B. The region experienced a surplus of food
The correct answer is - A. Desertification is increasing, and the desert is expanding.
The Sahara desert has been expanding in the past decades, and it has started to overtake territory south of it. This is mainly due to climate changes, the precipitation has been decreasing, the temperatures have been rising, so the desert has slowly crippled into the territories that were once steppes and savannas. There is an organized action from the people that leave on the borderline of the desert, where they have been thought some techniques as to how to stop the desert growing, and they have gladly accepted it and work hard on it. Initially it seems that there are positive results, but for sure only the time will tell.
Answer:
The carrier lengthen by 7.79 × 10⁻² m when it is traveling in the warm Mediterranean Sea at a temperature of 20° C
Explanation:
The initial length of steel (
) = 371 m
The change in length = ΔL
The change in temperature (ΔT) = 20°C - 2.5°C = 17.5°C
The coefficient of linear expansion of steel (α) = 12 × 10⁻⁶ ⁰C⁻¹
ΔL = αL₀ΔT = 371 × 17.5 × 12 × 10⁻⁶ = 7.79 × 10⁻² m
The carrier lengthen by 7.79 × 10⁻² m when it is traveling in the warm Mediterranean Sea at a temperature of 20° C
Mendel's law or principle that states the gametes that carry one allele is
The Law<span> of Segregation </span>states<span> that </span>every<span> individual organism contains two </span>alleles for each trait<span>, and that these </span>alleles<span> segregate (separate) during meiosis such that </span>each gamete<span> contains only </span>one<span> of the </span>alleles<span>.</span>
