Answer:
No
Explanation:
We now know that sharks have keen vision despite believing they had fragile vision in the past. According to research, sharks may be more than ten times as sensitive to light as humans. Because of how their eyes are built, scientists also think that sharks may be farsighted, meaning they see better at a distance than up close.
What type of power does this structure produce?
Answer:
A-Hydroelectric, hydro means water
Explanation:
The correct answer is A) hydroelectric.
The type of power that this structure produces is hydroelectric.
In times when we need to take care of the environment, hydroelectric power is a good way to produce electricity in large cities.
Also known as hydroelectric energy, this form of renewable energy is "environmentally friendly" in that it uses the power of water -the movement of water- to generate electricity. That is why governments invest in public infrastructure and built dams that help to produce electricity.

In sickle-cell disease, variation in one gene causes red blood cells to bend, or sickle. This means the sickled cells _____.
A)are better at destroying the malaria parasite
B)carry toxic levels of oxygen through the body
C)cannot carry normal levels of oxygen to cells
D)attract larger numbers of the malaria parasite
Answer:
C. cannot carry normal levels of oxygen to the cells
Sickled red blood cells, characteristic of sickle-cell disease, cannot carry normal levels of oxygen to other cells in the body due to their abnormal shape causing them to get stuck in small blood vessels.
Explanation:In sickle-cell disease, the mutation in the hemoglobin gene changes the shape of red blood cells. These cells are no longer round but sickle-shaped, hence the disease name. The right answer to your question is option C: sickled cells cannot carry normal levels of oxygen to cells.
This is because the abnormal shape of these red blood cells makes them rigid and sticky, which can cause them to get stuck in small blood vessels and block blood flow and oxygen to parts of the body. As a result, they can't deliver the usual amount of oxygen which other body cells need to function properly.

how does the presence of similar fossils on different continents support the idea of tectonic plate movement?
when the tectonic plates move the bones are carried from one place to another
The presence of similar fossils on different continents supports the idea of tectonic plate movement because it indicates that these continents were once connected in a landmass known as a supercontinent, and they have since drifted apart due to the movement of tectonic plates.
What are tectonic plates?Tectonic plates are large pieces of the Earth's lithosphere (the outermost solid layer of the Earth) that move and interact with each other. These plates can be thought of as giant puzzle pieces that fit together to form the Earth's surface.
When tectonic plates move, they can carry the continents they support along with them, leading to the separation of previously connected landmasses.
For example, the fossil remains of the freshwater reptile Mesosaurus have been found in both South America and Africa, which suggests that these continents were once connected.
The presence of the same species in two separate locations indicates that they were once a single population and that they were likely separated when the landmass they lived on split apart.
This observation supports the theory of continental drift and plate tectonics, which explain the movement of the Earth's continents over time.

D) undiscovered lands will provide plenty of natural resources
Explanation:
Before the end of the Second World War, there were no studies published in a massive way in order to point out the need to conserve nature for new and future generations. This represented a paradigm of the economy that observed ecology in a profound way, with higher values to human beings than to forests. At the time, the concept of the main economy consisted of the fact that natural resources are not scarce, starting from this concept began to establish conservation methods to preserve mineral resources.
Conservation methods are needed worldwide for several reasons. The factors that highlight the need to support these conservation methods are:

How does aging affect the nervous system?
Answer:neurons die at an increased rate
Explanation:
Did in Health science
While aging brings these changes to the nervous system, it's important to note that the extent and rate of these changes can vary among individuals. Staying mentally and physically active, maintaining a healthy lifestyle, and managing underlying health conditions .
Neuronal Loss: With age, there is a gradual loss of neurons (brain cells), particularly in regions like the hippocampus and prefrontal cortex, which are important for memory and cognitive functions. This neuronal loss can contribute to cognitive decline.
Slower Processing: Aging often leads to a reduction in the speed of information processing, which can result in slower reaction times and difficulty with tasks that require quick thinking and decision-making.
Reduced Neurotransmitter Levels: There is a decline in the levels of certain neurotransmitters, such as dopamine and serotonin, which can affect mood, motivation, and emotional regulation. This can be associated with an increased risk of mood disorders like depression.
Changes in Brain Structure: The brain undergoes structural changes with age, including shrinking in volume and changes in the distribution of white and gray matter. These structural changes can impact cognitive function and memory.
Decreased Plasticity: Neuroplasticity, the brain's ability to adapt and learn, decreases with age. This can make it more challenging to acquire new skills or adapt to new situations.
Impaired Sensory Functions: Aging often leads to diminished sensory functions, such as reduced vision and hearing, which can impact perception and communication.
Increased Risk of Neurological Conditions: The risk of neurological conditions like Alzheimer's disease and Parkinson's disease increases with age. These conditions can have profound effects on cognitive and motor functions.
Decline in Motor Function: The nervous system's control over motor functions can be affected by aging, resulting in decreased coordination and balance.
Vascular Changes: Aging can lead to changes in blood vessels, including reduced blood flow to the brain. This can contribute to cognitive impairment and an increased risk of strokes.

food
Answer:
Carbondioxide and water
Explanation:
During respiration food molecules are broken down to release energy. During this process oxygen is required and not formed but Carbondioxide and water is liberated as byproduct. So the closest answers are Carbondioxide and water
During respiration, consumers such as animals release the carbon dioxide gas into atmosphere. Thus, the correct option is C.
What is Respiration?Respiration can be defined as a metabolic process wherein, the different living cells of an organism can obtain energy in the form of ATP(Adenosine triphosphate) by taking in the oxygen gas and liberating carbon dioxide gas from the oxidation of complex organic substances into the atmosphere.
Carbon dioxide is the main gas or the by-product which is released back into the atmosphere during the respiration of consumers, which then breaks down to glucose molecule and other complex organic compounds and gets converted into the carbon back to carbon dioxide for reuse by the producers.
Therefore, the correct option is C.
