The muscle contracts when ATP supplies energy for thing filaments in a muscle fiber to slide over thick filaments. The correct answer is A.

Answer: The correct answer is  A) The muscle contracts.

During muscle contraction, the thin filaments ( actin filaments) slide pass over the thick filaments ( myosin) and the sarcomere ( unit of muscle contraction ) becomes short. This is explained through sliding filament theory.  

Supply of energy in the form of ATP is very important for the contraction of muscle.

The role of ATP is to prepare myosin for its  binding with actin by moving it to a state that has higher- energy. The thin filaments slide over the thick filaments and the contraction of muscle takes place.

rusak2 [61]

Using the gas pedal analogy, the proto-oncogene would be an accelerator since they promote cell division and deregulate apoptosis, while tumor suppressor would be the brakes since they constrain the progress of the cell cycle and induce cell apoptosis. An oncogene is, therefore, when the accelerator is stuck in down position and the brakes are not working.

Elden [556K]

Answer: G00gle

Explanation: Magnetic force, attraction or repulsion that arises between electrically charged particles because of their motion. The magnetic force between two moving charges may be described as the effect exerted upon either charge by a magnetic field created by the other.

natta225 [31]

According to the research, the correct option is control. Experiments are carried out to test a hypothesis by changing one variable at a time and including an unchanged variable termed a <u>control</u>.

<h3>What are Experiments?</h3>

It is the process by which one or more variables are intentionally manipulated by carrying out actions aimed at discovering or verifying certain phenomena.

In this sense, its basis is in the manipulation of the variables that are considered relevant, the control of strange variables and the randomization of the rest.

Therefore, we can conclude that according to the research, the correct option is control. Experiments are carried out to test a hypothesis by changing one variable at a time and including an unchanged variable termed a <u>control</u>.

sergeinik [125]

Answer:

The professor Bonefinder has made a mistake.

Explanation:

I't is true the Hominoid had a long snout, a large orbits that are partially enclosed, but they have no tail. This point is really critical because the morphology of an species is really important. The taxonomists use the information that morphology gave for many years to identify species, nowadays with molecular techniques some of those species are pulled apart, but the important matter is that hominoids had no tail.

So the professor Bonefinder analysis is incorrect because the hominoids have no tail.
