how much will atmospheric carbon change in 10 years
Answer:
Explanation:
Carbon dioxide is a greenhouse gas: a gas that absorbs and radiates heat. Warmed by sunlight, Earth’s land and ocean surfaces continuously radiate thermal infrared energy (heat). Unlike oxygen or nitrogen (which make up most of our atmosphere), greenhouse gases absorb that heat and release it gradually over time, like bricks in a fireplace after the fire goes out. Without this natural greenhouse effect, Earth’s average annual temperature would be below freezing instead of close to 60°F. But increases in greenhouse gases have tipped the Earth's energy budget out of balance, trapping additional heat and raising Earth's average temperature.
Carbon dioxide is the most important of Earth’s long-lived greenhouse gases. It absorbs less heat per molecule than the greenhouse gases methane or nitrous oxide, but it’s more abundant and it stays in the atmosphere much longer. And while carbon dioxide is less abundant and less powerful than water vapor on a molecule per molecule basis, it absorbs wavelengths of thermal energy that water vapor does not, which means it adds to the greenhouse effect in a unique way. Increases in atmospheric carbon dioxide are responsible for about two-thirds of the total energy imbalance that is causing Earth's temperature to rise.
A new dog breed is less likely to cause an allergic reaction in humans. Which statement explains how artificial selection led to the development of this desirable trait?
Different dogs were bred with other animal species such as cats to introduce new nonallergic traits to obtain the new dog breed.
Different dogs were bred with other animal species such as cats to introduce new nonallergic traits to obtain the new dog breed.
Different dog breeds were chosen for nonallergic traits and bred with each other to obtain the new dog breed.
Dogs were trained over generations to not produce and release proteins that cause allergic reactions in humans to obtain the new dog breed.
Dogs were kept outdoors over generations to build up a natural defense against allergens in the environment to obtain the new dog breed.
Answer:it is c
Explanation:cuz it is
Answer:
C
Explanation:
Because they would test the dogs for traits and then selectively breed them
Explain how a concentration gradient, a membrane protein, and hydrogen ions work together to provide a mithochondrion with energy.
Answer:
Mitochondria within the electronic transport chain, are responsible for producing the energy that the cell needs, adjusting its operation to meet the metabolic needs of the body.The mitochondrion is the place where oxygen is consumed from aerobic organisms through various electron carriers and proton translocators (H +).
Explanation:
The lipid matrix of the membrane provides an impermeable barrier to ion translocation, as well as a topological organization to the catalysts in the membrane matrix that allows them to transport both e- and ions within and across the membrane in vector form. The transformation of oxidative energy into other forms of energy is carried out, initially, by generating a transmembrane electrochemical potential difference of H + ions (protomotive force). This force is the product of the asymmetric distribution of H + on both sides of the membrane, as those are translocated through it by the enzymatic complexes of the respiratory chain.The protomotive force is made up of two closely related components: one, function of the difference in chemical concentration of hydrogens across the membrane (a pH gradient) and another, dependent on the difference in electrical charge of H + ions on both sides of it (an electrical potential gradient). Gradients of electrical charge and chemical potential produce a field in which a force is exerted that tends to attract previously expelled protons into the mitochondria. It is the enzymatic complex of ATPase, the means by which the thermodynamically reversible translocation of H + ions is catalyzed. At the same time, the chemical activity of the H + on both sides of the membrane causes a change in the equilibrium constant of the enzyme, inducing it to catalyze the synthesis of ATP.

Sophie visited Carlsbad Caverns with her family during her summer vacation, and she was amazed at the cave’s formations. She learned that the cave was formed from minerals.
Rearrange the phrases describing one of the ways minerals form into the correct order. Place the earliest stage of mineral formation at the top. Place the final stage at the bottom. (Write 1 2 3 or 4 in order)
1. a solution forms from a liquid and dissolved substances
2. a warm solution flows through a crack in the rocks there
3. elements and compounds leave as the solution cools
4. elements and compounds crystallize
BASICALLY SAY WHICH STEPS GO FIRST IN MINERAL FORMATIONS! PLESSS
Answer:
The ways through which the minerals form include the following order:
2. a warm solution flows through a crack in the rocks there
1. a solution forms from a liquid and dissolved substances
3. elements and compounds leave as the solution cools
4. elements and compounds crystallize
Explanation:
From the explanations above, it could be seen that a warm solution (most probably water) flows through the cracks in the rocks leading to dissolution of substances to form liquid. When the liquid cools, the elements leaves and crystallize as compounds.

Explanation:
The cells of both unicellular and multicellular organisms carry out life processes. With respect to life processes, what advantage do multicellular organisms have over unicellular organisms? 1) Their cells reproduce more quickly. 2) Their life processes occur over a shorter time period. 3) Their cells can specialize in certain functions. 4) Their cell division is more efficient.
Answer:
Their cells can specialize in certain functions
Explanation:
This because multicellular organisms are organisms that are made up of several cells which aid it's complexity and lifespan. The cells in muiticellular organisms carries out specialise function or task which give them long lifespan. This long life span is achieved because of various cells that maintain their processes, the cells forms tissues, tissues to organs, organs to system and they all perform different specialized functions.
