Chromosomes! They contain the recipe for making a living thing. They are found in almost every cell's nucleus and are made from strands of deoxyribonucleic adic (DNA)
Answer:
A. near-Earth objects.
Explanation:
Science can be defined as a branch of intellectual and practical study which systematically observe a body of fact in relation to the structure and behavior of non-living and living organisms (animals, plants and humans) in the natural world through experiments.
When scientists discuss objects that might hit Earth, the term which they use to describe them as a group is near-Earth objects.
A near-Earth objects can be defined as a small solar system body such as comets and asteroids whose orbit draws it close or in proximity to the earth's orbit due to the gravitational force of attraction of nearby planetary bodies.
Basically, if the closest approach of a planetary body to the Sun is less than 1.3 AU it is considered to be a near-Earth objects.
Hence, near-Earth objects may pose a collision danger to planet earth.
Answer:
Kidneys
Explanation:
The kidneys remove wastes and excess water in the body through the urine, as urine flows from the kidneys to the bladder through two thin tubes located on both sides of the bladder called the ureter, and the bladder stores urine, and each of the kidneys consists of about one million filtering units called the renal tubular unit contains Each renal tubular unit has a filter called the glomerulus and tubule, and the renal tubular unit operates through a two-step process:
glomerulus: filters blood.
Tubule: Returns the necessary substances to the blood and removes waste.
Answer:
mitosis
Explanation:
mitosis occurs after DNA in the nucleus has doubled
Distillation is the process of separation in which the volatile parts of a liquid mixture are separated by selective boiling and condensation. This process may lead to partial separation or complete separation. Distillation is employed for a considerable number of commercial processes such as the production of alcohol, kerosene gasoline, etc. During a distillation, it is important that a drop of condensate be suspended from the thermometer because it allows steady distillation and a stable temperature.
