How many haploid chromosomes are found in black mulberry (Morus nigra) gametes? (Please enter a number from 2 - 500.)
Correct Answer
154
Explanation
Black mulberry (Morus nigra) is a diploid plant species, meaning it has two sets of chromosomes. In gametes, which are reproductive cells, only one set of chromosomes is present. Therefore, the number of haploid chromosomes in black mulberry gametes is equal to the number of chromosomes in one set, which is 154.

What is the highest number of diploid chromsome number for Coffea arabica?
Correct Answer
D. 88
Explanation
Coffea arabica is a species of coffee plant, and the highest number of diploid chromosome number for this species is 44. Since diploid means having two sets of chromosomes, the highest number would be double that, which is 88.
8.
What is the chromosome number in sperm cells of a donkey (Equus asimus)?
Correct Answer
C. 62
Explanation
The correct answer is 62 because donkeys, like most mammals, have a diploid chromosome number of 62. This means that each somatic cell in a donkey's body contains 62 chromosomes, with half coming from the mother and half from the father. However, sperm cells are haploid, meaning they only contain half the number of chromosomes as somatic cells. Therefore, the chromosome number in sperm cells of a donkey is 62.
9.
What is the common name for Vulpes vulpes crucigera?
Correct Answer
B. Fox
Explanation
The common name for Vulpes vulpes crucigera is "Fox". This is the correct answer because Vulpes vulpes crucigera is the scientific name for the red fox, which is a common species of fox found in North America. The common name "Fox" is widely used to refer to this animal.
10.
Each of the following species have total number of 48 chromsomes in their somatic cells, except for one. Which species has more than 48 chromosomes?
Correct Answer
D. Honey bee
Explanation
The honey bee has more than 48 chromosomes. This is because the question states that all the species listed have a total of 48 chromosomes in their somatic cells, except for one. Therefore, the honey bee must have a higher number of chromosomes than 48.
11.
Hydra vulgaris has (lower, same, higher) number of diploid chromosome number as humans.
Correct Answer
lower
Explanation
Hydra vulgaris has a lower number of diploid chromosome number compared to humans. This means that Hydra vulgaris has fewer pairs of chromosomes in its cells compared to humans. Chromosomes carry genetic information and determine various traits and characteristics. The difference in chromosome number between Hydra vulgaris and humans suggests a variation in their genetic makeup and evolutionary history.
12.
How many chromosomes are found in the Pisum sativum unfertilized ovum? (Please enter a number from 1 - 100.)
Correct Answer
7
Explanation
The Pisum sativum unfertilized ovum contains 7 chromosomes.
13.
How many chromosomes are found in the sex cells of a male Mus musculus?
Correct Answer
B. 20
Explanation
Male Mus musculus, commonly known as a mouse, has 20 chromosomes in its sex cells. Sex cells, also known as gametes, are sperm cells in males. These cells are responsible for carrying genetic information to the offspring during reproduction. In mice, like many other mammals, the sex cells contain half the number of chromosomes compared to other cells in the body. Since the question specifically asks about the sex cells of a male Mus musculus, the correct answer is 20 chromosomes.
14.
How many diploid chromosomes are found in these organisms; hyacinth, newt, common oak, and scarlet oak? (Please enter a number from 1 to 100.)
Correct Answer
24
Explanation
The answer is 24 because diploid organisms have two sets of chromosomes, one from each parent. The number 24 suggests that each of the mentioned organisms has 12 pairs of chromosomes, totaling to 24 individual chromosomes.
15.
How many different diploid number of chromosomes are found for the Sus scrofa?
Correct Answer
D. 4
Explanation
The diploid number of chromosomes refers to the total number of chromosomes found in a cell nucleus, where each chromosome is present in pairs. The answer to this question is 4 because Sus scrofa, also known as the domestic pig, has a diploid number of 38 chromosomes. Therefore, when counting the pairs, there are a total of 4 different diploid numbers of chromosomes in Sus scrofa.
16.
What is the chromosome number found in Solarnum tuberosum sperm cells?
Correct Answer
D. 24
Explanation
The correct answer is 24 because Solanum tuberosum, commonly known as the potato, is a diploid organism with 24 chromosomes. This means that its sperm cells, like other cells in its body, will also contain 24 chromosomes.
17.
Porpoise has (less, same, more) diploid chromosomes than Rhesus monkey.
(NOTE: Please enter your answer in all lower case letters.)
Correct Answer
less
Explanation
Porpoise has fewer diploid chromosomes than Rhesus monkey. This means that the number of chromosomes in the cells of a porpoise is lower than the number of chromosomes in the cells of a Rhesus monkey.
18.

How many diploid chromosomes are found in Saccharum officinarum? (please enter a number from 1 - 300.)
Correct Answer
80
Explanation
Saccharum officinarum, commonly known as sugarcane, has 80 diploid chromosomes. This means that in each cell of Saccharum officinarum, there are 80 chromosomes arranged in pairs. Diploid chromosomes refer to the complete set of chromosomes in a cell, with each chromosome having a corresponding partner. Therefore, the correct answer is 80.
20.
