Tachycardia is a condition when the heart rate is greater than 100 beats per min at rest. The electrocardiogram is a diagnostic tool that measures and records the electrical activity of the heart. Bradycardia on the other hand is when the heart rate is slower than normal. The Tachycardia and bradycardia can arise from either the SA node or from other areas of the cardiac.

Within an infected wound bed, many cell types are involved in protecting the host and eliminating the "foreign invaders" to prom

Oxana [17]

Explanation:

All vital organs begin to lose some functionality as one ages during adulthood. Aging changes occur in all cells, tissues and organs of the body and affect the functioning of all body systems.

The living tissue is made up of cells. There are many different types of cells, but they all have the same basic structure. Tissues are layers of similar cells that fulfill a specific function. Different types of tissues group together to form organs.

There are four basic types of tissue:

The connective tissue supports the other tissues and joins them. This includes bone, blood and lymphatic tissue, in addition to the tissues that provide support and structure to the skin and internal organs.

The epithelial tissue provides coverage for the superficial and deeper layers of the body. The skin and lining of the ducts inside the body, such as the gastrointestinal system, are made of epithelial tissue.

Muscle tissue includes three types of tissue:

Striated muscles, such as those that move the skeleton (also called voluntary muscles)

Smooth muscles (also called involuntary muscles), such as the contents in the stomach and other internal organs

Myocardium, which makes up most of the wall of the heart (also an involuntary muscle)

Nervous tissue is composed of nerve cells (neurons) and is used to carry messages to and from different parts of the body. The brain, spinal cord and peripheral nerves are composed of nerve tissue.

Which principle helps to explain the reason behind why alleles for a single trait separate from each other when gametes are made

Oksanka [162]

<span>Segregation

For a trait to show or express itself in an individual it must have two types of the same allele (for example P and p) showing on the chromosomes. The showing of both alleles on an offspring's chromosomes means that both parents have the same trait and that is why there is a chance for an allele to become dominant in other words to express itself in the offspring. However if only one allele is transferred in the genes of the offspring that means that the trait that the allele is responsible for, will remain unexpressed.</span>

Ou are told that the cells on a microscope slide are plant, animal, or bacterial. You look at them through a microscope and see

grandymaker [24]

Answer:

The correct answer is c) are plant cells.

Explanation:

The cells cannot be animal cells, because they have not wall (this kind of cells has only plasma membrane). In addition, eukaryotic cells have membrane-bound organelles (which are surrounded by a phospholipids membrane, such as endoplasmatic reticulum, Golgi apparatus, lysosomes, etc.), whereas prokaryotic cells lack them. Since plant cells are eukaryotic and bacterial cells are prokaryotic, the cells you are looking are plant cells.
