation:
If too much water is reabsorbed into the blood from the material in the large intestine, it can lead to dehydration.
The large intestine is responsible for absorbing water and electrolytes from the indigestible material that remains after digestion in the small intestine. Under normal circumstances, the amount of water that is reabsorbed is carefully regulated to ensure that the body stays hydrated and that the consistency of the stool is appropriate.
However, if too much water is reabsorbed, it can lead to dehydration, which can cause a variety of symptoms and problems. These may include:
Dry mouth and thirstDark yellow urineDry skinHeadachesFatigueConstipationDizziness or lightheadednessIncreased heart rateDehydration can be caused by a variety of factors, including not drinking enough fluids, sweating excessively, or having diarrhea. It is important to drink enough fluids and replace lost electrolytes to prevent dehydration. In severe cases, dehydration may require medical treatment.

Explain how the sun’s gravitational pull extends to all 8 planets
Answer:
Gravity is the force by which a planet or other body draws objects toward its center. The force of gravity keeps all of the planets in orbit around the sun.
Explanation:
hope that helps
The sun’s gravitational pull extends to all 8 planets by the The Sun's gravity pulls the planets in orbit round it, and a few planets pull moons in orbit round them.
What causes the planets to have gravity?A planet's orbital pace changes, relying on how a long way it's far from the Sun. The nearer a planet is to the Sun, the more potent the Sun's gravitational pull on it, and the quicker the planet movements. The farther it's far from the Sun, the weaker the Sun's gravitational pull, and the slower it movements in its orbit.
Even spacecraft are in movement via the sun system, both in orbit across the Earth or Moon, or touring to similarly worlds, due to gravitational forces.

O Growing new trees to replace old trees
O Using metals mined from deeper rock sources
O Putting garbage on land instead of in the ocean
Switching to a new resource when another runs out
Answer:
Growing new trees to replace old trees
Explanation:
Growing new trees in place of old ones sustains the environment, since trees help circulate oxygen and provide homes and nutrients for animals and other plants.
Any form of mining is bad for the environment and unsustainable in the long run, garbage is the same way, and putting it on land is only slightly better, and switching to other resources doesn't do anything but burn out more resources and does nothing to sustain anything.
