Salts are crystalline and ionic in nature.
Crystalline is the property of solid substances in which the components or the molecules of the the solid substances are arranges in highly ordered manner. The appearance of such substances is crystal-like. These substances have sharp melting points.
Ionic nature of substances refers to the presence of ions in any substance. The ionic substances may have a positive charge or a negative charge or they may be neutral. Ionic substances have the tendency to either gain or lose electrons. When it gains electrons it becomes negative and when it loses electrons it becomes positive. Ionic substances are good conductors of electricity.

What interesting new hypothesis is being studied regarding embryo self-inspection
early in development?
The hypothesis was regarding embryo self-inspection in early development is that viability of embryo metabolism is quite rather than active due to depletion and appearance of amino acids from culture medium.
Early embryo consist of remarkable plasticity which means ability of separated early blastomeres to produce a whole organism. This aspect was determined from flux of radiolabeled methionine, premises that extent of DNA damage, RNA and protein content of immature oocyte are key factors whether zygote progresses to blastocyst stage.
This hypothesis was obtained from human and mouse and could be equally applied to reproduction in livestock, to get models for humans.

If a forecast states that the dew point and air temperatures are equal, what is likely to happen?
If a forecast states that the dew point and air temperatures are equal, the air is said to be saturated.
What is dew point?The dew point is the temperature to which a parcel of moist air must be cooled at constant atmospheric pressure and constant water vapor content in order for saturation to occur.
The dew point can also said to be the temperature at which the actual pressure of the vapor contained in an air parcel equals the saturation pressure, under constant atmospheric pressure.
When the dew point is equals the air temperature, the air is saturated and the relative humidity is %100.

Which means of particle transpoWhich means of particle transport requires input of energy from the cell?rt requires input of energy from the cell?
Active transport is the form of particle transport that requires input of energy from the cell.
Active transport is the one that makes use of energy for the transport of molecules across the membrane. It is further classified into two types: primary active transport and secondary active transport. Primary active transport directly uses the energy from ATP hydrolysis for the transport. Whereas, secondary transport involves cotransport system where the energy released from the downhill transport is used for the uphill transport of molecule.
Cell is the fundamental unit of life. It is the structural unit of all the organism. Cell can either be prokaryotic or eukaryotic.

Answer:
B.
Explanation:
Interdependent relationships in biology are based on mutual dependence between organs and body systems. Most organs have a job (aside from the appendix and such) and they all work together to keep the body running. For example, the lungs introduce air into the bloodstream, but what would be the point if there was no heart to pump the blood? Your organs fully depend in eachother to be effective.

Everywhere you look, you can find bacterium (plural: bacterium), which are typically free-living organisms made up of just one biological cell. They make up a sizable group of prokaryotic bacteria. Bacteria, which are among the earliest life forms to exist on Earth and are typically a few micrometers in length, are found in most of its environments. The deep biosphere of the Earth's crust, acidic hot springs, radioactive waste, and soil all support bacterial life. By recycling nutrients, such as fixing nitrogen from the atmosphere, bacteria play an important role in many stages of the nutrition cycle. The decomposition of dead bodies is a part of the nutrition cycle, and the putrefaction stage is brought on by bacteria. Extremophile bacteria offer the nutrients required to maintain life in the biological communities surrounding hydrothermal vents and cold seeps.

When the Carbon dioxide changes its state from gas to solid directly that is called dry ice.
How might dry ice be used for cleaning?Similar to sand blasting, dry ice cleaning, commonly referred to as cryogenic cleaning, uses solid CO2 or dry ice pellets instead of sand. The pellets expand by a factor of 700 when they hit the ground and evaporate into carbon dioxide gas. This expansion causes the contaminant to be raised and separated from the basic substance. creates daily dry ice blasting tools and exports them to numerous nations across the world.
In order to create dry ice, gaseous CO2 is first compressed and rapidly cooled to create liquid CO2. The liquid is next allowed to expand at a lower pressure to create CO2 snow. Finally, a hydraulic press compresses this snow into usable Dry Ice blocks, slices, or pellets.

Scientific researchers discovered agents that behaved like bacteria causing diseases such as rabies and hoof-and-mouth, but were much smaller. At this time it became the general view that viruses were biologically "alive." This changed in 1935 when the tobacco mosaic virus was crystallized and scientists demonstrated that the particles lacked any mechanisms necessary for metabolic function. It was determined that viruses consisted of a nucleic acid, DNA or RNA, surrounded by a protein shell and the scientific view changed: viruses are complex biochemical mechanisms but not alive. When not in contact with a host, the virus remains dormant. During this time there are no biological activities occurring and the virus is nothing more than a static organic particle. In this state viruses can remain for extended periods of time, waiting to come into contact with the appropriate host. When in contact with a host, it becomes active, reacts to its environment and/or host and directs its efforts toward self-replication. The viral goal now is to produce more viruses to attack host cells.

Explain what happens as your cell needs to divide. Include why your cell is dividing and the process of division
Answer:
Cells need to divide for your body to grow and for body tissue such as skin to continuously renew itself. When a cell divides, the outer membrane increasingly pinches inward until the new cells that are forming separate from each other. This process typically produces two new (daughter) cells from one (parent) cell
Explanation:
Why Cells Divide• Mitosis - the process your body cells use to make exact replicas of themselves.
• Meiosis - creates sperm or egg cells.
