Answer:
Flatworms are beings that do not have a heart, veins, arteries, capillaries, hemolymph, or some type of circulatory fluid. Their circulation occurs between cells or intercellularly and they are responsible for transporting substances by diffusion from cell to cell.
Explanation:
Flatworms are considered multicellular eukaryotic organisms. This implies that in their cells they have a cellular nucleus, in which the DNA is contained, structuring the chromosomes. Likewise, they are made up of several types of cells, each one specialized in a specific function. They lack a structured circulatory system as such. Because of this they do not have specialized structures such as a heart or blood vessels, however, the circulation of certain substances is established between their cells. This is done thanks to the diffusion process. Substances pass from one cell to another through this process.This does not apply to all flatworms, since in some species of bog and digenae there is a certain organization and some very small conducting vessels known as the endolymphatic system, the which forms a kind of plexus in the parenchyma.It should also be noted that some species do not even have a digestive system, being the digestive tract the one in charge of digestive functions and the distribution of the nutrients they receive.
Answer:
1st has A and G whereas 2nd has C and T.
Explanation:
There are three common haplotypes present in the population. The first single nucleotide polymorphism has A and G alleles while on the other hand, the second single nucleotide polymorphism has C and T alleles. The four possible combinations of haplotypes for the above two single nucleotide polymorphisms are AC, AT, GC, and GT.
Answer: 100mL sucrose solution and 900mL water
Explanation: sucrose solution is 500 mM, i.e. 500mmol/L
water is 0mmol/L
To get 50mmol/L we need 1/10 L of sucrose solution = 100mL
and made up to 1L with water
Answer:
They are about 1/10th the size of a typical human cell. Microbes are generally measured in the scale of one millionth of a meter, which is known as a micrometer.
