ANEK [815]3 years ago

Answer:

D. all of the above

Explanation:

The water molecules have surrounded salt (NaCl) ions in the given diagram.

Salt get dissolve in water as both are polar, having positive and negative charges and both have electrical charges. Covalent bonds in water molecules are more stronger than the ionic bonds of salts, that is why salt dissolve in water.

Water molecules and salt molecules form electrostatic interaction in which the positively charges ends of water molecules are attracted to the negative chloride ions (Cl- ion) while negative ends of the water molecules are attracted to the positive sodium ion (Na+ ion).

Water molecule breaks the ionic bond between sodium and chloride ions. Water molecules form hydration shell around sodium (Na+) and calcium (Cl-) ions and allow the salt to dissolve in water and forma homogeneous solution.

Hence, the correct option is "D. All of the above".

How is a frog disected?
Stella [2.4K]
<span>Lay the frog on its back, spread out its limbs, and pin them to the tray. Use forceps to lift the skin between the hind legs and make a small incision with a scalpel. Continue the cut up the center of the frog's body with scissors, being careful to cut through the skin only. Use forceps to hold the skin away from the muscle while you cut, if necessary. Make horizontal incisions just above the legs and just below the arms, then fold the resulting flaps back and pin them. (You may need to use a scalpel to help separate the skin from the muscle underneath as you fold it back.)Repeat the incisions as before, this time cutting through the muscle layer to a point just below the arms. Lift the muscle with the forceps to prevent cutting the organs underneath.When you reach the area just below the arms, turn your scissors and make horizontal cuts through the hard sternum. Repeat the horizontal cuts just above the arms, and then remove the bony strips entirely. Pin the remaining muscle flaps back, just as with the skin.<span>Look into the body cavity. The yellow finger-like projections on the sides are the fat bodies. It may be necessary to remove some of these in order to see the organs clearly. Likewise, a female specimen may have well-developed eggs filling the body cavity and obscuring the organs. Remove them as necessary.</span></span>

What are some advantages and disadvantages of
andrew-mc [135]

Answer:Asexual Reproduction Sexual Reproduction

Advantages Time Efficient; no need to search for mate, requires less energy Variation, Unique., organism is more protected

Disadvantages No variation - if the parent has a genetic disease, offspring does too. Requires two organisms, requires more energy

Explanation:While asexual reproduction only involves one organism, sexual reproduction requires both a male and a female. Some plants and unicellular organisms reproduce asexually. Most mammals and fish use sexual reproduction. Some organisms like corals and komodo dragons can reproduce either sexually or asexually. But in the long term (over several generations), lack of sexual reproduction compromises their ability to adapt to the environment because they do not benefit from the genetic variation introduced by sexual reproduction

How is osteoporosis different from rickets
nasty-shy [4]

Rickets is a disease of growing bones. Consequently, it usually is seen in young, weaned, growing pigs in which there is a deficiency, an imbalance, or a failure of utilization of calcium, phosphorous or vitamin D. Rickets usually is caused by a dietary deficiency of vitamin D or phosphorus. And Osteoporosis a medical condition in which the bones become brittle and fragile from loss of tissue, typically as a result of hormonal changes, or deficiency of calcium or vitamin D. More than 10 million Americans have osteoporosis, but most do not realize that they have it.

One of the big differences is one occurs mostly to pigs and the other effects adults.Another difference is one occurs while the bones are growing and the other happens after the bones are already grown. I hope this helps!!!
