Answer:
A) The cornea is the transparent outer covering of the eye,The lens is a curved structure in the eye that that bends light and focuses it for the retina to help you see images clearly.The lens works together with the cornea to focus light correctly on the retina. When light hits the retina (a light-sensitive layer of tissue at the back of the eye), special cells called photoreceptors turn the light into electrical signals.
B)The iris is the part of the eye that makes up your eye color. A circular muscle with a hole in the middle.The iris controls the amount of light that enters the eye by opening and closing the pupil. The iris uses muscles to change the size of the pupil. These muscles can control the amount of light entering the eye by making the pupil larger or smaller.
C)Rod cells are highly sensitive to light and function in nightvision, whereas cone cells are capable of detecting a wide spectrum of light photons and are responsible for colour vision.

What happens when carbon dioxide from the atmosphere dissolves in seawater.
Answer:
When carbon dioxide dissolves in seawater, most of it becomes bicarbonate ions and hydrogen ions. This increase in hydrogen ions is what decreases the pH. In addition, some of the hydrogen combines with carbonate to form more bicarbonate, decreasing the concentration of carbonate in seawater.
When carbon dioxide dissolves in seawater, most of it becomes bicarbonate ions and hydrogen ions. This increase in hydrogen ions is what decreases the pH.
When carbon dioxide dissolves from the air into the ocean?The ocean takes up carbon dioxide through photosynthesis by plant-like organisms carbon dioxide dissolves in water. It reacts with seawater, creating carbonic acid.
Thus, it becomes bicarbonate ions and hydrogen ions. This increase in hydrogen ions is what decreases the pH.

Select all the correct answers. which two examples may be converted into fossil fuel after being buried under pressure for a long period of time? used cans plants animal waste electronic waste chemicals
Fossil fuel is carbon containing material formed by underground remains of dead plants and animals, including human extract and can be burned as fuels.
What is the procedure of changing fossils into fuel?These fuels are found in earth's crust and contains carbon that burns to produce energy. Its examples can include coal, petroleum, oil, etc.
These fuels are created when the buried plants and animals are subjected to intense heat and pressure. It contains carbon and hydrogen, which burns to produce energy.
Thus, here plants and animal waste can be converted into fossils fuels, while electronic waste and used cans cannot.

What is the name of the microtubule-organizing center found in animal cells that is present during all phases of the cell cycle?
Answer:
It is called the Centrosome
Explanation:
The Centrosome is known as the main microtubule organizing center of animal cells, the Centrosome participates in the organization of the microtubule network within a cell. It's formed with two centrioles surrounded by a matrix of proteins called pericentriolar material.
The cell cycle includes various phases. The microtubule-organizing center found in animal cells is present during all phases of the cell cycle are centrosomes.
What is a centrosome?A centrosome is a cellular organelle which is involved in the process of cell division.
Before cell division, the centrosome duplicates, as division begins, the two centrosomes starts moving to opposite ends of the cell.
It is the main microtubule-organizing center (MTOC) of animal cell. It is also a regulator of cell cycle progression.
Thus, the centrosome is the microtubule-organizing center found in animal cells that is present during all phases of the cell cycle.

Pls answer!!
a) Based on this information and the food chain below, what are the implications of
not taking immediate steps to reduce CO2 emissions in the atmosphere? (2 points)
algae → snails — crabs — salmon → man
b) Because killer whales are at the top of many food chains, it may seem as if they
are not at risk of starving if seals die off. Why is this not necessarily true? (2 points)
Answer:
a) Higher carbon dioxide levels means a rapid growth of Algae, especially toxic blue-green algae that can float to the surface of the water. This growing amount of Algae will expand across the ocean and clutter it. Harmful algal blooms can be harmful to aquatic life, as some produce toxins that can make animals sick, while others can die off in large quantities and deplete oxygen in the water when they decompose. Snails, specifically aqaurium snails, crabs, and salmon do feed on Algae, which could control it to a degree. However, as the ocean becomes more acidic, it could dissolve the shells of crabs and snails, which will cause them to cook in the sun, and therefore die out. As for salmon, studies showed that high CO2 concentrations disturb fish acid-balance, induce stress response, increase nephrocalcinosis incidence, energy metabolism, and feed conversion ratio, and reduces body condition factor, feed intake, and growth. Fish in this condition are very vunerable to dying despite food being all around them. Additionally, fish in those conditions are not suitable for consumption, which means less food for mankind.
b) This is not true. Although they eat sharks, whales, and dolphins, that is just occasional. Seals are their primary meal. As the killer whale is a consumer, it cannot provide food/energy for itself, therefore relying on organisms below it on the food chain. The killer whale predominately consumes seals, being it’s only large predator, killer whales are crucial to the stabilisation of seal population.
