A Carbon Sink is a reservoir which absorbs more carbon than it releases. Suggest how carbon in the bodies of crustaceans and mol

mr Goodwill [35]

Answer:

Crustaceans and Molluscs play an important role in the oceanic carbon sink.

Explanation:

Carbon sinks can serve to partially offset greenhouse gas emissions. Forests and oceans are both large carbon sinks. Algae is pressurized to bottom of the ocean by long term sequestration. Algae then falls to the bottom of the ocean and TRANSFORMS to fossil fuels.

CO2 is not combustible.
creates carbonic acid in the oceans.
Reduces seawater pH, carbonate ion concentration, and thus calcium carbonate (needed for shells for marine creatures, contributes to BOTTOM-UP EFFECT)

aalyn [17]

Aerobic respiration is the release of energy from glucose or another organic substrate in the presence of Oxygen. Strictly speaking aerobic means in air, but it is the Oxygen in the air which is necessary for aerobic respiration. ... ATP can provide energy for other processes such as muscle contractions.

A particularly long radio wave has a wavelength of 1.5 x 10^9 meters. What is the frequency of this radio wave?

Phoenix [80]

Answer:

0.2Hz

Explanation:

The wavelength of a radiowave can be calculated this;

λ = v/f

Where;

λ = Wavelength (m)

v = speed (m/s)

f = frequency (Hz)

Based on the information provided in this question, λ = 1.5 x 10^9 meters, c = 3 × 10^8m/s, f = ?

Hence, using λ = v/f

f = v/λ

f = 3 × 10^8 ÷ 1.5 x 10^9

f = 2 × 10^(8-9)

f = 2 × 10^-1

f = 0.2Hz

Whats the difference between genotype and phenotype.

Olegator [25]

$\huge{\green}\fcolorbox{blue}{cyan}{\bf{\underline{\red{\color{red}Answer}}}}$

The genotype is a set of genes in the DNA which are responsible for the unique trait or characteristics.
Whereas the phenotype is the physical appearance or characteristic of the organism.
Thus, we can find the human genetic code with the help of their genotype.
Organisms may look the same but still may not have the same genotype.
One can determine the genotype by the biological tests.
On the other hand, the phenotype is determined by an individual’s genotype and can be expressed as genes or by the visible traits.
Such traits are hair color or type, eye color body shape, and height, and many such more.
It will depend on the genotype but also influenced by the factors existing in the surrounding.
