Answer:
The biology branch deals with the relations between and physical environment of organisms.
Explanation:
The principle of competitive exclusion states that if two species occupy the same niche, they cannot exist together (competing for identical resources). Two species whose niche overlap can evolve to have different niches through natural selection, resulting in the distribution of resources.
In ecology, interspecific competition is a form of competition where individuals from different kinds compete in an ecosystem for the same resources (e.g. food or space)... There may be interspecific competition if people of two separate species share a limited resource within a single area.

The reason that the mail bed appears pink is the presence of a larger number of melanocytes in the underlying dermis
Complete question:
True or False: The reason that the nail bed appears pink is the presence of a larger number of melanocytes in the underlying dermis.
Answer:
False
Explanation:
Nails are composed of the lamina, which is a smooth, shiny, translucent, and keratinized structure. The nails are born the nail matrix. The newly formed nail slice along the mail bed, which is the plane surface under the nails.
The nail bed places under the nail and is composed of a thin epithelium, with no granulous stratum, and a few layers of parakeratotic cells attached to the nail.
The nail matrix and nail bed have melanocytes. Half of the melanocytes of the matrix produce melanin, while melanocytes of the nail bed are inactive.
The nail bed is laying over many small vessels that nourish it and provides a pink color to the nails.

During the light reactions of photosynthesis, plants convert light energy into energy the plant can use. Where is the energy stored
Answer:
Photosynthesis is a process where plants and other organisms convert energy from the sun into a chemical energy that through cellular respiration can be later released in order to fuel the organism's metabolic activities.
The energy which is stored in the form of sugar is broken down into starch entering the mitochondria to produce energy. The energy is stored in the chemical bonds. To obtain the energy, organisms take energy-rich compounds such as glucose and breaks them down to release their energy. The organism traps the released energy and stores it in a form of adenosine triphosphate or ATP.

Efforts to reduce pollution began occurring later in the century. If pollution near factories was reduced, what would happen to the color of the moths? Explain your answer.
Answer: The color of the moths will become light.
Explanation:
Due to industrial exposure of smoke and dust the white color moths adapted a phenotypic trait of dark brown feather color which used to mimic the color of the tree trunk so the moth population was able to camouflage the predatory birds as these moths remain undetected. But due to reduction in pollution the tree trunk color regain its lighter color and these dark colored moths were detected by the predators so the dark color moth population decline and the white color of feather became the phenotypic trait passed in the next generation enabling the moth population to survive in reduce pollution conditions.
At a chemical synapse, the intensity of the stimulus is coded by _______. At a chemical synapse, the intensity of the stimulus is coded by _______. the amount of calcium that enters the axon terminal the amount of neurotransmitter released and the amount of calcium that enters the axon terminal the amount of neurotransmitter released the size of the action potential the size of the action potential and the amount of neurotransmitter released
Answer:
The correct answer is - the amount of neurotransmitter released and the amount of calcium that enters the axon terminal.
Explanation:
The intensity of the signals or stimulus depends on the amount of the neurotransmitter such as acetylcholine, dopamine and the amount of calcium that enters the axon terminal.
A neurotransmitter is a chemical that carries, boost or balance a signal and send stimulus or signals throughout the body. When an action potential reaches the nerve terminal calcium channels open and enters.

Which sentence best summarizes the two competing models of planet
formation?
O A. The core accretion model states that planets form when clumps
of gas and dust collapse, while the gravitational instability model
states that small bodies grow bigger and attract layers of gas to
form planets.
O B. The gravitational instability model states that planets form when
clumps of gas and dust collapse, while the core accretion model
states that small bodies grow bigger and attract layers of gas to
form planets.
C. The gravitational instability model states that planets form
because changes in the new sun's gravity pull particles together,
while the core accretion model states that gravity between large
bodies pulls them apart into pieces that form planets.
D. The core accretion model states that planets form because
changes in the new sun's gravity pull particles together, while the
gravitational instability model states that gravity between large
bodies pulls them apart into pieces that form planets.
Answer:
A
Explanation:
A. The core accretion model states that planets form when clumps of gas and dust collapse, while the gravitational instability model states that small bodies grow bigger and attract layers of gas to form planets.
What are the models of planet formation?There are two main models of planet formation: the core accretion model and the gravitational instability model.
The core accretion model states that planets form when small particles, such as dust and gas, clump together and gradually grow into larger bodies. These bodies continue to attract more material, eventually forming a planet. This model is supported by the observed existence of small, solid bodies, known as planetesimals, in the early solar system.
The gravitational instability model, on the other hand, proposes that planets form when small bodies within a protoplanetary disk (a disk of gas and dust surrounding a young star) grow larger and become gravitationally unstable. This causes them to collapse and attract layers of gas, eventually forming a planet. This model is supported by the observation of large, gaseous planets, such as Jupiter, in the solar system.

Answer:
Three phenotypes:

Earthquakes release phosphorus.
Phosphorus is carried in the rain that was evaporated from lakes.
Human use of fertilizers release phosphorus into the groundwater.
Phosphorus is transpired from the leaves of plants.
Answer:
I think the correct answer from the choices listed above is option C. A way in which phosphorus may enter into the phosphorus cycle is that when human use of fertilizers release phosphorus into the groundwater. Hope this answers the question. Have a nice day.
Human use of fertilizers releases phosphorus into the groundwater is a way in which phosphorus may enter into the phosphorus cycle. Therefore, the correct statement is option C.
What is the use of phosphorus?Phosphorus is a nutrient needed by plants to grow, and it is added to soil in the form of fertilizers. When it rains, the phosphorus is washed away from the soil and carried into nearby rivers, lakes, and groundwater.
The phosphorus is then taken up by plants or become part of the sediment at the bottom of bodies of water.
Phosphorus can be transformed from there and recycled through the different parts of the phosphorus cycle, such as weathering, erosion, and sedimentation. Phosphorus can also be released from the decomposition of organic matter.
Therefore, human use of fertilizers releases phosphorus into the groundwater is a way in which phosphorus may enter into the phosphorus cycle.

Workout the path taken by a carbon molecule as it moves from being part of the co2 in the air to being part of a starch molecule in a plant
Answer: The conversion of carbon dioxide occurs into glucose via photosynthesis.
Explanation:
The plants absorb carbon dioxide gas from the atmosphere. This is one of the reactants of the photosynthesis process. The water and carbon dioxide are the reactants of the photosynthesis process in the presence of sunlight the molecule of water splits into hydrogen and oxygen gas is liberated as byproduct and carbon dioxide becomes the product of the glucose. The monomers of glucose combine to form starch molecule which is stored as energy reserve in plants.

Answer:
D.They carry human waste to treatment facilities away from cities.
Explanation:
Sewage system is a collection of systems that carries sewage (human waste) from the point it was produced to a place where it'll be treated or recycled.
Since sewage is moved via the use of sewage system, it helps to fight the spread of disease by carrying human waste (sewage) to treatment facilities away from cities.
