Why do duplicated cells need to be identical from the original cell? It is more difficult for the organism's body to create a ne

w and different cell New cells need to look and work the same way as the original cell Organisms need extra cells just in case their cells are harmed. Organisms need the new cells for change and growth.

Answer: Cells will duplicate or copy their DNA right before they divide. The process of cell division is called mitosis. Since the cell is dividing it needs two copies of its DNA - one is kept by the parent cell and the other is passed to the daughter cell.

When they (green sea turtles) eat algae, which biomolecule are they getting from it? A. Carbohydrate B. nucleic acid C. protein
Degger [83]

<u>Answer:</u>    A. Carbohydrate

<em>When green sea turtles eat algae they are getting carbohydrates from it. </em>

<u>Explanation:</u>

Different sea turtles have different diets. Some are omnivores while some are herbivores. Green sea turtles belong to the group of herbivorous sea turtles.  

<em>The diet of hatchlings is different from that of the adults. Hatchlings are omnivorous and feed on mollusks and crustaceans.</em> The adult sea turtles have to scrape off algae from rock surfaces and hence has a beak shaped like the teeth of a saw.

<em>Other type of sea turtles are loggerheads and leatherbacks that mainly feed on sponges and jellyfish respectively .</em>

Which ecosystem has more biodiversity EXPLAIN!
Gekata [30.6K]
The two richest ecosystems lie in tropical rainforests and coral reefs. On land, tropical rainforests contain many species variation with an abundance of species in bird, mammals, amphibians, and plants. While tropical rainforests occupy only 7 percent of the Earth’s land area, they contain over half of the world’s species. This may be because species richness tends to increase with decreased elevation, increasing solar exposure, and increased precipitation; that is, hot, rainy low-land areas have the most species. In contrast, deserts have low species variation because of low precipitation. On earth, water is majorly important the equation for life. Many of the species are genetically isolated because of habitat size and variation in the build of the land (mountains, equator location, etc) such as seen in the Galapagos islands and the Amazon rainforest, both near and in South America.

Hope this helps!

babymother [125]

Answer;

-Glycogen

The organic molecule called glycogen is formed of branched chains of sugar units.

Explanation;

-Glycogen is a branched polysaccharide of glucose that serves as a form of energy storage in humans, animals, fungi, and bacteria.

-In humans, glycogen is made and stored in liver and muscle cells. Muscle cell glycogen is broken down into glucose, and liver glycogen is broken down into glucose as a circulating energy source glucose for use by the body.

-Glycogen is accumulated in response to insulin and broken down into glucose in response to glucagon. It plays a major role in maintaining the blood-glucose levels, which is vital since some organs in the body such as the brain purely depend on glucose for energy.
