Answer: A. DNA is transcribed into RNA, which is translated into protein
Explanation:
The process of gene expression is the information from DNA is transcribed into RNA, then this RNA is translated into protein.
What is gene expression?Gene expression is the process of directing protein synthesis by utilizing the genetic information encoded in genes (DNA). Gene expression enables organisms to develop various cell types and adapt to internal and external influences.
The process of gene excretion takes place in the cell nucleus and cytoplasm and is divided into two stages: transcription and translation.
DNA is employed in the transcription process to create copies in the form of mRNA. While translation is the process by which individual polypeptides are synthesized in the ribosome. Protein can be made up of one or more polypeptides.
Therefore, the information from DNA is transcribed into RNA, which is then translated into protein during the gene expression process.

What is an ecosystem?An ecosystem is a geographical area in which plants, animals, and other species, as well as weather and scenery, coexist to produce a life bubble. Ecosystems comprise both biotic (living) and abiotic (nonliving) components.
Plants, animals, and other species are examples of biotic factors. A marine ecosystem, for example, contains 32% of the world's producers because water covers three-thirds of the earth's surface and provides a natural habitat for a diverse range of small and large living species and plants.
Therefore, the correct option is c. creativity born from interactions with nature.

write a description of the ecosystem including biotic and abiotic factors? plz
Answer:
The correct answer is - Biotic factors are any living factors and abiotic factors are anything non-living in an ecosystem.
Explanation:
An ecosystem consists of all living organisms, non-living organisms that are present in a physical environment in a particular geographical area. The physical environment consists of several factors such as landscape, pH, climate, salinity, and other factors that represent abiotic factors.
Any living organism present in an ecosystem is biotic factor Examples of biotic factors include are mammals, birds, trees, microbes, grasses, fish, bacteria, and many more.
4. Many of your body’s responses operate off of either negative or positive feedback loops. When you are cold, you shiver. Explain why that happens.
Answer:
The tendency to maintain a stable, relatively constant internal environment is called homeostasis. The body maintains homeostasis for many factors in addition to temperature. For instance, the concentration of various ions in your blood must be kept steady, along with pH and the concentration of glucose. If these values get too high or low, you can end up getting very sick.
Homeostasis is maintained at many levels, not just the level of the whole body as it is for temperature. For instance, the stomach maintains a pH that's different from that of surrounding organs, and each individual cell maintains ion concentrations different from those of the surrounding fluid. Maintaining homeostasis at each level is key to maintaining the body's overall function.
Explanation:
shivering burns fat to help keep one warm
Homeostasis typically involves negative feedback loops that counteract changes of various properties from their target values, known as set points. In contrast to negative feedback loops, positive feedback loops amplify their initiating stimuli, in other words, they move the system away from its starting state.

Describe how amino acids are categorized by their chemical properties. Explain how a change in the amino acid sequence of the FXR1 protein could decrease the ability of the protein to bind to RNA .
Answer:
The nature of amino acids can vary they can be acidic, alkaline, or neutral based on the functional group attached to their side-chain. The functional group of the amino acids determines the property of the hydro loving or phobic nature of particular amino acids. Interaction of different biomolecules depends on their affinities with one another such as hydrogen bonds, ionic bonds, van der Waals interaction based on structural and fundamental unit or monomer of the biomolecule.
Based on the given explanation, we can say that if there is a modification in the sequence of the building block amino acid of the FXR1 protein, might lead to a decrease in affinity to bind to the RNA by changing in the binding domain of this protein. There might be a complete structural change such that it can no longer interact with RNA.
Amino acids are grouped on the basis of their side chains.
Amino acids are categorized on the basis of their side chain attachment. All the amino acids has a specific side chain which is known as an R group. This R group is also attached to the α carbon. The R groups consist of shapes, sizes, charges, and reactivities. This allows all amino acids to be grouped or categorized on the basis of their chemical properties of their side chains.
If there is a change occur in the sequence of the building block amino acid of the FXR1 protein, it might lead to a decrease of binding to the RNA. There might be a complete change in the structure which leads no more attachment with RNA so we can conclude that amino acids are grouped on the basis of their side chains.

Answer:
A. 17,100
Explanation:
The half life of carbon-14 is around 5,700 years. When the shell contains 50% of its original carbon-14, 5,700 years have passed. 25% means another 5,700 years have passed, meaning 11,400 years in total have passed. 12.5% means another 5,700 years have passed, meaning 17,100 years have passed in total.
In feedback inhibition, does an enzyme’s substrate attaches to an allosteric site?
Answer:
They bind to an allosteric site which induces a conformational change that increases the affinity of the enzyme's active site for its substrate. This increases the reaction rate.
Ecological interactions can be categorized as competition, exploitation, or positive. Describe the types of interactions that fall into these categories, and provide an example of each type of interaction.
Answer:
Competition is an interaction between organisms or species in which both the organisms or species are harmed. Limited supply of at least one resource used by both can be a factor. This example is if two lions get into a fight and they end up hurting each other.
Exploitation competition occurs when individuals interact indirectly as they compete for common resources, like territory, prey or food. An example of this is when people are farming and they are trying to get the best food available but someone else might have already gotten it.
Commensalism is a positive type of ecological interaction between two species in an ecosystem. In commensalism, the association occurs between members of two different species where one species is benefited the other is neither benefited nor harmed. An example of this is tree frogs who use trees as protection.

Answer:
Secondary succession
Explanation:
A secondary succession is when a type of disturbance happens when there is already soil present. In this case, it has already started out with a forest (including plants, trees, and wildlife). Other examples of a secondary succession include a wildfire, hurricane, flood, or human destruction.
This is different from a primary succession. A primary succession occurs when there is no soil present.

Answer:
Geocentric ModelEarth is at the center
Includes five planets.
The orbits of the planets are circular,
Heliocentric ModelThe Sun is at the center of the solar system.
The orbits of the planets are elliptical
Includes eight planets.
The solar system
Explanation:
The main difference between the heliocentrical and geocentrical model is that in the first one, the Sun is in the center and the planets are around it, while in the second model, the Earth is in the center and the Sun, the moon, and the planets are around it.
Also, the geocentrical model stated that there were five planets, Mercury, Venus, Mars, Jupiter, and Saturn. These planets had circular orbits. In other words, they have a circular motion around the Earth, and this one was still in the center of the system.
In the heliocentric model, there are eight planets, Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune, and they all rotate in elliptical orbits around the Sun. The Heliocentric model is also called the solar system since its central star is the Sun, and the planets are around it.
How would the Earth's climate change if its obliquity shifted from 23.4° to 0°, and all other factors remained the same?
A-Global warming would increase rapidly.
B-It would shift the Earth into a global ice age.
C-The seasonal changes would be more extreme.
D-There would be no seasons.
Answer:
There would be no seasons.
Explanation:
The tilt of the Earth's axis is what causes seasons. Throughout the year, different parts of Earth receive the Sun's most direct rays. So, when the North Pole tilts toward the Sun, it's summer in the Northern Hemisphere. And when the South Pole tilts toward the Sun, it's winter in the Northern Hemisphere. If there was no tilt, the rays hitting the Earth would have minimal changes, meaning no seasons.
