Carbohydrates like glucose can undergo spontaneous rearrangement to give an alternate configuration for the anomeric carbon when the ring is free in solution. However, when glucose is covalently attached to another sugar through C1, this rearrangement cannot occur. Consequently, the configuration of carbohydrate oligomers and polymers is fixed. Why can't glucose rearrange when in a polymer form?

Answers

Answer:

The presentation according to another circumstance is categorized in the following section.

Explanation:

Glucose constructs anomers because of the extreme involvement of flexible metal-carbon because that continues to exist as something of a monomer. However, when plastics are established, transformation is limited with glycoside formation of complexes among both anomeric carbon atoms.

Sucrose, besides obvious reasons, would be manufactured by glucose and fructose, which have been connected by something like a glycerol backbone involving glucose carbon atom as well as fructose. The mechanism including its creation of anomers even by movement through carbon becomes called "Mutarotation" Sucrose doesn't always show mutation.

Some organisms, such as bacteria, reproduce asexually; whereas, other organisms reproduce
sexually. Which statement correctly states why one type of reproduction is beneficial over the
other?
A. Asexually reproduced offspring are more genetically diverse.
B. Asexual reproduction produces offspring genetically different from parents.
C. Sexual reproduction can produce a large number of offspring very quickly.
D. Sexual reproduction produces organisms that are genetically diverse.

Answers

Answer:D

Explanation: A isn't right because during asexual reproduction there is no exchange of genetic characteristics thus the offsprings retain the genetic characteristics of their parents and there is no diversity.

Sexual reproduction on the other hand involves the fusion of gametes and the exchange of genetic characteristics thus the offsprings are diverse and are not identical to their parents as is the contrary in asexual reproduction.

Sexual reproduction produces organisms that are genetically diverse.

Sexual reproduction involves the combination of chromosomes from both parents. This combination of chromosomes introduces variation into the population. This combination does not occur in asexual reproduction.

Hence, the statement that correctly states why one type of reproduction is beneficial over the  other is that sexual reproduction produces organisms that are genetically diverse.

b. unicellular

c. autotrophs; heterotrophs

Explanation:

Protists represent a separate kingdom of eukaryotic organisms (ie., organisms whose cells have a nucleus). The most important features of protists include: 1- they are unicellular organisms, 2-contain mitochondria, 3-can be parasites, and 4-generally live in optimal conditions in moist or aquatic environments. In the past, protists were divided into Protozoa (animal-like organisms) and Protophyta (plant-like organisms), which nowadays we know are heterotrophic (also often parasitic) and photosynthetic protists, respectively.

Answers

Answer:

stores extra food

is responsible for photosynthesis

supports the plant

makes up the majority of a plant

Explanation:

Ground tissues are one of the three types of plant tissues (others being dermal and vascular). They are composed of cells as follows: parenchyma, collenchyma, and sclerenchyma. These three cells that make up the ground tissues perform different functions in the plant cell.

- Parenchyma functions in photosynthesis and storage of extra food (carbohydrates) in the cell.

- Collenchyma functions in the support of young regions of the plant

- Sclerenchyma, which has the thickest cell wall, functions mainly in the strengthening/support of the plant cell.

Also, among the three tissue types in a plant, ground tissues make up majority of the plant cell.

There is a multitude of evidence that supports how life has changed over time due to variation in the gene pool of different species. Which of the following choices below represents a scientific theory that explains these changes? *
A. As environments and ecosystems change over time, those that acquire suitable traits are more likely to survive and reproduce and the gene pool changes because organisms must adapt to survive and reproduce.
B. As environments and ecosystems change over time, those with variations for traits that are more successful in the new conditions are more likely to survive and reproduce, thus changing the allele frequency in the gene pool.
C. Because the environments and ecosystems show little change over time, organisms are already adapted for surviving in their given habitats for which they are made.
D. Because the environments and ecosystem show little change of time, the organisms that choose to adapt to different environments will migrate and become suited for new habitats.

Answers

Answer: A. Environmental drivers plus genetic variation in the population result in natural selection

Explanation: over geological time environmental conditions change. Organisms do not survive in one environmental niche with traits adapted to a possible future change that might suit those traits. Adaptation is not a matter of choice: adapt if possible or go extinct.

There is a (badly named) concept called pre-adaptation, which is that variations in some existing trait render adaptation to a different environment more likely.
