What will most likely result after a fire or other natural disaster damages?

What will most likely result after a fire or other natural disaster damages an ecosystem in a certain area? … An ecosystem similar to the original one will eventually be reestablished if the climate is stable.

Which organ system processes organic molecules so they can enter cells?

The digestive system uses mechanical and chemical methods to break food down into nutrient molecules that can be absorbed into the blood. Once in the blood the food molecules are routed to every cell in the animal’s body.

Which statement best describes the relationship between the number of genes and the number of chromosomes in human skin cells?

Which statement best describes the relationship between the number of genes and the number of chromosomes in human skin cells? There are more genes than chromosomes in skin cells.

Which statement best describes what happens to energy and molecules in a stable ecosystem?

Which statement best describes what happens to energy and molecules in a stable ecosystem? Energy is continuously added to the ecosystem and molecules are recycled.

What would most likely occur after an ecosystem is disrupted by fire?

What would most likely occur after an ecosystem is disrupted by fire? The ecosystem would eventually return to its original state.

What usually results when an organism maintains homeostasis?

When an organism fails to maintain homeostasis the organism typically becomes ill and it will die if homeostasis cannot be achieved.

What are the 4 major groups of organic molecules involved in the metabolic process?

Organic compounds are larger more complex molecules that always contain carbon and hydrogen. The four major organic molecules that make up living organisms are: carbohydrates proteins lipids and nucleic acids. These larger molecules are synthesized from smaller building blocks.

What factor causes the DNA fragments to move in this technique?

To separate DNA using agarose gel electrophoresis the DNA is loaded into pre-cast wells in the gel and a current applied. The phosphate backbone of the DNA (and RNA) molecule is negatively charged therefore when placed in an electric field DNA fragments will migrate to the positively charged anode.

Which statement best describes the relationship between protein amino acids and DNA?

Both nucleic acid and protein they have four biomolecules which are common in both of them. The major relationship between protein and nucleic acid is the reproduction of DNA which contains the information on how cells are used together with RNA which helps to make protein.

Which statement best describes relationship between cells DNA and proteins?

(1) Cells contain DNA that controls the production of proteins. (2) DNA is composed of proteins that carry coded information for how cells function. (3) Proteins are used to produce cells that link amino acids together into DNA.

Which one of the following statements best describes the relationship between cells DNA and proteins?

Which statement best describes the relationship that exists among proteins DNA and cells? Proteins are made up of DNA which determines the cells that are produced. DNA is made up of proteins which tell a cell how to function. Cells contain DNA which controls the production of proteins.

What happens to energy and molecules in an ecosystem?

As energy moves through an ecosystem it changes form but no new energy is created. Similarly as matter cycles within an ecosystem atoms are rearranged into various molecules but no new matter is created. So during all ecosystem processes energy and matter are conserved.

Which organism carries out autotrophic nutrition?

plants
Organisms such as plants algae & some bacteria which make their own food from light energy are called autotrophs. Photosynthesis occurs within the chloroplasts of plant cells. The green pigment that captures the sun’s energy is chlorophyll.

What is the sequence of amino acids in a protein most directly dependent on?

Number of codons in mRNA.

What would most likely happen to the new stable ecosystem in future years if no further disruptions occur?

Some energy is used by the organisms at each level and is not available to the organisms at the next level. Stable predator-prey relationships are necessary to maintain a healthy ecosystem. … If no further disruption occurs to the new stable ecosystem it will remain a stable ecosystem.

Which condition would cause an ecosystem to become unstable?

Removal of native species. Introduction of new species. Pollution toxification of an area.

Which sequence shows a correct flow of energy through an ecosystem?

food chain
A food chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another the levels in the food chain are producers primary consumers higher-level consumers and finally decomposers. These levels are used to describe ecosystem structure and dynamics.

How do organisms maintain cellular and molecular balance?

Homeostasis in an organism or colony of single celled organisms is regulated by secreted proteins and small molecules often functioning as signals. Homeostasis in the cell is maintained by regulation and by the exchange of materials and energy with its surroundings.

When an organism fails to maintain homeostasis The most likely result is?

When the cells in your body do not work correctly homeostatic balance is disrupted. Homeostatic imbalance may lead to a state of disease. Disease and cellular malfunction can be caused in two basic ways: by deficiency or toxicity.

What is maintained by homeostasis?

Homeostasis refers to the body’s ability to maintain a stable internal environment (regulating hormones body temp. water balance etc.). … From body temperature to blood pressure to levels of certain nutrients each physiological condition has a particular set point.

What atoms make up carbohydrates?

Carbohydrates contain only carbon hydrogen and oxygen atoms prior to any oxidation or reduction most have the empirical formula Cm(H2O)n. Compounds obtained from carbohydrates by substitution etc. are known as carbohydrate derivatives and may contain other elements.

What are the 3 stages of metabolism?

Catabolism: The Breakdown
  • Stage 1: Glycolysis for glucose β-oxidation for fatty acids or amino acid catabolism.
  • Stage 2: Citric Acid Cycle (or Kreb cycle)
  • Stage 3: Electron Transport Chain and ATP synthesis.

Which is a function of a protein macromolecule?

Types of biological macromolecules
Biological macromolecule Building blocks Functions
Proteins Amino acids Provide cell structure send chemical signals speed up chemical reactions etc
Nucleic acids Nucleotides Store and pass on genetic information

How do DNA molecules move in relation to charge?

DNA is negatively charged therefore when an electric current is applied to the gel DNA will migrate towards the positively charged electrode. Shorter strands of DNA move more quickly through the gel than longer strands resulting in the fragments being arranged in order of size.

Why do smaller fragments of DNA move faster?

Because all DNA fragments have the same amount of charge per mass small fragments move through the gel faster than large ones.

Why does DNA move towards the anode in gel electrophoresis?

Answer : Generally a DNA fragment contains phosphate groups which have a negative charge. Hence DNA fragments are negatively charged thereby moving towards anode under the influence of an electric field during gel electrophoresis.

Which statement best describes some protein molecules in a cell?

Which statement best describes some protein molecules in a cell? Proteins are long folded chains that can form various cell parts. Proteins are composed of four different starches that direct cell activity.

What is the order of molecules involved in protein synthesis?

It includes three steps: initiation elongation and termination. After the mRNA is processed it carries the instructions to a ribosome in the cytoplasm. Translation occurs at the ribosome which consists of rRNA and proteins.

Which statement best describes the molecular structure of protein along?

Which statement best describes the molecular structure of protein along with one of the functions of proteins? It is a straight chain hydrocarbon that can help fight disease. It is a complex folded chain that helps regulate cell processes.

Which factor most affects the order of amino acids in protein?

The sequence of a protein is determined by the DNA of the gene that encodes the protein (or that encodes a portion of the protein for multi-subunit proteins). A change in the gene’s DNA sequence may lead to a change in the amino acid sequence of the protein.

What will most likely happen if there is a change in the base sequence of this molecule?

What will most likely happen if there is a change in the base sequence of this molecule? 1) The molecule will be converted into an inorganic compound. The amino acid sequence may be altered during protein synthesis.

What organelle controls what comes in and out of the cell?

Membrane
