What are similarities and differences between the structures of DNA and RNA?

Answers

Answer:

The similarities and differences between DNA and RNA are given as follows:

Explanation:

Similarities:

Both are made up of nucleotides

Nucleotides are made up of nitrogenous bases, a pentose sugar, and the phosphate backbone.

Both DNA and RNA have four nitrogenous bases each - two purines two pyrimidines

Purine binds with pyrimidines

Differences

DNA uses the nitrogenous bases adenine, cytosine, thymine, and guanine whereas RNA uses adenine, cytosine, uracil, and guanine. Uracil lacks a methyl group on its ring

RNA contains the sugar ribose that has an extra -OH while DNA contains the deoxyribose sugar that has H at the 2 carbon.

DNA is double-stranded while RNA is a single-stranded

Under alkaline conditions, DNA is stable while RNA is not stable.

Habitat isolation occurs when habitat preferences lower the probability of mating between individuals associated with differing habitats. While a potential barrier to gene flow during ecological speciation, the effect of habitat isolation on reproductive isolation has rarely been directly tested.

10. Deafness in cocker spaniels is inherited. The allele for deafness (d) is recessive to the allele for hearing (D). Two cocker spaniels that are heterozygous for hearing are mated together. What is the chance that a puppy will be deaf?

Question 10 options:
0%
25%
50%
100%

Answers

Answer:

25%

Explanation:

If they are both heterozygous, it means they both have a Dd genotype. If you draw out a punnet square Dd x Dd you end up with the following possible genotypes for the puppy:

DD, Dd, Dd, dd

In order for the puppy to be deaf, it must be dd since deafness is recessive, which is 1/4 (25%)

The chance that the puppy will be deaf is 25%. The correct option is B.

What is allele?

The term "allele" refers to the alternative form or versions of a gene. People inherit one allele for each autosomal gene from each parent, and we tend to categorize the alleles.

We usually refer to them as normal or wild-type alleles, or abnormal or mutant alleles.

If they are both heterozygous, they have the Dd genotype. As per the Punnett square Dd x Dd, one can see the the following genotypes for the puppy:

DD, Dd, dD, dd

Because deafness is recessive, the puppy must be dd, which is 1/4 of the population.

Thus, the correct option is B.

what is the importance of the sense of smell when we are in the science loboratory​

Answers

Answer:

because some chemical reactions release gases which may be odourless or may have smell, in order to identify it it is necessary to have a good sense of smell.

Smell is vital for survival of most humans and animals as it enables them to track food and water, find a mate and even communicate. Although our sense of smell is not as acute as other animals we know that humans are able to detect up to 10,000 different odor molecules.

R. Scientific errors are factors that could have contributed to the uncertainty in the outcome of your experiment. Could measurements have been more accurate? Could you have performed more trials? Could environmental factors, such as the lab's lighting or temperature, have had an effect? State these possible sources of error and analyze or estimate how much they may have affected your results.

Answers

Answer:

Yes.

Explanation:

Yes, measurements should be more accurate if these scientific error are removed. Yes, we must perform more trials in order to verify the experiment. Environmental factors, such as the laboratory's lighting or temperature, has a great effect on the experiment and can cause error. In this experiment the errors occur such as instrumental, environmental, procedural, and human. All these error causes inaccurate readings of experiment so greatly affect the experiment.

What might happen at the cellular level of the plant if there was no water available for photosynthesis?

Answers

Answer:

when water levels are low due to water stress, photosynthesis can slow or even stop, causing internal food supplies vital to other processes to diminish or disappear -- yellowing may also occur if photosynthesis stops completely.

Explanation:

If there was no water available for photosynthesis, the cellular level of the

plant will be affected negatively in areas such as shrinking of cells and

decrease in photosynthetic activities.

Plants require water to produce food in the process known as

photosynthesis. When there is no water the photosynthesis is slowed down

and the cells begin to shrink.

The shrinking of cells then results to the wilting and yellowing of leaves of the plant.
