1. Calcium carbonate minerals are the building blocks for the skeletons and shells of mini marine organisms. It is important to ocean creatures because they make their shells out of this material. Examples of animal products that are primarily of calcium carbonate include seashells, egg shells, pearls, and notably coral

1a: Calcium carbonate is a dietary supplement used when the amount of calcium taken in the diet is not enough.
1b: Oceans are an important source of food. They host 80 percent of the planet's biodiversity, and are the largest ecosystem on Earth.

2: Carbon dioxide (CO2) emissions from burning fossil fuels are making the world's oceans more acidic. In the water, CO2 reacts to form carbonic acid, and over the years, the ocean's acidity has increased by 30 percent because so much of the excess man-made CO2 is being drawn into the water.

3: Global warming is the long-term heating of Earth's climate system observed since the pre-industrial period (between 1850 and 1900) due to human activities, primarily fossil fuel burning, which increases heat-trapping greenhouse gas levels in Earth's atmosphere.

Mitosis and meiosis are processes involved in cellular reproduction. Which of the following describes an event that results from

forsale [732]

The event that results from mitosis but not from meiosis is: C) daughter cells that are identical to the parent cell.

Mitosis is the process of cell division where a parent cell divides to form two daughter cells. These cells have the same number of chromosomes as that of their parent and that is the reason why the process is also known by the name equational division.

Meiosis is the process where a cell divided into 4 daughter cells and they have half of the total number of chromosomes as that of their parent. Thus is why the process is also called reductional division. Meiosis does not occur in the somatic cells of the body but in the germ cells.

which of the following is an example of epithelial tissue? A) Bone B) Skin C) Fat D) Muscle User: which of the following tissue

lions [1.4K]

<span>Answer B, skin, is an example of epithelial tissue. All other answer are examples of different types of tissue; Bone being osseous tissue, fat being connective tissue and muscle being muscle tissue. Nervous tissue is one of the types that has cells that expand across the entire human body. Nerves can be both long and reach every corner of the body. The other type of tissue that can cross the entire body is epithelial. This type of tissue does not produce large cells that span great distances on/in the body. But, these cells do provide the lining throughout the body and are the tissue that makes up the protective layer called skin. Both connective tissue and muscle tissue form large amounts of tissue in the body but they do not expand to all reaches of it.</span>
