Which statement best compares and contrasts lipids and carbohydrates?

HURRY PLEASEE I HAVE TWO MINUTES JUST THE LETTER AWNSER

Answers

The correct answer is B. Both are used for energy storage, but only carbohydrates are used for short-term energy.

Explanation:

Carbohydrates and lipids are both biological macromolecules, which means they are essential for living organisms. Additionally, these are similar because they store energy. However, the type of energy they store is different.

Indeed, carbohydrates store short-term energy, which means carbohydrates are broken down a short time after ingested, and the energy in them is used. On the other hand, in lipids, the energy store is long-term energy, which means it is not consumed as fast as in carbohydrates. This occurs because lipids contain more energy. According to this, the correct statement is "Both are used for energy storage, but only carbohydrates are used for short-term energy".  

Answer:

B

Explanation:

Both are used for energy storage, but only carbohydrates are used for short-term energy storage.

what do you think the difference between simple and complex carbohydrates is?

Answers

Answer:

Complex carbohydrates are present in foods such as bread and pasta. Simple carbohydrates are in foods such as table sugar and syrups. Complex carbohydrates contain longer chains of sugar molecules than simple carbohydrates. The body converts these sugar molecules into glucose, which it uses for energy.

The independent variable in an experimental study is what the scientists can change in the experiment. The dependent variable is what the scientist measures in the experiment, or the outcome of the study. The controlled variables are all the features which are kept the same throughout the experimental study.

A farmer in Minnesota plants some tomato seeds in early spring. She plants them outdoors in soil and adds water every day. A few weeks later, nothing has happened. What is the most likely reason the seeds have not germinated?

Answers

Answer:

Other factors could affect the reason the seed didn't germinate because under suitable conditions depending on the variety it should germinate within 5 to 10 days from planting. However, the most likely reason it didn't germinate must be the Temperature.

Explanation:

From the question above, the farmer lives in Minnesota and she planted between March and May, meaning the temperature was way cold which is not suitable for tomato. One other valuable point was she planting outdoor which could also affect the performance of the tomato seedlings. Planting in early spring doesn't necessarily mean bad as some seeds might thrive under conditions explained above. For tomato, depending on temperature because too high temperatures could also affect the viability of the seeds. In Minnesota in early spring, it would have been better if she planted indoors to raise the temperature before transplanting as a balanced night temperature is also important for the seed viability.

Some other factors to be considered for seeds to germinate:

1. Water

2. Type of the soil

3. Seed depth in the soil

4. Nature of seed coat

5. Oxygen

6. Light

Eukaryotic cells are enclosed in the membrane, and the nucleus is bound by a nuclear membrane. Major parts of the eukaryotic animal cell are the nucleus, cytoplasm, mitochondria, Golgi, ER, etc.

What are animal cells?

Animal cells are eukaryotes that lack cell walls but have almost the same components as plant cells. The cytoplasm is the component of the cell where all the organelle lies.

The nucleus is the central organ that is involved in genetic replication and transcription and translation. Mitochondria are involved in the metabolic process and release of energy.

Golgi are involved in the packaging and transport of the proteins and ER produces proteins that are transported to the Golgi. Vacuoles though are present in small quantities they aid in the accumulation and elimination of the waste product.

Which statement about enzymes is true? A. An enzyme functions to decrease the rate of a chemical reaction. B. Enzymes are proteins that function as catalysts in nonliving things. C. Each enzyme can catalyze many different biochemical reactions. D. Enzymes and substrates fit together like a lock and key.

Answers

It would be answer D. because enzymes are a type of catalysts that function in living things and a substrate is a reactant that an enzyme catalyzes. An enzyme and substrate fit together perfectly like a lock and key as it catalyzes and produces a product

Enzymes are proteins that are like keys and fit into the lock called substrate to carry out the reactions. Thus, option D is accurate.

What are enzymes?

Enzymes are involved in metabolic reactions and act as catalysts by speeding up the reactions. They do not decrease the activity function of the rate of reactions in the living things.

A specific type of enzyme can catalyst only a single type of substrate and are unique for a reaction. Enzymes and substrates act as lock and key that fits together to carry out the reaction.

The active site of the enzymes is unique and fits into the substrate to form the complex resulting in a product formation.

Therefore, option d. enzyme and substrate are lock and key.

Which two organelles work together to create a functional protein.

Answers

Answer:

J

Explanation:

The two organelles that work together to create a functional protein are the ribosome and the endoplasmic reticulum (ER).

What if the function of ER and ribosome?

The ribosome is responsible for synthesizing the protein, while the endoplasmic reticulum provides the environment in which the protein can fold into its functional 3-dimensional structure.

In the cytoplasm, the ribosome reads the genetic information in messenger RNA (mRNA) and uses it to assemble a chain of amino acids, forming a protein. The ribosome then transfers the newly-formed protein to the endoplasmic reticulum.

The endoplasmic reticulum is a network of membranes that runs throughout the cytoplasm. It is involved in many cellular processes, including the folding and modification of newly-synthesized proteins. In the ER, the protein undergoes a series of post-translational modifications, such as the addition of carbohydrates, lipids, or phosphate groups. These modifications help the protein fold into its functional 3-dimensional structure and determine its final function in the cell.
