Anterograde Amnesia is when you can no longer a) form new episodic memories after the damage.
What happens in anterograde amnesia?
Anterograde amnesia is a type of memory loss that occurs when you can't form new memories. In the most extreme cases, this means you permanently lose the ability to learn or retain any new information. On its own, this type of memory loss is rare. Anterograde amnesia is often temporary.
What memories are affected by anterograde amnesia?
In most cases of anterograde amnesia, patients lose declarative memory or the recollection of facts, but they retain nondeclarative memory, often called procedural memory.
Does anterograde amnesia affect episodic memory?
Anterograde amnesia is a condition in which a person is unable to create new memories after an amnesia-inducing event. 1 Anterograde amnesia may involve either partial or total inability to remember events. A person with this type of amnesia has intact long-term memories from before the incident.

What does it mean to say that DNA replication is Semiconservative quizlet?
DNA replication is said to be semi-conservative in nature because two copies of the original DNA molecule are produced and each copy basically conserves the information from one half of the original DNA molecule.
Semi-conservative replication basically means that when DNA replication is taking place, the two strands of the nucleotides separate. Both these strands then act as the template for free nucleotides to bind to and create the two identical daughter strands. Therefore, each of these daughter strands have half of the DNA from the original or the parental strand and the half of it is newly-formed DNA.
Semiconservative replication allows the the conservation of the parental characteristics in the offspring.

Sort the following organisms based on their predicted sensitivities to vancomycin. Organisms (6 items) (Drag and drop into the appropriate area below)
Mycoplasma
Clostridium difficile
Viruses
MRSA
E. coli
Fungi
Sensitive: Mycoplasma, Fungi
Resistant: Clostridium difficile, MRSA, E. coli, Viruses
A popular antimicrobial medication for treating severe bacterial infections is vancomycin. It belongs to the class of antibiotics known as glycopeptides and is effective against a variety of gram-positive bacteria, such as staphylococci, streptococci, and enterococci.
Antibiotic sensitivity describes how susceptible a given strain of bacteria is to an antibiotic's effects. A number of variables, like the type of antibiotic, the existence of antibiotic resistance genes, and the particular instance, might affect a particular bacterium's sensitivity to a given antibiotic.
Regarding each of the creatures mentioned in the query:
Mycoplasma: Mycoplasmas are tiny bacteria without a cell wall, making them immune to a wide range of medications, including penicillins and cephalosporins. However, vancomycin is typically thought to be sensitive to mycoplasmas, making it a good alternative for treating infections brought on by these microbes.
Fungi: Eukaryotic organisms that are not bacteria and do not have cell walls are known as fungi. As a result, glycopeptides like vancomycin, which target the bacterial cell wall, are typically ineffective against them. However, some fungi, particularly those that cause infections in people with impaired immune systems, can be vancomycin-susceptible.
Healthcare-associated illnesses, particularly those that take place in hospitals, are frequently linked to the bacterium Clostridium difficile. Many medications, including vancomycin, are known to be ineffective against this bacteria.
Staphylococcus aureus which is methicillin-resistant is known as MRSA. As the name suggests, this bacterium is resistant to penicillin, cephalosporins, and other beta-lactam medicines. Vancomycin resistance is another characteristic of MRSA that makes treatment challenging.
Escherichia coli is a bacteria that is frequently linked to infections of the urinary system, the gastrointestinal tract, and other parts of the body. Although vancomycin is effective against some strains of E. coli, many others are resistant, making it a less desirable alternative for treating infections brought on by this bacterium.
Since viruses lack cell walls and are not bacteria, they are resistant to glycopeptide antibiotics like vancomycin. Antibiotics like vancomycin are rarely used to treat viral infections; instead, antiviral medications are.

Step-by-step explanation:
If all of the A's, B's, C's and D's were different, the number of ways to form a molecule would be calculated as n!. However, given that every molecule is repeat 3 times, we need to reduce the number dividing by 3! for every type of molecule.

What do homologous structures and similarities in embryonic development suggest about the process of evolutionary change?
Answer:
Homologous structures provide evidence for common ancestry, while analogous structures show that similar selective pressures can produce similar adaptations (beneficial features). Similarities and differences among biological molecules (e.g., in the DNA sequence of genes) can be used to determine species' relatedness.
While comparable structures demonstrate that similar selective pressures can result in similar adaptations, homologous structures suggest that they have a common ancestor (beneficial features).
How do homologous structures and embryological similarities help evolution?Since some homologous components may only be detected during the development of an embryo, embryology is crucial to understanding how a species has evolved. For instance, although though the tail does not present in the fully mature organism, all vertebrate embryos, including those of humans, chickens, and fish, have one during the early stages of development.
What makes homology such a crucial concept in evolutionary biology?Existing Structures Serve as the Foundation for New Functions. We learn a crucial lesson about evolution from homologous structures: Primarily, evolution alters pre-existing structures. That is, even when two species perform entirely distinct functions, they frequently use homologous structures to do so.

the second step of replication?
The first step in DNA replication is the unwinding and separation of the double-stranded DNA molecule into single strands, which is facilitated by an enzyme called helicase.
During the second step of DNA replication, the unwound DNA strand serves as a template for the formation of a new complementary strand.
What is DNA replication?The process by which DNA duplicates itself during cell division is known as DNA replication. This is achieved through the process of semi-conservative replication, where the two parent strands serve as templates for the formation of two new daughter strands.
Enzymes called DNA polymerases add nucleotides to the 3' end of the strand, with each new nucleotide being added based on the complementary base pairing rules (A-T, C-G).

as a genetic consultant, what cross would you advise the rancher to conduct to ensure that the allele causing dwarfism is eliminated from hte catle population
As a genetic consultant, I would advise the rancher to conduct a backcross.
In this cross, a homozygous dominant (non-dwarf) individual is crossed with a heterozygous individual (an individual carrying both dominant and recessive alleles for dwarfism). The offspring from this cross will be heterozygous for dwarfism and can be screened for the presence of the recessive allele.
Those individuals without the recessive allele can then be crossed back to the homozygous dominant individual to produce a population of only dominant individuals, eliminating the recessive allele causing dwarfism.
To further ensure that the recessive allele is eliminated, the process can be repeated multiple times to reduce the frequency of the recessive allele in the population.

Answer:
Explanation:
Hemophilia is a sex- linked recessive trait which means that the disease is carried on the sex chromosomes. Females are always represented as, XX. Males are always represented as XY. In this problem you had to cross a carrier female and a normal male. A carrier is a person who carries he disease but doesn't have the disease as it has another dominant allele to mask the recessive allele. Hemophilia is represented as x^r. Down below I have linked the Punnet square to represent the cross.

Why myelinated axons conduct signals faster than Unmyelinated axons?
Answer:
it insulates the axon and assembles voltage-gated sodium channel clusters at discrete nodes along its length.
Explanation:
Myelin can greatly increase the speed of electrical impulses in neurons because it insulates the axon and assembles voltage-gated sodium channel clusters at discrete nodes along its length.
Nerve impulses in myelinated neurons leap over through the nerves rather than pass through it, shortening the path towards the axon terminal, transmit impulses more quickly than unmyelinated neurons.
