a. Gregory Mendel
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.
Therefore, Option A is correct

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.

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.
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.
➜ Breathing:
The process of obtaining oxygen and releasing carbon dioxide is called breathing.It is a physical process.It takes place in the lungs.It utilises energy from the food.Respiration:

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.

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.

What process moves the water from the roots to the leaves
Answer:
The process is called transpiration stream. in plants transpiration stream is the uninterrupted stream of water and salutes which is taken up by the roots and transported via the xylem to the leaves where it evaporates into the air/apoplast- interface of the substomatal cavity. it is driven by capillary action and in some plants by root pressure.

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).

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).

Answer:
Part 1:
The four astronomical bodies one could choose to represent the 4 labels in the diagram are
A - universe
B - galaxy
C - solar system
D - Mars
The universe contains galaxies and galaxies holds solar systems which have planets like Mars
Part 2: D or a planet like Mars is unlike all their other astronomical bodies it does not have other astronomical bodies within it thus, its different from rest.

Which amino acids do the following codons encode - UUC,
UCU, CUU?
a Phenylalanine, serine, leucine
b Serine, alanine, leucine
C Methionine, serine, leucine
d None of the above
Answer:
A A U C C
A AAA Lysine AUA ACA Threonine
A AAU Asparagine AUU ACU Threonine
A AAC Asparagine AUC ACC Threonine
The codon UUC encodes for the amino acid phenylalanine, the codon UCU encodes serine, and the codon CUU encodes leucine. So the correct answer is (a).
Organic substances known as amino acids have both amino and carboxylic acid functional groups. Proteins are made up of substances called amino acids. Proteins and amino acids are the components of life.
A collection of instructions called the genetic code governs how DNA is converted into proteins. Codons, which are three-nucleotide sequences, are the building blocks of the code. Codons each represent each individual amino acid.
The codons UUC, UCU, and CUU all code for the amino acid phenylalanine. The third nucleotide in the codon determines the amino acid that is encoded. The codons UUA and UUG has different nucleotide from phenylalanine in the third position and thus code for leucine. The codon UCG encode for Serine.
Therefore, option (a) is right.
