Are there any parts of the human body that get oxygen directly from the air and not from the blood? Are there nuclear reactions going on in our bodies?​

Answers

Answer 1

Answer:

The cornea is the only part of a human body that has no blood supply; it gets oxygen directly through the air. The cornea is the fastest healing tissue in the human body, thus, most corneal abrasions will heal within 24-36 hours.

Nuclear reactions do indeed occur in the human body, but the body does not use them.

What are ocean waves?

Ocean waves are the result of the interaction between the ocean and the wind. They are the most visible and powerful manifestations of the Earth's oceans. Ocean waves vary in size, shape, and speed, depending on the wind's strength, duration, and direction. They can range from small ripples to massive swells and can travel thousands of miles before breaking on shorelines.

The energy of ocean waves is harnessed for various purposes, such as surfing, fishing, and generating electricity through wave energy converters. However, ocean waves can also be destructive, causing erosion and flooding in coastal areas during storms.

Ocean waves play a crucial role in regulating the Earth's climate by transferring heat and energy from the tropics to the poles. They also help distribute nutrients and oxygen to marine life, and their movement influences the ocean's circulation patterns.

Algae are small photosynthetic organisms found in aquatic ecosystems. Their cells produce a kind of oil. Scientists learned how to extract the oil to create fuel, which can be used in place of fossil fuels. Scientists think algae can produce 60 times more oil per acre than plants, like corn, that are commonly used to produce biofuel.

To produce algae oil, very large ponds were built for growing algae. However, scientists soon made two discoveries.
As the algae grew, it formed layers at the pond surface. These layers crowded and shaded one another.
Many insects and other consumers frequently entered the ponds.
Based on the two discoveries, what would likely be a problem for algae oil production?
A.
Crowding reduces access to food, so it makes algae less able to take in sugar and produce oil.
B.
Insects feed on algae, so all of the energy stored in algae oil is converted back into light energy.
C.
Consumers feed on algae, so the energy stored in algae oil is permanently lost from the environment.
D.
Shading reduces access to sunlight, so algae produce less sugar and are less able to store energy.

Answer:

How did green algae come about ​

Answers

Answer:

Green algae grow at the edges of a glacial lake in Wales. Hundreds of millions of years ago, similar algae adapted to survive temporarily outside of the water may have kicked off the evolution of green land plants.

Algae didn't always hang out in the seas, but one fateful day, about a billion years ago, a simple bacterial cell swallowed a cyanobacteria cell, writes Ed Yong at The Atlantic. This chance occurrence allowed the bacteria to produce energy from the sun, a process known as photosynthesis.

Carter and Anton had convinced their father to help them build a tree house last year, but snow covered the ground before they were able to get started.Through much anticipation, Carter and Anton had waited and prepared, and they were ecstatic that it was finally time to dive into their project. First, they had to go to the lumber yard with their father and purchase the wood. They spent an entire weekend measuring, cutting, and assembling the wood to create the floor, walls, and roof; it was very exciting to see the lumber transform into a small house. Every evening, Carter, Anton, and their father would spend several hours nailing pieces of wood together until the tree house was finally complete. Then they went to the paint store, where Carter and Anton took nearly two hours to agree on the color lime green. Painting their tree house sounded more fun that it was; the sanding, priming, and rolling paint on each section of the house was both challenging and time consuming. After more than a month of hard work and dedication, the tree house was finally complete.Which sentence should be added to introduce the narrative? A. Carter and Anton were very happy with how their tree house turned out. B. The two brothers were excited to shop for supplies for their treehouse with their father. C.
