Answer:

1. Atoms;tissue

2. Cell

3. Organ

4. True

5. Atom

6. Molecule

Explanation:

Biology which is the study of life has been divided into different levels of organization for the convenience to study. The levels or organization can be represented as follows:

Atoms - molecules - cell - Tissue - organ - organ system - Organism - population - community - ecosystem - biosphere.

Cell is the simplest functional unit of living organism. Different cells have different functions and each cell carry the genetic information i.e the DNA. Cells with similar structure and function come together to form tissues. Tissues like epithelial tissue, connective tissue, muscular tissue and nervous tissue. Specific tissues with specialized functions come together to form the organ. In humans there are various organs but all are under the control of brain. Group of organs working together form the organ system. For example digestive system is made of organs such as stomach, small intestine, large intestine, pancreas. All the organ systems together make the organism. Within organism the most complex level of organization is organ system.

3. How would you differentiate between natural selection and artificial selection<br>

slava [35]

Answer:

Natural selection is the process whereby organisms better adapted to their environment tend to survive and produce more offspring. The theory of its action was first fully expounded by Charles Darwin and is now believed to be the main process that brings about evolution while Artificial selection is Selective breeding is the process by which humans use animal breeding and plant breeding to selectively develop particular phenotypic traits by choosing which typically animal or plant males and females will sexually reproduce and have offspring together.

Knowing that the genetic code is universal, scientists use molecular biological methods to insert the human beta-globin gene int

Radda [10]

Answer is given below :

Explanation:

When the beta-globin gene is inserted into the bacterial chromosome, during insertion, beta-globin forms a stop codon between the coding sequences of beta globin, resulting in a reduced amino peptide. Acid on translation
Furthermore beta-globins form a tertiary protein complex with alpha-globin, which in addition to the ham-subgroup forms functional hemoglobin.
Since we only put the beta-globin gene on the bacterium-chromosome that is not enough to make a functional protein, we found a non-functional protein
