Prior to the 1600s it was believed that all living things were either plants or animals. Which of these inventions led to the de
hram777 [196]

Explanation:

Microscopes are instruments used for viewing microscopic cellular structures, not visible with the human eye. With an arrangement of lenses, and manipulation of light or electrons, these magnify very small objects. Light microscopy uses light and multiple lenses, while electron microscopes use electrons. These create larger images of objects.

Subcellular components and molecules require the closed system of the cell in order to function with different arrangements and features being key to certain phyla, groups and species; this aided in the reclassification of organisms into the kingdoms and phyla we know today.

Further Explanation:

Biology's unifying principle states that cells are the basic units of biological organisms. Cells sharing a similar origin, group together in the body to form tissues; these typically share physical features and are arranged in regular patterns. All living things, grow, respire, reproduce etc. these processes are carried out by cells, which are thus integral to their survival.

Before the discovery of cells by Robert Hooke in 1665 with a simple microscope, many scientists had long believed that life rose spontaneously over extended periods of time. Circa 1668 Francesco Redi, challenged the idea of spontaneous generation of maggots from rotting meat by placing meat in various sealed open, partially sealed and sealed containers. Sealed containers did not show the presence of maggots, and he theorized that these were likely from eggs laid on the meat by flies. This was the development of the theory of abiogenesis (cells arise from other living cells); this eventually proved the unifying principle we know today.

Cell theory states that living things are comprised of cells, as their smallest units capable of functioning. Microscopy helps to prove this, as cells and their varying components can readily be seen, observed and later classified. Their components and molecules require the closed system of the cell in order to function with different arrangements and features being key to certain phyla, groups and species; this aided in the reclassification of organisms into the kingdoms and phyla we know today.

2. A population of salamanders has two colors, blue and white. Blue is the dominant color and white is recessive. The frequency
AysviL [449]

The percentage of the white salamander population is 16%.

<h3>Hardy-Weinberg Equilibrium Equation</h3>

The genotypic frequencies within a population can be expressed by the binomial (p + q)² = 1, which can be developed and represented by the following equation:

  • p² + 2pq + q² = 1

p = frequency of the dominant allele;

q = frequency of the recessive allele;

p² = frequency of the zygous dominant genotype;

2pq = frequency of the heterozygous genotype;

q² = frequency of the zygous recessive genotype.

Also according to the equation presented (p² + 2pq + q² = 1), we will have the following distribution of genotypes:

  • CC = 0.36 = 36%
  • Cc = 0.48 = 48%
  • cc = 0.16 = 16%
