45 foxes of genotype aa (long ears), 30 foxes of genotype (aa), 25 foxes aa (short ears), what are the allele frequencies in this population?
To calculate allele frequencies for the fox population, it's noted that all foxes have the genotype 'aa' indicating only one allele 'a' is present. Therefore, the frequency of allele 'a' is 1 or 100%, as there are no other alleles indicated.
To calculate the allele frequencies in the fox population with the given genotypes, we need to count the total number of alleles and then the number of each allele. Given the genotypes 'aa' for long ears, 'aa' (repeated, possibly a typo), and 'aa' for short ears, we can assume that there are only two phenotypes (long ears and short ears) associated with a single genotype (aa). This implies that there is only one type of allele present in the population, which is 'a'. Therefore, the frequency of allele 'a' is 1, or 100%, since no other allele type is present.
In cases where multiple alleles are present (e.g., A and a), one would count the number of 'A' and 'a' alleles separately, and then divide by the total number of alleles in the population. This would give the frequency of each allele, ensuring that the sum of frequencies for all alleles equals 1.

Identify two ways in which animals can reduce the intensity of intraspecific competition
Final answer:
Animals can reduce intraspecific competition by changing behaviors to minimize competition and by niche differentiation, where they use different resources or habitats within the same environment.
Explanation:
Two ways in which animals can reduce the intensity of intraspecific competition include behavior changes and niche differentiation. Firstly, animals can change their behaviors to avoid direct competition for resources, such as switching their active hours to avoid competition for food. Secondly, they can engage in niche differentiation where individuals of the same species exploit different habitats or resources, reducing direct competition. An example of this in interspecific competition is observed in anolis lizards, where specialization in their habitat selection, such as being ground-dwellers or tree-dwellers, decreases the overlap in resource use among different species. Similarly, in intraspecific competition, animals of the same species can evolve different adaptations that allow them to use varied resources or live in different habitats, thus reducing direct competition for the same resources.
Breast milk _____. is more likely than formula to produce allergies is deficient in iron and vitamin c provides antibodies to fight diseases upsets the baby's digestive system more than formula
Breast milk provides antibodies to fight diseases.
Breast milk is produced by mammary glands in the breasts and its main function is feeding an infant. Breast milk is the primary source of nutrition for newborns. The composition of the milk includes immune-boosting white blood cells, as well as stem cells, which can help organs develop, antibodies, proteins, amino-acids, oligosaccharides, growth factors, hormones, enzymes, vitamins, minerals…
Final answer:
Breast milk provides antibodies to fight diseases, which are crucial for the infant's developing immune system
Explanation:
Breast milk provides antibodies to fight diseases, which are crucial for the infant's developing immune system. These antibodies are passed to the infant through breast milk in what is known as active immunity. The immunoglobulins in colostrum and breast milk help increase the newborn's immune defenses. Breast milk contains all the necessary nutrients and hydration that a growing infant requires for the first 4–6 months of life and is tailored to suit each stage of the newborn's development.
The composition of breast milk helps the newborn's digestive system to expel meconium and clear bilirubin and is generally less likely to upset the baby's digestive system than formula. Compared to cow's milk, breast milk has more appropriate levels of fat and lactose for an infant's needs and contains proteins that are easier for the infant to digest. Cow's milk contains more protein and minerals, which are difficult for an infant's immature digestive system to metabolize, and therefore, it should not be given to infants.

A serious, inflammatory condition in which the colon mucosa protrudes through the colon wall is called __________.
A serious, inflammatory condition in which the colon mucosa protrudes through the colon wall is called diverticulitis. Diverticulitis is a related digestive condition that affects the colon. This condition occurs when naturally weak part of the colon tears which result in inflammation or infection. Symptoms of diverticulitis include severe abdominal pain, fever, nausea and constipation.

When can antlions experience competition
It happens when there is extreme scarcity of the food items.
Explanation:This would happening to take place as during the course of the larval stage at the time when there is an overlapping set of the reproduction. This is all possible at the time when the large ones are in consumption with the small set of the survivals.
Since antlions larvae are semi-sedentary and develop a sit-and-wait strategy to feed, they experience the strongest competition during this larval stage of their cycle.
----------------------------------------
The species receives its name because of the feeding habits of the larval stage. Larvae are strong predators that feed mainly on ants.
Since antlions larvae are semi-sedentary, their feeding strategy is sitting and waiting.
They dig conical-shaped holes in the substrate and remain hidden in the bottom, where they wait for prey to fall into the pit.
Competition is stronger during the larvae stage because they need to be strategic in positioning the pit.
Pits are usually built near the ant's nest to increase the probability of getting prey. However, the closer the pits are to each other, the fewer chances of getting prey. Pits that first block the ants' way will be the ones that get the prey and not the other ones. This competition is known as shadow-competition.
Larvae compete for the space in which to build their tramps. And dispersion turns a significant factor to avoid competition.
It has been hypothesized that antlion larvae reduce shadow competition and increase the feeding probability by building their pits away from others and closer to the source of prey.

Pamela has started to take antibiotics, which kills most of the helpful and harmful bacteria in her body. Her doctor suggested she eat yogurt containing helpful bacteria to reestablish the bacteria in her digestive tract. Why is this important?
Answer: Yogurt contains good bacteria.
Explanation: Taking antibiotics for a longer duration of time kills the good bacteria present in the the gut of the human being. The gut of the human being consists of good bacteria as well as bad bacteria.
The good bacteria present in the gut of the human beings helps in the digestion of the food. Yogurt is a good source of good bacteria as it contains lactobacillus which is known as good bacteria that keeps the gut healthy.

What did rosenberg and trevathan discover in their study comparing human and nonhuman primate birth?
Answer: Rosenberg and Trevathan discovered birth patterns in primates and non human primates. They compared the birth patterns of human, gorilla, gibbon, monkey to understand the similarity and differences among them.
In case of monkey and gibbon the dimension of the neonatal cranium have very minute difference to that of their mother's pelvis. When we talk about great apes like gorilla and pan the size of pelvis is large as compared to the cranium size of their neonates and the pelvic inlet is spacious. In terms of human being the cranium size of the neonates is longer than the anterior and posterior dimensions of the pelvic inlet which requires the head to pass through the inlet facing transversely.
