Which statement best compares and contrasts lipids and carbohydrates?
HURRY PLEASEE I HAVE TWO MINUTES JUST THE LETTER AWNSER
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.

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?
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.

The molecule pictured below produced a blue color when tested with Benedict’s reagent, a yellow color when tested with IKI, and a violet color when tested with Biuret reagent. Based on the structure shown below and these chemical results, what kind of biomolecule is this? the molecule a blue color with benedicts reagent.no color change that given molecule is not a simple carbohydrate
Answer:
The molecule is a protein
Explanation:
When the molecule was tested with benedict's solution and a blue color was formed, that actually meant there was no colour change because the colour of benedict's solution is blue. Benedict's solution is used to test for the presence of reducing sugar, which changes it's colour to green, orange, yellow or even red; the fact that there was no colour change shows the molecule is not a reducing sugar.
Yellow colour when tested with IKI (Iodine-potassium iodide) also shows no colour change. IKI reagent is used to determine the presence of starch, which gives off a dark-blue colour if starch is present. Hence, absence of this dark-blue colour or observation of a yellow/orange colour shows the molecules is not starch.
Biuret reagent is used to test for peptide bonds in a molecule. In the presence of a peptide bond, the biuret reagent changes colour from blue to violet. The amino acids in proteins are held together by peptide bond, hence the biuret colour change shows that the biomolecule is a protein.

Which two organelles work together to create a functional protein.
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.

Explanation:
. Name the cells that are produced by the testes and ovaries.
Answer and explanation:
In the female of the species the reproductive cells are the egg cells, and in the male the reproductive cells are the sperm. The male gonad, the testicle, produces sperm in the form of spermatozoa. The female gonad, the ovary, produces egg cells. Both of these gametes are haploid cells. The testes contain germ cells that differentiate into mature spermatozoa, supporting cells called Sertoli cells, and testosterone-producing cells called Leydig (interstitial) cells.
