Consider the cell cycle; which stage takes pretty much the same amount of time regardless of cell type? Explain
Natalija [7]

Answer:

The correct answer would be mitosis or M phase.

Mitosis or M phase is the phase of the cell cycle during which the actual division of the cell takes place that is, the division of nuclear content. It is also termed as karyokinesis.

It is primarily divided into four stages:

  • Prophase
  • Metaphase
  • Anaphase
  • Telophase.

It results in the equal distribution of  chromosomes into two daughter cells.

It is followed by cytokinesis by which cytoplasmic content is equally divided into the two daughter cells.

What percent of iodine has decayed if 5 half lives have passed?
goldfiish [28.3K]

Hello!

A half-life is the amount of time it takes half of an element to decay. For example, after one of carbon's half-life, half of carbon would've decayed.

Now, we can calculate how much has decayed if 5 half lives have passed.

1 -> 50% (1) -> 25% (2) -> 12.5% (3) -> 6.25% (4) -> 3.125% (5)

Therefore, there would be 3.125% left of iodine. However, your question is asking what percent has decayed. Therefore, subtract 3.125 from 100% to get your final answer.

100 - 3.125 = 96.875

Therefore, your final answer is 96.875% of iodine has decayed if 5 half lives have passed.

Hope this helps!

During respiration, a seed metabolizes sugars. what is the source of the sugar metabolized by the seed?
pashok25 [27]

The source of the sugar metabolized by the seed is photosynthesis.  

The procedure used by plants to transform light energy into a chemical form of energy is known as photosynthesis. The chemical energy can afterward be discharged to fuel the plants to perform their activities.  

During photosynthesis, carbon dioxide and water can be combined in the existence of chlorophyll and sunlight to generate oxygen and glucose (carbohydrates). However, the prime component generated in the procedure is glucose (sugar) that is the molecule, which generates energy to mediate the activities of the cell.
