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

North component: y = 15.0 m * sin 55.0º = 12.3 m West component: x = 15.0 m * cos 55.0º + 7.00 m = 15.6 m 
so his heading, measured from West, is Θ = arctan(y/x) = arctan0.787 = 38.2º N of West 
and measured from North is φ = arctan(x/y) = arctan(1.27) = 51.8º W of North 
Hope this helps!

What trends do you see in theorganisms of the ecosystem ifyou decrease CO2?
Maru [420]

Question:

Solution (explanation):

Within an ecosystem, we can find photosynthetic organisms such as plants. The general chemical reaction for photosynthesis is 6 carbon dioxide molecules and 6 water molecules, with the addition of solar energy. This produces 1 glucose molecule and 6 oxygen molecules. Therefore, if one of the reactants of the photosynthetic reaction, namely carbon dioxide, decreases, the amount of glucose (energy storage molecules) will decrease. Remember that energy storage molecules include glucose, starch, and fat.

Answer: we can conclude that the correct answer is:

Decrease in energy storage molecules.

Bas_tet [7]

Answer:

The question is incomplete but the complete question is attached in image format with options and the correct answer according to the data given in it is - option B. The optimum habitat for the golden-cheeked warbler population in 100 juniper trees per acre .

Explanation:

The provided data with the question helps to establish that the population interaction between a golden-cheeked warbler and the juniper tree are interdependent. The population of the warbler is increased with the increase in the population of juniper tree up to 100 juniper trees per acre.

The further increase in the population of the juniper tree affects negatively and there is a decrease in the population of the warblers.

Thus, the correct answer is -  option B. The optimum habitat for the golden-cheeked warbler population in 100 juniper trees per acre .

What characteristics of skin make it unpleasant for most bacteria?
Svetach [21]

Answer:

a. All of these

Explanation:

<em>The characteristic of skin that makes it unpleasant for most bacteria would be due to all of the conditions.</em>

Most bacteria require humid condition in order to grow and as such, the desiccated nature of the normal human skin makes it difficult for them to establish themselves and grow on it.

The pH of the skin is usually acidic due to the production of lactic acid during sweating and the activities of the normal skin bacteria. The acidic pH hinders the growth of bacteria that can potentially become pathogenic to the skin.

Also, the skin produce antimicrobial substances at low pH which hinders the growth of pathogenic bacteria.

Hence, options b, c, and d are correct.
