Biomagnification refers to the process by which toxins or other harmful substances become more concentrated as they move up the food chain. It occurs when a substance enters an ecosystem and is taken up by small organisms, which are then consumed by larger organisms. Each time an organism is consumed, the substance is concentrated in the body of the larger organism, leading to higher and higher levels of the substance in the organisms at the top of the food chain.
For example, imagine a fictional substance called "X" is released into a lake. The "X" is taken up by small aquatic plants, which are then consumed by small fish. The small fish are then consumed by larger fish, and so on, up the food chain. By the time the substance reaches the top predator in the ecosystem, such as an eagle, the concentration of "X" is much higher than it was in the small aquatic plants at the bottom of the food chain.
The sentence "We learned that the solution to pollution is not dilution" relates to biomagnification because it highlights the idea that simply diluting a pollutant by spreading it out over a larger area does not necessarily make it less harmful. Instead, it may just lead to the pollutant being taken up by more organisms, leading to higher levels of the pollutant in the food chain, and potentially more harm to the ecosystem and the organisms living in it.

The pairing of complementary strands of DNA due to hydrogen bonding is called semi-conservative replication.
DNA replicationThe biological process of creating two identical copies of DNA from a single original DNA molecule is known as DNA replication. All living things replicate their DNA, which is the primary mechanism for biological inheritance. This is necessary for:
cell division during tissue development and repair, and it also guarantees that each new cell gets a copy of the DNA.A double helix (two linear strands that run counterclockwise and twist together) of two complementary strands makes up DNA.
These strands are split apart in the replication process. The mechanism of semiconservative replication uses each strand of the original DNA molecule as a template to create its counterpart. The new helix will be made up of an original DNA strand as well as a freshly synthesized strand as a result of semi-conservative replication.

What is an oblique muscle?The oblique muscles are those located on the sides of the abdomen. They are divided into: external oblique muscle, internal oblique muscle and transverse muscle. The external muscle is the largest and most superficial of the three. It lies under the skin of the thoracic and abdominal regions.
Its direct action is flexion, lateral bending and contralateral trunk rotation. The internal oblique muscle is located deep to the external oblique and originates from the inguinal ligament, iliac crest, and thoracolumbar fascia.

Why is the sympathetic nervous system referred to as the fight or flight system?
Answers
As you can see from the diagram below, the human nervous system is divided into two main components, the peripheral nervous system and the central nervous system.
The peripheral nervous system is further divided into two components. The somatic nervous system involves the voluntary movement of skeletal muscle. When you decide to raise your cup of coffee to your mouth, that is the somatic nervous system at work activating the appropriate muscles. The second component of the PNS is the autonomic nervous system, which controls processes that are out of our conscious control.
The autonomic nervous system is further subdivided into the parasympathetic nervous system and the sympathetic nervous system (which you are interested in). In very generalized terms, they have antagonistic effects on each other. The sympathetic nervous system generally activates the body, whereas the parasympathetic nervous system primarily acts to relax the body. This is a simplified view of things, but it is useful to think of it in this way.
The sympathetic division of the autonomic nervous system increases heart rate, inhibits digestion, relaxes bronchi in the the lungs to allow more airflow, causes the release of glucose from the liver, and relaxes the bladder. All of this activates the body, prepares it for a "fight".
In contrast, the parasympathetic division reduces heart rate, constricts bronchi in the lungs, and increases blood flow to the digestive tract. It has been called the "rest and digest" system.
As you can see from the diagram, the nerves of the parasympathetic nervous system come directly from the brainstem and spinal cord. However, with the sympathetic nervous system, there are "ganglia" (groups of cell bodies) outside the spinal cord itself.
Interestingly, the parasympathetic nervous system only uses Acetylcholine (ACh) to exert its effects on organs, but the sympathetic nervous system uses both ACh and norepinephrine (NE) to activate the body.
Its important to remember that the sympathetic and parasympathetic nervous systems are autonomic, meaning we generally have little control over them.

Early in genetic research, it was suggested that the genetic code might be made up of overlapping codons in which the last two bases of one codon make up the first two bases of the next codon, as below:
mRNA codons
overlapping code GGUAUA 1st codon = GGU
2nd codon = GUA
nonoverlapping code GGUAUA 1st codon = GGU
2nd codon = AUA
Supposing it were discovered that, in a life-form from another planet, even a single base pair substitution in the DNA caused three adjacent amino acid changes in the protein coded for. Would you conclude that the code was overlapping or nonoverlapping? Explain your logic.
Answers
The genetic code is called non-overlapping because adjacent codons can not overlap, whereas in this case, the code is overlapping.
What does 'overlapping code' mean?The genetic code does not overlap because the same nucleotide in the sequence cannot be used to encode two different codons.
In genetics, overlapping refers to a feature of the genetic code associated with how this nucleotide code is read.
In conclusion, the genetic code in this case is overlapping.

subject: science
Answers
Answer:
55/8 as a mixed fraction
Explanation:
4 2/8 - 2 5/8 = ?
Four and two-eighths can be represented as a mixed number by multiplying (4x8+2)/8 = 34/8
Two and five-eighths can be represented as a mixed number by multiplying (2x8+5)/8 = 21/8
Then, these two values can be easily added. 34+21 = 55/8
You can plot this on a number line by also representing these mixed fractions as a decimal, and then adding them - you can draw lines to represent the addition process.
Since the number line already represents a tick on every eighth (which is the fraction you would primarily be using), this will make it earlier.
