perennial grass is 2-4 tall. Cultivation: The preference is full sun, mesic to dry conditions, and very sandy soil. Propagation occurs primarily by dividing clumps of plants and their rhizomes, as most seeds are not viable.Range & Habitat:<span> The native Beach Grass is rare in Illinois and state-listed as endangered.</span>
Answer:
C. if the homologous chromosome lacks the deletion.
Explanation:
Homologous chromosomes are the pair of chromosomes that are similar in their basic morphology and genetic constitutions. In a diploid organism like humans, two alleles of a particular gene are present on the corresponding loci on the homologous chromosome. Therefore, the deletion of a genetic segment from a chromosome will not be fatal if its homologous chromosome carries that genetic segment and has no deletion in that particular region.
For instance, the deletion of a genetic segment from a chromosome carrying the gene for eye color would be tolerated and would remain in the population if its homologous chromosome lacks deletion in this region and carries the allele for the eye color.
The
peripheral nervous system (PNS) consists of nerves that transmit impulses back
and forth between the central nervous system, the skeletal muscles, and the
skin.
<span>The
PNS consists of the nerves and ganglia that are located outside the brain and
spinal cord (CNS). The main function of the PNS is the connection between the
brain and spinal cord and the rest of the body.</span>

Answer:
female gametophytes
Explanation:
The cell called megasporocyte (2n) is usually the mother cell of the megaspores, which are the female spores of spermatophyte plants.
After an meiosis, the megaspore mother cell (2n) will give rise to 4 megaspores (n). Three of these megaspores usually degenerate. The functional megaspore will then develop into the megagametophyte, which will be called the embryonic sac. Initially the megaspore grows and its nucleus divides.
