what the difference between saturated and unsaturated
Answer:
Saturated fast are solid at room temperature, unsaturated fats are a liquid at room temperature.
Explanation:
Saturated fast are solid at room temperature and unsaturated fats are a liquid at room temperature. The reason is because in saturated fats there are no double bond between carbon atoms, this gives them their solid structure .
Unsaturated fats have one or more double bonds between carbon atoms, this gives them their liquid form.
One unit of alcohol contains 8 grams of alcohol. calculate the risk of developing liver cancer for someone who consumes 4 units of alcohol a day
The risk of developing liver cancer for someone who consumes 4 units of alcohol a day is twice as high as normal (hepatocellular carcinoma and intrahepatic cholangiocarcinoma).
What does alcohol do to the liver?Alters the production of enzymes, changing the rate of metabolism of the alcohol consumed, causing chronic inflammation, alcoholic hepatitis and cirrhosis. Irritates the mucous membranes of the stomach and esophagus, causing esophagitis, gastritis and diarrhea.
With this information, we can conclude that The risk of developing liver cancer for someone who consumes 4 units of alcohol a day is twice as high as normal (hepatocellular carcinoma and intrahepatic cholangiocarcinoma).

What is competition?Competition is most commonly determined by the interaction of individuals competing for a small quantity of a shared resource.
It can also be characterized more broadly as the indirect or direct interactions of organisms that results in a change in fitness when the organisms share the same resource.
When members of multiple species start competing for the same resource, this is known as interspecific competition.
Woodpeckers and squirrels frequently end up competing for nesting rights in the very same holes and spaces in trees, while African savanna lions and cheetahs compete for the same antelope and gazelle prey.
As in the given case, the water supply is being limited by the humans, it will most likely to cause the competition for the resource. It will lead to shrinkage of deer population along with wolf population.
Thus, the correct option is D.

Look at least two molecules diagrams and think about the features of compounds.
Answer:
---> are isomers of each other
---> have same molecular formula
---> are both hydrocarbons
---> have same number of each kind of atom
Explanation:
Isomers with the same molecular formula. The molecular formula gives a list of the type and quantity of each element in a molecule.
In other words, they are two different molecules with the same type and amount of atoms. The difference is that their structures are different. That being said, the structural formula of the molecules would not be the same. Hydrocarbons are molecules that only consist of carbon (C) and hydrogen (H) atoms.
2. How are the amino acids formed from the codon in Mutation #2 different from those formed from the original codon pattern?
Mutations are caused by the alteration in the nucleotide bases. These altered bases synthesize diverse amino acids relying upon nucleotide base sequences that code for a specific amino acid.
What is Mutation?A mutation may be defined as sudden, stable, and inheritable transformations in the sequence of the genome of an organism.
Mutations can bring a different code for amino acid sequences that results in the synthesis of a particular type of protein.
Before mutation amino acids formed from the codon are specific to their nucleotide bases but mutation causes the alteration in the nucleotide bases which alters the sequence of amino acid and proteins as well.
Therefore, it is well described above.

During which stage of interphase do cells copy their chromosomes?
Answer:
The S phase (Synthesis phase)
DNA replication takes place during the S-phase of interphase, creating two identical sets of DNA. The DNA coils and condenses into units known as chromosomes during the start of mitosis. The two identical sister chromatids that make up each chromosome are joined by a centromere.How does DNA replication work?The biological process of creating two identical copies of DNA from a single original DNA molecule is known as DNA replication.
A double helix of two complementary strands makes up DNA. These strands are split apart in the replication process. The method of semi-conservative replication uses each strand of the original DNA molecule as a template to create its counterpart.
Several enzymes that carry out this process are given below, along with their activities.
____________
DNA Dependent DNA POLYMERASE is a class of enzymes that is responsible for all organisms' DNA replication processes. It accelerates DNA replication in the 5′ to 3′ range.The enzyme known as TOPOISOMERASE is involved in the over- or under-winding of DNA.HELICASE—Using the energy from ATP hydrolysis, which is characterized by the breakdown of hydrogen bonds between annealed nucleotide bases, helicases are frequently employed to separate the strands of a DNA double helix or a self-annealed RNA molecule.DNA GYRASE, a particular kind of topoisomerase, relieves strain caused by DNA helicase's unwinding action.DNA LIGASE- Joins the OKAZAKI FRAGMENT of the lagging strand and re-anneals the semi-conservative strands.PRIMASE - Primase catalyzes the production of a short primer, which is a ssDNA template-specific piece of RNA (or DNA in other species).REPLICATION FORK -(Attachment #1)
_________________
REPLICATION PROCESS -
INITIATION - The beginning of DNA replication takes place at certain locations in the DNA molecule known as ori-sites or regions. Enzymes often recognize these locations and initiate the process. As opposed to C-G base pairs, which produce three hydrogen bonds, A-T base pairs only form two hydrogen bonds, making them easier to strand split. As a result, these sites are typically "AT-rich" (rich in adenine and thymine bases). Following the discovery of the origin, enzymes create a pre-replication complex that unzips the double-stranded DNA. The enzyme topoisomerase is involved in this process.Elongation - The 5'-3' activity of the DNA polymerase enzyme. Now, a new strand was created by DNA polymerase enzymes in the direction of 5′ to 3′ (note: the DNA template is read in 3' to 5' direction). RNA primers were simultaneously created by the primase enzyme and utilized by the polymerase to create new strands of RNA.As DNA polymerase enzyme has 5′ - 3′ direction so two types of strand are form -
LEADING STRAND - A DNA polymerase with high processivity that has the direction 5′ - 3′ (template strand 3′-5′) extends the continuous strand from the primer in the same direction as the replication fork that is expanding. One RNA primer is applied to the leading strand.
LAGGING STRAND - It is the discontinuous strand whose synthesis is going in the opposite direction of the replication fork that is developing. Each primer extends the lagging strand intermittently to create Okazaki fragments. A low processivity DNA polymerase that is different from the replicative polymerase enters to fill the gaps after RNase eliminates the priming RNA pieces. Multiple primers are applied to the lagging strand, and then the Okazaki fragments are joined by the ligase enzyme, filling in the gaps.
TERMINATION - Replication forks meet and end at several locations throughout the chromosome because eukaryotes start DNA replication at various locations; it is unknown how these are controlled. Termination necessitates the halting or blocking of the DNA replication fork's forward motion. When termination occurs at a particular locus, it includes the interaction of two elements: (1) a DNA sequence known as a termination site sequence, and (2) a protein that binds to this region to actually cease DNA replication.

How could the light ray bend as it enters and leaves the water so that you can see the penny at position B? Draw the missing parts of the light ray so the penny is visible at position B.
Water makes the penny visible by bending the light rays towards the normal.
What is refraction of light?Refraction is the bending of light rays as it crosses the boundary of media of different densities.

What is pathogenic invasion?The invasion of a number with the aid of using a pathogen can be aided with the aid of using the manufacturing of bacterial extracellular materials which act in opposition to the host with the aid of using breaking down number one or secondary defenses of the frame. Medical microbiologists talk to those materials as invasins.
