A lake has begun to degrade due to an increase in human activity and urbanization. The main cause of this degradation is that
the oxygen carrying capacity of the water has decreased due to an increase in the discharge of organic substances (especially
phosphates) in the lake due to fertilizer runoff from local farms. This increase in organic substances has allowed aquatic plants,
including algae, in the lake to grow at an increased rate. As these aquatic plants die, excessive oxygen is used in the
decomposition process, which leads to oxygen deprivation and fish kills. This results in reduced animal populations in the lake,
and the decomposition process releases more phosphates back into the water to feed even more plant growth. This dramatic
increase in plant growth is called eutrophication and can make water unfit for human consumption
A scientist wants to come up with a solution to help minimize eutrophication as a way to maintain the lake's natural ecosystem
without eliminating any of the lake's native populations. Which of the following would be the best solution for the scientist to
implement?
OA. creating buffer strips around the lake using land vegetation to trap fertilizer runoff and prevent it from reaching the
water
OB. spraying clay on the aquatic plants so that they sink to the bottom of the lake to decompose
OC. asking the farmers in the area to only use fertilizer on their crops when it is raining or windy outside
OD. treating all runoff with metal complexes that are poisonous to algae populations

Answer 1

Answer:

The answer is b

Explanation:

because i did the test and i got the answer right

Answer 2

The correct option is A. creating buffer strips around the lake using land vegetation to trap fertilizer runoff and prevent it from reaching the water.

What is buffer Strips?

A buffer strip refers to an area of land maintained in permanent vegetation that helps to control air quality, soil quality, and water quality, along with other environmental problems, dealing primarily on land that is used in agriculture.

Buffer strips trap sediment, and enhance filtration of discharge organic substances  as phosphates and pesticides by slowing down surface runoff that could enter the local surface waters (here, lake).

Thus, buffer strips can be used prevent discharge of organic substances  into the lake that lead to increase in biological oxygen demand  water affecting  the stable lake ecosystem.

What are exoskeleton?

In comparison to the internal skeleton of a human, an exoskeleton is an external skeleton that endorses and safeguards the body of an animal.

Some of the larger exoskeletons are referred to as "shells" in popular parlance.

The exoskeleton is made up of two layers: a thin outer nutrient layer called the epicuticle and a tough outer inner chitin-protein layer called the procuticle.

The epicuticle of most terrestrial arthropods, such as insects and spiders, contains waxes that aid in reducing evaporative water loss.

Hair and fur are molecularly indistinguishable because they are made of the same keratin.

Thus, the correct option is D.

Answers

Answer: The body systems that are involved are:

--> Nervous System and

--> muscular system.

Explanation:

The body is made up of different organ systems which usually works together to bring about proper functioning of the living organism. Examples of the body systems includes:

--> The nervous system: This system enables the animal to detect and respond to stimuli rapidly.

--> The muscular system: This system enables the organism to move from one location to another.

Both the nervous system and the muscular system work together to bring about coordination of activities. When you step on a tack and jeck away, sensory receptors detects stimuli from the external environment and pass the information received as an electrical impulses to the brain through the nerve fibres. The information is processed in the central processing region which is the brain.

The effectors such as the muscles goes into action upon receiving nerve impulses from the brain. Such actions includes muscular contractions which helps you to pick up the tack and put it on your desk.

MonoHybrid Genetics:
Most genetic traits have a stronger, dominant allele and a weaker, recessive allele. In an
individual with a heterozygous genotype, the dominant allele shows up in the offspring and the
recessive allele gets covered up and doesn't show; we call this complete dominance.
However, some alleles don't completely dominate others. In fact, some heterozygous
genotypes allow both alleles to partially show by blending together how they are expressed; this is
called incomplete dominance. Other heterozygous genotypes allow both alleles to be completely
expressed at the same time like spots or stripes; this is called codominance. Examples of each are
listed below.
Write what each type would be if they were heterozygous.

Answers

Answer:

Heat

Explanation:

 Contact metamorphism happens when hot magma or lava comes into contact with rocks, causing a small area to change into a metamorphic rock. Contact metamorphism will be present on the outside edges of igneous intrusions.

Heat and/or pressure causes the metamorphism of an igneous rock into a metamorphic rock.

What is metamorphic rock?

Metamorphic rocks refer to as some other type of rock, but have been substantially changed from their original igneous, sedimentary form. Metamorphic rocks formed when rocks are subjected to high heat, high pressure, hot mineral fluids or, more commonly, some combination of these factors.

Contact metamorphism occurs in rock exposed to high temperature and low pressure, as might happen when hot magma invades into or lava flows over pre-existing protolith. This combination of high temperature and low pressure generates numerous metamorphic facies.
