The zygote must contain genetic information from the mother and from the father, so the gametes must contain half of the chromosomes found in normal body cells.
Hope this helps:)
Answer: Mutations can be good or bad.
Explanation:
Answer:
The correct option is B) adaptation
Explanation:
The features and properties of an organism that make it favourable to live in an environment are termed as the adaptations of that organism. Over time, evolution occurs and organisms with better adaptations survive as they are better suited to live in a particular environment. The light-coloured moths were adapted to live on Earth when the colour of the trees had not gone dark. With time, as the colour of trees got darker, the moth had to change colour to be better adapted to live on Earth.
A mass extinction event occurs when a species disappears far more quickly than it is replaced. This is typically understood as the loss of around 75% of all species over a "short" period of geological time, or fewer than 2.8 million years.
An enormous number of species were wiped out by a harsh, worldwide, swift, and selective event is mass extinction. According to marine fossils, at least 75% of all species are thought to have become extinct. The most recent mass extinction is the Cretaceous-Paleogene extinction event, which is also the only one that can be proven to have been caused by a significant asteroid impact. All non-avian dinosaur species, making up about 76 percent of all species on the earth, perished during mass extinction. The Chicxulub asteroid impact in what is now Mexico, which occurred 66 million years ago, caused an ecosystem collapse that resulted in the extinction of the dinosaurs and >75% of all land and sea species as well as the macroevolution of mammals.

Answer:
Gene.
Explanation:
Gene which is responsible for the production of spruceanol in the Peruvian Rosewood plant can be inserted in the host species in order to produce spruceanol in large quantity so that we can used it as a drug that can cure antimalarial disease. There are certain genes that are responsible for the production of spruceanol in the Peruvian Rosewood plant so if we want to produce this spruceanol in other plants we have to transfer this gene to the host plant.
