Eating Vitamin D enriched foods,  Infancy , pregnancy increases calcium absorption.

Oxalic acid in spinach, Having a high fiber diet rich in phytic acid, being over 70 years old can decrease calcium absorption.

Why is Calcium absorption important?

It's crucial to have enough calcium in the blood that carries nutrients to the bones in order to avoid the loss of bone mass. Although milk and other dairy products are a great source of calcium, as we become older, our bodies require more calcium. Because many people stop consuming calcium-rich foods or beverages, like whole milk, due to dietary concerns, a calcium-rich dietary supplement is crucial. A daily calcium requirement of 1,200 mg is necessary for older persons.

Mitochondria and chloroplasts
Grace [21]

Answer:

C. prokaryotic cells

Definitions

The Mitochondrion is an organelle in the cytoplasm of cells that functions in energy production.

Chloroplast is usually defined as a plastic containing chlorophyll.

Chlorophyll is the green coloring matter of leaves and plants, essential to the production in a bluish-black form, C55H72MgN405 (chlorophyll a), and a dark-green form, C55H70MgN4O6 (chlorophyll b).  

A root cell is one of the maestro cells in the human organic structure that has possible ability of turning into any of the more than the organic structure's 200 cell types.  

Prokaryotes is any cellular organism that has no nuclear membrane, no organelles in the cytoplasm except ribosomes, and has its genetic material in the form of single continuous strands forming coils or loops, characteristic of all organisms in the kingdom Monera, as the bacteria and blue-green algae.

<h2>What are the similarities and differences between prokaryotes, mitochondria, and chloroplasts?</h2>

Both mitochondria and heterotrophic prokaryotes, as well as chloroplasts and autotrophic prokaryotes, have a genetic structure (DNA with a circular double helix shape and the genes themselves), as well as comparable ribosome types. In reality, the endosymbiotic idea is based on these parallels.

Which structure forms as DNA unwinds? A. a special marker B. a complementary base C. a replication bubble D. a double helix
kozerog [31]

A replication bubble forms as the DNA unwinds.

Option C  

<u>Explanation</u>:  

Replication bubble is the space where the strands of double helical DNA structure are separated with the help of DNA helicase. The strands of the double helical DNA are still in the helix form on the both end of the unwinded DNA stand which gives this region an appearance of a bubble.

DNA unwinding is the first step in replication or transcription of the DNA molecule. DNA helicase separates the two types of "DNA" that are connected by hydrogen bonds with the help of ATP hydrolysis.
