Explain how the availability of resources in the environment is linked to exponential growth of a species
Answer: Exponential growth occurs when resources in the environment are abundantly available to a species.
Explanation: When a food source amount drops, so does the survival rate of the predator that eats that specific food source. When a food source grows too abundantly at too fast a rate, predators increase in numbers.

During a large thunderstorm, you hear and feel the thunder. Draw a representation of the sound wave produced. Your model should account for the energy and patterns of the wave.
Answer:
Sound waves are longitudinal waves that travel through a medium like air or water. When we think about sound, we often think about how loud it is (amplitude, or intensity) and its pitch (frequency).
Explanation:
This is why we hear and feel them!
Sound waves are longitudinal waves that travel through a medium like air or water. When we think about sound, we often think about how loud it is (amplitude, or intensity) and its pitch (frequency).
What is Sound waves?A sound wave is the pattern of disruption brought on by the movement of energy moving through a medium as it propagates away from the source of the sound (such as air, water, or any other liquid or solid matter).
Pressure waves are produced when an object vibrates, such as a ringing phone, and these waves are known as sound waves. The surrounding medium's particles are disturbed by the pressure wave, and those particles disturb the particles next to them, and so on.
Like ocean waves, the disturbance's pattern causes outward movement in all directions. Usually in all directions and with decreased intensity as it gets further away from the source, the wave transmits the sound energy through the medium.
Therefore, Sound waves are longitudinal waves that travel through a medium like air or water. When we think about sound, we often think about how loud it is (amplitude, or intensity) and its pitch (frequency).

Y is transcription, and Z is translation
Y is replication, and Z is translation
Y is translation, and Z is transcription
Y is translation, and Z is replication
Answer:
Y is transcription, and Z is translation
Explanation:
DNA to mRNA is the process of transcription (think how DNA and mRNA both have nitrogenous bases, so to get mRNA from DNA you have to transcript-a written or printed version of material originally presented in another medium- it). mRNA to protein is the process of translation (think how mRNA and proteins are made from different building blocks, mRNA being from nitrogenous bases and proteins from amino acids, so it must be translated). Therefore, Y is transcription, and Z is translation.

En un cultivo de células vegetales se introdujo una mutación genética que produjo como consecuencia la incapacidad de estas células para polimerizar todo tipo de moléculas de glucosa. ¿Que consecuencias podrían haber para estas células?
Explanation:
Aun cuando los procesos de replicación del material genético son muy precisos, no son perfectos, por lo que pueden producirse errores que generan cambios. Una mutación es una variación espontánea o inducida del genoma, un cambio permanente y heredable en la secuencia del ADN, en nucleótidos, o bien en la disposición del ADN en el genoma.
Estos cambios o mutaciones se deben a alteraciones de la información genética. Las consecuencias dependen entonces del nivel de afectación: desde cambios en la secuencia nucleotídica, en los genes o los productos génicos, hasta en los tipos celulares involucrados.
Todos los seres vivos cuentan con sistemas de verificación y reparación de los procesos celulares. En el caso de la replicación del ADN existen sistemas de reparación específicos y bien coordinados, pero en ocasiones las lesiones del ADN que escapan a esta verificación serán las causantes de ocasionar mutaciones; por lo tanto, la efectividad de la lesión dependerá tanto de la tasa de división celular, como de la eficiencia de los mecanismos de reparación contra el aumento en las lesiones al ADN. Cuando ambos factores están incrementados, el resultado será una mayor generación de mutaciones o mutagénesis (y carcinogénesis).
Which of these statements describes one way that a nonrenewable energy resource is obtained?
A. Trees are cut down in a forest.
B. Palm trees are planted to produce palm oil.
C. Panels are set up to absorb solar energy.
D. Mountaintops are blown up to mine coal.
In an ecosystem, the statement which describes one way that a nonrenewable energy resource is obtained is that mountaintops are blown up to mine coal.
What is an ecosystem?Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.
Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.

The noble gases in group 18 were some of the last natural elements to be discovered. Why do you think this is so?
Answer:
because they were extremely un-reactive. Being inert, they were difficult to isolate via chemical reactions, thus difficult to distinguish as separate elements
Explanation:
The noble gases of group 18 were the last to be discovered because they are highly unreactive or inert.
Noble gases refer to elements in group 18. These elements are renowned for being inert.
As a result of their inertness and because they are all gases, they are sometimes called "inert gases".
This chemical inertness made it difficult to discover these elements until lately. Many natural elements were discovered because they participate in chemical reactions. Hence, inert gases became the last natural elements to be discovered.

Distinguish between breathing and respiration.
As stated above, breathing is the biological process of inhaling and exhaling of the gases between the cells and the environment. The mechanism of breathing involves various respiratory structures such as the windpipe, lungs and nose. Respiration, on the other hand, is a chemical process that takes place in the cell.

Explanation:
Gregory Mendel is the father of genetics
Gregory Mendel is widely considered to be the father of genetics
Option A is correct
How do we explain?Gregor Mendel was an Austrian monk and botanist who is considered to be the father of genetics. He conducted experiments on pea plants and was able to formulate the laws of inheritance, which are the basic principles of genetics.
Mendel's work was not widely recognized until the early 20th century, but it has since had a profound impact on our understanding of genetics. His work laid the foundation for the study of genetics and has helped to advance our understanding of how traits are passed down from parents to offspring.

Clearly explain the role of mutations in evolution.
Answer:
Mutations are changes in DNA and changes in DNA affect all aspects of an organisms life. The first step to evolution is mutation since it creates new DNA sequences for certain genes. By doing so, is creates new allele. The allele is able to spread through reproduction. All genetic features were initially caused by mutations. Mutation is practically the only way in which a species can have a new variation and so, mutations are the raw material of evolution. Although only hereditary mutations cause evolution, mutations have a large impact on evolution.
