Explanation:
When chromosomes are duplicated before cells divide, in a process called?
Answer: The process is called Mitosis
Explanation: Mitosis is the process in which a eukaryotic cell (cell containing a nucleus) separates its already duplicated chromosomes (copied during the S phase) into two sets of chromosomes so there will be two identical nuclei. It is generally followed by cytokinesis which divides the cytoplasm and cell membrane.

How did the underwater volcano form?
Answer:
Underwater volcanoes form much like volcanoes on dry land by a process known as subduction.
Explanation:
This occurs as a result of tectonic plates which form the top layer of the Earth's mantle, just below the Earth's crust. They support the weight of the continents and the combined water of the seas.

2. List the abiotic factors you can
identify in the meerkat's habitat
below.
The abiotic factors that are present in the image are the light from the sun, the air, the mountain, the water, etc., as abiotic substances, also known as abiotic factors, are non-living components of an ecosystem.
What are abiotic factors?Abiotic substances include physical and chemical factors that affect the ecosystem, such as water, air, light, temperature, soil, nutrients, minerals, etc, where as water is an abiotic substance and is essential for many cellular processes and regulating body temperature, light is necessary for photosynthesis, which is the process that allows plants to produce energy from sunlight, and temperature is important because it affects the metabolic rate of organisms, and extreme temperatures can cause stress or even death.
Hence, the abiotic factors that are present in the image are the light from the sun, the air, the mountain, the water, etc.

1. Why are earthquakes monitored worldwide instead of in earthquake-prone areas only?
2. How many seismographs are needed to find the epicenter of an earthquake? Why is this
number significant?
Answer:
earthquakes are monitored worldwide because we never know when they will occur, they can happen everywhere in the world even in the areas that are far away from the tectontic plates boundaries. that is why earthquakes are monitored worldwide instead of in earthquake-prone areas only.
Answer:
1. Why are earthquakes monitored worldwide instead of in earthquake-prone areas only?
Earthquakes are monitored worldwide instead of just earthquake-prone areas since earthquakes can happen all over the world, even far away from plate boundaries.
2. How many seismographs are needed to find the epicenter of an earthquake? Why is this number significant?
You need at least three seismographs to find the epicenter of an earthquake. The reason you need three or more seismographs is so you can see where the waves overlap to find the epicenter.
Label all of the components of this DNA structure with the following terms: Phosphate sugar backbone, nitrogenous base, hydrogen bonds.
Answer:
Phosphate sugar backbone:
The sugar-phosphate backbone forms the structural framework of nucleic acids, including DNA and RNA. This backbone is composed of alternating sugar and phosphate groups, and defines directionality of the molecule.
Nitrogenous base:
Nitrogen bases are the molecules that make up the steps of the ladders. There are four different nitrogen bases, namely; Guanine, Thymine,Adenine and Cytosine.
Pyrimidines are compounds that make a single 6-sided ring. Examples of pyrimidines are Cytosine and Thymine.
Purines on the other hand make 5-sided and 6-sided rings. Examples of purines are Guanine and Adenine.
The nitrogen bases are helped together through hydrogen bonds.
Hydrogen Bonds:
A weak bond between two molecules resulting from an electrostatic attraction between a proton in one molecule and an electronegative atom in the other.

Answer:
3. What is the relationship between S- and P-waves?
The relationship between S and P waves is that they both arrive before surface waves, but P waves arrive before S waves.
4. How did the study of earthquake waves lead to a greater understanding of the interior structure of Earth?
The study of seismic waves led to a better understanding of the interior of Earth since these waves travel at different speeds in different materials. This study has helped scientists get a better understanding of the inner components of Earth.

How does the ocean interact with land and air?
Answer:
Explanation:
One way that the world’s ocean affects weather and climate is by playing an important role in keeping our planet warm. The majority of radiation from the sun is absorbed by the ocean, particularly in tropical waters around the equator, where the ocean acts like a massive, heat-retaining solar panel. Land areas also absorb some sunlight, and the atmosphere helps to retain heat that would otherwise quickly radiate into space after sunset.
The ocean doesn't just store solar radiation; it also helps to distribute heat around the globe. When water molecules are heated, they exchange freely with the air in a process called evaporation. Ocean water is constantly evaporating, increasing the temperature and humidity of the surrounding air to form rain and storms that are then carried by trade winds. In fact, almost all rain that falls on land starts off in the ocean. The tropics are particularly rainy because heat absorption, and thus ocean evaporation, is highest in this area.
Outside of Earth’s equatorial areas, weather patterns are driven largely by ocean currents. Currents are movements of ocean water in a continuous flow, created largely by surface winds but also partly by temperature and salinity gradients, Earth’s rotation, and tides. Major current systems typically flow clockwise in the northern hemisphere and counterclockwise in the southern hemisphere, in circular patterns that often trace the coastlines.
Ocean currents act much like a conveyor belt, transporting warm water and precipitation from the equator toward the poles and cold water from the poles back to the tropics. Thus, ocean currents regulate global climate, helping to counteract the uneven distribution of solar radiation reaching Earth’s surface. Without currents in the ocean, regional temperatures would be more extreme—super hot at the equator and frigid toward the poles—and much less of Earth’s land would be habitable.

Read the passage. Then write a paragraph that explains why the two ecosystems have such different kinds of plants. Use the terms biotic factor, abiotic factor, and limiting factor in your explanation.
Passage
A group of students is studying the types of plants that grow in a field next to the school. The field is mowed regularly, but it does not get any water other than rainfall. The field has several kinds of plants that are typically found in a grassland ecosystem. But it has none of the plants found in a nearby forest ecosystem.
Answer:
The reason why the ecosystem has many different kinds of plants is because of the soil, or the environment around them. Also, some biotic factors like animals or humans could be the reason. The humans may have planted seeds there, and probably some abiotic things like soil could also be the reason why. The plants that grow there receive a lot of rain, or the limiting factor is the rain, and the type of plants that grow there don't need much water to survive.

Euglena, Amoeba and paramecium are unicellular organisms. Euglena moves by flagellates, Amoeba by pseudopods and paramecium moves using cilia.
What are unicellular organisms?Unicellular organisms are lower level organisms having only one cell and an undeveloped nucleus. Most of them are aquatic lives and moves using some special organelles.
Amoeba moves by an arm-like structure emerging from its body and contains microtubules within the arms. Euglena is flagellated microorganism moving by flagella.
Paramecium is an aquatic unicellular microorganism having special whip like structure called cilia which moves it in back forth. Ciliary bodies are like oars to move in a direction.
Therefore, amoeba moves by pseudopodium, euglena moves by flagella's and paramecium moves by cilia.
