It is described as a polar molecule because of an unequal sharing or electrons, causing the molecule to have a more bent shape.
Explanation:
Electrons are attracted a bit more to the oxygen and spend more time with them than the hydrogen.
a variety of factors can inhibit or enhance calcium absorption. indicate whether each situation increases or decreases calcium absorption by dragging it to the appropriate column.
Calcium is very important to the organism, and different factors influence its absorption. Pregnancy, Infancy, Vitamine D increase calcium absorption. Oxalic acid, phytic acids, and being over 70 years old decreases absorption
------------------------------------------
Calcium is a highly significant mineral for the appropriate development and functioning of the organism.
Different factors influence the mineral absorption, favoring it or limiting it.
Among the factors that might favor calcium absorption, we can mention
PregnancyIn the second and third trimesters of pregnancy, calcium absorption is the greatest. The intestinal absorption of calcium in women during this period increases to meet different demands. Calciotropic hormones are involved in the process.
Vitamine DVitamine D is one of the principal factors involved in calcium regulation. Vitamine D helps to double calcium absorption through the thin intestine.
InfancyDuring infancy, the body is growing, bones are developing, and the body needs to consume a high amount of calcium to accomplish these functions.
Calcium is a baseline mineral to provide children while growing, especially in their first periods of life.
Among the factors that limit calcium absorption, we can mention
Age exceeding 70 years oldElder people consume less food, and together with food consumption decrease, a less amount of necessary mineral is consumed.
With aging, calcium absorption decreases approximately 20% in the intestine.
Oxalic acid and Phytic acidMany substances, together with ingested calcium, form compounds that impede mineral absorption through the small intestine.
So in the presence of substances such as oxalic acid and phytic acid, calcium absorption is limited.
It is recommended not to consume food rich in calcium and food rich in these other substances simultaneously.
Pregnancy, Infancy, Eating vitamine D-enriched food ⇒increases calcium absorptionOxalic acid in spinach, high fiber diet rich in phytic acids, and being over 70 years old ⇒ decreases calcium absorption-----------------------------------------------

Disease or disorder that affects the nervous systems
Answer:
There are many diseases/disorders that affect the nervous system, but here are a few:
Alzheimer's disease
Parkinson's disease
Epilepsy
Stroke
Explanation:
Alzheimer's disease: Alzheimer's disease is a progressive disease (gets worse and worse overtime) that destroys your memory. When a person has Alzheimer's disease, their neurons (nerve cells) get damaged and eventually die all throughout the brain. Some problems people with this disease can experience are: getting lost easily, personality/behavior changes, memory loss (obviously), and need help with self-care and daily things.
Parkinson's disease: Parkinson's disease is a progressive disorder that affects one's movement. Because the nerve cells are damaged, the dopamine (type of neurotransmitter) levels decrease. Since dopamine can control your body movement, it makes it hard to balance, and you're usually stiff. It usually begins with a tremor in your hand.
Epilepsy: Epilepsy is a neurological disorder where neuron activity in the brain gets disturbed, resulting in a seizure. Epilepsy is usually genetic or gained through a trauma or stroke (brain injuries). During these seizures, people often lose consciousness. Most epileptic people are sensitive to lights (flashing and flickering especially).
Stroke: A stroke occurs when your blood supply to your brain is interrupted/stopped. This is a SERIOUS emergency. Cells can die from lack of blood and the resulting lack of oxygen. Most warning signs of a stroke include: numbness + weakness, trouble speaking, loss of balance, and dizziness.

Why does water have a strong surface tension and why is this important?
The stronger the cohesive force, the stronger the surface tension. The water molecule has two hydrogen atoms bond to an oxygen atom through covalent bonding. ... Formed bonds are called hydrogen bonds which lead to strong cohesive forces between the water molecules and high surface tension of water.
Why is it important?The surface tension of water provides the necessary wall tension for the formation of bubbles with water. The tendency to minimize that wall tension pulls the bubbles into spherical shapes. Surface tension and droplets: Surface tension is responsible for the shape of liquid droplets.
does the moon make it's own light? explain how the moon gives us light at night?
Answer:
The moon doesn't produce its own light. Moonlight is actually sunlight that shines on the moon and bounces off. In other words, its surface reflects light from the sun.The perceived brightness of the moon from Earth depends on where the moon is in its orbit around the planet.

Answer:
glycine and proline
Explanation:
First, a three-dimensional stranded structure is assembled, with the amino acids glycine and proline as its principal components. This is not yet collagen but its precursor, procollagen. Procollagen is then modified by the addition of hydroxyl groups to the amino acids proline and lysine.

Heating a gas increase its viscosity .When the viscosity of a fluid decreases,it's flow rate increase. You can compare the viscosity of different fluids by comparing their flow rate. Flow rate is affected by adhesion and cohesion. The slower the fluid flows ,the greater the viscosity.
what percentage of genetic information is passed on from parents to their offspring
Answer:
50% from each parent
Explanation:
The percentage of genetic information passed on from parents to their offspring is 50% from each parent, for a total of 100%.
What is the percentage of genetic information?Approximately 50% of genetic information is passed on from each biological parent to their offspring. This occurs through the combination of genetic material during fertilization, where half of the offspring's genetic material comes from the mother and the other half from the father.
However, the exact percentage of genetic information passed on can vary due to factors such as genetic mutations and recombination during meiosis.
This occurs through the process of sexual reproduction, where each parent contributes one gamete (sperm or egg) containing half of their genetic information.
When the sperm and egg combine during fertilization, they form a zygote with a complete set of genetic information (100%), half from each parent.

Explanation:
Visible light ranges from low blue to far-red light and is described as the wavelengths between 380 nm and 750 nm, although this varies between individuals. The region between 400 nm and 700 nm is what plants use to drive photosynthesis and is typically referred to as Photosynthetically Active Radiation (PAR).
