Answer: The correct answer is- E) structural framework.
Fibrous proteins are water insoluble, elongated filamentous like structures that that provide structural framework ( they have special types of helices in their structures) to the cells or tissues of organisms.
They contain repetitive amino acid sequences in their structure that provides strength to the structure.
They are very less sensitive to any change in pH, temperature, as well as enzymatic digestion.
They are usually involved in the formation of connective tissue.
Example of fibrous protein- Actin, myosin, elastin, keratin.
Answer:
The correct answer is A. radial symmetry with only two germ layers and one digestive opening.
Explanation:
Phylum Cnidaria consist of aquatic organisms and they have special feature called Cnidocytes. Cnidocytes are tentacles used to capture the pray. All organisms of phylum are bilateral and have two body layers called Endoderm and Ectoderm. A jelly like material called mesoglea is present between ectoderm and endoderm. Their digestive system has no organs and their is a single opening to capture the food. As they have only single opening in digestive system it is also used to excrete the digested food out of the body.
Answer: a) genetic
b) environmental
Explanation:
Phenotype is a function of genotype and environment
P=G+E
Where P= phenotype
G=Genotype
E=Environment
The phenotype of an individual i.e what is seen or expressed is a product of the gene he or she carries and the environment they occupy.
Gene is the genetic makeup of an individual.
The Identical and fraternal twin are products of their gene and the environment such as uterine environment, parenting style they grow, Identical twins have 100% of identical genes while fraternal twin have 50% gene in common
Hence, the difference is a function of their genetic makeup and the environment they grow.
Culture and evolution can also be regarded as part of the environment.
