I'm pretty sure they are. Most large objects, like a log, (We are talking tree log here right?) will be composed of cells of some sort or another. Hope that helps:)

Yes logs are made up of cells, Plant cells to be exact.

Andreas93 [3]

Answer:

Chlorophyll a- violet blue

Chlorophyll b - orange red

Carotenoids- green yellow

Explanation:

The three major plant pigments are chlorophyll a, chlorophyll b and carotenoids.

Various pigments are identified by their specific pattern of wavelength absorption in the spectrum of visible light. Chlorophyll a absorbs light in the violet-blue region, while chlorophyll b absorbs orange-red light. Chlorophyll a and b reflects or transmits green light hence they appear green. Carotenoids absorb light in the green - yellow region hence they reflect longer yellow, red, and orange light.

A scientist discovers a cell that has chloroplasts, cytoplasm, DNA, and a cell membrane. Which statement best describes how the

Zina [86]

<span>The correct answer is The cell is eukaryotic because it has chloroplasts. Prokaryotic cells don't have chloroplasts as they are only found in eukaryotic cells. The closest thing there is to chloroplasts are the cyanobacteria who function similarly and also photosynthesize but are in the end not chloroplasts themselves.</span>

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.
