What do skin brain heart and lung cells look like?
You will need to chick on these links to see the differences between heart, skin. brain and lung tissues.
Is each cell ball-shaped?
Not all cells are ball-shaped; they come in various shapes depending on their function and type. For example, red blood cells are typically disc-shaped, while neurons have long, branching structures. Bacteria can be spherical (cocci), rod-shaped (bacilli), or spiral (spirilla). The shape of a cell is often adapted to its specific role in an organism.
What is branching factor in trees?
In computing, tree data structures, and game theory, the branching factor is the number of children at each node
Does a hickory tree have opposite branching?
No, hickory trees do not have opposite branching. They exhibit alternate branching, where the branches are spaced alternately along the stem rather than directly across from each other. This growth pattern is typical of many tree species.
How are dichotomous keys and branching key diagram different?
Dichotomous keys use a series of questions with two choices at each step to help identify organisms, while a branching key diagram visually presents the identification process through a branching structure where each branch leads to a different characteristic or group. Dichotomous keys rely on text-based descriptions, while branching key diagrams provide a visual representation of the identification process.
Why cells should remain small?
Not all calls are small. Slime molds for example have gigantic cells with tens of thousands of nuclei in each.
F you start with 5 cells how many cells will there be after two cell cycles of mitosis?
After one cell cycle of mitosis, the number of cells doubles to 10. After a second cell cycle, each of the 10 cells will divide again, resulting in a total of 20 cells. This is because mitosis involves one round of cell division followed by another round of cell division, leading to exponential growth.
How the shapes of various cells help each different type of cell to carry out its function within the body?
The shapes of various cells are closely linked to their specific functions in the body. For example, red blood cells are biconcave discs, which maximize surface area for oxygen transport and allow flexibility to navigate through narrow capillaries. Neurons have long, branching extensions called axons and dendrites that facilitate rapid communication across distances. Additionally, epithelial cells are often tightly packed and flat, allowing for efficient protection and absorption in tissues such as the skin and intestines.
Do all cells look alike in terms in shape and size?
No, cells can vary greatly in shape and size depending on their function and location in the body. For example, nerve cells can be long and thin, while red blood cells are small and round. Each type of cell is specialized for its specific role within the body.
How mnay chromosomes are in the cell after meiosis?
After meiosis, the resulting cells each have half the number of chromosomes as the original parent cell. In humans, for example, gametes (sperm and egg cells) have 23 chromosomes each, as opposed to the normal 46 found in somatic cells.
How many daughter cells result from one round of meiosis?
One round of meiosis results in four daughter cells. These daughter cells are genetically different from each other and the parent cell due to the process of crossing over and independent assortment during meiosis.
How many complete DNA molecules after three rounds of replication?
Each time a cell divides it's 23 PAIRS of chromosomes are divided and then 23 go to each of 2 new cells. Then each new cell with 23 chromosomes then replicates it's chromosomes so it has 23 PAIRs. Just look at a diagram of cell "mitosis". After the first mitosis: 46 pairs and 2 cells, Second round: 4 cells containing 92 PAIRS of DNA total. 3RD ROUND: Eights cells each containing 23 PAIRS of chromosomes: 8 x 23= 184 total chromosomes.
