Answer:
Characteristics of polar molecule
- they should have opposite charge
- they should have same dipole moment value
- they should have electronegativity different
Explanation:
Polar molecule is characterized by an uneven distribution of the electrons that form the covalent bonds between each atoms in the molecule
Polar molecules has a net dipole as a result of opposing charges from polar bonds, since water has slightly positively charged side and a slightly negatively charged side. This makes it a polar molecule
Answer:
The correct answer will be option-D
Explanation:
Stem cells are the cells which have the ability to form different types of cells. They differentiate and specializes to perform different functions in the body and thus forms the different cells.
The differentiation and specialization are controlled at the gene level by different patterns of gene expression. The pattern of gene expression is not fully understood during development but research have shown that the gene expression is influenced by the different environmental signals and internal regulators.
Thus, option-D is the correct answer.
Sexual Reproduction: Sexual reproduction promotes genetic variation by producing different gene combinations. Meiosis is the process by which sex cells or gametes are created. ... The genetic recombination of genes also occurs during crossing over or the swapping of gene segments in homologous chromosomes during meiosis.
Answer: Uses glucose ;produces carbon dioxide
Explanation:
Cellular respiration can be defined as the process by which the chemical energy in the body is transferred into ATP and some of it is released in the form of heat.
During this process the glucose that is broken down and the energy released is converted into ATP.
Carbon dioxide is released as a by-product of this process.
Hence, the correct answer is option C and D
