Evolution :).

Descent with modification helps to explain anatomical similarities among certain species. The bones of the forelimbs of humans, cats, and bats (you can add in penguins, alligators, and more) are used in different ways but have similar structures.

The best explanation is that these animals have a common ancestor. With new generations, new species emerged by natural selection from different populations, and with this, the bones become better for different tasks.

The forelimbs and other such structures with anatomical similarities due to a common ancestor are called homologous structures.

~~9. genetically speaking, why is it important not to mate with a close relative
Zinaida [17]

Answer:

While linebreeding is less likely to cause problems in the first generation than does inbreeding, over time, linebreeding can reduce the genetic diversity of a population and cause problems related to a too-small gene pool that may include an increased prevalence of genetic disorders and inbreeding depression

In terms of direct or indirect sunlight, what kind of sunlight do we have during wintertime?​
Elena-2011 [213]

Answer: Direct sunlight is more concentrated heat, which tends to be warmer but also covers a smaller surface area. During the winter months, the Sun is lower in the sky and its rays strike the Earth at an oblique angle, otherwise known as indirect sunlight.

Sarah recently learned that O2 is found in the Earth’s water bodies. She was amazed to know the proportion of O2 found in the oc
Mamont248 [21]

It has been found that the rainforests are accountable for about one-third, that is, 28 percent of the oxygen of the Earth, however, the majority of the oxygen, that is, about 70 percent in the atmosphere is generated by the marine plants. The left-over two percent of the oxygen comes from other sources.  

The majority of the oxygen comes from the tiny plants in the ocean known as phytoplankton, which lives near the surface of the water and drifts with the currents. Similarly to plants, they perform the process of photosynthesis, that is, they utilize carbon dioxide and sunlight to prepare food, oxygen is the by-product of photosynthesis.  

However, the concentration of the dissolved oxygen, which the water can hold relies on the salinity and temperature of the water. The cold water can withhold more oxygen in comparison to warm water and fresh water can hold more oxygen in comparison to salt water. So, the warmer and saltier the water is, the less will be the oxygen dissolved in it.
