Microscopy is not a method used to detect extrasolar planets.
<h3>Methods of detecting exoplanets:</h3>
Any planetary body beyond the solar system that typically orbits a star other than the Sun is referred to as an extrasolar planet, often known as an exoplanet. There are 3,779 planetary systems with 3,108 confirmed exoplanets as of 1 July 2022, 826 of which contain multiple planets. The Kepler space telescope was responsible for most of these discoveries.
Exoplanets contain elements that are comparable to those found in our solar system, but their compositions of those elements may vary. Iron or carbon may dominate some planets, whilst water or ice may rule others.
The following methods have at least once proved successful for discovering an extrasolar planet or detecting an already discovered planet:
- Radial velocity
- Transit photometry
- Ellipsoidal variations
- Pulsar timing
- Variable star timing
- Transit timing
- Transit duration variation
- Eclipsing binary minima timing
- Gravitational microlensing
- Direct imaging

Answer:
a. the process by which new blood vessels develop
c. undelies much of the growth and spread of different cancers
d. controlled by vascular endothelial growth factor (VEGF)
e. occurs with endurance training
Explanation:
Angiogenesis is the process of forming new blood vessels in the human body. The new blood vessels formed by growth, migration and differentiation of the endothelial cells located in the wall of blood cells. The formation of new blood cells (angiogenesis) is under control of vascular endothelial growth factor (VEGF). The new blood vessels provides oxygen and nutrients to the growing tumors, angiogenesis helps in growth and spread of cancer.
The EPA is an independent agency formed for environmental protection. Hence the statement The Clean Air Act would be a reason for the Environmental Protection Agency (EPA) to regulate car emissions is true.
Car emissions are very harmful for all the living organisms in an environment.
C. Calcium Salts

Answer: option A - tumor-suppressor gene
Explanation:
A cancerous tissue is growing or spreading rapidly at a harmful rate. However, for a tissue to become cancerous, its "internal guard" usually known as a TUMOUR SUPPRESSOR GENE must have lost or reduced its function.
This loss of function occurs after mutation.
So, definitely, all affected individuals with cancerous tissues have mutated tumour suppressor genes unlike unaffected individuals.
Note that other options are WRONG, because none of them accurately distinguishes affected from unaffected individuals
