Answer:
d) B and C are both true
Explanation:
Prokaryotic cells: The term "prokaryotic cells" are described as cells that don't consist of "membrane-bound organelles" or "true nucleus". However, the organisms that come under the domain of Archaea and bacteria tend to possess prokaryotic cells and it has been described that organisms that consist of prokaryotic cells are abundant in nature and make most of the Earth Biomass. Prokaryotic cells don't possess the nucleus rather have one chromosome.
In the question above, the correct answer is option D.
Answer: 100mL sucrose solution and 900mL water
Explanation: sucrose solution is 500 mM, i.e. 500mmol/L
water is 0mmol/L
To get 50mmol/L we need 1/10 L of sucrose solution = 100mL
and made up to 1L with water
Answer:Spectroscopy helps astronomers to determine the composition, temperature, density, and motion of an object.
Infrared spectroscopy helps to identify the atoms and molecules in the object.
The red shift or blue shift (Doppler Effect) in a spectral line tells how fast the object is receding from Earth or coming toward it.
The Doppler shift enables astronomers to discover extrasolar planets.
As a planet orbits its star, the star is alternately moving away from or toward us.
Astronomers can use the Doppler shifts to calculate the speed of the star and the mass of the planet that is tugging on it.
Explanation:
Plantlike and methanogen organisms share som similar characteristics, for instance, can both produce their own and can process their made food into energy for different cellular processes such as cell division, repair and maintenance.
Despite this similarity though, the difference lies with the source of energy that get to produce the food. Plantlike organisms use sunlight and UV rays to photosynthesize. Whereas, methanogens use methane where sunlight is not present.
