The provided question lacks the options, however, the options associated with the question is as follows;

A. translation

B. cellular respiration

C. active transport of ions

D. replication of chromosomes

Answer:

The correct answer is - D. replication of chromosomes.

Explanation:

During every cell division, either meiosis or mitotic the chromosomal DNA present in the nucleus is needed to be duplicated and the process that involves the duplication of this chromosomal DNA is known as replication of chromosome which takes place during the interphase of the cell division.

All other processes mentioned in the options are not involved or directly not involved in the processes. Translation involves the mRNA in the cytoplasm to produce amino acids with the help of ribosomes. Cellular respiration involves mitochondria and does not require DNA in the process.

If grasshoppers were removed from this food web, which organism would suffer the most, the bird or the baboon?
Mashutka [201]

Answer:

If the grasshoppers are removed from this ecosystem the bird will suffer the most.

Explanation:

On the presented food web we can see a food web that is complex and typical for the African savanna. As in all food webs, one organism is important for the survival of another organism or for the survival of numerous organisms. In this case, we have the grasshopper and its importance in the ecosystem, and which animal will be the most affected if it suddenly was not in this ecosystem anymore.

The bird and the baboon both feed on grasshoppers, but there is one big difference, and that is that the grasshoppers are the primary food source of the bird, while the baboon has other food sources as well. This means that with the grasshoppers being out of this ecosystem, the bird will have a very hard time surviving, and if it doesn't adapt quickly enough to feed on something else it will probably go extinct. The baboon, on the other hand, will be affected but not so dramatically as it will continue feeding on the other food sources, though it might suffer some smaller losses in its population.

Hola, me encanta el mundo forense, tengo 13 años y quiero estudiar eso. ¿Hay algún libro forense para aprender lo básico y todo
Elan Coil [88]

¡Hola a ti también! :)

Pido disculpas por si mi discurso le suena extraño; Estoy usando un traductor de Google porque solo sé un poco de español.

Hay muchos libros sobre medicina forense, que incluyen un libro llamado "Medicina forense para tontos", que probablemente sea un buen lugar para comenzar.  Si vive cerca de una biblioteca o una librería, entonces debería poder preguntarle a alguien que trabaje allí si puede ayudarlo a encontrar un par de libros para usted. Otra opción sería obtener una aplicación de algún tipo que le permita comprar / leer libros allí. Espero haber ayudado a algunos, o al menos haberles dado algunas ideas nuevas.
