The cladogram of the kingdom animalia shows the relationship of selected animals based on their shared anatomical features. the
black numbered squares represent features that are critical for forming each branch in the animal kingdom. square one represents a dorsal nerve cord, which means the animals in all the branches have a dorsal nerve cord. which numbered square would represent the trait "mammary glands?" a.3
b.4
c.5
d.6
In the cladogram of the kingdom as illustrated, number 5 would represent the trait mammary glands. This trait distinguishes the class mammalia. Kangaroos, monkeys, and humans are all in this class. Kangaroos are in the order marsupialia, a different order than monkeys and humans. Monkeys and humans are placental animals and do not carry their young in pouches.
In meiosis I, homologous chromosomes separate, while in meiosis II, sister chromatids separate. Meiosis II produces 4 haploid daughter cells, whereas meiosis I produces 2 diploid daughter cells. Genetic recombination (crossing over) only occurs in meiosis I. D
Acetylcholine is an excitatory neurotransmitter secreted by motor neurons innervating skeletal muscle.
However, norepinephrine, gamma aminobutyric acid, and cholinesterase are not excitatory neurotransmitter secreted by motor neurons innervating skeletal muscle.
