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)

Peripheral resistance depends on all of the following factors except __________.
pantera1 [17]

Options for the question have not been given. They are as follows:

blood vessel length

blood viscosity

blood vessel diameter

blood colloid osmotic pressure

Answer:

blood colloid osmotic pressure

Explanation:

  • Peripheral resistance is the resistance to blood flow by blood vessels.
  • It is directly proportional to blood vessel length as more the distance to travel, more will be the resistance.
  • It is also directly proportional to blood viscosity as more energy is required to push viscous material.
  • It is indirectly proportional to blood vessel diameter. More the diameter of the vessel, easier it is for the blood to pass.
  • However, it does not depend on blood colloid osmotic pressure. Colloid osmotic pressure is created by the protein components of blood and they do not have any direct impact on blood flow.

Which of the following statements about the development of infectious diseases is correct?
zalisa [80]

The period of Convalescence is the time during which the person regains health and fully recovers.

Explanation:

  • Diseases that can spread from one person to other  are called infectious disease.
  • Disease development is divided into Incubation period, Prodromal period, period of illness, Decline period, and period of Convalescence.
  • During incubation period the pathogen enters the host body and starts multiplying itself. But the signs of diseases are unnoticeable.
  • Then comes  the prodromal period, when the pathogen keeps multiplying itself and some signs of disease are observed but they are not obvious
  • After the prodromal period comes the period of illness when the patient exhibits obvious signs of sickness.
  • As the period of illness is over the symptoms of disease start to cease and the the number of pathogen decrease in body.This period is the period of decline.
  • Finally comes the period of Convalescence when the person returns to his pre-disease state and is completely healthy. (except irreversible damage caused by the disease)

Ann [662]
The answer is <span>d. homologous structures.

Homologous structures are </span><span>similar structures shared by different species. For example, the anatomy of joints in bones of birds and dinosaurs, support the idea that these two groups have a common ancestor. But since these two groups are different enough to be separated into different classes, it can be concluded that they evolved from the common ancestor.</span>
