The two groups differ in the composition of the cell wall and the lipids in the cell membrane. 3. ... Organelles contribute to efficiency in eukaryotic cells because they concentrate the biochemicals needed for chemical reactions so that the reactions proceed more rapidly.
Answer:
1. Step 1: DNA Replication. Just before the cell divides, its DNA is copied in a process called DNA replication. ...
Step 2: Chromosome Segregation. The two chromosomes segregate, or separate, and move to opposite ends (known as "poles") of the cell. ...
Step 3: Separation.
2. Mitosis consists of four basic phases: prophase, metaphase, anaphase, and telophase. These phases occur in strict sequential order, and cytokinesis - the process of dividing the cell contents to make two new cells - starts in anaphase or telophase. Stages of mitosis: prophase, metaphase, anaphase, telophase.
Answer:
glucose is the food for producers. they make their own food with the photonic energy from the sun. this energy is then passed to primart consumer, then secondary consumers, then tertiary consumers. energy decreases as it climbs the food pyramid. only 10 percent of the previous tier is carried onto the next tier.
for example if plants had 10,000 kilocalories, grasshoppers would get 1,000 kilocalories,
frogs would get 100 kilocalories,
and snakes would get 10 kilocalories.
kilocalories are a unit of energy.
i hope this helped! have a nice day
