Answer:
See explanation below:
Explanation:
Transit Photometry is the most widely-used and effective to date, it has been a method that measures the light curve of distant stars for periodic dips in brightness. These are the result of exoplanets passing or transiting in front of the star relative to the observer. It is currently the most effective and sensitive method for detecting extrasolar planets, particularly from an observatory in space. When combined with radial velocity data, a transit can also provide a good estimate of the planet's mass. This method detects distant planets by measuring the minute dimming of a star as an orbiting planet passes between it and the Earth.
The main reason direct detection of exoplanets is difficult is because most planets orbit planets orbit at small angular separations on the sky, this means a direct detection is only possible if the star's light can be suppressed or occulted such that the faint light from the planet can be detected.
Some planets are found via the wobble method, using both methods, combining mass and size, scientists can calculate the planet's density, an important step towards assessing its composition.
Answer: True
Explanation: There are some microorganism tend to spoil the food and produce the bad odor, spoilage etc in the food which may lead to disease like food borne disease.This disease leads to the serious health conditions or sometimes death.Example of such bacteria are-Serratia, Lactobacillus etc. These microbial organism infect the food and thus lead to food borne disease . So,the statement given is true.
In the following statements, a challenge that the agricultural faces in the coming decade would be B. Farmers in Africa must adopt new methods in order to meet their needs. The IAASTD would respond to the widespread realization about the technological achievements.
I think it’s Mongolia and China. Again I’m not sure so I’m sorry if I got it wrong.
