Through expanding, some galaxies are on a collision course with us.
Answer - <span>C) Trees and shrubs provide shade, which keeps the water temperature cooler. Lower temperatures allow the water to hold more oxygen, which in turn creates a healthier habitat for the trout.</span>
Reasoning - The back story is if the water temperature is being changed. It will affect the trout indirectly warming the water. In turn if you have shades and shrubs to provide it for cooler areas it will preserve O2 a Certain Habitat for the Species.
Answer: etiolation of plant growth in shade, with fast growing cell without chloroplasts. Out of shade, cell differentiate again to produce photosynthesising cells
Explanation: It is a subjective decision as to what is ‘best’. Good examples are plant responses to changes in the nutrient supply.
when soil nitrogen is depleted some plants, such as legumes, grow nodules on their roots, with cells that release chemical signals to attract nitogen fixing bacteria.
Lack of light induces etiolation in many plants. New cells elongate and develop without chloroplasts, with rapid cell division exhibiting gravitropism, extending upward. When they grow beyond the shade area, cell differentiation changes again, to produce photosynthesising cells.
Answer:
Substitution Mutations
Explanation: A substitution mutation occurs when specific bases (A, T, C or G) in a gene are swapped for different ones. This type of mutation doesn't cause a difference in the number of bases like insertion or deletion mutations do. Substitution mutations just switch out one or more bases for different ones.
Hope this helps :3
