Brut [27]

<u>Some ways to increase carbon dioxide and To reduce carbon dioxide:</u>

WAYS TO INCREASE CARBON DIOXIDE

Consuming electricity: The main reason for the $CO_2$ emission is the burning of fossil fuels. 41% of the $CO_2$ emitted in the US form generating electricity.

Deforestation: cutting of trees increases the $CO_2$ in the atmosphere.

WAYS TO REDUCE CARBON DIOXIDE:

Reuse and recycling: By buying used products and reselling or recycling are reduce your carbon emissions.

Planting more trees: trees are used to stored the removed $CO_2$ from atmosphere $CO_2$ helps the plants for photosynthesis. so plant more trees.

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.
