What is the importance of biodiversity in sustainable development? Biodiversity is essential for sustainable development and human well-being. It underpins the provision of food, fibre and water; it mitigates and provides resilience to climate change; it supports human health, and provides jobs in agriculture, fisheries, forestry and many other sectors. What is an example of […]

How do you find the volume of a doghouse? You can find volume by multiplying length times width time height. How do you find the volume of a hut? Multiply length x width x height The formula for the volume of the rectangular structure is L x W x H1. The example structure is 80 […]

Is a 10 mW laser dangerous? If you look at the dot from a 10,000 mW (10 W) visible laser within 1.8 feet (60 cm) for more than 10 seconds, this could potentially cause a retinal burn. In summary, looking at a diffuse line of red light from a Class IIIa (3R) laser, even for […]

How many dimensions did Einstein theorize? We see the world around us in three dimensions. Einstein predicted a fourth which he called space/time. He theorized energy from colliding black holes causes gravitational waves that pass through objects without changing. That makes them nearly possible to measure or prove that they exist. What is a 8d […]

How do you ask for a humble request? However, to say that you are doing something “humbly” might sound overly formal. If you would like to make a polite request of someone, you could use the phrase, “I would like to request that you…” How do you write a formal email asking for help? Polite […]

How do you describe a signal transduction pathway? Signal transduction pathway involves the binding of extracellular signaling molecules and ligands to receptors located on the cell surface or inside the cell that trigger events inside the cell, to invoke a response. The response can then alter the cell’s metabolism, shape, and gene expression (Krauss, 2006). […]

How much more heat is produced if current is doubled 1 point 4 the original amount 4 times the original amount 5 times the original amount? ×RtasV=IR. RtJ. R×t). Hence, if the current passing through an electric bell is doubled, the heat produced will become four times more. How much more it is produced if […]

How accurate is TLE? A value of 1 arcsec (2:8 10 4 deg), which equals in GEO 0.18 km, and is well below the intrinsic errors for GEO and HEO objects. The data in TLE format itself are limited to an accuracy of 35 m as explained previously. How accurate is SGP4? An Accuracy Analysis […]

What is the relationship between colonialism and exploitation? Exploitation colonialism is the national economic policy of conquering a country to exploit its population as labour and its natural resources as raw material. How did European exploit America? Europeans traded for slaves with the slave capturers of the local native African tribes in exchange for rum, […]

Why is green light not absorbed by plants? In conclusion, plant leaves are green because green light is less efficiently absorbed by chlorophylls a and b than red or blue light, and therefore green light has a higher probability to become diffusely reflected from cell walls than red or blue light. Chlorophylls do not reflect […]
