In certain prairie community, a dominant prairie grass species has recently been infected with a virus that disrupts one of the electron transport proteins in the chloroplasts of infected cells. DESCRIBE and EXPLAIN the most likely effects on individual infected plants. *

Answers

Answer 1

Explanation:

The electron transport chain represents the directional flow of electron through electron carriers in the chloroplast and mitochondria in the cell.

The electron transport chain in the chloroplast is involved in the production of the ATP and NADPH. These molecules are synthesized during the light-dependent phase of the photosynthesis process.

If the prairie grass is affected with a virus that interferes with the electron transport chain occurring in chloroplast then the ATP and NADPH will nor be synthesized as a result of which the Calvin cycle will not proceed which require these intermediate to produce glucose. The plant will die ultimately die because of this virus.

Fred and Joe, two unrelated, mature male gorillas, encounter one another. Fred is courting a female. Fred grunts as Joe comes near. As Joe continues to advance, Fred begins drumming (pounding his chest) and bares his teeth. Joe then rolls on the ground on his back, gets up, and quickly leaves. This behavioral pattern is repeated several times during the mating season. Choose the most specific behavior described by this example:_____
a. fixed action pattern
b. learned behavior
c. territorial behavior
d. agonistic behavior
e. social behavior

Answers

Answer is Option "d"

Explanation:

Animals have confrontations just like humans do. And while they certainly don't fight over who gets the last bagel at the coffee shop, they do have conflict over food resources, partners, and territorial spaceThese conflicts are often settled through agonistic behaviour, which comes from the Greek 'agon' for 'struggle.' This type of behaviour includes threatening displays and ritualistic fighting between the individuals involved in the confrontationAgonistic behaviour often looks violent but is rarely so. This is because if a true fight were to break out between the individuals, both would run a high risk of getting hurt. Therefore, it's safer for both parties to 'fight' in an exaggerated, ritualized wayIf they are involved in a conflict over a mate, a bite would quickly end the conflict for one of them. But if both snakes decide to chomp down, then everyone loses because both snakes will dieHence, the right answer is option d "Agonistic behaviour"

Some birds are known as honey guides because they may be followed by humans to wild beehives. When the humans take honey from the hives, the birds are able to feast on the honey and bees, too. This type of relationship can best be described as ____. Question 1 options: parasitism commensalism mutualism symbiosis

Answers

Answer:mutualism

Explanation:

In a mutualistic relation,both organisms involved benefit from the activities of each other. The benefits may be nourishment,shelter, protection etc.

In the above example,the birds are known to guide humans by responding to specific calls made by the human. They guide humans to beehives and then in return gets to feed on left over honey. Both the bird and human benefits by getting nourishment.

Mutualism is unlike parasitism where one of the organism involved benefits and the other organisms Is most likely harmed. It is also not commensalism, where one organism benefits and the other neither benefits nor is harmed

One of Loraine's friends, Marie, started purchasing raw, unpasteurized milk for her children. Marie insists that pasteurization reduces the nutritional quality of milk and raw milk contains phytochemicals that are destroyed during pasteurization. What should Loraine tell her friend about pasteurization?

Answers

The given question is incomplete, the complete question is:

One of Loraine's friends, Marie, started purchasing raw, unpasteurized milk for her children. Marie insists that pasteurization reduces the nutritional quality of milk and raw milk contains phytochemicals that are destroyed during pasteurization. What should Loraine tell her friend about pasteurization?

A: The pasteurization process heats foods to kill pathogenic microorganisms and reduce the total number of bacteria.

B: The pasteurization process denatures protein and kills harmful prions.

C: The pasteurization process evenly distributes fat particles throughout the milk so the cream doesn't rise to the top of the milk.

D: The pasteurization process releases bound calcium and increases absorbable dietary calcium in cow's milk.

Answer:

The correct answer is option A, that is, by the process of pasteurization food is heated in order to eliminate the pathogenic microbes, which eventually diminishes the bacterial number.

Explanation:

The process by which some of the components of food like dairy products and juice are heated slightly so that the harmful bacteria and pathogens get eliminated from the food is known as pasteurization. It is important to kill such bacteria and pathogens as it may cause certain diseases after consumption.  

Pasteurization is the process of treating non-packaged and packaged foods with a mild heat, which is generally less than 100 degree C. The process helps in extending the shelf-life of the food product by eliminating the harmful bacteria and pathogens from it.  

Final answer:

Pasteurization is a process used to kill heat-sensitive pathogens in milk and other food products while maintaining their quality. It does not significantly impact the nutritional quality of milk. The claim that raw milk contains phytochemicals that are destroyed during pasteurization is not accurate.

Explanation:

Pasteurization is a process used to kill heat-sensitive pathogens in milk and other food products while maintaining their quality. It involves heating the milk at a high temperature for a specific time period to reduce the number of disease-causing microorganisms. However, pasteurization does not completely eliminate all microorganisms, therefore, it is still important to handle and store pasteurized milk properly to prevent any potential contamination. The claim that raw milk contains phytochemicals that are destroyed during pasteurization is not accurate, as pasteurization primarily affects microorganisms and does not significantly impact the nutritional quality of the milk.

Sarah is fighting a sinus infection. Her doctor prescribed a nasal spray and an antibiotic to ght the infection. The active ingredients, in milligrams, remaining in the bloodstream from the nasal spray, n(t), and the antibiotic, a(t), are modeled in the functions below, where t is the time in hours since the medications were taken.

Answers

Answer:

The antibiotics has greater initial amount of active ingredient.

Explanation:

Okay, from the question we are given the equation for the medication formula for the Nasal spray and the antibiotics, they are given as equation (1) and (2) respectively;

n(t) = [ (t + 1) / (t + 5) ] + [18 / (t² + 8t + 15) ]. -----------------------------------------(1).

a(t) = 9 / (t+3) ----------------------------(2).

Immediately Sarah used the drug, let us say time,t = 0 is the time in which active ingredients(in milligrams) are much more concentrated in the bloodstream of Sarah.

Therefore at t =0, we are going to have;

n(0) = [ (0 + 1) / (0+ 5) ] + [18 / (0 + 8(0) + 15) ].

n(0) = (1/5 + 18/15).

n(0) = 1.4.

Also, for the antibiotics, the concentration at time,t = 0 is;

a(t) = 9 / (t+3).

a(0) = 9/ 0 + 3 = 9/3 = 3.

a(0) = 3.

The values of the Nasal spay is lesser than that of the value of the antibiotics, therefore we can come to conclusion that "The antibiotics has greater initial amount of active ingredient''.

E. coli can synthesize the amino acid threonine or absorb it from the environment. In the thr operon, the repressor is active when it is bound to threonine. If an E. coli bacterium is in an environment where threonine is absent, will transcription of threonine synthesis genes take place? Why or why not?

Answers

Answer:

Yes, the synthesis of threonine occurs because threonine will not be bound to the repressor, so in unbound state, the repressor will be inactive.

Explanation:

1. If an E. coli bacterium is grown, in an environment where threonine is absent, transcription of threonine synthesis genes take place, because threonine will not be bound to the repressor, so the repressor will be inactive.

2. When the repressor is bound to the threonine, it becomes active, and in the absence of threonine , repressor become inactive because there is no threonine to bind with repressor.

3. So, in the absence of threonine , there is synthesis of threonine occurs.

Final answer:

In an environment where threonine is absent, transcription of threonine synthesis genes will take place in E. coli.

Explanation:

In the third operon, the repressor is active when it is bound to threonine. If an E. coli bacterium is in an environment where threonine is absent, transcription of threonine synthesis genes will take place.

The repressor protein in the third operon actively binds to the operator to keep the genes turned off. When threonine is absent, the repressor does not bind to the operator, allowing transcription to occur. This results in the synthesis of the amino acid threonine.

Overall, the transcription of threonine synthesis genes in E. coli is dependent on the presence or absence of threonine in the environment. If threonine is absent, the genes will be transcribed and threonine will be synthesized.

Students often get the impression that DNA must be replicated prior to protein synthesis. Explain why DNA is only replicated prior to the start of meiosis and mitosis

Answers

Answer:

Because each daughter cell must contain an equal and correct amount of genetic material (DNA)

Explanation:

Mitosis and Meiosis are both types of divisions that cells undergo. They both involve the production of new daughter cells. Each cell contains the information needed by it for its life processes. This information is stored in the genetic material known as DNA.

However, when a cell divides during mitosis and meiosis, two and four new daughter cells results respectively. These daughter cells need to contain the genetic material (DNA) that stores the genetic information needed for their survival. The cell ensures that each daughter cell that will result from the process of mitosis and meiosis contains this genetic material by undergoing a process called DNA REPLICATION before the start of the divisions (mitosis and meiosis).

DNA replication is the process of doubling or duplicating the information in the DNA. Hence, at the end of the replication process, the cell contains two copies of the genetic material (DNA) which separates into the daughter cells equally during cell division (mitosis and meiosis).

Protein synthesis does not need DNA replication as it involves using the information in the genetic material (DNA) to synthesize useful products (protein).

Assume that a mass of magma is constant. What effect will an increase in volume have on the density of the magma?

Answers

Answer:Magmatic density and viscosity exert fundamental controls on the eruptibility of magmas. In this study, we investigate the extent to which magmatic physical properties control the eruptibility of magmas from Iceland's Northern Volcanic Zone (NVZ). By studying subaerial flows of known age and volume, we are able to directly relate erupted volumes to magmatic physical properties, a task that has been near-impossible when dealing with submarine samples dredged from mid-ocean ridges. We find a strong correlation between magmatic density and observed erupted volumes on the NVZ. Over 85% of the total volume of erupted material lies close to a density and viscosity minimum that corresponds to the composition of basalts at the arrival of plagioclase on the liquidus. These magmas are buoyant with respect to the Icelandic upper crust. However, a number of small-volume eruptions with densities greater than typical Icelandic upper crust are also found in Iceland's neovolcanic zones. We use a simple numerical model to demonstrate that the eruption of magmas with higher densities and viscosities is facilitated by the generation of overpressure in magma chambers in the lower crust and uppermost mantle. This conclusion is in agreement with petrological constraints on the depths of crystallization under Iceland.

Explanation:

Final answer:

Increasing the volume of a mass of magma while keeping mass constant will result in a decrease in density, which is analogous to the laws governing the behavior of gases.

Explanation:

When the volume of a mass of magma increases while the mass remains constant, the density of the magma will decrease. This is because density is defined as mass per unit volume, which can be represented by the formula density = mass/volume. If the volume increases and the mass remains the same, there is more space for the same amount of mass, which results in a lower density. This concept is analogous to the behavior of gases, where increasing the volume at constant mass would similarly result in a decrease in density.

For gases, the relationships between pressure, volume, and temperature are described by the gas laws. According to Boyle’s Law, if the pressure of a gas is increased while keeping temperature constant, its volume decreases. Charles' Law states that if the volume of a gas is increased at constant pressure, the temperature also increases. According to Gay-Lussac's Law, if the volume of a gas is increased while maintaining constant temperature, the pressure decreases. Lastly, if the volume increases by adding more moles of gas at constant temperature and pressure, the volume increases in proportion to the amount of gas added.

In the human retina: a) cone cells can detect color, but rod cells cannot. b) cone cells are more sensitive than rod cells to light.c) rod cells are most highly concentrated in the center of the retina. d) cone cells, but not rod cells, have a visual pigment.

Answers

Answer:

option A

Explanation:

Cones provide colour vision while rods cells do not produce colour vision. Rods provide the vision in the dull light (darkness or night), whereas cones are known to give the vision during the day or bright light; Rod cells are more sensitive to light than cone cells and both do have visual pigments with the rod cells possessing rhodopsin and the cone cells having photo-opsins.

Final answer:

Rods and cones are two types of photoreceptors in the human retina. Rods, mainly concentrated at the periphery of the retina, are more sensitive to light and only detect shades of gray, while cones, concentrated at the center, detect colors thanks to three types of opsins. Both have visual pigments which react to light, enabling vision.

Explanation:

In the human retina, there are two types of photoreceptors: rods and cones. Rods are more sensitive than cones to light and are primarily responsible for vision in low-light conditions as well as peripheral vision. On the other hand, cone cells can detect color, differentiate between different wavelengths of light, and provide high-resolution vision. Rod cells do not detect color and only allow for the perception of shades of gray.

Rod cells are most highly concentrated around the peripheral areas of the retina, while cone cells are located near the center of the retina, in a region known as the fovea, where they are most concentrated. This central part of the retina is responsible for our central, high-resolution, color vision.

Lastly, both rod and cone cells contain visual pigments that undergo chemical changes when light falls on them. Rods contain a photosensitive pigment called rhodopsin, while cone cells contain three types of photosensitive pigments or opsins, each sensitive to different wavelengths of light - red, green, and blue. The presence of these opsins is what allows cones to detect color.

Approximately how long has the victim been dead if his body temperature was 60.0°F?

Answers

Answer:

around 8 or 9 or 10 hours.

Explanation:

Answer:

14 or 15 hours

Explanation:

The equation for approximating temperature after death is

37.5°C - 1.5°C * hours = temperature

37.5 is the standard body temperature in degrees Celsius.

60°F = 15.56°C

Plug this Celsius value into our equation.

37.5° - 1.5°(hours) = 15.56°C

Let's solve for hours.

-1.5*hours = 15.56 - 37.5°C

-1.5*hours = -21.94°C

1.5*hours = 21.94°C

hours = 21.94°C / 1.5

hours = 14.62 == 14 or 15 hours.

In the human brain, a great deal of synaptic pruning occurs in early childhood. This pruning appears to be:_______.
A. The unfortunate result of insufficiently stimulating home and school environments.
B. The result of the fact that the cortex is slowly taking over responsibility for functions that have previously been controlled by other parts of the brain.
C. Due to an imbalance of important nutrients, and especially to low levels of the B vitamins in many children's diets.
D. An adaptive process that allows children to deal more efficiently with their environment.

Answers

Answer: D. An adaptive process that allows children to deal more efficiently with their environment.

Explanation:

Synaptic pruning is a natural process between early childhood and adulthood which occurs in the brain. The brain removes the extra synapses during synaptic pruning. Synapses are brain structures that allow the neurons to transmit to another neuron an electrical or chemical signal.  

Synaptic pruning is thought to help the brain transition from adolescence, when it can quickly learn and make new connections, to adulthood, when it is much more stable in its structure, but can concentrate on a single question for longer and conduct more complex thinking processes. Synaptic pruning make brain more adaptive to the external environment in early ages.

Hence, the correct option is D. An adaptive process that allows children to deal more efficiently with their environment.

Final answer:

Synaptic pruning in early childhood is an adaptive process that optimizes brain efficiency by reducing unused synapses and strengthening necessary ones, in line with brain plasticity. Option D is the correct answer.

Explanation:

In early childhood, a great deal of synaptic pruning occurs in the human brain, which is an adaptive process that makes the brain more efficient. This pruning results in the loss of synapses that are unused, while strengthening the ones that are frequently used. Such synaptic pruning enables children to deal more efficiently with their environment and allows for the mastery of more complex skills. Consequently, the correct answer to the question is Option D - An adaptive process that allows children to deal more efficiently with their environment.

Neuroplasticity is critical during early childhood as it underlies learning and memory. Through both the blooming and pruning of neural connections during early development, the brain undergoes significant changes that are necessary for cognitive and functional growth. Therefore, synaptic pruning is not due to insufficiently stimulating environments, nutrient imbalances, or the cortex taking over other brain functions, but is instead a key developmental mechanism rooted in brain plasticity and the optimization of neural circuits.
