endoplasmic reticulum
Protein folding occurs in a cellular compartment called the endoplasmic reticulum. This is a vital cellular process because proteins must be correctly folded into specific, three-dimensional shapes in order to function correctly.
The organelle responsible for folding proteins in a cell is the endoplasmic reticulum (ER).
What is the endoplasmic reticulum and its functions?There are two types of ER: Smooth and rough ER. The rough endoplasmic reticulum (RER) is studded with ribosomes that synthesize new polypeptide chains. As the polypeptides are synthesized, they are translocated into the RER lumen, where they undergo folding and post-translational modifications, such as glycosylation and disulfide bond formation.
The RER is thus responsible for the quality control of proteins and ensuring that they are properly folded before they are transported to their final destination within or outside the cell.
Thus, the organelle responsible for folding proteins in a cell is the endoplasmic reticulum (ER).

Describe the Characteristics of a star
Answer:
A star shines a lot in the night, its color is saturated, the stellar mass, and size.
Explanation:
A star brightens up during the night due to their temperature (extremely hot). Its energy comes from natural nuclear reactions going into the star. The color of the stars come in any hex code, but usually the bluest one is higher temperature while the red one is lowest. The stellar mass describes the mass of a star and includes a formula to do. Stars also come in different sizes so there isn't a consistency when looking at them.

what is the density to the nearest hundredths, of a metal with a volume of 3.00 cm3 and a mass of 8.13g?
The density to the nearest hundredths, of a metal with a volume of 3.00 cm³ and a mass of 8.13g is 2.71g/cm³. Details about density can be found below.
How to calculate density?The density of a substance is a measure of the mass of matter contained by a unit volume and it can be calculated by dividing the mass of the substance by its volume.
According to this question, a metal with a volume of 3.00 cm³ and a mass of 8.13g is given. The density of the metal can be calculated as follows:
Density = 8.13g ÷ 3cm³
Density = 2.71g/cm³
Therefore, the density to the nearest hundredths, of a metal with a volume of 3.00 cm³ and a mass of 8.13g is 2.71g/cm³.

Inhibitors of microtubule synthesis inhibit mitosis by preventing the formation and function of which of these?
Answer:
Mitotic inhibitors are derived from natural substances such as plant alkaloids, and prevent cells from undergoing mitosis by disrupting microtubule polymerization, thus preventing cancerous growth. ... Mitotic inhibitors interfere with the assembly and disassembly of tubulin into microtubule polymers.
Mitotic inhibitors are the drugs which stop the mitosis where 1 cell gets divided into 2 , 2 to 4 and 4 to 8 in order to form identical cells. Inhibitors of microtubule synthesis inhibit mitosis by preventing the formation and function of microtubules.
What are microtubules made up of ?
Microtubules are made up of tubulin protein where they have the ability to show assembly and dissemble same as actin filaments.
Natural alkaloids are the inhibitors that prevent these mitotic spindle fibres to show any kind of assembly or dissembly in order to prevemnt multiple growth of the cells.
The multiple growth of cells will lead to condition called as tumor which is hazardous and abnormal cell growth condition.
The microtubules has a function of support, organisation of cytoplasm, chromosome segregation and many more.
These basically makes the skeletal structure of the cell and made up of tubulin alpha and beta structures.
Therefore, natural inhibitors alkaloids stops mitotic spindle fibres to stop showing any kind of assembly.

When people eat simple carbohydrates, they get _____.
A. energy very quickly
B. energy slowly, over a long period of time
C. information for how to build enzymes
D. material to build muscles
Answer:
In short The Correct Answer Is A. Energy Very Quickly, Which is the most common thing gotten from carbohydrates is energy although your body can also save the energy gained from carbohydrates for later the carbohydrates itself is processed very quickly compared to slowly...
Explanation:
Carbohydrates are a main source of energy for the body; they can be metabolized to ATP fast or slow depending on the body’s needs. Insulin brings glucose from the blood into the cells to be used for energy. The cell can either use it right away for energy or store it to use later.
Carbohydrates and Blood Sugar. When people eat a food containing carbohydrates, the digestive system breaks down the digestible ones into sugar, which enters the blood. As blood sugar levels rise, the pancreas produces insulin, a hormone that prompts cells to absorb blood sugar for energy or storage.
Some people can survive on few carbohydrates because the body can convert protein into carbohydrates to be used for energy. When people eat too many carbohydrates, often in the form of simple carbohydrates, they can gain weight because the body stores the extra carbohydrates as fat.

Explain what is most likely to be different about the poorly drained portion of the pasture in the following scenario.
Situation: A farmer has noticed that, while the majority of a pasture drains well without drying out and supports lush grass and leafy herbs, one portion is often poorly drained. The soil there is hard and compacted, and it is regularly invaded by a range of wild plants, including Russian Sage, asters, yarrow, and purple coneflowers. The farmer takes soil samples to discover what is different about this portion of his pasture.
Answer:
Soil texture.
Explanation:
The texture of soil is the main reason for its hardness and compact nature because texture of soil shows the characteristics of soil. There is high concentration or ratio of clay present in the soil which makes the soil hard and compact. Due to this texture, wild plants grow in this soil texture as well as poorly drained. So we can say that the texture of soil is responsible for its hardness.
