Answer:
Human impact on coral reefs is significant. ... Damaging activities include coral mining, pollution (organic and non-organic), overfishing, blast fishing, the digging of canals and access into islands and bays. Other dangers include disease, destructive fishing practices and warming oceans.Factors that affect coral reefs include the ocean's role as a carbon dioxide sink, atmospheric changes, ultraviolet light, ocean acidification, viruses, impacts of dust storms carrying agents to far-flung reefs, pollutants, algal blooms and others. Reefs are threatened well beyond coastal areas. Climate change, such as warming temperatures, causes coral bleaching, which if severe kills the coral.
In 2008, a worldwide study estimated that 19% of the existing area of coral reefs has already been lost, and that a further 17% is likely to be lost over the subsequent 10–20 years.[3] Only 46% of the world's reefs could be currently regarded as in good health [3] and about 60% of the world's reefs may be at risk due to destructive, human-related activities. The threat to the health of reefs is particularly strong in Southeast Asia, where 80% of reefs are endangered. By the 2030s, 90% of reefs are expected to be at risk from both human activities and climate change; by 2050, it is predicted that all coral reefs will be in danger.
The set of species derived from one common ancestor.
To build phylogenetic trees, a variety of data can be employed, including genetic information, mitochondrial DNA sequences, ribosomal RNA genes, and any relevant genes, as well as morphological information such as structural characteristics, organ kinds, and specific skeletal arrangements
<h3>What is a Phylogenetic tree ?</h3>
A phylogenetic tree, also called a phylogeny, is a diagram that shows the evolutionary branches from which various species, creatures, or genes have descended from one another.
- A phylogenetic tree can be used to track a species' evolutionary history back via the tree's branches and find their common ancestors along the way.
- A lineage may preserve some of its ancestors' characteristics over time, but it will also change over time to accommodate the environment.

Answer;
C. 100 - 125 mg/dL
A person with prediabetes has a fasting blood glucose level of 100-125 mg/dL.
Explanation;
-A fasting blood sugar level below 100 milligrams per deciliter (mg/dL) — 5.6 millimoles per liter (mmol/L) — is considered normal.
-A fasting blood sugar level from 100 to 125 mg/dL (5.6 to 7.0 mmol/L) is considered prediabetes. This result is sometimes called impaired fasting glucose. A fasting blood sugar level of 126 mg/dL (7.0 mmol/L) or higher indicates type 2 diabetes.
Binocular vision, the ability to focus both eyes on the same object at the same time, usually does not develop until 4-5 months of age.
Binocular vision is the type of vision in which both the eyes look in the same direction to form a 3-D image of the object. One single image is formed by both the eyes. When any disorder appears regarding the binocular vision, the core reason is the misalignment of both the eyes.
Eyes are the organs of vision. They are present in a pair embedded in a socket like region on the skeleton below the forehead. The image is formed at the retina of the eye. The image formed is an upside down image.
