Answer:
Chemical weathering
Explanation:
Caves are formed by the dissolution of limestone. Rainwater picks up carbon dioxide from the air and as it percolates through the soil, which turns into a weak acid. This slowly dissolves out the limestone along the joints, bedding planes and fractures, some of which become enlarged enough to form caves.
Chemical weathering involves the decomposition of rocks due to chemical reactions between minerals such as calcite with water and gases in the atmosphere (e.g. carbon dioxide and sulphur dioxide). The solution of soluble minerals is particularly important in limestone landscapes.
Solutional caves or karst caves are the most frequently occurring caves. Such caves form in rock that is soluble; most occur in limestone, but they can also form in other rocks including chalk, dolomite, marble, salt, and gypsum.
Essentially, water reacts with carbon-dioxide to form carbonic acid. It then seeps slowly through the roof of the cave, depositing calcium carbonate, which hardens and builds up over time to form a stalactite.
D. Fertilized egg
A zygote is a cell which is a diploid cell in the combination of the spem and egg cell. Furthermore, this cell which came from the parent cell was successfully fertilized at the fallopian tube of the female reproductive system.
A zygote will develop to become an embryo for the next few weeks.
Answer:
Inheritance Patterns
Explanation:
Mendel was studying how genes are past on to future generations and in what circumstances this can occur. He used pea plants as they multiply and grow quickly allowing him to observe many generations much faster than he would be able to observing humans or even other mammals. He also used pea plants because this way he could control reproduction of his pea plant population to adjust to specific questions he had in terms of his research.
Answer:
Explanation:Dendrites are the segments of the neuron that receive stimulation in order for the cell to become active. They conduct electrical messages to the neuron cell body for the cell to function
