Answer: the residues are connected differently in starch and cellulose.

Explanation:

Starch is formed from alpha glucose, while cellulose is made of beta glucose. The difference in the linkages lends to differences in 3-D structure and function. Starch can be straight or branched and is used as energy storage for plants because it can form compact structures and is easily broken down.

Some proteins on the surface of a mammalian cell contain carbohydrates. These proteins are synthesized by _______ and the sugars
sleet_krkn [62]

Answer:

c) Ribosomes on the rough endoplasmic reticulum; Golgi apparatus

Explanation:

Endoplasmic reticulum, a member of endomembrane system. If it contains ribosomes on their surface, they are called Rough Endoplasmic Reticulum (RER). RER is the site for protein synthesis.

Newly formed protein undergoes modification, one such modification is the addition of carbohydrate side chains to form glycoprotein. The protein then moves to the Golgi for modification.

A rat deprived of food will learn a new response even if it is given only a nonnutritive, saccharine-sweetened substance after p
sergiy2304 [10]

Answer: The drive theory of motivation.

Explanation:

The drive threory of motivation is based on the principle that organisms have certain psycological or physiological needs (in this case, hunger). When those needs are not satisfied, a tension in the organism is produced, and with it a drive to seek the satisfaction of that need.

Because the substance the rat recieves is nonnutritive (it doesn't reduce the rat's hunger), we can clearly see that the rat isn't performing the response because of this drive, seeking for the satisfaction of its hunger, but is motivated by another feeling. Therefore, this observation is problematic for the drive theory of motivation.

wind energy gaining support as a possible energy source for people. what is the source of the energy that generated wind?
Ivahew [28]

<u>Answer</u>: The energy source that generates wind is actually the sun.

<u>Explanation</u>: The uneven heating of the Earth's surface by the sun gives rise to differences in atmospheric pressure. Areas such as deserts will warm the air masses above much more. As air is heated, it has a lower density as it expands and thus will form a point of low atmospheric pressure. The opposite situation applies for high pressure areas.The air movement from areas of high pressure to areas of lower pressure is what we call wind.

Komok [63]

Answer:

C) protein possesses a signal for localization within the Golgi apparatus.

Explanation:

Protein targeting or sorting is a process by which synthesized proteins are transported to their appropriate localizations in the cell or outside it. Proteins can be targeted to the inner space of an organelle (such as Golgi apparatus or endoplasmic reticulum) or its membrane, plasma membrane, or to exterior of the cell via secretion.  

Usually, protein contains signal sequence on the N terminus that is involved in destination targeting.
