US clean water act as a prompted the developers to install stormwater management systems to handle the movement of polluted water.

The Clean Water Act (CWA) establishes the fundamental framework for controlling pollution discharges into American waters and setting quality criteria for surface waters.

In 1972, the US Clean Water Act was adopted. The Act's principal goal was to control and minimize the entry of pollutants into water bodies. This was done to make the water bodies cleaner, clearer, and more suitable for usage by the general public and the abundant life forms that were already present.

In order to handle the removal of contaminated water from the water bodies, the developers decided to install stormwater management systems.

Answer:

C: replenishable but not renewable

Explanation:

Options:

A. They depend on the myelination of nerve axons

B. They include EPSPs and IPSPs

C. They are changes in the membrane potential of the postsynaptic terminal of a chemical synapse

D. They are caused by neurotransmitters

Answer:

An additional neuron known as a fascilitator is triggered when the postsynaptic neuron receives an unconditioned stimulation. The presynaptic neuron then responds to this cell, leading to sensitization.

When the neurotransmitter separates from its receptor, postsynaptic potentials start to be terminated. After that, the receptor is free to resume its original structural form. The receptor will now reopen ion channels that were opened when the neurotransmitter was attached to it.

Answer:

B

Explanation:

Did the assignment

Explanation:

The phenotypes and genotypes of the progeny can be determined by a dihybrid cross of the parents.

The heterozygous male will have the genotype 'SSww' and the heterozygous female will have the genotype 'ssWW'.

When crossed, the F1 offsprings will have a hybrid genotype of 'SsWw'. These offsprings are heterozygous with spotted skin and wooly hair.

On self-crossing of the F1 hybrids, we find four different combinations of the alleles- SW, Sw, SW and sw. The probability of getting each of these combinations is 1/4.

Hence, the probability of any dihybrid type is 1 out of the 16 possible genotypes. Using Punnet square, we find

9 SSWW: 3 SSww: 3 ssWW : 1 ssww

This is the phenotypic ratio of the offsprings.

The ratio of the possible genotypes will be 1:2:1:2:4:2:1:2:1.

1. Bees, flies, wasps, butterflies, and moths are significant insect pollinators. Moths are drawn to white flowers that are open at night, but bees and butterflies are drawn to brilliantly colored blooms with powerful scents that are open during the day.

The act of moving pollen grains from an anther to a flower's stigma is called pollination. Flowers that are pollinated by insects typically generate a sweet nectar that the insects visit to consume. If a flower is self-pollinating, fertilization occurs when pollen stock from an insect contacts the stigma of the bloom. If the bug is bisexual, it will fly to another bloom and disperse the pollen.

2. Most flowers advertise themselves by being brightly colored and perched on long stems so they wave in the air and are closer to where insects are flying, as opposed to on the ground, where they would otherwise be. A flower's petal sizes and shapes, in addition to color, can draw insects.

3. Flowers draw insects because of their aroma or vibrantly colored petals. Nectar is a delicious liquid that many flowers generate that is consumed by insects. The female part of the flower is the carpel.

Answer 2. Flowers that are pollinated by insects have characteristics that enable insects, birds, or other animals to pollinate them while consuming the nectar. When an insect brushes by the stigma of a flower, whether it is the same bloom or another, pollen grains will adhere to the insect's outer layer and stick to the flower's stigma, pollinating the flower. When the two seˣ cells combine, fertilization occurs, the ovule develops into a seed, and the ovary becomes a fruit. The pollen grain then grows a pollen tube down the style to reach the ovary, which contains the ovules.

Engineer Nikolaus August Otto developed the first four-stroke internal combustion engine and established the Otto cycle, a well-known theoretical cycle that governs the operation of explosive engines.

Otto's engine outperformed the steam engine in use at the time in a number of ways. One of them is their light weight, as steam engines need large water reservoirs and fuel to burn in order to heat the water, which in this case would be charcoal or firewood. In addition to being light, the internal combustion engine consumed little fuel, even benzene. Another factor was Otto cycle internal combustion engines' power, which also outperformed steam engines in terms of size ratio.

These benefits put pressure on the automotive sector to build vehicles with this kind of technology. Blacksmiths were compelled to learn new skills in order to use this new technology.

Answer:

Explanation:

Both Groundwater and surface water are largely replenished by rain water.

The scenario described provides evidence for option D: Environmental change can impact the quality of life for living organisms.

The passage explains how acid precipitation, commonly known as acid rain, can dissolve aluminum from soil. This dissolved aluminum can then flow into lakes, resulting in contamination of the water.

High concentrations of aluminum in lakes can be fatal to many forms of aquatic life. This evidence supports the concept that environmental change can have a detrimental impact on living organisms.

Option A is incorrect because the passage does not suggest that environmental change always has a negative impact on organisms. While the scenario highlights a negative consequence of acid rain on aquatic life, it does not generalize this impact to all environmental changes.

Option B is also incorrect because the passage does not claim that acid rain is the most important environmental problem to address. It solely focuses on the specific issue of aluminum contamination in lakes due to acid rain.

Option C is incorrect because the passage does not state that acid rain is the leading cause of death to fish in lakes. It highlights the detrimental effect of high aluminum concentrations, but it does not compare it to other potential causes of fish death in lakes.

Therefore, the most appropriate concept supported by the scenario is option D, which acknowledges that environmental change can impact the quality of life for living organisms based on the example of aluminum contamination in lakes due to acid precipitation.
