Answer:
Explanation:
Mechanical advantage is given by the ratio of output force by input force.
= Output force = 
= Input force = 
So,
The mechanical advantage of the pulley's is .
From the insects and the worms they eat.
Answer:
B. Are the insect’s antennae longer than its head?
Explanation:
Dichotomous key refers to the tool or method which helps the scientist to identify organisms.
It uses a specific series of questions which help in segregation of organisms and ultimately help the scientist to identify the organism on the basis of the observations or properties share by the organism.
Example of a simple dichotomous key is shown below.
Similarly, insects can have antennae longer or shorter than their heads. Thus, the question "Are the insect’s antennae longer than its head?" would help in segregating insects based on their antennae length.
happy to help ya:)
Hey there, thx for posting your question to Brainly, i've posted some information below and an explanation, hope it helps you<3
Carbon moves from the atmosphere to plants. In the atmosphere, <em>carbon is attached to oxygen in a gas called carbon dioxide (CO2)</em>. Through the process of <u>photosynthesis, carbon dioxide is pulled from the air to produce food made from carbon for plant growth.</u>
<u>Carbon moves from plants to animals. Through food chains, the carbon that is in plants moves to the animals that eat them. Animals that eat other animals get the carbon from their food too.</u>
<u>Carbon moves from plants and animals to soils. When plants and animals die, their bodies, wood and leaves decays bringing the carbon into the ground. Some is buried and will become fossil fuels in millions and millions of years.</u>
