Answer:

H. Mantle

Explanation:

Convection currents are identified in Earth's mantle. Heated mantle material is shown rising from deep inside the mantle, while cooler mantle material sinks, creating a convection current. It is thought that this type of current is responsible for the movements of the plates of Earth's crust.

den301095 [7]

Complete question:

Phenotype               Genotype         Number of Individuals

Long-tailed                     TT                               260

Long-tailed                      Tt                                160

Short-tailed                      tt                                 80

If 20% of the long-tailed cats got their tails stuck in something and failed to reproduce, what would be the expected change in frequency of T in the next generation

Answer:

The expected change in allelic T frequencies probably changes from 0.6 to 0.57 in the following generation.

Disscus the importance of phytoplankton to the composition of the earth's atmosphere?​
Evgesh-ka [11]

Answer:

Phytoplankton are essential for atmospheric and climate regulation.

Explanation:

Phytoplankton are autotrophs, they use solar energy, along with inorganic carbon and water to produce their own food source via photosynthesis. During photosynthesis, they also produce oxygen, integral for the planet's atmospheric composition.

At their large biomass, phytoplankton contribute to a majority of the oxygen used by consumers (most animals).

             6 CO2 + 6 H2O + light  →  C6H12O6 + 6 O2

Carbon Dioxide + Water + Light       Glucose + Oxygen

Along with fossil fuels, human agricultural practices have contributed large amounts of CO2 to the atmosphere, This causes global warming, a major environmental crisis- global warming also leads to landmass loss, biosphere disruption and reduces biodiversity in mass extinction events.

Phytoplankton carbon cycling produces organic matter which functions as carbon sinks in our oceans. Thus, as phytoplankton use large amounts of CO2, they help combat warming cycles, along with producing O2 in atmospheric and climate regulation.

Contact [7]

According to the research, the correct answer is fiber composites. Because cell walls consist of a cross-linked network of long filaments embedded in a stiff surrounding material, they can be called fiber composites.

<h3>What are cell walls?</h3>

It is a network that covers prokaryotic cells and plant cells that is located outside the plasma membrane, helping to form the structure.

In this sense, since it is made up of a network of carbohydrates, phospholipids and structural proteins, and the different cell types of plants can be identified by their characteristics, they can be called fiber composites.

Therefore, we can conclude that cell walls are a network embedded in a matrix composed of carbohydrates and proteins.

During what set of reactions is oxygen released?
sashaice [31]

In a series of reactions the energy is converted (along an electron transport process) into ATP and NADPH. Water is split in the process, releasing oxygen as a by-product of the reaction.
