Answer:
The ozone layer is being depleted due to CFC's. CFC's are found in aersoal spray cans and refrigants, when they are released into the atmosphere it causes depletion of the ozone layer. Humans are the one who made the CFC's, causing the ozone layer to deplete, even though they have been banned now, a lot of damage has been done.

Answer:
The heritability of type 1 diabetes is likely high, indicating that genetics plays a larger role in the development of type 1 diabetes than the environment.
Explanation:
Identical twins are formed when a single zygote separates into two embryos after the process of fertilization. Hence, these twins arise from the same egg and sperm.
Fraternal twins arise when two different sperms fertilize two eggs at the same time.
Hence, we can say that the genotype of the identical twins is similar.
The results from concordance data prove that genetics play a higher role in type 1 diabetes.
In order to improve the graph and make it more detailed in order to get a better perception why the honey bee populations are decreasing, there's few things that can be added.
- Number of bee keepers over the period
The number of the honey bee colonies is directly connected as to how many bee keepers there are. If there's a trend of a decline in the bee keepers, than there will be a trend in the decline of the honey bees.
- Area of trees suitable for the honey bees
The trees are crucial for the honey bees to be able to produce honey, thus it is very important that they have a certain area of trees on which they can feed upon. If there's a decline in the number of trees for the bees, than the bees will be dying from starvation.
- Pollution
The honey bees are animals that are very sensitive to changes in the environment, especially when it comes to pollution. If the levels of pollution are increasing in areas where there's honey bees, it will certainly affect their numbers in a negative manner.
Answer:
The role of carbon in biological systems is to allow the formation of organic molecules, in addition to providing energy for living beings.
Explanation:
Carbon is the fourth most abundant element on earth and one of the main elements of the viological systems, and its presence is essential for life on the planet to be maintained.
Carbon is necessary for all living beings, without exception. This is because it is used in the construction of organic molecules without which no living thing can survive, in addition to providing energy when it participates in sugar molecules, such as carbohydrates.
The new species come from old ancestors of the animals that were there, over time they slowly evolved, and they adapted to that new environment.
