Crops are protected from disease-causing fungi by use of fungicides or by the use of genetically engineered fungi-resistant crops. Which statement BEST describes how the two techniques differ in reducing fungal infestations of crop plants?

A) Fungicides kill plants infected with fungi, while genetic engineering modifies fungal DNA.
B) Fungicides kill the source of food for fungi, while genetic engineering helps to make fungi-infected plants edible.
C) Fungicides interfere with fungal growth and reproduction, while genetic engineering produces plants resistant to fungi.
D) Fungicides change fungal DNA, while genetic engineering helps the crops and the fungi to form a symbiotic relationship.

Answers

Answer 1
The answer on USA TestPrep is C.
Answer 2

Correct answer: C). Fungicides interfere with fungal growth and reproduction, while genetic engineering produces plants resistant to fungi.  

Fungicide is a chemical substance that is known to cause toxicity in fungi in order to kill them. Its use can help to reduce the number of fungal infection that causes great loss to plants and its productivity.

In genetic engineering, the DNA of plants is altered in such a way that it produces a toxic protein, which will kill the fungi when it tries to infect them or slow down the growth of the plant.

Identify two ways in which animals can reduce the intensity of intraspecific competition

Answers

Intraspecific competition involves an interaction where by members of the same species compete for limited supply of resources. The end result is the reduction in fitness for both individuals. Animals can reduce the intensity of intraspecific competition by exploiting different type of food resources and also moving to other areas that are sparsely populated and with high amounts of food. 

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.

A black swan and a white swan breed and produce offspring that are gray in color. What is the most likely explanation for this happening?

Answers

Final answer:

Gray offspring resulting from the breeding of a black swan and a white swan is an example of incomplete dominance, where the phenotype is a blend of both parents' traits.

Explanation:

When a black swan and a white swan breed to produce offspring that are gray in color, the most likely explanation for this phenomenon is incomplete dominance. This is a form of inheritance where the phenotype of the heterozygote (gray offspring) is an intermediate phenotype between the two homozygous phenotypes (black and white swans).

To further illustrate this point, if we consider a case where chickens are bred and the first generation results in black chickens with white speckles, when these speckled chickens are interbred, their offspring may show a variety of patterns. According to Mendelian genetics, this could follow a codominance pattern, where both alleles are expressed equally in the phenotype, or continue the pattern of incomplete dominance. Each chicken could have the potential to be speckled, black, or white, depending on the combination of alleles inherited from the speckled parents.

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

Answers

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.

The renin-angiotensin system activates to restore fluid to a normal level when a person is dehydrated.

Answers

The statement is true.
Renin-angiotensin system will be activated when there is a loss of blood volume (or decrease of blood pressure, such as in haemorrhage or dehydration. Renin is secreted by kidneys directly into the circulation when the blood flow is reduced. Renin then stimulates conversion of angiotensinogen, released by the liver, to angiotensin I which will then be converted to angiotensin II by the angiotensin-converting enzyme (ACE) found in the lungs. Angiotensin II is a vasoconstrictor(increases the blood pressure) and also stimulates the secretion of the aldosterone from the adrenal cortex. Aldosterone increases the reabsorption of sodium and water into the blood and the excretion of potassium (to maintain electrolyte balance). This also increases blood pressure and retention of water.

When can antlions experience competition

Answers

Answer:

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.

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?

Answers

lkhffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff

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.

What did rosenberg and trevathan discover in their study comparing human and nonhuman primate birth?

Answers

When comparing the birth patterns of humans and non-human primate, Rosenberg and Trevathan discovered some very clear differences:

1. The human period of labour and child birth is exceptionally long and painful compared to other non-human primates.
E.g. a human labour can last anywhere from 10-20 hours while that of a chimpanzee lasts only 2 hours.

2. Humans have the ability to walk straight, the trade off however is that it is extremely difficult and painful to give birth to a big brained human baby.

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.

Describe pulmonary circulation pathway using the following terms: deoxygenated blood, left atrium, lungs, oxygenated blood, pulmonary arteries, pulmonary trunk, pulmonary veins, and right ventricle

Answers

Definition:
                  "The type of circulation pathway in which venous blood is passed
                   from the right atrium of the heart through the right ventricle  and 
                   pulmonary arteries to the lungs where it is oxygenated and its                             return via the pulmonary veins to enter the left auricle and                                                      participate in the systemic circulation".

Explanation:
                     There are two circulatory path in cardiovascular system namely pulmonary circulation and systemic circulation. Pulmonary circulation path allows for blood circulation through lungs for oxygenation while systemic circulation allows for transport of oxygenated blood to all parts of the body.

Pulmonary Circulation Pathway:
                                                      Pulmonary circulation pathway consist of:

1. Superior and inferior vena cava:
                                                       De-oxygenated blood from lower parts of the body enter to right atrium through inferior vena cava. Similary, deoxygenated blood from upper parts of the body enter to right atrium through superior vena cava.

2. Right atrium and right ventricle:
                                                          From right atrium the blood passes to right ventricle through tricuspid valve. 

 3. Pulmonary artery:
                                Afterwards, the blood enters the pulmonary artery via the pulmonary valve. The pulmonary artery divides into two arteries with one artery entering the right lung and the other artery entering the left lung. When the blood reaches the lungs through the left and right pulmonary arteries, it moves over alveoli via the capillary beds. 

4. Left atrium and left ventricle:
                                                 After the blood gets oxygenated, it moves back to the heart and this time moves into the left atrium, completing the pulmonary circulation path.
