Answer:

B. It refers to the idea the prehistoric oceans combined with lightning formed the building blocks of life.

Explanation:

  • One of the widely accepted theory of evolution of life is the  theory of Chemical evolution.
  • According to this theory, the conditions of prebiotic earth were favourable to a sort of continuing chemical evolution. that gave rise to a special class of organic molecule.
  • Organic molecules must have evolved before the origin of life from primordial atmosphere which was anoxic and chemically reducing.
  • Subsequent to the abiotic synthesis of organic matter, seas were converted into a hot dilute pebiotic soup.
  • This theory was devised by John Haldane and Alexander Oparin.
  • They proposed that on addition of energy to the gases of primitive atmosphere building blocks of life will be created.

Covalent bonds do not gain or lose electrons, but rather share electrons. True or False?
Svetllana [295]
This is true, a covalent bond is always a shared pair of electrons between 2 atoms. This is done to stabilize both atoms but making their outer energy level more or totally complete with electrons.

Answer

1. The vascular and dermal tissues

2. Protein capsid

Explanation

Dermal tissue present in plants offer the first defense mechanism against physical damage which could be caused by insects and infections.The dermal tissue covers the outside parts of a plant except in woody shrubs and tree which are protected by the bark. Vascular tissues in plants are responsible for the transportation of water and nutrients that are vital in cell repair and growth.Through vascular tissues, the plant obtains nutrients important for the restoration of the damaged cells.

A capsid is the protein shell of a virus.It is composed of protomers which are subunits.Some viruses are enveloped by a capsid coated with a lipid membrane called the viral envelop.The main function of a capsid is to protect the genetic material of a virus while interacting with the host environment.
