Can population programs alone End Hunger?
Can population programs alone End Hunger? The world has made great progress in reducing hunger: there are 300 million fewer hungry people than in 1990-92, despite a 1.9 billion increase in the world’s population. But there is still a long way to go, and no one organization can achieve Zero Hunger if it works alone. […]
What factors influence how fast nerve impulses travel?
What factors influence how fast nerve impulses travel? The speed is affected by 3 factors: Temperature – The higher the temperature, the faster the speed. Axon diameter – The larger the diameter, the faster the speed. Myelin sheath – Only vertebrates have a myelin sheath surrounding their neurones. What will increase the length constant of […]
What is the meaning of electric current?
What is the meaning of electric current? Electric current, any movement of electric charge carriers, such as subatomic charged particles (e.g., electrons having negative charge, protons having positive charge), ions (atoms that have lost or gained one or more electrons), or holes (electron deficiencies that may be thought of as positive particles). What is an […]
Is green light healthy?
Is green light healthy? Green light therapy, fibromyalgia, and other pain-related conditions. It’s not just migraine, but chronic pain conditions that may be helped by green light therapy. For example, green light was shown to have a positive effect on pain from fibromyalgia—a condition marked by widespread pain, sleep problems, and fatigue. Does green light […]
Why can a batter hit a pitched baseball further than a ball tossed in the air by the batter?
How do you revive soil fertility?
How do you revive soil fertility? Compost is a mixture of decomposed plant parts and animal waste. The key benefit of composting is that it increases soil organic matter content. Organic matter improves the soil fertility, the soil structure and its water holding capacity. It also sequesters carbon in the soil. How can we improve […]
Which two cells structures work together in the process of protein synthesis?
Which two cells structures work together in the process of protein synthesis? The two cell structures that are involved in protein synthesis are the ribosome and the endoplasmic reticulum. What part of cell produces proteins? The endoplasmic reticulum can either be smooth or rough, and in general its function is to produce proteins for the […]
How do you solve a density problem?
How do you solve a density problem? The Density Calculator uses the formula p=m/V, or density (p) is equal to mass (m) divided by volume (V). The calculator can use any two of the values to calculate the third. Density is defined as mass per unit volume. What is the density of milk? Density Product […]
