The results that have been produced from the improved agricultural practices are the following: increased biodiversity, increased productivity, and increased profits. Improved agricultural practices aim to produce food for consumers that are safe and wholesome. If these agricultural practices are improved and applied, there will be an increase in biodiversity as well as increased in productivity. If there is an increase in production, there is an increase in profits.
Answer:
The sun gets its energy from the process of nuclear fusion. This process occurs in the sun's core or interior, where temperature and pressure are extremely high. During most of the sun's life, energy comes from the fusion of hydrogen nuclei
Explanation:
Answer:
The correct answer is- Normal vaginal pH is acidic (4 to 5), which protects from infection.
Explanation:
The vaginal part in woman have high tendency to get infection because of moist internal condition and its location but vagina also have a protective mechanism which protect it from the infection.
A woman's vagina contains many species of Lactobacillus genus which secrete lactic acid and hydrogen peroxide that maintains the low pH level in the vagina. So due to this reason, the normal pH of the vagina remains between 4-5 which does not allow pathogenic bacteria to flourish and cause infection.
Answer: C. The C horizon is very deep.
Horizons are the layers of soil develops as a result of soil formation. Horizon lies parallel to the earth surface. Each horizon differs from the other on the basis of amount or organic matter present, color of the soil, texture of soil and other components making up horizon, and amount and type of minerals present in the soil.
C horizon is the horizon that lies deeper region of the collective soil horizon. It consist of unweathered or partially weathered rocks or their aggregates. Therefore, it retains the original chemical composition of the parent rock. This results in the higher mineral content as compared to other horizons. This horizon also lacks the organic matter as no or very little decomposition activity of plant and animal matter takes place. Therefore, color of soil in this horizon in the absence of organic matter remains light.
Hence, a sample of soil from a C horizon is light brown in color and has a high content of a mineral called feldspar is because of the fact that the C horizon is very deep.
Hibernation is a way animals conserve energy to survive adverse weather conditions or lack of food.
