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-----------------------------------------------

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.

you will know that it still crenated
The only way to tell if the red blood cells are crenated is to observe them under a microscope
What is crenation?Crenation is the process of red blood cells becoming misshapen and breaking apart, and this can be seen through the examination of red blood cells under a microscope.
By observing the shape of the red blood cells, it can be determined if they are crenated or not. Additionally, other methods such as hemoglobin analysis or measuring the osmotic fragility of the red blood cells can also be used to determine if crenation has occurred.

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.
Explanation:
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.

Effects of temperature on brooding of chicks
Answer:
In research studies where groups of chicks were brooded at either 80 degrees F or 90 degrees F, the chicks reared under the warmer temperature had better weight gains, feed conversion and livability. Chicks brooded under 80 degrees F experienced reduced growth compared to the high brooding temperature treatment.

According to Kepler's second law of motion, which statement describes the area
swept out py a line between a planet and the sun?
It is constant if the planet moves at a constant speed.
O It increases as the planet moves away from the sun.
O It is constant for equal times.
OIt increases as the planet approaches the sun.
Answer: It is constant for equal times
Explanation: Just did the assignment
According to Kepler's second law of motion it is constant for equal times. The correct option is C.
What is Kepler's law?Kepler's laws of planetary motion, published between 1609 and 1619 by Johannes Kepler, characterize the orbits of planets around the Sun.
The speed of a planet in an elliptical orbit around the Sun is described by Kepler's second law of planetary motion.
It states that a line drawn among both the Sun as well as the planet shuffles equivalent regions in equal amounts of time.
As a result, the planet's speed increases as it approaches the Sun and declines as it fades away from it.
Kepler's laws of planetary motion represent a watershed moment in the transformation from geocentrism to heliocentrism.
They establish the first quantitative link among the planets, together with Earth. They also represent a time when the important questions of the day were changing.
Thus, the correct option is C.

What the relationship between a glucose molecule and the products it makes during cellular respiration.
Answer:
During cellular respiration, a glucose molecule is gradually broken down into carbon dioxide and water. Along the way, some ATP is produced directly in the reactions that transform glucose. Much more ATP, however, is produced later in a process called oxidative phosphorylation.
During cellular respiration, glucose makes water, carbon dioxide, ATP, lactic acid, and ethanol. In the absence of oxygen, ethanol and lactic acid are formed from the glucose.
What is glycolysis?
Glycolysis is a process in which glucose breaks down inside a cell. Glucose makes pyruvate as an end product in this process. In the presence of oxygen, glucose breaks down into pyruvate and proceeds to the Krebs cycle. In this process, ATP, water, and carbon dioxide are released.
In the absence of oxygen, glucose is converted into lactic acid and ethanol. This is called fermentation and produces only 2 ATP from glucose. This is called anaerobic respiration.
When oxygen is present from glucose, nearly 36-38 ATP are formed. Pyruvate converts into acetyl CoA, and it enters the Krebs cycle. A complete oxidation of glucose takes place in the presence of oxygen.
Hence, in the presence of oxygen, 36-38 ATP is released from glucose, and in the absence of oxygen, lactic acid and ethanol are produced with 2 ATP.
