Answer:
It is essential for living organisms to maintain a non-equilibrium state in the concentrations of oxygen and carbon dioxide to facilitate gas exchange. If equilibrium is reached, both respiration and photosynthesis would cease.
Explanation:
- Gases flow from areas of higher concentration to lower concentration along their gradients.
- If organisms achieve equilibrium in carbon dioxide and oxygen levels, gas exchange into and out of cells would stop.
- Equilibrium signifies that gas concentrations equalize on both sides, halting any movement.
- Should gas exchange come to a standstill, respiration and photosynthesis in plants, as well as respiration in animals, would completely halt.
Answer:
Sister chromatids are identical copies of chromatids from chromosomes. They are typically produced through the semi-conservative replication of a single chromosome's DNA. Thus, they can be viewed as'photocopies' of the original parental chromosomes, linked together at the centromere.
They are entirely identical in every aspect, sharing the same genes and allele configurations.
Still, minor variations can occur between the identical sister chromatids due tomutations fromerrors during replication, and differences can also arise in the lengths of telomere repeats.
Non-sister chromatids differ as they arise from separate haploid sex cells during fertilization. These chromatids come from distinct parents and possess different genetic compositions since they do not lie on the same homologous chromosomes. This is why crossing-over results in genetic variation.
However, they may still exhibit genetic similarities if they are part of homologous chromosomes. This is because Synapsis of the bivalents in these chromosomes permits the exchange of genetic material through crossing-over between non-sister chromatids, thereby sharing identical genetic traits.
Explanation:
Euglena presenta un color verde gracias al clorofila que se encuentra en los cloroplastos de este organismo, y la estructura corporal situada en su base se llama flagelo.
Explanation:
Las Euglenas son especies que habitan en aguas dulces y saladas, y se encuentran en gran cantidad en cuerpos de agua interiores, donde pueden proliferar y teñir la superficie del agua de zanjas y estanques de un color verde.
Este color verde que producen se debe en gran parte a la clorofila que se halla en sus cloroplastos, la cual es el pigmento responsable del color verde. Este pigmento también es el causante de la coloración en este caso.
Las Euglenas cuentan con una estructura corporal especializada, ubicada en la base de su cola, que les permite moverse.
Esta estructura especializada se denomina flagelo.
The appropriate answer is - C. genus and species. The scientific nomenclature of an animal reflects its genus and species. The first part denotes the genus, which in this instance is Canus, while the second part indicates its species, here being nipponicus. All living beings are categorized systematically: kingdom, phylum, class, order, family, genus, species. For instance, if we consider the wolf as an example, its classification is as follows: Kingdom: Animalia, Phylum: Chordata, Class: Mammalia, Order: Carnivora, Family: Canidae, Genus: Canis, Species: C. Lupus.
Jupiter is likely the answer. Besides that, there's really nothing else.
