Explanation:
The process of transcription begins when an enzyme called RNA polymerase (RNA pol) attaches to the template DNA strand and begins to catalyze production of complementary RNA.
What is the main difference between active transport and passive transport?
(A) During active transport the water inside the cell is used to transport substances throughout the cell. Passive transport uses the cell's cytoplasm to move substances around the cell.
(B) Passive transport moves substances throughout the cell without using the cell's energy and active transport moves substances using the cell's energy.
(C) Active transport moves substances from higher concentrations to lower concentrations and passive transport moves substances from lower concentrations to higher concentrations.
(D) Passive transport moves substances that are too large to get through the cell membrane by forming a vesicle inside the cell and active transport forms the vesicle on the outside of the cell.
Answer:
B
Explanation:
passive transport uses diffusion to transport while active transport uses some energy most commonly atp
Arturo ran a 3,000-meter race. His running time from start to finish was 10 minutes. What was Arturo's average speed?
Answer:
300 meters/min
Explanation:
average speed = distance / time
(3000 m) / (10 min) = 300 meter per minute
if you need it in meters/sec then just multiply 10 by 60 first and then continue
(3000 m) / (600 sec) = 5 m/s

tRNA uses (anticodons/codons) to match to the mRNA.
Answer:
anticodons
Explanation:
codons are for mRNA
tRNA uses anticodons to match to the mRNA.
Which one does tRNA uses?tRNA (transfer RNA) molecules are responsible for carrying specific amino acids to the ribosomes during protein synthesis.
They have an anticodon region that consists of three nucleotides that are complementary to the codons on the mRNA (messenger RNA). The codons on the mRNA determine the sequence of amino acids in the growing polypeptide chain.
The anticodon on the tRNA base pairs with the complementary codon on the mRNA, ensuring that the correct amino acid is incorporated into the growing protein chain. The matching between the anticodon and codon is essential for the accurate translation of genetic information into protein synthesis.

Which section of the article BEST explains why the development of CRISPR-Cas9 is significant for the scientific community?
Answer:
It allows the scientists to activate gene expression instead of cutting the DNA.
Explanation:
The development of CRISPR-Cas9 is significant for the scientific community because this development allows the scientists to activate gene expression instead of cutting the DNA. This technique allows the scientists and researchers to study the function of the gene. Before development, Cas9 enzymes produced by the CRISPR system binds to the DNA and cuts it by shutting the targeted gene off so this development of CRISPR-Cas9 enables the scientists to activate gene expression instead of cutting the DNA.

If you have a hamster with long fur, what possible genotypes could the hamster have?
Answer:
Ll, Ll, LL
Explanation:
So, there is one thing we must remember to answer this:
1# dominant genes(long fur) are expressed over reccesive genes(short fur)
Knownign that dominant is over reccesive, it is simple. If the genotype was Ll or lL then the dominant long fur would be expressed over reccesive short fur. Long fur - Ll, lL
Next, we know that LL will be long fur since its both long and long, and there is no possibility for short fur. Long fur - LL
Finally. we have ll, and since there isnt a dominant long fur, and only reccesvie short, then this cannot be long fur. Short fur. - ll

Which conclusion is supported by the fact that the black-breed boar, with its quality meat, and the white-breed sow, with its quality fertility, are swine that are often matched for mating? Animals are often paired based on physical traits and personal compatibility. Strong reproductive capability is the most important trait in animal breeding. Selective breeding combines ideal traits of animals to replicate in offspring. Swine are the only agricultural animal species that are currently crossbred.
Answer:
Selective breeding combines ideal traits of animals to replicate in offspring
Explanation:
Selective breeding is the process which involves choosing parents with particular characteristics to breed together and produce offspring with more desirable characteristics. It is also known as artificial breeding and provides both plants and animals with greater variation and higher chances of survival. Selective breeding can be used to produce plants with bigger and tastier fruits and vegetables, crops with greater resistance to pests and diseases, and bigger animals that can be used for meat or milk production. The process of selective breeding is of great importance to the farmer today as it has brought about greater economic advantages.
In the instance of the black-breed boar and the white-breed sow being matched for mating, the reason is to combine these desirable traits in their offspring. The black-breed boar produces quality meat while the white-breed sow has quality fertility. Mating between these two breeds will produce offspring which has both traits of quality meat production as well as quality fertility.

List one organism and describe all of its adaptations.
Adaptation is a mechanism of species to survive and reproduce in their environments, adjusting to selective pressures. Cactus: leaves, stems, spines.
What is adaptation?
In biology, adaptation might be defined as the mechanism of organisms to improve their fitness in the environment in which they live, adjusting to different changes and selective pressures acting on them.
Adaptation involves molecular, physiological, morphological, and behavioral changes.
For these changes to persist and be transmitted from generation to generation, they must increase the individual's fitness. They must increase the individual survival and reproductive probabilities, making it more competitive.
A good and easy to unsderstand example of adaptation is the cactus.
Cactusses are plants adapted to dry and hot environments like deserts, where water availability is scarse and temperatures are high.
To avoid dehydration, cactusses have developed wide palmated or cilindirical stems and reduced or vestigial leaves.
They use stem tissues to store water. Vestigial or reduced leaves to avoid transpiration and water loss.As their leaves are not developed, their stems photosynthetize to produce organic compounds.
Some species are very rich in water and nutrients, so they turn to be covetted by other species. Animals living in the same environment look for them as a source of food.
To avoid predation, cactusses have developed large and numeros spines that are leaves modifications. This is another adaptation to avoid being eaten by animals and avoid loosing water through leaves.

The best explanation for the presence of vestigial pelvis and femurs in some snake and whale species is
Answer:
a common ancestor that used these structures to perform one or more specific functions
Explanation:
A vestigial structure is an organ that has no obvious function in an organism, but it has been used by a past ancestor to perform one or more specific functions. Thus, vestigial structures have been retained in the course of evolution, but they lost their ancestral functions. Vestigial structures/organs can be detrimental for the organism because it is required energy to maintain them and they may suffer diseases (e.g., cancer). Some well-known examples of vestigial organs/structures include, among others, the wings of ostriches and cormorants, the human appendix, etc.
