The nonnative organisms are introduced to new aquatic ecosystems in option "D" which is migration.
What is an aquatic ecosystem?An aquatic ecosystem is an ecosystem in and encircling a body of water, indifferent to land-based terrestrial ecosystems.
Aquatic ecosystems have communities of organisms that are dependent on each other and on their environment.
Thus, migration is not a way that nonnative organisms are presented to new aquatic ecosystems related to trade.

Describe two effects that ingesting microbeads has on aquatic organisms.
Answer:
micro-beads can cause blockages in the digestive tracts of aquatic organisms.
This can prevent digestion of food hence the organism will eventually die of starvation.micro-beads can increase organic matter in a pond hence killing the aquatic organisms present.
This increases the number of decomposers which grow rapidly and use a great deal of oxygen during their growth and lead to depletion of oxygen as the decomposition process occurs. A lack of oxygen can kill aquatic organisms.Explanation:
You sample 1,000 individuals from a large population for the mn blood group, which can easily be measured since co-dominance is involved (i.e., you can detect the heterozygotes). they are typed accordingly:
Co-dominance in the mn blood group means that both allele characteristics are expressed in the organism.
What is co-dominance?Co-dominance is a form of inheritance whereby two or more alleles for a given trait are both dominant such that when they both appear in an organism, the phenotype of that organism reflects the characteristic of both traits.
Co-dominance is usually seen in blood group typing.
In blood group typing, there are two alleles that A and B which are both dominant. When both alleles are present, the blood group is AB and the phenotype of the organism is a result of the properties of both alleles, thus allele A and B are said to be co-dominant.
Therefore, co-dominance in the mn blood group means that both allele characteristic are expressed in the organism.

The phase of the moon where only a very small part of the lit surface is seen from the earth is quarter. Thus, option B is correct.
What is the phase of the moon ?Lunar phase is the phase of moon which is viewed from the earth, the lunar phase is also known as moon phase is a shape of moon's directly sunlit portion and it can be expressed quantitatively.The current moon phase for today is the new moon phase.
The moon is known as earth's only natural satellite and combinedly with earth it forms the earth-moon satellite system.
The size of moon is one quarter of earth in diameter. It is fifth largest satellite in the solar system.

The physical appearance of an organism is known as its
A. genotype
B. phenotype
C. allele
D. testcross
Answer:
B.Phenotype
Explanation:
The term "phenotype" refers to the observable physical properties of an organism; these include the organism's appearance, development, and behavior. An organism's phenotype is determined by its genotype, which is the set of genes the organism carries, as well as by environmental influences upon these genes.

3. Explain how this experiment demonstrated natural selection.
Based on the nature of their environment, natural selection will favor the bear type that is better suited to its environment.
What is natural selection?Natural selection is a process of evolution in which organisms which are better suited to their environment are selected for survival.
In the bear population, natural selection will favor each bear type that is better suited to its environment.
In cold and icy environments, the light bears are better suited to their environment and are naturally selected for survival.
In temperate and warm climates, dark bears are better suited to their environment and are naturally selected for survival.
Therefore, natural selection will favor the bear type that is better suited to its environment.

color goes with which type of bear.)
Okay, this is REALLY simple. Just make a graph with the info given to you.
2. Summarize the trends you see in each population from each generation.
a. Dark bears— Dark Bears with their arms up always had double to amount of the Dark bears with their arms down, and past Generation 3 the Dark Bears had more numbers than the Light Bears
b. Light bears— Light Bears start off with only arms down, and when arms up bears are introduced, they are more common/prevalent for the majority of the generations, having usually twice as much as the bears with the arms down.
3. Explain how this experiment demonstrated natural selection.
This experiment shows natural selection by hosting events in which certain bears are put more at a risk than other bears, such as environment changes favoring dark bears, or bears with their arms up.
4. If the environmental situation changes, is it possible for a population to be restored?
Via adaptations, it is completely possible for a bears population to thrive again, but perhaps not with the same characteristics.
5. How can natural selection help explain how a population becomes extinct?
As the environment changes, it may favor a species less and less, which leads to their decline, if they are unable to change with the times and adapt, the species will go extinct as it is no longer fit in its environment.
6. Which generations saw a population altering incident? Use your imagination to invent a possible environmental incident that could have caused this shift in populations.
The Light Bears faced a decline, and most bears with their Arms Down faced a decline too. Light bears could be explained via environmental factors, such as their original habitat being snowy, and without the snow they're more visible given their lighter colors. Arms down could simply be a dominants v recessive trait
7. How can environment impact a particular population of a species?
If a certain species is not fit for the changes made in an environment, it could result in either their extinction, or a mutations/adaptations so that the species can continue to thrive.
8. What are some natural reasons that animals in a population might die?
Competition, not enough resources, environmental changes.
9. What are some man-made reasons that animals in a population might die?
Things such as deforestation, overhunting, and introducing invasive nonnative species.
10. What are some ways that man has helped animals maintain their populations?
Protecting endangered species, rehabilitating injured animals, making animal reservations, etc.

Peat is a mixture of partially decomposed plant and animal material found in waterlogged, acidic, anaerobic environments. people debate whether peat is a fossil
fuel. to be considered a fossil fuel, a material must be of biologic origin, be used as a source of energy, and replenish on a time scale greater than human
lifetimes. peat reserves have declined over time. however, peat harvesters claim that a restoration process
can make peat a renewable resource and allow it to
be classified as a biofuel. the restoration process is outlined in the table.

Based on the data from the restoration process of peat, it can be concluded that peat is a fossil fuel because the total restoration time is lengthy.
What are fossil fuels?Fossil fuels are fuels produced from the remains of dead plants and animals which decomposed under intense heat and pressure over a long period of time.
Fossil fuels are non-renewable energy sources because their time of replenishment is longer than a human lifetime.
Examples of fossil fuels include:
