Usually is only because of blood vessels breaking in the skin.
Answer:
<u>Option- D: </u>Is the best choice to choose from the given options.
Now, let us explain the term Cell cycle in a more comprehensive way.
<u>As the cell cycle is controlled at three checkpoints.</u>
- The integrity of the DNA is assessed at the G₁ checkpoint.
- Proper chromosome duplication is assessed at the G₂ checkpoint.
- Attachment of each kinetochore to a spindle fiber is assessed at the M checkpoint.
Explanation:
The cell cycle is controlled by three internal checkpoints that evaluate the condition of the genetic information.
- <u>The G₁ Checkpoint</u>:This stage determines whether all conditions are favorable for cell division to proceed. The cell can halt the cycle and attempt to remedy the problematic condition, or the cell can advance into G₀ (inactive) phase and await further signals when conditions improve.
- <u>The G₂ Checkpoint:</u> The most important role of the G₂ checkpoint is to ensure that all of the chromosomes have been accurately replicated without mistakes or damage.
- <u>The M Checkpoint:</u>It occurs near the end of the meta-phase stage of mitosis. it determines whether all the sister chromatids are correctly attached to the spindle micro-tubules
Respiration is a chemical reaction that takes place in cells and allows them to release energy. Reactants are the substances that react together in a chemical reaction. In respiration the reactants are glucose and oxygen.
The food that we eat give us the energy that we have in our bodies. That energy can help us in out everyday lives .
Answer:
First of all is ventral: cavity that makes up the thoracic and abdominopelvic cavity ventral: cavity that makes up the thoracic and abdominopelvic cavity
Secondly it is thoracic: chest cavity
And thirdly it is pleural cavities: which consist of ths lung cavity
That is it will encounter tbe parietal layer of the serous membrane first :lines cavity
Explanation:
The organs in the body are safely guarded by the membrane, cavities and sheaths(which has different compartment). They act to protect the organs in the body like lungs.
A person who was shot with a gun, the bullet must pass the body cavities when moving to the lungs. It must first pass through the 3 cavities before it arrives at the lungs that is the ventral cavity, thoracic cavity and the pleural cavity. The serous membrane is usually found within the walls of the thoracic cavity.
