https://media.hhmi.org/biointeractive/click/lionfish-invasion/introduction.html This section starts explaining how scientists use the population survey data that are collected to model how the lionfish population changes over time. These models enable scientists to make predictions about population changes, which is an important element of developing plans for managing the lionfish population You'll be using the discrete-time logistic model that is described on this page in future parts of the case study, so make sure to carefully read through the explanation of this mathematical model. Even if you don't have a strong math background, this case study walks through the equation step by step.   6)Which of the following are constant terms in the discrete-time logistic model? choose all that apply a)Nt b)ΔN c)t d)K e)Δt f)rmax,d g)None of these

What are some of the traits present in the newt population described in the article?How might these traits change from individual to individual? (Hint: Do you think the newts are all exactly the same color or size?)

The Tibetans and Han Chinese share several genetic traits and DNA. However the EPAS1 gene which increases the ability of red blood cells carry oxygen even in low environments, is only commonly found in the Tibetan population that live in higher elevations. Explain why this gene is commonly in Tibetan populations from the perspective of competitive advantage and natural selection. Write your answer in 3-5 sentences

A UNF research team was exploring populations of worms on Greenwich and Half Moon Islands. They counted the number of worms on each island and recorded the information below. Greenwich Island AA: 42 Aa: 108 aa: 83 Half Moon Island -AA: 57 Aa: 21 aa: 49 What is the dominant allele frequency for Greenwich Island? Retain 3 decimal places.

A set of beliefs and practives that involves the controlled selective breeding of human populations with the hope of improving their heritable qualities, especially through surgical procedures like sterilization and legal rulling that affect marriage rights for interracial couples, is known as: A) non-concordance B) biological determinism C) eugenics D) natural selection

Please help with the following: Lactase persistence is an adaptation to milk drinking that has developed since the beginning of agriculture ~10 KYA. What is the relationship between the alleles driving this ability in European, Indian and African populations? A. One allele is responsible for lactase persistence in Europeans and Indians because of where agriculture originated and was introduced through migration. routes. B. The allele responsible for lactase persistence in all three populations is the same allele on the LCT gene. C. Different alleles are responsible for lactase persistence in each population. D. One allele is responsible for lactase persistence in Europeans, but other alleles cause the trait in Indian and African populations. E. One allele is responsible for lactase persistence in Africans, but other alleles cause the trait in European and Indian populations.

Match the description with the correct term. the idea that different mating calls of birds used during mating season has led to different species of birds two populations become reproductively isolated (can no longer reproduce successfully) a common ancestor diversifies and the various species all have different adaptations organisms that have a common ancestry but develop body parts that perform different functions  the idea that inherent variation in a population allows for certain traits to be selected for and carried on to future generations of the population experiencing an environmental pressure a model suggesting the gradual change of a species in a linear fashion to form distinct species 1.biological barrier to reproduction 2.theory of natural selection 3. adaptive radiation 4. homologous structures 5. speciation 6. gradualism
