You are playing a new video game that is based on the human immune system. The player is inside a human, and you must successful

ly fend off invading pathogens in a quest to find the "Golden Antibody." At level 1, your arsenal for fighting off pathogens consists only of the innate immunity leukocytes and their various secretions. If the enemy has killed off most of your neutrophils and macrophages, which of the following should you utilize to recruit more of these leukocytes to the battle? A Histamine B Platelets C. Reactive oxygen species D. CytokinesE. Bone marrow

Answer:

D. Cytokines

Explanation:

I would utilize Cytokines to recruit more leukocytes to the battle.

Cytokines are important chemical messengers that act via receptors in the immune system of the body. They are a group of proteins made by various immune cells. Immune cells communicate through Cytokines in regulating immune response

Dead animals and plants and wastes
Margarita [4]
An ecosystem involves both the biological (plants, animals, human beings) and non-biological (land, water, soil, and atmosphere) community which interacts as a system. More importantly, the living things are very dependent on the abiotic community since it cannot survive by itself. Every animal, plant and human needs the primary physiological needs of water, food and shelter provided by the abiotic system.

Describe how the role of phloem would would be affected if the leaves start to die off
Naya [18.7K]
The conductive tissues of the angiosperms are the xylem which drives the raw sap and the phloem which conducts the elaborate sap.The phloem, or liber, drives the elaborate sap, solution of organic substances rich in carbohydrates, from the leaves to the other organs.

The elaborate sap (which contains organic substances produces by photosynthesis) is produced in the leaves, where the majority of the chlorophyll subsist, so if the leave die off, the production of organic substances and the elaborate sap are reduced, so its transport by the phloem will be reduced, and this is how the phloem will be affected by the dying of the leaves.

What is the formula for this compound?
Delicious77 [7]

Answer:

Symbols: Each capitol letter means that there is a new element

Li2

Cl3

is made of lithium and chlorine

Na2

SO4 is made of sodium, sulfur and oxygen

Chemical Formulas are used to describe a chemical compound, when two or more atoms

combine to form a new substance.

A combination of chemical symbols shows the elements that make up a chemical compound.

The chemical formula for water is H2O

H stands for HYDROGEN.

O stands for OXYGEN.

Subscripts are numbers that come after a symbol and below. Subscripts tell you the number of

atoms of that element. If an element does not have a subscript, then it is understood that the

subscript is 1.

Li2Cl3 has two lithium atoms and three chlorine atoms

Na2SO4 has two atoms of sodium, one atom of sulfur, and four atoms of oxygen

A subscript outside a parenthesis affects all the elements inside the parenthesis. Multiply the

subscript on the outside by the subscript of the atoms on the inside.

Al (SO4)3 has 1 atom of aluminum, 3 atoms of sulfur, and 12 atoms of oxygen.

Coefficients are full size numbers in front of chemical formula. The coefficient multiplies everything

in the formula. It also represents the number of molecules of that compound.

2Na2

SO4 has 4 sodium atoms, 2 sulphur atoms, and 8 oxygen atoms.

2Al (SO4)

3 has 2 aluminum atoms, 6 sulfur atoms, and 24 oxygen atoms

When you count atoms, remember to multiply the coefficient number and the subscript number to find

the number of atoms of that element.
