Answer: Option D: Neuromuscular junction
Explanation:
This is the site of transmission of chemical signal also known as a chemical synapse between a neuron and a muscle fibre. Most of the time the chemical released which is a neurotransmitter is acetylcholine. When released, it stimulates the release of calcuim ions present in the sarcoplasm: an endoplasm like structure in the muscle fiber that contains calcium ions.
Because high iron baby formula will raise her iron levels and help anemia.
Answer:
Explanation:
The flatworms are acoelomate organisms that include many free-living and parasitic forms. Most of the flatworms are classified in the superphylum Lophotrochozoa, which also includes the mollusks and annelids. The Platyhelminthes consist of two lineages: the Catenulida and the Rhabditophora. The Catenulida, or “chain worms” is a small clade of just over 100 species. These worms typically reproduce asexually by budding. However, the offspring do not fully detach from the parents and therefore resemble a chain in appearance. All of the remaining flatworms discussed here are part of the Rhabditophora. Many flatworms are parasitic, including important parasites of humans. Flatworms have three embryonic tissue layers that give rise to surfaces that cover tissues (from ectoderm), internal tissues (from mesoderm), and line the digestive system (from endoderm). The epidermal tissue is a single layer cells or a layer of fused cells (syncytium) that covers a layer of circular muscle above a layer of longitudinal muscle. The mesodermal tissues include mesenchymal cells that contain collagen and support secretory cells that secrete mucus and other materials at the surface. The flatworms are acoelomates, so their bodies are solid between the outer surface and the cavity of the digestive system.
Fermantion and cellular respiration in that they both begin with series of reaction known as glycosis, which break glucose molecules into smaller pyruvate molecules
P + q = 1 <span>correctly represents the possible frequencies of each genotype.
</span>The sum of the allele frequencies at the locus must be equals to 1<span>,
so </span>p<span> + </span>q<span> = </span><span>1</span>
