Answer:
The Factor that most affects drug absorption s the Lipid solubility of the drug
Explanation:
For a drug to accomplish its pharmacological function, it needs to suffer absorption mechanisms.
Most drugs, those that do not act locally, need to be correctly concentrated in their action sites or target sites. The first step is absorption.
This involves the obligated pass through the semipermeable plasmatic membrane to finally get in the blood. In blood, the drug moves, distributes, metabolizes, and the unaltered molecules are excreted.
There are different mechanisms in which drugs can cross the membrane that depends on the drug type. Depending on the effects of these mechanisms, there will be a more or less concentrated drug at the target sites.

A fungus with white spores cross fertilizes a fungus with black spores. If 10% of the progeny bear white spores while 90% of the progeny bear black spores, what must be true?
A.
The trait for spore color is determined by exactly one gene.
B.
The trait for spore color is determined by more than one gene.
C.
The allele for black spores is dominant over that for white spores.
D.
The allele for white spores is dominant over that for black spores.
Answer:
C. The allele for black spores is dominant over that for white spores
Explanation:
Since there are more of an outcome of black spores it would make sense that this trait is dominant.
White spores seem to be recessive in this case too.
It is also suspected that the parents are both heterozygous. They both carry one trait for black and one for white.

Explanation:
How can genetic mutations increase the variation in a population over time?
Answer:
The flow of individuals in and out of a population introduces new alleles and increases genetic variation within that population. Mutations are changes to an organism's DNA that create diversity within a population by introducing new alleles.
Explanation:
Explain how breast-cancer genes are still present in the population, despite cancer-related surgeries and deaths.
Answer:
the correct answer would be - inheritance.
Explanation:
BRC1 is one of the genes that cause breast cancer which is thought to be inherited from the parents and even surgery can remove it from the person or it removed with the death of the person but genes already passed on next generation.
Surgery can not remove the gene but the tumor only and can reappear again. It is impossible to remove the complete gene from the population.
Read the following scenario:
John Doe walks into the bank to deposit his weekly paycheck. While there, one of his hairs falls off the back of his shirt and onto the floor. After depositing the money, he leaves and returns to work. About fifteen minutes later, the bank is robbed at gunpoint by a masked man who is about the same height and build as John Doe. The bank manager is asked to provide a listing of all customers who visited the bank in the past week. The plan to carry out the investigation included searching the crime scene for evidence. Upon doing so, one of the investigators finds the hair belonging to John Doe and tags it as evidence.
Answer the following questions:
Provide at least 3 reasons the hair evidence alone can't be used to pinpoint John Doe in the robbery.
What other evidence in the investigation could have been collected in the attempt to identify the bank robber? the perpetrator.
Explain why hair evidence is generally considered "class" evidence.
Answer:
Hair evidence is considered "class" evidence because the hair can be connected to a certain group.
Explanation:
The hair evidence alone can't be used to pinpoint John Doe in the robbery because he also came to deposit his weekly paycheck so may be the hair drop at that time in the bank. The other reason is that may be the hair has been dropped by the real thieves in order to be caught the John Doe in the crime. Hair evidence is considered "class" evidence because the hair can be connected to a certain group.

What are estuaries?
An estuary is a body of water where a freshwater river or stream meets the ocean. The mixing of these two bodies of water creates a unique environment that supports a diverse range of plant and animal life. Estuaries are important for many different species of fish and shellfish, as well as for waterfowl and other migratory birds.
They also serve as important breeding and feeding grounds for many species. Human activities such as agriculture, urbanization, and pollution can have a negative impact on estuaries and the wildlife that depends on them.

Chromosomal rearrangements are considered large-scale mutations. Point mutations are considered small-scale mutations, and are of two general types. The first is a single nucleotide-pair substitution. What occurs here?
Answer:
Please find what occurs in the single nucleotide-pair substitution below
Explanation:
Single nucleotide-pair substitution is a type of point mutation as stated in this question. Point mutation is when one nucleotide base (single) is affected in the sequence. In this single nucleotide-pair substitution, ONE nucleotide base is substituted by another base.
For example, in a DNA sequence that reads: TAA GTC GGG, a mutated sequence affected by single nucleotide-pair substitution will read as follows: TAA GTC TGG. Note that in the last codon (GGG), a single nucleotide G has been replaced by another nucleotide T. Therefore, single nucleotide-pair substitution is said to have occur.

As one moves from left to right across the periodic table, what trend are evident?
A.) Atomic radius increases moving left to right
B.) Nonmetallic character increases moving left to right
C.) Electron affinity increases across the periodic table
D.) Elements change from solids to liquids and then gases.
E.) Most reactive elements on left and least reactive in n the right.
Answer:
C
Explanation:
Moving from left to right across a period, atoms become smaller as the forces of attraction become stronger. This causes the electron to move closer to the nucleus, thus increasing the electron affinity from left to right across a period. Electron affinity increases from left to right within a period.

4. What must be true to have offspring with red eyes?
5. What must be true to have offspring with red eyes and white fur?
Answer: Genetics
Explanation: This may sound a little strange, but in order to have animals with certain traits, they must be born with or have in the blood line to have said traits. Even then the traits exhibited may not be hereditary. There is a 50% chance that the genetics that you want the offspring to have, may not occur. When a child is made, this means that the parents donate chromosomes from both sides to give the child some of their looks. This could mean disease, eye color, hair thickness.

Use Sammi's model as an example to explain why cells are the building blocks for human bodies.
Answer:
Sammi's model uses common materials to represent the different parts of the circulatory system. These different parts represent the heart, blood vessels, capillaries, and digestive tract. The model shows that blood is pumped by the heart through the blood vessels, then through the capillaries located in the digestive tract, and back into the blood vessels. Sammi's model also shows that clear water becomes green after traveling through the cardboard tube, which represents the digestive tract and capillaries. This is because the particles lined in the cardboard tube are absorbed into the water. This is much like the circulatory system because blood travels through the capillaries and absorbs the nutrients stored in the villi, which are represented by the corrugated inside of the cardboard tube, that absorb nutrients from the digestive tract. The blood then travels back into the blood vessels to deliver this nutrients throughout the rest of the body, which is vital for the function of all organs in the body.
This model supports that cells are the building blocks for human bodies because it shows how each part of the digestive and circulatory systems work to move cells around in the body in order to provide nutrients and required substances to keep the body functioning properly. If the digestive and circulatory systems were not functioning, the body could not function either because the nutrients and cells that are transported by these systems are required for life of the human body.
Explanation:
This is my own personal answer, so if there are any mistakes please feel free to correct me. You may want to paraphrase or change parts of this answer. I hope this helps! Have a wonderful day! :)
Cells are the building blocks for human bodies because cells have different parts and each performs specific functions.
A cell refers to the smallest, basic unit of life. The model uses common materials to represent the different parts of the circulatory system.
From the model, it can be seen that some of the parts that are represented include the heart, blood vessels, capillaries, and digestive tract. This illustrates that for blood to be pumped into the body, different organs have specific roles to play just like the cells have different functions to play in the human body.

What structures are responsible for the movement of chromosomes to the center of the cell in metaphase and their separation in anaphase
Answer:
The structures that are responsible for the movement of chromosomes to the center of the cell in metaphase is the spindle fibers, the cell attaches the centromeres to the spindle fibers to pull the sister chromatids to the center
In anaphase the sister chromatids are separated at the centromere and are pulled to the opposite poles of the cell by the spindle fibers
Explanation:
The structures responsible for the movement of chromosomes to the center of the cell in metaphase and their separation in anaphase would be the spindle fibers.
The spindle fibers are formed from microtubules near the two poles of a dividing cell. Spindle formation starts from prophase and continues to grow and extend towards the centromere of chromosomes.
At metaphase, the spindle fibers would have successfully attached to each chromosome at the kinetochore of their centromeres. Once this is done, the spindle fibers start shortening, pulling sister chromatids apart towards opposing poles in the process.
The shortening of the spindle fibers serves as the vehicle that transports sister chromatids to the poles.
