a woman is a healthy carrier of the cystic fibrosis gene (a recessive trait) and her husband is an unaffected male. what is the probability of an unaffected child from this pairing
Answers
The probability of having an unaffected child from the pairing = 0.5
Assumption
Let ; X = Dominant trait
y = recessive trait
The woman been a healthy carrier will have an allele combination of ; Xy
while the unaffected male will have = XX
Their offsprings will have the following allele combinations
X X
X XX XX
y Xy Xy
Number of allele combinations = 4
Number of carrier = 2
Number of unaffected = 2
∴ probability of having an unaffected child = 2/4 = 0.5
Hence we can conclude that The probability of having an unaffected child from the pairing = 0.5

Based on this phylogeny, the archosaurs are a ______. Multiple choice question. monophyletic group polyphyletic group paraphyletic group
Answers
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.

Answer:
66 million years ago
Explanation:
The age of dinosaurs, has been discovered. The tiny fossil, nicknamed the "wonderchicken," includes a complete skull hidden inside pieces of rock, and dates to more than 66 million years ago.
Answer: Now that you know how many half-lives have passed for your fossil, you need to multiply your number of half-lives by how many years are in one half-life. This gives you an age of 2 x 5730 = 11,460 years.

6. Nuclear power plants produce no
but they do generate
Answers
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.

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
Answers
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.
