If the sample of matter is a pure substance, meaning made up of only one type of atom.
Answer: pollen
Explanation: The anthers bear the pollen grains which contains the male gamete(sperm).
Answer:
Q1: C. salinity Q2: density Q3: B. densest, least dense Q4: C. closest to the surface
Explanation:
Q1: The term "salinity" refers to the concentrations of salts in water or soils. Q2: when the amount of salt in the water increase which usually gathers mostly at the shallow top of the ocean which is where the warm shallow water gathers, when the warm water has enough salt in it, it sinks to a deeper location causing its density to heighten and that's also what makes it cold. Q3: When layers form in the ocean, the water containing the most dissolved salt tends to form the bottom layer. The water having the least amount of salt is usually on top, because it is the least dense. As more solids are dissolved in water, the water becomes more dense. Q4: Cold water has a higher density than warm water. Water gets colder with depth because cold, salty ocean water sinks to the bottom of the ocean basins below the less dense warmer water near the surface. I really need brainliest please do so.
Answer:
they need it to function properly
Answer:
Soil erosion.
Explanation:
Soil erosion is the impact of floods on ecosystems because the floods moves very fast which takes soil with itself. Due to soil erosion, the productive layer of the soil or the layer in which nutrients are present are eroded which has a negative impact on the plants due to unavailability of nutrients. The floods moves very fast and the soil has no the ability to hold its particle tightly which leads to erosion of the soil that negatively affected the ecosystem.
