An open circulatory system simply means that the blood flows out of vessels and into the spaces or sinuses. Invertebrates, insects and crustaceans has an open circulatory system where pump blood goes into a hemocoel and diffusing back to the circulatory system between cells. In other animals, the heart pumps the blood into the body cavities, spaces or sinuses, where the blood surrounds the tissues.

Gregor Mendel observed that two plants with purple flowers could produce some offspring with white flowers and some offspring wi
podryga [215]

Answer:

Heterozygosity

Explanation:

The correct term that could explain the phenomenon is heterozygosity.

<u>In heterozygous condition, a gene is made up of two different alleles in which one would be dominant and the other would be recessive. </u>

<em>In heterozygous purple plants in which the alternate color is white, the white color is not expressed because its allele is in a recessive state. If two heterozygous plants are mated, the recessive allele in each plant would combine into some of the offspring, resulting in the production of white color progeny in addition to the dominant purple color progeny.</em>

Let us assume that the purple color allele is P and the white color is p.

   Pp    x    Pp

 PP  Pp  Pp  pp

PP and Pp - purple color

pp - white color.

hjlf

Answer:

Mutation.

Explanation:

Mutation in the organism's DNA that is passed on to the offspring is that main cause of heritable phenotypic change in some members of a population that reproduces asexually. Repeated exposure of Plasmodium that is sensitive to artesunate strain to increasing dosage of artesunate led to the development of resistance in plasmodium because the genetic mutation occur in the plasmodium that provide resistance against artesunate.

Explanation:

An operon is a cluster of genes that are transcribed together to give a single messenger RNA (mRNA) molecule, which therefore encodes multiple proteins (Fig. 16.11). Such polycistronic mRNA is typically found in prokaryotes.
