Answer:
Turtles hide their heads in their shells for protection. (behavioural adaptation)
camels have long eyelashes to protect their eyes from sand. (structural adaptation)
humans sweat to maintain a constant body temperature. (physiological adaptation)
Answer:
1. chromosome: tight coils of DNA
2. Eukaryote: a cell that has a membrane-bound nucleus
3. Gene: a specific sequence of DNA nucleotides that carry hereditary traits
4. Prokaryote: a cell whose nucleus is not bound by a membrane
5. Trait: genetic characteristic of an individual
Explanation:
Chromosomes are the thread-like structures that appear during cell division. Each chromosome is made up of DNA tightly coiled with its packing proteins.
A cell is defined as eukaryote or prokaryote on the basis of the presence of a membrane-bound nucleus. The cells that lack the membrane-bound nucleus and other membrane-bound organelles are called prokaryotic cells. Example: bacteria.
The cells that have a membrane bound nucleus in which DNA is present are called eukaryotic cells. Example: Plant cells.
A stretch of DNA that code for a particular protein and thereby regulate specific genetic trait is called a gene. Genes are present on chromosomes and are carried from one generation to next to maintain the genetic traits.
The features of living beings regulated by the gene are called trait. Example: skin color, eye color, etc.
Answer:
The correct answer is A)
To limit the potential flooding damage that could result if an earthquake happens and the dam spills over
Explanation:
According to the text, seismic risks are very high for dams in that region. One of the reasons is that some of the dams were built many years ago when civil engineers didn't have information about what an earthquake could do to dams.
Citing an occurrence that happened in 1899 as an example where thousands of people were killed as a result of a failed dam, it is feared that should same reoccur, the loss may be more because about 300,000 people occupy the flood zone along the Alameda Creek below the dam.

The water cycle is a system that shows how the water moves around in different states to transport itself. It uses different states which show a different transportation such as evaporation or condensation. The water cycle can also use continuous movement above and below the earths surface. There are five main steps to the water cycle which are evaporation, condensation, precipitation, transpiration, and runoff but there are still many more.
Hope this helps! :)
Glucose is converted into ATP because it is usable energy. Glucose is stored energy
