Explain the general distribution of life in aquatic systems as a function of chemistry, geography, light, depth, salinity, and temperature.
Different types of organisms can exist in a variety of aquatic environments due to the fact that they can vary significantly from place to place and that organisms within each water system will have evolved to adapt to their specific environment.
How does light affect aquatic life?Sunlight plays a vital role in the ocean’s ecosystem. First, sunlight enters the water column, warms it, creates currents, and is then absorbed by phosphorous-rich phytoplanktons. Phytoplanktons use the energy captured by phototrophs (pigments like chlorophylls) to convert water and nutrients into organic matter.
Light availability determines the types of organisms that can live in a particular part of an aquatic environment. The deeper the water depth, the less light it can penetrate until there is no light at all.
The salinity of water affects its density which in turn affects the movement of ocean currents. It may also affect marine life which needs to regulate the intake of salt water. There is a relationship between salinity, temperature, and water density. Therefore, any change in temperature or water density will affect the salinity of the water in the area.
Water chemistry parameters (pH, dissolved organic carbon, and hardness) play a role in metal toxicity by influencing the bioavailability of aquatic species of metals in water.

Garlic mustard has been introduced to the beetles ecosystem. Describe what would happen to the beetles population as a result and explain why.
Answer:
It would collapse
Explanation:
Garlic mustard also produces root exudates that inhibit the growth of important soil fungi and leaf chemicals that kill native butterfly larvae that feed on the plant
In addition, invertebrates and other consumers that rely on these natural plant species for food are harmed by the spread of this invasive "weed". Garlic mustard also produces root exudates that inhibit the growth of important soil fungi and leaf chemicals that kill native butterfly larvae that feed on the plan
Garlic mustard is an invasive plant species that is known to negatively impact native plant populations in ecosystems.
What is invasive plant?An invasive plant is a non-native plant species that is introduced to an ecosystem and has the ability to spread and negatively impact native plant and animal populations.
Garlic mustard is known to release chemicals that inhibit the growth of other plant species, including some that the beetles may rely on for food.
This could lead to a reduction in food availability for the beetles, which may cause a decline in their population.
Additionally, if the beetles are not adapted to feeding on garlic mustard, they may not be able to digest or utilize the plant efficiently, leading to further declines in population.
Thus, the impact of garlic mustard on the beetle population will depend on the specific beetle species and the extent to which they rely on native plant species for food.

Which two words describe the grass in this food chain?
A. Autotroph, primary consumer
B. Heterotroph, producer
C. Heterotroph, primary consumer
D. Autotroph, producer
Answer: Autotroph, producer
Explanation: The grass gets eaten by primary consumer starting the food chain
In a food chain, the grass is referred to as an autotroph and producer. Therefore, option D is correct.
What are autotrophs?An organism is referred to as an autotroph or primary producer when it uses carbon from simple substances like carbon dioxide to create complex organic compounds. These creatures often obtain their energy from inorganic chemical reactions or light.
Both plants like blue-green algae and microorganisms like cyanobacteria are assumed to be autotrophs. Most plants are autotrophs because they create their own food through photosynthesis. But there are always exceptions to the norm. Some plants are parasitic and non-photosynthetic, getting their nutrition from a host.
Thus, the grass in a food chain is described as autotroph and producer. Therefore, option D is correct.

How does reducing gene flow cause speciation?
A. it increases fossilization
B. it creates patches of favorable habit
C. it increases gene flow
D. it allows populations to become genetically different
Gene flow cause speciation because it allows populations to become genetically different.
What is speciation?Speciation is the process of creating a new plant or animal species. When a group within a species separates from other members of the species and develops its own distinct feature known as speciation.what is gene flow?Gene flow refers to the movement of alleles (genes) from one population to another across geographical boundaries. Gene flow is the movement of genes into and out of a population.Individual creatures may migrate to new populations and reproduce, or gametes may move .for example as a consequence of pollen transfer among plants.How does gene flow affect speciation?By recombining the gene pools of the groups and thereby mending the emerging differences in genetic variation that would have led to full speciation.
The establishment of daughter species, gene flow strongly opposes speciation.

Which is an advantage of a natural gas burning power plant over an oil burning power plant
Answer:
Natural gas is a fossil fuel that burns relatively cleanly.
When natural gas is burned for energy, it produces fewer air pollutants and carbon dioxide (CO2) than when coal or petroleum products are burned to produce the same amount of energy.
An advantage of a natural gas-burning power plant over an oil-burning power plant is that the burning of natural gas produces no or less amount of air pollution as compared to that of oil or coal burning.
What is Natural gas?Natural gas may be defined as a type of non-renewable energy resource that typically synthesizes deep under the earth's surface. This gas is a mixture of hydrocarbons that primarily consists of methane.
The burning of natural gas generally releases very less or no amount of air pollutants like carbon dioxide, and other greenhouse gases which are harmful to all living entities. Natural gas is typically cleaner, environment friendly, and burned for energy.
But when coal, oil, or other petroleum products are burned, they release huge amounts of pollutants into the environment and make it toxic for all.
Therefore, it is well described above.

A gardener crosses tall true–breeding pea plants with short true–breeding ones. Tall plants are dominant to short ones. He collects the seeds to grow F1 plants and then allows them to self–pollinate to form an F2 generation. Which of the following describes the traits of the offspring correctly?
A.
Three–fourths of the F1 and one–half of the F2 plants will be tall.
B.
All of the F1 and three–fourths of the F2 plants will be tall.
C.
Three–fourths of the F1 and all of the F2 plants will be tall.
Answer:
Explanation:
Let T = tall allele (dominant), t = short allele
True breeds are homo-zygous.
So the gardener is crossing TT with tt, with the resulting genotype of F1 all equal to Tt, i.e. all Tall hetero-zygous.
When the F1 pea plants are allowed to self-polinate, F2 results in Tt crossing with Tt, with the genotypes TT, Tt, tT and tt, and phenotypes 75% tall and 25% short, tall being dominant.

Answer:
In the presence of lidocaine, the action potential was NOT affected at R1 because lidocaine was applied downstream of R1
Explanation:
Lidocaine is an anesthetic that has the power to neutralize neuromal membranes. This anesthetic power allows the ionic fluxes capable of stimulating impulses to be diffused and this allows a dormancy to be achieved. However, when lidocaine is applied downstream to a molecule or structure, the action potential of that structure or molecule is not affected and it may continue to receive impulses.
