Match the following to their correct definitions

Draggable emne		Korresponderende emne
Crossing over		The process during meiosis results in the random distribution of chromosomes to gametes.
Chromosome reduction		The process that lead to genetic diversity and it ensures the survival of a species.
Independent assortment		The process which the chromosome number is reduced to ensure that each child receives a complete set of chromosomes.

Identify whether the following statements belong to Meiosis I or Meiosis II.

The separation of homologous pairs occurs
Separation of sister chromatids occurs
Crossing over/Recombination

Determine the most accurate explanation of meiosis and clarify how this process guarantees that the resulting gametes contain haploid(half) number of chromosome.

Meiosis randomly chooses which chromosomes to retain, resulting in each genetically distinct gamete possessing a unique number of chromosomes.

Meiosis involves a single division process, producing two daughter cells that are genetically identical to the parent cell and maintain the same chromosome count.

Meiosis consists of two cycles of cell division, leading to four genetically unique daughter cells, each containing half the chromosome count.

Meiosis involves the duplication of chromosomes without dividing them, resulting in the formation of four genetically identical gametes, each containing the complete set of chromosomes.

Which process describes how cells can produce different proteins despite having identical DNA?

Selective gene activation through enzyme control

Random selection of genes

Complete expression of all genes

DNA mutations at random

What is the primary characteristic of stem cells that makes them unique?

They can only divide once

They can differentiate into various cell types

They are found only in adult tissues

They cannot reproduce themselves

Two daughter cells are created at the end of each stem cell division. One of these daughter cells will continue to function as a stem cell, while the other will develop into a specialized type of cell.
What will most likely influence the kind of specialized cell that will be generated as they mature?

The amount of time spent in the cell cycle

The amount of genes found in the cell

The type of genes that are expressed (active) in the cells

The number of chromosomes that are replicated

The diagram shows how specialized body cells develop.
Which of the following best explains why cells that contain the same genetic material do not develop into the same types of cells?

Random mutations may arise in the DNA of cells during the initial stages of embryonic development.

Environmental stimuli can influence gene expression by activating or deactivating particular genes within the DNA of cells.

Cells compete for nutrients and that's why they look different

DNA sequences change over time causing the cells to not develop into the same type of cells
