To balance the equation a coefficient of _needs to be in front of_<br> KCIO4 - KCl + O2

Dima020 [189]

Answer:

There needs to be a 2 in front of O2.

Explanation:

That would make 4 oxygen atoms and would balance the number of atoms and mass on each side. And, in a balanced chemical equation, mass and atoms are always conserved.

Which of the following is found inside a pollen grain?the female gametophyte,the male gametophyte,the megaspore,the sporophyte

mafiozo [28]

Answer:

the male gametophyte

Explanation:

Pollen grains are structures in the seed plants (spermatophytes) which contain vegetative cells but also reproductive cells - microgametophytes. Microgametophytes produce 2 male gametes or sperm cells. Vegetative cells produce pollen tube which is involved in the transfer of sperm cells to the ovule (female structure that forms female gametes). Pollen grains are different in shape, size and color, but all of them are enveloped with hard coat that has protective role.

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.

Distinguish between voluntary and involuntary actions.

sukhopar [10]

<h2>GREETINGS!</h2><h2>_____________________________________</h2>

<u>ANSWER</u><u>:</u>

<h2><u>DEFINITIONS</u></h2><h2>_____________________________________</h2><h3><u>VOLUNTARY MUSCLES:</u></h3>

Voluntary muscles are those muscles which work under our conscious control and can be controlled at will also we can choose choose them when to use and when not to use. These are simply SKELETAL MUSCLES attached to the bone, so all the movements of hand and legs and whatever u do are because of voluntary muscles.

<h3><u>__________________________________________________</u></h3><h3><u>INVOLUNTARY MUSCLES:</u></h3>

the muscles in the human body that do not work under our will and we cant control them. They are mainly controlled by the autonomic nervous system in the body. So, involuntary muscles include all the muscles whose activity which is not controlled by our NERVES. They are also called SMOOTH MUSCLES since they are present as the visceral layer over the organs.

<h2>_____________________________________</h2><h2>DIFFERENCES</h2>

1) VOLUNTARY MUSCLES are under our control but INVOLUNTARY MUSCLES are not under our control

2) VOLUNTARY MUSCLES are also known as skeletal muscles but INVOLUNTARY MUSCLES are also known as smooth muscles

3) VOLUNTARY MUSCLES are attached to the bones in the body, but INVOLUNTARY MUSCLES are attached to the soft hollow internal organs.

4) VOLUNTARY MUSCLES are controlled by the somatic nervous system. INVOLUNTARY MUSCLES are controlled by the autonomic nervous system.

5) VOLUNTARY MSUCLES require more energy. INVOLUNTARY MUSCLES require less energy.
