The model below represents a phase of meiosis. what stage of meiosis does the picture below represent? 1points a drawing of a phase of meiosis with the chromosomes paired up and the centrioles formed. a prophase i b prophase ii c anaphase i d anaphase ii

The correct answer will be option A (prophase I).

Explanation:

Meiosis is a type of cell division in which a single cell divides to form 4 daughter cells with half number of chromosomes of parents.

Meiosis proceeds in two-step division processes that is meiosis I and meosis II. Each stage of cell division occurs in four phases- prophase, metaphase, anaphase and telophase.

During prophase I, the chromosomes begin to condense and form X-shaped structures, chromosomes pair up ,shows recombination or crossing over, shows meiotic spindles between the centrioles at oppsoite poles and nuclear membrane which starts degrading at the end of prophase phase.

Thus, option A (prophase I) is the correct answer.

significant amounts of nitrogen oxides, carbon monoxide, and other pollution

explanation:

passenger vehicles are a major pollution contributor, producing significant amounts of nitrogen oxides, carbon monoxide, and other pollution. in 2013, transportation contributed more than half of the carbon monoxide and nitrogen oxides, and almost a quarter of the hydrocarbons emitted into our air.

step 1: replication fork formation.

step 2: primer binding.

step 3: elongation.

step 4: termination.

explanation:

hope this !
