The finches are a type of birds that have lot of variations among them, or rather high speciation. The speciation has been the result of the free niches in the food chains and their adaptations to exploit a particular type of food source. Some finches feed on insects, some on fruits, some on seeds, and that has contributed to different types of beaks among them so that they can be more efficient when it comes to obtaining food. If there are equal amounts of insects, seeds, and fruits in a particular environment, than the numbers of finches that feed upon them will also be roughly the same if there isn't any changes in their food sources. The finches that feed upon the fruits and seeds though will be in higher numbers than the finches that feed upon insects, and the primary reason for this is that the plants are producers, thus they provide more energy, while the insects are consumers, so they provide less energy.
It can be stated that the finches, their numbers, and amount of species, directly depend on the environment and the food sources available in it. As this is a highly adaptable type of bird that often is able to out-compete the other species feeding on the food sources, if there is the slightest gap in the food chain, it will occupy it. The more food sources there are, the larger the population of the finches, and the more different types of food sources there are, the higher the speciation among the finches. The population size though will directly be dependent on the type of food source and the amount of energy it provides for the birds.
Answer:
The cell would not split in two
Explanation:
Each daughter cell has the same number and kind of chromosomes as the parent nucleus If mitosis were not accompanied by cytoplasmic division, there would only be one cell with two identical nuclei because the division did not occur for there to be two different cells.
Sandstone would be the most likely to contain a fossil. Metamorphic and igneous rocks, like pumice, quartz, and obsidian have too much heat and pressure placed on them that it is hard to preserve fossils.
The macromolecules broken down by following enzymes are:
- Nuclease: Nucleotides
- Sucrase: Sucrose
- Lipase: Lipids
- Pepsin: Peptides
Enzymes are the biological catalysts. They function to catalyze the chemical reactions inside any living organism. These enzymes act upon certain molecules called substrates, carry out the reaction in an accelerated manner and then form the product.
Nucleotides are the molecules involved in the formation of genetic material like DNA and RNA. A nucleotide itself is composed of three components: a pentose sugar, a nitrogenous base and a phosphate group. The pentose sugar is different for DNA and RNA. For DNA, it is deoxyribose sugar, whereas for RNA it is ribose sugar.

The neurotransmitters that are partially responsible for the "high" that is associated with passionate love are chemically similar to the drugs, amphetamines.
- The neurotransmitters responsible for passionate love are dopamine, norepinephrine, and serotonin which show similar effects as shown by amphetamines.
- Amphetamines are drugs given to patients to help them deal with mental illnesses like insomnia and depression.
- Passionate love gives the same feelings as taking drugs such as amphetamines.
Thus, the neurotransmitters that are partially responsible for the "high" that is associated with passionate love are chemically similar to the drugs, amphetamines.
