Answer:

The steps in making packaging and exporting a protein from a cell are listed below in the following points:

Protein is made from the Ribosomes.

These proteins are gathered in the endoplasmic reticulum.

From ER the proteins are exported to the Golgi bodies. These Golgi apparatus is found in the vesicles.

The Golgi bodies modify the protein to suitable forms that can be absorbed.

Finally it is transported to all part of cells in our body.

Answer:

Forms of fossils and there arrangement with layer of rock.

Explanation:

The seashore is a significant place for the depositional work of waves and it's also one of the significant places for the erosion and weathering of rocks.

The presence of sedimentary rocks along the cliffs are essential for the discovery of fossils of plants and animals. Fossils of shells and other creatures that were of marine origin are mostly discovered near excavation sites. Fossil helps to prove the age of rocks and strata.

When a living organism dies, it stops taking in new carbon. Thus, as the radioactive carbon-14 decays, the ratio of carbon-12 to

Alexxandr [17]

Answer: The fossil is 11459 years old.

Explanation:

Half-life of carbon-14 = 5700 years

First we have to calculate the rate constant, we use the formula :

$k=\frac{0.693}{5700\text{years}}$

$k=1.21\times 10^{-4}\text{years}^{-1}$

Now we have to calculate the age of the sample:

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 = $1.21\times 10^{-4}\text{years}^{-1}
t = age of sample = ?
a = let initial amount of the reactant = 100 g
x = amount decayed = 75 g
a - x = amount left after decay process = 100 - 75 = 25 g Now put all the given values in above equation, we get
[tex]t==\frac{2.303}{1.21\times 10^{-4}}\log\frac{100}{25}$

$t=11459years$

The fossil is 11459 years old.
