electrical energy
Explanation:
In physics, electromagnetic radiation (EMR) consists of waves of the electromagnetic (EM) field, propagating through space, carrying electromagnetic radiant energy. It includes radio waves, microwaves, infrared, (visible) light, ultraviolet, X-rays, and gamma rays.
The right answer is vein (it contains blood and has valves).
The infra-cardiac veins of small and medium caliber possess this system of fight against gravity. The valves consist of a dense connective tissue, surmounted by endothelial cells, corresponding to a fold of the intima. They allow blood circulation in the sense organ / heart but prevent venous reflux.
Answer:
Earth, both on land and in water. Wherever they
live, plants provide food and oxygen to the
creatures that live nearby – including humans!
In this activity we will examine both a
terrestrial (land) plant and an aquatic (water)
plant. They have many things in common, but the
ways they get air, food and water change along
with the environments in which they live.
Explanation:
Answer:
more exposure to sunlight and therefore increase photosynthetic production
Explanation:
Answer:
DNA is tightly packed up to fit in the nucleus of every cell. As shown in the animation, a DNA molecule wraps around histone proteins to form tight loops called nucleosomes. These nucleosomes coil and stack together to form fibers called chromatin. Chromatin, in turn, loops and folds with the help of additional proteins to form chromosomes. Condensing DNA into chromosomes prevents DNA tangling and damage during cell division.
