grigory [225]

Answer:

The right answer is B. The offspring are genetically distinct ... by sexual reproduction.

Explanation:

Sexual reproduction, as opposed to asexual reproduction, indicates that the propagation of a species involves male and female gametes. It is the main method of reproduction of multicellular organisms.

In the first stage of sexual reproduction, meiosis, the number of chromosomes is reduced from a diploid number (2n) to a haploid number (n). During fertilization ("fertilization"), haploid gametes come together to form a diploid zygote and restore the initial number of chromosomes (2n).

Which objects allow humans to access groundwater? Check all that apply.
Masja [62]
<h2>Answer:</h2>

<u>The objects that allow humans to access ground water are:</u>

  • <u>A spring</u>
  • <u>a well drilled into an aquifer </u>
  • <u>a well drilled below the water table</u>
<h2>Explanation:</h2>

Access to ground water can be gained if we dig a well or use any source that can provide us an access below the water table. A water table is the level below which the ground is saturated with water. So above the saturation level we cannot gain access to water therefore we must go below it. A spring springs from ground below water table and the same thing occurs for well or an aquifer if it is below the water table..
