Answer:
receptor tyrosine kinase activity.
Explanation:
Theses are the receptors present on the cell surfaces of cells with affinity fpr specific polypeptides- gwoth factors, hormones and cytokines. They are regulators of normal cellular processes. E.g e development and progression of cancer in most cells
Mutation in their protein sequence leads to faulty protein expression.
Edwin Hubble used the Doppler effect to determine that the universe is expanding. After years of scientific research and observation of different celestial bodies through a telescope, Hubble found that the light from distant galaxies was shifted towards the red end of the spectrum. This red shift indicates that stars are moving away from us and from each other. This phenomenon is called the 'expansion of the universe', also known as the big band theory.
The group of animals that group or live together are called
analogies. Analogies are structures that
result from convergent evolution - species from different evolutionary branches
= no shared ancestry similar appearance examples - wings of bees and bats,
Australian mole an North American mole - both look similar, they occupy the
same niche.
