Light enters the eye through the cornea, the clear, curved layer in front of the iris and pupil. ... By changing its shape, the lens focuses light onto the retina. Through the action of small muscles (called the ciliary muscles), the lens becomes thicker to focus on nearby objects and thinner to focus on distant objects.

What is the hydrolysis of atp and preparation for reattachment to the thin filament by the myosin head called?
QveST [7]

The hydrolysis of atp and preparation for reattachment to the thin filament by the myosin head called the recovery stroke.

<h3>What is myosin ? </h3>

Myosins are a class of motor proteins well recognized for their functions in the contraction of muscles and a variety of other eukaryotic motility processes. They are ATP-dependent and in charge of motility based on actin. By Wilhelm Kühne, the first myosin was identified in 1864.

<h3>When the myosin pulls the actin what is happening?</h3>

The actin is drawn along by the myosin head as it advances in the direction of the M line. The filaments migrate nearer the M line by around 10 nm as the actin is tugged. The power stroke is the name given to this motion because it is where force is generated.

A state is looking to reduce the cost of transportation, which uses 7.10×10^14 BTUs per year. Currently the cost of 10^6BTUs is
Ilia_Sergeevich [38]

Answer:

$ 284 million dollars

Explanation:

If the energy usage of all transportation is 7.10 × 10¹⁴ BTU per year, if their efficiency is to increase by 20%, The new energy usage will be (1 + 20/100)7.10 × 10¹⁴ BTU per year = (1.02)7.10 × 10¹⁴ BTU per year = 7.242 × 10¹⁴ BTU per year.

The energy saved is thus the difference 7.242 × 10¹⁴ BTU per year - 7.10 × 10¹⁴ BTU per year = 0.142 × 10¹⁴ BTU per year.

Since 10⁶ BTU costs $ 20.00, then,

0.142 × 10¹⁴ BTU costs 0.142 × 10¹⁴ BTU × $ 20.00/10⁶ BTU = $ 2.84 × 10⁸ per year = $ 284 million dollars

So the state saves $ 284 million dollars in one year
