Answer:
The enzyme you will be studying in this experiment is lactase, and the reaction it catalyzes is the hydrolysis of the disaccharide lactose into the monosaccharides galactose and glucose.
Explanation:
Answer: a. endoderm-bone
Explanation: In the context of embryonic development, bone tissue may arise from several precursor cell populations, such as the neural crest (some facial bones), lateral mesoderm (bones of the limbs, among others), and paraxial mesoderm (vertebrae and part of the skull). There is no evidence to suggest that any of the bony structures is derived from the endoderm germ layer.
Answer:
eagle- chordata phylum
ladybud- Insecta class
scorpian- Arachnida class
lobster- Crustacea class
snail- Mollusca phylum
Explanation:
The organism that contains a notochord at some of its life cycle stage are called chordates and all vertebrates are chordates so eagle comes under phylum Chordata.
Insecta is the largest class of phylum Arthropoda which contains organisms which have jointed legs, exoskeleton and segmented body for example ladybird, playing mantis, etc.
Arachnids are animals which have jointed legs and in this class spider are the largest order which contains scorpions, mites, ticks, etc.
Crustaceans are invertebrates which have hard shell made up of calcium for example lobster, prawn, shrimp, etc.
Mollusks are very large invertebrate phylum which contains a soft segmented body that is usually present inside a shell made up of calcium. for example snails.
Scientists collect information that allows them to make evolutionary connections between organisms. Similar to detective work, scientists must use evidence to uncover the facts. In the case of phylogeny, evolutionary investigations focus on two types of evidence: morphologic (form and function) and genetic.
