What is a protein that is able to distinguish between a foreign protein or cell?

Answers

Answer 1

Answer: MHC Protein
The major histocompatibility complex (MHC) is a set of cell surface proteins essential for the acquired immune system to recognize foreign molecules in vertebrates, which in turn determines histocompatibility. The main function of MHC molecules is to bind to peptide fragments derived from pathogens and display them on the cell surface for recognition by the appropriate T-cells.[1] MHC molecules mediate interactions of leukocytes, also called white blood cells (WBCs), which are immune cells, with other leukocytes or with body cells. The MHC determines compatibility of donors for organ transplant, as well as one's susceptibility to an autoimmune disease via cross reacting immunization. In humans, the MHC is also called the human leukocyte antigen (HLA).

What is an example of a simple protein found in eggs?

Answers

A protein,such as a globulin or histone, that yields only amino acids upon hydrolysis.

Most of the proteins in egg yolks have lipoproteins. The lipoproteins are divided into two groups: a plasma and a granule fraction. The granule portion has a phosphoprotein, that is 54% serine. Serine is a amino acid that can act as a carrier of calcium or iron ions in biological systems.

volume: cubic meter
mass: grams
temperature: celsius

A candle and a firework both can be ignited with a spark, but they release different amounts of energy as they burn. Compare and contrast the potential energy diagrams that would represent each of these burning processes.

Answers

The reactions of both candle and firework is exothermic. This means that the products have a lower potential energy than the reactants. The difference is that fireworks release more energy than the candle. In the energy curve diagrams, the fireworks will begin with a more potential energy.

What are some ways each person could reduce air pollution and energy consumption?

Answers

some ways each person could reduce air pollution and energy consumption are :
- Adjust temperature settings, cooler in winter and hotter in summer

- Using Electric based vehicles

- Turn off your electicity when you're not using it

hope this helps

The ways in which an individual could reduce air pollution is that he or she can use public transport in spite of going by their own vehicle.

He can use electrical techniques in the place of burning fossil fuel.

Energy consumption: The amount of energy utilized by an individual can be reduces if the energy is not wasted and used in a proper way.

He must switch of the lights and fans when they are not in use.

He can use solar alternatives to save energy.
