Answer:
C) Nucleic Acid
D) Capsid
Explanation:
A virus is structure that is dependent on a living host to replicate itself. Viruses are majorly pathogenic in nature and have a structure that is made up of two parts namely: nucleic acid and capsid.
The nucleic acid, which can either be RNA or DNA holds the genetic information of the virus while the capsid is a protein coat that enclosed and protects the virus' genetic material. The capsid is also used during the infection life cycle of a virus where it helps the virus to attach to receptor cells on the host's cell membrane.
One example:
Energy moves through an ecosystem through different organisms. For example, plants can absorb energy from the sun. Animals, such as grasshoppers, can eat the plants and the energy goes to them. Progressing higher up the food chain, the energy continues to transfer through different animals - grasshoppers can be eaten by mice, mice by snakes, snakes by eagles, etc. etc.
Answer:
option A:The kinase is active only when Tyr527 is dephosphorylated and Tyr416 is phosphorylated.
Explanation:
Answer:
Gastrulation leads to the formation of the three germ layers that give rise during further development to the different organs in the animal body. This process is called organogenesis. Organs develop from the germ layers through the process of differentiation.
