It kills the plant so no mineral salt
Answer:
respond to its environment
Explanation:
Answer:
Root hair cells are adapted for taking up water and mineral ions by having a large surface area to increase the rate of absorption.
Explanation:
Interferons
Virally infected cells produce and release small proteins called interferons, which play a role in immune protection against viruses.
<h3>What are Interferons ?</h3>
Interferons prevent replication of viruses, by directly interfering with their ability to replicate within an infected cell.
- They also act as signalling molecules that allow infected cells to warn nearby cells of a viral presence – this signal makes neighbouring cells increase the numbers of MHC class I molecules upon their surfaces
- So that T cells surveying the area can identify and eliminate the viral infection.

Answer:
Mutations that activate the kinase portion of the receptor result in a receptor that is constantly phosphorylated. This causes constitutive activation of downstream signaling and the resulting cell growth and proliferation
Explanation:
The epidermal growth factor receptor (EGF receptor) is a type of receptor tyrosine kinase that recognizes and binds different ligands (including the Epidermal growth factor), which triggers its dimerization through the interaction of the extracellular domains. In humans, several mutations in genes encoding receptor tyrosine kinases have been associated with cancers. It is for that reason that mutated receptor tyrosine kinase genes are well-known oncogenes. Moreover, mutations in several receptor tyrosine kinase genes that lead to constitutive activation by phosphorylation have also been identified. In this case, it is expected that a mutation in the EGF receptor leads to constitutive phosphorylation of the mutant protein, constitutively activating downstream signaling.
