Answer:
B (nematocysts)
Explanation:
A nematocyst is a long, thin, coiled stinger. It has a barb that may inject poison. These tiny poison "darts" are propelled out of special cells. They are used to attack prey or defend against predators.
Have an awesome day friend! :D
Answer:
Gene: The hereditary material made up of alleles.
Alleles: The alternative forms of a gene.
Dominant: An allele or trait that masks the effect of recessive allele or trait.
Recessive: An allele or trait that gets suppressed by the dominant allele or trait.
genotype: The genome of a particular organism of the genes which make up an organism.
phenotype: The physical traits or characteristics of an organism.
test- cross: A cross in which the dominant and the recessive trait offsprings are crossed to depict whether the dominant organism is homozygous or heterozygous.
law of independent assortment: Alleles of different genes get assorted independently into gametes.
law of segregation: allele pairs segregate during gamete formation and unite at the time of fertilization.
product rule: Independent evens can be calculated by multiplying the independent probabilities.
Addition rule: The probability which shows that one event would occur in a mutually exclusive event.
co-dominant: When the dominant and the recessive trait occur and the organism shows both the characteristics of the dominant and the recessive trait.
incomplete dominance: when the dominant trait is not fully dominant over the recessive trait. As a result, individuals are produced which show neither the dominant or the recessive trait. A new trait is developed in them.

Answer:
lacks a well defined nucleus
lacks cell organelles.
Answer: All membrane lipids are amphipathic
Explanation:
The membrane lipid molecules are amphathic in nature which states that they are both hydrophobic and hydrophillic part. The lipid bi layer has been found tot be the most widely found in cell structure.
The structure is made of phosphorus and lipids and hence called as phospholipids.
The amphipathic nature of the lipids allows it to assemble spontaneously into bi layers even under the artificial conditions.
hence, all the lipids in the cell membrane or membranes are amphipathic in nature.
