The right answer is ISOTONIC contraction (not isometric)


During an isotonic contraction, the length of the muscle varies but not the tension. For example, an athlete achieves (approximately) isotonic contraction when he lowers an extremely heavy weight, at a slow and constant speed, against maximum resistance.

Answer:

When the body is lifting weight, the muscles of the body become shorter and thicker but the tension or tone of the body remains the same.This condition is known as isotonic contraction.

The isometric contraction can be defined as the condition when a person pushes a wall or attempt to lift a huge boulder, the muscles involved in this exercise remains at a constant length while the tension against the muscles increases.

So, the given exercise is isotonic contraction.

When a plant is genetically identical to its parent plant what is this called
tamaranim1 [39]

Hello! My name is Zalgo and I am here to help you out on this amazing day. The way that the younger plant looks the same as the parent plant is because of "Asexual Reproduction". Asexual Reproduction is how plants can reproduce. Considering it is a plant and not a human asexual means that plants reproduce without the need of "sexual intercourse".

I hope that this helps! :P

Check Your Understanding<br> Question: What is an adaptation?
AleksandrR [38]

Answer:

an adaptation can be defined as an inherited trait which confers an evolutionary advantage to the organism in a certain environment

Explanation:

An adaptation, also known as an evolutionary adaptation, can be defined as any physiological and/or morphological inherited trait related to the improved evolutionary fitness of one organism in a particular environment. An adaptation improves the chances of survival and reproduction in a certain environment, thereby organisms carrying the adaptation have more chances to produce descendants and pass their genes to the next generation. Some classical examples of evolutionary adaptations include the long necks of giraffes that help them to eat leaves at the top of trees, light bones of flying birds, etc.
