There are three stages in the life cycle of a spider : - the first is embryonic stage, then the larval stage and finally nympho- imginal stage.
Answer Choices:
DNA provides the energy needed for an organism to grow and function
DNA is copied into mRNA, which controls cellular functions
DNA codes for proteins, which allow an organism to grow and function
DNA unzips and each strand codes for a different amino acid
Answer:
DNA codes for proteins, which allow an organism to grow and function
Explanation:
DNA provides the energy needed for an organism to grow and function - this is false. DNA does not provide energy. A molecule called ATP, mostly produced by cellular respiration, provides energy for the cells to grow and function.
DNA is copied into mRNA, which controls cellular functions - this is false. While it is true that DNA is copied into mRNA, mRNA does not directly control cellular functions. Instead, mRNA is translated into proteins.
DNA codes for proteins, which allow an organism to grow and function - <u>this is true, as indicated above, DNA is transcribed to mRNA which is translated into proteins. Proteins carry out essentially all the functions in the cell</u>
DNA unzips and each strand codes for a different amino acid - this is false, DNA is transcribed into mRNA. Each mRNA codon (three bases) codes for a different amino acid
Explanation:
The division comprises a tremendous diversity of plants among its four subgroups: psilopsids, leafless and rootless primitive forms commonly known as whisk ferns (though not true ferns); sphenopsids, feathery leaved plants commonly called horsetails; lycopsids, low-lying plants called club mosses; and pteropsids,
Answer:b compound microscope
Explanation:
I believe that the amount of carbon stored in organisms decreases as you move up the food chain. This is because carbon constitutes the biomass of an organism which decreases as you move upward the food chain. Each link in a food chain is known as a trophic level. Trophic levels represent a feeding step in the transfer of energy and matter in an ecosystem. Biomass is the amount of organic matter comprising a group of organisms in a habitat. As you move up a food chain, both available energy and biomass decrease. Energy is transferred upwards but is diminished with each transfer from one trophic level to the next.
