The right answer is 4).
The cytoskeleton is made up of biological polymers of proteins, sometimes called fibers because of their large size at the cellular level. They are classified into three categories:
Microfilaments: involves in cytoplasmic phenomena (division, endocytosis, migration).
Intermediate filaments: Maintenance of the nucleus structure.
Microtubules: Involved in the separation of chromosomes during mitosis.
Answer:
100% of offspring will be black and white
Explanation:
BW = Black and white
Because 4 out of 4 offispring fom the punnett squares have the genotype of BW, 100% of the offspring will be black and white
Answer:
Explanation:
Biologists have tracked down genes that control the handedness of snail shells, and they turn out to be similar to the genes used by humans to set up the left and right sides of the body.
The finding, reported online in advance of publication in Nature by University of California, Berkeley, researchers, indicates that the same genes have been responsible for establishing the left-right asymmetry of animals for 500-650 million years, originating in the last common ancestor of all animals with bilateral body organization, creatures that include everything from worms to humans.
"Previous studies indicated that the methods for breaking left-right symmetry in animals seem to differ widely, so there was nothing suggesting that the common ancestor of humans, snails and other bilateral organisms had a common strategy for left-right asymmetry," said Nipam H. Patel, UC Berkeley professor of integrative biology and of molecular and cell biology, and an investigator of the Howard Hughes Medical Institute.
