Most earthworms have the gizzard in the anteriormost segments, and many have no gizzard at all. The primary function of the esophageal region in most earthworms (including the lumbricids) is calcium carbonate secretion. The usual patterns are below. Mouth>pharynx>gizzard>esophagus>intestine Mouth>pharynx>esophagus>crop>gizzard>intestine
The source of protein comes from caterpillars, crickets, red ants, and June beetles. Out of those, the caterpillar has the highest amount of protein. The source of lipids comes from the cricket, red ant, and June beetle. The cricket has the highest amount of fat. Overall the best source that TraFly eats is caterpillars, because it has the highest amount of protein and the lowest amount of lipids and carbohydrates.
D) All of the F1 progeny resembled one of the parental (P) plants, but only some of the F2 progeny did.

A) A monohybrid cross involves a single parent, whereas a dihybrid cross involves two parents. B) A monohybrid cross produces a single progeny, whereas a dihybrid cross produces two progeny. C) A monohybrid cross involves organisms
The molecular basis of the smooth (alleles: SS or Ss) and wrinkled (alleles: ss) pea seeds involves the gene that codes for the enzyme phosphorylase. Peas that inherited the genotype “ss” (wrinkled peas) have an inactive form of the enzyme. Peas that are Ss have smaller amounts of the enzyme than SS seeds (not necessarily true because it is

Which have the two lowest?
There are about 9000 species of annelid known today. The ascaris are an intestinal worm, resembling earthworms in size and appearance. MATERIALS: * Dissecting pins * Gloves * Forceps * Lab apron * Scissors * Paper towel * Scalpel * Water * Dissecting probe * Preserved earthworm * Hand lens * Dissection tray PROCEDURE: We first put on our lab aprons, gloves, and (for the girls) make sure your hair is pulled back. We get the dissection tray and place the earthworm. Grab two dissecting pins and place them one on each end of the earthworm.

Lastly, if you haven’t noticed, the long cylindrical and no legged animals are part of the enormous worm family! Planarians are worms, and so are earthworms. Given these points, planarians and earthworms are somewhat alike in three ways. They both have similar body systems, are decomposers, and part of the same family. Planarians and earthworms are different species, therefore, they have many differences.
Introduction: Using garlic to kill bacteria both externally and internally is a natural answer to the problem of ingesting the drugs and toxins contained in other products. Body Paragraph 1: Bacteria Bacteria are very tiny microscopic organisms that are unicellular which means they are made up of a single cell. They are the smallest and simplest organisms on earth. Bacteria also come in a variety of shapes and sizes, and their size is measured in micrometer which is a millionth of a meter. Bacteria are found everywhere in the world in all types of environment.
We zoomed in and we decided it was a bacilli bacteria because the dots looked almost like ovals. The third slide we put on with a low zoom and it looked like a bunch of dots again. We zoomed in and we could clearly tell it was cocci bacteria because they dots were almost perfect circles. We noticed that the onion, elodea, and the human cells all look different. The elodea cells are very small and round.
