1. While observing cork through his microscope, Hooke saw tiny boxlike cavities, which he illustrated and described as cells.
2. D. Robert Koch developed a way to prove that a specific microbe caused a particular disease. Matthias Jakob Schleiden suggested that ALL plants are made of cells.
3. Anton van Leeuwenhoek is another scientist who saw these cells soon after Hooke did. He made use of a microscope containing improved lenses that could magnify objects almost 300-fold, or 270x. ... He also found for the first time the sperm cells of animals and humans.
4. Antonie van Leeuwenhoek used single-lens microscopes, which he made, to make the first observations of bacteria and protozoa. His extensive research on the growth of small animals such as fleas, mussels, and eels helped disprove the theory of spontaneous generation of life.

The experimental process of determining the relative location of genes or other segments of dna along individual chromosomes is

Tatiana [17]

The experimental process of determining the relative location of genes or other segments of DNA along individual chromosomes is called Genome mapping or chromosome mapping.

Deoxyribonucleic acid is a polymer made of two polynucleotide chains that coil around one another to form a double helix and which contains the genetic material necessary for all known creatures, including many viruses, to develop, function, grow, and reproduce. Nucleic acids include DNA and ribonucleic acid (RNA). Nucleic acids are one of the four main categories of macromolecules that are necessary for all known forms of life, along with proteins, lipids, and complex carbohydrates (polysaccharides).

Because the two DNA strands are made up of simpler monomeric units termed nucleotides, they are referred to as polynucleotides.

Marine mammals, with a few exceptions, are<br> a. oviparous<br> b. ovoviviparous<br> c. viviparous

RUDIKE [14]

Marine mammals , with few exception are viviparous.

Explanation:

Mammals are those animals which are characterized by the presence of mammary gland and body hair.
They feed milk to their young ones.
The vertebrates are classified as viviparous, oviparous and ovoviviparous depending on the way their young ones develop and are nourished during their embryonic and foetal development.
Viviparous animals are those which directly give birth to their young ones and have a distinct gestation period during which their babues develop inside their womb. These are placental mammals.
Oviparous animals are those which lay egg and the embryo develops outside mothers body.
Ovoviviparous animals are those who do not lay their eggs but their eggs hatch inside their body .These are aplacental animals.
Most mammals are viviparous.
