Answer is: <span>Mutations sometimes improve the chances of survival for a plant.
</span>Mutations are very important because they change <span>variability in populations and in that way enable evolutionary change.
</span>There are three types of mutations:
1) good or advantageous mutations - <span> improve the chances of survival for a plant.
2) </span>bad or deleterious - decrease the chances of survival for a plant.
3) neutral - not affect he chances of survival for a plant.
Answer:
Biodiversity can be seen within species, between species, and within and between ecosystems. Although biodiversity is hard to measure on a global scale, in recent years there has been scientific consensus that the planet’s biodiversity is in decline. That’s not great news, because in general, the more species that live in an area, the healthier that ecosystem is—and the better off we humans are.
Explanation:
Plants and animals RE a carbon source during respiration. they take in Oxygen and give out Carbon (IV) oxide as a by product. Combustion of fossil fuels is also source of carbon (IV) Oxide.
Formation of fossils from dead plants and animals is a carbon sink. photosynthesis is also a carbon sink as plants take in carbon (IV) Oxide that is used to make food.
Answer:
The temperature at which the glass vessel shatter is = 341.33°c
Explanation:
Initial temperature = 18 °c = 291 K
Initial Pressure = 0.9 atm
Final pressure = 1.9 atm
From ideal gas equation
P V = m R T
Here volume & mass & gas constant is constant so Pressure is directly proportional to the temperature.
= 613.33 K = 341.33°c
Therefore the temperature at which the glass vessel shatter is = 341.33°c
