Maria is concerned because she has been exposed to a small amount of radiation during an X-ray. What is her doctor most likely to tell her?

Answers

Answer 1

Answer:

The doctor should reassure the patient that exposure to radiation from a medical device becomes dangerous only if it is exposed for a long time, in high doses, or repeatedly.

It is true that there is a particular risk for pregnant women with regard to the fetus. In this case, the ratio between the benefit to the patient and the possible risk of side effects should always be taken into account.

Answer 2

Answer: Many people have been exposed to radiation- and that she shouldnt be worried because the amount of radiation she was exposed to was very little and most likely wont effect anything or anyone.

Determine which strand is transcribed, indicate the polarity of the two DNA strands, and then give the sequence of bases in the resulting mRNA and its polarity.

Answers

A strand that is transcribed is called a template strand, the other one is called a coding strand. The template strand is in 3'-5' direction, and the coding strand is in 5'-3' direction. mRNA is transcribed from 3'-5' template DNA strand, so it is in 5' to 3' direction. The first codon of mRNA is called start codon and usually it is AUG.

Knowing this, we can answer the questions:

The transcribed strand must contain three nucleotide sequence complementary to AUG codon. According to the base pairing rules, it must be TAC. The strand that contains TAC, and, thus, is transcribed is
C C C T A C G C C T T T C A G G T T.
This template strand is in 3'-5' direction and the other one is 5'-3'.
mRNA transcription begins from the DNA sequence complementary to AUG codon:
DNA sequence: 3' C C C T A C G C C T T T C A G G T T 5'
mRNA sequence: 5' A U G C G G A A A G U C C A A 3'
mRNA sequence is in 5'-3' direction.

yeast
penicillium
aspergillus
Rhizopus stolonifera

Answers

The correct answer is:

Penicillium

Aspergillus

The lesson states:

If you've ever heard of or taken penicillin to fight off an infection, you can thank a member of the imperfect fungi called penicillium. Some mold species of penicillium are also important in the flavoring and aging of cheese. Roquefort and Camembert cheese owe their distinctive flavors to these fungi. Aspergillus is an imperfect fungus that is found on decaying food. It also contributes to the production of organic acids like citric acid. Both penicillium and aspergillus produce enzymes that are purified and used in various industrial compounds and in medicine.

Explain why DNA has an overall negative charge.

Answers

DNA has an overall negative charge because DNA backbones are made of deoxyribose and pentose sugar which are connected in phosphodiester bond. The groups of phosphate usually have a negative charge that makes positively charged particles (histone proteins) to interact and form chromatin.

A wildlife biologist suggests re-introducing the eastern cougar into southern Alabama, reasoning that besides bears, which can survive off of berries and grubs, there are no large natural predators, and that it would be good for the food chain. It is assumed that the eastern cougar would eat deer, which in turn, graze on tree bark, shrubs, and leaves. The average cougar weighs about 100 pounds, as does the average deer. The average cougar has a range of one square mile. A recent biological study showed that there were about 16 deer per square mile in Alabama, an average about 40,000 pounds of vegetation per square mile, and an average of 9.5 people per square mile in southern Alabama. Despite the biologist's proposal, other biologists vote against re-introducing the cougar. Which of these is a possible VALID reason for this?

Answers

The biologists are worried that the cougar will be harmed or harm people's in the cougar's range.

because since it only has one natural predators and not more when it start reproducing there will be no predator to keep the population in check which then later can mess up the whole ecosystem or something. I am not sure though.

If lactose is present,would the lac operon in bacterial cell be on or off? Explain

Answers

Explanation:

The lac operon

When lactose is present, bacteria need the enzymes to break it down. But if no lactose is present, bacteria do not need to waste resources making enzymes to break down a sugar that isn't there. Like a switch, the operon is turned on when the enzymes are needed.
