Question

What is the range for the following set of measurements? 27°C, 12°C, 31°C, 19°C, 23°C, 11°C, 17°C

Solution 1

The answer is 16. To calculate the range of a set of measurements you are calculating the difference between the highest number and the lowest number. So in this set of measurements the highest number is 31 and the lowest number is 11. To find the difference between numbers, you have to subtract them. If we subtract 11 from 31 we get 20. So, with that being said the range of the following set of measurements is 20.

Question

What is the range for the following set of measurements? 27°C, 12°C, 31°C, 19°C, 23°C, 11°C, 17°C

Solution 1

What is the range for the following set of measurements 27 12 31 19 23 11 17?

11 Degrees C to 31 Degrees C

The range is 20

Solution 2

First order set from least to greatest: 11*C, 12*C, 17*C, 19*C, 23*C, 27*C and 31*C

The highest number is 31*C and the lowest number is 11*C.
Subtract 31-11
And that is: 20*C.

Range- the difference between the highest and lowest part of the set.

Question

Which structure do both nonvascular plants and seedless vascular plants have in common? seeds stems spores

Solution 1

Spores are the structure which are present in both nonvascular plants and seedless vascular plants in common. Thus, the correct option is C.

What are vascular plants?

Vascular plants are also called tracheophytes. These plants form a large group of land plants which have lignified tissues for the conduction of water and minerals throughout the plant and a specialized non-lignified tissue for the conduction of products of photosynthesis.

The seedless vascular plants contain vascular tissue but do not produce flowers or seeds. In seedless vascular plants, like ferns and horsetails, they reproduce through haploid, unicellular spores instead of seeds.

Non-vascular plants do not have any vascular tissues. Non-vascular plants do not possess roots, stems, or leaves which were present in the vascular plants.

Therefore, the correct option is C.
