Answer:
Protozoology should be the answer.
<span>Well water draws from the sources of water beneath the Earth's surface. This type of water supply is known as "groundwater."
</span><span>Groundwater includes water that flows naturally from below the Earth's surface to the surface by way of springs. Some springs run entirely underground and do not break through the surface. Groundwater also includes water that is contained in a variety of porous materials that lie beneath the Earth's surface, such as silt, gravel, clay and sand. Water collects below ground in these porous materials into structures called aquifers. Generally speaking, well water collects into the well from these water-bearing structures. Wells are situated in the Earth to access the aquifer at a depth well below the surface.</span>
The answer is <span>A) stimuli receiver, sensory neuron, central nervous system, motor neuron, muscle or gland.
Stimuli receiver receives an information. </span><span>The information is sent through a sensory neuron to the spinal cord, as a part of the central nervous system. </span><span>The spinal cord receives information from the body and relays it to the brain. It, then, receives information from the brain and relays it out through a motor neuron to the effectors (muscles or glands).</span>

probably not organic, unhealthy
Answer:
e. Red segregated from brown in meiosis I, and straight segregated from curled in meiosis I.
Explanation:
A cross between two flies heterozygous for both genes produced an offspring with the phenotypic ratio of 9:3:3:1. This ratio is expected according to Mendel's law of independent assortment, which states that alleles of the same gene assort independently during gamete formation.
Before meiosis starts in flies, a single diploid cell duplicates its DNA, so each chromosome has 2 sister chromatids that contain the same information.
- During meiosis I, <u>the homologous chromosomes separate</u> into two daughter cells. The chromosome number is reduced by half, but each chromosome has two sister chromatids.
- During meiosis II, <u>the sister chromatids separate</u> and each daughter cell from meiosis I divides into two new daughter cells (to get the total of 4 haploid cells).
In a heterozygous fly, each homologous chromosome contains a different allele, and the sister chromatids are copies that carry the same allele. For that reason, both traits were segregated during meiosis I.
