Answer:
If I'm not mistaken the answer should be A,C, and E.
Explanation:
B. Smooth endoplasmic reticulum
C.Rough endoplasmic reticulum
D. Ribosomes
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.

B)reproduction
C)use of a genetic code
D)response to external stimuli
Answer:
The correct answer is option D) "response to external stimuli".
Explanation:
The phenomenon of tree shedding their leaves during the autumn months is an example of plants response to external stimuli. The deciduous trees start shedding their leaves when light levels and temperatures drop, as a result of the flow of auxin being reduced and the levels of the hormone ethylene rise in the leaves. This process allows the trees to survive winter by conserving resources and protecting from being blown by the winds.
b) metaphase)
c)anaphase
d) telophase
I need help!
Prophase: Replication of chromosomes and chromosome become visible x shapes.
Metaphase: Chromosomes align at the equator of the cell and spindle fibers attach to each sister chromatid.
Anaphase: Spindle fibers pull the sister chromatids away from each other to the opposite sides of the cell.
Telophase: New separate nuclear membranes form around the different sets of chromosomes and the chromosomes unwind, the spindle fibers start breaking down and and the cell begins to pinch together to separate into two new cells.
Ladies and gents this has been Mitosis.
Answer:
The organ above is responsible for filtering wastes from the digestion of proteins and cleaning the blood of excess salts. It is found in the lower back. It is thekidney and is part of the excretory system.
Explanation:
Kidneys are a pair of a bean-shaped organ which are located in the back abdominal area, under the rib cage. The major function of kidneys is to filter waste from the blood. The waste materials from the food we consume is filtered by the kidneys. Other functions of the kidney include maintaining the fluid balance of the body.
The kidney is one of the major organ of the excretory system along with the ureters and urinary bladder.
