Answer: C. Increased pollution

Industrialization is the process of development of industries, in order to manufacture goods and products on a large scale by utilizing human and machinery resources. Previous industries in the post industrial societies might have expelled out wastes in the form of gases, liquids and solids produced during the manufacturing process. These wastes could have contaminated air, water and soil of the neighboring environment. Therefore, increase in pollution is the only negative impact that postindustrial society has exerted on the environment.

Arte-miy333 [17]

Answer:

Calcium binds to troponin C
Troponin T moves tropomyosin and unblocks the binding sites
Myosin heads join to the actin forming cross-bridges
ATP turns into ADP and inorganic phosphate and releases energy
The energy is used to impulse myofilaments slide producing a power stroke
ADP is released and a new ATP joins the myosin heads and breaks the bindings to the actin filament
ATP splits into ADP and phosphate, and the energy produced is accumulated in the myosin heads, starting a new cycle
Z-bands are pulled toward each other, shortening the sarcomere and the I-band, producing muscle fiber contraction.

Explanation:

In rest, the tropomyosin inhibits the attraction strengths between myosin and actin filaments. Contraction initiates when an action potential depolarizes the inner portion of the muscle fiber. Calcium channels activate in the T tubules membrane, releasing <u>calcium into the sarcolemma.</u> At this point, tropomyosin is obstructing binding sites for myosin on the thin filament. When calcium binds to troponin C, troponin T alters the tropomyosin position by moving it and unblocking the binding sites. Myosin heads join to the uncovered actin-binding points forming cross-bridges, and while doing so, ATP turns into ADP and inorganic phosphate, which is released. Myofilaments slide impulsed by chemical energy collected in myosin heads, producing a power stroke. The power stroke initiates when the myosin cross-bridge binds to actin. As they slide, ADP molecules are released. A new ATP links to myosin heads and breaks the bindings to the actin filament. Then ATP splits into ADP and phosphate, and the energy produced is accumulated in the myosin heads, which starts a new binding cycle to actin. Finally, Z-bands are pulled toward each other, shortening the sarcomere and the I-band, producing muscle fiber contraction.

9. What is always true of a binary compound? It has a double bond. It has two elements. It has covalent bonds. It has two atoms.

juin [17]

Answer

Correct answer is :It has two elements

Explanation

A binary compound is a compound that is made up of two of the elements in the periodic table. Some examples of binary compounds are $NaCl$ and $N_2O$ . This means that a binary compound can have more than 2 atoms as in the case of hydrogen oxide. Some binary compounds are ionic as in the case of sodium chloride.This shows that they do not necessarily have to have covalent bonds. This also rules out the possibility that they may always have double bonds as ionic compounds are bound together by ionic bonds. The only thing that will always be true of binary compounds is that they will always have 2 elements.
