When a volcano erupts, such as the Kilauea volcano in Hawaii, what do you think happens to the surrounding ecosystem? Explain how you think disruptions to the physical and biological components of the ecosystem would affect local populations.
Answer:
the surrounding ecosystem is nearly or completely destroyed this changes the physical and biological components of the system by killing any biological life and reshaping all structures with magma. this will affect the population by killing anything living haunting life for centuries until new life can start to form such as lichens to break down the hardened rocks nutrients into soil for life
The volcanic eruption of Kilauea volcano in Hawaii can have prolonging effects on the water and air quality, and in the livelihoods of the natives living in the surrounding region.
• The volcanic ash has been known to coat the highways, collapse roofs, ground airplanes, and put the natives at threat of developing respiratory ailments.
• The instantaneous influence of the eruption would be the destruction of wildlife and plant species.
• The pyroclastic flows, lava flows, and Kilaeua's discharge of toxic sulfur dioxide can lead to famine and ultimately the loss of livestock and other animals.
Thus, serious consequences would result due to the eruption of Kilauea volcano.

Before attentively reading a text (or a chapter of a text) from beginning to end, pre-reading is the process of scanning the material to identify essential concepts. sometimes known as surveying or previewing.
Pre-reading gives you an overview, which can help you read more quickly and effectively. Examining (and considering) chapter titles, summaries, headings, subheadings, study questions, and conclusions are typical pre-reading activities.
Students can use pre-reading tactics to anticipate what they will read or hear by considering what they already know about a particular topic. Teachers can focus on a book's organization, teach new vocabulary or other concepts, look for the primary idea, and provide students a reason for reading or listening before they even begin to read any material.

The area of north pole has not the part of any country or the north pole does not lie in any country. The main reason of the coldness of the north pole and south pole has that they do not receive any direct sunlight. The best time to visit the north pole has the time of June and July because in this month the ice of the north pole is thinner as compared to other months.

Verdadero o falso mediante el genotipo podemos determinar si existen dominancia en una característica
Answer:
Verdadero
Explanation:
Sabemos que los caracteres dependen de los genes. Y los genes pueden presentarse en forma de alelos dominantes, o alelos recesivos. La expresión de los alelos recesivos son enmascarados o escondidos por el alelo dominante. Es decir, que si ambos alelos se encuentran juntos en un heterocigota, solo el alelo dominante se expresará.
Entonces el alelo dominante expresa la característica que resulta dominante, mientras que el alelo recesivo expresa la característica recesiva.
Genotipo:
Homocigota dominante ----> Expresa caracter dominante (Solo el alelo dominante esta presente)Heterocigota -------------------> Expresa el caracter dominante (Ambos alelos estan presentes, pero el dominante es quien se expresa)Homocigota recesivo --------> Expresa el caracter recesivo (solo alelos recesivos estan presentes)Por ejemplo, si tenemos dos fenotipos rojo y amarillo, y sabemos que el color esta codificado por un gen dialelico llamado M. También supongamos que no sabemos qué alelo expresa qué color. Teniendo solo estos datos, no podemos decir si el rojo es el color dominante o si el amarillo lo es.
Sin embargo, si tenemos los siguientes genotipos acompañando esta información:
MM--> AmarilloMm--> Amarillomm --> RojoRecién ahora podemos deducir que el caracter dominante es el amarillo.

Answer: Plants that always produce the same traits as their parents when they are self pollinated
Mendel used self-pollination in pea plants to grow true-breeding plants for his experiments. When a true-breeding plant self-pollinates, its offspring all have the same traits as the parent. For example, a true-breeding plant with purple flowers always has offspring with purple flowers.

Look at the overall view of the onion root tip. Which phase does it look like most cells are in? Why are most cells in this phase?
Hello. You did not present the image to which this question refers, which makes it impossible for this question to be answered. However, I will try to help you in the best possible way.
I believe you are looking at cells from the tip of the root, in an experiment where the tip of the root of the onion was cut. To redo the tip of the root, the onion cells will undergo mitosis, which is the cell division where a cell originates from two identical cells.
Mitosis has five phases and all of them can be seen in the onion root cells according to the following characteristics:
1. Interphase: it is the moment when the cells increase in size and intensify their metabolic activity. The cells of the onion root will be in this phase when they appear as a completely dark and filled circle.
2. Prophase: The chromosomes condense and become visible and the cell membrane is flawed. In the cells of the onion root, you will be able to see this phase in cells that appear as an irregular circle, with a tangle of lines scattered inside.
3. Metaphase: The chromosomes condense further and connect to the spindle lines that are in the center of the cell. In the onion root cells, you will identify this phase in circles with a tangle of lines that are concentrated in the center of the cells.
4. Anaphase: The centromeres are separated and the sister chromatids migrate to the poles of the cell. You will be able to see this phase in cells that have a concentration of lines at both ends of the cell.
5. Telophase: the chromosomes are decondensed and the cell membrane is formed again while the cell separates into two. You will see this phase with the presentation of two cells.
To improve your understanding, the attached figure below shows how the cell appears in each phase.
How does creationism go against the teachings/indoctrination of natural selection and fitness?

Two ecosystems are compared in terms of population size and species diversity. One ecosystem has a large number of individuals but low species diversity, while the other ecosystem has fewer individuals but greater species diversity due to high mutation rates. Which of the following statements best describes how these two ecosystems would respond to an environmental stress such as drought?
a) The ecosystem with greater diversity is less dependent upon resources and would suffer less from the drought.
b) The ecosystem with greater diversity is more stable and would, therefore, be more likely to withstand the drought.
c) The ecosystem with more individuals is less likely to suffer because it is more productive and, therefore, more stable.
d) The ecosystem with more individuals is more likely to have members that are drought-resistant and will survive and reproduce.
