Answer:
Process that involves rearrangement of the molecular or ionic structure of a substance, as distinct from a change in physical form or a nuclear reaction Hope this helps! Have a great day!
water evaporation.
c.
water precipitation.
b.
water condensation.
d.
the water cycle.
The correct answer is option option D
The movement of water from ocean to atmosphere, then land and back to the ocean. This whole process forms a cycle called as water cycle.
It assures the movement of water from land to sky and back from the sky to land. The water from the ocean and sea evaporates into the atmosphere and goes into the sky to form clouds.
These clouds causes rain (precipitation) which falls on the land and then the water flows back to the ocean.
This cycle is known as water cycle.
??
bears hibernate during the winter.
B)
the base of the food chain is seasonal.
C)
available energy is lost from one trophic level to the next.
D)
light that supports photosynthesis is limited during certain times of the year.
Answer:
The correct answer would be C) available energy is lost from one trophic level to the next.
It is the universal law that the energy is lost when transferred from one trophic level to the next.
It is because most of the energy present at any trophic level is used by the organisms for their biological processes such as locomotion, reproduction et cetera. Due to this, most of the energy is lost as heat in the surrounding environment.
In the given food chain, the bears are present at the highest trophic level and thus they would get minimum energy.
Thus, the ecosystem can provide only a limited amount of energy to the bears due to which the ecosystem can support a limited number of bears.
a. Sponge
b. worm
c. mollusk
d. Cnidaria
The body symmetry of each organism you mentioned is as follows:
Sponge: Asymmetrical
Sponges have no definite body symmetry. Their body structure lacks any organized pattern or axis of symmetry.
Cnidaria (e.g., jellyfish, corals, sea anemones): Radial Symmetry
Cnidarians exhibit radial symmetry, which means their body parts are arranged around a central axis. They have multiple planes of symmetry, allowing them to be divided into equal halves through their central point.
Worms (e.g., earthworms): Bilateral Symmetry
Most worms, including earthworms, exhibit bilateral symmetry. This means their bodies can be divided into two equal halves along a single plane, resulting in a left and right side that are mirror images of each other.
Mollusks (e.g., snails, clams, octopuses): Bilateral Symmetry
Mollusks also have bilateral symmetry. Their bodies can be divided into two equal halves along a single plane, resulting in a left and right side that are mirror images of each other.
It's worth noting that while sponges and cnidarians have simple body plans and display asymmetry or radial symmetry, worms and mollusks have more complex body structures, and their bilateral symmetry is an adaptation that allows for greater mobility and more efficient movement in their environments.

Answer:No
Explanation:
They do not have a nuclear membrane surrounding their cellular DNA
Answer:
Prokaryotes, such as bacteria, do not have a nuclear membrane surrounding their cellular DNA, so cell division is happens differently than in eukaryotes. Even though the cell does not undergo mitosis, the end result is the same.
