Which of the following is true regarding catabolic pathways? They consume energy to build up polymers from monomers. They lead to the synthesis of catabolic compounds. They release energy as they degrade polymers to monomers. They do not depend on enzymes.
Answers
Answer:
They release energy as they degrade polymers to monomers.
Explanation:
In a catabolic pathway, complex hydrocarbons are usually broken down to their monomeric units.
This breaking down leads to the release of energy.
Anabolic pathway leads to the build up of energy. One of such process is photosynthesis. The catabolic pathway breaks down compounds to simpler units in order to release energy.What is difference between acid and bases?
Definition. A substance, mostly liquid that donates a proton or accepts an electron pair in reactions. An acid increases the concentration of H+ ions. A base is a substance that releases hydroxide (OH-) ions in aqueous solution, donates electrons and accepts protons.

21. Choose one of the hypotheses from Question 20. Describe how you could set up an experiment to test the hypothesis by listing your experimental groups, control group, and at least 2 constants you would need to have.

A. If a player practices longer, then he will score more points in the game.
B. If students eat a high-protein breakfast, then they will score higher on their biology test.
Answers
Answer:
Biologists and other scientists use the scientific method to ask questions about the natural world. The scientific method begins with an observation, which leads the scientist to ask a question. She or he then comes up with a hypothesis, a testable explanation that addresses the question.
A hypothesis isn't necessarily right. Instead, it's a "best guess," and the scientist must test it to see if it's actually correct. Scientists test hypotheses by making predictions: if hypothesis \text XXstart text, X, end text is right, then \text YYstart text, Y, end text should be true. Then, they do experiments or make observations to see if the predictions are correct. If they are, the hypothesis is supported. If they aren't, it may be time for a new hypothesis.
How are hypotheses tested?
When possible, scientists test their hypotheses using controlled experiments. A controlled experiment is a scientific test done under controlled conditions, meaning that just one (or a few) factors are changed at a time, while all others are kept constant. We'll look closely at controlled experiments in the next section.
In some cases, there is no good way to test a hypothesis using a controlled experiment (for practical or ethical reasons). In that case, a scientist may test a hypothesis by making predictions about patterns that should be seen in nature if the hypothesis is correct. Then, she or he can collect data to see if the pattern is actually there.
Controlled experiments
What are the key ingredients of a controlled experiment? To illustrate, let's consider a simple (even silly) example.
Suppose I decide to grow bean sprouts in my kitchen, near the window. I put bean seeds in a pot with soil, set them on the windowsill, and wait for them to sprout. However, after several weeks, I have no sprouts. Why not? Well...it turns out I forgot to water the seeds. So, I hypothesize that they didn't sprout due to lack of water.
To test my hypothesis, I do a controlled experiment. In this experiment, I set up two identical pots. Both contain ten bean seeds planted in the same type of soil, and both are placed in the same window. In fact, there is only one thing that I do differently to the two pots:
One pot of seeds gets watered every afternoon.
The other pot of seeds doesn't get any water at all.
After a week, nine out of ten seeds in the watered pot have sprouted, while none of the seeds in the dry pot have sprouted. It looks like the "seeds need water" hypothesis is probably correct!
Let's see how this simple example illustrates the parts of a controlled experiment.

Transpiration (the evaporation of water out of the leaves) helps
pull what up through the roots and stems and into the leaves?
Answers
Transpiration helps to pull water and dissolved minerals up through the roots and stems of plants and into the leaves, which is present in the third option as the transpiration creates a negative pressure, or tension, in the leaf tissues.
What is transpiration?
Plants absorb water and minerals from the soil, and these minerals, such as nitrogen, phosphorus, and potassium, are essential for plant growth and development, the roots of plants have tiny, hair-like structures called root hairs, which increase the surface area of the root and help in the absorption of water. Water and minerals are absorbed by the roots to be transported upwards through the plant stem to the leaves, and this transport occurs in specialized vascular tissues called the xylem and the phloem.
Hence, transpiration helps to pull water and dissolved minerals up through the roots and stems of plants and into the leaves, which is present in the third option.

Several parts of an animal cell are involved in the processes of protein synthesis, packaging, and export.
Answers
Full question:
Several parts of an animal cell are involved in the processes of protein synthesis, packaging, and export. Which of the following correctly places the cell parts in the order in which they are involved?
nucleus → vacuole → cell membrane mitochondria → vacuole → cell membrane ribosome → endoplasmic reticulum → Golgi complex → cell membrane lysosome → endoplasmic reticulum → Golgi complex → cell membraneAnswer:
ribosome → endoplasmic reticulum → Golgi complex → cell membrane
Explanation
First, the DNA is transcribed into mRNA in the nucleus. The mRNA then moves to the cytoplasm. Here, it encounters the ribosomes.
At the ribosomes. the mRNA is translated into protein. It gets folded in the endoplasmic reticulum and then is transferred to the Golgi complex.
At the Golgi complex, proteins are modified, packaged, and transported to their destination in a series of vesicles, which if it is outside the cell, is the cell membrane.

THYLAKOID
ADP

NADP
2. What is the NADPH responsible for?
3. Where do the "light" reactions (light-dependent) take place?
Answers
Answer:
A) Light dependent reactions
Reactants: light, H2O
Products: Oxygen gas
B) Light independent reactions
Reactants: C02
Products: Glucose
2. NADPH is an electron carrier which transfers electrons in the electron transport chain of photosynthesis
3. Light reactions occur in the THYLAKOID membrane.
Explanation:
As depicted in the image in this question, the photosynthetic process can be grouped into two stages viz; light dependent reactions and light independent reactions. The light dependent reactions, which take place in the THYLAKOID MEMBRANE of the Chloroplast, involves the synthesis of ATP (energy carrier) and NADPH (electron carrier) to be used in the next stage. The reactants of light dependent reactions are light energy from sun, and water (H2O) while the product is Oxygen (O2) gas.
In the light independent reactions, the ATP and NADPH are used to synthesize GLUCOSE as a product from Carbon dioxide (CO2) reactant.
2. The NADPH is is an electron carrier produced from the reduction of NADP+, which transfers or donates electrons to other molecules in the electron transport chain of photosynthesis. This is crucial in building of the proton gradient for ATP production.
3. The light reaction or light dependent reaction takes place in the THYLAKOID MEMBRANE of the Chloroplast.
The light-dependent reactions use ADP and NADP to produce NADPH and ATP (it occurs in the thylakoid membrane), whereas light-independent reactions use NADPH and ATP. NADPH is a cofactor.
The light-dependent reactions use sunlight and water (H2O) to produce oxygen (O2), NADPH and ATP, whereas light-independent reactions use carbon dioxide (CO2) NADPH, and ATP to produce simple carbohydrates (e.g., glucose).Both light-dependent reactions and light-independent reactions occur in the chloroplast: light-dependent reactions occur in the thylakoid membrane of the chloroplast, whereas light-independent reactions occur in the stroma of the chloroplast.Reduced nicotinamide adenine dinucleotide phosphate (NADPH) is a cofactor that transports electrons (e-) and protons (H+) released by sunlight into new carbon-carbon bonds and thus serves to produce simple carbohydrates (i.e., sugars).In conclusion, the light-dependent reactions use ADP and NADP to produce NADPH and ATP (it occurs in the thylakoid membrane), whereas light-independent reactions use NADPH and ATP to create carbohydrates.
