The answer is Arachnids.
Crustaceans, Insects, and Arachnids belong to the phylum Arthropoda.
Of mentioned characteristics, most of the Insects have both wings and antennae. Remember all butterfly, bees, beetles, etc. Crustaceans (crabs, lobsters, shrimp, etc) have antennae, but they have no wings.
Thus, the only group of the mentioned that shows <span>neither wings nor antennae is Arachnids. Arachnids include scorpions, spiders, ticks, etc. and as it is known, these groups have neither </span><span>wings nor antennae.</span>
The overexpression results in increased micro vessel density and lesion size in mice with induced endometriosis.
Endometriosis is a benign gynecological disorder.
- it's far characterized through the ectopic presence of endometrial glands and stroma out of doors of the uterine hollow space and is carefully related to dysmenorrhea, pelvic pain, and subfertility.
- In endometriosis, the involvement of vascular endothelial mobile growth issue (VEGF) and different angiogenic mediators has long been recognized endometriotic angiogenesis entails numerous pathways and the blockade of simply one single pathway won't effectively suppress Endometriosis
- Slit is a secretory glycoprotein which include 3 members, Slit1, Slit2, and Slit3, and become at first found to be secreted repellents in axon steerage and neuronal migration It has been shown to be an endogenously available inhibitor of leukocyte chemotaxis.
- receptor for Slit is the protein Roundabout (ROBO), which currently includes 4 members (ROBO1-4)

Mitochondria is the powerhouse of the cell
Hope this helped
<h3><u>Answer;</u></h3>
In metaphase I, the chromosome tetrads align on metaphase plate
while in metaphase II, chromosomes align on metaphase plate as they are in mitosis with only sister chromatids.
<h3><u>Explanation;</u></h3>
- Meiosis is a form of cell division that halves number of chromosomes when forming specialized reproductive cells such as gametes
.
- Meiosis occurs in two phases, namely; meiosis I and meiosis II. During homologous pairs of chromosomes align on the equatorial plane at the center of the cell.
- During metaphase II, the spindle fibers connect to the kinetochore of each sister chromatid. The chromosomes align at the equatorial plane, which is rotated 90° compared to the equatorial plane in meiosis I.
The rapid depolarization phase of the action potentials of myocardial contractile cells is due to Na⁺ ion.
The depolarization is caused when Na⁺ ions rapidly enters into neuron through open sodium channels. Sodium ions plays important role in various physiological process such as regulating blood volume, ph regulation, maintaining blood pressure, energy metabolism,osmotic equilibrium, excitation-contraction coupling, maintenance of cellular homeostasis, development and growth.
