crimeas [40]3 years ago
3 0

Answer:

Both are made of microtubules

Explanation:

Cilia and flagella are locomotory projections on a cell covered by plasma membrane. They are both made of microtubules. They are designed to move the entire cell or move substances. In the respiratory epithelium, the free end of the cells has hair-like structures called cilia which propel mucus and dust particles along it.

Consider this microscopic image of bacteria. mc005-1.jpg Which bacterial shape is shown in the image?
e-lub [12.9K]

The right answer is spiral.

Size and shape vary from one bacterium to another. The majority of bacteria have a size between 0.5-5 μm in diameter.

Most bacteria are either spherical or rod-shaped. In the first case they are called cocci (of the Greek kókkos, grain) and in the second bacilli (of Latin baculus, rod). There are also intermediate forms: coccobacilli. Some rod-shaped bacteria are slightly curved like vibrio. Other bacteria are helicoidal. They are spiral if the form is invariable and rigid, spirochaetes if the body is flexible and can change shape.

The decimal reduction time (DRT) to kill 90% of cell present for autoclaving a culture is 1.5 minutes. How long would it take to
-BARSIC- [3]

Answer:

10.5minutes

Explanation:

DRT = 90%

Cells present = 10^6

Autoclaving = 1.5 minutes

Solution:

10^6(1.5)10^5(1.5)10^4(1.5)10^3(1.5)10^2(1.5)10^1(1.5)10^0(1.5)0=10.5

it would take it approximately 10.5 minutes to kill 10^6 of the cells.

If i should stop the heating process at 9 minutes this would have effect on some of the microbes as they are still present with 1 bacterium left which makes it not efficient.
