This can best be explained by the fact that _____. the toxins that cause acid rain leave the factory by way of run off, and then contaminate lakes, ponds and streams. pollutants from a factory can be carried by the wind to far-off locations. most factories have large fans that propel the pollution far away from the factory site. airplanes release acid rain while flying.

The first step of protein synthesis is called transcription. The DNA transcription to mRNA is actually the first step of the protein synthesis. During the transcription step the instructions encoded in the DNA of the genes are transcribed into the nucleotide sequence code of a ribonucleic acid (RNA)....

so your answer is Option (A)

Final answer:

The first step of making a protein from DNA instructions is transcription (option a), where the genetic code of DNA is copied into mRNA. This step is critical for transferring genetic code into a form that can be used to synthesize proteins.

Explanation:

The First Step of Protein Synthesis

The first step of making a protein from DNA instructions is known as transcription. This process involves the transcription of the genetic information in double-stranded deoxyribonucleic acid (DNA) into the single-stranded messenger molecule ribonucleic acid (RNA). It occurs in the nucleus of a cell and involves the creation of messenger RNA (mRNA) from the DNA template. After transcription, mRNA leaves the nucleus and is used in the next phase of protein synthesis, translation, where the mRNA is decoded to synthesize a protein.

Transcription is the critical first step that sets the stage for protein synthesis by allowing the genetic code carried in DNA to be transferred into a form that can be read and used to assemble proteins. Without this essential conversion from DNA to RNA, the process of reading the genetic instructions and constructing proteins cannot begin.

Cartilage is avascular, which is the basic physiological reason behind the prolonged recovery of the injury.  

Cartilage is avascular tissue, which is a contrasting feature of bone tissue. Both the cartilage and bone comprises cells, which discharge an extracellular matrix that produces the composition of the tissue. Cartilage is more flexible in comparison to the bone, however, it also possesses substantial tensile strength.  

The repairing of cartilage is mainly a gradual procedure and may in fact not take place in some of the situations. In comparison to cartilage, the extracellular matrix of bone is mineralized, forming a hard tissue that possesses the tendency of giving support for the body and safeguarding for its essential compositions.  

Answer:

The punnet square

Explanation:

In order to create a punnet square you have to name the or put a representation to the genes, les say it would be C and N, C for colorblind and N for normal:

Father   Mother

                  N           N

   C           CN         CN

   N           NN        NN

So that would be the punnet square, remember that sex comes into consideration because women can´t be colorblind nor carriers of the gene.

Forensic biologists analyze tiny DNA samples using PCR and STR loci analysis, comparing it with criminal DNA databases.

Forensic biologists analyze tiny samples of DNA found at crime scenes through a process involving DNA isolation, sequencing, and analysis. They primarily use polymerase chain reaction (PCR) amplification of short tandem repeat (STR) loci and electrophoresis to determine the length of the PCR-amplified fragment.

One of the main focuses is on mitochondrial DNA sequencing for forensics and comparing the DNA with a database of DNA profiles of known criminals. Forensic biologists play a crucial role in presenting their findings in court hearings, primarily working in crime labs of government agencies.

Answer:

B.  The volume of the liquid should be measured before it is heated.

Explanation:

A student made serious mistake that he did not measure the volume of the liquid before heating.

The scientific experimentation along with care and attention need a proper protocol which a scientist needs to follow to get the results.

The initial hypothesis of the student shows that he wants to know the change in volume, so it is inevitable to calculate the initial volume to know the difference after the completion of experiment.

All other options seem less appropriate than Option B, therefore B is the right answer.

To represent an object moving at a constant speed of 60 mph for 10 hours on a V-T graph, you would draw a perfectly horizontal line.

In a velocity-time (V-T) graph, the horizontal axis represents time (in this case, hours), and the vertical axis represents velocity (in this case, speed in miles per hour, MPH).

When an object is moving at a constant speed, it means that it covers the same amount of distance in the same amount of time consistently. In this scenario, the object is moving at a constant speed of 60 MPH for 10 hours.

The key characteristic of constant speed on a V-T graph is that the velocity remains the same throughout the entire duration of the motion. This is represented by a perfectly horizontal line. The line extends along the velocity axis at the level of 60 MPH, indicating that at any given moment during the 10-hour period, the object's speed remains 60 MPH.

There is no change in velocity (acceleration) over time when an object is moving at a constant speed, hence the horizontal line on the graph. This is a fundamental concept in physics, and it's visually represented on the V-T graph by a straight, horizontal line.

Hi,

There is a relatively new branch of genetics that is called epigenetics, which provides information that how can environmental factors or life style changes can affect the expression of genes without causing changes in the nucleotide sequences of the genes.

You can think about epigenetics as *Tags* which can switch genes on and off just like when we turn a lamp on it produces light and when we turn it off light donot shines.

So, how our life events affect our biology are through several ways.Dr. Rudolph Tanzi is a professor at Harvard university who showed that factors like diet, sleep, behavior and other environmental circumstances can affect our biology by triggering specific genes on and off.

For example: the studies showed that only one week of insufficient sleep can alter the activity of almost 700 genes by triggering different processes like stress, anxiety, mood swings etc.

Similarly, if we have a life style where we feel positive about everything, feel gratitude about blessings then it has shown to positively regulate the activity of genes by causing mind freshness and calmness and more stability of moods.

Similarly, diet can also affect our biology in several ways. For example:  a diet that is excessively rich in carbohydrates can attack our genes and cause disbalance in blood glucose levels. While a diet rich in sulforaphane, resveratrol  and epigallocatechin gallate (green tea) can reverse the damage to DNA and promote a good health.

Answer:

2 sodium

1 carbon

3 oxygen

Explanation:

Na2 = 2 Sodium

C = 1 carbon

O3 = 3 oxygens

Carbon is the basic building block to most cells in the body.

It helps with cellular respiration where your body releases energy stored in glucose and the glucose compound is full of carbon, hydrogen, and oxygen.

Carbon makes up 18% of the human body.

Sugars in the body like glucose hold carbon elements.

Final answer:

Carbon on Earth is predominantly found in its crust and mantle, oceans as bicarbonate ions, and in living and dead organic matter, through the Carbon Cycle. In the human body, carbon makes up about 20% by weight, central to macromolecules and life processes, even though it is relatively rare on Earth.

Explanation:

Where Carbon Is Found on Earth

Carbon is a fundamental element that circulates through the land, ocean, and atmosphere, which is collectively known as the Carbon Cycle. On Earth, most carbon is stored in the crust and mantle, with a significant amount also found in the oceans as bicarbonate ions. Through the process of photosynthesis, plants and algae play a crucial role in converting atmospheric carbon dioxide into organic matter. Aside from its role in living organisms, carbon is also found in carbonate rocks, coal, petroleum, natural gas, and dead organic matter.

Carbon in the Human Body

Carbon is one of the most abundant elements in the human body, making up approximately 20% by weight. It is crucial for the structure of macromolecules and plays an essential role in life processes. Despite being relatively rare on Earth's surface, the human body is efficient at concentrating carbon through the consumption of food, where it assimilates carbon and other elements necessary for survival.

2. A methyl group is a carbon with 3 hydrogen atoms which is an alkyl derived from methane. A methyl group is significant in gene expression. When methyl group are attached to DNA molecules (in a process called DNA methylation),  the process promotes histone complexes hence silences genes.

3. The epigenome is the collection of biochemical compounds and processes that affect the DNA and gene expression without affecting the DNA sequence.  His environment affects the epigenome by indirectly affecting DNA methylation and histone modification. This subsequently affects how a gene is expressed.

4. Based on the aforementioned, it is significant to note that environmental influences on a person begin prenatally (before birth). Genome-wide changes occur immediately after fertilization, therefore life choices, like substance abuse during pregnancy, will affect the character and health of the child postnatally.

Without additional information on the phenotypic expression of the 'B' and 'b' alleles, it is impossible to determine the percentage of gray offspring for the genotypes Bb and BB.

To determine the percentage of offspring that will be gray from parents with genotypes Bb and BB, we can use a Punnett square. The genotype 'B' represents a dominant allele, and the genotype 'b' represents a recessive allele. Since we are not given what the 'B' or 'b' represent in terms of color (gray, black, white, etc.), it's not possible to answer the question about the percentage of gray offspring without additional information. However, the question on Brainly asked for the percentage of offspring that would be gray, and without any knowledge of the phenotypic expression of the genotypes 'B' and 'bb', we cannot determine this from the provided information.

In a typical Punnett square assuming complete dominance, if one parent is heterozygous (Bb) and the other is homozygous dominant (BB), all offspring will appear phenotypically like the dominant parent. This is because they will all have at least one 'B' allele. But without knowing which color 'B' and 'b' stand for, it's impossible to assign colors such as gray to these genotypes.

Answer:

B. Variegation is inherited from the female parent. Only the egg cell contributes cytoplasm with chloroplasts to the embryo.

Explanation:

Inheritance of chloroplast DNA is example of cytoplasmic inheritance. The cytoplasmic DNA is transmitted from egg cell to the embryo. Being regulated by chloroplast DNA, the variegated leaf trait would also exhibit the maternal inheritance and would be passed from egg cell to the embryo.

Example: Presence of green, white or variegates leaves in Mirabilis jalapa follows maternal inheritance

The answer is A. Transformation.

Answer:

a) transformation

Explanation:

The recombinant DNA molecule produced is introduced into a host organism (such as a bacteria) and can then be replicated. This process is known as transformation, in which bacterial cells capture DNA from the external environment.

Host cells copy the vector DNA along with the DNA itself, creating multiple copies of the inserted DNA. Some examples of host cells are the bacteria Escherichia coli and Bacillus subtilis and the yeast Saccharomyces cerevisiae.

C. Mercury is the answer. Mercury and Venus are the only two planets in our solar system that don't have moons

Answer:

The Correct Answer is C.

"Mercury"

Explanation:

Mercury does not have any moon even Mercury also does not have any ring. Mercury is the modest planet in our solar system. It is slightly larger than our Earth's moon. It also the closest planet to the sun. Mercury has barely any atmosphere of its own so Mercury easily can be hit by an asteroid or meteoroid. No moons are orbiting Mercury and Mercury has no ring either.

It enables you to predict responses, I think.

Understanding animal behavior aids in predicting their responses, safeguards humans from potential threats, aids in abiding by animal rights laws, and helps domesticate animals. Historically, this understanding facilitated better hunting strategies and ensured the humane treatment of animals. The ability to recognize innate (genetic) and learned (environmental) behaviors allows us to understand how animal respond to stimuli.

Understanding animal behavior is crucial for several reasons. Primarily, it ensures a harmonious coexistence between humans and animals. For instance, if we understand their behavior, we can predict their responses, potentially exempt us from danger, aid in following humane laws, and foster obedience in domestic animals.

Historically, humans have created deep bonds with animals, like dogs, out of necessity for survival. This relationship required the understanding of their behaviors and migratory patterns. Therefore, the understanding forged better hunting strategies, avoidance of potential threats, and ensured humane treatment.

Our ability to differentiate between innate (genetically driven, independent of environmental influences) and learned behaviors (result of environmental conditioning) is critical. Grasping these behaviors allows us to comprehend the actions of animals in response to certain stimuli. For example, knowing that touching a hot stove would result in pain, is an instance of learned behavior in humans. The same behaviors are observable in animals too.

Answer:

Option (C)

Explanation:

The subduction zones are the features that are created along the convergent plate boundary, where two plates move towards each other. As both the converging plate collides, the denser and heavier plate subducts below the less denser plate and this results in the formation of the subduction zone. As the heavy plate goes down, the pressure on the buried rocks increases and the denser rocks are pulled down deep into the greater depth, where the rocks undergoes partial melting. This zone is marked by the presence of a V-shaped trench that lies just above it.

Thus, the correct answer is option (C).

Final answer:

Marble is a metamorphic rock formed from limestone under high heat and pressure, known for its light color and durability, and used historically in construction and sculpture.

Explanation:

Marble is a type of metamorphic rock that is formed under the surface of the Earth. It originates when limestone is subjected to high heat and pressure, causing it to recrystallize. This process transforms limestone into marble, a harder rock typically characterized by a light color, often white, due to its calcite or dolomite composition. Marble also features colorful markings, contributed by impurities in the original limestone. With its beautiful appearance and durability, marble has been quarried for centuries and used in various applications like buildings and sculptures.

Reefs are formed by calcium carbonate produced by the coral polyps. As a single polyp dies, its soft tissue decays, but the calcium carbonate cup remains.Other polyps build on top of the cup, and when they die, other polyps will build on their cups. Over time, this process creates larger and larger coral reefs.While corals are the chief architects of the reef structure, they are not the only builders. Corallin algae cement various corals together with compounds of calcium, and other organisms such as tube worms andmollusks donate their hard skeletons to the construction.

Some of the interactions that occurs during reef building is called mutualism.

The reef building can be defined as the activities of the organism called coral polyps which involves the secretion of layers of calcium carbonate.

There are many different species interactions that occur during reef building.

One example is mutualism, where two species benefit each other.

For example, the zooxanthellae, a type of algae, provides food to the coral polyps through photosynthesis. In return, the coral provides a protected environment and carbon dioxide for photosynthesis.
