Describe how the relative surface temperature and the relative luminosity of Aldebaran would change if it collapses and becomes a white dwarf like Procyon B
Answer:
Greatly affect the luminous intensity.
Explanation:
The relative surface temperature and the relative luminosity of Aldebaran will greatly decreases if it becomes Procyon B because more surface area of a star increases the luminous intensity of that star. The size of Aldebaran is 30.7 million km whereas the size of Procyon B has 8585 km which very much lower than the Aldebaran so there is a great difference in the magnitude of luminosity between Aldebaran and Procyon B. So we can conclude that the decrease in the surface area of a star will greatly affect its luminous intensity.
How might the loss of sea ice affect people, animals, or ecosystems?
Answer:
The Global Impacts of Arctic Sea Ice Loss. Some of the most important climate news this winter has been around the alarming lack of sea ice in the Arctic, which has been in decline due to the steady rise in Earth’s average air and ocean temperatures. While suffering polar bears are a poignant symbol of climate change, the effects of disappearing ice extend far beyond the Arctic circle and its inhabitants.

A. Condensation
B. Infiltration
OUTPUT
C. Sublimation
STATION
D. Evaporation
3.
Answer:
1. D
2. B
3. A
Explanation:
The dashed circle indicates the process of infiltration because the water of precipitation goes inside the soil. Infiltration is the process in which water enters the soil through small opening present on the earth surface. When the clouds are formed, precipitation occurs in the form of rainfall and snowfall. Condensation is a process in which water vapors change into liquid when the environment has low temperature or cool so condensation occurs on the windows of Erica.
Which of the following is a true statement?
A. Disruptions in an ecosystem are normal and natural changes.
B. Disruptions in an ecosystem are caused by both human activity and environmental disturbances.
C. Ecosystems are complex, interactive systems that include both biotic and abiotic components of the environment. D. All of these are true statements.
Answer:
All the statements are true and the correct option is;
D. All of these are true
Explanation:
Ecosystems change over time. ... Sudden disruptions such as volcanoes, floods, or fires can affect which species will thrive in an environment. Other disruptions are caused by human activities
An ecosystem ecosystem is an area where a community living (biotic) and non living (abiotic) things such as plants, animals, other organisms, landscape, natural sources and weather interact to create an apparently sustainable system
An ecosystem undergoes several changes over time due to environmental disturbance which results in the variation of the ecosystem's structure and change rate due to the natural disturbance and/or human activity
Therefore all the statements are true.
how does a chemical equation differ from a mathematical equation?

Which of the following factors would best contribute to a measurement of environmental quality?
Average temperature
Water clarity
Salinity levels
Average speed of sound
Answer:
water clarity
Explanation:
The factor that will best contribute to the measurement of environmental quality is : ( B ) Water clarity
What is water clarity ?Water clarity shows how far light can penetrate a water body. A very clear water in an environment shows that the water bodies contain little or no suspended soil particles.
Very clear water found in a environment represents a very high quality of live in the environment and can be used to measure the environmental quality.
Hence we can conclude that The factor that will best contribute to the measurement of environmental quality is : ( B ) Water clarity

What type of carbon-based molecule is the first to be broken down by the body's cells to provide a source of energy?
Answer: Glucose
Explanation:
The carbon based molecule which is broken by the cells of the body is glucose it is a carbohydrate that is obtained from food we consume it is stored in the form of glycogen. When the energy requirement of the body increases then glucose monomers are released from the glycogen chain so that glucose monomers can participate in the energy generation process in the mitochondria of the cell. The chemical energy so produced is ATP (adenosine triphosphate).

To be a possible answer to a scientific question, a hypothesis must be
testable.
unique.
written.
controlled.
Answer:
A hypothesis is a possible explanation for a set of observations or an answer to a scientific question. A hypothesis must be testable and measurable. This means that researchers must be able to carry out investi- gations and gather evidence that will either support or disprove the hypothesis.
Explanation:
A. Mutualism
B.Commensalism
C.Parasitism
D.Predation
Answer:
D.Predation
Explanation:
Living organism interact with one another in their natural environment. The interaction of two organisms is called SYMBIOSIS. Symbiosis, however, can be of different types depending on how the organisms relate. One type of symbiotic relationship between organisms is called PREDATION.
Predation is a relationship between two organism in which one organism called PREDATOR kills and feeds on the other organism called PREY in order to obtain energy. In this question, a Manta Ray and a zooplankton is shown.
The Manta ray is described as an aquatic organism that feeds on tiny species like fishes while the zooplankton is a tiny organism found in water bodies. The Manta Ray is the predator that kills and feeds on the zooplankton, hence, the relationship is a PREDATION.

Using an example for each, explain the following ecological concepts.
a) Succession
b) Energy flow between trophic levels
c) Limiting factors
Answer:
1-Ecological succession is the process of change in the species structure of an ecological community over time.
2-Energy decreases as it moves up trophic levels because energy is lost as metabolic heat when the organisms from one trophic level are consumed by organisms from the next level.
3-A limiting factor is a variable of a system that causes a noticeable change in output or another measure of a type of system.

When an object is already in motion, why is energy required to stop it
When an object is already in motion then we require force to stop it because due to inertia , a body tends to remain in the state of motion unless an external force acts on it .This is in accordance with Newton's first law of motion or law of inertia of motion.
What is inertia ?Inertia is the tendency of a body to remain the way it is. It opposes any changes to its state of rest or motion.
The more is the mass of the body , the greater will be the inertia.
What is external force?External force is the force applied by external agents on the body.
