The immune system started to use its antibiotics to battle the infection. It also sent B-Cells to fight the infection while the T-cells kept that immune system strong. The immune system also inflamed the muscles to know where the antigens were so it knew where to kill them

When Anna's immune system was invaded by the s. marcescens infection, the immune system induces pro-inflammatory substance called Cytokinesis.  

<u>Explanation: </u>

Apart from this it initiates the release of protein called as antibodies which are responsible for identification and elimination of disease causing pathogens from the body.  

S. marcescens refers to gram negative bacteria which cause serious urinary as well as respiratory infections. Usually it is found in places such as hospitals, soil and water.

In an investigation, plant cells are placed in water that has been tinted blue. The investigators observe the color of the cells
larisa [96]

Answer:

C

Explanation:

When plant cells take in water, the vacuole swells. A swollen vacuole indicates the plant cell has all the water it needs. This suggests that the plant is taking in water and is maintaining optimum conditions. This is an example of homeostasis.

If the cells burst apart, as in A and E, this would suggest the cell is not properly maintaining homeostasis, as the cell bursting suggests something has gone badly wrong. This suggests the cell has taken in too much water; the cell has not been able to maintain homeostasis and regulate water uptake to prevent this from happening.

In the reverse case, where the cells shrink apart (as in B), the cell would also not be properly maintaining homeostasis by failing to bring enough water into the cell to maintain a turgid state. This is also damaging for the cells.

Finally, D and E can also not be correct, because water can cross the cell membrane, and does not need to be pumped in or sent out by endocytosis.

The diagram below shows the stump of a tree whose root grew into a small crack in bedrock and split the rock apart.
Drupady [299]

Answer:

Physical Weathering

Explanation:

As per the given conditions in the question, the primary effect is <u>mechanical action</u> which is also known as a <u>physical weathering</u>. During mechanical action, a rock is disintegrated into the smaller pieces. In the given statement, <u>the root of tree would grow in the crack and try to develop a strong network to get nutrients necessary for tha tree growth</u>. Thus, the <u>root would exert a pressure</u> in the crack to make more space for its growth and development (root network). This is primarily a mechanical action and an example of physical weathering.

Can clindamycin be used for patient with liver disease
Pie
We administered 300 mg of clindamycin intravenously at 12-h intervals for 2 days to patients with acute and chronic hepatitis, cirrhosis, and controls to determine whether clindamycin will exacerbate preexisting hepatic dysfunction or whether drug excretion will be delayed in patients with liver disease
