Which conclusion about the origin of life could be drawn from the potential results of this experiment?






Life assembled from chemical building blocks.


Life began when water vapor became electrified.


Life evolved from the DNA of simple unicellular organisms.


Life began when salt water caused a mutation in an ancient virus.

Answer:

You can recover the dissolved salt by heating the water. When heated the water will evaporate, and the salt will be left. It's mass would be the same as at the beginning.

Answer:

Your Answer is A I believe

Answer:

water clarity

Explanation:

The factor that will best contribute to the measurement of environmental quality is : ( B ) 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

Answer:

B

Explanation:

B. Hydrosphere-Atmosphere

The hydrosphere comprises the totality of Earth's water. The atmosphere comprises the totality of Earth's air. The liquid water in the glass that was left outside evaporated, turning into gaseous water vapor that escaped the glass. The water as a liquid in the glass and as a vapor as a gas are both part of the hydrosphere. But once some of the liquid water became gaseous water vapor, that water became part of the Earth's atmosphere.

Answer:

more environments and i think they require less energy... but more environments for sure

Explanation:

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.

C. The pancreas triggers the development of secondary sex characteristics

Explanation:

Edge 2021

The statement in Heather’s report was not accurate C. The pancreas triggers the development of secondary reproductive characteristics.

The pancreas secretes digestive enzymes in the slender instincts, these enzymes produce endocrine secretions through the hormones and pass through the blood.

Endocrine cells called pancreatic islets secrete insulin and glucagon and have endocrine functions that are formed through the hormones and pass through the bloodstream.

Thus, option "C" is correct.

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).

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.

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.

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.

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.

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.

External force is the force applied by external agents on the body.

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.
