Answer:
MHCI
Explanation:
Major histocompatibility complex I (MHCI) is present on the nucleated cells of the body. Endogenous pathway represents the pathway of MHC class I molecules.
MHCI display peptide fragment of proteins to the cytotoxic T cells with the help of CD8 ( Cluster of differentiation). CD8 binds with the MHCI and expressed on the surface of cytotoxic T cells.
Thus, the correct answer is option (D).
Answer:
A. vital capacity
Explanation:
<u>Vital capacity is defined as maximum amount of the air that a human can expel from lungs after the process of maximum inhalation. In other words, its is the volume of the lung which represents the maximum of the total volume which can be exchanged with the air.
</u>
It can be measured by using a wet or a regular spirometer. A normal adult has between 3 to 5 litres of VC. Vital capacity of the human depends on the age, sex, mass, height and ethnicity.
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
Explanation:
The answer is D. in animal cells, the cell membrane allows materials in and out of the cell, while the mitochondria uses nutrients to make energy (ATP) for the cell.
