A hurricane causes a stream to overflow its banks.
Increased wind increases water evaporation from a plant.
Answer: Water pollution causes a decrease in fish populations in a river.
Explanation:
An ecosystem is a biotic community which includes abiotic (non-living) and biotic (living) components. The abiotic components includes water, sunlight, wind, soil and temperature whereas the biotic components includes the living beings such as plants, animals, microbes and other. The dynamic equilibrium of the ecosystem can be defined as the condition in which the abiotic factors of the ecosystem supports the life of the biotic factors without undergoing any drastic change which could negatively affect the population of living beings.
The river water is an abiotic factor which can be a habitat of large diversity of marine flora and fauna. The pollution of water could negative affect the population of the fish residing in the river. This will disturb the balance of ecosystem. As, in the ecosystem various species interact with one another to survive. Hence, the dynamic equilibrium will be changed.
Answer:
The backbone of the double helix is made up of SUGAR molecules and PHOSPHATE groups, and the two chains are joined together by hydrogen bonds between the NUCLEOTIDE BASES
Explanation:
DNA is a double helix structure. It looks similar to a twisted ladder. The backbone is like the sides of the ladder. They are made up of sugar molecules called deoxyribose and phosphate linked together. The nucleotide bases make up the rungs. Each rung is made up of 2 complimentary bases that are held together by hydrogen bonds.
The backbone of the double helix is made of sugar-phosphate molecules and groups. The two chains are joined by hydrogen bonds between the nitrogenous bases. These bases are adenine (A), thymine (T), cytosine (C), and guanine (G)
The backbone of the double helix, such as DNA, is made up of sugar-phosphate molecules and sugar-phosphate groups, and the two chains are joined together by hydrogen bonds between the nitrogenous bases
More specifically, the sugar is deoxyribose, and the phosphate group is a component of each nucleotide. The strands of the helix run in opposite directions, making them antiparallel. The nitrogenous bases that join the two strands are adenine, thymine, cytosine, and guanine - adenine always binds with thymine and cytosine with guanine.

c. variation
b. over production of offspring
d. all of these
The answer is a. natural selection.
In natural selection, genotype variations that will increase the chance of survival and reproduction of some organism are preserved and will be inherited. Darwin's theory suggested that there are variations among individuals in a population and that these variations will help individuals to survive. According to Darwin, natural selection is the only factor that affects frequency of different variations.

how do organisms with many cell types develop from a single cell
Answer:
A multicellular organism develops from a single cell (the zygote) into a collection of many different cell types, organized into tissues and organs.During development, cells use both intrinsic, or inherited, information and extrinsic signals from neighbors to "decide on" their behavior and identity.
