Answer:
To store genetic information to pass on to other living organisms.
A star’s life expectancy depends on its mass. Generally, the more massive the star, the faster it burns up its fuel supply, and the shorter its life. The most massive stars can burn out and explode in a supernova after only a few million years of fusion. A star with a mass like the Sun, on the other hand, can continue fusing hydrogen for about 10 billion years. And if the star is very small, with a mass only a tenth that of the Sun, it can keep fusing hydrogen for up to a trillion years, longer than the current age of the universe.
Answer:
The correct answer will be option - D.
Explanation:
Slime moulds are the fungus-like protists which bear a structure called sporangium which produces spores. The sporangium is produced in fungi as well due to which these protists are called fungus-like. Although both produce sporangium but they are not closely related, rather they are distantly related organisms.
The appearance of a sporangium in both indicates that they had faced the same conditions due to which they both showed the same adaptation by producing the same structures performing the same function. In evolutionary terms, this is an example of convergent evolution.
Thus, option D is the correct answer.
Answer:
(B) open stomata only at night, limiting water loss because of heat and low humidity.
Explanation:
CAM plants are found in the regions characterized by very hot and dry environmental conditions. These plants reduce the water loss through transpiration by exhibiting CAM photosynthesis.
They open the stomata during night time when the air is cooler and rich in moisture. They take in CO2 during night time and fix it into the oxaloacetate which in turn is converted into malate and is stored in the vacuoles.
During day time, stomata remain closed to prevent water loss and the CO2 trapped during night time (released by decarboxylation of malate) enter the Calvin cycle.
Answer:
The earth-sun-moon system affects a lot of things on earth, some of which are agriculture, tides, seasons, temperature, weather/climate, living things, ect.
