Answers

Answer 1

Answer:

A burning piece of wood is a chemical change, because you alter it, and it turns to ashes, and it is irreversible, where as you can make water cold again

Answer 2

Answer:

youre creating a new substance in a chemical reaction

Explanation:

by boiling water, you arent making anything new. you're just changing the form of the water.

by burning wood, you're inducing a chemical reaction because some new substance is being made with the reactants

Someone please help ill give you brainliest!!!

Answers

Answer:

Work is the transfer of energy , Energy is the capacity for doing work , and Power is work being done in a unit of time.

There are 2 types of energy

Kinetic Energy : Energy of Motion

Potential Energy : Stored Energy

When calculating work energy and power you use WORK = W=Fd

Because energy is the capacity to do work , we measure energy and work in the same units. Power's SI unit of measurement is the Watt, representing the generation or absorption of energy at the rate of 1 Joule/sec. Power's unit of measurement in the English system is the horsepower, which is equivalent to 735.7 Watts.

Answers

Answer:

antibodies - proteins (gamma globulins)

Explanation:

The ribosome, a biological component found in the cytoplasm of cells, is in charge of producing luciferase.

what is  cytoplasm:

The ribosomes are responsible for producing all proteins.The cytoplasm of a cell contains ribosomes, which are cell organelles that allow mRNA and tRNA to function so that proteins can be produced.All of the components of a eukaryotic cell outside of the cell nucleus are referred to as cytoplasm in cell biology. Nucleoplasm is the name for the substance that makes up the nucleus and is enclosed within the nuclear membrane. The cytosol, a gel-like fluid, the organelles, and numerous cytoplasmic inclusions are the three primary elements of the cytoplasm. About 80% of the cytoplasm contains water, and it is typically colorless.After removing the cell organelles and particles, groundplasm—a submicroscopic ground cell material or cytoplasmic matrix—remains. The bigger organelles, including ribosomes, mitochondria, plant plastids, lipid droplets, and vacuoles, are suspended in this highly intricate, polyphasic structure known as the hyaloplasm of light microscopy.The majority of cellular functions, including several metabolic pathways, including glycolysis, and procedures like cell division, take place within the cytoplasm. The concentrated inner region is known as the endoplasm, and the cell cortex or ectoplasm is the name of the outside layer.

This is so that codons can be inserted, amino acids can be formed, and all the proteins, including luciferase, can be formed. The ribosome traps the mRNA molecule and moves over it.

Explanation:

how does coriolis effect affect the climate zones in the world? PLEASE HELP! I WILL GIVE BRAINLY TO PROPER ANSWER!

Answers

Answer:

Please Mark as Brainliest

Explanation:

The development of weather patterns, such as cyclones and trade winds, are examples of the impact of the Coriolis effect. ... As warm air rises near the Equator, for instance, it flows toward the poles. In the Northern Hemisphere, these warm air currents are deflected to the right (east) as they move northward.

The Coriolis effect was presumed to be the reason for the rotation of low pressure areas which is anticlockwise in the Northern Hemisphere and Clockwise in the Southern Hemisphere. The problem with this is that it would carry the winds to the east in either hemisphere because of the velocity of the surface being faster near the equator going east bound at the equator at just over 1,000 miles per hour. The velocity drop by 35 degrees north or south is to about 860 mph. The only problem with this concept is that it doesn’t sustain a recurving circular flow. South bound winds are slower and would carry to the west.

There is only one structure that explains the full vortex structure of storms. That structure is an Electromagnetic particle vortex. Sorry folks the Coriolis effect is one of those things that needs sent to the dustbin of history (Trash for Americans).

The weather plasma flow linkages are being well studied now. There is no reason to continue to teach Coriolis Effect regards rotation of storms. It does have effect in things like the massive ocean currents and the generalized flows on earth of winds but it doesn’t affect rotation of storms. Even there we are learning that motion north and south from the equator is primarily electrical in nature.


If the DNA code reads CCAATTGG then the tRNA code would read?

Answers

Answer:

CCAAUUGG

Explanation:

A tRNA is all the letters stay the same unless there is a T or a U. a T turns into a U and vise versa.

In case DNA code offers the reading CCAATTGG, the reading of the code tRNA would be:

CCAAUUGG

The term "tRNA or Transfer RNA" is described as the small atoms that may function for the purpose of carrying/transferring amino acids.In the given situation, "tRNA" code for the provided DNA code reading would be similar to the DNA except for T. The letter "T" would be replaced with U in tRNA and U become T while converting it to DNA.

Thus, "CCAAUUGG" is the correct answer.

What is one reason scientists are trying to culture meat in laboratories instead of simply hunting or raising animals?​

Answers

Answer:

Many reasons - but a really good question.

Explanation:

Cruelty - eating meat poses ethical issues to some people. They dont eat meat because they dont believe animals should be harmed. Growing laboratory meat takes away the need for slaughter.

Land used - a big issue with producing meat is the amount of land we need to raise cattle and to grow the food to feed cattle. Rainforest, woodlands, moorland have to be destructed to make way for pasture land for cattle. The food that cattle or animal eats also needs to be grown, which requires more land. Laboratory grown meat doesnt require all the pasture space for raising or feeding animals.

Water use - the amount of water that goes into producing meat is very high when compared to amount of meat that you get back. Water availability is another global issue that may be able to be addressed by lab produced meat.

When animals are reared from meat, they may be killed in unethical ways thereby making it ethically irresponsible to raise animals for meat.

Animals are widely used as food. This food from animals or having animal origin is known as meat. The ethical issues are of key importance in raising meat for food.
