Answer:
If Red blood cell is placed in a hypotonic solution, the water moves into the cell. The cell swells and become turgid.
Explanation:
This is a type of osmosis. here plasma membrane of RBC works as semipermeable(only solute can move) osmotic membrane.
We all know that, osmosis is a process where liquid moves across semipermeable membrane from less concentration gradient to high concentration gradient.
There are three types of solution in respect of the concentration of cell's cytoplasm. These are
- Hypotionic (when the solution is dilute than the conc. of cytoplasm). In this condition water moves into the cell and the cell become turgid. this is known as deplasmolysis
- Hypertonic ( when the solution is concentrated than cytoplasm), In this condition water moves out from the cell and the cell become flaccid. This is known as plasmolysis.
- Isotonic (when both the conc. of cell and solution are same). No osmosis takes place.
Answer:
Genetic Engineering
Explanation:
Image result for Two tomato plants are cross pollinated to produce tomato plants that produce more tomatoes.
When tomatoes cross pollinate, the genetic material of the two tomato varieties will combine and the seeds will be hybridized. Cross pollination will not affect the fruit, only the seeds inside.
Answer:

Introduction Magnets have existed for hundreds of thousands of years and have been used by many different cultures throughout this time. Magnets have been useful throughout the years because they can hold two things together just through the force of the metal in the magnet. With the world’s constantly changing technology, electromagnets have been evolved from magnets and are more useful than a regular magnet but in order for an electromagnet to work, an electric current needs to be present
Whether a material is magnetic depends on the material’s atoms”. A material’s atoms can effect what different materials that the magnet can pick up. Everything in the universe is made up of atoms and electrons. The electron moves around the atom and as it does this, it creates a magnetic field. In materials such as aluminum and copper, the magnetic fields of those certain atoms delete each other making the materials not magnetic. “In materials such as iron, nickel, and cobalt, groups of atoms are in tiny areas called domains. The north and south poles of the atoms in a domain line up and make a strong magnetic field. The arrangement of domains in an object determines whether the object is magnetic or not”. Because magnetic materials contain domains, this makes the material magnetic and attract other magnetic objects. What are the different kinds of magnets? Magnets are made up of many different materials such as “iron, nickel, cobalt, or a mixture of these metals”. Ferromagnets are created with those metals and produce strong magnetic properties. “A mineral magnetite is an example of a naturally occurring ferromagnet” from the combination of stronger metals. Another kind of magnet is the electromagnet. This kind of magnet is made from an electric current and an electromagnet consists of an iron core. Magnets can also be classified as
