Answer:
strike-slip is when the blocks have mostly moved horizontally, normal is when a dip-slip fault in which the block above the fault has moved downward relative to the block below, and thrust is when the hanging wall moves up relative to the footwall.
There are three faults. Normal faults originate from the divergent boundary. Reverse faults originate from the convergent boundary. Strike-slip fault originate from transforming boundary.
What are the three types of fault?We can differenciate three types of faults,
Normal fault ⇒ originate from divergent movementReverse fault ⇒ originate from convergent movementStricke-slip fault ⇒ originate from transforming movementWhat are the boundary types?I. Divergent:
This boundary occurs when two plates separate and molten material rises from the mantle creating a new crust.
The hot material creates a new seabed between the separating plates, expanding the sea bottom.
II. Convergent.
Collision area between two plates. Two oceanic plates might collide, or one oceanic plate with a continental one.
In this last case, the oceanic crust sinks under the continental plate, and magma rises to the surface by crevices.
The thicker and older plate subduces under the other plate.
III. Transforming.
The plates slide laterally with each other, and they are usually called faults.
It is associated, in general, with the oceanic ridge, although it might also occur in the continental plate.
No rocky material is either destroyed or formed.
When the plates move and produce a displacement of one transforming limits from side to side, earthquakes occur.
The movement breaks the crust and originates pronounced fractures.

Graded for correctness: In humans, the ability to digest lactose beyond childhood is determined by a single gene on chromosome 1. L denotes the allele that gives the ability to digest lactose and l denotes the inability to digest lactose. On chromosome 3 is the gene for widows peak. A denotes the allele for no widows peak and a denotes a widows peak. A woman volunteers to be a participant in a genetic research study. Her genotype is LlAa. A doctor harvests a single egg from her body. The genotype of her egg is LA. How did her chromosomes line up at the metaphase plate during meiosis
Answer:
Metaphase I:
Homologous chromosomes are placed in the equatorial planeChromosomes carrying the dominant alleles, L and A, face one of the polesThe homologous chromosomes, carrying the recessive alleles, l and a, face the opposite pole.Metaphase II:
Chromosomes carrying the dominant alleles, L and A, are placed in the equatorial planeOne of the chromatid sisters of each chromosome faces one of the polesThe other chromatid sisters of each chromosome face the opposite pole.You will find the image in the attached files.
Explanation:
During metaphase I, homologous pairs migrate to the equatorial plane. They randomly aline with their kinetochores facing opposite poles. The random arrangement of tetrads is different in every cell going through the meiosis process. There is no equal alinement between two cells. When tetrads aline in the equatorial plane, there is no predetermined order for each of the homologous chromosomes of each tetrad to face one of the poles and then migrate to it while separating. Each of the chromosomes has two possibilities for orientation at the plane. When the new haploid cells are formed, the number of variations in each cell is also different and depends on the chromosomes that form that cell. This random order in the equatorial plane is what introduces variation into the gametes. It is almost impossible that two gametes resulting from meiosis will get the same genetic charge.
During metaphase II, fibers of the spindle apparatus take chromosomes toward the equatorial cell plane, where they line up. Sister chromatids are holden together until they reach the Anaphase, during which specialized enzymes break the bonds between chromatids and separate them. Each chromatid migrates to one of the poles. In telophase, the new chromosomes are already in the corresponding poles, and the nuclear membrane forms again. Finally, cytokinesis occurs.
In this example, we will assume no crossing-over in the prophase. I will propose the two metaphase stages.
Metaphase I: Pole 1
Chromosome 1 ---------L---- -----------A--------- Chromosome 3
----------L---- -----------A---------
Equatorial plane.....................................................................................................
Chromosome 1 ---------l---- -----------a--------- Chromosome 3
---------l---- -----------a---------
Pole 2
In this scheme of Metaphase I, homologous chromosomes are already aligned in the equatorial plane. Each homologous chromosome is facing a pole. So, in the superior part of the scheme, we have chromosomes 1 and 2 carrying the dominant alleles L and A. Both chromosomes are facing pole 1. Then, we can recognize the equatorial plane, and on the other side, we find the homologous chromosomes 1 and 2, facing pole 2, and carrying the recessive alleles, l and a.
During anaphase I, homologous chromosomes will separate and migrate to different poles. In this example, we are interested in chromosomes carrying the dominant alleles that migrate to pole 1. LL and AA.
Metaphase II: Pole 1
Chromatid 1 ---------L---- -----------A-------- Chromatid 3
Equatorial plane.....................................................................................................
Chromatid 1 ----------L---- -----------A--------- Chromatid 3
Pole 2
During metaphase II, each chromatid sister carrying the dominant alleles faces a different pole. During anaphase II they separate and migrate again.
The total result of meiosis in this particular cell is the formation of 4 haploid cells -gametes-: LA, LA, la, la

Match each idea about evolution to the person or group where it originated from the drop down menu
Hello. You did not present the ideas about evolution to which the question refers, which makes it impossible for your question to be answered. However, I will try to help you in the best possible way, showing you the main ideas about evolution and the people who originated them.
According to Jean-Baptiste organisms evolve as a way of seeking perfection.
According to the ancient Greeks and Romans, all living things are in a constant process of change. This change causes evolution and when a living being evolves it causes the evolution of another living being, since everyone is connected and related.
According to Darwin, evolution occurs over time and through an ancestor. For him All living beings have a common ancestor, which evolved over time and generated new species. Darvin also believes that any characteristic acquired by evolution could be passed on to the descendants.
According to Malthus, living beings generate a number of descendants disproportionate to the resources necessary for their survival and this causes evolution.

Question 1. What change led to an increase in the number of light-colored moths within the population?
1. More mutations
2. Decreased pollution
3. More dark colored trees
4. Fewer humans
Question 2. Claim: Individuals in a population have genetic variations that can be passed on to their offspring. Refer back to the rabbits in the desert from the natural selection activity we did in class. How could an organism's traits influence the survival rate of the population?
Answer: 1. 1. More mutations. 2. According to Charles Darwin's theory of evolution by natural selection, organisms that possess heritable traits that enable them to better adapt to their environment compared with other members of their species will be more likely to survive, reproduce, and pass more of their genes on to the next generation.

5 5. Normally, the temperature inside the scrotum is slightly lower than normal body temperature. What do you predict would happen if the temperature inside the scrotum were a few degrees higher than normal body temperature instead? A. Sperm would not be able to travel through the vas deferens. B. Sperm would be stored in the epididymis rather than in the testes. c. Sperm would not be able to develop properly. D. The rate of sperm production would increase,
Answer:
C. Sperm would not be able to develop properly.
Explanation:
There is an optimum temperature where sperm production is at its best. An increase or decrease in temperature may affect the quality and quantity of the sperm.
If the temperature inside the "sc-rotum" raises by few degree than normal body temperature, than the "sp-erm" would not be able to develop properly.
What is the function of "sc-rotum"?A pouch, which is suspended from the groin, and comprising the "tes-tes" and some of the male "s-ex" accessory ducts is known as the "sc-rotum". The prime function of the "sc-rotum" is to maintain the temperature essential for the process of "sper-matogenesis", that is, by situating the testes external of the body cavity.
Within the human "sc-rotum", the temperature is 3.1 degree C lesser than the usual temperature of the body. In case, if the temperature elevates of the "sc-rotum", the degeneration of the germinal epithelium will take place, which will eventually result in sterility. Therefore, for the production of sperms within the testes, a lower temperature is needed, otherwise the development of the "sp-erm" will not take place appropriately.
Thus, the correct answer is option C.

What changes occur in taste receptors when the membrane is depolarized during receptor potential A. Voltage-gated Ca2 channels open, triggering the release of neurotransmitter. B. Voltage-gated Cl- channels open, triggering the release of neurotransmitter. C. Voltage-gated Ca2 channels open, inhibiting the release of neurotransmitter. D. Voltage-gated Cl- channels open, inhibiting the release of neurotransmitter.
Answer:
A. Voltage-gated Ca² channels open, triggering the release of neurotransmitters.
Explanation:
For taste mechanisms to function properly, it is necessary the activation of taste receptors.
Through the activation of taste receptors, transduction cascades occur, involving ion channels that are located in the apical or lateral membranes. There occurs a subsequent release of chemical neurotransmitters that send signals to the control centers.
Salty and sweet flavors produce the membrane depolarization that results in Ca+ ions´ entrance to the cell. Ca+ initiates the release of neurotransmitters. Afferent gustative neurons receive the message and send it to the control center, the encephalon. After that, gustative cells go back to the initial state, repolarizing.
