When seeds of early- and late-succession species were raised under low light conditions similar to those found in the understory of mature forest, researchers found that species with seeds had seedling survivorship in shade.

When seeds of early- and late-succession species were raised under low light conditions similar to those found in the understory of mature forest, researchers found that species with seeds had seedling survivorship in shade.

The correct answer for this is:

There was no relation between seed, size, and seeding survivorship.

Explanation:

Even though when in our case there was no direct relationship between speed, size, and seeding survivorship. It doesn't make it a generalization, because many factors intervene in this phenomenon. Now, light is a factor of growth, photosynthesis, and survival. However, this three-variable correlation was not found affected by the independent variable.

fertilization, pictured in figure 24.23a is the process in which gametes (an egg and sperm) fuse to form a zygote. the egg and sperm each contain one set of chromosomes. to ensure that the offspring has only one complete diploid set of chromosomes, only one sperm must fuse with one egg. in mammals, the egg is protected by a layer of extracellular matrix consisting mainly of glycoproteins called the zona pellucida. when a sperm binds to the zona pellucida, a series of biochemical events, called the acrosomal reactions, take place. in placental mammals, the acrosome contains digestive enzymes that initiate the degradation of the glycoprotein matrix protecting the egg and allowing the sperm plasma membrane to fuse with the egg plasma membrane, as illustrated in figure 24.23b. the fusion of these two membranes creates an opening through which the sperm nucleus is transferred into the ovum. the nuclear membranes of the egg and sperm break down and the two haploid genomes condense to form a diploid genome.

explanation:

the sphincter muscles at the end of the digestive tract is the anus.
