Answer:
Protein that is made up of 1,160 to 1,400 amino acids.
Explanation:
The Spike protein is a type of protein that is made up of 1,160 to 1,400 amino acids. Different viruses have different amount of amino acids in their spike protein depending upon the type of virus. This spike protein is highly glycosylated and large type I transmembrane fusion protein. Spike protein is a glycoprotein that spreads from the envelope of some viruses which facilitates the virion in entering into a host cell.
Answer: The immune system
Explanation:
The immune system is a complex network of proteins and cells that defends the body against infection or any invasion. The human defense system in the body is actually made up of entire organs and vessel systems like the lymph vessels. The immune system is made up of organs that control the production and maturation of certain defense cells.
Initially, all living things are subjected to attack from disease causing agents. Even bacteria, so small that more than a million could fit on the head of a pin, have systems to defend against infection by viruses. This kind of protection gets more sophisticated as organisms become more complex.
A statement of cause and effect that can be used to set ip a test for a hypothesis is called a prediction.
The list of items are as follows:
day length,
tundra plants, including blueberries and birch
caribou and grizzly bear
soil depth
lichens
air temperature
Answer:
The correct answer is - tundra plants, including blueberries and birch, caribou and grizzly bear, and lichens.
Explanation:
The arctic tundra is known for its extremely cold winter temperatures, high latitude/northern hemisphere, little precipitation. Vegetation in here is permafrost, birch, blueberries, lichens, and mosses, migrating mammals such as grizzly bears and caribou, and residing herbivores.
Various biotic and abiotic factors interact in this ecological community one another and on the basis of the given information the items which are part of the arctic tundra ecological community are-
tundra plants, including blueberries and birch, caribou and grizzly bear, and lichens.
