The image below shows part of the surface of a leaf.
0.1 mm x 0.1 mm
The length and width of this piece of leaf surface are both 0.1 mm
Calculate the number of stomata per mm of this leaf surface.
Explanation:
You didn't attach a picture so i'll just explain how to find the number of stomatas/mm^2.
first you find the surface by multiplying the length by the width
0.1*0.1=0.01mm^2
now you count the numer of stomatas in the picture
in0.01mm^2 you have.........................x stomatas
in 1mm you have ...............................y stomatas
y=100x

Answer:
not
Explanation:
If the egg of a particular butterfly has 14 chromosome, then the somatic cells will have same 14 chromosomes.
What are somatic cells?A somatic cell, also known as a vegetal cell, is any biological cell other than a gamete, germ cell, gametocyte, or undifferentiated stem cell that forms the body of a multicellular organism.
These cells make up the body of an organism and divide via binary fission and mitotic division.
Mitosis is a cell division process that produces somatic cells. They have two copies of each chromosome, one from the mother and one from the father. Diploid cells usually have two copies each of each chromosome.
Mitosis is the method by which one cell splits into two genetically identical daughter cells.
The cell's chromosomes are copied and then distributed evenly between the two new nuclei of the daughter cells during the various stages of mitosis.
Thus, as these are somatic cells, they will have same number of chromosomes.

Which type of reproduction is responsible for genetic variation?
Answer:
sexual reproduction
Explanation:
Sexual reproduction results in infinite possibilities of genetic variation. In other words, sexual reproduction results in offspring that are genetically unique. They differ from both parents and also from each other.
Other reproductions like asexual, budding or fragmentation don't produce genetic variation.
The type of reproduction is responsible for genetic variation is - sexual reproduction.
Sexual reproduction is combining genetic information from two individuals, by the fusion of gametes such as sperm and egg, called fertilization which generates more genetic variation, by the process like the combination of alleles and crossing over.
Parents and offsprings are not identical in this reproduction type, however, they are genetically similar.Fusion or combination of two different parent's gametes.There is recombination take place which causes genetic variations as well.Thus, the correct answer that is responsible for genetic variation is - sexual reproduction.
