Answer:
The correct option is E) Contraction still occurs because Ca2+ can enter the cell directly through Ca2+ channels in the plasma membrane and bind to calmodulin.
Usually, the calcium ions are released from the sarcoplasmic reticulum of a cell during a muscle contraction, but if those are blocked, the contractions is an cell can still arise through the calcium ions which are present in the cell membrane of a cell.
Answer: Because The potential energy you build going up the hill can be released as kinetic energy — the energy of motion that takes you down the hill. Once you start cruising down that first hill, gravity takes over and all the built-up potential energy changes to kinetic energy. Gravity applies a constant downward force on the cars.Potential energy is the energy an object has as a result of its position. Potential energy is stored energy that has not yet been released. Gravitational potential energy is potential energy that results from an object's position in a gravitational field, and is equal to the object's weight multiplied by its height.
hope this helps have a nice day❤️
Explanation:
With the sequence of the gene-coding regions of the human genome in hand and the development of newer sequencing methods, scientists are able to
1. develop new forensic tests that can help in the identification of the convict.
2. diagnose genetic diseases before their onset.
3. develop customised medicines based on the genetic profile of the patient.
4. therapeutically target the cancer causing genes (oncogenes) in the patients.
5. understand the inheritance of genes especially the rare mutations in a population.
A scientist developing vaccines for diseases would have taken many specialized classes in immunology.
