Marine dead zones can form when nutrient run-off causes certain types of algae to grow very quickly and then die off. As dead algae decompose, oxygen is removed from the water. With less oxygen available, fish and other marine animals can die. What would be one practical way to reduce marine dead zones?
A: Add bacteria that are able to eat the fast-growing algae.
B: Harvest marine fish in dead zone areas to reduce oxygen use.
C: Pump oxygen into the water using equipment on fishing vessels.
D: Prevent fertilizer and other wastes from entering rivers and streams.
Answer:
The answer is D.
Explanation:
The practical way for reducing the marine dead zones should be that it prevented the fertilizer.
What is fertilizer?It is the type of natural material or the synthetic origin that should be applied for soiling or to plant tissue for supplying the nutrient of the plants.
It should be distinct from material liming for non-nutrient soil amendments.
Therefore, we can conclude that the option d is correct.

A growling stomach and the stimulation of hunger represent the
A
integumentary system and the endocrine system working together.
B
excretory system and the respiratory system working together.
с
digestive system and the nervous system working together.
D
muscular system and the skeletal system working together.
A growling stomach and the stimulation of hunger represent the digestive system and the nervous system working together. The correct option is c.
What is hunger?Hunger is primarily a biologically induced desire for food, which is required for survival.
Hunger can thus be regarded as a quantifiable biological trait of humans that predicts the willingness to eat as well as the amount of food consumed.
During fasting, the stomach secretes the "hunger hormone" ghrelin to promote food intake.
Ghrelin stimulates appetite by activating its receptor GHSR1a in the brain's hunger sensing neurons, and thus represents a promising avenue for the development of anti-obesity treatments.
A growling stomach and the stimulation of hunger represent the digestive and nervous systems collaborating.
Thus, the correct option is C.

Saponification Select one: a. is a hydrolysis reaction. b. results in the production of triglycerides. c. is used to store energy for later use. d. is a reaction found in plant metabolism.
Answer:
A) hydrolysis reaction
Explanation:
hydrolysis can be explained as a chemical process whereby molecules of water is been added to a substance, and in most reaction the substance and the water molecules split to two part as a result of the addition, and there would be gaining bof hydrogen ion by fragment of the parent molecule. An example of this is saponification.
Saponification can be defined as process of converting oil fat as well as lipid to soap and alcohol through heating using aqueous alkali. Common aqueous alkali that can be used is NaOH. Soap are regarded as salt of fatty acid. Reaction between Ethanoic acid and alcohols is an example of a saponification
Here is soap chemical formula
CH3(CH2)14COO− Na+
Answer: The correct option is A ( is a hydrolysis reaction).
Explanation:
Saponification is the alkaline hydrolysis ( using sodium hydroxide or potassium hydroxide) of fats and oil. It is commonly used for making of soaps which are used for washing and cleaning.
The process is a hydrolysis reaction because there is splitting of ester linkage bonds of triglycerides and addition of hydroxyl group from a hydroxide. This process leads to the production of alkaline salts of long chain fatty acids(soaps). This can be summarised below
Triglycerides (fats&oil) + base( NaOH)
-------> Soap + Alcohol
The crab Lynda tell Ella ya carries a pair of sea anemones on its claw. The crab uses the sea anemones stinging tentacles as protection and the sea an enemy obtain small food particles released by the crab as it feeds which type of symbolic relationship does this best illustrate
Answer: Mutualism

It plays a key role in ecology and is thought to have driven the evolution of much of the diversity currently in existence today.
Gestational diabetes occurs when a pregnant woman has high levels of blood sugar. Cells in the pancreas usually keep blood sugar levels normal, but hormones produced during pregnancy deactivate the cells. After pregnancy, hormone levels return to normal, and so do the pancreas cells. Is this an example of DNA or the environment controlling gene expression? Explain your answer
Answer:
environment controlling gene expression
Explanation:
Gestational diabetes generally occurs in pregnant women. The sugar level in the bloodstream becomes little high than the normal range during pregnancy. But the glucose level returns to normal after child birth.
The pancreas secrets insulin which helps to lower the blood sugar level in the body. But during pregnancy, the placenta releases some of the hormones which dilutes the effect of insulin. This is known as insulin resistance. So now the pancreas secretes more of insulin to overcome this insulin resistance for the body. Now if a woman during pregnancy does secrete more insulin, the glucose level increases in the body and the woman develops gestational diabetes.
Gestational diabetes greatly depends upon obesity and the ethnicity of the women, but a definite genetic link has not been identified.
This it is a result of the environment control gene expression.

6. Name the two ways electric current can be induced using magnetism.
Answer:
Explanation:
We can induce an electric current inside a coil in 2 ways. This is done due to the relative motion of the coil and the magnetic field.
The first and the easier way to do that would be to induce a current on the coil by moving the coil inside a magnetic field.
The second way would be to induce a current on a coil by altering the magnetic field across it.

Meditation is a practice of sitting still and quiet for minutes or even hours. It has been practiced for thousands of years and is even a part of religious practices for some people. Carefully controlled, repeated measurements of brain activity have shown that meditation does increase certain chemicals in the brain and even grows the part of the brain that helps people connect with their current surroundings and activities.
Are claims about the effects of meditation most likely scientific or pseudoscientific?
scientific, because people have been claiming for thousands of years that meditation helps them
scientific, because observations of brain growth and chemicals are made carefully and repeatedly
pseudoscientific, because practices that are related to religion are based on beliefs and are subjective
pseudoscientific, because people have made claims about it but scientific observations have not been made

Answer:
By one week after conception, the multiplying cells have divided into outer cells enclosing a mass of inner cells. The inner cells will become the embryo.
Explanation:
By week one, the outer cells will give the trophoblast, which will later become the placenta, while the inner cells will form the embryoblast, which will become the embryo. Then the inner cells will be in one end, and in the other one, there would be the blastocele, which is a space with fluids. This process takes place in the fallopian tube and is part of the segmentation process.

Suggest what might happen if cells grow and reproduce in an environment where no cholesterol is available.
Cell walls provide support and protection for plant cells and the plasma membrane maintain homeostasis
Explanation:
If cells grow and reproduce in an environment where no cholesterol is available than cell walls provide support and protection for plant cells and the plasma membrane maintain homeostasis.
What is plasma membrane?Cell membrane has been defined as a wall that differentiate and protect the inner structure of the cell from the outer environment. The main function of the cell membrane has to keep away the toxic material out of the cell. The cell membrane contain the channels as well as receptors that gives permission to only selective permeable membrane to enter into the cell.
Cells must maintain homeostasis to survive. To do this cells use various processes. One process keeps the right amount of water inside the cell. A cell takes in the same amount of water as it looses describe that it is maintaining homeostasis by keeping it's water concentration level.
Therefore, If cells grow and reproduce in an environment where no cholesterol is available than cell walls provide support and protection for plant cells and the plasma membrane maintain homeostasis.
