At an intercalated disc, at an intercalated disc, the cell membranes of two cardiac muscle fibers are completely separated by a synapse. two cardiac muscle cells are connected by gap junctions. t-tubules unite the membranes of the adjoining cells. the myofibrils are loosely attached to the membrane of the disc. all of the answers are correct.

6. in domesticated cats, the following are independently assorting: normal ears (t) is dominant to tufted ears (t); curved whiskers (c) is dominant to straight whiskers (c); the presence of six toes (s) is dominant to five toes (s); gene for hair length is an x-linked codominant. the three phenotypes for hair length are long (xhxh), medium (xhxh), and short (xhxh); medium is the heterozygous condition. given two parents: ttccssxhxh x ttccssxhy how many different gametes could be formed in the female cat with respect to these four traits? how many phenotypes are possible in the offspring from this mating?

Crossing over and independent assortment are important activities that occur during meiosis. what is the significance of these activities

How are fungi more like an animal? they have a cell wall. they are heterotrophs that absorb their food. they produce seeds and have membrane-bound nucleus. they use sunlight for photosynthesis.
