The clade Ecdysozoa includes <u>8</u> phyla, of which you will be observing only two in this week's lab.
<h3>What is Ecdysozoa?</h3>
- Arthropoda (insects, chelicerata, crustaceans, and myriapods), Nematoda, and a few other minor phyla are all included in the group of protostome creatures known as Ecdysozoa (/kdsozo/).
- Aguinaldo etal. provided the initial definition of them in 1997, largely based on phylogenetic trees generated with the use of 18S ribosomal RNA genes.
- The Ecdysozoa were firmly supported as a clade in a sizable study conducted in 2008 by Dunn etal.
- A clade is a group made up of all the descendants of a common ancestor.
- All animals that grow by ecdysis, or moulting their cuticle, are included in this group, which is also supported by morphological characteristics.
<h3>What is phyla?</h3>
- A phylum is a taxonomic rank or degree of classification in biology that comes before a kingdom and after a class (/falm/; plural: phyla).
- Phylum and division are similar terms according to the International Code of Nomenclature for algae, fungus, and plants, but division has historically been used in botany instead of phylum.
- Depending on definitions, there are between 31 and 14 phyla in the plant kingdom Plantae, 8 phyla in the fungus kingdom Fungi, and roughly 31 phyla in the animal kingdom Animalia.
- The links between phyla, which are housed in more expansive clades like Ecdysozoa and Embryophyta, are currently being revealed via phylogenetic studies.

They may have ran out of oxygen, or they may not have been water dwelling snails, as not all are, lack of food, no flow of water into and out of the tank would cause them to run out of oxygen.
<h2>Mitotic Cell Cycle</h2>
Explanation:
a. Cytochalasin: an inhibitor of actin microfilament
- Cytokinesis is the process by which cytoplasm is divided into two cells hence generation of two daughter cells
- In animal cells the division of cytoplasm starts with the assembly of contractile ring
- Contractile band consists of actin and myosin and catalyze cleavage furrow formation
- Cytochalasin is a drug that blocks the polymerization of actin filament
- When cytochalasin is added dividing cell fails to undergo in cytokinesis due to defective assembly of contractile band
b. Colchicine: an inhibitor of microtubule formation
- Colchicine tightly binds with free tubulin dimer and prevents its polymerization
- In this case mitotic spindle apparatus do not assemble and cells unable to do partitioning of chromosomes into two groups
- Thus cell division is arrested
c. Aphidicolin: an inhibitor of DNA Polymerase activity
- Aphidicolin is used to induce cell cycle arrest via specific inhibition of DNA Polymerase α
- It blocks the cell cycle at early synthesis(S) phase
d. Emetine: an inhibitor of ribosome activity
- It blocks the protein synthesis in eukaryotic cells by binding to small subunit(40 S) of ribosomes
- It interferes with the synthesis and activities of DNA and RNA
Answer:
Explanation:
Reproduction may be asexual when one individual produces genetically identical offspring, or sexual when the genetic material from two individuals is combined to produce genetically diverse offspring. Asexual reproduction occurs through fission, budding, and fragmentation.
