Which of the following is a true statement? a. Mammals were the prominent species just before the extinction of dinosaurs. b. Ma
Angelina_Jolie [31]

Answer:

The correct answer is B.

Explanation:

Option A is wrong. Mammals were not the prominent species before the extinction of dinosaurs because the mammal species that lived during the dinosaurs' era were so small that they only weighed several grams and occupied small areas as their habitats.

Option C is wrong. As dinosaurs became extinct, reptiles and "birds" remained as their descendant which evolved to some of the species that we know today.

Option D is wrong. Pangea started to break up to form the geographic isolation for the diversion of many species around 175 million years ago.

So the correct answer is B. Massive extinction disrupts and changes the food chain in such a big way that it triggers a domino effect that leads to species adapting to their new environment and diversifying thus forming new species in the process.

I hope this answer helps.

After a signal binds to a signal receptor, the next step is transduction. Why is the signal transduction step necessary ls7c wee
mars1129 [50]

Answer:

Signal transduction is what allows cells to respond to the influences of the environment around them, providing cells with proper growth and normal cell function.

Explanation:

Living organisms have developed a wide variety of complex processes to transmit signals from the outside to the inside to elicit an adequate cellular response. Defects in these molecular pathways can lead to very different disorders, such as diabetes, cancer, and psychotic illnesses. Signal transduction is the process by which a cell converts a certain signal or external stimulus into another signal or specific response, that is, it is the mechanism by which a cell responds to the stimuli it receives from the environment through diffusion. of those signals to its internal compartments. First, a signaling molecule (also called a ligand) needs to activate a specific receptor on the cell's membrane or cytoplasm. Ligand-receptor binding is very specific; they are recognized as a key and a lock. Second messengers are molecules that allow the received signal to be amplified at the intracellular level. The binding of a ligand to the receptor can generate hundreds of second messenger molecules that, in turn, can modify thousands of effector molecules and give rise to different responses. Cells recognize, integrate, and respond to multiple signals from their environment due to signal transduction, providing cells with a normal cell function.
