What is the main function of the Rough Endoplasmic Reticulum?

Which feature distinguishes Gram-positive bacteria from Gram-negative bacteria?

What happens during exocytosis?

Which scientists proposed that all organisms are made of one or more cells?

What is the role of ribosomes in the cell?

What is the structure of the cell membrane?

1. What is the function of the cytoskeleton?

What is facilitated diffusion

1. You observe a cell under a microscope and notice that it has a nucleus and several membrane-bound organelles. Based on these features, what type of cell is it?

A plant placed in a container of saltwater begins to wilt as water leaves its cells. Which process explains this observation?

A scientist sees that a bacterial cell has a hard outer layer What does this layer do?

A teacher says that all living things are made of cells and that all cells come from other cells. Why is this idea important?

1. A sugar molecule moves into a cell through a protein from an area of high concentration to low concentration without using energy. What type of transport is this?

1. A cell uses energy to move sodium (Na⁺) out and potassium (K⁺) into the cell against their concentration gradients. What type of active transport is this?

What do you call an ordered series and precisely timed events involving cell growth, DNA replication, and cell division that produces two identical (mitosis) or non-identical (meiosis) cells?

1. During this phase, the replicated DNA and cytoplasmic contents are separated, and the cell divides. What phase of the cell cycle is this?

The cell's DNA is replicated, ensuring each daughter cell receives a complete set of genetic information. Additionally, histones and other proteins necessary for DNA packaging and replication are synthesized. What phase of the Interphase is this?

What occurs in somatic cells (body cells e.g. bones, blood, skin) that results in two daughter nuclei that are also genetically identical to the original parent nucleus?

What only occurs in sex cells (gamete) employs many of the same mechanisms as mitosis. However, it undergoes two processes of division that results in genetically unique daughter cells?

1. What do you call the process of cell division that occurs without regulation, leading to formation of a tumor and potentially cancer?

1. Proto-oncogenes are present in our body to regulate cell growth. What do you call If these genes mutate, that increases the chance of a normal cell to develop into a tumor cell?

What is the stage of cell division (mitosis or meiosis), where chromatin condenses into visible, X-shaped chromosomes, the nuclear envelope breaks down, and the mitotic spindle begins to form to separate them later?

What is one of the crucial stages in cell division (mitosis and meiosis) where duplicated chromosomes, now highly condensed, line up along the cell's equator, known as the metaphase plate, preparing to separate into two new daughter cells; spindle fibers attach to kinetochores on each chromosome, ensuring they are evenly positioned for separation in the next stage?

What is the stage of  cell division (mitosis & meiosis) after the process of metaphase, when replicated chromosomes are split and the newly-copied chromosomes are moved to opposite poles of the cell?

What is the final stage of cell division (mitosis & meiosis) where chromosomes arrive at opposite poles, a new nuclear membrane forms around each set, and the chromosomes uncoil back into chromatin, essentially reversing prophase; it's immediately followed by cytokinesis, which divides the cytoplasm and organelles into two separate daughter cells?

What is a genetic error that can occur in both mitosis and meiosis. Is it a failure of chromosomes or sister chromatids to separate properly during anaphase, leading to daughter cells with an incorrect number of chromosomes (aneuploidy)?

Chromosomal Aberrations are a change in the structure or number of a chromosome, which can lead to genetic disorders. These abnormalities are categorized as either numerical (involving too many or too few chromosomes) or structural (involving a change in a chromosome's physical structure). Which of the following DOES NOT fall under this category?

What term is used to describe the absence of one member of a pair of chromosomes, wherein, there is a total of 45 chromosomes in each cell of the body, rather than 46?

Deletion refers to the loss of a portion of one chromosome. When this chromosome is passed onto offspring the result is usually lethal due to missing genes. Which of the following describes Deletion?
