Answer:
the relationship between stress and strain that a particular material displays
. it's unique for each material
. it's is found by recording amount of strss at different values of strain. it is the stress point at which a specific material breaks under a given stress in a typical stress-strain curve , the breaking strength is less than the ultimate strength
Explanation:
Answer:
In the search of food for their survival.
To protect themselves from their enemies.
To get a suitable temperature for their reproduction.
To get a perfect habitat to increase their survival rate.
To get more prey and a safe place.
In search of a better climate that suits their body.
When an oncogene is turned on and is not balanced through suppression
of tumor suppressor gene, the normal
cells become cancerous and divides unregulated.
Normal cells differentiate while cancer cells do not. Additionally,
while normal cells respond to endocrine
and paracrine signals from neighboring cells, cancer
cells do not. Cancer cells have malfunctioned
apoptosis process due to a malfunctioned p53
tumor suppressor gene. Therefore they
continue to divide even when they have damage to their DNA. Cancer cells metastasize because, unlike normal cells, they do not produce an adhesive molecule that allows the cells to adhere to one another to form tissue.
Answer:
thamalus
Explanation:
Based on studies conducted by various neurologists, it can be said that in this situation that information was most likely first routed to the thamalus. This is a part of the brain that relays motor and sensory information to the cerebral cortex. It is also responsible for regulating sleep, consciousness and even alertness. Which is what was triggered (alertness) when you saw the spider crawling up your leg.
Answer:
- multiple pathways
- ligands/signaling molecules
- inorganic phosphate
- inactive relay proteins
Explanation:
Receptor Tyrosine Kinase:
- Receptor tyrosine kinase (RTK) is the largest class of enzyme linked cell surface receptors.
- When a growth factor or a ligand binds to two neighboring RTK receptors, the two receptors bind together and form a dimer.
- This change in the conformation of the RTKs activates the associated tyrosine kinase enzymes.
- Tyrosine kinases break down ATP to ADP and phosphorylate the RTKs. Cross phosphorylation between the receptors helps activate multiple tyrosine kinases on the neighboring RTK.
- Once phosphorylated, the cytoplasmic ends of the RTKs are available for docking by relay proteins or signaling molecules with an SH-2 domain.
