Why do males express certain sex-linked traits that females don't?
Answer: A male with a mutation in a gene on the X chromosome is typically affected with the condition. Because females have two copies of the X chromosome and males have only one X chromosome, X-linked recessive diseases are more common among males than females.

B)codominance
C)simple dominant recessive pattern
D)getting bit by a cobra
Answer: A
Explanation:
Answer:
b
Explanation:
you can already get rid of d and c because you know that it has something to do with combining the 2 alleles. Incomplete dominance is when the 2 colors blend together to make another color, like a red and white flowers offspring is pink. codominance is when both alleles are shown, just like the black spots on the chicken. your answer is b!!

As the level of Carbon Dioxide in the atmosphere increases, how will (is) primary productivity impacted? How does this impact populations of primary consumers?
Answer:
Rising atmospheric carbon dioxide (CO2) and nitrogen (N) deposition increase directly the resource availability to plants, and can increase plant growth and net primary productivity (NPP; Norby et al., 2005).
Net primary productivity varies among ecosystems and depends on many factors. These include solar energy input, temperature and moisture levels, carbon dioxide levels, nutrient availability, and community interactions (e.g., grazing by herbivores) 2.
Explanation:
Primary producers capture light from the sun and carbon dioxide from the environment and finally transform it into energy.
What do you mean by Net primary productivity (NPP)?Net primary productivity may be defined as the amount of matter accumulated by plants per unit area in a given time.
Primary productivity depends on photosynthesis, where carbon dioxide gets converted to energy. If the level of Carbon Dioxide in the atmosphere increases, the photosynthesis rate increases, and finally the primary productivity increases.
Therefore, Primary producers capture light from the sun and carbon dioxide from the environment and finally transform it into energy.

Hard corals have a symbiotic relationship with species of microalgae that give the corals their color and provide up to 95% of the corals' energy needs by photosynthesis. Corals get the rest of their food by consuming plankton. The microalgae are damaged by changes in water temperature 2-3C lasting five weeks or more, causing a phenomenon called coral bleaching. What will most likely be the result of increased global temperature on the diversity of hard coral species?
Question 1 options:
The hard corals will make all of their own food.
The rate of photosynthesis in hard corals will increase.
The number of different hard coral species will decrease.
The hard corals will migrate to warmer waters.
Answer:
The hard corals will make all of their own food
Explanation:
your welcome...
The most likely result with increased global temperature would be ; ( A )
The hard corals will make their own food
Given that the relationship between the corals and the microalgae is symbiotic and not parasitic therefore when the microalgae are damaged the hard corals will most likely look for an alternative food source in order to continue surviving since they do not rely 100% on the plankton for their food. which is The hard corals will be able to make their own food by capturing preys like critters.
Hence we can conclude that the most likely result with increased global temperature would be The hard corals will make their own food

Explain how privatizing endangered species (private ownership) will save them from extinction. Give an example. (approximately 5 sentences) Also, explain why prohibiting trade of endangered species will accelerate their rate of extinction. Be sure to discuss the tragedy of the commons, and the prisoner's dilemma in your answer. (About 8sentences)
Answer: The privatization of endangered species will reduce their chances of extinction.
Explanation:
The endangered species are those species which are low in numbers, their population will reduce or extinct in the near future. The privatization of these animals will protect them from dangers of trafficking, predation, habitat loss, and death due to natural disaster. Animals like elephant, monkey, tiger, lion are privatized to protect their extinction.
The trade of hides, teeth, ivory, flesh, horn, and other parts of the endangered animals will accelerate the rate of extinction. Prohibition of trade will allow the agents of trafficking to get chances of killing and stealing animal parts to a large number.
The tragedy of commons suggests that people neglect the well being of the society for personal gain. Those people who exploit the resources from endangered species causing harm to the nature as they are responsible for reducing biodiversity.
Extinction is defined as the elimination of species due to natural or human-made factors. The species are necessary to preserve the ecosystem and biodiversity.
The private ownership of endangered species (species on the verge of extinction)can save the species from extinction. Private ownership will reduce their chances of being hunted, exported, traded, predation, loss of habitat, and death due to natural calamities.
The animals like elephants, monkeys, crocodiles, snakes, and lions are categorized in private ownership to prevent their extinction.
The ban on the trading of endangered species can or might save the species from extinction, but it can also backfire leading to market booms. The prohibition will allow the traders to follow animal trafficking and stealing, which can result in an increased rate of extinction.
The killing of animals for ivory, fur, skin, teeth, and flesh and selling them in the black market will lead to an increase in their rate of extinction.
The tragedy of commons refers to the negligence of the social surrounding for personal gains. The people who exploit resources and cause harm to endangered species are indirectly harming nature, and therefore responsible for the reduction in biodiversity.

Give them a prescription medication, then continue training session D. Give them Advil, then continue training session
Answer:
A .recommended they drink water then stop training session
Explanation:
Because the trainer can't just give out prescription medication. They don't know if the person has allergies and it can make the clients headache worse.
A. Recommend they drink water, then stop the training session
First thing first, drug abuse is not an option. Drug abuse includes self medication or taking drugs not prescribed by a medical practitioner. As a fitness trainer, ones job is not to prescribe drugs.
According to this question, if a client is experiencing headaches during a training session, the best alternative for the trainer is to recommend taking water to calm the client down, then put an hold to the training. The trainer is not qualified to prescribe any drug whatsoever.
Therefore, the trainer should recommend that a client with headache drink water, then stop the training session.

Allele frequencies for a particular trait are shown over five generations for a population of sexually reproducing organisms.
According to the frequency changes over the generations, which hypotheses can be supported? Select ALL that apply.
Answer:
The answer is A,B and C
Explanation:
The correct options are A, B and D. The frequency of an allele in a population is referred to as its allele frequency.
What is allele frequency?It is calculated by dividing the number of gene copies by the number of times the allele occurs in the population.
Additionally, it is feasible to determine genotype frequencies (the percentage of people who share a particular genotype) and phenotype frequencies (the percentage of people who share a particular phenotype).
Different from genotype or phenotypic frequency is allele frequency. Calculating genotype and phenotypic frequencies is also useful for studying how populations change, although they are not the same as allele frequency.
Therefore, The correct options are A, B and D. The frequency of an allele in a population is referred to as its allele frequency.

According to the endosymbiotic theory, why was it adaptive for the larger (host) cell to keep the engulfed cell alive, rather than digesting it as food select all that apply
Answer:
It provides ATP.
Explanation:
It is adaptive for the larger host cell to keep the engulfed cell alive, instead of digesting it as food because the engulfed cell provides energy in the form of adenosine triphosphate (ATP) to the host cell. The larger host cell is able to survive in anaerobic conditions with the help of engulfed cell alive so that's why we can conclude that the larger host cell keep the engulfed cell alive instead of killing it and used as a food source.
