Food is the answer it’s that simple appreciate this sn I really don’t know I’m sorry ...
Based on the description of events, being that the lizard population appears to increase as soon as the snake population decreases, it appears that the snakes prey on the lizards. This suggests that the snake is a keystone species. A keystone species is one that has a dramatic effect on maintaining the balance of an ecosystem. As soon as the snake population decreases, major changes occur to the ecosystem, such as the lizard population increasing.
Therefore, the answer is D: <span>The snake is a keystone species in the ecosystem.</span>
1) False. Scientists may predict something but realize a difference soon after before the test, so they could definitely change the hypothesis if they want. It’s only AFTER the experiment they cannot. Because a hypothesis is like a “guess” as to what’s going to happen, right?
2) False. A hypothesis can’t be “valid” because it’s literally a prediction.
3) True. Especially if you’re doing a chemistry lab, it’s really important things are done in order or else the product might result as something else you were expecting, or can be very dANGEROUS
4) True. The conclusion must be based on data because it’s the observation that was seen.
Hope this helps!! I could have answered in short form but I just wanted to make them understandable:)
Low-density lipoproteins (LDL) are the principal transport vehicle for cholesterol in the blood.
The body needs cholesterol, a waxy, fatty molecule, in the proper proportions for overall health. High blood cholesterol is a disorder that can result from unfavorable cholesterol levels. Low-density lipoprotein (LDL), also known as "bad" cholesterol, is the type of lipoprotein that carries cholesterol in your blood.
Cholesterol is primarily brought on by consuming fatty foods, failing to exercise regularly, being overweight, smoking, and using alcohol. Moreover, it can run in families. By consuming a healthy diet and increasing your physical activity, you can lower your cholesterol. Some folks also require medication. The majority of the cholesterol in your body is LDL (low-density lipoprotein), also referred to as "bad" cholesterol. Your risk of heart disease and stroke increases if your LDL cholesterol levels are high.
