The model shows a carbon cycle in an ecosystem.
Which process decreases the amount of atmospheric carbon dioxide?
A animal respiration
B factory emissions
C photosynthesis
D plant respiration
Answers
Answer:
C. Photosynthesis
Explanation:
A. Animal Respiration increases the ammount of carbon dioxide because the animals are exhaling the carbon dioxide.
B. Factory Emissions release carbon dioxide because of the fossil fuels that are being burned.
D. Plant respiration increases the amount of carbon dioxide because, as much as they do take in carbon dioxide, they also release carbon dioxide.
C. Photosynthesis is the only available answer because the plants are turning the carbon dioxide into oxygen within the process.

DNA polymerase cannot replicate DNA unless an RNA primer is first attached to the template strand. This is because DNA polymerase can only _____.
Answers
DNA polymerase cannot replicate DNA unless an RNA primer is first attached to the template strand because DNA polymerase cannot initiate nucleotide synthesis.
What is DNA replication?DNA replication is the process by which new and identical copies of a DNA molecule is synthesized from an old strand of DNA.
DNA replication occurs with the aid of an enzyme called DNA polymerase as it is responsible for adding nucleotide bases to the new DNA strand.
However, DNA polymerase cannot replicate DNA unless an RNA primer is first attached to the template strand because DNA polymerase cannot initiate nucleotide synthesis.

If there is not enough carbohydrate intake, how does the body form glucose?
If there is a glucose shortage, how does the body produce energy?
Answers
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.

The leading cause of limited water supplies is _______. a. low precipitation b. overuse c. limiting use d. government please select the best answer from the choices provided a b c d
Answers
The leading cause of limited water supplies is low precipitation. Anything will not be limited until a huge production has been created. Hence, overuse, limiting use, and government are not responsible for the cause of limited water supply.
What do you mean by Precipitation?Precipitation may be defined as any sort of water that originates in the Earth's atmosphere and then falls onto the surface of the Earth. It includes snow, rain, hail, dew, etc.
Precipitation is considered the major component of the water cycle that mediates the transport of water movement across the planet. If it declines, the supply of water gets limited.
Therefore, the leading cause of limited water supplies is low precipitation.
