NAME:
1) Review the information below:
I. Organisms that grow by increasing the size of a single cell are called unicellular.
II. Multicellular organisms grow primarily by increasing the number of cells in the body.
III. The cells grow until they reach a certain size, and may or may not divide into two smaller cells, fundamentally similar to the original.
IV. In the case of unicellular beings, the division of cells in two corresponds to the reproduction process itself.
Which of the above statements are correct:
a) I, II, III and IV
b) I and II
c) II and IV
d) I, II and IV
2) The ________________ is an essential characteristic of life and is closely linked to reproduction. When a living being reproduces, it transmits to its descendants a set of instructions in code, inscribed in the genetic material. The alternative that adequately fills the information gap above is:
a) Heredity
b) fertilization
c) Reproduction
d) Self-fertilization
3) Relate properly:
1. Asexual reproduction – 2. Sexual reproduction – 3. cross fertilization
4. Gametes – 5. Zygote – 6. Fertilization – 7. self-fertilization
( ) When gametes that fuse and originate from two parental individuals.
( ) Process of union of gametes.
( ) When gametes come from the same parent.
( ) Occurs when a new being arises from a single cell.
( ) When a new being arises from a cell or a group of cells produced by a single parental being.
( ) Specialized cells that are responsible for the transmission of genes from one generation to the next during the process of sexual reproduction.
( ) It is the cell resulting from the union of the male and female gametes, in a stage prior to cell division.
4) The genetic instructions are present in molecules of a chemical substance called:
a) Deoxyribonucleic acid (DNA)
b) Ribonucleic Acid – RNA
c) Cyclic acid
d) folic acid
5) Answer in your own words what genetic variability consists of:
