Answer:
Single-cell organisms
Explanation:
In 1735, Linnaeus introduced a classification system with only two kingdoms: animals and plants. Linnaeus published this system for naming, ranking, and classifying organisms in the book "Systema Naturae". In the epoch that Linnaeus created this system, single-cell organisms such as bacteria and protists were almost unknown. In 1866, E. Haeckel added a category including both bacteria and protozoa, thereby adding a category formed by single-cell organisms (different from animals and plants). During the 1900-1920 period, bacteria were classified as a separated kingdom named 'prokaryotes'. The current three-domain classification system was introduced by C. Woese in 1990. In this system, all forms of life are divided into three different domains: archaea, bacteria, and eukaryote domains (this last composed of protists, fungi, plants and animals).
Answer:
The correct answer would be- 1:1:1:1.
Explanation:
According to the question the cross between the two pea plants with the genotype RrYy and rryy where R for round seeds and r for recessive form that expressed wrinkled seed character. The other character of this dihybrid cross is the color of the seds Y for green and y for yellow seeds.
The cross is shown in the image attached that suggests that phenotypic ratio would be 1:1:1:1 as RrYy, Rryy, rrYy, and rryy.
Thus, the correct answer is : 1:1:1:1.
<span>The calculated to surface area for red blood cells by Gorter and Grendel found to be 36u2.
The surface area that would be covered once they spread across the surface of the water is 72u2.
If they spread across the surface area will double. This is because the lipid bilayer with phospholipid the head faces the water on each surface of the membrane.
It clearly shows that there must be more to membranes than lipid bilayer because membranes grew and the surface tension of membranes is much lower than those of pure lipid structures.</span>
