Why is it important for the daughter cells to divide a second time in meiosis? Why is it important for the daughter cells to divide a second time in meiosis? The second division forms haploid cells that can combine with other haploid cells during fertilization. Why do you have two sets of chromosomes where did […]
How can we test the properties of matter?
How can we test the properties of matter? Intensive properties, such as density and color, do not depend on the amount of the substance present. Physical properties can be measured without changing a substance’s chemical identity. Chemical properties can be measured only by changing a substance’s chemical identity. What do you call everything you own? […]
What are the elements of Geosphere?
What are the elements of Geosphere? The geosphere has four subcomponents: lithosphere (solid Earth), atmosphere (gaseous envelope), hydrosphere (liquid water), and cryosphere (frozen water) (fig. What is the function of geosphere? Geo means “earth.” The Earth’s geosphere (sometimes called the lithosphere) is the portion of the earth that includes rocks and minerals. It starts at […]
Which is a significant benefit of studying fossils?
Which is a significant benefit of studying fossils? By studying the fossil record we can tell how long life has existed on Earth, and how different plants and animals are related to each other. Often we can work out how and where they lived, and use this information to find out about ancient environments. Fossils […]
How long can a car with a dead battery sit?
How long can a car with a dead battery sit? And what if your car won’t start because of a dead battery? It isn’t a far-fetched possibility, since high-tech vehicles that have computers on monitoring systems need recharging — and if left alone, the battery of such a vehicle could die in about two weeks. […]
Why heat is a matter?
Why heat is a matter? Matter has mass and occupies volume. Heat, light, and other forms of electromagnetic energy do not have measurable mass and can’t be contained in a volume. Matter can be converted into energy, and vice versa. Why are plant leaves different? Why do tree leaves have different shapes? The shape of […]
What is the first step in photosynthesis?
What is the first step in photosynthesis? The first stage of photosynthesis is called the light reactions. During this stage, light is absorbed and transformed to chemical energy in the bonds of NADPH and ATP. Is it true that only plants can make their own food? Green plants are the only organisms in the world […]
What is the importance of knowing how do you use the different weather instrument?
What is the importance of knowing how do you use the different weather instrument? Why are weather instruments important? Weather instruments allow meteorologists the ability to analyze and evaluate the data collected. This data not only details weather over time, but it helps to predict future weather patterns. What is the instrument used to measure […]
How can pressure and flow rate be controlled?
How can pressure and flow rate be controlled? For every pressure, the pump will only deliver one specific flow rate. Therefore, to control the flow of a centrifugal pump, simply set the output pressure to the point on the P-V diagram that allows the pump to deliver the desired flow rate. The output pressure of […]
