2. During differentiation, certain genes are activated to produce proteins that enable specific functions.
3. Meiosis results in offspring with genotypes that are not exact copies of the parents.
4. DNA replication occurs before the division of the nucleus.
5. I can't answer without the image.
6. ovary cells (and testes in males)
7. I can't answer without the image.
8. It was passed to the individual by a gamete from the father.
9. 3n
11. Need the diagram.
d. CO (carbon monoxide) is not an acidic oxide.
Acidic oxides are those oxides which either act as acceptors of the hydroxide ions (OH-) and function as a Lewis acid or they produce an acidic solution when added to water. Examples of acidic oxides are P4O10 (Phosphorus pentoxide), P4O6 (Tetraphosphorus hexaoxide), SO3 (Sulfur trioxide), SiO2 (Silicon dioxide) etc.
Neutral oxides do not show either of the basic or acidic properties. Due to this fact, they do not form salts when they react with acids or bases. Examples of neutral oxides include CO (carbon monoxide), NO (Nitric oxide), N2O (Nitrous oxide) etc.
Hence, option d is correct.

Answer:TT (tall plant)
Explanation:
When a Tall plant (TT) is crossed with tt (Short plant) all the offspring will be tall because T is dominant over small t. This happen in the first filail generation.
TT×tt
Tt Tt Tt Tt- all tall pea plant.
Complete dominant occurs when a dominant allele expresses itself over a recessive allele such that the phenotype expressed is of the dominant traits.
They both rely on other organisms for food. In other words, they are consumers. They both somehow "hunt" for food, with carnivores exerting more effort as majority of their food sources will be running away from them, thus more effort is needed compared to the herbivores.
Answer:
Natural selection
Explanation:
According to Darwin, natural selection is the mechanism through which evolution takes place. Natural selection is the mechanism through which the heritable traits characteristic changes in an organism over the generations. Variations in traits of organisms are passed down through the generations and each generation has their genes affected by the environment.
