Answer: D. Gradually, as generations of elephants continued to selectively use and develop their trunks.
Explanation: Lamarck believed that organisms pass on traits to their offspring that they had acquired through use or diuse during their lifetime. In this example, the theory would be that over time, elephants used their trunks in such a way that they became long and powerful.

The answer to this question would be: <span>b.electromagnetic or weak nuclear
</span>
The electromagnetic force can be repulsive or attractive because it was influenced by the magnetic charge. The same charge (positive with positive) will be repulsive but different charge will be attractive(negative and negative). The gravitational force will always be attractive, not repulsive.
Weak nuclear can do both like electromagnetic force.
Answer:
Enzyme-linked
Explanation:
The cell surface receptors that have intracellular domains associated with enzymes are called enzyme-linked receptors. The added molecule was water-soluble and cannot pass through the membrane to bind to intracellular receptors. Binding of the added molecule to the enzyme-linked receptor led to the activation of associated enzymes to generate the response (down-regulation of expression of the target gene).
Examples of enzyme-linked receptors include tyrosine kinase receptors. Binding of the signaling molecule to these receptors triggers phosphorylation of the intracellular domain which in turn transmits the signal to the cytoplasmic messenger.
