The tricuspid valve shuts. This prevents blood from flowing backward into the right atrium while the ventricle contracts. So, your answer will be the Tricuslid Valve. Hope I helped!
A T cell, or T lymphocyte, is a type of lymphocyte a type of white blood cell that plays a central role in cell-mediated immunity.
If a test tube has been used, and its contents is supposed to be disposed, carefully pour the contents to the lavatory with a confirmation of a professional (as it may damage the pipelines of the sink) and ensure that there are no splashes created that can contact the human skin. Wash the test tube thoroughly and let dry.
The correct statements are:
1. The framework of a membrane is a bilayer of phospholipids with their hydrophilic heads facing the aqueous environment inside and outside of the cell and their hydrophobic tails clustered in the center.
2. The diverse proteins found in and attached to membranes perform many important functions.
5. Because membranes are fluid, membrane proteins and phospholipids can drift about in the membrane.
Answer:
From factory emissions to carbon dioxide in the atmosphere (C)
The process occurring can be called Combustion. In this process, organic matter is burned in the presence of oxygen (oxidizer). It releases energy and carbon dioxide because the carbon in organic matter is oxidized to form CO2.
from dead organisms to fossils and fossil fuels (E)
The process explained in the question can be stated as Fossilisation. In this process, dead remains of plants and animals are transformed into fossils under pressure. The organic matter is preserved according to the shape of the organism.
from factory emissions to carbon dioxide in the atmosphere (C) & from carbon dioxide in the atmosphere to photosynthesis (B)
Two reactions represent the conversation of mass and energy. The burning of fossil fuel (mass) releases energy and carbon dioxide, which is again used by plants to store energy in the process of photosynthesis. This is shown in C and B part of the figure
