The light micrograph shows dividing cells near the tip of an onion root. Identify a cell in each of the following stages: propha
ad-work [718]

Mitotic division in onion root cells:

  1. Prophase: the emergence of chromatin threads that form chromosomes, the chromosomes are visible and overlap.
  2. Metaphase: chromosomes line up and line up in the middle of the equatorial plane. The centromere of the chromosome appears to have bonds with the kinetochores connected to the spindle threads.
  3. Anaphase: the centromere of the chromosome undergoes division then the chromosomes are pulled by the spindle threads towards the two opposite poles and leave the center of the equator that looks empty.
  4. Telophase: The cytoplasm divides into two identical-looking daughter cells. At the telophase stage, the process of cell division occurs in two parts and has identical properties.

Mitosis is a cell division through the stages of prophase, metaphase, anaphase, and telophase. The purpose of mitosis is for growth and regeneration which results in two daughter cells that are identical to the original parent cell. Mitosis occurs only once and lasts only during somatization.

Estimate the maximum time a person could listen to a sound of 87 decibels.
Kazeer [188]

The maximum time a person could listen to a sound of 87 decibels is: 8 hours

<h3>Meaning of Decibels</h3>

Decibels can be defined as the unit used by scientists to measure sound level.The values of Decibel ranges from a very low value to a very high value and the higher we get the more dangerous it is to our human ear.

In conclusion, The maximum time a person could listen to a sound of 87 decibels is 8 hours

Wood deposits recovered from an archaeological site contain 36% of the C-14 they originally contained. How long ago did the tree
Veseljchak [2.6K]

Answer: It was obtained 8515 years ago

Explanation:

Expression for rate law for first order kinetics is given by:

t=\frac{2.303}{k}\log\frac{a}{a-x}

where,

k = rate constant

t = age of sample

a = let initial amount of the reactant

a - x = amount left after decay process  

a) to find the rate constant:

Half life is the amount of time taken by a radioactive material to decay to half of its original value.

t_{\frac{1}{2}}=\frac{0.693}{k}

k=\frac{0.693}{5760}=0.00012years^{-1}

b) for completion of 36% of reaction

t=\frac{2.303}{k}\log\frac{100}{36}

t=\frac{2.303}{0.00012}\log\frac{100}{36}

t = 8515 years

The time was 8515 years.
