B nearly percent
Explanation:
I had the quiz
E. coli Is a species of bacteria that causes many different Infections in humans. Certain E. coli strains have developed resistance to antibiotics,
making Infections with these strains difficult to treat. How do bacteria such as E. coll, which reproduce asexually, galn new tralts such as
antibiotic resistance?
O A. by adapting to changes in environmental conditions without undergoing changes in their DNA
OB. by mutating their DNA in response to environmental conditions to gain beneficial traits
OC. by undergoing spontaneous mutations when they replicate, which increases genetic variation in a population
OD. by producing offspring with new gene assortments from genetic recombination, which increases diversity in a population
Answer:
The correct answer would be B
Explanation:
Antibiotic resistance in bacteria develops in response to the environment in which the bacteria survives.
The antimicrobial resistance trait is acquired by any species of bacteria through one of the two ways that are either by making changes in their DNA sequences or through horizontal gene transfer mechanisms.
In the given E. coli gained the trait to develop resistance against antibiotic by making changes in their DNA as once the gene is altered or mutated, the trait can be passed on to the offsprings.
Therefore, Option-B is the correct answer.
Answer:
B. By mutating their DNA in response to environmental conditions to gain beneficial traits
Explanation:
Through the process of natural selection, bacteria such as E coli can gain new traits that benefit them.
This can occur when a DNA mutation occurs, where the mutated gene is actually beneficial to respond to environmental conditions.
Then, these bacteria with the gene will survive and produce more offspring with the same gene. This is how E coli can develop antibiotic resistance.
So, B is the correct answer.

The tropical rain forest biome has some of the highest biodiversity on earth how would a decrease in the biodiversity due to deforestation or other factors affect the large biosphere
Answer:
Negatively.
Explanation:
A decrease in biodiversity can cause a large chain reaction within the ecosystem. A loss of species can be detrimental, especially if they're key stone species. This negative impact can cause the food chain to be disrupted which ends up affecting every organism within the environment. Every organism plays a role within the ecosystem and when one or more are removed it causes extreme disarray.
The decrease in biodiversity due to deforestation and other factors in the tropical rainforest biome will negatively affect the biosphere. Thus, the effect will be negative.
What is the biosphere?The biosphere also called the ecosphere is the sum of the total life or the ecosystem. It includes the part of the planet where life is inhabitants. It may include a mountain, roots, dessert, oceans, etc. It is interrelated to biodiversity.
If the biodiversity of a place gets declined due to factors like deforestation, pollution, poaching, natural disasters, etc. then it will affect the ecosystem. If the stone species are lost then it will have a detrimental effect on the ecosystem.
These negative consequences disrupt the food chain and will result in affecting every organism. This chain of disruption will cause an overall loss to the biosphere.

Answer:
DNA has 2 strands and mRNA has 1 strand of nucleotides.
DNA has 2 strands and mRNA has 1 strand of nucleotides.
Deoxyribonucleotides is simply referred to as the fundamental (basic) unit of a deoxyribonucleic acid (DNA).
Basically, deoxyribonucleic acid (DNA) comprises two (2) strands of nucleotides which are arranged in a double helix.
On a related note, a messenger ribonucleic acid (mRNA) refers to a molecule that is complementary to the template strand of deoxyribonucleic acid (DNA).
Hence, mRNA has one (1) strand of nucleotide and it is mainly used for the encoding of protein molecules.
In conclusion, deoxyribonucleic acid (DNA) has two (2) strands of nucleotides while messenger ribonucleic acid (mRNA) has one (1) strand of nucleotide.

The behavior type of response with the corresponding action is instinct-migration, trial and error-putting a puzzle together, conditional response-getting hungry before lunchtime, habit-brushing your hair, and reflex-eye blinking.
What is the corresponding action?The brain control action is regulated by the body some are involuntary and others are voluntary it creates a rhythm in our body to make the system regulate.
Migration is instinct but putting puzzle is a trial and error condition, when the eye is blinked is a reflex action, and crushing your hair is a habit while getting hungry before lunchtime is a conditional response.
All the action of the body is controlled by the body's action some signals are sent to the body to regulate every action to control conditional response or habit.
Therefore instinct-migration, trial and error-putting a puzzle together, conditional response-getting hungry before lunchtime, habit-brushing your hair, and reflex-eye blinking.

What is the use of reverse transcriptase?Reverse transcriptase enzyme has been generally used by the retrovirus for their genome replication. This enzyme has been discovered by the Howard tenim.
Reverse transcriptase enzyme generates the complementary DNA from the mRNA template by the process of reverse transcription. The presence of RNase H, RNA-dependent DNA polymerase and DNA-dependent DNA polymerase activity enable the enzyme to convert the mRNA into DNA.
The position of the mRNA is to carry protein facts from the DNA in a cell's nucleus to the cellular's cytoplasm (watery interior), where the protein-making machinery reads the mRNA sequence and translates every three-base codon into its corresponding amino acid in a growing protein chain.
Therefore, The mRNA sequence will best match the section of DNA shown below is C-U-A-G-G-A. Thus, option C is correct.
