The Origins Of The Word 'Cell' In the 1660s, Robert Hooke looked through a primitive microscope at a thinly cut piece of cork. He saw a series of walled boxes that reminded him of the tiny rooms, or cellula, occupied by monks. these chambers he used the word 'cell' to describe them, because they reminded him of the bare wall rooms where monks lived.
Vega is approximately twice as hot as Pollux. Pollux has a surface temperature of 4,865 degrees Kelvin while Vega burns bright with a surface...
Answer:
Vega is hotter than Pollux
Explanation:
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.

The first step will be amplifying the DNA sample using the PCR machine. Only small sample may be used for DNA fingerprinting. the DNA is being amplified by a way f heating so as it can denature to single-stranded where tag polymerase is being synthesized by an enzyme.
step2. Take the restriction enzyme then and also the product then mix them together.
step3. by use of gel electrophoresis you learn the sample.
step 4. both results for the fingerprints and the ones you were testing so as to find if there is any banding.
Answer:
A frameshift mutation is produced either by insertion or deletion of one or more new bases. Since the reading frame begins at the start site, any mRNA produced from a mutated DNA sequence will be read out of frame after the point of the insertion or deletion, yielding a nonsense protein
