What is the most important organism on the food web?

Answer:

The first principle you need to understand about geologic time is that the laws of nature are always the same. This means that the laws describing how things work are the same today as they were billions of years ago. For example, water freezes at 0°C. This law has always been true and always will be true. Knowing the natural laws helps you think about Earth’s past, because it gives you clues about how things happened very long ago. It means that we can use present-day processes to interpret the past. Imagine you find fossils of sea animals in a rock. The laws of nature say that sea animals must live in the sea. That law has never changed, so the rock must have formed near the sea. The rock may be millions of years old, but the fossils in it are a clue for us today about how it formed.

Now imagine that you find that same rock with fossils of a sea animal in a place that is very dry and nowhere near the sea. How could that be? Remember that the laws of nature never change. Therefore, the fossil means that the rock definitely formed by the sea. This tells you that even though the area is now dry, it must have once been underwater. Clues like this have helped scientists learn that Earth’s surface features have changed many times. Spots that were once covered by warm seas may now be cool and dry. Places that now have tall mountains may have once been low, flat ground. These kinds of changes take place over many millions of years, but they are still slowly going on today. The place where you live right now may look very different in the far future.

The first principle you need to understand about geologic time is that the laws of nature are always the same.

Water, for instance, freezes at 0°C. This rule has held and will continue to hold forever.

Understanding natural principles facilitate historical thinking because it provides hints about how things were very long ago. It implies that we can interpret the past using current methods.

The rock must have formed close to the sea because this law has never changed.

Therefore, The first principle you need to understand about geologic time is that the laws of nature are always the same.

A colorist is a film industry professional who creates a visual color story for a production. In the post-production stage of the film making process, a colorist can use color editing software to add the desired hues, tones and color palates to an edited film.

They also work closely with editors to ensure they use similar software. Colorists have specific software package requirements because most colorists use Adobe products, specifically After Effects and Premiere Pro.

A Colorist is responsible for designing the color scheme of a film in order to achieve a specific mood or visual style. Colorists work closely with a film's director and director of photography to determine what color palette will best serve the story.

Examples of greenhouses gases are water vapor, carbon dioxide. methane, nitrous oxide and ozone (O3). Lightning produces ozone as does UV light at high altitudes, methane is produced biologically and in volcanoes (but doesn’t last long in the atmosphere). Carbon Dioxide is also produced biologically and in volcanoes. Water vapour is most from ocean evaporation, which is bad news if the Earth gets hotter because that leads to more Water vapour.

Question:

Chromosomes are distributed randomly during anaphase I. What are the possible chromosome combinations in the two daughter cells? (Use the following abbreviations for the chromosomes. Dark green -> DG; Light  green -> LG; Dark purple-> DP, Light purple -> LP)

How does the random lining up of the homologous chromosome in Metaphase 1 contribute to Genetic Variation?

Answer:

Possible chromosome combinations:

The random arrangement of tetrads is different in every cell going through the meiosis process. Any chromosome of the homologous pair might face any of the poles and then migrate to it. 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 different and depends on the chromosomes that form that cell.

Explanation:  

1) During meiosis, organisms can produce at least four different  gametes. Anaphase occurs after the prophase where crossing-over has occurred. During anaphase 1, the homologous chromosomes separate, migrating to different poles.

The possible chromosome combinations in the two daughter cells of the exposed example are

2) Crossing-over between homologous chromosomes (prophase 1), the random lining of homologous chromosomes (metaphase 1), and random fertilization are the mechanisms involved in genetic variation.

During metaphase I, homologous pairs together migrate to the equatorial plane, where 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. Any chromosome of the homologous pair might face any of the poles and then migrate to it. 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.

Possible chromosome combinations:

The random arrangement of tetrads is different in every cell browsing the meiosis process. Any chromosome of the homologous pair might face any of the poles and then migrate to it.

Each of the chromosomes has two possibilities for orientation at the plane. When the new haploid cells are formed, the amount of variations in each cell is different and depends on the chromosomes that form that cell.

During meiosis, organisms can produce a minimum of four different gametes. Anaphase occurs after the prophase where crossing-over has occurred. During anaphase 1, the homologous chromosomes separate, migrating to different poles.

The possible chromosome combinations within the two daughter cells of the exposed example are-

Crossing-over between homologous chromosomes (prophase 1), the random lining of homologous chromosomes (metaphase 1), and random fertilization are the mechanisms involved in genetic variation.

During metaphase I, homologous pairs together migrate to the equatorial plane, where they randomly aline with their kinetochores facing opposite poles.

The random arrangement of tetrads is different in every cell browsing the meiosis process. There is no equal alinement between the two cells.

When tetrads aline within the equatorial plane, there's no predetermined order for every one of the homologous chromosomes of every tetrad to face one among the poles then migrate to it while separating.

Any chromosome of the homologous pair might face any of the poles then migrate thereto. Each of the chromosomes has two possibilities for orientation at the plane.

When the new haploid cells are formed, the amount of variations in each cell is additionally different and depends on the chromosomes that form that cell.

This random order within the equatorial plane is what introduces variation into the gametes. It is almost impossible that two gametes resulting from meiosis will get an equivalent genetic charge.

Therefore,the combinations of two daughter cells LG,LP + DG,DP and LG,DP + DG,LP.

B. It shows offspring that have the same genes as the parent.

C. It shows asexual reproduction.

Explanation:

Hydra reproduces by budding​ which is kind of asexual reproduction. In budding, a small bud appears on the body of that organism and grow in size with the passage of time and finally detached from the parent body. so no fusion of gametes occurs so no chance of genetic variation. The offspring have the same genes as the parent because it forms from one parent.

Answer: Parasitism, Predator-Prey, Competition

Explanation:

The symbiotic relationship is the relationship in which two distinct species are associated with each other. In the symbiotic relation the species may get harm or benefit of association. Parasitism can be defined as the symbiotic relationship in which one species get harmed and other one receives the benefit. For example, malarial parasite plasmodium derives the nourishment from the host body (human). Predator-prey relationship is also harmful as the predator kills the prey to obtain it as food. Competition is harmful in the sense two or more organisms of the same or different species compete for the same resource, the most dominant receives the resource the inferior organism is either killed or harmed in the fight for resources.

Fragments of rock or lava that are sent into the air in a volcanic explosion are called tephra.

Explanation:

The volcanoes come in different shapes and sizes, and with them come different types of eruptions as well. Some volcanoes have explosive eruptions, some mainly release ashes and gasses, while some erupt with lava flows. The volcanoes that have explosive eruptions release a lot of pyroclastic material often propelled high and wide around them.

Part of the pyroclastic material that is released is the tephra. Tephra is basically represented by fragments of very hot rock and lava that are shoot into the air during a volcanic eruption. The tephra is extremely dangerous, as it can be shoot out over a distance of several km, and being very heavy, very hot, and moving at very high speed, when it hits something it manages to destroy it or cause enormous damage, and if it is a living organism that is hot it will mean the end of it for sure.

Guard cells close openings in the leaves slowing down water loss.

Answer:

True

Explanation:

Stomata are pores in the leaf that allow gas exchange where water vapor leaves the plant and carbon dioxide enters. Special cells called guard cells control each pore's opening or closing. When stomata are open, transpiration rates increase; when they are closed, transpiration rates decrease. So when it is opened the water vapor depletes quicker but when its closed it slows down the process of depletion.
