I hope this information helps you :)!

Linnaeus divided nature into three kingdoms: animals, vegetable (or plant), <span>and minerals. The animal and plant kingdoms were further divided into </span><span>smaller, more inclusive categories based on physical characteristics. </span><span> As time passed, and knowledge increased, other scientists added to </span><span>Linnaeus’ original system.

If a flare occurs on the Sun 4 astronomical units away how much time would pass before a robot at that distance see the light fl

neonofarm [45]

The time that would elapse before a robot at a distance see the light flash is : 2000 secs

<h3 /><h3>Analysis of the solution </h3>

<u>Given data :</u>

Distance = 4 AU

Time for light to reach the earth = 8 mins 20 seconds

speed of light ( c ) = 299,792,458 m / s

To resolve this we will apply the equation below

Time = Distance / Speed ------ ( 1 )

where : Distance= 4 AU, speed = c

Therefore :

Time = 4 AU / c

AU / c = ( 8 * 60 + 20)

Hence the time that would elapse before a robot at a distance see the light flash will be

Time = 4 ( 8*60 + 20) = 2000 secs

Explain how microscopic and macroscopic anchoring of muscle filaments enables you to bend your elbow.

mixer [17]

The development and dissolution of cross-bridges connecting myosin head binding actin ratchet the thin and the thick filaments past one another in response to nervous system motor output. The muscle fibers get shorter as a result of this sliding movement since the filaments are anchored.

<h3>Briefing:</h3>

Muscle contractions attached to a hard endoskeleton are necessary for human body movements. Tendons connect muscles to bones, which are made of fibers that are built up from the sarcomere, a basic structural component. Within the sarcomere, the thin and the thick filaments have different places of attachment. Myosin head and actin cross-bridges develop and break in response to nervous system motor output, ratcheting the thin and the thick filaments past one another. This sliding motion shortens individual muscle fibers because filaments are attached..

Additionally, muscular contraction causes the boy's bones to shift in relation to one another as the fibers themselves are a component of the muscles and are related to bones at either end. Thus, muscle function—such as the bending of either an elbow by contracting the biceps—is made possible by the structural anchoring between muscles and filaments.
