An ornithologist has observed two species of nuthatch that appear to live in similar environments: both species forage for insects on the same trees, but one species forages in the upper canopy, and the other species forages in the lower canopy. This is probably an example of A. territorial competition leading to competitive exclusion. B. territorial competition leading to niche overlap. C. Both A and C are correct. D. intraspecific competition that leads to habitat separation. E. coexistence through resource partitioning.
Answers
Answer:
E. coexistence through resource partitioning.
Explanation:
An ecosystem can be defined as the natural living habitats of both living and non-living organisms, in which they interact with one another. Essential services such as plant pollination, water purification, nutrient cycling etc that are being provided by the ecosystem are really very vital, important and useful for the sustenance of life, both for humans and enhances social welfare.
An experiment can be defined as an investigation which typically involves the process of manipulating an independent variable (the cause) in order to be able to determine or measure the dependent variable (the effect).
This ultimately implies that, an experiment can be used by scientists to show or demonstrate how a condition causes or gives rise to another i.e cause and effect, influence, behavior, etc in a sample.
In this scenario, an ornithologist (scientist that scientifically study birds) observed two species of nuthatch, in which both species forage for insects on the same trees; one of the species forages in the upper canopy while the other forages in the lower canopy. Thus, this is probably an example of coexistence through resource partitioning.
Resource partitioning refers to the situation in which different species coexisting in the same environment are able to use available resources differently without interspecific competition among them. Thus, these specifies are able to coexist while staying out of each other's path; no disturbance by one species to the other.

If grasshoppers were removed from this food web, which organism would suffer the most, the bird or the baboon?
Answers
Answer:
If the grasshoppers are removed from this ecosystem the bird will suffer the most.
Explanation:
On the presented food web we can see a food web that is complex and typical for the African savanna. As in all food webs, one organism is important for the survival of another organism or for the survival of numerous organisms. In this case, we have the grasshopper and its importance in the ecosystem, and which animal will be the most affected if it suddenly was not in this ecosystem anymore.
The bird and the baboon both feed on grasshoppers, but there is one big difference, and that is that the grasshoppers are the primary food source of the bird, while the baboon has other food sources as well. This means that with the grasshoppers being out of this ecosystem, the bird will have a very hard time surviving, and if it doesn't adapt quickly enough to feed on something else it will probably go extinct. The baboon, on the other hand, will be affected but not so dramatically as it will continue feeding on the other food sources, though it might suffer some smaller losses in its population.
If the grasshoppers are removed from this ecosystem the bird will suffer the most.
Why bird will suffer the most?The bird and the baboon both feed on grasshoppers, but there is one major difference, and that is that the grasshoppers are the primary food source of the bird, while the baboon has other food sources as well.
This signifies that with the grasshoppers being out of this ecosystem, the bird will have a very hard time surviving and if it doesn't adjust quickly enough to feed on something else it will probably go extinct.
Thus, birds will suffer the most.

How many amino acids must be obtained in the diet because they cannot be made by the body?
Оооо
10
20
Answers
Answer:
10
Explanation:
The body is unable to produce essential amino acids. Because the body is unable to produce 9 amino acids, they must be received through diet. Thus, option A is the best choice.
What are Essential amino acids?An obligatory amino acid, also known as an essential amino acid, is one that the body cannot produce quickly enough to meet need and must thus be obtained from the food.
Humans and other animals cannot generate essential amino acids from metabolic intermediates. The body lacks the metabolic processes necessary to produce these amino acids, thus they must be obtained from an external diet.
The body is unable to produce essential amino acids. They must therefore originate from food. Histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine are the nine essential amino acids.
Therefore, option A is the best choice.

3. With regard to environmental management of waste
rock dumps, what is AMD, how is
it formed and how will you manage dump construction to minimize its
impact on the
environment? [6%]
Answers
AMD stands for Acid Mine Drainage. It is formed when sulfide minerals in rocks are exposed to air and water, resulting in the generation of sulfuric acid and dissolved metals. This acidic and metal-rich drainage can have detrimental effects on the environment, including water pollution and damage to aquatic ecosystems.
To manage dump construction and minimize the impact of AMD on the environment, several measures can be implemented:
Prevention: One of the primary approaches is to prevent or minimize the formation of AMD in the first place. This can be achieved by implementing proper waste management practices, including selecting suitable waste rock materials, limiting the exposure of sulfide minerals to air and water, and employing effective cover systems.
Neutralization: Implementing neutralization techniques can help mitigate the acidity of AMD. This involves treating the drainage with alkaline substances, such as lime or limestone, to raise the pH and reduce its harmful effects on the environment.
Containment: Constructing and maintaining effective containment systems is crucial to prevent AMD from infiltrating surrounding soils and water bodies. This can include using impermeable liners, such as clay or synthetic materials, to prevent the leaching of acidic drainage.
Water management: Proper water management is essential to control the movement and accumulation of AMD. This may involve implementing diversion channels, collection systems, and treatment facilities to contain and treat the acidic drainage before it enters the environment.
Monitoring and maintenance: Regular monitoring of water quality, pH levels, and metal concentrations is necessary to detect any potential AMD issues and take appropriate corrective measures. Ongoing maintenance and management of dump sites are crucial to ensure the effectiveness of preventive and mitigation measures.
AMD, or Acid Mine Drainage, refers to the acidic and metal-rich drainage that is formed when sulfide minerals, typically found in rocks associated with mining activities, come into contact with air and water. The exposure of sulfide minerals to oxygen and moisture leads to chemical reactions, resulting in the generation of sulfuric acid. This acid then dissolves metals present in the rocks, such as iron, zinc, and copper, which further contributes to the contamination of water bodies and soil.
The management of waste rock dumps is essential to minimize the impact of AMD on the environment. Dump construction should incorporate measures that aim to prevent the formation of AMD, neutralize its acidity, contain its spread, and manage water flow effectively. These strategies help to minimize the release of acid drainage and metals into the environment, protecting water quality and ecosystems.
The management of waste rock dumps is critical in mitigating the formation and impact of Acid Mine Drainage (AMD). By implementing preventive measures, neutralization techniques, containment systems, effective water management, and regular monitoring, the environmental impact of AMD can be minimized. Adhering to best practices and regulations ensures responsible waste management and helps safeguard water resources and ecosystems.

Which correctly describes the body systems involved in regulating the body's internal temperature when the body is too hot?
A. The circulatory system narrows blood vessels after the brain sends signals through the integumentary system that the body is getting too hot
B. The circulatory system releases sweat after the brain sends signals through the nervous system that the body is getting too hot
C. The integumentary system narrows blood vessels after the brain sends signals through the circulatory system that the body is getting too hot
D. The integumentary system releases sweat after the brain sends signals through the nervous system that the body is getting too hot
Answers
The circulatory system releases sweat after the brain sends signals through the nervous system that the body is getting too hot correctly describes the body systems involved in regulating the body's internal temperature when the body is too hot. So the correct option is B.
When the body temperature rises, the brain sends signals through the nervous system to the sweat glands in the skin to produce sweat. The sweat is then released onto the surface of the skin, where it evaporates, cooling the skin and regulating the body's internal temperature. The circulatory system also plays a role by dilating blood vessels in the skin, which increases blood flow and heat loss through radiation and convection. This process helps to dissipate heat and keep the body's temperature within a normal range.
Overall, the body has a complex system to regulate internal temperature to maintain homeostasis. By understanding how the body works to maintain temperature, we can take steps to prevent heat-related illnesses, such as staying hydrated, avoiding overexposure to the sun, and wearing light-colored and loose-fitting clothing during hot weather.

Body Surface Area -adapted from the Redlarski’s paper (link)
Body surface area (BSA) plays a key role in several medical fields, including cancer chemother-
apy, transplantology, burn treatment and toxicology. BSA is often a major factor in the
determination of the course of treatment and drug dosage. A series of formulae to simplify
the process have been developed. Because easy-to-identify, yet general, body coefficient re-
sults of those formulae vary considerably, the question arises as to whether the choice of a
particular formula is valid and safe for patients. These empirical formulae are derived by
observing/fitting the experimental data and do not have a rigid model or reason explain-
ing their validity. In this problem, you will build a physics model to create your own BSA
equation other than using an empircal formula.
(a) Use a cylinder of height H and radius r as a approximation of the shape of a human.
Calculate the human’s body surface area(BSA), volume(V), and mass(M) in terms of
r and H. You may assume the density of human is 1000 kg/m3.
(b) Rewrite the surface area in in terms of height and mass.
(c) According to the equation you derived above, what is your body surface area? Is it the
same as the result calculated by using the empirical fomulae: BSA = √M H/C with
BSA in m2, M in kg, H in cm, and C=60 is a constant in this paper? If not, what is the percentage differences?
Note: percentage difference for two values E1 and E2 are |E1−E2|
(E1+E2)/2 ×100%.
(d) Considering the formula BSA = √MH/C with fixed H, plot a graph with BSA on
the y-axis and M on the x-axis. Explain what the trend/curve means.
(e) Considering the formula BSA = √MH/C with fixed BSA, plot a graph with H on

Answers
a)Using a cylinder of height H and radius r as an approximation of the shape of a human, the surface area, volume, and mass are calculated in terms of r and H as follows:
Surface area (S) of a cylinder is 2πrh + 2πr², where h is the height, and r is the radius of the cylinder. In this case, the height of the cylinder is equivalent to the height of the human body. Hence;S = 2πrH + 2πr²Mass (M) of a cylinder is given by M = ρV, where ρ is the density of the cylinder, and V is the volume. Hence, the mass of a cylinder in terms of its radius and height isM = πr²HρVolume (V) of a cylinder is given by V = πr²H. Hence, the volume of a cylinder in terms of its radius and height isV = πr²H(b)The body surface area (BSA) of a human can be rewritten in terms of the height (H) and mass (M) as follows:
BSA = √(M/H C)We can rewrite it as H = M/ (BSA² C)Thus, H can be expressed as a function of M and BSA asH = M/(BSA² C)(c)If r = 0.15 m and H = 1.70 m, then using the equation, S = 2πrH + 2πr², the body surface area is given as:
S = 2π (0.15)(1.70) + 2π (0.15)² = 1.77 m²Using the empirical formula, BSA = √(MH/C) with M = 60 kg and H = 170 cm, we get BSA = 1.85 m²The percentage difference is given by;|E1 − E2| / (E1 + E2) / 2 × 100%where E1 = 1.77 m² and E2 = 1.85 m²Thus;|1.77 – 1.85| / (1.77 + 1.85) / 2 × 100% = 4.2%(d)Considering the formula BSA = √(MH/C) with fixed H, a graph with BSA on the y-axis and M on the x-axis can be plotted.The trend shows a non-linear increase in BSA as the mass increases.
(e)Considering the formula BSA = √(MH/C) with fixed BSA, a graph with H on the y-axis and M on the x-axis can be plotted.The trend shows a linear increase in height as the mass increases.

A differential interference contrast microscope uses __________ to examine a specimen. which type of microscope would one use to examine the internal structure of a nucleolus?
Answers
A differential interference contrast microscope uses light to examine a specimen. The microscope used to examine the structure of the nucleolus is a transmission electron microscope.
What is an electron microscope?The electron microscope achieves extraordinarily high resolution by illuminating the object of investigation with an electron beam rather than a light beam. A specimen with a thickness of up to one micrometer can be imaged using a transmission electron microscope (TEM). Compared to TEMs, high-voltage electron microscopes operate at substantially greater voltages.
A picture of the specifics of the surface structure is constructed using the scanning electron microscope (SEM), which scans an electron beam over the surface of a solid object. In contrast to the SEM, the environmental scanning electron microscope (ESEM) is suitable for studying damp objects, including certain live creatures. It can provide a scanned picture of a specimen in an atmosphere.
