Carbon dioxide emissions are contributing to climate change, which is causing average global temperatures to increase. These tem

perature increases have led to a loss of sea ice in the Arctic. Populations of polar bears, which depend on sea ice as part of their habitat, have declined as a result of this loss. The rate of Arctic sea ice loss is predicted to increase if the current temperature trends continue.
What is the best long-term solution to help maintain polar bear populations?

A. introducing plants capable of bioremediation to the Arctic

B. replacing fossil fuels with renewable energy sources

C. identifying new sources of fossil fuels around the world

D. establishing several protected regions in the Arctic

The best solution is - B. replacing fossil fuels with renewable energy sources.

By replacing the fossil fuels with renewable energy sources the enormous release of carbon dioxide into the atmosphere will be stopped and minimized because the renewable energy sources are not emitting Greenhouse gasses into the atmosphere.

Unfortunately, this type of energy sources still can not satisfy the demand, and also big problem represents the economic justification of their usage, and lots of countries are not willing to lose profit in order to protect the environment.

In studies of disease-discordant monozygotic twin pairs, one searches each pair for epigenetic differences.

<h3>What is DNA?</h3>

The DNA is the genetic material that is found in human beings. The DNA of a person contains the information that could be passed on from parents to the offspring and this is  the basis of inheritance.

In studies of disease-discordant monozygotic twin pairs, one searches each pair for epigenetic differences , focusing on those areas of DNA that are thought to be involved in the disorder.

What happens to macromolecules from food during digestion?
Scilla [17]

Answer:

Explanation:

. Chemical digestion is the biochemical process in which macromolecules in food are changed into smaller molecules that can be absorbed into body fluids and transported to cells throughout the body. Substances in food that must be chemically digested include carbohydrates, proteins, lipids, and nucleic acids.

2.A fat molecule, such as a triglyceride, consists of two main components—glycerol and fatty acids. Glycerol is an organic compound with three carbon atoms, five hydrogen atoms, and three hydroxyl (–OH) groups.

3. If it's in the table, it's an element! Atoms can join together - they form bonds together - to make MOLECULES. For example, two atoms of hydrogen hook together to form a molecule of hydrogen, H2 for short.

4. When atoms join together to form molecules, they are held together by chemical bonds. These bonds form as a result of the sharing or exchange of electrons between the atoms. It is only the electrons in the outermost shell that ever get involved in bonding.

A compound is a molecule made of atoms from different elements. There are two main types of chemical bonds that hold atoms together: covalent and ionic/electrovalent bonds. Atoms that share electrons in a chemical bond have covalent bonds. An oxygen molecule (O2) is a good example of a molecule with a covalent bond.

5.Beginning with energy sources obtained from their environment in the form of sunlight and organic food molecules, eukaryotic cells make energy-rich molecules like ATP and NADH via energy pathways including photosynthesis, glycolysis, the citric acid cycle, and oxidative phosphorylation.

What is the approximate temperature of the troposphere, mesosphere, and stratosphere.​
lakkis [162]

Answer:

Heat is produced in the process of the formation of Ozone and this heat is responsible for temperature increases from an average -60°F (-51°C) at tropopause to a maximum of about 5°F (-15°C) at the top of the stratosphere. This increase in temperature with height means warmer air is located above cooler air.
