Answer:
facilitated diffusion doesn't require energy, while active transport requires energy. Facilitaded difusion happens down the concentration gradient (molecules move from area of higher concentration to area of lower concentration), while active transports happens up the concentration gradient (from lower concentration to higher concentration).
Explanation:
Answer:
3, 1, 4, 2
Explanation:
The effects described are called phototropism, where light affects the direction of growth of the plant.
Auxin is a plant growth hormone that promotes growth of the plant by encouraging cell proliferation.
Light degrades auxin, so it is found more in the shaded side of the plant. This causes the cells in this region to proliferate more, and therefore there is more growth on the shaded side of the plant.
This causes the plant to bend towards the light.
Clastic sedimentary rocks
Most rocks that form from fragmental rock particles are classified as clastic sedimentary rocks.
Clastic sedimentary rocks are rocks that are formed by weathering processes due to exposure of pre-existing rocks to wind, ice, and water which breaks down the pre-exsiting rocks into chunks, pebble, sand, and smaller rock particles. Types of clastic sedimentary rocks include; conglomerate, breccia, shale and sandstone.
The correct statements are I, III and IV.
An angiosperm refers to a plant, which exhibits flowers and generates seeds enveloped within a carpel. The angiosperms include a large group of herbaceous plants, grasses, shrubs, and the majority of trees. While gymnosperms refer to the plants that exhibit seeds but not safeguarded by any kind of fruit or ovary. It includes the cycads, gingko, and conifers.
Both the angiosperm (sunflower) and gymnosperm (gingko) are seed-bearing plants. However, the seeds of a sunflower are safeguarded by a flower or fruit, while for the gingko, there is no mechanism like that, i.e, there is not any kind of protection. Additionally, sunflower exhibit phenomenon of double fertilization, which is not witnessed in the case of gingko.
