Explanation:

Since scientific terms are harder to understand, some common prefixes (word added to beginning of another) , suffixes (word added at the end) and root words can be used to correctly guess the meaning of a biological term. Most of the terms have been derived from ancient Greek and Roman words.

  1. The prefix omni- means all. E.g, an omnivore is a type of animal that eats both plants and animals.
  2. Prim- is a prefix that means first or foremost. In some cases, it also means basic or fundamental. E.g the primal instincts of any animal are its basic and innate characteristics.
  3. Vor is a suffix that mean eat or devour. E.g, carnivore is an animal that eats meat.
  4. Oligo is a prefix that means few or little. E.g, oligosaccharide is a carbohydrate containing few sugar molecules.
  5. The prefix sub- means both under and below. E.g, subcutaneous means under the layer of the skin.
  6. The prefix sub- means both under and below. E.g, subcutaneous means under the layer of the skin.
  7. The prefix de- means remove, away from or down. E.g to degrade means to break down or break away.
  8. The prefix de- means remove, away from or down. E.g to degrade means to break down or break away.
  9. The prefix de- means remove, away from or down. E.g to degrade means to break down or break away.
  10. The prefix hydro means water. E.g, hydroelectric power is energy derived from water.
  11. Carn is a prefix that means flesh or meat. E.g, a carnivore is an animal that eats meat.
  12. The prefix zoo or zoa defines an animal or of animal origin. E.g, zoology i.e. the study of animals.
  13. The suffix, -cide means to kill or destroy. E.g, fungicide is a chemical that kills fungi.
  14. Auto is a prefix that means self. E.g, autophagy is the pahgocytosis or engulfing of the body cells by other cells of the body.
  15. Inter is a prefix that means between. E.g, intercellular means between the cells.
  16. The prefix heter or hetero means different or other. E.g, heterogeneous is a type of mixture that contains different types of elements.
  17. Troph is a suffix that means feed or nutrition or nourishment. E.g, autotroph is an organism that produces its food by itself.
  18. Calor means heat. E.g, calorimeter is an instrument that measures heat or change in heat.
  19. Ultra is a prefix that mean beyond. E.g, ultrasonics are sound waves that are beyond the audible hearing range.
  20. Intra is a prefix that means within. E.g, intracellular means within or in the cell.
  21. Photo is a prefix that means light. E.g, photosynthesis is a process that plants use to make food by capturing light.
  22. Para is a prefix that means beside, near, equal or alongside. E.g parathyroid is a gland near the thyroid gland.

Explain how body cells (somatic) and sex cells (gametes) are made up from chromosomes?
lana [24]

゚+*:ꔫ:*﹤  ﹥*:ꔫ:*+゚Answer:゚+*:ꔫ:*﹤  ﹥*:ꔫ:*+゚

Somatic cells are produced through the cell division process of mitosis. ... Cells with two copies of each chromosome are called diploid. Sperm and egg cells, called gametes, are formed through meiosis, which is a slightly different cell division process that results in the cells having only one copy of each chromosome.

゚+*:ꔫ:*﹤  ﹥*:ꔫ:*+゚Explanation:゚+*:ꔫ:*﹤  ﹥*:ꔫ:*+゚

Human body cells (somatic cells) have 46 chromosomes. A somatic cell contains two matched sets of chromosomes, a configuration known as diploid. ... Human cells that contain one set of 23 chromosomes are called gametes, or sex cells; these eggs and sperm are designated n, or haploid.

When you open the door to your house on a cold day, you feel a cold draft. What causes
wariber [46]

Answer:

4. Warm air from the inside moving toward the cold air outside.

Explanation:

A cold draft can be defined as the process in which a current of cold air is being drawn in from the outside. Also, it involves the process in which a current of warm inside air exits or leaves a building through an opening.

This ultimately implies that, when you open the door to your house on a cold day, you would feel a cold draft as a result of the movement between the warm air from the inside moving toward the cold air outside. The warm air that were trapped inside your house would escape through the door due to a difference between the outside (cold) and inside (warm) atmospheric pressure.

Hence, a difference in temperature and atmospheric pressure between the outside and inside air usually causes a cold draft.

<em>Additionally, air typically moves or travels from a region of high pressure to a region of lower pressure. </em>
