The correct answer is C. The three germ layers.
The feature which is only shows higher invertebrates as compared to lower invertebrates is referred to s the three germ layers.
Germ layers is termed as the primary layer of cells which forms during embryogenesis. Three germ layers which are invertebrates are pronounced as eumetazoans which includes animals.
An example of an animal which produces two germ layers is Cnidarian which are endoderm and ectoderm and makes them diploblastic.
Chordates produce third layer which is mesoderm and makes triploblastic. Germ layers they give rise to all animals organs and tissues under process known as organogenesis.
The correct option is this: THE DISCOVERY OF CODONS.
<span>Codons refers to a sequence of three DNA or RNA nucleotides which corresponds to a particular amino acid or a stop signal during protein synthesis. Thus, the genetic codon is used to translate the information that are encoded within genetic materials into proteins. The genetic codons was discovered by Marshall Nirenberg and Heinrich Matthaeis, who deciphered the entire genetic codes by matching amino acids to synthetic triplet nucleotides.</span>
False , it will always point away because the radiation pressure of the sunlight
The answers are the following:
-Rust
- yellow mosaic
- blight
-Stalk rot
—Evidence—
•] Rusts are plant diseases caused by pathogenic fungi of the order Pucciniales.
•] Wheat yellow mosaic (usually called wheat spindle streak mosaic) is caused by a soilborne virus which also is transmitted by the soilborne fungus, Polymyxa graminis.
•] Blight spreads by fungal spores that are carried by insects, wind, water and animals from infected plants, and then deposited on soil. The disease requires moisture to progress, so when dew or rain comes in contact with fungal spores in the soil, they reproduce.
•] Fusarium stalk rot, primarily caused by the fungus Fusarium verticilliodes, is a common disease in the Midwest. This fungus also causes Fusarium ear rot and can infect roots, stalks, and leaf nodes. It is most common in hot, dry years.
