Describe the difference between the messenger RNA transcript produce by rna polymerase in the nucleus and the mRNA transcript that binds to the ribosomal subunits in the endolplasimic reticulum.
Answer:
The mRNA transcript that is produced in the nucleus is in immature form, it had to get matured, and then its capping and tailing is done. 5' cap is added and a poly A tail is added at 3' end of this mRNA. This helps it to get matured. moreover for its maturation the non-coding regions (introns) are removed and exons are packed up again to form a mature mRNA.
This mature mRNA then proceeds to its way to the ribosomes for translation of proteins.
The pre-mRNA transcript is synthesized in the nucleus and undergoes processing including splicing, capping, and polyadenylation to become mature mRNA. This mature mRNA then exits the nucleus and binds to ribosomal subunits in the endoplasmic reticulum for protein synthesis.
The difference between the messenger RNA (mRNA) transcript produced by RNA polymerase in the nucleus and the mRNA transcript that binds to ribosomal subunits in the endoplasmic reticulum involves several key processing steps. The initial RNA transcript synthesized by RNA polymerase II is known as pre-mRNA.
This pre-mRNA undergoes several processing events before becoming a mature mRNA that can be translated into protein. The processing includes splicing to remove introns (non-coding regions), addition of a 5' cap, and polyadenylation, adding a poly(A) tail at the 3' end. These modifications are crucial for mRNA stability, nuclear export, and translation efficiency. Once processed, the mature mRNA exits the nucleus and can associate with ribosomes on the endoplasmic reticulum, forming the protein synthesis complex.

Two scientists do not agree on which type of grocery bag is better for the environment
Answer:
The outcome would be one bag over the other because they would use science to disprove the others argument.
Explanation:
Ok... is this what modern science has come to?
Answer:
Option D Gather more evidence before reaching the conclusion
Explanation:
Several factors might influence the scientists to disagree. For example, one of the reasons could be the safety of the bags. The first one might argue that plastic bags pollute the environment. The second one might argue that plastic bags are not harmful at all.
The other scientists may argue that plastic bags are non-biodegradable and therefore pollute the environment and cause many problems. The other one may argue that plastic bags are now biodegradable. So, the best way is to gather evidence before establishing the correct point.

What do the numbers 3 and 4 refer to in 3NH4?
Answer: 3 nitrogen atoms and 12 hydrogen atoms
Explanation: In a chemical equation, number represents the atoms present. Number at the base of the atom must be multiplied with the number written at the first atom for example 3NH4 so here for Hydrogen 4 is multiplied with 3 i.e. 12Hydrogen but for first atom Nitrogen only 3 is there so 3 nitrogen and 12 Hydrogen is present.

This type of mutation occurs when one or more base pairs are added to the gene sequence. PLEASEEEEE HELPPPPP MEEEE!!!!
Answer:
Insertion
Explanation:
Mutation is a phenomenon in which the nucleotide sequence of a gene in DNA is changed into a new sequence due to insertion, deletion or exchange of a gene segment.
Insertion is a type of mutation in which one or more than pne base sequence in added into the DNA of an organism. This insertion may or may not be dangerous depending on the place of insertion and how it is causing adverse effects on the protein product of the gene.
Here is an example of insertion mutation:
Base sequence: AUG GCC TGC
Product: met ala gln
Insertion:
Base sequence: AUG GCC C TG C
Product: met ala Leu
So we can see that the product protein is changed because of insertion.

what did darwin research? what did he conclude?
Answer:
The diversity of species
Explanation:
Darwin investigated the diversity of species by observing the physical differences between them. He concluded that all the species came from the same ancestor in common. And that the evolution is given by natural selection (or adaptation to the environment). Only specimens more adapted to the environment could survive, reproduce and pass their genetic traits to their offspring.
For example, the long neck of the giraffes is due to the fact that only the highest ones reached the leaves of the trees for food and with that they managed to survive.
This food web represents a community in a rain forest.
boa constrictor
beetle
coati
poison dart frog
sloth
strangler fig -
fungus
fruit bat
If people took most of the boa constrictors from this community, which
changes would be likely to occur? Select the three correct answers.
Answer:
coatis would increase
sloths would increase
fruit bats would increase
Explanation:
The boa constrictor in this food chain is the top predator, thus it is on the top of the food chain. It preys on several of the animals on this list, such as the coati, sloth, and fruit bats, so it is regulating their numbers. If the boa constrictor is removed from the ecosystem, the ecosystem will lose its predator, so the animals on which the boa constrictor preyed upon will have no threat, thus will experience rapid increase in their numbers. The coatis, sloths, and fruit bats, all will be predator free in this scenario, so they will all experience increase in their population, which in turn will have big effect on all other species in the ecosystem.

The circulatory system transports substances such as glucose and oxygen around the body.
(a) Name two other substances that the circulatory system transports around the body.
Answer: blood
Hormones
Amino acids
Electrolytes
Explanation:
The two other components which are transported by a circulatory system are blood and Hormones and Amino acids.
What is circulatory system?Blood arteries in the circulatory system move blood away from and toward the heart. Blood leaves the heart through arteries and returns through veins.
Cells receive oxygen, nutrients, and hormones from the circulatory system, which also removes wastes like carbon dioxide. To keep things moving in the right direction, these roads only go in one direction.
The blood picks up oxygen and releases carbon dioxide at the lungs. The pulmonary veins are then used to transport the blood back to the heart.
Therefore, The two other components which are transported by a circulatory system are blood and Hormones and Amino acids.

which species will most likely survive if earth temperature increase?
Species A: Thick fur with long hair, small ears
Species B: Fur with short hair, large ears protruding out
A. Species A because fur would provide insulation
B. Species B because fur would provide insulation
C. Species A because small flapping ears would provide cooling
D. Species B because large flapping ears would provide cooling
Species B, with its fur with short hair and large ears, is more likely to survive if Earth's temperature increases because large ears facilitate cooling by dissipating body heat into the air, which is crucial in warmer climates (option D).
Species A is characterized by thick fur with long hair and small ears, while Species B has fur with short hair and large ears protruding out. It's important to understand how animals adapt to their environment, particularly through features that allow them to conserve or dissipate heat.
Animals with features such as thick fur and blubber are often found in colder climates because these features provide insulation and help to retain body heat. For example, polar bears and arctic foxes use their thick fur and tails to keep warm in subfreezing environments. Conversely, animals like the jackrabbit with long, tall ears dissipate heat through their ears to help cool off in warmer climates.
When Earth's temperature increases, animals with adaptations that help them dissipate heat are more likely to thrive. Therefore, the correct answer is D. Species B because large flapping ears would provide cooling. Species B's larger ears allow for more heat to be dissipated, which is an advantageous trait in a warmer climate, while thick fur would be detrimental in such conditions.
Species B, with short hair and large ears, would be more likely to survive in warmer climates as large ears help in heat dissipation. Thick fur and small ears, as in Species A, are more adapted to cold climates and conserve heat.
Adaptations to Increased Earth Temperature
Considering the adaptations required for surviving in an environment with increased temperatures, Species B, with fur with short hair and large ears protruding out, is more likely to survive. This is because large ears facilitate the dissipation of body heat, which is crucial in warmer climates. Species like the jackrabbit use their long ears containing dilating blood vessels to release body heat into the air. Conversely, species with thick fur and small ears, like Species A, have adaptations suitable for conserving heat in colder environments.
Furthermore, Allen's rule highlights the trend that animals in warm climates tend to have longer limbs and ears for better heat dissipation. Species B aligns with this rule, having features like large ears that would provide cooling, making it better suited for survival if Earth's temperature increases.

Echolocation is an adaptation bats use to _______. a. hunt insects in flight b. locate flowering plants c. find warm places for hibernation d. all of the above Please select the best answer from the choices provided A B C D
Answer:
d. all of the above
Explanation:
The bats are the only mammals that have managed to perfect flight. They have managed to develop wings, but have started to have a nocturnal life, so in order to be more effective, they have developed their senses like the smell and hearing better, and also developed something new, echolocation. Because the eyesight was not really needed, the bats became almost blind, having very bad eyesight. The echolocation replaced their eyesight though, and it has proven as a very effective adaptation. It is an adaptation that manages to locate objects, food source, be it insects or flowering plants, as well as caves for shelter from predators and cold weather.
what does it mean that a hypothesis must be falsifiable in order to be valid
Answer:
It means that a hypothesis must be able to be rejected by the experiment proposed.
Explanation:
In science, a hypothesis can either be supported or refuted after conducting an experiment. No hypothesis will be valid unless there is a possiblility for it to be refuted by the experiment.
Answer:
It means that a hypothesis could only be considered true or false, not from its verifiability, but from its falsifiability
Explanation:
The scientific observation is always oriented previously by a hypothesis to be proven, that is, the science that is based on the inductive method selects the phenomena that will be investigated for the proof of something that is already supposed. For this reason, the verifiability criterion will not always be valid.
Hypotheses that offer no possibility of being refuted through experience should be considered as myths, not as science. To say that a scientific hypothesis must be falsifiable empirically means to say that a scientific theory must offer the possibility of refutation - and, if refuted, should not be considered.
