Cool topic you're learning about. Antibiotic resistance occurs because of the fact that bacteria change in response to the use of medicaments, such as penicillin. The problem about antibiotic resistance, an international health crisis, is that people OVERDOSE in medicaments. Antibiotics are known to kill weak and sensitive bacteria, but some resistant bacteria grow and multiplicate, since they know how the medicament works.
Therefore, I would say that bacteria that are not initially killed by the antibiotic, they go to reproduce passing the resistance on to offspring. Antibiotic resistance is a big example when it comes to natural selection.

Answer:
<h2>
All the gametes are 25%; SY(25% so on) Sy, sY, and sy .
</h2>
Explanation:
Spherical shape (S) is dominant over dented shape(s), so S is dominant over s;
Yellow (Y) is dominant over white color (y), so Y is dominant over y.
Here as given, parent is heterozygous for both parents.
so its genotype is= SsYy
Gametes formation follow both law of segregation and law of independent assortment:
So, 25% of gametes are SY
25% of gametes are Sy
25% of gametes are sY
25% of gametes are sy.
tuberculosis is transmitted through the air, not by surface contact. Transmission occurs when a person inhales droplet nuclei containing M. tuberculosis, and the droplet nuclei traverse the mouth or nasal passages, upper respiratory tract, and bronchi to reach the alveoli of the lungs
