Here are the 8 steps of meiosis:
<span>1. Each chromosome makes an identical copy of itself, forming two exact halves called chromatids. The chromosomes then thicken and shorten into a form that is visible under a microscope. The nuclear membrane disappears. </span>
<span>2. Each chromosome is now made up of two chromatids, the original and an exact copy. Similar chromosomes pair with one another, forming homologous chromosome pairs. The paired homologous chromosomes line up at the equator of the cell. </span>
<span>3. The chromosomes separate from their homologous partners and move to opposite ends of the cell. </span>
<span>4. The nuclear membrane reforms and the cell divides. The paired chromatids are still joined. </span>
<span>5. Each cell contains one member of each homologous chromosome pair. The chromosomes are not copied again between the two cell divisions. </span>
<span>6. The chromosomes line up at the equator of the cell. </span>
<span>7. The chromatids pull apart and move to opposite ends of the cell. The nuclear membrane forms around the separated chromosomes, and the cell divide. </span>
<span>8. THE RESULT: Four new cells have formed from the original single cell. Each new cell has half the number of chromosomes present in the original cell.</span>
Answer:
The complex eukaryotic cell ushered in a whole new era for life on Earth, because these cells evolved into multicellular organisms. Evidence supports the idea that eukaryotic cells are actually the descendents of separate prokaryotic cells that joined together in a symbiotic union.
Answer:
B. Something made up of one cell is considered living.
Explanation:
All living things are made up of at least one cell
I can be wrong, if wrong, sorry.
This depends on the stimulus. if it is a positive stimuli like smell of food, the animal will look for it, if its negative (being frightened) the animal will fight or run
Answer:
C.. the ability to exert a submaximal force repeatedly over time
Explanation:
Muscular endurance is defined as the number of times or rate at which a person can perform an exercise. It is measured with the number of repetitions carried out. Submaximal force has to do with the force exerted during exercises.
