During her grandfather’s funeral, Emily noticed six individuals walking solemnly beside the casket, gently lifting and carrying it from the church to the hearse, and later to the gravesite. She asked her mother what their role was in the ceremony. What is the correct term for these individuals?

Function Name: alterStrInput:   (char) A vector of lowercase letters containing three words separated by spaces. The last word contains an odd number of characters. The vector of chars contains only lowercase letters and the two spaces that separate the words. Output:   (char) A vector of chars containing three altered “words”. This vector of chars contains only letters and the two spaces that separate the words.Description: Write a function called alterStr that alters the given vector of chars in the following way.    1. The characters in the first word are reversed.    2. All vowels (‘a’, ‘e’, ‘i’, ‘o’, and ‘u’) are removed from the second word    3. The middle character in the third word is changed to uppercase. The output is a vector of characters that contains the altered words separated by spaces. Notes:• A word is a group of adjacent characters either preceded and/or followed by a space.• There will be no spaces at the beginning or at the end of the input string.• Each group of adjacent characters will be separated by only one space. Examples: >> str = ‘two four three’>> a = alterStr(str)a = ‘owt fr thRee’>> str = ‘inky pinky clyde’>> a = alterStr(str)a = ‘ykni pnky clYde’ >> str = ‘larry curly moe’>> a = alterStr(str)a = ‘yrral crly mOe’

How many electrons are needed to produce a charge of -1.23 C on an object?

Two electrons a fixed distance apart, exert an electric force of 2.50 × 10-25 N on each other. What is the distance (units: cm) between these two point charges? NOTE: Use correct rounding and significant figures in the answer Enter numerical answer in proper standard notation, not scientific notation Do not enter units with the answer

Function Name: putItTogetherInput:    (double) A 1×16 vector of numbersOutput:    (double) A 1×4 vector that is constructed from the input vector according to the instructions belowDescription: Write a function called puItTogether that divides the input vector into four 1×4 vectors. Your function then constructs the output vector in the following way.. The first value in the output vector should be the maximum value in the first fourth. The second value of the output vector should be the average of the values in the second fourth rounded to two decimal places. The third value of the output vector should be the second value of the third fourth when it is sorted in descending order. The fourth value in the output vector should be the number of values in the last fourth that are greater than 8. Return the output vector Examples: >> vec = [1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16];>> a = putItTogether(vec)a = 1×4 4.0000 6.5000 11.0000 4.0000>> vec = [7 6 12 14 3 10 8 15 11 5 4 16 1 13 2 9]>> a = putItTogether(vec)a = 1×4 14 9 11 2>> vec = [4 5 13 10 14 8 6 12 16 3 15 9 7 1 11 2]>> a = putItTogether(vec)a = 1×4 13 10 15 1

Function Name: addTimes Input:      (char) A vector of chars that represents an amount of time by showing the number of hours to the left of a colon and the number of minutes to the right of the colon.      (char) A vector of chars that represents an amount of time by showing the number of hours to the left of a colon and the number of minutes to the right of the colon. Output:     (char)  A vector of chars that shows the sum of the two given times. Description: Write a function called addTimes that adds the two given time amounts and shows their sum total time in the following format.   ‘hrs mins’ Notes: The in your output should not exceed 59. Multiples of 60 minutes should be counted as hours. Your inputs are vectors of chars NOT doubles. Your output is a vector of chars that contains digits. For your output, there is a space between the ‘s’ in ‘hrs’ and the number of minutes. Values that are less than 10 do not have leading zeros. Examples: >> aTime = ‘1:30’;>> bTime = ‘1:50’;>> a = addTimes(aTime, bTime)a = ‘3hrs 20mins’ >> aTime = ‘2:45’;>> bTime = ‘1:50’;>> a = addTimes(aTime, bTime)a = ‘4hrs 35mins’ >> aTime = ‘4:59’;>> bTime = ‘0:1’;>> a = addTimes(aTime, bTime)a = ‘5hrs 0mins’

Gene S controls the sharpness of spines in a type of cactus. Cactuses with the dominant allele, S, have sharp spines, whereas homozygous recessive ss cactuses have dull spines. At the same time, a second gene, N, determines whether or not cactuses have spines. Homozygous recessive nn cactuses have no spines at all. A cross between a pure-breeding sharp-spined cactus and a pure-breeding spineless cactus would produce ________.  

How many unique healthy gametes could be produced through independent assortment by an individual with the genotype AaBbCCDdEE?

In cats, black fur color is caused by an X-linked allele; the other allele at this locus causes orange color. The heterozygote is tortoiseshell (cat with both orange and black patches). What kinds of offspring would you expect from the cross of a black female and an orange male?
