A family released their pet fish family into a local pond. The fish had no known local population. The impact of the fish on
the ecosystem is not yet known.
Which term would best define the fish added to the pond?
O invasive species
O introduced species
O native species
O symbiotic species

Answers

The term that would best define the fish added to the pond is INTRODUCED species. These species may be harmful to native species.

Introduced species are exotic species which has arrived there by human activity, which may be harmful to native species.

Introduced species may even be harmful to the entire ecosystem because they can break the delicate equilibrium of the ecosystem.

Introduced species may compete with native species for limited resources (e.g., water resources, foods, habitat, etc).

A zombie apocalypse wipes out almost the entire human species before the zombie threat is eliminated. It appears that only a group of 100 people who were at a family reunion on an uninhabited island survived. They returned to the mainland completely unaware of what had happened to everyone. Answer the following questions regarding the few survivors that now begin to rebuild the human population.

Certain traits will have been lost from the gene pool forever. Some may be obvious, like people with red hair and double jointed thumbs. Others will be less obvious, like the ability to process cholesterol or being allergic to peanuts.

a.) Which of the following best describes the mechanism of microevolution that has altered the human gene pool? Explain.

b.) Despite an abundance of habitat, why will it be difficult for the human species to recover in numbers?

c.) A straggler with green eyes stumbles into the last remaining human outpost. The green eye trait did not exist in the outpost before her arrival, but it does now. What is the name of this mechanism of evolution? Explain.

Answers

Answer and Explanation:

A. Hello. You did not enter answer options. However, we can state that mutation, natural selection and genetic drift will be the microevolution mechanisms that will affect the gene pool of these humans. This is because the new environment and the small number of living beings, will make this population completely susceptible to all these evolutionary factors, which will affect, in different ways, the gene frequencies in a population.

B. As the amount of living beings and human beings has become very small, the world will have a low genetic diversity. This will make it difficult for these humans to adapt to the new environment and will make them more susceptible to possible diseases that will arise in this new environment. This will make these humans more fragile and make it harder for them to multiply.

C. The evolution mechanism is the Gene Flow. Gene Flow refers to the exchange of genetic information between individuals in a population, through the donation of gametes that occur in reproductive processes. In this case, we can consider that the individual with green eyes, upon arriving in the community with individuals without green eyes, began to reproduce descendants, who, upon receiving the gametes responsible for green eyes, began to populate this community with this characteristic.

Which statement about US greenhouse gas emissions is supported by the bar graph? Emissions decreased every year between 2005 and 2014. Emissions increased substantially between 2005 and 2014. After peaking in 2007, emissions dropped every year through 2014. After peaking in 2007, emissions went up and down through 2014.

Answers

Countries often have records of gas emissions in their county. The statement about US greenhouse gas emissions is supported by the bar graph is that after peaking in 2007, emissions went up and down through 2014.

Greenhouse gas emissions often takes place due to the activities of human. These activities acts as a catalyst to powerup the greenhouse effect, causing climate changes.

Recorded data of gas emissions has shown that after it peaked in 2007, reduction is said to be of averaged 1.3% per year but the data of U.S. energy-related CO2 emissions in 2019 shows that it was 1.8% greater than in 1990.

Answers

Answer:

trait in which an animal has repeating body parts able to be specialized for different function

Explanation:

Segmentation is a characteristics of many living organisms. Segmentation is referred to as the division of certain body part of an organism into sections. This section is repeated as many times as possible on the animal/plant.

The segment divides the part into specialized units that performs differing functions. The different functions define the organism, hence, segmentation is very important in development.

A scientist hypothesizes that increasing the amount of salt in a body of water will decrease the number of plants that can live in the water. What is the independent variable?
Group of answer choices

Amount of salt

Amount of water

Temperature of the water

Number of plants in the water

Answers

Dependent and Independent variables are regarded as variables in mathematical and statistical modeling and of course in some other aspects.

The independent variable is this case is the amount of salt.

In this kind of scenario, one can think of independent and dependent variables in terms of cause and effect.  An independent variable is the variable we assume to be the cause, while a dependent variable is assumed as the effect. Therefore, with this case, the amount of salt would cause a decrease in the number of plants. While the effect of increasing the amount of salt would be seen in the number of plants.

Mountain chains in northern Europe and West Africa match the Appalachian Mountains in terms of their ages and the sequences of rock layers that make them up. in 3-5 sentences analyze these observations and explain what conclusions can be drawn from them.​

Answers

According to the statement, it can be concluded that the three mountains were formed around the same geological era. Additionally, they have similar layers due to the sedimentation and metamorphization processes.

Since its emergence, the Earth has experienced different physical and chemical phenomena that have influenced changes in it. In the case of the lithosphere and the Earth's crust, they have been influenced by phenomena such as

Volcanism The rock cycle The wind The rainfall Among other

Additionally, geologists have developed methods of studying the crust to know the age and composition of the layers of the Earth's crust. According to this, it can be established that these three layers are of the same age because their composition of layers is studied and the materials and distribution of the layers match, that is, they were formed at the same time.

This coincidence in distribution is explained through the processes of sedimentation of materials and their metamorphization.
