<u>Answer</u>:
Concave shape of the wave rock is a physical evidence that supports the evolution of earth due chemical weathering
<u>Explanation</u>:
It is the best physical evidence of collection in the earth’s evolution. The earth surface is 2.7 billion years old, also the basis for formation of Australian continent formation. The wave rock is formed by weathering of the surrounding area, which helps in proving the deposition part, as the wave rock was below the ground, occurred due to deposition of rock years over years. It is made from very tough material from its surrounding. The weathering reduced the surrounding terrain, while the bedrock remained to witness for the history.
Answer:If a DNA double helix is 100 nucleotide pairs long and contains 25 adenine bases, how many guanine bases does it contain? Well, we have to know the base pairs for DNA first. Adenine only bonds with thymine with two hydrogen bonds, while guanine only bonds with cytosine with three hydrogen bonds. Bonding pairs can also happen vice-versa.

1. Animals depend on plants to keep them alive is Plants are producers they take energy from the sun, nutrients from the earth, and water to grow and have their flowers, seeds, and berries.
They also release oxygen, which all animals, including humans, need to stay. Animals are consumers and they all depend on plants for survival.
2. carbon dioxide and water reach the chloroplasts in leaves is Basically the roots consume the water and transports it up the xylem, which gets it to the leaves. Carbon dioxide contacts the chloroplasts in the leaves via a stomata
3. Two pieces of evidence that show that plants cannot make their own food without light. When plants lack light, they don't deliver chlorophyll (the green pigment in plants), and plants can turn pale green to yellow to white. Plant stems become “leggy,” meaning stems become long and thin and appear to be advancing toward the source of light.
- The photosynthesis is the only method for synthesizing food. It is commonly believed that about 717.6Kcal energy is required to prepare just 10g of glucose. No energy input no metabolism and therefore no food.
<h3>How are leaves tested for starch?</h3>
The existence of starch in leaves can be tested by the Iodine test. When we remove chlorophyll from the leaf by cooking it in alcohol and then placing two drops of iodine solution, it is a color change to blue indicates the existence of starch.

Answer:
secretion
Explanation:
Epithelial cells are usually cells located or found outside the body, skin, urinary tract, vessels, cavities, and organs of the body, and have special modifications of their surfaces which depends upon the specific roles they perform and where they are found. However, many types of epithelial cells perform a common function of secretion. Epithelial cells are closely packed together.
