What is an anticodon?*
O the bond that holds nucleotides together
O the protein that translates RNA to amino acids
O the abbreviation for amino acids
O three bases on tRNA that attaches to a codon
Answer:
An anticodon is a trinucleotide sequence complementary to that of a corresponding codon in a messenger RNA (mRNA) sequence. An anticodon is found at one end of a transfer RNA (tRNA) molecule.

Answer:
The correct answer is -
transcribed (mRNA) - CCC AUG UGU UGG CAC GUC GGA UGA CCC
Translated - Pro- Meth- Cys-Trp-His-Val-Gly- Stop-Pro
Explanation:
Transcription and translation are two steps of protein synthesis from a particular DNA sequence from a genome. The DNA segment called gene produces specific amino acid chains to form a polypeptide chain of the protein.
Transcription is the process that produces mRNA molecule from the DNA sequence that is complementary to the nitrogen base present in the sequence. The only Change in the nitrogen sequence that Adenine changes into uracil, thymine to adenine, cytosine to guanine, and guanine to cytosine.
DNA - G G G T A C A C A A C C G T G C A G C C T A C T G G G
mRNA - CCC AUG UGU UGG CAC GUC GGA UGA CCC
Translation on other hand is the process of translating the encoded information in mRNA molecule to amino acids with help of tRNA and ribosomes.
mRNA - CCC AUG UGU UGG CAC GUC GGA UGA CCC
Translated - Pro- Meth- Cys-Trp-His-Val-Gly- Stop-Pro
a scientist begins working by trying to explain a natural occurence that is...
1. consistent
2. observable
3. In a lab
4. undetectable
Answer:
Observable
Explanation:
An observable phenomenon leads to an hypothesis.
Answer:
2. observable
Explanation:
The scientific method relies on a scientist being able to study an occurrence and understand it. So, all the occurrences must be observable; otherwise, they cannot be studied. If the patterns are observable then one can follow the scientific method and experiment with the different variables. All science depends on the observable world and the people that study it.

3 Loam soils generally contain more nutrients, moisture, and humus than sandy soils, have better drainage and infiltration of water and air than silt and clay-rich soils, and are easier to till than clay soils.
4 Soil organisms represent a large fraction of global terrestrial biodiversity. They carry out a range of processes important for soil health and fertility in soils of both natural ecosystems and agricultural systems.
5 Soils provide anchorage for roots, hold water and nutrients. Soils are home to myriad micro-organisms that fix nitrogen and decompose organic matter, and armies of microscopic animals as well as earthworms and termites. ... Soil plays a vital role in the Earth's ecosystem. Without soil human life would be very difficult.

The difference between the bats in the United States with the Pd fungus and bats found in Europe and China with the Pd fungus was that A. the bats in the United States were immune to the fungus. B. the bats in the United States had a more deadly form of the fungus. C. the bats in Europe and China were dying at a faster rate. D. the bats in Europe and China were healthy.
Answer:
The correct answer is - D. the bats in Europe and China were healthy.
Explanation:
The white-nose disease of bats is caused by the Pseudogymnoascus destructans or Pd fungus that found in cold mines and caves of the bat. It is a fatal disease that leads to the destruction of the bat population in the United States, in north Calorina the population was dropped up to 99 percent. The bats found in Europe and China with the Pd fungus were healthy and do not cause any fatal disease in the population.

Throughout the world, in nearly every ecosystem, there are animal and plant species present that were introduced into the ecosystem by humans or transported to the ecosystem as a result of human activities. Some examples are listed in the chart below. 41. State one reason why an introduced species might be very successful in a new environment. [1] ________________________________________________________________ ________________________________________________________________ 42. Identify one action the government could take to prevent the introduction of additional new species. [1]
Answer:
Suitability of environment and tolerance.
Explanation:
Suitability of environment and tolerance is the reason which tells that an introduced species might be very successful in a new environment. The species have all the adaptations that helps in the survival of introduced organism. Strict checking on the airports and destruction of plant species that the person bring with it are the actions take by the government that prevent the introduction of additional new species in the ecosystem.

The difference between pectin an amylopectin is that
1. Pectin has more branching
2. Amylopectin has a - 1,4 glycosidic bonds and pectins have a - 1,6 glycosidic bonds
3. Amylopectin has more branching
4. Amylopectin has a - 1,4 glycosidic bonds and pectins have ß - 1,4 glycosidic bonds
The difference between pectin and amylopectin is that amylopectin has more branching than pectin.
What is pectin?"Pectin consists of a complex set of polysaccharides." This has a linear chains of α-(1–4)-linked D-galacturonic acid.This are mainly found in plants.This helps in binding cells together.What is amylopectin?"Amylopectin is a highly branched macromolecule composed mostly of α-(1→4)-d-glucopyranose units, with α-(1→6)-linkages at intervals of approximately 20 units."These are water insoluble.Hence, the correct option is 3. Amylopectin has more branching.

15. the image below shows chromosomes in a human cell
i need answer a, b and c please!
This representation called as karyotype, the gender of the individual is male and this individual have the correct number of chromosomes.
What are chromosomes?Each cell's nucleus contains chromosomes, which are structures that resemble threads and contain the DNA molecule.
Each chromosome is constructed from DNA that has been tightly wound around proteins called histones numerous times to support its structure.
a component that can be found in a cell's nucleus. Proteins and DNA are arranged into genes on a chromosome. There are typically 23 pairs of chromosomes in each cell.
An individual's entire set of chromosomes is known as their karyotype. The phrase can also refer to an image created in a lab showing a person's chromosomes separated from one cell and organized in numerical order.
Present-day female humans have a single set of identical X chromosomes. Instead of a matched pair, male humans have one larger X and one smaller Y chromosome.
Thus, this image, known as a karyotype, shows that the person is male and has the appropriate amount of chromosomes.

How do mountains play a role in precipitation patterns?
a. As water vapor condenses,the air gets warmer b.it changes the amount of rain received c.it changes the direction of the wind d.as vapor condenses,it depends rain or snow on windward slopes
Answer:
a. As vapor condenses, it depends (specifically; leads to) rain or snow on the windward slope
Explanation:
The orographic effect which is the changes in masses of air as it moves along the mountain sides, up or down is the way the mountains have an effect on the climate
The orographic effect of mountains can be analyzed based on either the windward side, (which is the side that faces the incoming wind), or the leeward side (which is the opposite side of the mountain)
The moist and warm air from the oceans and other large water bodies are carried by wind onto the mountains where the moist wind is directed upward by the obstructing mountain wall.
As the elevation of the warm moist wind increases along the mountain, the cooler temperatures at the high altitudes forces the air to cool down, until the dew point is reached, which leads to precipitation of rain or snow.

Some species form social groups only with members of the same gender. For example, elephants form groups with only females and their offspring. Once the male offspring reach a certain age, they leave the group and become solitary.
Which is a benefit of this type of social group structure?
Females do not have to compete for a mate.
Male offspring can belong to more than one social group.
Adult males can mate with females in several different social groups.
Females are the only ones responsible for taking care of the offspring.
Answer:
Females do not have to compete for a mate.
Explanation:
Due to grouping of animals, females do not have to compete for a mate because each group has its own male. They have a male with which she mate and produce fertile offspring and has a complete family so we can say that the benefit of such type of social group structures is that females do not have to compete for a mate in the population as compared to other animals.
Answer:
A. female's do not have to compete for mates.
