The law of conservation of mass was created in 1789 by a French chemist, Antoine Lavoisier. ... For example, when wood burns, the mass of the soot, ashes, and gases, equals the original mass of the charcoal and the oxygen when it first reacted. So the mass of the product equals the mass of the reactant
What is the graphical representation of age structure known as?
OA.
age group
OB. age graph
Oc. age scale
OD
age pyramid
Answer:
The graphical representation of the age structure is known as age pyramid (option D).
Explanation:
The age pyramid or more properly called population pyramid groups all the individuals of a population, distributing them by age and sex. The name is due to the fact that, in general, the bar graph resembles a pyramid.
The age groups are distributed in the pyramid by age from lowest (bottom) to highest (top), with the sexes forming the sides of the pyramid.
In emerging countries the population is relatively young, which makes the base of the pyramid wide, narrowing as it moves up to the upper age groups.
Age group, age graph or age scale do not correspond to the population graph where the age and sex structure of a population are expressed.

Explanation:
What happens to energy that is transmitted through or reflected off a material?
When light is transmitted through or reflected off a material, the light is converted into heat.
What is light?Light is an entity that make things visible to eyes. It is an electromagnetic radiation. It can not be produced or end, it's just converted into one form to another form.
The item may absorb the light wave, in which case its energy is changed to heat. The object might reflect the light wave. Additionally, the object might transmit the light wave. When this happens, things often selectively absorb, reflect, or transmit certain light frequencies.
The light is passed through some objects and do not get passed through some objects. The light that do not pass through an object is reflected back to the same place, but when it is not reflected, it converts into heat.
Therefore, the light is converted into heat when it is not reflected.

A lichen is an organism that structurally appears to be a single organism. But a lichen is actually two different organisms—a fungus and green algae—living together as one organism. The fungal partner derives its nutrition from the photosynthesizing algae. How does a lichen differ in its photosynthetic activity from Elysia chlorotica, the sea slug that’s considered to be a photosynthesizing animal?
A.
In lichens, the fungi photosynthesize on their own, while Elysia chlorotica forms a relationship with a photosynthesizing plant.
B.
In lichens, the relationship with the algae lasts throughout the life cycle, but in Elysia chlorotica, the relationship occurs only during the immature juvenile stage of the slug’s life cycle.
C.
Lichens can photosynthesize only because of the living algal partner, while Elysia chlorotica incorporates chloroplasts from algae into its cells.
D.
In lichens, the association between the fungi and algae is permanent, while Elysia chlorotica associates with a photosynthesizing organism only when it requires food.
Answer:
B. Cycle
Explanation:
Lichen performs photosynthesis with the assistance of an algal partner, but Elysia chlorotica incorporates the chloroplast from an algal partner, which is how lichens vary from Elysia chlorotica in this regard, hence option C is correct.
How does lichen photosynthesize?A process known as photosynthesis is one in which green plants and some photosynthetic algae produce their own food, glucose, using carbon dioxide and water in the presence of light.
Lichen is a symbiotic association between an algal component that produces food and a dominant partner fungus that gives the lichen its thallus form and fruiting bodies. A particular species of mollusc called Elysia chlorotica uses the chloroplast of an algal partner to carry out the photosynthesis process.
Therefore, Lichens can photosynthesize only because of the living algal partner, while Elysia chlorotica incorporates chloroplasts from algae into its cells, hence option C is correct.

Which statement describes a law based on a tested hypothesis explains how the process occurs describes something about the natural world subject to change as new evidence is discovered
Answer:
based on a tested hypothesis
Explanation:
Laws are generally based on tested hypotheses.
Theories are first derived from repeatedly tested and proven hypotheses. Scientific laws are derived from theories that have been proven to be true over a wide range of phenomenon. Hence, laws are overwhelmingly proven facts that cannot be changed.
Scientific laws are internally consistent, compatible with evidence, and are testable against a wide range of phenomenon. However, they can be reviewed as more evidences emerge that have not been known before.

Explain how mitosis maintains the chromosome number
of the original cells when forming new cells.
Relation between mitosis and chromosomes:
During mitosis, a cell duplicates all of its contents, including its chromosomes, and splits to form two identical daughter cells. Because this process is so critical, the steps of mitosis are carefully controlled by certain genes. As they move, they pull the one copy of each chromosome with them to opposite poles of the cell. When mitosis is not regulated correctly, health problems such as cancer can result.When a cell divides by way of mitosis, it produces two clones of itself, each with the same number of chromosomes.
