- Which is false about animal xygote? it's produof fertilized egg it's totipotent stem cell rise in ecto meso and endoderm only debelop inside mother all above are trueUnlike life cycles found in many land plants and protist's life, animals do not go through alternations of generations. However, many animal life cycles include metamorphosis. Their development is said to be indirect. direct. viviparous. oviparous.Tetra pods evolved from ___ . a. sharks b. teleosts c. lobe-finned fishes d. placoderms
- Which word-part is not defined correctly? A. echino = radial B. pod = foot C. arthro = jointed D. phore = having/bearing E. cephalo = head 12In 1798, a stuffed platypus specimen was delivered tothe British Museum. Reports that it laid eggs createdmuch confusion. To modern biologists, a platypus isclearly a mammal. It has fur and the females producemilk. Young animals have typical mammalian teeth thatare replaced by hardened pads of the “bill” as the animalmatures. Why do you think modern biologists can moreeasily accept that a mammal can have some reptileliketraits than scientists who were considering this animal inthe late 1700s?4. The Malpighian tubules of insects grind food into find particles before it goes to the hind-gut have ostia around the outer edge are functionally equivalent to the vertebrate kidney secrete juvenile hormone are found in the mesothorax 5. Lepidoptera caterpillars differ from sawfly caterpillars by having more prolegs by having parthenogenesis in many species by having a pair of stemmata rather than multiple stemmata on each side by being crochets on their feet in movement through looping for some family 6. Hemipterans are also known as book lice have piercing and sucking mouthparts are hexapods are endopterygotes include aphids, scale insects and earwigs
- Insects have three thoracic (trunk) segments. While researchershave found insect fossils with pairs of wings on all threesegments, modern insects have wings or related structureson only the second and third segment. It turns out thatin modern insects, Hox gene products act to inhibit wingformation on the first segment. The treehopper insect (above)is somewhat of an exception. In addition to having wingson its second segment, the treehopper’s first segment has anornate helmet that resembles a set of thorns, which a recentstudy has found to be a modified, fused pair of “wings.” Thethorn-like structure helps to camouflage the treehopper intree branches, thus reducing its risk of predation. Explain howchanges in gene regulation could have led to the evolution ofsuch a structure.Whereas most sarcopterygiians are oviparous (lay eggs), some sharks have viviparity (live birth) similar to that seen in mammals. This shared characteristic is an example of _______. a homologous trait an analogous trait divergent evolution a synapomorphy an ancestral traitWhich among these insects secrete seducin by the male which both attracts andpacifies the untamed female so that a connection is established?A. Bombus lapidaries.B. Periplaneta Americana.C. Eciton burchellii.D. Nauphota cinerae. How would you classify the type of ovariole of the following orders Neuroptera,Lepidoptera, some Coleoptera, Diptera andHymenoptera?A. polytrophic type of ovarioleB. telotrophic type of ovarioleC. panoistic type of ovarioleD. both B and C Which part of the egg is closely associated to the chorion?A. yolk deutoplasmB. vitelline membraneC. nuclear cytoplasmD. periplasm What is the major control centers of oogenesis that secretes ecdysone?A. headB. fat bodiesC. ovariesD. corpora allata

Three major lineages of mammals had emerged by the early Cretaceous period. In a tabulated form, compare these three lineages to illustrate their diversity in terms of: a. Embryonic development b.
