A. Reusing a steel water bottle at a water fountain
B. Buying a new plastic water bottle and throwing it away
C. Drinking directly from a water fountain or from a sink
D. Using a disposable paper cup to get water from your sink
Buying a new plastic water bottle and throwing it away has the most harmful impact on the environment. Thus, the correct option is B.
What is BPA?Hard plastics, such drinking water bottles and numerous home objects, contain the chemical BPA. According to research, BPA exposure can cause the endocrine system to malfunction. However, the average person's daily exposure levels are unlikely to cause substantial harm.
Using non-BPA-free water bottles and failing to properly dispose of them in a trash can would be the activity that would have the most detrimental effects on the environment.

Each has a dog from the pound, and both dogs are less than one year old. Pablo feeds his shepherd-mix dog a special diet of wet and dry foods from the local vet, while Johanna uses generic dry kibble from the supermarket for her bulldog. They want to see which diet results in bigger, healthier, faster-growing dogs. The reason the instructor gives them will include the fact that they have too many ______
Answer:
The correct answer is - variables that they didn't control and not enough replicates
Explanation:
In this particular case, Pablo and Johanna using too many variables in their experiment or research, All the variables used, are not controlled and with time these variables can not be replicated again on experiment groups.
They did not select a particular age or weight of dogs, the diets are different and they feed dry kibble to only one dog. There are so many variables and for a better result experiment, all variables should be controlled only the independent variable is permitted to manipulate.

How do weathering and erosion work together to change or build landforms
Answer:
Erosion is another geological process that creates landforms. When mechanical and chemical weathering breaks up materials on the Earth's surface, erosion can move them to new locations. For example, wind, water or ice can create a valley by removing material. Plateaus can also be formed this way.

Answer:
75% brown, 25% white
Explanation:
This question involves a single gene coding for color in chickens. The allele for brown color (B) is dominant over the allele for white color (b).
According to this question, a brown rooter with genotype 'BB' was crossed with a white hen (bb). The offsprings in the F1 generation will all possess the 'Bb' genotype and be brown colored. However, if these F1 offsprings are self-mated i.e Bb × Bb, the proportion of F2 offsprings will be 1BB, 2Bb, 1bb.
Since BB, Bb and Bb offsprings are Brown in color and bb is white in color, this means that the expected phenotypic appearance of the F2 offsprings will be:
¾ or 75% brown and ¼ or 25% white
Why do organisms that fertilise internally tend to produce less eggs?
Answer:
Explanation: Internal fertilization has the advantage of protecting the fertilized egg from dehydration on land. The embryo is isolated within the female, which limits predation on the young. ... Even though fewer offspring are produced through this method, their survival rate is higher than that for external fertilization.

vinosum is most closely related to which organism
Answer:
Radiodurans, thermophilius
Explanation:
A Vinosum is most closely associated with the thermophilus and the Radiodurans.
What do you mean by Vinosum?Vinosum may be defined as a gram-negative bacteria which is rod-shaped in structure, anoxygenic in nature, and categorized under purple-sulphur bacteria.
Vinosum bacteria are thermophilus which means they survive at relatively high temperatures. They are halotolerant which means they survive in extremely high salt concentrations.
Therefore, a Vinosum is most closely related to the thermophilus and the Radiodurans.

With over 600 muscles in the body we are able to do an array of motions. What is the difference between what big muscles, like the four in the quadriceps, can do and what those like the thirty in our hands can do?
The functions of each muscle depend on its location and ability to perform specific work. For example, the masseter muscle is the strongest muscle in humans which is present in the jaw.
What is the significance of muscles?The significance of muscle is understood by the fact that these structures are linked to bones, internal organs, and blood vessels. These components are responsible for movement by their contractions.
According to the context of this question, the muscles in the shoulder region are the four rotator cuffs which significantly include the supraspinatus, infraspinatus, teres minor, and subscapularis. The four muscles in the quadriceps have to perform a different function which includes heavy weightlifting, so, they have to strongest enough.
While the thirty muscles present in the hand can do numerous functions with different levels of intensity. These muscles are not too strong as compared to masseter but are superior.
Therefore, the functions of each muscle depend on its location and ability to perform specific work.

B) human insulin is less likely to cause harmful side effects than cow, pig, or horse insulin.
C) cow, pig, or horse insulin cannot keep a diabetic alive for more than three months.
D) there are too few cows, pigs, and horses to provide an adequate supply of their insulin.
The advantage of being able to clone the gene for human insulin is that using human insulin increases the probability that, in the future, the person suffering from diabetes can be weaned from a dependence on insulin. Thus, option A is correct.
What is clone?The term clone has been defined as the exact copy of organism. The first clone is the dolly ship which has been created in the scientific manner. Human insulin is less likely to cause harmful side effects than cow, pig, or horse insulin.
There are too few cows, pigs, and horses to provide an adequate supply of their insulin and by using human insulin increases the probability that, in the future, the person suffering from diabetes can be weaned from a dependence on insulin.
Genetically engineered insulin is the synthetic human insulin which has been manufactured from the DNA sources in the laboratory. One advantage of the using genetically engineered insulin has been that it causes fewer allergic reactions as compared to animal insulin.

in prokaryotes certain proteins act to regulate genes by binding dna, what could be the effect of these binding proteins?
Answer:
This question lacks options, the options are:
A. They may act to turn on gene transcription.
B. They may act to turn off gene transcription.
C. They may become added to DNA, and then be transcribed.
D. They may remove a gene from DNA.
E. They may alter the nucleotide sequence in a gene.
Options A and B are the answers.
Explanation:
Prokaryotes regulate gene expression at the transcriptional level. Gene expression is the process whereby living organisms synthesize useful products such as protein from a gene. Prokaryotes such as bacteria control the expression of their genes via proteins that bind to DNA called REGULATORY PROTEINS.
These regulatory proteins also known as TRANSCRIPTION FACTORS, act to regulate genes by binding DNA. The binding of DNA either prevents or promote the binding of RNA polymerase in order for transcription to occur.
- Regulatory proteins which may act to inhibit transcription of DNA by turning off gene are called REPRESSORS.
- Regulatory proteins which may act to promote transcription of DNA by turning on gene are called ACTIVATORS.
