What will most likely result after a fire other natural disaster damages an ecosystem in a certain area?

What will most likely result after a fire other natural disaster damages an ecosystem in a certain area?

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

Which cellular change in an organism could be inherited by the next generation *?

This is due to the fact that a baby is created from the fusion of an egg and sperm. Therefore, choice 2, the deletion of a single DNA base in a sperm cell of a trout, is the correct answer.

Which structure is responsible for the synthesis of ATP Regents?

Mitochondria produce energy through cellular respiration, they use glucose extracted from food in order to form ATP. Explanation: Mitochondria produce energy through cellular respiration, they use glucose extracted from food in order to form ATP.

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.

How does forest fire affect the ecosystem?

It plays a key role in shaping ecosystems by serving as an agent of renewal and change. But fire can be deadly, destroying homes, wildlife habitat and timber, and polluting the air with emissions harmful to human health. Fire also releases carbon dioxide—a key greenhouse gas—into the atmosphere.

How does natural selection affect populations?

Individuals that develop beneficial traits have a better chance of survival and individuals with less useful traits are weeded out through the process of natural selection. The greater the variety of traits that exist in a population, the greater the population’s chance of survival.

How does natural selection affect populations Regents?

It increases competition between populations that occupy different niches, increasing the chance of extinction of the less-adapted species.

Which structure is responsible for the passage of materials into and out of the cell?

Cell membrane
Cell membrane It maintains the integrity of a cell and controls passage of materials into and out of the cell. All materials within a cell must have access to the cell membrane (the cell’s boundary) for the needed exchange. The cell membrane is a double layer of phospholipid molecules.

What substance is directly involved in cellular communication within the human body?

B) cells to communicate with each other Acetylcholine is a chemical secreted at the ends of nerve cells. This chemical helps to send nerve signals across synapses (spaces between nerve cells). After the signal passes across a synapse, an enzyme breaks down the acetylcholine.

Which condition would cause an ecosystem to become unstable?

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

What type of disturbances would create a primary succession situation in an ecosystem?

Examples of disturbances that cause primary succession include retreating glaciers, volcanic eruption and the erosion of sand dunes. Human activity can also be a cause of primary succession, such as the creation of a paved surface. These types of disturbances leave bare rock exposed or otherwise accessible.

How does the fire affect the process of succession?

A classic example of secondary succession occurs in oak and hickory forests cleared by wildfire. Wildfires will burn most vegetation and kill those animals unable to flee the area. Thus, even when areas are devoid of life due to severe fires, the area will soon be ready for new life to take hold.

How does ultraviolet radiation affect the growth of a tree?

Ultraviolet radiation changes the DNA sequence within the gametes of some flowers of the tree. An increase in temperature reduces the number of cell divisions in the roots. Rapidly growing cells just under the bark are exposed to radiation, causing changes in genetic material.

Which is process is least likely to add to variety of traits in a population?

Which process is least likely to add to the variety of traits in a population? Genes involved in the production of abnormal red blood cells have an abnormal sequence of Down syndrome is a genetic disorder caused by the presence of an extra chromosome in the body cells of humans.

How are the evolutionary relationships of plants determined?

Scientists attempted to determine the evolutionary relationships between three different plant species, A, B, and C. In order to do this, they examined the stems and DNA of these species. Diagram 1 represents a microscopic view of the cross sections of the stems of these three species.

When is a new inheritable trait is expressed?

Event C: a new inheritable trait is expressed in an organism Event D: an mRNA strand with a new sequence of bases is synthesized DNA samples were taken from three different species and used to determine the amino acid sequence for a portion of a particular protein.
