Answer:
(A) Natural killer- virus-infected cell.
(C) Neutrophil - bacteria in skin lesion.
(B) Eosinophil - tapeworm in the intestines.
Explanation:
<u>Natural killer cells</u> are a type of the cytotoxic lymphocyte that are critical to the innate immune system. NK cells are the cells which provide rapid responses to the <u>virus-infected cells</u>.
<u>Neutrophils</u> are type of the phagocyte which are found in bloodstream. During beginning of the acute phase of inflammation particularly which are a result of the <u>bacterial infection</u>, neutrophils are the first-responders of the inflammatory cells to migrate towards inflammation's site.
<u>Eosinophils</u> are variety of the white blood cells which are responsible for combating <u>parasites</u> and also certain infections. Thus it will mostly target <u>tapeworm in the intestine</u>.
Answer: Agriculture is the science or practice of farming, including cultivation of the soil for the growing of crops and the rearing of animals to provide food, wool, and other products.
Explanation:
1) Relying on computers and not going to the field. Sometimes a technical or software fault could lead to a wrong prediction. it could be a new forecaster who does not know the weather patterns and so follows the computer model instead of stepping outside and actually feeling the weather
2) The atmosphere always changes with natural disasters occurring such as pollutants in the air that make forecasting difficult.
3) Most of the times meteorologists base their forecasts on probability. Because of differences in the climate, those temperatures are not the same, so errors occur.
Hope this helps
Answer:
YELLOW
Explanation:
Phenol red is a biological indicator used to monitor changes in pH. The phenol red indicator changes color ranging from yellow to pink with respect to changes in pH. In an acidic pH i.e. <7, the phenol red changes to a YELLOW color while in an alkaline pH i.e. >7, the phenol red changes to a PINK pH.
The presence of carbon dioxide (CO2) increases the hydrogen ion concentration (H+) of a solution (lowering its pH or making it acidic).
Therefore, in a reaction where CO2 is created as a product, it means the CO2 content of that solution increases. Hence, the phenol red solution will be shifting towards the YELLOW color in response to a decreasee in pH (acidic).
