Reservoirs which provide humans, animals, and plants with drinkable water are lakes, rivers, and groundwater.

A reservoir is an enlarged lake behind a dam. Such a dam may be either artificial, built to store fresh water or it may be a natural formation.

All basic functions of a reservoir can be made use of: storage, water conservation, flood control, water treatment, and aquatic environment. Reservoir systems can be either single- or multi-purpose systems.

A dam and reservoir may support navigation, recreation, flood control, irrigation, and water supply, with each multipurpose benefit providing significant social and economic impacts on a local, regional, and national level.

Answer:

This question lacks options, the options are:

A. The sequence of DNA determines the structure of lipids, which produce phenotypes.

B. The sequence of DNA determines the structure of proteins, which produce phenotypes.

C. The sequence of DNA determines the structure of phosphates, which produce phenotypes.

D. The sequence of DNA determines the structure of carbohydrates, which produce phenotypes.

The answer is B.

Explanation:

DNA is the genetic material found in the genome of living organisms. DNA holds the information needed for the synthesis of useful products in an organism. DNA contains segments called GENES that encodes the biological molecule, PROTEINS, which is responsible for the trait exhibited by organisms.

An example of trait in humans is human color, which is encoded by DNA. However, this DNA does not directly produce hair color in humans but the information held in it undergoes expression to produce protein called MELANIN, which is responsible for the hair color trait. Hence, the sequence of DNA determines the structure of proteins, which produce phenotypes (hair color).

Answer:

Composite, shield, cinder cones, and supervolcanoes are the main types of volcanoes.

Composite volcanoes are tall, steep cones that produce explosive eruptions.

Shield volcanoes form very large, gently sloped mounds from effusive eruptions.

Volcanoes have several shapes, which are controlled by the composition of the magma and the nature of its eruption. If a volcano produces very fluid lava (low in the compound SiO2, or silica), the magma flows a long distance before it cools, making a flat, shield-shaped volcano.

The phosphate groups allow the nucleotides to link together, creating the sugar-phosphate backbone of the nucleic acid while the nitrogenous bases provide the letters of the genetic alphabet. These components of nucleic acids are constructed from five elements: carbon, hydrogen, oxygen, nitrogen, and phosphorous.

Answer:

Producers

Producers are any kind of green plant. Green plants make their food by taking sunlight and using the energy to make sugar. The plant uses this sugar, also called glucose to make many things, such as wood, leaves, roots, and bark. Trees, such as they mighty Oak, and the grand American Beech, are examples of producers.

Primary Consumer

Within an ecological food chain, Consumers are categorized into primary consumers, secondary consumers, tertiary consumers. Primary consumers are herbivores, feeding on plants. Caterpillars, insects, grasshoppers, termites and hummingbirds are all examples of primary consumers because they only eat autotrophs (plants).

Secondary Consumer

Spiders, snakes, and seals are all examples of carnivorous secondary consumers. Omnivores are the other type of secondary consumer. They eat both plant and animal materials for energy. Bears and skunks are examples of omnivorous secondary consumers that both hunt prey and eat plants.

Decomposer

They include fungi along with invertebrate organisms sometimes called detritivores, which include earthworms, termites, and millipedes. Fungi are important decomposers, especially in forests. Some kinds of fungi, such as mushrooms, look like plants.

The transfer of pollen to a stigma, ovule, flower, or plant to allow fertilization. It can be transferred by things that feed from what has pollen. Self-pollination occurs when the pollen from the anther is deposited on the stigma of the same flower, or another flower on the same plant. Cross-pollination is the transfer of pollen from the anther of one flower to the stigma of another flower on a different individual of the same species.

Answer:

Proteins are one of the most abundant organic molecules in living systems and have the most diverse range of functions of all macromolecules. Proteins may be structural, regulatory, contractile, or protective; they may serve in transport, storage, or membranes; or they may be toxins or enzymes. Each cell in a living system may contain thousands of different proteins, each with a unique function. Their structures, like their functions, vary greatly. They are all, however, polymers of alpha amino acids, arranged in a linear sequence and connected together by covalent bonds.

Alpha Amino Acid Structure

The major building block of proteins are called alpha (α) amino acids.  As their name implies they contain a carboxylic acid functional group and an amine functional group.  The alpha designation is used to indicate that these two functional groups are separated from one another by one carbon group. In addition to the amine and the carboxylic acid, the alpha carbon is also attached to a hydrogen and one additional group that can vary in size and length.  In the diagram below, this group is designated as an R-group.  Within living organisms there are 20 amino acids used as protein building blocks.  They differ from one another only at the R-group position. The basic structure of an amino acid is shown below:

Figure 2.1 General Structure of an Alpha Amino Acid

There are a total of 20 alpha amino acids that are commonly incorporated into protein structures (Figure 2.x). The different R-groups have different characteristics based on the nature of atoms incorporated into the functional groups. There are R-groups that predominantly contain carbon and hydrogen and are very nonpolar or hydrophobic.  Others contain polar uncharged functional groups such as alcohols, amides, and thiols. A few amino acids are basic (containing amine functional groups) or acidic (containing carboxylic acid functional groups). These amino acids are capable of forming full charges and can have ionic interactions. Each amino acid can be abbreviated using a three letter and a one letter code.
