Animals can be engineered to require less food, grow quicker, and leave behind less evironmentally damaging waste.
-Animals can be engineered to be more resistant to harmful and painful diseases.
-Animals can be engineered to produce more omega-3 fatty acids, to provide leaner meat, and to make more milk.
-Animals can be engineered so their tissues, organs, and cells can be transplanted into humans.
-Animals can be engineered to produce certain substances that offer a new source of medicine.
-Animals can be engineered to reproduce much faster.

negative impacts.

It is unethical.
-Some food companies have refused to use meat or milk that is from genetically engineered animals.
-Some consumers are complaining that the animal drug rules do not regulate genetically modified animals properly.
-This process is potentially dangerous and can be very harmful.

Prophase of meiosis I has some important differences from prophase of mitosis. These differences include: ___________BLANK pair,
Viefleur [7K]

Complete question:

Prophase of meiosis I has some important differences from prophase of mitosis. These differences include: ___________BLANK pair, and _________BLANK occurs.

A: chromatids; condensation

B.,chromosomes; separation

C. homologous chromosomes; crossing over

D. homologous chromatids; separation

Answer:

C. homologous chromosomes; crossing over

Explanation:

Prophase I of meiosis and prophase of mitosis are quite distinct with respect to the events occurring in the cells. Prophase-I of meiosis is a relatively long stage. The Zygotene stage of prophase-I includes the pairing of homologous chromosomes. This pairing is mediated by synaptonemal complex and the process is called synapsis. The paired chromosomes undergo the process of crossing over during the pachytene stage of prophase-I. In crossing over, the non-sister chromatids of the bivalents exchange some genetic material between them. The events of synapsis and crossing over do not occur during prophase of mitosis.
