Answer:
Is a push or a pull that causes a moving object to change it's motion; makes objects move or stop; can make an object that is standing still start to move in the direction of the force; can make an object move faster, slow down, stop, or change position. friction.
Answer:
The correct answer is option c) "gram-positive streptococci".
Explanation:
Gram-positive bacteria are stained purple by crystal violet coloration, result of the cell wall interaction with the dye. On the other hand, streptococci are spherical-shaped microorganisms linked in a chain or a raw, which also are gram-positive. Therefore, the correct terminology of the bacteria observed in the laboratory will be a gram-positive streptococci.
Tycho Brahe play in determining planetary orbits his model allowed the path of the planet Mars to cross through the path of the sun. Thus, option B is correct.
<h3>What was Tycho Brahe's greatest contribution to astronomy?</h3>
He rater utilize the telescope to create vast astronomical remarks. He resolved that the planets circle the Sun in oval orbits.
He offered some easy laws that rule the motion of the planets and other entity.
Thus, option B is correct.

In a given homologous chromosome pair, two recombinant chromatids are generated by a single crossover event.
Homologous chromosomes are the chromosomes that possess the same genes at the same loci and also have the same structure. One chromosome of the homologous pair is paternal while the other is maternal. Crossing over even takes lace between homologous chromosomes only.
Crossing over is the event that involves the interchange of genetic material between homologous chromosomes. Due to this event, the offspring receives genes from both the parents. The exchange of genetic material occurs between two non-sister chromatids in crossover, hence two recombinants are obtained.
