Hypothesis: If the amount of protein is calculated in three different lipid levels of milk, then whole milk will have the highest level of protein. What is the independent variable in this experiment? Type of protein Amount of protein Amount of milk Type of milk
Answer:
Type of milk
Explanation:
Independent variable is the variable that the experimenter changes or manipulates in an experiment. It is the variable that causes the dependent variable to change.
In this experiment, the hypothesis, which shows the relationship between the independent and dependent variable is stated as follows: IF the amount of protein is calculated in three different lipid levels of milk, THEN whole milk will have the highest level of protein. This shows that the amount of protein is dependent on the TYPE OF MILK used, which is the independent variable.
Imagine there was no tilt to the earths axis and earths orbit was circular
Answer:
If the Earth was not tilted on its axis, there would be no seasons. And humanity would suffer.
Explanation:
When a Mars-size object collided with Earth 4.5 billion years ago, it knocked off a chunk that would become the moon. It also tilted Earth sideways a bit, so that our planet now orbits the sun on a slant.

The diagram shows light- and dark-colored beetles that live on a tree.
Predator and Prey Relationship
Which result is most likely to occur to the beetle population due to predation over time?
Answer
F. The number of light-colored beetles in the population will increase
G There will be more dark-colored beetles than light-colored beetles
H The number of light-colored beetles will decrease
J
The dark-colored beetles will move to a different type of tree.
Answer:
F
Explanation:
I believe it F since there are far more light colored and the tree is a light color making them a bit camouflage but for black it will decrease since it's a different color from a tree making it easy to see
Based on the information provided, it is most likely that the number of light-colored beetles in the population will decrease over time due to predation, so the answer is option H
What is Predator and Prey Relationship?The light-colored beetles are more visible to predators, and therefore, are more likely to be eaten than the dark-colored beetles. As a result, over time, the proportion of dark-colored beetles in the population may increase, while the proportion of light-colored beetles decreases.
This type of natural selection, in which individuals with certain traits are more likely to survive and reproduce than others, is known as directional selection. It can result in changes to the characteristics of a population over time.

How does leaf structure allow for exchange of gases (O2 and CO2). Select 3 options.
Stomata (pores) let gases pass in and out.
Leaf is flat and thin = large surface area
The leaf has got Chloroplasts.
The Spongy Mesophyll layer has lots of space for gases to diffuse.
Answer:
Explanation:
Gas exchange
When a plant is carrying out photosynthesis carbon dioxide needs to move from the air into the leaf. It does this by diffusing through small pores called stomata. At the same time oxygen moves out of the leaf through the stomata. This movement of gases in opposite directions is called gas exchange.
