Answer
c
Explanation:
because mechanical energy has approximately 2.65% chemical energy causing it to be able to constantly change.
Answer:
The correct answer will be- formation of membrane
Explanation:
The three-stage origin of life theory suggests that life on Earth originated in three phases which are:
1. Phase I: The larger molecules formation began during this unsuitable earthly conditions full of volcanic eruptions and harmful gases underwater.
2. Phase II: The self-replicating molecule begins to form during this phase which contained the coding of life. The self-replicating molecule is known as the formation of the membrane.
3.Phase III: The formation of the membrane which help separate the outer environment from the inner environment was observed during this phase.
Thus, the formation of a membrane is the correct answer.
Answer:
A band - light central region of sarcomere.
Explanation:
Sarcomere is the basic structural unit of the skeletal muscles. These sarcomere shows striations ( light and dark bands) when veiw under the microscope.
A band or anisotropic band is the dark region of sarcomere. A band consists of both thick and thin filaments of actin and myosin proteins. The A band has the ability to refract light and appears dark.
Thus, the correct answer is option (D).
Children of CF carriers can inherit their copy of the CFTR gene mutation. There is a 25% (1 in 4) probability that a child born to two CF carriers will have the disease.
<h3>What causes cystic fibrosis primarily?</h3>
- Cystic fibrosis is brought on by a mutation in the CFTR gene (cystic fibrosis transmembrane conductance regulator).
- This gene regulates the movement of fluids and salt into and out of your cells.
- When the CFTR gene isn't functioning properly, your body produces a buildup of sticky mucus.
<h3>Cystic fibrosis usually results in death.</h3>
- When cystic fibrosis causes a severe illness or the lungs stop functioning properly, it can be fatal.
- It also has a tendency to get worse over time. However, because to improvements in medicine, patients with cystic fibrosis are now living longer.
- Approximately half of those who have cystic fibrosis will live past the age of 40 at this time.
