Answer:
B. They are fraternal twins.
Explanation: Identical are twins that look alike and are then same
Fraternal twins are twins that don't look alike and aren't the same.
Because I have a twin and we're not identical because he is a boy.
Since the population of finches had decreased when deforestation and logging started, and it returned to its original values prior to deforestation when locals started to replating trees, it follows from these facts that trees are being a limiting factor in finches' populations, either because they're acting as niches, food, both or anything else that these populations needed to survive.
Therefore, the correct answer to this question is option D.

Observation is essential in science. Scientists use observation to collect and record data, which enables them to construct and then test hypotheses and theories. Scientists observe in many ways – with their own senses or with tools such as microscopes, scanners or transmitters to extend their vision or hearing
Answer:
Yellow seed colour (heterozygous)
Explanation:
Since we are performing experiment on the garden pea, so in the garden pea Yellow seed color is dominant and green one is recessive.
The allele responsible for the seed colour is denoted by Y.
So,
Homozygous parent having Yellow seeds will have allelic configuration as YY and the other homozygous parent with green seeds will have yy as pair of alleles.
In the cross of YY × yy the F1 progeny will be Yy which means F1 offspring will will be heterozygous and have Yellow seed colour because Yellow seed colour is dominant over the green colour. Green colour will express itself only in the homozygous condition.
