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.
Answer: Biodiversity
Explanation: Biodiversity is in all ecosystems and it's everywhere. The reason they can compete and both succeed is because of biodiversity, they are not stuck to eating one animal there are thousands of different types of animals and because of this their is enough to go around. However if their wasn't biodiversity and their food choice was limited one would fail if competing in the same ecosystem.

This question is incomplete
Explanation:
This question is incomplete. However, let's understand some terms
Activation energy is the minimum amount of energy required for a reaction to proceed. Under normal condition, when the activation energy is high, it takes longer for the reaction to proceed than when it is low.
The burning of marshmallow is an exothermic reaction as it involves the transfer of heat energy into the environment.
