<span>Sugar dissolves in water because both substances are polar substances. Water dissolves the majority of substances that are polar or ionic. The fact that sugar dissolves in water is unusual because most molecular compounds are nonpolar and are not water-soluble.  

Or Number 2.</span>Sugar is a molecular compound, which means it is comprised of covalent bonds by which the atoms in the molecule share their valence electrons. This is the opposite of ionic bonding, in which atoms donate or receive electrons and change their attractive charges individually. The type of bonding atoms undergo when they react together depends on the difference in their electronegativity values. If the difference is great, they exhibit ionic bonding. If there is no difference or only a slight difference, they form covalent bonds, with the covalent bonds becoming more polar as the difference becomes greater.

In a polar covalent bond, the electrons are shared unevenly. This creates a slightly negatively charged end and a slightly positively charged end in a phenomenon known as a dipole shift. These ends allow for intermolecular interactions and give water its properties as a solvent. Polar bonds contribute to the overall polarity of the molecule, although it should be noted that not all molecules with polar bonds are completely polar. hope that helped

Starting with a protein that has been inserted into the Endoplasmic reticulum (ER) membrane with the Amino (N) terminal in the E
Vika [28.1K]

Answer and Explanation:

Ribosomes are the primary structure for protein synthesis. They can be found in the rough endoplasmic reticulum or floating in the cytosol.  

Free ribosomes are not attached to any cytoplasmic structure or organelle. They synthesize proteins only for internal cell use. Other ribosomes are attached to the membrane of the endoplasmic reticulum and they are in charge of synthesizing membrane proteins or exportation proteins. Free and attached ribosomes are identical and they can alternate their location. This means that although free ribosomes are floating in the cytosol, eventually, they can get attached to the endoplasmic reticulum membrane.  

Synthesis of proteins that are destined to membrane or exportation starts in the cytoplasm with the production of a molecule portion known as a <u>signal aminoacidic sequence</u>. This signal sequence varies between 13 and 36 amino acids, is located in the <u>amino extreme</u> of the synthesizing protein, and when it reaches a certain length, it meets the <u>signal recognizing particle</u>. This particle joins the signal sequence of the protein and leads the synthesizing protein and associated ribosome to a specific region in the Rough endoplasmic reticulum where it continues the protein building. When they reach the membrane of the endoplasmic reticulum, the signal recognizing particle links to a receptor associated with a pore. Meanwhile, the ribosome keeps synthesizing the protein, and the enlarged polypeptidic chain goes forward the reticulum lumen through the pore. While this is happening, another enzyme cuts the signal sequence, an action that requires energy from the ATP hydrolysis. When the new protein synthesis is complete, the polypeptide is released into the reticulum lumen. Here it also happens the protein folding (which is possible by the formation of disulfide bridges of proteins are formed) and the initial stages of glycosylation (the oligosaccharide addition).  

Once membrane proteins are folded in the interior of the endoplasmic reticulum, they are packaged into vesicles and sent to the Golgi complex, where it occurs the final association of carbohydrates with proteins. The Golgi complex sends proteins to their different destinies. Proteins destined to a certain place are packaged all together in the same vesicle and sent to the target organelle. In the case of membrane proteins, they are packaged in vesicles and sent to the cell membrane where they get incrusted.  

There are certain signal sequences in the <u>carboxy-terminal extreme</u> of the protein that plays an important role during the transport of membrane proteins. A signal as simple as one amino acid in the c-terminal extreme is responsible for the correct transport of the molecule through the whole traject until it reaches the membrane.

(IMPORTANT IN NEED OF HELP!!)
bija089 [108]

Clean or green energy helps in releasing lesser air pollution and lesser carbon dioxide. That contributes in lowing down global warming and subsequent disasters like tsunami because of glacier melting , more unexpected climate changes like unexpected long-period storms, flood, typhoons,  etc.

Hope this would help.

Which statement about positive feedback regulation is accurate?
GenaCL600 [577]

Answer:

Answer is B. Positive feedback regulation can generate an abrupt, all-or-none response in which the cell moves from ignoring a signal to responding to it very strongly.

Explanation:

Positive feedback can be described as an example of feedback, which is a natural mechanism that amplifies the action of a system.

It can be better be explained further, as a situation whereby the blood pressure decreases and the response of the body also makes or causes the blood pressure to decrease the more.

Other examples of a positive feedback also include blood clotting, ripening of fruits , uterus muscle contraction, resulting to the stretching of the uterus during pregnancy.
