What else can I help you with?
What is the area where chromosomes are normally found in a cell that ends with a s?
The area where chromosomes are normally found in a cell that ends with an "s" is the nucleus.
Does calcium depolarize or hyperpolarize cell membranes?
Calcium depolarizes cell membranes.
Structure in an animal cell that aids in cell division(normally in pairs?
Centrioles are the structures in animal cells that aid in cell division and are normally found in pairs at the centrosome. During cell division, the centrioles help organize the microtubules of the spindle apparatus, which is crucial for proper chromosome segregation.
During cell reproduction the chromosomes condense from the that is normally found in the nucleus?
During cell reproduction, chromosomes condense from the chromatin that is normally found in the nucleus. Condensation helps the chromosomes become more manageable and facilitates their movement during processes such as mitosis and meiosis. After cell division is complete, the condensed chromosomes will decondense back into chromatin.
A Barr body is normally found in the nucleus of which kind of human cell?
A Barr body is normally found in the nucleus of female human cells. It is an inactivated X chromosome, which compensates for the presence of two X chromosomes in females by silencing one of them to achieve dosage compensation.
Where in a heart cell is calcium normally stored?
Outside the cardiac muscle cell
Where in a heart cell is potassium normally found?
Potassium is found in the cardiac cells as well as the extracellular fluid surrounding the heart.
What is the area where chromosomes are normally found in a cell that ends with a s?
The area where chromosomes are normally found in a cell that ends with an "s" is the nucleus.
Calcium is found in which part of the body?
Calcium is stored in bones, with a smaller amount in the blood, and in each cell.
What organelle is not normally found in the plant cell?
Centrioles are organelles not normally found in plant cells. They are involved in cell division and are typically found in animal cells, where they play a role in organizing the mitotic spindle during cell division.
What structure would normally be found in a plant cell but not in a animal cell?
Plants have a CELL WALL where animals do not.
What is the purpose of the sodium-calcium exchanger in cardiac muscle?
Unlike skeletal muscles, cardiac muscles need extracellular calcium ions in order to perform contractions. The sodium-calcium exchanger is the protein that facilitates this transfer, trading calcium from outside the cardiac cell with sodium inside the cell.
How do calcium channel blocking agents work?
Inhibit the movement of ionic calcium across the cell membrane. This reduces the force of contraction of heart muscles and arteries.
During contraction of the heart muscle cells?
some calcium enters the cell from the extracellular space and triggers the release of larger amounts of calcium from intracellular stores
What effect does calcium have on the heart rate?
The resting membrane potential is maintained by the distribution of positive and negative charged ions across both sides of the cell membrane. At rest, calcium concentration in cells of the heart is low as compared to the outside. At action, calcium channels in the membranes open, thereby allowing calcium to rush into the cells. So raising the heart rate.
What is normally found in the vacuole of a cell?
vacuoles are filled with water cell sap which contains food,cell secretions,and wastes
What structures normally found in animal cells not in plant cells?
cell wall
