Shown below are 4 stages (A,B,C,D) (not in sequence) of a certain kind of cell division.
The diagram below shows a cell undergoing mitosis (cell division). The correct order of the stages is B, C, D and A.
Mitosis is a type of cell division in which a parental cell divides to produce two genetically identical daughter cells.
In this case, an animal cell is undergone mitosis because the cell exhibits centrioles (only found in animal cells) and lacks cell walls (only present in plant cells).
The stages of mitosis include prophase, prometaphase, metaphase, anaphase, and telophase.

in an El nino event, surface temperatures of the pacific oceans are above average for at least a year. what effect, if any, would warmer temperatures have on the growth of a kelp forest ecosystem on the california coast?
El Niño is a phenomenon that impedes warm water to move westward and upwellings events. The kelp forest ecosystem is negatively affected by the rise in water temperature, lack of nutrients, and consequent effects.
-------------------------------
kelp forestThe kelp forest is a large population of brown algae that live in marine cool and relatively shallow waters rich in nutrients.
The population density is so high that they are considered to be marine forests, accomplishing many ecosystemic services, such as
absorbing CO₂, releasing a significant amount of O₂, protecting the coasts from waves erosion, and decreasing acidification.They are shelter and source of food for many different species, becoming one of the most diverse and productive habitats.
El Niño Event
The El Nino Southern Oscillation -ENSO- phenomenon occurs due to a complex system of climatic oscillations between the ocean and the atmosphere.
This phenomenon causes significant perturbations in the usual pluvial regimens in the tropics. It provokes
• dry seasons in areas where it usually rains
• rainy seasons in desertic regions.
ENSO phenomenon is dominant in the global climate system.
Under El Niño conditions
A tropical and weak stream in the Pacific acquires strength while the opposite streams debilitate. This change impedes warm water go westward, remaining on America's west coasts. Upwelling does not occur on the America's coasts. In some regions, temperatures rise, and unusual precipitations occur in desertic or dry areas -Atacama desert-. Other affected areas are Eastsouth Asia, Australia, and New Zealand, where there are fewer precipitations and cooler temperatures. Rainfall drops below the average, affecting crops and livestock. Effect of warmer temperatures on the kelp forest
The kelp forest is very sensitive to temperature changes. As a fact, the forest distribution depends on temperature as a limiting factor.
El Niño event has a damaging influence on these forests, not only because they reduce the availability of nutrients but also because they produce a significant change in water temperature.
Ocean warming negatively impacts algae reproduction, growth, and survivorship.
Algae are damaged by the temperature rise to the point of being eliminated.
Associated species composing the marine ecosystem are affected too since they have no refuge, food and live in environments with a higher concentration of CO₂, lower O₂, and more acidification.

18-23 days
Answer :
Incubation is 18 days from the time cockatiels sit in earnest, therefore, count a few extra days if sitting is delayed. Allow the female to abandon the eggs of her own accord rather than removing them even if incubation time is over, because your cockatiel will only lay additional eggs if she reacts to their absence.

Which statement best describes the use of a catalyst in a fuel cell? It reduces waste. It lowers energy requirements. It reduces toxic exhaust. It increases reaction rates.
The statement that best describes the use of a catalyst in a fuel cell is : ( D ) It increases reaction rate
A catalyst in a fuel cell speeds up/facilitates the rate of reaction of oxygen and hydrogen especially at the oxygen electrode of the fuel cell.
Generally catalyst is any substance that increases the rate of a chemical reaction without been used up in the process, while lowering the activation energy required to kickoff the reaction.
Hence we can conclude that the statement that best describes the use of a catalyst is that it increases the reaction rate

this year there were 32 ants born in an ant hive. Due to the new pesticide that was used in the area, 32 died. With an overall population of 1000 ants in the hive, what is the change in population? Do you have a positive, negative, or zero change in population? How many members are in the new population?
Answer should contain the following information: work for calculating the change in population positive, negative, or zero change in population. Work for calculating the new population.
Answer:
0 change in population. I think.
Explanation:
first we are adding 32 ants to the total because 32 ants were born so 1000+32 = 1032.
Next we are subtracting 32 ants from the new total because a pesticinde was used in the area. So 1032 - 32 is 1000. 1000 was the original total so there was not a decrease in popualtion or an increase.

the protein that carries oxygen in our blood is known as
Iron is a component of hemoglobin, which enables it to absorb oxygen from the air we breathe and transport it throughout the body.
What is Hemoglobin?The iron-containing oxygen-transporting metalloprotein known as hemoglobin, often known by the abbreviations Hb or Hgb, is found in the red blood cells of almost all vertebrates as well as some invertebrate organs. The oxygen from the respiratory organs is transported to the rest of the body by hemoglobin in the blood.
The normal ranges for haemoglobin are different for males and females, and they also vary depending on the ethnicity of the population. Additionally, age is a factor, particularly for women.
When you have anemia, your body doesn't produce enough healthy red blood cells to supply your tissues with enough oxygen. Anemia, commonly known as low hemoglobin, can make you feel exhausted and frail.

The fish shown here is normally found in a pond but is being studied in an aquarium. The amount of water and salt intake and excretion is measured as the fish maintains homeostasis. What scientific
question is most likely being asked based on the information in the model?
Based on the information in the question, we can infer that the question being asked is most likely "What mechanisms do fish use to maintain homeostasis in salt-water environments?".
What is homeostasis?Homeostasis is a series of regulatory processes by which an organism maintains core values (or range of values) necessary for everyday life.How to test the questionThe question is in the form of a hypothesis.This means that the scientist must first propose a possible solution to the question.Then, the scientist will make observations based on this question. In this case, it would seem the scientist has placed the fish into an environment that differs from its natural habitat, in order to observe how the fish maintains homeostasis.
Therefore, we can infer that the most likely question being asked is in regards to the way in which fish maintain homeostasis.

Mauna Loa is the largest volcano on Earth with an estimated volume of 9,600 cubic miles (40,000 cubic kilometers). It makes half of the area of the Island of Hawaii. Mauna Loa began to form nearly a million years ago. There is a caldera, Mokuaweoweo, at the summit and rift zones extend to the northeast and southwest.

In one to two sentences, explain why low-pressure systems are associated with bad weather?
Question 2:
In 1–2 sentences, explain what biome comprises most of Antarctica and why the continent is described as being part of this biome.
Answer:
question 1
Low-pressure areas are places where the atmosphere is relatively thin. Winds blow inward toward these areas. This causes air to rise, producing clouds and condensation. Low-pressure areas tend to be well-organized storms
question 2
Scientists that work in Antarctica mostly refer to the majority of the continent as being cold desert or polar desert. The difference between cold and polar desert is very technical, mainly dealing with mineral salt chemistry.

How has vehicle fuel consumption in comparison to miles traveled changed since 1960? What is the likely cause for this change?
Answer:
After World War II, economic growth, population growth, rapid suburbanization, and the closing of some public transit systems led to more reliance on personal vehicles for transportation. The number of cars and trucks in the United States increased dramatically, as did the number of highways.
