Answer: a. Haploid spores are released to form zygotes, which grow into gametophytes.
A fern has two different stages of the life cycle; the sporophyte and gametophyte. In the sporophyte, spores are released. After this life cycle comes the gametophyte or the sexual phase, <span>haploid spores are released to form zygotes, which grow into gametophytes. </span>
The 2 major components or parts that compose or make up the plasma membrane of a eukaryotic cell would be the phospholipids arranged as a bilayer, having phospholipids arranged side by side in an upright and inverted manner, allowing for the hydrophobic and hydrophilic regions to interact respectively, and also Protein molecules, more specifically Transmembrane Proteins and Integral Proteins.
Answer:
Intrusive rocks are coarse-grained in texture and crystallise slowly from magma deep in the earth's crust. Extrusive rocks are fine-grained in texture and crystallise quickly from lava on or near the earth's surface. The mineralogy determines the type of rock.
Answer:
Although it causes drag, it also causes intense heat. Specifically, shuttles face intense temperatures of about 3000 degrees Fahrenheit (about 1649 degrees Celsius) [source: Hammond]. Blunt-body design helps alleviate the heat problem.
