Which phase the cell cycle would the cell stop in if you disrupted:_______.
1. the protein DNA polymerase S phase.
2. the depolymerization of the microtubules metaphase.
3. the polymerization of actin cytokenesis.
4. the protein ligase S phase.
5. the chiasmata formation.
Answers
The interphase (G1, S, and G2 phases) precedes meiosis (Meiosis 1 and meiosis 2). Immediately after meiosis, cytokinesis occurs.
1: S phase / 2: Anaphase 1 and 2 / 3: cytokinesis / 4: S phase / 5: Prophase 1.
---------------------------------
The interphase occurs before cell division. It is composed of the G1, S, and G2 stages.
During the S stage occurs the DNI replication process. At this point, also happens the synthesis of histones and other associated proteins. This is the only stage where the DNI molecule is replicated.
Among the enzymes involved in the DNA replication process, two of them are
DNA polymerase III• Responsible for DNA elongation by adding nucleotides to the growing chain, from 3' to 5' extremes.
• It includes only nucleotides that complement the original strand.
• They need to recognize a primer to begin.
DNA polymerase I eliminate ARN primers and substitute them with DNA. DNA ligase seals the gaps that remain after replacing the primers by reestablishing phosphodiester bonds. They also bind the Okasaki fragments during the discontinuous strain synthesis.1. the protein DNA polymerase >>>>>>> S phase.
4. the protein ligase >>>>>>> S phase.
****************************************************
Through Meiosis, a diploid cell (2n) produces four haploid daughter cells (n).
After DNA replication there are two meiotic phases.
The first one is a reductive phase, in which homologous chromosomes separate. In the second phase, the cell suffers a new, not reductive division.During prophase 1 of meiosis, each chromosome carefully pairs with its homologous chromosome.
Crossing-over is the interchange of genetic information between two homologous chromosomes, making the daughter cells genetically different from the original one.
The point where the interchange of genetic information occurs is the chiasma.
5. the chiasma formation >>>>>>> propahase I
****************************************************
Antiparallel microtubules between the separating chromosomes compose the spindle apparatus.
These fibers get elongated during the anaphase, while chromosomes or chromatids migrate to the opposite poles of the cell.
The depolarization of the microtubules drives the chromosomes or chromatids to segregate during the anaphase.
2. the depolymerization of the microtubules >>>>>> anaphase I and II
****************************************************
Actin is a globular protein. Actin filaments are composed of the polymerization of the protein.
Among their many functions, actin polymers are involved in cytokinesis.
The final strangulation of the cytoplasm during the division process occurs through the organization of actin filaments.
Filaments form a ring structure, which progressively narrows its diameter until the complete separation of the two daughter cells.
3. the polymerization of actin >>>>>>> cytokenesis
*******************************
1. the protein DNA polymerase >>>>>>>>> S phase.

Check all that are true of the following scenario.
An archer strings an arrow on a bow and draws the string back. Aiming the bow
upwards at a 45 degree angle, the archer pauses with arms locked into position and
then releases the string. The arrow flies upwards making an arc and then sticks into
the trunk of a tree with an audible thud.
At least four different types of energy are illustrated in this example.
The first energy transformation in the scenario is chemical energy to kinetic.
From the time the archer draws the bow until the thud us heard, entropy increases in
the universe.
The energy of the arrow at the end of the scenario is equal to the energy exerted by the
muscles of the archer.
When the arrow sticks into the tree the original energy has all been used up.
Answers
Statements 1 and 3 are true, while statements 2 and 4 are false.The first energy transformation in the scenario is chemical energy to kinetic. - True.
The archer converts chemical energy stored in their muscles into kinetic energy when they release the string and propel the arrow forward.From the time the archer draws the bow until the thud is heard, entropy increases in the universe. - False. Entropy is a measure of disorder or randomness in a system. In this scenario, the archer's actions do not necessarily lead to an increase in entropy.
The energy of the arrow at the end of the scenario is equal to the energy exerted by the muscles of the archer. - False. Energy is conserved in a closed system, but some energy is lost as heat and sound during the process. Therefore, the energy of the arrow at the end may be less than the energy exerted by the archer's muscles.
When the arrow sticks into the tree, the original energy has all been used up. - False. Energy is not created or destroyed but rather transformed from one form to another. Some of the initial energy from the archer's muscles is transferred to the arrow's kinetic energy, but it is not entirely used up.In summary, statements 1 and 3 are true, while statements 2 and 4 are false.

Answers
The events described involve both mechanical and chemical weathering processes, highlighting the complex nature of how weathering affects geological structures.
The events can be identified as the result of mechanical weathering or chemical weathering as follows:
The minerals in a marble statue react with water to form acids and pores in the structure - This is an example of chemical weathering. The water reacts chemically with the minerals in the marble, causing them to dissolve and form acids. These acids further react with the marble, leading to the formation of pores and overall degradation of the statue's structure.
A piece of rock crumbles after being constantly thrashed by strong waves - This is an example of mechanical weathering. The constant thrashing of strong waves exerts physical force on the rock, causing it to break apart or crumble. This type of weathering occurs due to mechanical forces like abrasion, pressure, or impact that physically break down the rock into smaller pieces.
Industrial runoff forms cracks in a rocky structure in its path - This is a combination of chemical and mechanical weathering. The industrial runoff may contain acidic or corrosive substances that chemically react with the minerals in the rock, leading to their dissolution or weakening. The cracks in the rocky structure may also be a result of the mechanical force exerted by the flowing runoff, causing physical fractures in the rock.
The rocks in a region are streaked orange after being exposed to repeated rains - This is an example of chemical weathering. The repeated rains introduce water into the rocks, which may contain dissolved iron compounds. Over time, these iron compounds oxidize in the presence of water and oxygen, leading to the formation of orange-colored iron oxide minerals, such as rust. The streaking of rocks with orange indicates the chemical transformation of the minerals due to the weathering process.
In summary, the events described involve both mechanical and chemical weathering processes, highlighting the complex nature of how weathering affects geological structures. Mechanical weathering involves physical forces breaking down rocks, while chemical weathering involves chemical reactions leading to the alteration or dissolution of minerals.

Answers
In the experiment, two factors changed throughout the course of the study: the genes of the parental mice and the fur color of the offspring.
The genes of the parental mice: The experiment involved studying the genetic makeup of the parental mice, specifically focusing on the alleles responsible for fur color. The researchers likely examined the genes of the parental mice to determine which alleles they carried and how they could potentially be passed on to their offspring. By studying the genetic composition of the parental mice, the researchers could track the inheritance pattern of the fur color trait.
The fur color of the offspring: The primary objective of the experiment was to investigate how fur color is inherited in mice. To achieve this, the researchers likely observed and recorded the fur color of the offspring produced by the parental mice.
As the experiment progressed and new generations of mice were born, the researchers would have noticed changes in the fur color of the offspring. By comparing the fur color of the offspring to the known genetic makeup of the parental mice, they could analyze the inheritance patterns and determine whether specific alleles were dominant or recessive.

happen to the urine because of it?
Would it have more water or less
water in it? Would it be bright yellow
or pale yellow? Explain your
reasoning.
Answers
If the organism secretes an excess of ADH, urine would be less diluted and showing a bright yellow color due to salts concentration. Options: less water in it and bright yellow.
What is the ADH hormone?
Anti Diuretic Hormone is a molecule that helps kidneys to control water loss through urine.
The ADH, also known as vasopressin hormone, is released by changes in serum osmolarity or blood volume. Its function is to keep homeostasis and make kidneys conserve or keep water by concentrating urine and by reducing its volume. Through these actions, the antidiuretic hormone stimulates water reabsorption, according to the organism's needs.
When the organism secretes too much ADH, the body retains too much water, and blood volume increases.
In these cases, urine would have less water and would be bright yellow because there would be a higher concentration of salts and other waste elements.
