Answer:
<em><u>There are two important types of genetic mechanisms that can give rise to antibiotic resistance: mutation and acquisition of new genetic material. In the case of mutation, the rate at which resistance develops can be attributed to the rate at which bacteria mutate.</u></em>
We have food water and air. We also have shelter.
Food,Water,Shelter,Air is the answer.
Answer: b - Chondroblasts within the cartilage divide and secrete new matrix
Explanation: Chondroblasts are derived from two sources; mesenchymal cells within the center of chondrification and chondrogenic cells of the inner cellular layer of the perichondrium (coverings that lie over most cartilage).
At the chondrification centers, the cartilage forming cells (Chondroblasts) begin to secrete the components of extracellular matrix of cartilage. As the amount of matrix increases, the Chondroblasts become separated from each other and they are located in small cavity within the matrix called lacunae.
Concurrently, the cells differentiate into matured cartilage cells called chondrocytes.
Answer:
Physiology, behavior and morphology are considered as phenotype of an individual as these attributes can be observed. Example of phenotypes include wing length, hair color, skin color and height.
<u>There are basically two factors that influence the phenotype:</u>
<u>(1) Genotype or Genetic information of the individual:</u> Some of the phenotypes such as height and skin color are transmitted genetically from generation to generation. Genetic information is the transfer of genes that carry some of the specific genetic information and pass it to another generation which is visible in their phenotype.
(2)<u> Environmental influence:</u> As the phenotype attributes are variable so they are highly influenced by the environment or surrounding they are living. Environmental condition such as temperature, diet, humidity, oxygen levels, and the presence of mutagens affects the phenotype of an individual.
Hence, Genotype and environmental factors influence an individuals phenotype.
