From the following, the example which is not of a cnidarian is Snail. Hence, the correct option is C.
What are Cnidarians?Cnidarians are the radially symmetrical soft bodied animals that belong to phylum Cnidaria of the animal kingdom. They are also called coelenterates. The snails belong to phylum mollusca.
They are all sea dwelling animals which have a hollow digestive cavity. Furthermore, they appear in either sessile polyp stage or moving medusa stage. Moreover, they are further divided in classes Schyphozoa, Anthozoa, Hydrozoa and Cubozoa. All having different characteristics.
They show both sexual and asexual reproduction. Also, their development is indirect, meaning the development takes place from a larval stage. They show the property of polymorphism and have cnidoblasts cells for defense. Hence, the correct option is C.

Which definition best describes an acid?
Answer:
A substance in a solution that releases and captures hydrogen ions, keeping the pH the same
Explanation:
A substance that may release a proton or hydrogen ion (H +) is referred to as an acid.
What is acid?Hydrogen ions and chloride ions are created when hydrogen chloride, which is suspended in water, ionizes. A particle or ion that may produce a hydron (proton or hydrogen ion H+ is known as an acid.
Any hydrogen-containing material that has the ability to donate a proton (hydrogen ion) to another chemical is considered an acid. A base is a molecule or ion that can take up an acid's hydrogen ion.
Typically, sour tastes help to identify acidic chemicals. capable of forming a covalent connection with an electron pair on (a Lewis acid). Proton donors, also known as Brnsted acids, make up the first level of acids.
Therefore, that may release a proton or hydrogen ion (H +) is referred to as an acid.

explain in your own words : Are mutations good or bad for a population
Answer:
Mutational effects can be beneficial, harmful, or neutral, depending on their context or location. Most non-neutral mutations are deleterious. In general, the more base pairs that are affected by a mutation, the larger the effect of the mutation, and the larger the mutation's probability of being deleterious.Which of the following are considered parts of

NASA has discovered a lifeform on another planet! They have called you to help them identify what kind of organism it is. Which features suggest that the lifeform is eukaryotic rather than prokaryotic
Answer:
Nucleus, Linear Chromosomes, membrane-bounded organelles, golgi apparatus, mitochondria
Explanation:
All life forms consists of either prokaryotic cells or eukaryotic cells.
An Eukaryotic cell is a cell which has a nucleus. They are a group of organisms which have a nucleus that is enclosed inside a nuclear envelop. They contains member bound organelles which includes the mitochondria, endoplasmic reticulum and the nucleus. Some of the examples of eukaryotic cells are plants, animals, protists, fungi, etc.
Where as a prokaryotic cells does not contains a nucleus. They do not have a member bound organelles. Prokaryotic are unicellular. Some examples are bacteria, archaea, etc.
In the context, I would look for features such as membrane bounded organelles, mitochondria, nucleus, golgi apparatus, etc. in the new life form that has been discovered in the new planet to identify them as eukaryotic.

Describe Protein denaturation and it's effects
Answer: Denaturation involves the breaking of many of the weak linkages, or bonds (e.g., hydrogen bonds), within a protein molecule that are responsible for the highly ordered structure of the protein in its natural (native) state. Denatured proteins have a looser, more random structure; most are insoluble Denaturation involves the breaking of many of the weak linkages, or bonds (e.g., hydrogen bonds), within a protein molecule that are responsible for the highly ordered structure of the protein in its natural (native) state.

Which of the following statements is correct?
Your eyes look different than your liver, because the cells that make up these
organs have different genes.
o As cells and tissues differentiate, they lose the genes they do not need.
O All cells have the same genes, but different genes are active in different cells.
Cells do not have DNA.
Answer:
The statement that is correct is that all cells have the same genes, but different genes are active in different cells.
Explanation:
Differentiation or specialization is a function that cells possess and is what allows them to have different types of cells and tissues.
Cell differentiation depends on genetic regulation, a mechanism that determines the specific genes that are expressed in a cell or tissue type.
All cells contain the same DNA, which is organized into chromosomes and contain the genes that determine specific characteristics. There is cell differentiation because some genes can be expressed and others are suppressed, all due to genetic regulation.
The other choices are wrong because:
The eyes look different from the liver, because they have the same genes, but only some are expressed. Differentiated cells and tissues do not lose their genes. All cells have DNA.In order to dilute a solution,you need to____________________

Which structures can be found on a protist but not on a fungus?
Answer:
See the answer below
Explanation:
First, there is a need to know that protists are unicellular, animal-like living organisms while fungi are unicellular/multicellular, achlorophyllous, and heterotrophic decomposing organisms.
A typical protist may have a plant-like cell wall or just an animal-like cell membrane without a cell wall. This is unlike fungi whose structure includes a rigid, chitin-containing cell wall.
Most protists also have locomotive structures that enable them to be motile. For example, the amoeba has pseudopodia, the paramecium has cilia, while the euglena has flagella. Fungi generally are immotile, that is, they do not have any locomotive structure that enables them to move.
Some protists have two vacuoles - contractile and food vacuoles - which assist them in essential functions such as osmoregulation and nutrition. Unicellular fungi such as yeasts only have a single vacuole.
Some protists such as the euglena have chloroplast which enables them to photosynthesize in addition to other forms of nutrition. Fungi generally, however, are achlorophyllous. They lack chloroplast/chlorophyll in any form.
