Answer:
r= 0
Step-by-step explanation:
Cancel equal terms on both sides of the equation:
= 3r - 5r = -4r
collect like terms
= -2r = -4r
move variable to left and change its sign
= -2r + 4r = 0
collect like terms
= 2r = 0
divide both sides of the equation by 2
r=0
-11 1/3 = -34/3
Because 3(-11) = -33 -1 = -34/3
Answer:
Step-by-step explanation: The brains are very similar insofar that they function in almost the same way when it comes to controlling physical aspects of our existence. Our brains regulate our organs and our body parts just like a sheep's brain.
Answer:
Food web
Step-by-step explanation:
Food chain describes how each living organism feed.
Plants are producers because the use photosynthesis to grow and provide nutrients which animals later come to consume, because animals devour plants or animals because they cannot produce their own food like plants. The animals are known as consumers.
Fungi is also a consumer because it absorbs the nutrients available from other living organisms.
Consumers are classified into three types:
1. Carnivores are organisms that feed mainly on animals
2. Herbivores who feed on plants
3. Omnivores who feed on both plants and animals.
A food web describes the relationship between various food chains and how they interact with each other in the eco system.
