The meteorite was probably 1<span>0 to 15 km (6.2 to 9.3 mi) wide</span> and affected the entire planet through a proces called "impact winter". As the name suggests, an impact winter is a period of low temperature produced by a huge cloud of ash and dust that blocks sunlight. Since sunlight is essential for plants to survive, if the sun rays are blocked by this cloud, all animals that depend on those plants (including dinosaurs) will die. The meteorite could have created such a cloud upon hitting the earth.
Answer:
external
Explanation:
<em>Through the process of photosynthesis, plants use the sun's energy to make sugars to function. External means from an outside force, while internal means from within. Since the sun isn't inside a plant, they gather it from outside, thus it's external.</em>
D. Brain activity doesn't necessarily cause behaviour just because they coincide.
Explanation:
- Neuroscience is the study of the neurons. This deals with how the nervous system develops, the structure of the nervous system and its actions.
- Neuroscientists are focusing on the brain and its impact on cognitive functions and behaviour.
- Scientists proved that the chemicals present in the brain are responsible for our general state and mood that we are going through. Damage of brain cell will affect our impulses and the impulsive behaviours.
Hey,
I believe this answer is A: The desert plants are likely to be better at retaining water.
Which they do, and they have to cause water is very scarce in the desert unlike the rain forest.
Desert plants likely to be larger is not proven and most plants can vary in size.
Narrower stems may have something to do with it but that goes back to they have to hold more water so this is incorrect.
Brighter flowers doesn't have anything to do with water consumption within a plant so this is incorrect as well.
Hope this helps!
Brainliest is always appreciated if you feel its deserved.
