Answer:

Option-B

Explanation:

Muscle contraction refers to the generation of tension in the muscle caused by the actin and myosin filaments and can be categorized by the length of the muscle during the muscle contraction.

The isotonic contractions are a type of contraction during which a constant or regular muscle tension in the muscle is maintained as the length of the muscle changes. The tension is maintained when the force on the contraction exceeds the total load on the muscle.

Thus, Option-B is the correct answer.

Answer:

The correct answer is-b. isotonic

Explanation:

Isotonic contraction is the contraction in which the tension remains the same but the wrist muscle length changes which results in the movement of a body part. Two types of isotonic contractions are Concentric contractions and Eccentric contractions.

In concentric contractions, muscle contract and become short and Eccentric contractions is opposite to concentric contractions in which muscle lengthens. Isotonic contraction is the most common type of muscle contraction which is encountered within exercise. Thereofore the correct answer is b. isotonic.

The ________ division of the autonomic nervous system is often called the "rest-and-digest" division.
Ad libitum [116K]

Answer:

Parasympathetic nervous division

Explanation:

The parasympathetic division of nerves is a part of the autonomic nervous system which gets activated during the relax conditions.

The parasympathetic nervous system is the opposite of the sympathetic nervous system which gets activated during the stress condition.

The parasympathetic division gets activated when the level of cortisol and adrenaline gets decreased and the body responds by detoxifying, digesting and building immunity.

Thus, Parasympathetic nervous division is the correct answer.

I would believe it is the Ozone but since it’s not an option the Ferrel Cell is the westerlies and the polar cell is the polar easterlies. So, I would say go with 4! Hope this helps, goodluck! xoxo.

Is the amplitude of each wave (P, ORS, T) always the same in different cardiac cycles?
Citrus2011 [14]

No the amplitude of each waves are different on different cardiac cycles.

<u>Explanation:</u>

  • The PQRST waves are used to represent the atrial and ventricular depolarization and repolarization.  These waves are reflected in ECG.  
  • In this as the series, p occupies the first place then QRS complex and at last T wave. In the QRS wave complex,  R wave is said to be the largest wave.  
  • The direction and amplitude of r wave depend on the electrical picture. The R wave represents the ventricles depolarization so it is the largest wave.

When lemming populations decline, populations of Arctic foxes also decrease. The limiting factor on the population of Arctic fox
kolbaska11 [484]

The limiting factor on the population of Arctic foxes is density-dependent. In population ecology, density-dependent processes happen when population growth rates are regulated by the density of a population. Density-dependent factors are factors where the effects on the size or growth of a population vary with the density of the population itself.
