Name two possible causes of the largest mass extinction in Earth’s history and explain how this both helped and hurt different species.
Answer:
Explanation:
Two possible causes for the biggest mass extinction event in the history of our planet would be an asteroid impacting the planet and the massive volcanic activity. This mass extinction event is called the Permian-Triassic extinction. This helped many species emerge as survivors and thrive without the oppressive bigger species that died out. It hurt many species that were unable to survive the harsh conditions that resulted from everything that was happening to their habitats and food sources.
The different forms of a characteristic
Something, such as sunlight, causes a mutation in the genes of a cell. When that cell’s chromosomes copy themselves, the new chromosomes both have mutation. When the cells divide, both new cells carry the same mutation. Do you think this type of mutation can be passed to the offspring? Yes or No. Explain your answer
Answer:
yea
Explanation:
Answer:
Yes!
Explanation:
I believe that it can because it is in the Genes to be passed down to the offspring.
Explain how mitosis
maintains the chromosome number of the
original cells when forming new cells.
Mitosis is a type of cell division that helps to maintain the chromosome number of the original cells by dividing cells that previously duplicate their genetic material (DNA) during the interphase (S phase).
The cell cycle is divided into the interphase and the mitotic (M) phase.The interphase of the cell cycle is in turn divided into three different phases: Growth 1 (G1) phase, Synthesis (S) phase and Growth 2 (G2) phase.During the S phase, the chromosomes (i.e., the genetic material) of a cell are duplicated.Mitosis is a type of cell division that follows the interphase of the cell cycle by which a somatic (body) cell divides to produce two genetically identical daughter cells.In conclusion, Mitosis is a type of cell division that helps to maintain the chromosome number of the original cells by dividing cells that previously duplicate their genetic material (DNA) during the interphase (S phase).

hasn't erupted in 65,000 years)?
A. Mount McKinley
B. Death Valley
C. Yosemite National Park
D. Yellowstone National Park
Answer:
D.
Explanation:
Yellowstone National Park
Answer:
B
Explanation:
The amusement park will be located in a hot climate. The engineers want to select a material for the giant slide that will prevent the surface from getting too hot. Based on the specific heat values, what material would be the best choice? A.Plastic, because it takes more energy to raise its temperature B.Iron, because it takes more energy to raise its temperature C.Plastic, because it takes less energy to raise its temperature D.Iron, because it less energy to raise its temperature
Answer:
A
Explanation:
The correct answer would be plastic because it takes more energy to raise its temperature.
The specific heat capacity of a substance is the amount of heat required to raise the temperature of the substance by one degree. The more the specific heat capacity of a substance, the more the heat required to raise its temperature.
The specific heat capacity of plastics is generally more than that of metals. Hence, metals will get heated faster than plastics under the same condition. More energy would be needed to raise the temperature of plastics when compared to metals.
the correct option is A.

Why are invasive species dangerous to the environment?
A)They pollute the environment.
B)They are always predators.
C)They threaten biodiversity.
D)They bring abiotic factors.
Answer:
C
Explanation:
They threaten the other animals. They can take their food, homes, and they don't have natural predators.
Invasive species are dangerous to the environment as they threaten the biodiversity. Thus, the correct option is C.
Invasive species are those imported species that are able to thrive rapidly in another foreign area by adapting and reproducing quickly.
Invasive species of plants and animals lead to an increase in the competition for survival, which results in decrease in the population of the native species.
The invasive species also affect the food web that is existing in the particular ecosystem, because of which other all organisms which are part of the food web are affected. They outcompete the native species for food,
Thus, biodiversity is threatened due to the invasive species.

A rich variety of genetic material in an ecosystem will:
1. reduce the biodiversity of the ecosystem
2. decrease the carrying capacity of the ecosystem
3. reduce the likelihood of future medical discoveries
4. increase the chances that some organisms will survive change
A rich variety of genetic material in an ecosystem will increase the chances that some organisms will survive change.
What is an ecosystem?An ecosystem contains all the organisms and the biological environment (which contain abiotic and biotic factors ) with which they show interaction.
These biotic and abiotic components are related concurrently through nutrient and water cycles and energy discharges.
Energy joins the procedure through photosynthesis and is interspersed into plant tissue.

Morphological distinction is one of the steps necessary for speciation to occur.
What are the other two?
Answer:
Genetic Separation / Geographic isolation
Explanation:
Morphological distinction (or phenotypic differentiation) can be defined as the diversification of a set of observable physical characteristics in a population, capable of differentiating certain species.
The genetic separation occurs when the division of a group of genes into two or more pools of genes separated over time and depending on several other situational factors.
Geographic isolation occurs due to the physical separation of subpopulations of a given species. The barriers that isolate these subpopulations can be, for example, a river that cuts through a plain, a valley that divides plateaus or a portion of the sea that separates islands and continents.

Neurons are cells of the nervous system. As part of its normal function, a
neuron pumps sodium ions (Na + ) out of the cell and potassium ions (K + ) into the cell. Which statement describes the role of energy in this process?
a. The process releases energy that is used to make ATP.
b. The process releases energy in the form of heat.
c. The process requires energy that is provided by the sodium and potassium ions.
d. The process requires energy that is provided by ATP.
Thank you! :)
Answer:
D. The process requires energy that is provided by ATP.
Explanation:
Neurons use a pump called the sodium-potassium pump, which normally pumps sodium ions out of the cell and pumps potassium ions into the cell.
This pump goes against the concentration gradient to create the resting membrane potential.
Since the pump goes against the concentration gradient, it requires energy, because it is not passive diffusion.
So, D is the correct answer, as the process requires ATP energy.
Neurons are cells of the nervous system. As part of its normal function, a
neuron pumps sodium ions (Na + ) out of the cell and potassium ions (K + ) into the cell. The process requires energy that is provided by ATP. The correct answer is option D.
What is the role of sodium potassium pump ?The role of the sodium potassium pump is the muscle contraction and the nerve impulse. In exchange of 2 potassium ions is the displacement of 3 sodium ion and this exchange is against the concentration gradient thus requires the molecule of ATP for the transfer of the ions.
The Na+/K+-pump an active transporter uses ATP hydrolysis in energy source to move ions across the neuronal membrane down their concentration gradients and assigned specific functions associated with the generation of the action potential as well as with the maintenance of other active transport.

Why are subduction zones not commonly found at convergent continental-continental boundaries?
Answer:
the subduction zone is commonly found in convergent continental-continental boundaries since it is where two continental crusts meet, and the force forces one crust to subduct under another one.
Explanation:
When do mountains get built?
Answer:
Movements of tectonic plates create volcanoes along the plate boundaries, which erupt and form mountains. A volcanic arc system is a series of volcanoes that form near a subduction zone where the crust of a sinking oceanic plate melts and drags water down with the subducting crust.
