A. in ordered tetrad analysis, what is the maximum rf that you could observe between a gene and its centromere? (hint: what rf would you observe between a gene and the centromere of the chromosome on which it resides if the gene were distant enough from the centromere so that there was at least one crossover, and often more than one crossover, between them in every meiosis? ) b. can a gene and its centromere be unlinked? explain. c. suppose in an ordered tetrad analysis you observe an rf of 30% between a gene and its centromere. given your answer to part (a), do think that 30 m. u. is an accurate estimate of the distance between the gene and the centromere?

the answer is d.) homologous; have mammary glands

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.

the correct answer is - d. china has a large and growing population.

the fact that china has a large (the biggest) population, and it is still growing, doesn't hinder the agriculture production in the country. in fact, it can for increased production in the agriculture, since there's more labor force, as well the sheer mass of people produces lots of scientists that come up with new inventions as to how to improve this sector. nice example is the inner mongolia region in china, in general dominated by the gobi desert, but few scientist came up with a nice idea as to how to make the region productive by using plants that are very resistant to droughts, so lots of people have been employed, and the region is becoming greener and greener each year, and the production of food in this region is also increasing.
