A dead zone refers to Group of answer choices a) terrestrial areas in which excessive nitrogen fertilizer has essentially burned the soil, preventing plants and microorganisms from living there. b) oligotrophic areas in water bodies that cannot support life due to lack of nutrients. c) an ecosystem that was cleared of all vegetation for slash and burn agriculture. d) hypoxic areas in water bodies that limit marine and aquatic life.
Answer:
The correct answer is d) hypoxic areas in water bodies that limit marine and aquatic life.
Explanation:
A dead zone are oxygen-deprived regions, that is, they are large bodies of water that contain little or no oxygen, both in the depths and near the coasts in the oceans. Aquatic and marine dead zones can be caused by climate change, a product of human activity. When the temperature is high, the water does not have the same density and there is less exchange between the depths of the hydrogen peroxide and the surface water, and these no longer receive oxygen. Marine fauna, not finding the oxygen necessary for their survival, end up suffocating due to the lack of oxygen. They may also have reproductive problems and diseases, making it difficult for them to survive.

Explanation:
which fundamental units are involved in force do step Wise
Force = ma
We know, the unit that the S.I. unit of mass is Kg.
We also know that a = (v - u)/t.
We know that v = d/t and u = d/t and the S.I. unit of t(time) is s.
We know that the S.I. unit of d(displacement) is m.
So, the S.I. unit of v is m/s and the S.I. unit of u is m/s and the S.I. unit of t is s.
So, the S.I. unit of a is m/s×s or m/s²
So, the unit of force is
(unit of m) × (unit of a)
= kg × (m/s²)
= kg.m/s²
=
[tex]kg \: m \: {s}^{ - 2} [/tex]
Or more simply,
F = ma
=> F = m{(v-u)/t}
Putting units,
Newton = kg[{(m/s) - (m/s)}/s]
=> Newton = kg{(m/s)/s}
=> Newton = kg(m/s²)
=> Newton = kg.m/s²
=> Newton = kg.m.(s^-2)
Lactase is an enzyme that is produced in the lining of the intestines. This enzyme helps the body speed up the
breakdown of carbohydrates that are found in dairy products, such as milk, yogurt, and cheese.
Which general function does lactase perform?
Answer:
Regulation of cell processes
Explanation:
Lactase is an enzyme that helps in the breaking down of disaccharide sugar, lactose, found in many foods. It does it by converting the lactose into its component reducing sugars - glucose and galactose. This enzyme is produced by some special cells lining the intestinal walls of humans and forms a kind of chemical barrier known as brush border where foods must pass through before being absorbed. By so doing, foods are screened for the presence of lactose and any lactose is broken down before the foods are given a pass.

Discuss the sensory neurons for vision. What are the two
types of sensory neurons for vision? Where are they located?
What are their functions in the eye? What path does visual
input take AFTER reaching the sensory neurons (be specific,
outlining the entire path to the destination point of the brain)?
Answer:
Olfactory sensory neurons (OSN).
Explanation:
Olfactory sensory neurons (OSN) are the sensory neurons that is responsible for vision. Photoreceptors and olfactory sensory neurons (OSN) are the two types of sensory neurons for vision. Both olfactory sensory neurons (OSN) and photoreceptors is responsible for the receiving of photons and enable us to see things. The right half of the visual field will travel in the left optic tract, while on the other hand, the stimuli from the left half of the visual field will pass through the right optic tract.
Answer: The two types of sensory neurones are the CONES and RODS. Their functions are better outlined below
Explanation:
The CONES and RODS are the sensory neurones ( photoreceptors) of the eye which are located in the retina.
The RODS: They are extremely sensitive and can detect light of very low intensity. They also perceive light in black and white. They, therefore, play an important role in dim light.
The CONES: They function in bright light and are responsible for colour vision.
The path visual input take AFTER reaching the sensory neurons is as follows:
--> the rods and cones are stimulated
--> A pattern of electrical impulses is sent to the brain through the optic nerve which interprets it, drawing on past experience.
The brain tells us that the object is upright and gives us it's real size and distance from the eye. We, therefore, see the object as it actually is, and not as the image formed on the retina.

A solid reactant is placed into a beaker of a warm water. The liquid vigorously bubbles as the solid dissolves into the solution. What will most likely happen if the temperature of the liquid is slightly reduced?
More bubbles will be produced because the solution is becoming more concentrated.
Fewer bubbles will be produced because of fewer collisions of reactant molecules.
The solid will get smaller at a faster rate because of more collisions of reactant molecules.
The solid will get larger at a slower rate because precipitate is coming out of the solution.
Answer: Fewer bubbles will be produced because of fewer collisions of reactant molecules.
Answer:
B: Fewer bubbles will be produced because of fewer collisions of reactant molecules.
If all 15 presynaptic neurons stimulate the post-synaptic neuron at the same time, will an action potential be produced?
Answer:
Yes
Explanation:
If all 15 presynaptic neurons stimulate the post-synaptic neuron at the same time, the action potential will be produced. In a chemical synapse, an action potential in the presynaptic neuron is responsible for the release of a chemical messenger known as neurotransmitter. After this, the neurotransmitter diffuses across the synapse and binds to the postsynaptic cell so we can say that potential can be produced.
