SEE EXPLANATION FOR ANSWER
Explanation:
Eutrophication: An abundance of cyanobacteria (an algal bloom) is caused by an excess amount of nutrients in the water (phosphorus and/or nitrogen) which depletes the water of oxygen which is vital for plant an animal life. Oxygen is crucial for the survival of an organism, so when there is a lack of oxygen, the results can be fatal. That is why when there are reports of algal blooms, there are almost always mentions of an abundance of dead fish, birds, and other water dwelling organisms (these organisms live in the water, drink from it or use it as breeding grounds etc,) Not only that, but algal blooms produce toxins that can make animals and humans fall ill.
Dead zones: As stated previously, harmful algal blooms deprive the water of oxygen.This can lead to the extreme and create dead zones. Dead zones are zones in an aquatic body where the oxygen levels are not sufficient enough to support aquatic life. Hence why there is no life in dead zones because all of the fish either die, or leave.
Both affect the population of native species and the overall wellbeing of the bodies of water.

How do lenses correct vision?
A.) They bend the cornea.
B.) They reflect light away from the retina.
C.) They reflect light towards the retina.
D.) They bend light so that it focuses on the retina.
Answer: D
Explanation:
Glasses correct vision by allowing your eyes to focus light on the correct spot of your retina. The curved frames bend light, and with the right prescription, these frames manipulate the light to reach the correct spot on your retina.
Glasses improve vision by focusing light on the retina. With the right prescription, curved frames bend light to reach the retina.Therefore, option (D) is correct.
What is the function of lenses?Your eyes will be able to focus light on the appropriate portion of your retina when you wear glasses. This will result in improved vision. Light is bent by the curved frames, and when combined with the appropriate prescription, these frames may modify light such that it falls on the retina in the correct location.
Myopia, often known as the inability to see things that are far away, can be rectified with a lens that has a diverging power, which lowers its overall strength. The condition known as hyperopia, in which a person has difficulty seeing things that are up close, can be treated with a lens that converges light in order to boost its power.

The cerebral nuclei are also called the basal nuclei and sometimes are incorrectly called the basal ganglia. Why is this incorrect
It is incorrect to name basal nuclei as basal ganglia because the term 'ganglia' refers to clusters of cell bodies in the peripheral nervous system (PNS). The basal nuclei are a group of subcortical nuclei.
The basal nuclei are a group of subcortical nuclei located deep in the cerebral hemisphere and midbrain.
The basal nuclei can be defined as a region of the brain that is involved in muscle coordination and movement.
The term ganglia make reference to a group of neurons outside of the central nervous system in the peripheral nervous system (PNS).

How does melanoma affect the functions of the skin?
How does jaundice affect the functions of the skin?
Answer:
Melanoma is a type of skin cancer that develops in certain skin cells called melanocytes. These are the cells that make the pigment (melanin) that colors your skin. When exposed to UV radiation, such as sunlight, the melanocytes make more pigment, causing the skin to darken or tan. Melanoma starts in cells in the skin called melanocytes. These cells are in the deep layer of the epidermis between the layer of basal cells.
Jaundice causes the skin and the whites of the eyes to turn yellow. The higher the bilirubin level, the yellower the skin. Severe jaundice usually also causes itching and bile. Bile is fluid secreted by the liver.

When comparing plant cells to animal cells, which organelle is only present in plant cells?(1 point)
mitochondrion

cell wall
Answer:
- cell wall -
Explanation:
The answer is a cell wall because the cell wall in a plant acts as a 'skeletal system'.
So tell yourself does, an animal that already has a skeleton, need the cell wall?!
NO! It dan't! That's why animals don't have the cell walls and plants do.
!!! Hoped that helped !!!
When comparing plant cells to animal cells, cell wall is only present in plant cells. The correct option is D.
What is cell wall?A cell wall is a structural layer found just outside the cell membrane that surrounds some types of cells.
It can be tough, flexible, and rigid at times. It provides structural support and protection to the cell, as well as acting as a filtering mechanism.
The cell wall is made up of a network of cellulose microfibrils and cross-linking glycans embedded in a matrix of pectin polysaccharides that is highly cross-linked. Lignin can be found in secondary cell walls.
It provides a structural framework for plant growth and serves as the plant's first line of defense against pathogens.
The cell wall must also retain some flexibility so that it can be rapidly remodeled in response to developmental, biotic, or abiotic stimuli.
Thus, the correct option is D.
