One of the primary advantages of cell culture is the ability to isolate a single type of cell from a multicellular organism. How

has this advance changed the study of biology?
Single-type cultures are easier and cheaper to maintain than cultures made of mixed cell types.
Scientists can completely avoid using animal or human test subjects during their experiments.
Cultures with single cell types behave in culture exactly as they would behave in a tissue or organ.
Scientists know that any response during an experiment is associated only with that cell type.

Answer:

Scientists know that any response during an experiment is associated only with that cell type.

Explanation:

A cell culture is a group of cells that develops from a single original cell. Biologists can use cell cultures to test cell responses under controlled environmental conditions in order to study interactions between cells, and different processes occurs in it. Cell culture is one of the major tools used in the study of physiology and effect of toxic substances on the cells.

Pretty easy question (s) but I am not good at explaining things so I need help
luda_lava [24]

I'm guessing the rocket scenario is the first one and the asteroid one is the last. That being said...

1) The fuel in the rocket provides it with the energy it needs to propel itself into space. The rocket throttles at the bottom, allow it to break free from the earth's gravity by pushing against the earth's greater mass.

2) If you are inside of the bus, in a fixed spot not moving, and the bus is moving. That means you are moving in the same direction as the bus. If it stops, you're still moving at the speed that it was once originally moving at. Obviously, since you weigh less than the bus you are going to fly forwards.

3) There is no gravity or friction in space, so items won't slow down no matter what. Even if an object such as a meteor is flung into space with the tiniest bit of force it will keep flying through space at a consistent speed, since there's nothing to slow it down... unless it hits something else.

4) Looking back at the previous answer, the asteroid is flying through space at a consistent speed (which is really fast). Suddenly it comes in close range to the moon which is bigger in size, and thus has a stronger gravitational pull, and pulls the asteroid into it's field.

Which of the following regions experiences its greatest solar intensity in late June?
DaniilM [7]

Answer:

The correct answer is option A "Buenos Aires, Argentina, located near the Tropic of Capricorn"

Explanation:

Electromagnetic radiation transmitted by the sun. Sunlight based radiation can be caught and transformed into helpful types of energy, for example, warmth and power, utilizing an assortment of innovations. Notwithstanding, the specialized plausibility and practical activity of these advancements at a particular area relies upon the accessible sun oriented asset.

Each area on Earth gets daylight in any event part of the year.

The measure of sun based radiation that arrives at any one spot on the World's surface differs as indicated by:

Geographic area

Time of the day

Season

Local landscape

Local weather

The turn of the Earth is likewise liable for hourly varieties in daylight. In the early morning and late evening, the sun is low in the sky. Its beams travel further through the environment than around early afternoon, when the sun is at its most noteworthy point. On a sunny morning, the best measure of sun based energy arrives at a sunlight based gatherer around sun oriented early afternoon.

3. What can you say about the general relationship of the charge of the anion to the subscript of the cation?
Genrish500 [490]

Answer:

Cations are positively charged ion while anions are negatively charged ions formed by loosing and gaining of electrons respectively. Transition metals are metals in the middle of the periodic table with multiple oxidation states. The charge on the transition metal is equal to the oxidation state which varies from +1 to +7. The charge of transition metal can also be determined in neutral compound as long as one knows the charge or the oxidation state of the other atom in the compound. The charge of transition can also be determined in the case of neutral complexes where the transition element has combined with other atoms to form molecular complexes that are either positively or negatively charged, e.g. MnO4-. Lastly Neutral transition metal compounds which are soluble in water have a charge of +3 or less than+3.
