A patient exhibiting dermatitis, diarrhea, and dementia symptoms will most likely be lacking in which vitamin?
A patient with "the 4 D's" of dermatitis, diarrhea, and dementia and eventually death; is experiencing symptoms of lacking niacin (B3) and is suffering with is called Primary Pellagra. They are not getting enough niacin and tryptophan in their daily diet.
Secondary Pellagra is usually due to not being able to withstand niacin in a diet. Generally, alcoholism; severe diarrhea to the point of severe dehydration; and certain medications will cause this to happen.
Please select the word from the list that best fits the definition The energy from the sun that warms your face is transferred by a process called ______.
convection
convection
radiation
The right answer is Radiation.
Radiation, refers to the process of emission or propagation of energy and momentum involving a wave, a particle.
Solar radiation is the set of electromagnetic waves emitted by the Sun.
It is made up of the full range of radiation, from far ultraviolet like gamma rays to radio waves and visible light. Solar radiation also contains cosmic rays of moving particles of extremely high speed and energy.
Sunlight is necessary for human health:
* the day-night cycle holds most human biological cycles;
* Solar UV is necessary for the synthesis of vitamin D;
* Solar UV also contributes to the destruction of some living or surviving microbes or those that have contaminated bathing waters or waters that can be used as drinking water or irrigation, with less efficiency in turbid waters, or made turbid by human activities.
Answer:
3/c radiation

During heart surgery, red blood cells are damaged. When the blood passes through the lymphatic system, these damaged red blood cells are trapped and broken down by macrophages. In which organ in the lymphatic system does the breakdown of damaged red blood cells take place?
The right answer is The spleen.
The spleen belongs to the lymphatic system, its role and to filter the blood and purify it. It works mainly on the destruction and recycling of spent red blood cells (iron is used again for example for the production of hemoglobin).
Like the liver, the spleen also serves as a store of blood for the body.
Why does the cell membrane of the tube worm stop the flow of excess salt into its body?
To maintain a stable environment
The cell membrane of tube worm cells is selectively permeable, preventing minerals in the water from flowing into the cells. The cell membrane thus protects the cell from osmotic damage. By selectively preventing these minerals, the cell's environment is kept stable.
What is cell membrane ?The cell membrane, also known as the plasma membrane, is found in all cells and serves to separate the cell's interior from the outside environment. The cell membrane is made up of a semipermeable lipid bilayer. The cell membrane controls the transport of materials into and out of the cell.
The ease with which a molecule can pass through the cell membrane is referred to as the cell membrane's permeability. It also refers to the rate of passive diffusion through the cell membrane.
Cell membranes function as both barriers and gatekeepers. They are semi-permeable, which means that some molecules can pass through but others cannot. Small hydrophobic molecules and gases, such as oxygen and carbon dioxide, rapidly cross membranes.
Thus, The cell membrane of tube worm cells is selectively permeable, preventing minerals in the water from flowing into the cells.

Which energy conversion occurs during the process of photosynthesis?
In the process of photosynthesis, light energy is converted to chemical energy.
• The process by which green plants and some of the other organisms convert light energy into chemical energy is called photosynthesis.
• During the process of photosynthesis, the light energy is captivated and is utilized to transform carbon dioxide, water, and minerals into oxygen and other energy-rich organic compounds.
• In the absence of photosynthesis no synthesis of food will take place.
• The energy obtained by the process of photosynthesis is carried out by plants for millions of years and is accountable for the formation of fossil fuels used in industries.
Thus, during photosynthesis, light energy is converted to chemical energy.

What do all of the hexoses have in common? What makes them different?
An aldohexose is a hexose having an aldehyde functional group at carbon number one. A hexose is a monosaccharide with six carbons.
What are hexose sugars?Allose, Altrose, Glucose, Mannose, Gulose, Idose, Galactose, and Talose are a few examples of common aldohexoses.
Hexose sugars include galactose, fructose, and glucose as examples. Hexose sugars have six carbon atoms and are monosaccharides, which means that each of these sugars is made up of a single molecule.
Each of these sugars has a unique chemical formula, which will determine how many hydrogen and oxygen atoms are present in each sugar.
A sugar containing six carbons, glucose has the chemical formula C6H12O6. Thus, there are 6 carbon atoms, 12 hydrogen atoms, and 6 oxygen atoms in glucose.
Therefore, a hexose has an aldehyde functional group at carbon number one.

Which of the reactions of photosynthesis require pigments absorbing solar energy?
Answer:
During photosynthesis, a green pigment called chlorophyll is required to absorb solar energy. The reaction in photosynthesis that requires pigments to absorb solar energy is called LIGHT REACTION.
Explanation:
Light reaction is considered to be the first stage or phase during photosynthesis and the key elements that is needed for the reaction to take place is- sunlight and chlorophyll. Chlorophyll is a pigment that makes the leaves of the plant appear green. There is also another important function of chlorophyll that is to trap solar energy during the process of photosynthesis to convert the trapped solar energy into chemical energy- ATP molecules. These ATP molecules then form glucose- food for the plant.
