After having one concussion you are more likely to have another — some doctorsestimate you increase your risk up to three times. There are two reasons why your risk increases: carelessness and brain chemistry.
Answer:
We have 23 pairs each with 50/50 probabilities. That works out to 223 possible combinations of gametes from one human individual.
Answer:
The majority of marine organisms are found in coastal regions.
Explanation:
The majority of marine organisms are found in coastal regions because ocean flows bring nutrient-rich water into coastal areas. Marine coasts are the type of environments that change through the weathering process and change in sea levels. Coastlines mostly consist of continental shelves that contain relatively shallow waters of having 200-meter depths only.
Since water is shallow here, photosynthetic processes are possible for marine life, which attracts more organisms to their primary food sources. Since the land is near shallow waters, discharges of nutrients from the soil are brought into the sea for the marine organisms so that they can use it. Aside from these reasons, cyclic upwellings in the sea also provide fresh and nutrient-rich waters for several species.
Answer:
¿Cómo pasa la comida por el cuerpo?
Los alimentos se mueven a través de su tracto gastrointestinal mediante un proceso llamado peristalsis. Los órganos grandes y huecos de su tracto gastrointestinal contienen una capa de músculo que permite que sus paredes se muevan. El movimiento empuja los alimentos y los líquidos a través de su tracto gastrointestinal y mezcla el contenido dentro de cada órgano.

A a short strand of RNA that can complement and inactivate a sequence of mRNA
Answer: Option A
<u>Explanation:</u>
siRNA stands for small interfering RNA which has a set double-stranded RNA molecule. It is also called as silencing RNA or short interfering RNA. mRNA is a messenger molecule in the siRNA.
siRNA integrates into a protein complex known as RISC that tells the siRNA to target the RNA sequence. Then its double strands unwind into a short strand in that protein complex and remain bound to it.
It then directed by the RISC either to complement ( enhance) the mRNA molecule sequence or to degrade (inactivate) the mRNA molecule sequence.
