Identify and describe the main components of the carbon cycle.

olya-2409 [2.1K]

The carbon cycle is the biogeochemical cycle by which carbon is exchanged among the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of the Earth. Carbon is the main component of biological compounds as well as a major component of many minerals such as limestone hope this helps you pls thank me

How does photosynthesis start?

Basile [38]

Photosynthesis starts when a photon- a tiny packet of light is absorbing a molecule of chlorophyll.

The concentration of N2 in blood at 37 °C (body temperature) and atmospheric pressure (partial pressure of N2 = 0.80 atm) is 0.0

devlian [24]

Answer:

volume = 0.285 L

Explanation:

Henry constant is given as

$Henry constant = \frac{C}{P}$

Where C is concentration

P is atmospheric pressure

$Henry\ constant = \frac{0.00056}{0.80} = 0.0007 M/atm$

when atmospheric pressure 4 atm

$solubility = K_H\times P$

$= 0.0007 \times 4 = 0.0028 M$

In 5 litere blood , moles of N_2 $= Molarity \times volume$

$= 0.0028 \times 5 = 0.014$

At surface moles $= 0.0056 \times 5 = 0.0028$

Moles of N_2 release = 0.014 - 0.0028 = 0.0112

Mass of $N_2 = 0.0112 \times 28 = 0.314 g$

T = 37 + 273 = 310 K

$VOLUME = \frac{nRT}{P}$

$= \frac{0.0112\times 0.0821\times 310}{1}$

volume = 0.285 L

why the Eukarya domain includes more complex living things than the Archaea or Bacteria domains? A. All prokaryotes are unicellu

kykrilka [37]

Answer:

The correct answer is C eukaryotes have a greater variety of genetic material than prokaryotes.

Explanation:

Prokaryotic cells consist of single chromosome and their DNA is present in a dense region called nucleoid.As one copy of each gene is present in the chromosome prokaryotic cells are haploid.The DNA of prokaryotic cells are circular

Whereas eukaryotic DNA is linear and multiple distinct chromosomes are present in eukaryotes.Two copies of each chromosome are present are in many eukaryotic cells.As a result the eukaryotic cells are diploid in nature.

Due to this greater variety of genetic material the domain eukarya are more complex than archea and or bacteria domains.
