What is the purpose using lime water in release of carbon dioxide experiment
Limewater can be used to detect carbon dioxide. If carbon dioxide is bubbled through limewater then it turns from clear to cloudy/milky in color. This is why limewater used in a simple respirometer can show that more carbon dioxide is present in exhaled air compared to inhaled air.

Sand dunes along the coast are formed of bare sand. Eventually, grasses take root on the dunes. Over
time, larger plants such as shrubs and trees are able to grow at the edge of the sand dune ecosystem.
This gradual change in plant communities of a sand dune ecosystem can result in -
A- reduced symbiotic relationship between producers and bacteria
B- reduced energy absorption by consumers
C- greater erosion rates
D- greater species diversity
The gradual change in plant communities of a sand dune ecosystem is an example of ecological succesion and can result in greater species diversity.
What is ecological succession?Ecological succession refers to the gradual changes that occurs in a habitat such that with time new species replace previous species or new species take over an envrionment that had no living organisms initially until a stable community of organisms is established.
There are two types of ecological succession;
primary succession secondary successionSuccession results in greater species diversity.
An example of succession is when species of organisms begin to live one previously care area such as in sand dunes.
Therefore, the gradual change in plant communities of a sand dune ecosystem can result in greater species diversity.

In general, excess amounts of water-soluble vitamins are excreted via the urine.
Water-soluble vitamins are generally excreted through the urine. Water-soluble vitamins can easily combine with the urine and be excreted out of the body. Hence, they need to be taken on a regular basis.
What are vitamins?
Vitamins are necessary for the body as they play an important role in enzyme activity. Fat-soluble vitamins, such as vitamins A, D, E, and K, are present, and water-soluble vitamins, such as the vitamin B complex and vitamin C, are also present. Fat-soluble vitamins can be stored in body fat and used, but water-soluble vitamins can be lost through urine.
Water-soluble vitamins can be gotten from fruits such as oranges, etc. To avoid vitamin deficiency, they should be taken on a regular basis as they are lost. Vitamin C is important for collagen function. Fat-soluble vitamins can be gotten from plants and animals.

Explanation:
Hope this helps!
Eukaryotes has been known as the creatures which are made up of the cells with membrane-bound organelles and the nucleus that contains DNA in the manner of chromosomes. Thus, option B is correct.
What are eukaryotes and prokaryotes?Prokaryotes and eukaryotes are the two classes into which all living things may be divided based on the basic makeup of their cells. Prokaryotes - smaller, usually bacteria, unicellular, NO membranes and Eukaryotes has the membranes, and the complex organelles, plant or animal cells.
Prokaryotes are the creatures that consisting of the cells that don't have the cell nuclei or any organelles that are enclosed in the membranes. It follows that prokaryotes' DNA is not contained within a nucleus.
Eukaryotic organisms can have several cells or only one cell. Eukaryotes make up all animal life. Protists, fungi, and plants are examples of additional eukaryotes.
