The sodium potassium pump, works against its concentration gradient. it pumps ___________ ions out of the cell and _________ ions into the cell
The sodium-potassium pump works against its concentration gradient. it pumps potassium ions out of the cell and sodium ions into the cell.
A sodium-potassium pump system moves sodium and potassium ions against a large concentration gradient. It transports two potassium ions into cells with high potassium levels and pumps three sodium ions out of the cell into the extracellular fluid. Sodium-potassium pumps are found in many cell (plasma) membranes. The ATP-powered pump moves sodium and potassium ions in opposite directions against their respective concentration gradients. In one cycle of the pump, 3 sodium ions are pushed out of the cell and 2 potassium ions are taken up by the cell.

how does human activity cause disruptions in the ecosystem?
Answer:
Human impact on the environment or anthropogenic impact on the environment includes changes to biophysical environments and to ecosystems, biodiversity, and natural resources caused directly or indirectly by humans, including global warming, environmental degradation (such as ocean acidification), mass extinction and etc...
Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water.
A group of herbivores are separated from their individual population. In the new environment, the only edible
vegetation grows underground.
-What would be a like likely structural adaptation that would occur?
-Explain how step by step how this would result in the population changing over time?
Over time, an adaptation that will make it easier for herbivores to acquire food is a long neck.
What are herbivores?An herbivore is an organism that mostly eats plants. A herbivore can be any size, from tiny insects like ants to huge, massive elephants. Herbivores make up a substantial portion of the food web, which is a description of the species that eat other animals in the wild.
Humans are they herbivores?We are physically herbivorous, despite the fact that many people prefer to consume both plants as meat, giving us the questionable moniker of "omnivores." The good news is that it's still possible to dine like our ancestors: Vegetables, fruits, nuts, and legumes form the foundation of a wholesome vegan diet.

What happens to the 3 carbon sugar that exits the Calvin cycle?
By carbon fixation, 3-PGA molecules are transformed into glucose molecules, which are simple sugar molecules.
It corresponds to the second phase of Calvin's cycle. By carbon fixation, 3-PGA molecules are transformed into glucose molecules, which are simple sugar molecules. Energy for this stage is provided by ATP and NADPH generated during the light-dependent activities of photosynthesis. Thus, the Calvin cycle is a mechanism through which plants convert solar energy into compounds like sugars that may be stored for a long period. ATP and NADPH provide the sugars with their energy.
This procedure is referred to as reduction because 3-PGA molecules get electron transfers to produce glyceraldehyde-3 phosphate.

What is a Lytic infection and What is a lysogenic infection?
Answer:
Infection of a bacterium by a bacteriophage with subsequent production of more phage particles and lysis, or dissolution, of the cell. The viruses responsible are commonly called virulent phages. Lytic infection is one of the two major bacteriophage–bacterium relationships.
Lysogeny, or the lysogenic cycle, is one of two cycles of viral reproduction. Lysogeny is characterized by integration of the bacteriophage nucleic acid into the host bacterium's genome or formation of a circular replicon in the bacterial cytoplasm.

If a mutation causes you to get a new trait, by how natural selection works, that trait will disappear even if it will help you survive T or F
Answer:
False, natural selection would not cause the mutation to die out unless it harms reproductivity
Explanation:
Natural Selection works through many different aspects, here we see that a creature has developed a mutation. If the creature would be aided with this new found mutation it would not simply disappear. The creature would end up reproducing with similar creatures spreading this new mutation, and this is what natural selection is. Natural selection is when creatures with negitive mutations are unable to reproduce causing their gentic line to die out, while creatures with superior genetics continuously reproduce.
