Answer:
Resistance bacteria survive in greater numbers and pass the trait to their offspring
Explanation:
Antibiotics are chemicals which are used in the treatment of bacterial infections. The bacteria sometimes have some form of immunity or resistance to a particular antibiotic due to a host of underlying factors.
Once resistance appears in a bacterial population, it spreads rapidly. The trait of immunity or resistance to such antibiotic is then passed as a trait from one generation to another.

Explanation:
The correct pairing of the homologous chromosomes and their correct segregation (a chromosome for each daughter cell) are key to the proper development of the new cells, and specially of the new individual if we are talking about the early stages of embryogenesis. If there is an error during the splitting of chromosomes, and one cell gets a double set and the other misses a chromosome, numerical chromosomal abnormalities occur. These numerical abnormalities can happen on autosomes or sexual chromosomes, and common examples are as Down Syndrome (trisomy 21), Patau Syndrome (trisomy 13), Turner Syndrome (45,X) and others.
The number of the trisomy indicates the chromosome pair that suffered the adding or the subtraction of its chromosome.

Answer:
The phenomenon in which osteoclast results in the degradation of the old bones and encourages the generation of novel bones by the assistance of osteoblasts is termed as bone remodeling. The remodeling of bones takes place throughout life, that is, whenever it is required. Some of the elements that monitor the process of bone remodeling are the concentration of serum vitamin D, serum level of calcium, and the level of calcitonin and growth hormone in the blood.
Thus, whenever the bone gets degrade or becomes useless it gets replaced by the process of bone remodeling. Hence, the hypothesis of 'use it' here signifies the usage of bones or else they will get useless or get degrade.
In the process of bone remodeling formation of more dense bones takes place due to the renewal of the destructed bones. This results in the presence of both the damaged bones and the newly formed bones at the same time, hence, it can be concluded that more bones are present at the time of bone remodeling.
