Answer:

Mass is the amount of matter in an object.

Explanation:

Mass of object is defined as the amount of matter contained inside an object.                            It remains same at every location in the universe. It can be measured using balance. The relation between mass and weight is given by :

W = m g

g is the acceleration due to gravity, g = 9.8 m/s²

And W is the weight of object and m is its mass

The weight of an object is due to the force of gravity on an object. It varies with respect to location.

Hence, the correct option is " Mass is the amount of matter in an object ".

The smallest contractile unit within skeletal muscle would correspond to the distance between which two points in the figure?
Tpy6a [65]

The distance between 1 and 7 spans a sarcomere correspond the structure at B is covered by the perimysium.

<h3>What is the smallest contractile unit within skeletal muscle?</h3>

A sarcomere comprises the segment between two consecutive Z lines and is the contractile unit of the muscle fiber, as it is the smallest portion of the muscle fiber capable of contraction and distension.

In this case, the distance between points 1 and 7 has the smallest structure of a skeletal muscle and corresponds to figure B.

galina1969 [7]

Answer:

C). stop taking vitamin B-6, because he's showing signs and having symptoms of vitamin B-6 toxicity.

Explanation:

Increase amount of  vitamin B6 lead to lack of muscle control and coordination causing numbness in  the body. walking is also painful and unsteady after the side effects of increase amount of Vitamin B6 appears. High amount of Vitamin B6 can also cause nerve damage due to which coordination of body is also affected.

lesya692 [45]

The question is incomplete as it does not have the options which are:

A) eight legs.

B) two pairs of antennae.

C) a sessile lifestyle.

D) an open circulatory system.

E) parapodia.

Answer:

D) an open circulatory system.

Explanation:

In the given question, the characteristics of an organism are given which are:

1. Exoskeleton- outer covering composed of cuticle

2. system of tubes for gas exchange- do not respire but has tubes called trachea from which the air diffuses

3. modified segmentation- segmented bodies

All these characteristics show that the organism belongs to the Arthropods group of animals.

The Arthropods since having trachea for the diffusion of gas, therefore, possess an open circulatory system in which blood does not flow in the vessels but the open cavities in the body.

Thus, Option-D is the correct answer.
