Answer:
4
Explanation:
According to the question, one box of jello has a mass of 250grams.
The question wants us to find how many boxes of jello would collectively weigh 1kg.
Since the units of weight here are in grams (g) and kilograms (kg), we need to convert to the same unit
1kilogram (kg) is equal to 100 grams (g).
Hence, if 1 box of jello weighs 250g
1000g of jello box will be 1000/250 in number
1000 ÷ 250 = 4.
Hence, 4 boxes of jello will weigh 1000g or 1kg.
Answer:
Neutrophils help fight infections because they ingest microorganisms and secrete enzymes that destroy them. A neutrophil is a type of white blood cell, a type of granulocyte and a type of phagocyte.
Explanation:
Neutrophils display adhesion glycoproteins on their surface to bind endothelial and subendothelial structures. They move randomly until they find a damaged site. Unless neutrophils are activated, endothelial cells do not tend to adhere. When inflammation mediators (IL-1, FNT) activate endothelial cells, they express P-selectin and E-selectin on the surface. The expression of glycoproteins and L-selectin cause the initial adhesion of the non-stimulated neutrophil to the activated endothelium, slowing it down by rolling it over the endothelium. Activated endothelial cells, opsonized particles, immune complexes, FEC-G, FEC-GM and chemoattractants produce factors that stimulate neutrophil activation. Expressing β2 integrin (endothelium adhesion molecule) Neutrophils expand and form pseudopods. Neutrophil activation also promotes degranulation, superoxide generation, and arachidonate metabolite production.
The air and wind is the answer where the word after from
A cell maintains homeostasis through division and repair. The cell cycle has three, stages that are used to help a cell maintain homeostasis. Photosynthesis in a plant cell makes glucose and oxygen for the cell. Then the cell uses that glucose and oxygen to do cellular respiration for the cell to live and function.
