Describe how the EMG signal (a voltage) arises from muscle activity

Answers

Answer: The EMG signal is a biomedical signal that measures electrical currents generated in muscles during its contraction representing neuromuscular activities. The nervous system always controls the muscle activity (contraction/relaxation). ... EMG signal acquires noise while traveling through different tissues. EMG signals are recorded by placing electrodes close to the muscle groups. When the muscle is activated, the length of the muscle decreases and the muscle, skin and electrodes move with respect to one another. At that time, the electrodes will show some movement artifacts

Explanation:

EMG signals are recorded by positioning electrodes close to the muscle groups. It is the arrangement that helps in the monitoring of EMG signals from muscle activity.

What do you mean by EMG signals?

EMG signals may be defined as a biomedical signal that estimates electrical currents provoked in muscles during their contraction illustrating neuromuscular activities.

When the muscle is stimulated for any mechanism, the length of the muscle declines, which leads to the muscle, skin, and electrodes moving with regard to one another.

The EMG signals always arise from the electrical activity of the muscle fibers which are stimulated during the time of contraction.

Therefore, EMG signals are recorded by positioning electrodes close to the muscle groups. It is the arrangement that helps in the monitoring of EMG signals from muscle activity.

Answers

Answer:

xylem & phloem are present in both woody and herbaceous stems

Explanation:

Vascular system is present in both, woody and herbaceous stems. Thus, option A, and D are correct.

What are vascular tissues?

In vascular plants, A tissue which is complex in nature, formed by more than one type of cells are called as vascular tissues. Two main types of vascular tissues are:

XylemPhloem

The transportation of water from roots to stem and leaves of the plant is carried out by xylem. Xylem consist of tracheids and vessel elements, which have different characteristics,  but both play significant role in transportation of water and nutrients.  

The soluble organic compounds synthesized during photosynthesis in the plants are transported by another vascular tissue called as phloem, in process called translocation. It consists of sieve elements, parenchymal cells, fibers, and sclereids.

Therefore xylem and phloem are present in both, woody and herbaceous stems.

Is this active or passive transport?

Answers

Answer: Passive transport

Explanation: If the direction is from left to right, then it is passive. Passive transport is like unconscious, like osmosis. If I open my lunchbox and I have a peanut butter sandwich, the peanut butter smell (molecules) will naturally spread around and so someone standing next to you will smell it, and someone 3 seats away from you will smell it. Note that it is EVENLY spreading out, so after a while the person sitting 3 seats away from you will smell the peanut butter with a similar intensity as the person sitting next to you. Active transport is doing something forcefully. If the direction was right to left, then it would be active transport. :D

Why do we have different cells in our bodies if every cell has the same DNA?

The genome of a cell contains in its DNA sequence the information to make many thousands of different protein and RNA molecules. A cell typically expresses only a fraction of its genes, and the different types of cells in multicellular organisms arise because different sets of genes are expressed.
