Rico and Bree are camping and have potatoes wrapped in foil to eat. Bree put her potato in the campfire for a while, but Rico did not. Now Bree's potato has a high temperature. What is the difference between the molecules of the two potatoes? *

Answers

There is no difference because both potatoes are made of the same type of molecules.

What is Molecules?

Molecule is a group of two or more atoms that are bound together with the help of some attractive forces. These attractive forces are known as chemical bonds. It is the smallest particle of a substance that has all the physical and chemical properties of that substance.

Atoms have a single nucleus with a positive charge protons surrounded by a cloud of negatively charged electrons. When these come close to each other, the electrons interact with each other and with the nucleus, lowering the total energy of the system, then the atoms bond together to form a molecule.

There are three types of molecules:

1. Molecule of an atom

2. Molecule of an element

3. Molecule of a compound

Thus, there is no difference because both potatoes are made of the same type of molecules.

Which of the following best characterizes the global role of photosynthesis in relation to global warming?


reproduction

circulation

respiration

digestion

Answers

Photosynthesis is a process by which plants use sunlight, water, and carbon dioxide to produce carbohydrates, and other biological compounds, which reduces the amount of carbon dioxide in the air. This is the difference between plants and animals. The carbon dioxide is stored in the plants until they decompose or are burned. So, for example, each fall when the trees lose their leaves and the plants die the level of carbon in the atmosphere goes up. The rest of the tree, bark etc., does not continue to absorb carbon. Plants only take in carbon so long as they are growing and not after they have reached their natural height. Planting trees and other plants is one component of the solution to global warming, but the number of plants we have now cannot consume more carbon than they already do, and there is some evidence that warmer temperatures make photosynthesis more difficult.

Describe the treatment goals for dialysis.

Answers

Answer:

The main goals are to keep your body in balance and keeping a safe level of certain chemicals in your blood.

Explanation:

Keeping your body in balance by removing waste, extra water, and salt to prevent those things from building up in your body. The certain chemicals are: potassium, sodium, and bicarbonate.

In dialysis, the main goals are to keep your body in balance and keeping a safe level of certain chemicals in your blood.

What do you mean by dialysis?

Dialysis is a procedure to remove waste products and excess fluid from the blood when the kidneys stop working properly. It often involves diverting blood to a machine to be cleaned.

Average life expectancy on dialysis is 5-10 years, however, many patients have lived well on dialysis for 20 or even 30 years. Talk to your healthcare team about how to take care of yourself and stay healthy on dialysis.

High blood pressure and diabetes are the two most common causes of kidney failure. They can also become damaged from physical injury, diseases, or other disorders.

Swallow hole: A cave that has collapsed because of gravity.

Sinkhole: Where a stream disappears into the ground.

What are Stalactites?

Mineral deposits known as stalagmites and stalactites are frequently seen in caves. The pointy, downward-pointing minerals that fall from the caves' roofs give rise to the stalactites.

On the other hand, stalagmites are created when minerals that fall from the roof are deposited on the ground afterward.

Show different life cycle patterns with the help of near labelled diagram

Answers

Answer:

The life cycles of all sexually reproducing plants follow a pattern of alternation between a haploid, sexual generation called gametophyte with a diploid, asexual generation called sporophyte.

This phenomenon of alternation between gametophyte (n) and sporophyte (2n) in the life cycle of a plant is called alternation of generations (Hofmeister, 1851).

Alternation of generations is of two types- isomorphic and heteromorphy. In isomorphic (or homologous) type both the alternating generations are morphologically similar, while in heteromophic (or heterologous) type of alternation of generations both the generations of life cycle are morphologically dissimilar.

harvest only very young fish

Answers

Answer: Limit the size of fishing fleets and catch size.

Explanation: Cod are nearly extinct therefore we either need to stop catching them or limit the amount you catch

The choice describes a strategy used to help restore cod populations is limiting the size of fishing fleets and catches. The correct option is A.

What are cod populations?

Atlantic cod, a fish that was essential to New England's economy, is being fished at historically low levels, and New England cod appears to be recovering from overfishing after many years.

Many people are concerned about eating fish because the IUCN has recently classified species including cod, haddock, and grouper as endangered. The fish that are linked to high bycatch rates are another worry for divers. Animals like dolphins and turtles are accidentally killed in the nets at this location.

Therefore, the correct option is A. limit the size of fishing fleets and catches.

3. pluripotent

Explanation:

The cells that are able to develop or differentiate a different kind of cells in the body of the individual are known as totipotent cells and this ability is known as totipotency. An example of such cells is found in the zygote.

Multipotent on the other hand are the cells that are able to develop into a specific kind of cell of tissues these cells are present and the example of this type of cell is adult stem cells. Whereas Embryonic stem cells are Pluripotent cells that are characterized as the cells that develop into any type of cell of the body of an organism.
