The width of a red blood cell is approximately 8 micrometers, which is 8 x 10-6 meter. give your answers to the questions below in scientific notation. be sure to answer both a and b, and explain your answer to b.

a. what would be the width of 7.2 x 105 red blood cells in meters?

b. if a grain of salt is .5mm wide, how many red blood cells could fit across one grain of salt? explain your answer. (hint: 1mm = 1 x 10-3 m.)

A)  

B)  62

Step-by-step explanation:

The width of a red blood cell is approximately 8 micrometers meters

Part A)

Width of 1 red blood cell meters

width of red blood cells meters

Now change into scientific notation. So, decimal should be between 1 to 10

Decimal move 1 digit right to left

Hence, the width of red blood cells is

Part B)

If a grain of salt is 0.5 mm wide.

First convert mm to m. ( 1 mm = 1 × 10⁻³ m)

Therefore, 0.5 mm = 5 × 10⁻⁴ m

Size of a grain = 5 × 10⁻⁴ m

Size of a blood cell = 8 × 10⁻⁶ m

Hence, 62 number of red blood cells fit in a grain of salt.

the population of other specie of birds will decline or other specie of birds will find some alternate source of food to survive.

explanation:

according to the competitive exclusion principle, which is also known as gause's law, two specie living in the same niche and feeding on the same resource cannot co-exist stably.

as we have well studied the theory of natural selection which states that only those organisms survive which have better tendency to compete for food and adapt to the environmental conditions.

coming towards the question, what wi ll happen when one species outcompetes the other for the small fish , the other specie will not get enough food and will start to die or decline in population. eventually either other specie needs to find another alternative food source for itself or migrate at some other location where there is less competition otherwise it will just not exist anymore at that niche.

hope it !
