The structure of the skin is an effective barrier against bacteria. The multiple layers of epidermis, while can be invaded by foreign organisms, has a high turnover rate which means it is constantly shedding, therefore even the bacteria is shed protecting the body. Lastly, the skin's lipids maintain an acidic pH which slows and stops growth and replication of bacteria.
There are around 350,000-600,000
Answer:
Choose distinct parallel lines.
Explanation:
They represent two parallel lines. The slopes are going to be the same in each line . Put the x value on the opposite side of the equal sign.
y = - 5x + 3 The slope is - 5
10x + 2y = - 6 Subtract 10x from both sides
2y = - 10x - 6 Divide by 2
y = -10x/2 - 6/2
y =-5x - 3
That minus three is the problem. You have 2 different y intercepts. That means that you have 2 parallel lines.
Answer:
Option 3, of the abiotic factors found in their environment
Explanation:
The abiotic factors such as absence of sunlight and extremely cold temperature represents picture of an extreme habitat under an ice shelf in Antarctica.
The optimum temperature requirements of bacteria for its survival ranges from 10oC to 20oC. In case, if a bacteria lives in an environment where temperature is less than -5oC or higher than 50oC, then such habitats are considered to be “habitats with extremities” as special physiological mechanisms are required to maintain the homeostasis and survive.
Likewise absence of sunlight further adds to the extremities of the habitat.
Option 3, is correct
It form the contraction and relaxation of muscle
