What was significant to darwin about the fauna and flora of the galápagos islands?.
The significant to darwin about the fauna and the flora of the galápagos islands is The species were similar to the South American species, indicating the common descent, but they had been the extensively modified and were well-adapted to the island life
in Galapagos he found a remarkable population of the plants, birds and the reptiles that had been developed as isolation from the mainland, but they often differed on the almost identical islands next door to one of another and whose characteristics that he could only explain by the gradual transformation of the various species. Over time, the Darwin began to wonder if the species from the South America that had reached the Galapagos and then he changed as they had adapted to new environments. This idea—that species and that could be change over the time—eventually this led to Darwin's theory of evolution by the natural selection

The term "greenhouse gas" refers to a group of gases that also includes carbon dioxide, methane, nitrous oxide, ozone, and organic substances known as chlorofluorocarbons (CFCs).
What role does ozone play in the greenhouse effect?Two things happen to the Earth's temperature equilibrium as a result of atmospheric ozone. The UV energy from the sun is absorbed by it, warming the stratosphere. Infrared light from the Earth's surface is also absorbed by it, which effectively traps heat in the troposphere.
Carbon dioxide, methane, nitrous oxide, hydrochlorofluorocarbons (HCFCs), hydrofluorocarbons (HFCs), and ozone in the lower atmosphere are the principal greenhouse gases whose concentrations are growing.

After a natural disturbance causes mortality in a population, there is a change in the population's gene pool. this is known as a Bottleneck Effect.
Bottleneck Effect- The bottleneck effect is a phenomena that occurs when a population's gene pool suddenly shrinks as a result of a natural environmental occurrence, a natural disaster, a disease, or human activity. A bias that wasn't there in the initial population will probably result from this shrinkage of the gene pool.
Gene Pool- A gene pool is the collection of all the alleles (including alleles) found in a population or species that is capable of reproduction. A big gene pool has a wide range of genetic diversity and is more resilient to environmental stresses.

To reflect the triangle across the x-axis, we'll have to plot the following points:
Given,
A (4, 5)
B (-2, 7)
C (-6, 3)
A' (4, -5)
So, points B' and C' will also be equidistant from the x-axis, similar to the distance of points B and C from x-axis.
Therefore,
B' will be plotted with the coordinates (-2, -7)
and, C' will be plotted with the coordinates (-6, -3)
According to the meaning of a point reflecting through any axis, a point's perpendicular distance from any axis selected as the line of reflection from the image and pre-image is constant.In order to make a mirror image of a point, line, or figure in the X axis, the image has to be reflected over the X axis. The x axis in this situation would be referred to as the axis of reflection.In order to reflect over the x axis, values of y-coordinates are negated while keeping the value of x-coordinate the same.

Environmental isolation the division of biological communities as a result of changes to their ecology or their environment. This is one of the processes that results in speciation because there will be a restriction on the movement of genes between the groups that are now separated, and changes in gene frequencies may happen as a result of local selection or drift until the groups eventually become so different that there are no longer any reproductive pathways between them.The mechanisms of reproductive isolation are a group of behavioural patterns, physiological processes, and evolutionary factors important for speciation.
