1. Cones perceive light in color while rods perceive light in black and white.

2. Rods can perceive dim light, unlike cones. The rods are located at the edges of the eyes. This is why it easier to perceive an image in the dark through the corner of the eyes.

3. The discs that compose the cones are usually partially open to the surrounding vitreous fluid while those of the rods are closed.

Answer:

The average number of days is more than 43% from the past 8 years is 43.15 days and it is less than Sample mean of 47 for 20 samples

Explanation:

From the data

Population mean = μ=43 days

Population variance= $\sigma^2$ =196

$\sigma=\sqrt{196}=14$

Sample size n=20

Sample mean $\bar{x}$ =47

Part a:

Using values from the reference question found online.

Given α=43%

α=0.43

At 1-α=0.57

$z_{\alpha}$ from the table yields 0.18

Now the value is given as

$\bar{x}=\mu+z_{\alpha}\sqrt{\frac{\sigma}{n}}\\\bar{x}=43+0.18\sqrt{\frac{14}{20}}\\\bar{x}=43.15 days$

Part b:

Sample mean of 47 for 20 samples is more than 43% of the days from last 8 years.

Triss [41]

Given what we know, two common medical or biological conditions that may create a hazardous environment when working in a microbiology lab are asthma and working with an infectious disease that may become airborne.

<h3>Why would these conditions prove hazardous?</h3>

Working with chemicals and microbes can be especially hazardous to individuals with asthma.
This is due to the strong effect that certain chemicals can have in triggering an asthma attack.
Microbes may also cause upper respiratory tract infections if breathed in, further worsening asthma.
Likewise, working with an infectious disease that has the capability to be airborne is especially hazardous given the ease with which one may become infected and transmit the disease.

Therefore, we can confirm that two common medical or biological conditions that may create a hazardous environment when working in a microbiology lab are asthma and working with an infectious disease that may become airborne.

Why does earth turn so slowly?

Butoxors [25]

Answer: Earth's rotation is slowing slightly with time,thus, a day was shorter in the past. This is due to the tidal effects the Moon has on Earth's rotation. Atomic clocks show that a modern-day is longer by about 1.7 milliseconds than a century ago.
