compare the four kinds of tissues connective tissue, epithelial tissue, muscle tissue, and nervous tissue. hi and also if you do
kirza4 [7]
<h3><u>Connective tissue:</u></h3>

It is the layer under the epithelial tissue in the body. It is stronger than epithelial tissue and is found in many organs. It provides protection.

<h3><u>Epithelial tissue:</u></h3>

It covers the outside of the body like a veil. located in the outermost part of the body. Protects the body against microbes and infections.

<h3><u>Muscle tissue:</u></h3>

It is located in the joint areas and forms the support and movement system. It allows us to make bodily movements.

<h3><u>Nervous tissue:</u></h3>

It is the fastest communication tissue. It allows us to feel pain and the sense of touch. It is impossible to repair this tissue after it is damaged. It causes paralysis. It is very important as it plays a role in the activity of neural transmission.

How many distinct stages must occur between the point when light first encounters chlorophyll and the point at which
Novay_Z [31]

Explanation:

<u>Three.</u>

Photosynthesis produces glucose and O2 from inorganic CO2, light energy and water.  This occurs in distinct steps: 1) light fixation,  2) electron transport and NADPH production 3)  ATP generation, then 4) carbon fixation and carbohydrate production.

6CO2 + 6H20 + (energy) → C6H12O6 + 6O2

Further Explanation:

Photosynthesis is a chemical process, essential to plant and other primary producers producing energy. As oxygen is emitted, energy in the form of glucose molecules is created from light, water, and carbon dioxide. It happens in several complicated stages, photosynthesis is a speed-limited process, depending on several factors including concentration of carbon dioxide, ambient temperature and light intensity; energy is extracted from photons, i.e. light particles, and water is used as a reduction agent. It occurs in the thykaloids, where pigment molecules live like chlorophyll.

Photosynthesis occurs in several complex steps and is a reaction of a small duration, depending on several fa factors including carbon dioxide concentration, ambient temperature and light intensity; the energy is retrieved from photons, I.e. particles of light, and water is used as a reducing agent. Water supplies the chlorophyll in plant cell with replacement electrons for the ones removed from photosystem II.

Additionally,

  • Water (H2O) divided into H+ and OH-by light during photolysis serves as a source of oxygen along with acting as a reduction agent; it reduces the NADP molecule to NADPH by supplying H+ ions and generates molecules of the energy storage molecule ATP through an electron transport chain.
  • This happens in the thykaloids, where pigment molecules reside like chlorophyll.
  • Later, NADP and NADPH are used in dark reactions during the Calvin cycle, where monosaccharides or sugars such as glucose are produced after several molecules have been modified. These store energy in their bonds which in the mitochondria can be released in respiration.

Does a moving magnetic field creat a megnetic field
faust18 [17]

Answer:

Explanation:

A moving charge causes a magnetic field and a moving magnet causes an electric field. If you change your frame of reference to that of the charged particle, the magnetic field disappears. Same is true for the magnet. Changing your reference frame to that of the magnet will make the electric field disappear.
