Based on this phylogeny, the archosaurs are a ______. Multiple choice question. monophyletic group polyphyletic group paraphyletic group
Based upon what we know of phylogeny, we can confirm that archosaurs are considered to be a monophyletic grouping.
Placing a species into the monophyletic grouping indicates that the species in question is among a group of species that all derive from a common ancestor. Therefore, a monophyletic group contains a common ancestor and all of its direct descendants. Studies have shown this to be the case for the archosaurs.

Iconic Maine species such as moose, Canada lynx, loons, boreal chickadees, eastern brook trout, saltmarsh sparrows and Atlantic puffins are under stress from climate change. A mutation in the boreal chickadees increases the ability of the bird to catch and eat certain insects. Which factor might determine whether the frequency of the new allele will increase?
A)whether the mutation allows the chickadees better access to food sources than those without it
B)whether those with the mutation make better mates
C)whether the mutation is dominant or recessive
D)whether the mutation is random
Answer:
A) Whether the mutation allows the chickadees better access to food sources than those without it
Explanation: USATestprep
The factor that may determine the frequency of the new allele will increase is whether the mutation allows the chickadees better access to food sources than those without it.
What do you mean by Mutation?A Mutation may be defined as sudden, stable, and inheritable changes in the genetic material of an organism.
A mutation changes the whole sequence of the genetic material and causes a change in the genotype as well as phenotypes of an organism.
Therefore, the factor that may determine the frequency of the new allele will increase is whether the mutation allows the chickadees better access to food sources than those without it.

Which physical adaptations increase a plant's chances of survival in a wet environment? (Select 2 correct answers.)
□ having waxy leaves
□ having swollen trunks
□ having deep roots to survive fires
□ having roots that grow above ground
Answer:
I think 1 = having waxy leaves and 4 = having roots that grow above ground
Explanation:
Not Sure how to explain.
In an ecosystem, the physical adaptation which increases a plant's chances of survival in a wet environment is having waxy leaves as it will not allow water to accumulate on the leaves.
What is an ecosystem?Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.
Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.

On a hike through the forest, you notice a population of 100 flowering plants that all look identical. They span an area of approximately 100 square meters, but there are other populations of this species nearby. You take some representatives from one corner of their distribution back to the lab, sequence their DNA and conclude that they are genetic clones. True or false
Answer:
True
Explanation:
They are identical genetic clones so there is no difference which is the key to natural selection, hence given statement is false.
What is natural selection?Since they are genetic clones and hence identical, they lack the phenotypic variation that is essential for evolution to take place through natural selection.
Genetic drift cannot happen since they have the same phenotype and are genetically similar.
Genetic variation must occur randomly for genetic drift to take place there must be a shift in the frequency of one allele over time within a population for genetic drift to take place.
Therefore due to an identical clone, there is no chance of natural selection, hence given statement is false.

State 4 economic importance of meat
Answer:
The meat industry may also be an important component of the export sector, generating not only valuable foreign exchange but also savings through import substitution. Meat production therefore provides the opportunity for converting non-exportable resources into an important component of the national economy.Meat production is an important part of the world economy with important contributions to local, national, and international trade. There may be multiple paths to the future of meat production.The American Meat Institute released a new economic impact study in June that shows the nation's meat and poultry industry contributes roughly $832 billion, nearly 6% of total gross domestic product, to the U.S. economy, along with nearly 6.2 million jobs and $200 billion in wages and benefits.Answer:
The most frequently asked question in a broiler operation is which breed should be used? Integrators tried multiple breeds in their operation and now they have the results . Unfortunately these results most of the time only consist of average daily gain, feed conversion ratios, and mortality. They less often go into any detail about the different yield values they have got in the testing process or even what their product mix consists of. These things are just as important if not more economically than the live factors that go into choosing a breed for an operation.
Of course there are some countries with very large live bird markets and a few countries where the industry is not vertically integrated, and in those situations the meat yield difference of one breed versus another may not be very important. In most poultry markets around the world, however, the end product is meat and the economic factor driving the company is profit per pound or kilogram! Here, a good combination of live performance and meat yield are critical in analysing the most profitable breed for each specific company based on their needs for their product mix.
6. Nuclear power plants produce no
but they do generate
Answer:
Nuclear power plants produce no carbon dioxide emissions, but they do generate greenhouse gasses.
:)
Nuclear power plants produce no greenhouse gases, such as carbon dioxide and methane, which are responsible for global warming and climate change. However, they do generate nuclear waste.
What are nuclear power plants?Nuclear power plants generate electricity by using the heat produced by nuclear fission reactions to boil water and produce steam. This steam then drives turbines, which generate electricity. While nuclear power plants do not produce greenhouse gases or other air pollutants, they do generate nuclear waste, which is radioactive and requires special handling and storage to prevent harm to human health and the environment. Nuclear accidents, while rare, can also have catastrophic consequences, as demonstrated by the Chernobyl disasters.
Hence, nuclear power plants produce no greenhouse gases, such as carbon dioxide and methane, which are responsible for global warming and climate change. However, they do generate nuclear waste.
