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

In 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 D is one of the principal factors involved in calcium regulation. Vitamine D helps to double calcium absorption through the thin intestine.

During 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

Elder 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.

Many 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.

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.

Answer:

Animals breathe the carbon dioxide released by plants after photosynthesis. And  animals use the plants’ chlorophyll to make their own food.

Explanation:

Animals breathe the carbon dioxide released by plants after photosynthesis is the way by which animals rely on plants. The correct option is B.

Thus, In the ecosystem of the Earth, photosynthesis is an essential process. It serves as the primary source of energy for plants, which are ultimately ingested by herbivores.

This energy is then transferred up the food chain to higher-level consumers.

Aerobic respiration, the mechanism through which mammals and other creatures produce energy by mixing oxygen with glucose, depends on the oxygen created during photosynthesis.

Thus, Animals breathe the carbon dioxide released by plants after photosynthesis is the way by which animals rely on plants. The correct option is B.

Answer:In the central nervous system, the supporting cells are collectively referred to as neuroglia.

Explanation:In the central nervous system, the supporting cells are collectively referred to as neuroglia.

Supporting cells of the nervous system are collectively called neuroglia or glia. These are non-neuronal cells that perform a number of functions in the nervous system, such as protecting and supporting neurons, feeding neurons, and clearing the nervous system of waste products.

The correct operation of the neurological system depends on the glia. They shield and protect neurons, clear waste products from the nervous system, and contribute to the nervous system's immunological response.

Glia is necessary for neurons to function effectively, which in turn allows the nervous system to operate normally.

Answer:

carbon because its EC is 2:4 and the diagram shows 4electrons in its outer shell

The speed of the wave will be 0.026 m/s

The speed of a wave is the distance traveled by a given point on the wave (such as a crest or trough) in a given interval of time.

Speed is given by the formula

[tex]Speed = \frac{Distance}{Time}[/tex]

From the question,

Distance = 8.5 cm

First, convert this to meter

Recall:

100cm = 1m

∴ [tex]8.5 cm = \frac{8.5}{100}[/tex] m

8.5 cm = 0.085m

and

Time = 3.25 seconds

Now, putting the above parameters into the equation

[tex]Speed = \frac{Distance}{Time}[/tex]

∴ [tex]Speed = \frac{0.085}{3.25}[/tex]

Speed = 0.026 m/s

Hence, the speed of the wave will be 0.026 m/s

Answer:

2)  H3PO4

Explanation:

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.

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.

Answer:

The tonicity will result in the following: no net movement of water (isotonic), net flow of water out of a cell (hypertonic), or net flow of water into a cell (hypotonic). Two solutions that are isosmotic may not be isotonic. ... In the case of red blood cells, this is referred to as hemolysis (4).
