both options 4 and 3 is the answer..
Sugar and starch are Carbohydrates.
Answer;
-Tropical rainforest; tropical seasonal forest
In contrast with the tropical rainforest, the soil of the tropical seasonal forest is more nutrient-rich and this type of biome has fewer insects, parasites, and fungal diseases. therefore, in many places, these areas are highly endangered.
Explanation;
The tropical rainforest is one of the world's most threatened biomes, despite being home to some of the most diverse and unique species on the planet. The tropical rainforest is a biome with a constant temperature and a high rainfall. The level of humidity and density of the vegetation give the ecosystem a unique water and nutrient cycle. Rainforests around the world are threatened by human expansion.
The tropical seasonal forest has more or less densely growing trees which lose their leaves during the dry season. It typically contain a range of tree species: only some of which drop some or all of their leaves during the dry season.
Even a country in which the birthrate and death rate are equal can experience population growth if it also has immigration.
- In evolutionary time, migration will often quickly converge gene frequencies among populations. Migration is a powerful mechanism for balancing the gene frequencies of subpopulations in a species in the absence of selection. Gene frequencies will eventually equalize if the migration rate is larger than zero.
- Migration refers to the movement of people, groups, or populations. Migration facilitates gene flow, or the transfer of genes from one population to another, in terms of genetics. Migration—or, to be more precise, gene flow—alone will quickly bring the gene frequencies of the two populations together if they initially had distinct gene frequencies and if selection is not at work.
Therefore, immigration is the correct answer.

The scientist is examining a disaccharide molecule.
Disaccharide is a form of sugar or carbohydrates or is an organic molecule that contains two simple sugars linked together. Like monosaccharides, disaccharides are the sugars soluble in water. Maltose, lactose, and sucrose are some examples.
Monosaccharides are joined to form disaccharide sugars through a condensation reaction, which requires the removal of a water molecule from the functional groups. A type of enzyme called a disaccharidase is used in the process of hydrolysis to separate a double sugar into its two monosaccharides.
