Answer:

The correct order of protein production is:

c) 1,2,4,3

Ribosome: Protein synthesis begins in the ribosomes, which are located either in the cytoplasm or attached to the endoplasmic reticulum.

Endoplasmic Reticulum: After the initial stages of protein synthesis in the ribosomes, the newly synthesized protein is transported into the endoplasmic reticulum (ER) for further processing and modification.

Golgi Apparatus: The proteins synthesized in the ER undergo further processing and modifications in the Golgi apparatus. This includes sorting, packaging, and modifying the proteins to their final functional forms.

Secretory Vesicles: Once the proteins are properly processed and modified in the Golgi apparatus, they are packaged into secretory vesicles. These vesicles transport the proteins to their destination, such as the plasma membrane for secretion outside the cell.

Therefore, the correct order is 1, 2, 4, 3.

Answer:

The correct order of protein production is ribosome, endoplasmic reticulum, Golgi apparatus, and secretory vesicles. So the correct answer would be c) 1,2,4,3.

Many proteins destined for the endoplasmic reticulum, the Golgi apparatus, lysosomes, the plasma membrane, and secretion from the cell are synthesized on ribosomes that are bound to the membrane of the endoplasmic reticulum. The Golgi apparatus then distributes these proteins and lipids that it receives from the ER.

There are different types of interactions among species, like 1) coevolution and 2) parasitism.

Coevolution → relationship between two species that interact and adapt to each other. Occurs a reciprocal genetic change due to selective pressures that each species imposes on the other.

Parasitism → interaction between species in which one of them is beneficiated, while the other suffers a consequence, reducing its fitness. These interactions are mainly about nutrition.

In this case, the population of moths you're referring to has a number of variations. Here they are:

1. Wing Color Variation: The moths have two phenotypic variations for wing color, brown and white. This is a clear physical trait that can change based on the genetic makeup of the moth.

2. Survival Variation: Out of every 100 eggs laid, only about 10 moths survive to adulthood. This could imply a variation in the fitness or adaptability of the offspring, where only the most fit or adaptable (in terms of avoiding predators, finding food, or handling environmental conditions, for example) survive.

3. Seasonal Environment Variation: The environment where the moths live changes with the seasons. In winter, the trees lose their leaves, which may affect the camouflage ability of the moths depending on their wing color. This is a temporal variation in the environment, which can potentially influence the survival rates of the different moth variations.

4. Predation Variation: The predators of the moths are birds, which hunt for the moths as they rest on the dark tree bark. The level of predation can vary based on factors like the bird population size, hunting efficiency, and the visibility of the moths.

Each of these variations plays a role in the survival and reproduction of the moths and could lead to evolutionary changes in the population over time, especially if certain traits (like wing color) increase the moths' survival and reproductive success.

The process of respiration can be divided into the cellular view to the general (cellular respiration to external respiration). Going from the cellular till the external we have:

1- Cellular respiration

Is the aerobic process by which living cells break down glucose molecules to form energy in the from of ATP, that can be divided in three stages, these are: glycolisis (break of glucose into pyruvate), Citric Acid Cycle (Krebs Cycle), and electron transport chain. In this respiration the cell machinery is responsible for from glucose and oxygen form water and carbon dioxide. All the process is intracellular.

2- Internal respiration

The internal respiration is the process of the exchange of gases between the cells and the tissues (internal environment of the body) by the blood vessels and the circulation od red blood cells that carry these gases (oxygen and carbon dioxide). The path of this process is: nose/mouth, pharynx, larynx, and trachea will have the cells oxigenated, the trachea branches and the bronchi will lead to the lungs when the gases exchanges in the tissue will happen. The red blood cells will do the local capture of the gases and the circulatory system will make those cells go to all the tissues in the body.

3- External respiration

The external respiration is the exchange of gases with the external environment. That process occurs in the lungs where the oxygen diffuses into the blood and carbon dioxide into the alveolar air. The internal and external respiration work together in the overall respiratory process, but one happen in the tissues and the other between external environments.

4- How they work together?

The three process are essential for breathing, that's because they work into different levels of tissue and systemic organization. The cellular is the one in the cells that provide the biochemical reactions necessary to the synthesis and conversion of molecules, being the metabolic basis for the respiration to take place, the internal respiration is responsible to distribute the gases into the tissues to make the cellular step possible, while the external respiration makes possible the exchange outside the tissues levels and makes possible to balance the distribution and concentration of the gases in the body.

Mistletoe is a type of parasitic plant that belongs to the family Santalaceae. One positive effect of mistletoes on ecosystems is their role in providing food and habitat for various bird species.

Mistletoes are parasitic plants that grow on the branches of other trees. While they can have negative effects on the host tree, such as reduced growth and weakened structure, they also bring certain benefits to the ecosystems where they grow. One of these benefits is their significance as a food source for birds. Mistletoe berries contain a sticky pulp that is rich in sugars, providing a valuable food resource for many bird species, especially during the winter months when other food sources may be scarce. Birds play an essential role in seed dispersal for mistletoes, as they consume the berries and excrete the undigested seeds onto the branches of other trees, contributing to the dispersal and establishment of mistletoe plants in new locations.

Moreover, mistletoes can also provide nesting sites and shelter for birds. The dense foliage of mistletoe plants offers protection and cover for birds, particularly smaller species, helping to create suitable habitat conditions within the forest ecosystem. By providing food resources and nesting opportunities, mistletoes contribute to the overall biodiversity and ecological balance of the ecosystems in which they grow.

In a nuclear fission reaction, the nucleus of an atom is split into two or more smaller nuclei, releasing a large amount of energy.

This process occurs when a heavy nucleus, such as uranium-235 or plutonium-239, absorbs a neutron, becoming unstable and undergoing fission.

Let's take the example of the nuclear equation for the fission of uranium-235:

U-235 + n-1 → Ba-141 + Kr-92 + 3n-1 + energy

In this equation, the reactants are uranium-235 (U-235) and a neutron (n-1), while the products are barium-141 (Ba-141), krypton-92 (Kr-92), three neutrons (n-1), and a significant amount of energy.

The reaction starts with the absorption of a neutron by the uranium-235 nucleus, which causes it to become highly unstable. The nucleus then splits into two smaller nuclei, in this case, barium-141 and krypton-92. Additionally, three neutrons are released during the process. The energy released is a result of the conversion of a small fraction of the mass of the uranium nucleus into energy, according to Einstein's famous equation, E=mc².

This nuclear fission reaction is self-sustaining and can produce a chain reaction if additional neutrons are available to cause the fission of more uranium-235 nuclei. The release of a large amount of energy makes nuclear fission reactions useful in various applications, such as power generation in nuclear reactors or the detonation of nuclear weapons.

The expected ratio of DNA molecules following two generations in a medium containing 14N is 50% 15N15N DNA: 50% 15N14N DNA.

The experiment by Meselson and Stahl proved the mode of DNA replication. Starting with bacterial cells grown in 15N nitrogen, the ratios of DNA molecules to be expected following two generations in a medium containing 14N are 50% 15N15N DNA: 50% 15N14N DNA. In the experiment of Meselson and Stahl, they took E.coli bacteria and grew them in a 15N medium which means that the bacteria cells incorporated 15N into their DNA.

After that, they shifted the bacteria into a 14N medium and allowed it to grow for a generation. In the first generation, the DNA of the bacteria was centrifuged and it was found that all of the DNA was intermediate in density because they contained both 15N and 14N in equal amounts which disproved the conservative mode of DNA replication. In the second generation, the DNA was again centrifuged and it was found that the DNA was present in two forms.

One was intermediate and the other was light in density. The intermediate band was found because half of the DNA was synthesized in a medium containing 15N and the other half was synthesized in a medium containing 14N, making the two strands in a DNA molecule different. This experiment by Meselson and Stahl proved that the semi-conservative mode of DNA replication is the correct method of DNA replication.
