You are given four test tubes containing purified biological macromolecules. The test tubes are unlabeled except for a number be

tween 1 and 4. You are told that one test tube contains a protein, one contains a lipid, one contains a carbohydrate, and one contains a nucleic acid. You then perform some tests on the macromolecules and collect the following information:
A. Test tubes 2 and 4 contain nitrogen, but the other tubes do not.
B. The contents of test tube 3 are not soluble in water, but the contents of the other test tubes are soluble in water.
C. The contents of test tube 1 can be broken down into subunits that are all exactly identical to each other.
D. The macromolecule in test tube 2 is found to have a globular shape. What are the identities of the macromolecules present in the four test tubes?

Answer:

Test tube 1 carbohydrates

Test tube 2 protein

Test tube 3 lipids

Test tube 4 nucleic aci

Explanation:

nitrogen can be found in both

Test tubes 2 and 4 indicating possibilities of proteins and nuciec acids

Test tube 3 should contain lipids due to its non-water solubility properties.

carbohydrates (made out of sugar units) should be the constituents of test tube 3 considering other test tube analysis

Globular shape can be seen in test tube 2, then it will be protein when considered with molecular level due to linear structure of DNA

Can individual nucleic acid have globular shape or not. The answer is no

Our conclusion;

Test tube 1 carbohydrates

Test tube 2 protein

Test tube 3 lipids

Test tube 4 nucleic acid

Which of the following statements is true of imagined risks?
bija089 [108]
Let's go through the choices!

A. They're unaffected by positive self-talk.

Let's pretend you are scared of thunder. If you tell yourself, "I will not let thunder scare me; it will not hurt me," you will be less scared! So, A is not the answer.

B. They're harmless, because they're imaginary.

If you are scared of something, it can damage your mental health, which is not harmless. So, B is not the answer.

C. They're a kind of negative self-talk.

Being afraid of something is usually due to an overexaggeration in your mind. So, C is a good answer.

D. They're a kind of positive reinforcement.

Being scared is not positive. So, D is not the answer.

The answer is C!

Hope I helped! :)

What is the complex and non-linear process of energy flow between species known as? The complex and non-linear process of energy
Natalka [10]

Answer:Ecosystem Energy  

Nearly all of the energy that drives ecosystems ultimately comes from the sun. Solar energy, which is an abiotic factor, by the way, enters the ecosystem through the process of photosynthesis

The energy input, or energy that enters the ecosystem, is measured in Joules or calories. Accordingly, the energy flow is also called calorific flow.

The macro-nutrients needed by plants are nitrogen, phosphorous, and potassium. What is the function of each of these elements?
bezimeni [28]

Answer:

The primary macronutrients are Nitrogen (N), Phosphorus (P), and Potassium (K). Nitrogen is essential for plant development, since it plays a fundamental role in energy metabolism and protein synthesis. Nitrogen is absorbed by the plant in the form of a nitrate. This macronutrient is directly related to plant growth
